2.5 Grounding, shielding

In order to comply with Part 15 of the FCC-regulations applicable to devices of Class B, the system mustbe grounded. Grounding is also the condition for the validity of the technical specifications stated.

Use of the desktop power supply unit, included in the package, ensures proper grounding via the plug'sprotective earth terminal: in the supply unit's LEMO-plug, the supply voltage's (-) pole as well as the shieldand plug enclosure are connected to the cable's ground.

The DC-supply input on the device itself (LEMO-socket) is galvanically isolated, i.e. isolated from thehousing!

Also, all signal leads to the device must be shielded and the shielding grounded (electric contact betweenthe shielding and the plug housing "CHASSIS"). To avoid compensation currents, always connect theshielding to one side (potential) only.

NoteWhen using multiple devices connected via the Sync terminal for synchronization purposes, ensure thatall devices are the same voltage level. Any potential differences among devices may have to be evenedout using an additional line having adequate cross section.Alternatively it is possible to isolate the devices by using the module ISOSYNC, see also chapterSynchronization in the imcDevices manual.

2.6 Power supply

The device is powered by a DC-supply voltage which is supplied via a 2-pole LEMO-plug (type designation:FGG.1B.302 CLAD ).

The permissible supply voltage range is 10 ... 36V (DC) at 20W max. consumption. The product packageincludes a corresponding desktop supply unit (24V , DC) as an AC-adapter for mains voltage (110 .. 240V50/60Hz).

NotePlease note, that the operation temperature of the desktop supply is prepared for 0°C to 40°C, even ifyour measurement devices is designed for extended temperature range!

The package also includes a cable with a ready-made LEMO-plug which can be connected to a DC-voltagesource such as a car battery. When using this, note the following:

Grounding of the device must be ensured. If the power supply unit comes with a grounding line, itwould be possible to ground the system "by force", by making a connection from this line to the plugenclosure (and thus to the device ground). The table-top power supply unit is made to allow this.This manner of proceeding may not be desirable because it may be desirable to avoid transientcurrents along this line (e.g. in vehicles). In this case the ground-connection must be made to thedevice directly. For this purpose a (black) banana jack ("CHASSIS") is provided.

The feed line must have low resistance, the cable must have an adequate cross-section. Anyinterference-suppressing filters which may be inserted into the line must not have any series inductorgreater than 1mH. Otherwise an additional parallel-capacitor is needed.

17General Notes

2.6.1 Main switch

The device's main switch for the CL-devices and CS-8008 is a rocker-switch which must be presseddown on the "ON"-side (upper portion) for approx. 1 sec. to achieve activation. The other CS-devices' mainswitch is a standard switch.

The ON state is indicated by the green "POWER"-LED flashing. If the device boots correctly, three shortbeep-tones are emitted together with blinking of 2x 2LEDs.

To switch the device off, press the rocker switch down on the OFF-side (lower portion) for approx. 1 sec.This causes the device to not be deactivated abruptly during a running measurement. Instead, any files onthe internal hard drive involved are closed before the device switches off by itself. This process takes up to10sec. Holding the "OFF"-side of the switch down is not necessary! If no measurement is currently running,it takes only approx. 1second for the device to be deactivated.

2.6.2 Remote control of the main switch

PIN configuration of LEMO plug (FGG.0B.306.CLAD.52Z 6-pin)

The signal " SWITCH1" serves to run the device with the switch permanently bridged: when "ON" and"SWITCH1" are connected, the device starts as soon as an external supply voltage is provided. If thissupply is interrupted, the UPS keeps the device activated for the appropriate buffer duration in order toclose the measurement and files, and then the device deactivates itself. Starting the device on the internalbattery isn't possible in this configuration, but once it has started the device can run on the battery as abackup. This type of operation is specially designed for use in a vehicle, permanently coupled to the ignitionand not requiring manual control.

Any switch or relay contact used for this purpose must be able to bear a current of approx. 50mA at 10max. The reference voltage for these signals is the primary voltage supply .

2.7 UPS

2.7.1 Concept

An optional module for uninterruptible power supply (UPS) is available. This unit makes it possible tocontinue through a short-term outage of the mains power supply. It is especially useful in mobile settings(on board vehicles) in order to handle the drop in voltage from the vehicle battery which occurs at ignition.

The use of backup power from the battery is indicated by the control lamp "PWR" changing from green toyellow and the buzzer sounding.

The buffering of the power supply is provided by a built-in lead/gel storage battery (accumulator), which isrecharged during normal operation by the external power supply.

The UPS provides backup in case of power outage and also monitors its duration. If the power outage iscontinuous and if it exceeds the device's buffer duration (standard: 1sec.), the device deactivates itself.This is done in the same way as in the case of manual deactivation, i.e., any running measurements andpertinent files are closed, which can cause a delay of up to approx. 10s.

If the power outage isn't continuous but only temporary as in the case of a vehicle being started, the bufferduration monitoring always jumps back to the beginning.

Thus, a typical application of this configuration is in vehicles, where the power supply is coupled to theignition. A buffer is thus provided against short-term interruptions. And on the other hand, deep dischargeof the buffer battery is avoided in cases where the measurement system is not deactivated when thevehicle is turned off.

2.7.2 Buffering time constant and maximum buffer duration

The buffer time constant is a permanently configurable device parameter which can be selected as aorder option. It sets the maximum duration of a continuous power outage after which the device turnsitself off.

The maximum buffer duration is the maximum (total) time, determined by the battery capacity, which thedevice can run on backup. This refers to cases where the self-deactivation is not triggered; e.g., in case ofrepeated short-term power-interruptions. The maximum buffer duration depends on the battery's currentcharge, on the ambient temperature and on the battery's age. The device automatically deactivates itselfjust in time to avoid deep discharge of the battery.

19General Notes

2.7.3 Charging time

With an external supply voltage connected and the device activated (!), about 12W of power areeffectively available for the purpose of charging the internal buffer (backup) battery, up to 15W in the shortterm. The time needed for charging up for the desired buffer duration is thus given by:

T_Charge = T_Buffer * total power / 12W

Due to the inevitable self-discharge or leakage, the device should be run every few months at least for thepurpose of assuring that the UPS-storage battery is fully charged and at the ready.

2.7.4 Take-over threshold

The voltage threshold at which the storage battery takes over the power supply from the external source isapprox. 9.75V (8.1V for CS). The take-over procedure is subjected to an hysteresis to prevent oscillatingtake-over. This would be caused by the external supply's impedance. This inevitable impedance lets theexternal supply rise again, right after take-over to internal buffering. Hysteresis in the take-over thresholdwill prevent oscillations due to this effect. If, during supply from of the buffering battery, the external supplyvoltage rises as high as 10.9V (9V for CS), the external voltage takes over again from the buffering battery.

If you check these thresholds, note that when the supply voltage is overlaid with a high frequencyinterference or ripple-voltage, the minima are of key importance. In fact, the overlying interference could becaused by feedback from the device itself!

NoteThe voltage specification refers to the device terminals. Please consider the voltage drop of the supply line,when determining the voltage supply.

2.8 Rechargeable batteries

The unit comes with long-lasting lithium batteries (Type BR2032) requiring no special maintenance.Replacement of the battery can only be performed by the manufacturer in the framework of a systeminspection (maintenance) (recommended for every 3-7 years depending on field of application).

Devices which come with the optional USV-Function contain maintenance-free lead-gel accumulators (4xType LC-R061R3PG, Panasonic, 6x WPO.5-4 with CL). Charging these internal backup batteries isaccomplished automatically when the activated device receives a supply voltage. Due to the inevitableleakage of charge we recommend that the device be activated at least every 6 months to prevent thebatteries from dying.

For C-series (MP0,5-4 4V Pb accu) the manufacturer specifies 5-7 years @ T<20°C and less than 1 year@ 50°C, if the discharge is very little (Trickle-life).

In case the UPS is used a lot (many discharge and recharge cycles), the life time depends on how much(deep) it has been discharged (is the UPS buffering only for a short time or is the UPS dischargedcompletely every time?). The manufacturer specifies 200 cycles @100% discharging and 1200 cycles @30% and 25°C ambient temperature. (that should be true in general for all Pb accus.)

imc recommend maintenance every 2-3 years.

2.9 Fuses

The device supply input (10..36V DC) is equipped with maintenance-free polarity-inversion protection.No fuses or surge protection is provided here. Particularly upon activation of the device, high current peaksare to be expected. When using the device with a DC-voltage supply and custom-designed supply cable,be sure to take this into account by providing adequate cable cross-section.

The designated current inputs of the "Voltage channels" are protected from overvoltage by 100mA fuses.The fuse is not accessible and can only receive maintenance by the manufacturer.

The supply voltage for external sensors, whose outlet are the voltage or incremental encoder channels, is provided with maintenance-free electronic fuses (current-limitation).

2.10 Precautions for operation

Certain ground rules for operating the system, aside from reasonable safety measures, must be observedto prevent danger to the user, third parties, the device itself and the measurement object. These are theuse of the system in conformity to its design, and the refraining from altering the system, since possiblelater users may not be properly informed and may ill-advisedly rely on the precision and safety promised bythe manufacturer.

If you determine that the device cannot be operated in a non-dangerous manner, then the device is to beimmediately taken out of operation and protected from unintentional use. Taking this action is justifiedunder any of the following conditions:

the device is visibly damaged, loose parts can be heard within the device, the device has been stored for a long period of time under unfavorable conditions (e.g. outdoors orin high-humidity environments).

1. Observe the data in the chapter "Technical Specifications", to prevent damage to the unit throughinappropriate signal connection.

2. Note when designing your experiments that all input and output leads must be provided with shieldingwhich is connected to the protection ground ("CHASSIS") at one end in order to ensure high resistanceto interference and noisy transmission.

3. Unused, open channels (having no defined signal) should not be configured with sensitive input rangessince otherwise the measurement data could be affected. Configure unused channels with a broad inputrange or short them out. The same applies to channels not configured as active.

4. To measure voltages > 60V, only use insulated banana plugs (4 mm).

5. If you are using a internal device drive, observe the notes in Chapter 7 of imcDevices manual. Particularcare should be taken to comply with the storage device’s max. ambient temperature limitation.

6. Avoid prolonged exposure of the device to sunlight.

2.11 Storage

As a rule, the measurement device can be stored at temperatures ranging from -40 to +90°C. The followinglimitations apply in consequence of the manufacturer’s specifications.

Lead rechargeable batteries (-20 to 40°C)

Li-Ion rechargeable batteries (-20°C to 60°C)

Display (-20-85°C)

Mechanical hard disk (drives) (-20°C to 70°C)

2.12 Modularity

The devices belonging to the imc C-series are not modular systems. The modules are not to be replacedby other types.

21General Notes

2.13 Notes on maintenance and servicing

No particular maintenance is necessary.

The specified maximum errors are valid for 1 year following delivery of the device under normal operatingconditions (note ambient temperature!).

There are a number of important device characteristics which should be subjected to precise checking atregular intervals. We recommend annual calibration. Our calibration procedure includes calibration ofinputs (checking of actual values of parameters; deviations beyond tolerance levels will be reported), acomplete system-checkup, newly performed balancing and subsequent calibration (the complete protocolset with measurement values is available at an extra charge). Consult our Hotline for the price for systemcalibration according to DIN EN ISO 9001.

When returning the device in connection with complaints, please include a written, outlining description ofthe problem, including the name and telephone number of the sender. This will help expedite the processof problem elimination.

For questions by telephone please be prepared to provide your device's serial number and have yourimcDevices installation software, as well as this manual at hand, thanks!

The serial number, necessary power supply, interface type and software version included can bedetermined from the plaque on the side of the device.

2.14 Watchdog

All devices of the C-series come with the Watchdog function. When the Watchdog is activated the devicerestarts automatically if no interface processor activity is detected for a specifiable period of time. TheWatchdog normally is not active.

For further information see manual imcDevices chapter 13 miscellaneous\ troubleshooting.

2.15 Cleaning

Always unplug the power supply before cleaning the device. Only qualified service technicians arepermitted to clean the housing interior. Do not use abrasive materials or solutions which are harmful to plastics. Use a dry cloth to clean the

housing. If the housing is particularly dirty, use a cloth which has been slightly moistened in a cleaningsolution and then carefully wrung out. To clean the corners, slits etc. of the housing, use a small soft drybrush.

Do not allow liquids to enter the housing interior.

2.16 Industrial Safety

It is confirmed that our product as delivered complies with the provisions of the industrial safety regulation"Electrical Installations and Equipment" (BGV-A3).

This confirmation is for the sole purpose of absolving the company of the obligation of having the electricalequipment inspected prior to initial commissioning (§ 5 Clauses 1, 4 of BGV-A3). Civil liability and warrantyare not affected by this regulation.

22 imc C-series

imc C-series

2.17 Sampling interval

Among the system's physical measurement channels, up to two different sampling times can be in use.See the technical specifications for the smallest possible sampling time. The aggregate sampling rate ofthe system is the sum of the sampling rates of all active channels and can take a maximum value of 400kHz.

The sampling rates of the virtual channels computed by Online FAMOS do not contribute to the sumsampling rate. Along with the (maximum of) two "primary" sampling rates, the system can containadditional "sampling rates" resulting from the effects of certain data-reducing Online FAMOS-functions(ReductionFactor RF).

There is one constraint when selecting two different sampling rates: Two sampling rates having the ratio2:5 are not permitted (e.g. 2ms and 5ms). Any attempt to set sampling rates which do not comply withthis rule will cause an error message to be posted:

"The two active sampling intervals may not be in a ratio of 2:5. Error number: 365“

2.18 Synchronicity

If certain channels are to be correlated to each other, for instance, for the purpose of computing the power,it's vitally important that there not be a phase-offset between them, in other words, that they be capturedsynchronously.

One of the main features of the devices of the imc C-Series is that it can ensure this synchronicity, evenfor channels of different types and different sampling rates. The condition for this is, that the channels beconfigured with the same filter setting. The low-pass filters always cause a defined additional phase-offset.For a 1kHz low pass Butterworth filter, this phase-offset corresponds to a frequency-independent, constant"group delay" which is 663µs (for frequencies well below the cutoff frequency) .

Note that two channels having different sampling rates and both configured with the filter setting AAF donot have the same filter frequency!

23Properties of the imc C-Series

Properties of the imc C-Series

3.1 General

3.1.1 Universal measurement device for development, testing and service

The C-Series consists of smart network-capable, unventilated compact measurement devices forall-purpose measurement of physical quantities. These devices can operate either in computer-aided orautonomous mode and are lightweight, compact, and robust, and thus especially well adapted toapplications in R&D or in the testing of mechanical and und electromechanical components of machines,on board vehicles, or in monitoring tasks in installations.

The C-Series comes with either differential or isolated universal measurement amplifiers with analoganti-aliasing filters.

The universal amplifiers offer a high degree of flexibility; they are high-precision and low in noise. They aredesigned for direct connection of:

voltage- and current signals

any thermocouples and resistance thermometers

strain gauge measurement bridges with current supply and adjustment control

current-fed sensors (ICPs)

they also come with a sensor power supply and TEDS capability.

For measurements in difficult environments, where voltage conditions aren’t clearly defined, the C-Serieswith its models CS-4108 and CL-4124 offers isolated input channels. Through the use of electricallyisolated channels, signal disturbance can be prevented even in the presence of ground loops.

Depending on the model, the input channels can be sampled at up to 100kHz, and this at a bandwidth of upto 22.4kHz.

3.1.2 Different housings for different applications

To meet the wide spectrum of the C-Series’ application potential, there are three different housing varieties:the very compact CS frame for up to 16 input channels; the CL variant for up to 32 input channels; and thelarger CX frame, which has room for 32 bridge measurement channels.

3.1.3 Real-time capabilities

For real-time functionality such as mathematical calculations, limit monitoring or closed- and open-looptasks in the μs range, the C-Series comes standard equipped with the enhancement Online FAMOS.Online FAMOS comes with powerful digital signal processors (DSPs) which carry out the functions quicklyand independently of the PC. Online FAMOS enables "free" definition of one’s own real-time functions andmakes the C-Series a Personal Analyzer.

3.1.4 More than just a universal measurement amplifier

In addition to the analog inputs, all of the C-Series models also come with:

• 8 digital inputs

• 8 digital outputs

• 4 analog outputs

• 4 counter inputs for capture of RPMs, displacements etc.

• CAN-bus Interface

3.1.5 Noise and vibration analysis

The C-Series is also optimally equipped for noise and vibration analysis. The CS8008 model in particular isa device offering a large analog bandwidth and high sampling rate, as well as the possibility of directlyconnecting current-fed accelerometers and microphones. Along with simple time-domain signals, theCS8008 can also display 1/3-octave spectra.

Using the software platform imcWAVE, the measurement device is transformed into a true workstation forspecialized tasks involving noise and vibration analysis. imcWAVE’s individual optional software modulesmake order-tracking, spectral and sound power analyses possible at the click of a button.

3.1.6 Universal power measurement

For the full range of power measurements, the model CL-2108 provides the right tools. It can carry outsingle-, two-and three-phase power measurements. CL-2108 offers a convincing combination of affordableprice and high precision. An optional software package for network voltage analysis is also available.


3.1.7 Measuring with strain gauges - Structure Analysis

With five model varieties specially adapted to measuring with strain gauges, the C-Series provides the rightdevice for any structure analysis application. For performing strain gauge measurements inexpensively, themodels CS5008, CL5016 and CX5032 are available. For dynamic strain gauge measurements of thehighest quality, the models CS6004 and CL6012 are the devices of choice.

3.1.8 The C-Series in test rigs

For test rig applications in particular, it is often desirable to integrate equipment into new or existingenvironments. In conjunction with imc COM and the LabView interface, C-Series is able to meet this wish.

3.1.9 imc operating software - imcDevices

By means of the operating software imcDevices, all devices belonging to the C-Series are immediatelyready to go with all of their respective functions. Combined operation with different devices (µ-Musycs,SPARTAN, CRONOS-PL, imcC1) is also possible.

For special tasks such as system integration in test rigs, ther are comfortable interfaces for all commonprogramming languages like Visual Basic ™, Delphi ™ or LabVIEW.

3.2 What the C-Series has to offer

3.2.1 Autonomous or PC-aided

Optional color display

The C-Series devices are optimally suited for PC-less operation as compact smart measurementinstruments. a variety of different setups can be stored on the internal device hard drive and called from thedevice keyboard. If display of measured values is required, it can be provided by the external Displaydevice. If a configuration is written to the device as an Autostart configuration, measurement beginsautomatically upon activating the device.

26 imc C-series

imc C-series

3.2.2 Ethernet network capability

Die C-Series is networkable with Ethernet (TCP/IP). Multiple C-Series devices as well as older imcmeasurement systems can be joined up into a measurement network. The structure of decentralizedmeasurement networks is thus no problem at all and quickly achieved. All devices run in parallel and withcomplete synchronization of the measurement channels. Messages can be exchanged between thedevices. Of course, communication with the PC can also take place wirelessly via WLAN.

3.2.3 Real-time calculation, open- and closed-loop control

With its signal processors (DSP), and in conjunction with Online FAMOS, the C-Series is a PersonalAnalyzer. A Personal Analyzer offers not only general calculation functionality but also special calculationalgorithms such as digital filters, class-counting, order-tracking analysis and much more, as well aselectronic control unit commands and closed-loop control functions.

Without the need for programming tools, the measurement system can be expanded withapplication-specific functionality, such as data compression, calculation operations performed on wholechannels, control processes and closed-loop control functions. Complete integration of this DSPfunctionality is achieved by means of the operating software imcDevices.

3.2.4 No data loss from power outages

The C-Series comes with an internal uninterruptible power supply (UPS) and self-activation capability. In apower outage, the measurement device automatically deactivates itself. The measurement is wrapped upproperly and the data sets acquired are closed. Once the power supply has been restored, themeasurement device starts up automatically and resumes the measurement.

3.2.5 Reading measurement data from filed busses

The C-Series is equipped with a CAN-bus interface which enables the devices to read measured data andstatus information from the field bus. Measured data from the bus are processed, displayed and saved inparallel and synchronicity with conventionally measured data. The C-Series supports CAN High Speed(ISO11898) and CAN Low Speed (ISO11519).


The measured data sent via the CAN-Bus can be imported, triggered, displayed and processedsynchronously.

3.2.6 Wireless long-term monitoring and remote maintenance via modem andInternet

Maintenance of system performance, localization of sporadic errors and long-term monitoring for thepurpose of preemptive maintenance can all be substantially simplified by means of Internet-based remotemonitoring. Unmanned monitoring of vehicles, machines or plants, as well as wireless transfer ofmeasurement data all save lots of money and time.

The C-Series can be equipped with a modem which can log itself into the Internet and set up a stable andsecure GPRS online connection between the measurement device and the home PC via an Internet-basedswitching center (server).

When a signal limit is violated, the device automatically sends a report in the form of measured data, statusinformation or alarms via SMS, e-mail or FAX.

3.2.7 Global Positioning System (GPS)

With the help of a GPS system, it is additionally possible to evaluate the measured data with regard to localcircumstances and conditions.

At the nine-pin GPS socket it is possible to connect a GPS-receiver of the type GPS35LVS, which enablesabsolute synchronization to GPS time. If the GPS-mouse has reception, the measurement systemsynchronizes itself automatically. Also, if a valid DCF-77 signal is applied at the Sync-socket, the first signalwhich the hardware recognizes as valid is accepted.

As of imcDevices Version 2.6, the time counter can be selected by software. Furthermore, from this versiononward, it is possible to evaluate all GPS information which can be retrieved in the system via the processvector. By means of Online FAMOS, this information can be processed further. This requires in addition tothe imcDevices version V2.6 the GPS-receiver Garmin GPS18-5Hz.

3.2.8 Modem connection

By default, an external modem is connected via the 9-pin DSUB socket. If your system comes with abuilt-in modem, there is an RJ45 socket instead. Normal telephone connection plugs are smaller thanstandard RJ45 plugs, however they will fit without an adapter.

NoteDon’t mistake the modem socket for the Ethernet socket used to connect to a computer network.

3.2.9 TRIGGER

imc C-Series enables you to define a digital event for each measurement channel on the basis of signalthresholds, etc., and thus provide a simple method of monitoring measured quantities.

The digital events thus generated can be directly assigned to a digital output and/or can be combined incompound trigger events. In order to solve complex measurement tasks directly, up to 48 independenttriggers can be set up. Any amounts of channels can be assigned to each trigger defined.

3.2.10 TEDS

3.2.10.1 imc Plug & Measure - complex measurements as child’s play

imc Plug & Measure is based on the TEDS technology set out in IEEE 1451.4. It fulfills the vision of quickand error-free measurement even by inexperienced use.

A TEDS sensor or a conventional sensor equipped with a sensor recognition memory unit is connected tothe device. The sensor recognition contains a record of the sensor’s data and the measurement devicesettings. The C-Series reads this info and sets itself accordingly. An incorrectly measurement channel isthen recognized automatically and marked in different colors. The meaning of the colors is described inmanual imcDevices chaper 2 menu Settings Configuration Sensor tab.

3.2.10.2 Particular advantages and applications

• Quick and error-free measurement device setting

• Reduction of routine work

• Recordable measurement channel parameter recommendations (sampling rate, filter settings, etc.)

• Standardization of channel designations for particular sensors used

• Verification of calibration data and their validity

• Quick and unambiguous traceability of calibration data per ISO9000

• Monitoring of calibration intervals

• Measurement device-independent sensor administration

• overvoltage protection for 50V

3.2.10.3 Sensor administration by database

In the administration of sensor information, the user is supported by imcSensors (sensor database for theimc Plug & Measure technology).

Along with import of information from TEDS, parameters values can also be transferred from the sensordatabase by means of Drag & Drop.

Sensor information can be transferred via the measurement device software from the sensor database tothe sensor recognition and vice versa.

For more advanced sensor administration, the sensor database supports barcode reading devices.imcSensors makes the use and administration of many different sensors quick, easy and economical bythe use of TEDS and imc Plug & Measure.

imcSensors is a software expansion for imcDevices. But Plug & Measure also functions as a stand-aloneapplication. imc Sensors is designed to make a sensor's data quickly and comprehensively available.

30 imc C-series

imc C-series

It makes it possible to:

• administer sensors in a central database

• parameterize a measurement channel

• trace the calibration history

• inspect the spec sheet

In conjunction with TEDS-capable measurement amplifiers of the C-Series, imcSensors supports modernTEDS sensors in accordance with IEEE 1451.4

Especially recommendable for this purpose are the models CS-7008 and CL-7016, to which a wide varietyof sensors can be connected directly.

3.2.11 Temperature measurement

Temperatures can be measured by CS/CL-41xx and CS/CL-70xx.

Two methods are available for measuring temperature.

Measurement using a PT100 requires a constant current, e.g. of 1mA to flow through the sensor. Thetemperature-dependent resistance causes a voltage drop which is correlated to a temperature according toa characteristic curve.

In measurement using thermocouples, the temperature is determined by means of the electrochemicalseries of different alloys. The sensor produces a temperature-dependent potential difference from theterminal in the CAN connector pod. To find the absolute temperature, the temperature of the terminal pointmust be known. For the PT1000. this is measured directly in the terminal pod, and therefore a special typeof connector pod is needed.

The voltage coming from the sensor will be converted into the displayed temperature using thecharacteristic curves according temperature table IPTS-68.

Note on making settings with imcDevices

A temperature measurement is a voltage measurement whose measured values are converted to physicaltemperature values by reference to a characteristic curve. The characteristic curve is selected from theBase page of the imcDevices configuration dialog. CS/CL-70xx which enable bridge measurement, mustfirst be set to Voltage mode (DC), in order for the temperature characteristic curves to be available on theBase page.


3.2.11.1 Thermocouples as per DIN and IEC

The following standards apply for the thermocouples, in terms of their thermoelectric voltage andtolerances:

If the thermo-wires have no identifying markings, the following distinguishing characteristics can help:

Fe-CUNi: Plus-pole is magnetic

Cu-CuNi: Plus-pole is copper-colored

NiCr-Ni: Minus-pole is magnetic

PtRh-Pt: Minus-pole is softer

The color-coding of compensating leads is stipulated by DIN 43713. For components conforming to IEC584: The plus-pole is the same color as the shell; the minus-pole is white.

3.2.11.2 PT100 (RTD) - Measurement

Aside from thermocouples, RTD (PT100) units can be directly connected in 4-wire-configuration (Kelvinconnection). An additional reference current source feeds a chain of up to 4 sensors in series.

With the imc-Thermoplug, the connection terminals are already wired in such a way that this referencecurrent loop is closed "automatically".

If fewer than 4 PT100 units are connected, the current-loop must be completed by a wire jumper from the"last" RTD to "I4".

If you dispense with the "support terminals" (±I1 .. ± I4) provided in the imc-Thermoplug for 4-wireconnection, a standard terminal plug or any DSUB-15 plug can be used. The "current loop" must then beformed between "+I1" and "-I4".

4.1.1.1.1.1 Input voltage

The input voltage range can be set for a group of 8 channels to either 5V (TTL-range) or 24V. Theswitching is accomplished by means of a jumper at the ACC/DSUB-DI4-8 connector:

- If LEVEL and LCOM are jumpered, all 8 bits work with 5V and a threshold of 1.7..1.8V.

- If LEVEL is not bridged with LCOM, 24V and a threshold of 6.95 ...7.05V are valid.

Thus, an unconnected connector is set by default for 24V. This prevents 24 V from being applied to thevoltage input range of 5V.

4.1.1.1.2 Digital outputs

The digital outputs DO_01..08 provide galvanically isolated control signals with current drivingcapability whose values (states) are derived from operations performed on measurement channels usingOnline FAMOS. This makes it easily possible to define control functions.

In addition to control via Online FAMOS, it is alternatively possible to set the digital outputs interactivelyvia the user interface. Furthermore it is even possible to assign trigger values to digital outputs.

The technical specification of the digital outputs .

The pin configuration of the corresponding DSUB 15 plug ACC/DSUB-DO8 .

Important notes available levels: 5V (internal) or up to 30V with external power supply

current driving capability:HIGH: 15 - 20mA LOW: 700mA

short-circuit-proof to supply or to reference potential HCOM and LCOM

configurable as open-drain driver (e.g. as relay driver)

default-state at system power-on:HIGH (Totem-Pole mode) or high-impedance (Open-Drain mode)

The eight outputs are galvanically isolated as a group from the rest of the system and are designed asTotem-Pole drivers. The eight stages' ground references are connected and are accessible as a signalat LCOM.

HCOM represents the supply voltage of the driver stage. It is generated internally with a galvanicallyisolated 5V-source. Alternatively, an external higher supply voltage can be connected (max. +30V), whichthen determines the drivers' output level.

149


The control signal OPDRN on the D-SUB plug can be used to set the driver type for the corresponding8-bit-group: either Totem-Pole or Open-Drain :

In Totem-Pole mode, the driver delivers current in the HIGH-state. In the Open-Drain configuration,conversely, it has high impedance in the HIGH-state, in LOW-state, an internally (HCOM) or externallysupplied load (e.g. relay) is pulled down to LCOM (Low-Side Switch).With Open-Drain mode, the externalsupply driving the load, need not be connected to HCOM but only to the load.

Inductive loads (relays, motors) should be equipped with a clamp diode in parallel for shorting outswitch-off transients (anode to output, cathode to positive supply voltage).

Power-up response:

0) deactivated high-Z (high resistance)

1) power-up high-Z (high resistance)High- und LowSide switch inactive

2) first write access With “Prepare measurement” following Reset or Power-up (setting procedure): activation of the output state with the mode set by the programming pin“OPDRN”

Example: * wire jumper between programming pin “OPDRN” and LCOM (-> Totem-Pole driver type)

* Initialization (first setting procedure) with 0 (LOW)

® resulting startup sequence: High-Z à LOW, without intermediate HIGH state!!

Without further steps the default initialization state while preparing measurement is: “LOW”.If a different state is desired, the appropriate checkmark must be set in the DIO interface dialog, namelyunder:

Settings ® Input/ Output channels ® Set values of Input/ Output channels in the experiment

And not under

4.1.1.3 Incremental encoder channels

The four incremental encoder channels are for measuring time or frequency-based signals. In contrast tothe analog channels as well as to the digital inputs, the channels are not sampled at a selected, fixed rate,but instead time intervals between edges (transitions) of the digital signal are measured.

The counters used (set individually for each of the 4 channels) achieve time resolutions of up to 31ns (32Mhz); which is far beyond the abilities of sampling procedures (under comparable conditions). The"sampling rate" which the user must set is actually the rate at which the system evaluates the results of thedigital counter or the values of the quantities derived from the counters.

The pin configuration connector of the ACC/DSUB-ENC-4 . This enables all four incremental encodersto a single connector.

The technical specification of the incremental encoder .

4.1.1.3.1 Measurement quantities

The quantity to measure must be set as the input for the incremental encoder channel.The choices available:

Quantities derived from event-counting:

events

linear motion (differential)

angle (differential)

Quantities derived from time measurements:

time

frequency

velocity

rpm

pulse time (phase-difference)

The quantities derived from event-counting, Events, Linear motion and Angle are "differential"measurements: the quantity measured is the respective change of displacement or angle within the lastsampling interval. (positive or, for dual track encoders, negative also) or the newly occurred events (alwayspositive).

If, for instance, the total displacement is desired, it must be calculated by integration of the differentialmeasurements using Online FAMOS functions.

4.1.1.3.2 Time measurement conditions

The mode Time requires the definition of edge conditions, to specify the time interval to be measured(also two-signal encoder).

These conditions refer to the transitions (edges, slopes) of the digital signal:

positive edge negative edge: ( )

negative edge positive edge: ( )

positive edge positive edge: ( )

The combination

negative edge negative edge: ( ) is not allowed

For all other measurement modes (frequency, rpm's etc.), it generally isn't recommendable to define edgeconditions. For that reason, the time between two positive signal edges is evaluated, as a rule.

4.1.1.3.3 Scaling

A maximum value must be entered under Input range (max. frequency etc, depend on mode). ThisMaximum determines the scaling factor of the computational processing and amounts to the range which isrepresented by the available numerical format of 16bits. Depending on the measurement mode (quantity tobe measured), it is to be declared as an input range's unit or in terms of a corresponding max. pulse rate.

A maximum value must be entered under Input range (max. frequency etc, depend on mode). ThisMaximum determines the scaling factor of the computational processing and amounts to the range which isrepresented by the available numerical format of 16bits. Depending on the measurement mode (quantity tobe measured), it is to be declared as an input range's unit or in terms of a corresponding max. pulse rate.

In the interest of maximizing the measurement resolution it is recommended to set this value accordingly.

The Scaling is a sensor specification which states the relation between the pulse rate of the sensor and it'scorresponding physical units (sensitivity). This is also the place to enter a conversion factor for the sensoralong with any physical quantity desired, for instance, to translate the revolutions of a flow gauge to acorresponding volume.

The table below summarizes the various measurement types' units;the bold, cursive letters denote the (fixed) primary quantity, followed by its (editable) default physical unit:

Velocity Pulse / m m / s m / s

RPM Pulse / U U / min U / min

Event Pulse / Pulse 1 Pulse Hz

Frequency Hz / Hz Hz Hz

Pulse time 1 1 s

4.1.1.3.4 Sensor types, synchronization

Index signal denotes the synchronization signal SYNC which is globally available to all four channels incommon. If its function Encoder w/o zero impulse is not activated, the following conditions apply: After thestart of a measurement the counters remain inactive until the first positive slope arrives from SYNC. Thisarrangement is independent of the release-status of the Start-trigger condition.

The index signal is armed for each measurement!

If a sensor without an index track (Reset signal) is used, Encoder w/o zero impulse must be selected,otherwise the counters will remain in reset-state and will never be started because the enablingstart-impulse will never occur!!

Incremental encoder sensors often have an index track (index signal, zero marker pulse) which emits asynchronization-signal once per revolution. The SYNC-input is differential and set by the comparatorsettings. Its bandwidth is limited to 20kHz by a permanently low-pass filter. The input is located onACC/DSUB-ENC4 Pins 6 and 13. If the input remains open, an (inactive) HIGH-state will set in.

The measurement types Linear Motion, Angle, RPM and Velocity are especially well adapted for directconnection to incremental encoder-sensors. These consist of a rotating disk with fine gradation inconjunction with optical scanning and possibly also with electric signal conditioning.

One differentiates between single track and dual track encoders. Dual track encoders (quadratureencoders) emit two signals offset by 90° of phase, the tracks A and B (C and D). By evaluating the phaseinformation between the A and B-track, the direction of turning can be determined. If the correspondingencoder type is selected, this functionality is supported.

The actual time or frequency information, however, is derived exclusively from the A(C) -track!


The measurement types Event, Frequency, and Time always are measured by one-track encoders, sincein these cases no evaluation of direction or sign would make any sense. The sensor must simply beconnected to the terminal for Track A (C).

Since many signal encoders require a supply voltage, +5V are provided at the connector socket for thispurpose (max. 300mA). The reference potential for this voltage, in other words the supply-groundconnection for the sensor, is CHASSIS.

4.1.1.3.5 Comparator conditioning

The incremental encoder channels' special properties make special demands on the signal quality: Thevery high time-resolution of the detector or counter means that even extremely short impulses whichsampling measurement procedures (as at the digital inputs) would miss are captured and evaluated.Therefore the digital signals must have clean edges in order not to result in distorted measurements.Missed pulses or bounces could otherwise lead to drop-outs in the time measurements, or enormous"peaks" in the rpm-measurements.

Simple sensors such as those based on induction or photosensitive relays often emit only unconditionedanalog signals which must be evaluated in terms of a threshold value condition. Furthermore long cables,ground loops or interference, can make the processing of even conditioned encoder signals (such asTTL-levels) difficult. The device, however, can counteract this using its special three-step conditioning unit.

To begin with, a high-impedance differential amplifier (10V range, 100k) enables reliablemeasurement from a sensor even along a long cable, as well as effective suppression of common modeinterference and ground loops. A (configurable) filter (in preparation) at the next stage offers additionalsuppression of interference, adapted to the measurement set-up. Finally, a comparator with configurablethreshold and hysteresis acts as a digital detector. The (configurable) hysteresis is an extra tool forsuppressing noise:

VREF VHYST

INC(digital)

IN(analog)

IN > VREF+VHYST/2 IN < VREF-VHYST/2

If the analog signal exceeds the threshold VREF + VHYST/2. the digital signal changes its state ( : 0 1)and at the same time reduces the threshold which must be crossed in order to change the state back to 0by the amount VHYST (new threshold: VREF - VHYST/2). The magnitude of the hysteresis thereforerepresents the maximum level of noise and interference that would not cause a spurious transition.

The threshold VREF is set to 1.5V, the hysteresis VHYST is 0.5V.State transitions are therefore detected at the signal amplitudes:

1.75V ( 0 1 ) and1.25V ( 1 0 ).

In future device versions, the threshold and hysteresis will be globally adjustable for all four channels withinthe range:

VREF = 10V VHYST = +100mV .. +4V

Corner frequencies of the (2-pole) low-pass filter will be jointly configurable for both of a channel's tracks tothe values:

Low-pass filter: 20kHz, 2kHz, 200Hz

Dual track encoders (quadrature encoders) emit two signals offset by 90° of phase, the tracks A and B. Byevaluating the phase information between the A and B-track, the direction of turning can be determined. Ifthe corresponding encoder type is selected, this functionality is supported. The actual time or frequencyinformation, however, is derived exclusively from the A-track!

Like the other channels, the Index-channel is fully conditioned. If its function is activated, it can take effecton all four channels. At the imc terminal plug the pin is labeled ±INDEX.

4.1.1.3.7 Channel assignment

The connector used is the ACC/DSUB-ENC-4. It enables all four incremental counters to be connected atthe same terminal.

As a prerequisite for the input differential amplifier to find the correct working point, the sensor must beground referenced, i.e. it must have low resistance to ground (GND, CHASSIS, PE). This is not to beconfused with the sensor’s common mode voltage, which may be up to +25V/-12V (even for the –IN input!).It also does not matter that a differential measurement is configured for the high-impedance differentialinput. If this electrical connection to the system ground (CHASSIS) does not exist initially because thesensor is electrically isolated, then such a connection must be set up, for instance in the form of a wirejumper between the sensor’s GND and POWER_GND contacts!

The 5V (max. 100mA, 300mA upon request) supply voltage which the module provides at the terminals+5V and GND can be used to power the sensors. If more voltage or supply power is needed, the sensormust be supplied externally, which means that it is absolutely necessary to ensure that this supply voltageis referenced to system ground!

Each of the 4 incremental encoder channels has an A and a B-track (C and D) for connecting a two-signalencoder. If a one-signal encoder is used, it must be connected to the X-track and the positive Y-track mustbe shorted with the negative Y-track. If the index-input isn't used, the positive index channel must beshorted with the negative index-channel.

Commercially available rotary encoders are often equipped with differential line drivers, for instance as perthe EIA-standard RS422. These deliver a complementary (inverse) TTL-level signal for each track. Thesensor's data are evaluated differentially between the complementary outputs. The threshold to select is0V, since the differential evaluation results in a bipolar zero-symmetric signal: 3.8...5V (HIGH) or –3.8...-5V(LOW).

4.1.2.1 ACC/DSUB-ICP ICP-Expansion plug for voltage channels

4.1.2.1.1 ICP-Sensors

The ICP-channels are specially designed for the use of current-fed sensors in 2-wire-configuration.This sensor type is fed with a constant current of typically 4mA and delivers a voltage-signal consisting of aDC-component (typ. +12V) superimposed with an AC-signal (max. 5V).

ICP-sensors are typically employed in vibration and solid-borne sound measurements and are offered byvarious manufacturers as solid-borne sound microphones or accelerometers under different(trademarked) product names, such as:

PCB: ICP-Sensor, KISTLER: Piezotron-Sensor, Brüel&Kjaer: DeltaTron-Sensor.

The commonly used name ICP (Integrated Circuit Piezoelectric) is actually a registered trademark of theAmerican manufacturer "PCB Piecotronics".

The technical specification of the module ACC/DSUB-ICP4 .

4.1.2.1.2 Feed current

The exact magnitude of the supply current is irrelevant for the measurement's precision. Values of 2mAtend to be adequate. Only in the case of very high bandwidth and amplitude signals in conjunction with verylong cables, supply currents may be a concern, as considerable currents are need to dynamically chargethe capacitive load of the cable.

dynam. current headroom: I = 2mAcable capacity (typ. coax-cable): C = l * 100pF/mmax. signal slew rate (full-power): dU/dt = 5V * 2*PI*25kHz

max. cable length: l_max = 2mA / (100pF/m * 5V * 2*PI*25kHz) = 25m

Up to a max. cable length of 25m, no limitations are to be expected as long as the above conditions arefulfilled.

4.1.2.1.3 ICP-Expansion plug

As a special accessory for voltage channels, an ICP expansion plug is available. This can be used todirectly connect current-fed ICP-sensors also at voltage channels.

4-channel models (ACC /DSUB-ICP4) are available for the following devices:C-12xx, C-10xx, C-41xx

2- channel models (ACC /DSUB-ICP2) are available for the following devices:

C-70xx, C-50xx, C-60xxThis (active) expansion plug having the same dimensions as the imc DSUB-plug, comes with additionalconditioning equipment built into its housing and having the following features:

individual current sources for the current-fed ICP-sensors

per source: 4.2mA (typ.), voltage swing: max. 25V

differential AC-coupling to block the signal's DC-component (approx. +12V) typical with ICP.

each channel can be switched to current-fed ICP measurement (AC-coupled) or DC-coupled voltagemeasurement.

Switch position ICP:

The AC-coupling is already provided by the ICP-plug, the voltage channel is DC-coupled.

The input range must be adapted to the signal's AC-component, it can be adjusted within the rangebetween 5V ... 250mV

The combination of the built-in coupling capacitor (2 x 220nF corresponding to 110nF diff.) with theimpedance of the ICP-plug (2M diff.) and the input impedance constitutes a high-pass filter. Whenconnecting the plug or sensor, be aware of the transients experienced by this high-pass filter, causedby the sensor's DC-offset (typ. +12V). It is necessary to wait until this phenomenon decays and themeasured signal is offset-free!

When the ICP-expansion plug is used, a considerable offset can occur (in spite of AC-coupling), whichcan be traced to the (DC-) input currents in conjunction with the voltage amplifier's DC input impedance.This remainder, too, can be compensated by high-pass filtering with Online FAMOS.(Direct high-pass filtering for voltage channels is in preparation).

Switch position Volt:

The voltage channel is DC-coupled, the current source de-coupled.

The voltage channel's input impedance is reduced by parallel connection with the ICP-plug'simpedance.

We recommend using multicore, shielded cable, where the shielding (at the plug) is connected to theplug "CHASSIS", or can be connected to the pull-relief brace in the plug.

4.1.2.2 ACC/DSUB-ICP2-BNC, ACC/DSUB-ICP2-MICRODOT

This is a 2-channel pre-amp in the form of an imc clamp terminal, which enables two sensors having ICP-output to be connected via BNC interconnections. To the available coupling types for channels to which it isconnected, it offers the additional entry “AC with current supply”, which makes direct connection of ICP™ -,

DeltaTron®-, or PiezoTron®

-sensors possible. The connector ensures a 4mA current supply.

Once the ICP2-BNC terminal is connected, the information on the TEDS-capable sensors used must beimported. Otherwise, this error message will appear upon performing preparation:

"All channels connected to the imc clamp terminal ACC/DSUB-ICP2-BNC requires inputcoupling AC with current feed or DC! Error number 6329"

Channels at which an ICP2-BNC terminal is connected but not any TEDS-capable sensor must be set toDC, in order to be able to successfully prepare the measurement.

However, if the opposite case occurs: “AC with current feed” is set but no ICP terminal is connected at thecorresponding channel, the following error message provides notification of this:

"The required imc clamp terminal ACC/DSUB-ICP is not connected! Error number: 6334"

In this case, an appropriate terminal must be connected or the coupling type must be corrected byimporting the sensor’s info (if no sensor info is found, the typical coupling types for that amplifier aredisplayed again).

4.1.2.4 imc Display

The optional display screen enables interaction between the user and a running measurement process byposting read-outs of system states and allowing parameter adjustments via the membrane touch panel.

If the measurement device is prepared for opening a particular configuration upon being activated, it’spossible to carry out the measurement without any PC. The display serves as a convenient status indicatorand can replace or supplement imcDevices for process control purposes. It works even where no PC ordisplay unit normally could, for example at temperatures of -20°C or +70°C.

The Display can be connected or disconnected at any time without disturbing a running measurement. Thismakes it possible, for instance, to check the status of multiple running devices in succession.

The Display’s interaction with the measurement device is handled by means of virtual Display variables orbits, which can either be evaluated for the purpose of status indication or set in order to affect themeasurement process.

A variety of different models of the Display are available:

- Alphanumeric Displays – Hand-held terminals and built-in displays

4.1.2.5 GPS

At the nine-pin GPS socket it is possible to connect a GPS-receiver of the type Garmin GPS35LVS,GPS18LVC, GPS18LVC-5Hz etc. which enables absolute synchronization to GPS time. If the GPS-mousehas reception, the measurement system synchronizes itself automatically. Also, if a valid DCF-77 signal isapplied at the Sync-socket, the first signal which the hardware recognizes as valid is accepted.

As of imcDevices Version 2.6, the time counter DCF77 or GPS can be selected by software. Furthermore,from this version onward, it is possible to evaluate all GPS information which can be retrieved in the systemvia the process vector. By means of Online FAMOS, this information can be processed further.

4.1.2.6 LEDs and Beeper

6 Status-lamps (LEDs, on the device front panel) and a beeper are provided as additional visual andacoustic "output channels". They can be used just as standard output channels in Online FAMOS byassigning them the binary values "0" / "1" or functions taking the Boolean value range.

Interactive setting and Bit-window display for these output channels is neither especially useful norsupported.

It is not possible to deactivate the beeper by software.

4.1.2.7 Modem connection

By default, an external modem is connected via the 9-pin DSUB socket. If your system comes with abuilt-in modem, there is an RJ45 socket instead. Normal telephone connection plugs are smaller thanstandard RJ45 plugs, however they will fit without an adapter.

Pin configuration of the 9 pin DSUB socket .

NoteDon’t mistake the modem socket for the Ethernet socket used to connect to a computer network.

4.1.2.8 SYNC

For a synchronized measurement use the SYNC terminal. That connector has to be connected with otherimc devices or a DCF77 antenna.

Note

When using multiple devices connected via the Sync terminal for synchronization purposes, ensure thatall devices are the same voltage level. Any potential differences among devices may have to be evenedout using an additional line having adequate cross section.

Alternatively it is possible to isolate the devices by using the module ISOSYNC.

4.1.2.9 Filter-Einstellungen

4.1.2.9.1 Theoretischer Hintergrund

Der Filter-Einstellung kommt bei einem abtastenden Mess-System besondere Bedeutung zu: Aus derTheorie digitaler Signalverarbeitung und des Abtasttheorems (Shannon, Nyquist) geht hervor, dass beieinem abtastenden System eine Bandbegrenzung des Signals vorhanden sein muss. Diese stellt sicher,dass das Signal ab der halben Abtastfrequenz (Nyquist-Frequenz) keine nennenswerten spektraleSignalanteile mehr beinhaltet. Andernfalls führt dies zu Aliasing - Fehlern, die auch durch nachträglicheFilterung nicht mehr zu beseitigen sind.

SPARTAN-Ux(-CAN) stellt ein abtastendes System dar, bei dem die im Konfigurationsmenü einzustellendeAbtastzeit (bzw. Frequenz) dieser Bedingung unterworfen ist. Die auswählbare Tiefpass-Filterfrequenz istdabei bestimmend für die Bandbegrenzung des mit dieser Rate abzutastenden Eingangssignals.

Die Einstellung AAF für die Filtereinstellung steht für Automatisches Antialiasing Filter. Sie nimmt eineautomatische Wahl der Filterfrequenz vor, angepasst an die gewählte Abtastrate. Die zugrundeliegendeRegel dabei ist:

AAF-Filterfrequenz (-80dB) = Abtastfrequenz * 0,6 = Nyquistfrequenz * 1,2

AAF-Filterfrequenz (-0,1dB) = Abtastfrequenz * 0,4 = Nyquistfrequenz * 0,8

4.1.2.9.2 Allgemeines Filter-Konzept

Die C-Serie verwendet eine zweistufige Systemarchitektur, bei dem die analogen Signale mit einer festenprimären Abtastrate abgetastet werden (analog-digital Wandlung mit Sigma-Delta ADCs). Hierbeivermeidet ein festes analoges Tiefpassfilter Aliasing-Fehler. Der Betrag dieser primären Abtastrate ist nichtnach außen hin sichtbar, hängt vom Kanaltyp ab und ist in der Regel größer oder gleich der in derEinstelloberfläche wählbaren Abtastrate. Das einstellbare Filter ist als digitales Filter realisiert, welches denVorteil eines exakten Betrags- und Phasenverlaufs hat. Dies ist insbesondere für den Gleichlauf (Matching)von miteinander verrechneten Kanälen von großer Bedeutung.

Werden in der System-Konfiguration langsamere Datenraten (f_sample) eingestellt, so gewährleistendigitale Anti-Aliasing Filter (Tiefpass-Filter) die Einhaltung der Bedingungen des Abtast-Theorems. DreiFälle können dabei unterschieden werden:

4.1.2.9.3 Implementierten Filter

Filter-Einstellung „Filter-Typ: ohne“:

Nur das (analoge) auf die primäre Datenrate abgestimmte Anti-Aliasing-Filter ist wirksam, neben einernachgeschalteten digitalen Frequenzgang-Korrektur, die für einen steileren Frequenzgang sorgt.Diese Einstellung kann sinnvoll sein, wenn maximale Bandbreitenreserven genutzt werden sollen undgleichzeitig einschränkende Annahmen über die spektrale Verteilung des Messsignals gemacht werdenkönnen, die einen Verzicht auf vollständige Filterung rechtfertigen.

Filter-Einstellung „Filter-Typ: AAF“:

Die (digitalen) Anti-Aliasing-Filter werden als elliptische Cauer-Filter ausgeführt. Deren „scharfe“ Kennlinieim Frequenzbereich ermöglicht es, die Eckfrequenzen erheblich näher an die Abtast- bzw.Nyquist-Frequenz heranzuführen, ohne Kompromisse zwischen Bandbreite und Aliasing-Freiheiteinzugehen.

Die automatische Wahl der Eckfrequenz in der Einstellung „AAF“ basiert auf folgenden Kriterien:

Im Durchlassbereich („pass band“) ist eine maximale (AC-) Verstärkungs-Unsicherheit von 0.006% = -0.005dB zulässig. Das pass band ist definiert durch die Eckfrequenz, bei der dieser Wertunterschritten wird.

Der Sperrbereich („stop band“) ist gekennzeichnet durch eine Dämpfung von mindestens –80 dB.Diese Dämpfung wird auch für 16-Bit Systeme als ausreichend angesehen, da diskrete Störfrequenzennie 100% Amplitude erreichen können: der nutzbare Messbereich wird im wesentlichen durch dasNutzsignal ausgefüllt. Andernfalls müsste ohnehin ein größerer Bereich gewählt werden um

54 imc C-series

imc C-series

Übersteuerung zu vermeiden.

Der Übergangsbereich („transition band“) liegt typischerweise symmetrisch um die Nyquist-Frequenzherum. Damit ist gewährleistet, dass die ins pass band zurückgespiegelten Aliasing-Anteile aus demstop band um ausreichende (mind.) –80dB unterdrückt sind. Rest-Anteile aus dem Frequenzbereichzwischen Nyquist-Frequenz und stop band Grenze spiegeln lediglich zurück in den Bereich außerhalbdes pass band (pass band bis Nyquist) dessen Signalgehalt als nicht relevant definiert ist.

Die genannten Kriterien sind mit den verwendeten Cauer-Filter durch folgende Konfigurations-Regelerfüllt:

Filter-Einstellung „Filter-Typ: AAF“:

fg_AAF (-0.1dB) = 0.4 * f_sample;

Charakteristik: Cauer Filter-Ordnung: 8-pol

Filter-Einstellung „Filter-Typ: Tiefpass“:

Es kann manuell eine Tiefpassfrequenz gewählt werden, die den konkreten Anforderungen derApplikation gerecht wird. Insbesondere kann eine Eckfrequenz deutlich unterhalb der Nyquist-Frequenzeingestellt werden, die in jedem Fall ein Aliasing garantiert ausschließt, natürlich unter „Opferung“entsprechender Bandbreite-Reserven.

mit fg_AAF (3dB) = f_sample / 4 Dämpfung bei Nyquist Frequenz: 1/64 = -36 dB



Charakteristik: Butterworth, Filter-Ordnung: 8-pol

In jedem Fall ist die Einstellung AAF keine Garantie für Aliasing-freies Messen: Die Anforderungen an dasFilter sind im konkreten Anwendungsfall zu überprüfen und bei stark gestörten Signalen anzupassen. Dadie einstellbaren Abtast- und Filterfrequenzen jeweils in 1 – 2 – 5 Schritten gestuft sind, ist stets entweder 1

/4 oder 1/5 der Abtastrate als Filter einstellbar.

Weitere mögliche Filtereinstellungen sind Bandpass und Hochpass jeweils 4.Ordnung.


4.1.2.10 DSUB-Q2 charging amplifier

Charging amplifier in DSUB connector

The charging amplifier accessory DSUB-Q2 serves as an adapter for a piezo-electric sensor having acharge output to the voltage measurement inputs of the CRPL device family. It contains two miniaturecharge amplifiers which convert charge to voltage. They can perform both quasi-static and dynamicmeasurements, and can be used to measure force, velocity and acceleration directly or indirectly.

charging amplifier DSUB-Q2

The two-channel pre-amp takes the form of an imc plug which enables two charge sensors to beconnected via BNC. It adds the options “DC charge” and “AC charge” to the list of coupling types availablefor the channels to which it is connected. Since only charges can be measured at the channels concernedas long as the terminal is connected, the other coupling types are not available.

Once the DSUB-Q2 terminal is connected, the channels used are configured by importing the sensor

information . Otherwise, this error message appears during the preparation process:

"The required imc plug with charging amplifier DSUB-Q2 is not connected! Error number:6333"

Now the channels are set to chargecoupling. All other couplings such ascurrent measurement, bridgemeasurement etc. are now no longeravailable.

imcDevices>amplifier tab: DSUB-Q2 settings with UNI-8

NOTE

The charge amplifier itself is not TEDS-capable, so it is not possible to import sensor information from theconnected charge sensors. For this reason, the button “Import sensor data from sensor and set channel”causes the function “Import connector data and set channel” to be performed in this case.

However, if the opposite case occurs, namely that charge coupling is set but no charge amplifier isconnected to the corresponding channel, the following error message provides notification of this:

"The required imc plug charging amplifier DSUB-Q2 is not connected! Error number: 6333"

CL-1032

4.2.2 Hardware configuration

The devices come with the following analog measurement channels:

voltage current current-fed sensors e.g. ICP (optional)

4.2.3 Signal conditioning and circuitry

The devices come with 16 (CS) or 32 (CL) differential, non-isolated input channels which can be used formeasuring voltage. In addition, current measurement by means of a shunt plug and the use of anICP-expansion plug are provided for.

The module is built as a "scanner" which enables the maximum aggregate sampling rate of 320kHz to bedistributed among the amount of activated channels (up to 16). The maximum sampling rate for a singlechannel can extend up to 20kHz.

The channels each come with 5th order ("analog", fixed-configuration) anti-aliasing filters, whose cutofffrequency is 6.8kHz. This means that for a channel sampled at 20kHz, nearly aliasing-free measurement inthe sense of the Sampling Theorem is ensured.

116


For low channel sampling rates (esp. when many channels are active), appropriately adapted (digital)low-pass filter are implemented. This procedure then no longer stringently adheres to the condition for theSampling Theorem, since the cutoff frequency of the "primary" analog filter (6.8kHz) is not adapted to thelower channel sampling rate; however, the properties of this affordable module are perfectly adequate for anumber of applications.

Input ranges: 250mV, 1V, 2.5V, 10V

Analog bandwidth: 6.8kHz (-3dB).

Maximum aggregate sampling rate: 320kHz

Impedance: 20M (differential)

4.2.3.1 Voltage measurement

Voltage ranges: 250mV, 1V, 2.5V, 10V

The input impedance is 10M referenced to system ground or 20M differential. The inputs areDC-coupled. The corresponding connection terminal is designated ACC/DSUB-U4

4.2.3.2 Current measurement

Current ranges: 5mA, 20mA, 50mA

For current measurements, a special plug with a built-in shunt (50) is needed (order #: ACC/DSUB-I4).Configuration is carried out in the voltage mode, but an appropriate scaling factor is entered which allowsdirect display of current values (20mA/V = 1/50).

For current measurement with the special shunt-plugs ACC/DSUB-I4, input ranging only up to max. ±50mA (corresponding to 2V or 2.5V voltage ranges) are permitted due to the measurement shunt'slimited power dissipation in the case of static long-term loading.

4.2.4 Current-fed sensors

For measurement of current-fed sensors, e.g. ICPs, the special connector ACC/DSUB-ICP2 is required.

4.2.4.1 External +5V supply voltage

At the DSUB-15 connector plugs, there is a 5V supply voltage available for external sensors or for theICP-expansion plug. This source is not isolated; its reference potential is identical to the overall system'sground reference.

The +5V supply outputs are electronically protected internally against short-circuiting and can each beloaded up to max. 160mA (short-circuit limiting: 200mA). The sensor's reference potential, in other wordsits supply-ground connection is the terminal "GND".

For measurement ofcurrent, the ACC/DSUB-I4, which comes with 50 shunts, must be used. In addition, the use of anICP-expansion plug ACC/DSUB-ICP4 is possible.

Voltage: 50 V... 5 mV

In the voltage ranges 50 V and 20 V, a voltage divider is in operation; the resulting input impedance is 1M. In the voltage ranges 10 V to 5mV, by contrast, the input impedance is 20M. When the device isdeactivated, it drops to about 1 M.

The input configuration is differential and DC-coupled.

The voltage source itself already is referenced to the device's ground. The voltage source is at the samepotential as the device ground.

-in

GND

+- U

e

Example: The unit is grounded. Thus, the input GND is at ground potential. If the voltage source itself isalso grounded, it is referenced to the device ground. It isn't any problem if, as it may be, the groundpotential at the voltage source deviates from the ground potential of the device itself by a few degrees. Themaximum permitted common mode voltage must not be exceeded.

Important: In this case, the negative signal input -IN may not be connected to the ground contact GND inthe device. Otherwise, a ground loop would result, through which interference could be coupled in.

In this case, a true differential (but not isolated!) measurement is performed.

4.3.3.1.2 Case 2: Voltage source without ground reference

The voltage source itself has no reference to unit’s ground, but instead, its potential floats freely vis-à-visthe device ground. If a ground reference cannot be established, it's also possible to connect the negativesignal input –IN to the ground contact GND.

If the source can't be broughtto that potential level (because it turns out to be at fixed potential after all), there is a risk of permanentdamage to the amplifier. If IN and GND are connected, a single end measurement is performed. This isn'ta problem unless a ground reference already existed.

With voltage measurement, it's possible to tare a zero offset to restore correct zero. For this purpose,select the menu item Settings _ Amplifiers (balance etc.)…, and on the screen's index card Common,under Balancing, select the option Tare for the desired channel. The input range correspondingly isreduced by the amount of the zero adjustment.

current probes/ low voltages direct support for the use ofRogowski coils


4 differential analog inputsThe high voltage amplifier consists of one two-channel master module and one two-channel attachmentmodule which is configured for measurement of either voltage or current probe signals. Thus, a singleamplifier can acquire either four voltage signals or two voltage and current probe channels each.

4.4.3.1 High-voltage channels

The high-voltage channels are each equipped with an isolated amplifier. They enable direct measurementof voltages of up to ±600V (peak values), in accordance with the protection class CAT II. The utilization isdetermined for each target system, and may not reach the maximum in some cases – refer to the technicaldata.

4.4.3.3.1 Voltages

For voltage measurements of up to 1000V (peak), safety banana jacks are provided.

The maximum permitted voltage to ground depends on the measurement site. See Chapter T tolearn the measurement category.

Only use connectors which are protected on all sides against touch.

All the inputs are individually isolated.

The voltage channels are each equipped with isolated amplifiers. They enable direct measurement ofvoltages up to ± 1000 V (this values decreases the higher the measurement category is see thetechnical data).

4.4.3.3.2 Currents

Current measurement is achieved contact-freeCC by means of current probes. To connect thesetransducers, three-pin Phoenix sockets are provided. Only current probes fitted by imc with specialterminals can be connected. Connection resembles the illustrations below.

Current probe MN71 Current transducer AmpFLEX A100

The current probes recommended by imc cover the range for low currents (< 10A) and for medium to highcurrents (5...10kA). With probes having multiple input ranges, the input range set on the probe must alsobe correctly set by hand in the user’s interface.Both the amplitude- and phase response of the currentprobes provided by imc are measured prior to delivery and recorded in a TEDS. The amplifier is able toread this information and to correct the signal accordingly.

Notes

If the current input range set in the user’s interface doesn’t match the probe’s, the current signal isscaled incorrectly. However, the device’s electronics are not in danger of damage.

Use only current probes provided by imc, or have your own current probes modified by our customerservice. Only then can error-free functioning be assured. imc will not accept responsibility fordisturbances or damage sustained by the device if unauthorized probes are used.

Whenever you connect a new current probe, read its TEDS information. This is the only way to ensurethat phase-independent quantities (e.g. power) are determined correctly. The TEDS data are recordedalong with the experiment and therefore need not be imported each time the same equipment isactivated.

4.4.3.4 Using transducers

Compensation of systematic transducer conversion errors isn’t possible, since these errors aren’t known. Ifthe transducer’s conversion uncertainty is specified, it often only pertains to the technical frequencies, sothat the error estimation for higher harmonics is difficult.

Note

The transducers’ amplitudes and angle errors influence the measurement results, which especially affectsthe measurement of power.

4.4.3.6.1 Notes on the measurement setup

Measurement lines must be kept away from unshielded conductors, sharp edges, electromagnetic fieldsand other adverse environmental factors.

Measurement line for the voltage: The measurement line’s connection to the measurement objectmust be designed for the maximum occurring voltage. Before conducting the measurement, check theline leading to it in order to prevent the occurrence of dangerous touch voltages and short circuits. Theuse of flexible terminals makes special care necessary. It must be checked whether the mechanicalconnection is secure and what would happen if it is accidentally disconnected. For increased reliability,the lines should be secured at the measurement location. The fuse’s breaking capacity must correspondto the expected error current at the measurement location.

Measurement line for the current: The current probes must be connected in a mechanically securemanner. The aim should be to orient it orthogonally to the current rail or lead. This applies especially tocurrent measurement coils operating according to the Rogowski principle.

Measurement device: The device must be placed in such a way that no terminals can be accidentallydisconnected.

4.5.5 Voltage measurement

Voltage: ±50V... ±5mV

In the voltage ranges 50 V and 20 V, a voltage divider is in operation; the resulting input impedance is 1M in DC mode and 0.67M in AC mode. In the voltage ranges ≤10 V, by contrast, the input impedanceis 20M in DC and 1.82M in AC mode. When the device is deactivated, it drops to about 1 M.

With the AC coupled ICP-measurement the DC voltage is suppressed by a high pass filter of 0.37Hz for allranges ≤ 10V. For the ranges ≥ 20V the low pass cut-off frequency is 1Hz. The input configuration isdifferential.

Example: The measurement system is grounded. Thus, the input GND is at ground potential. If thevoltage source itself is also grounded, it is referenced to the device ground. It isn't any problem if, asit may be, the ground potential at the voltage source deviates from the ground potential of the deviceitself by a few degrees. The maximum permitted common mode voltage must not be exceeded.

Important: In this case, the negative signal input -IN may not be connected to the ground contactGND in the device. Otherwise, a ground loop would result, through which interference could becoupled in.

In this case, a true differential (but not isolated!) measurement is performed.

4.5.5.2 Case 2: Voltage source without ground reference

The voltage source itself has no referenceto the device's ground, but instead, itspotential floats freely compared to thedevice ground. If a ground referencecannot be established, it's also possible toconnect the negative signal input –IN to theground contact GND.

If IN and GND are connected, a single endmeasurement is performed. This isn't a problem unless a ground reference already existed.

4.5.6 Bandwidth

The channels' max. sampling rate is 100kSamples/s (10µs sampling interval). The analog bandwidth(without digital low-pass filtering) is 14kHz (-3dB). In AC mode the lower cut off frequency is 0.37Hz for allranges ≤ 10V, else 1Hz.

CS-4108 and CL-4124 are 8- and 24-channel universal measurement devices, respectively, with samplingrates of up to 50kHz per channel. They are specially designed for measurement tasks in environments withunclear voltage fields such as test rigs or large-scale machinery. The input channels are electricallyisolated, differential and equipped with per-channel signal conditioning including filters.

current-fed sensors e.g. ICP (optional) thermocouples

Each of the isolated voltage channels has its own isolated amplifier, operated in the voltage mode.

Along with voltage measurement, current measurement via a shunt plug and temperature measurementare all provided for. It is also possible to use the ICP extension plug with the ISO2-8, but than theisolation properties are not effective anymore.

The analog bandwidth (without low-pass filtering) of the isolated voltage channels is 8kHz.

General remarks on isolated channelsWhen using an isolated channel (with or without supply), one should make sure the common modepotential is "defined", one way or another: Using an isolated channel on an isolated signal source usuallydoes not make sense. The very high common mode input impedance of this isolated configuration (> 1G)will easily pick up enormous common mode noise as well as possibly letting the common mode potentialdrift to high DC-level. These high levels of common-mode noise will not be completely rejected by theamplifier's common-mode (isolation-mode) rejection.

So, as a general rule: isolated amps should be used in environments where the common-mode level is highbut "well defined" in terms of a low (DC-) impedance towards (non-isolated) system ground (CHASSIS).

In other words: isolated amps are used in environments where the common mode levels and noise arealready inherent in the process and not just accidental results of the equipment's isolation.

If, in turn, the signal source itself is isolated, it can be forced to a common-mode potential, which is thepotential of the measurement equipment. This is the case with a microphone: the non-isolated powersupply will force the common mode potential of the microphone and amp-input to system ground instead ofleaving it floating, which would make it susceptible to all kinds of noise and disturbance.

Voltage: 60V ... 50mV in 11 different ranges

An internal pre-divider is in effect in the voltage ranges 50V to 5V. In this case, the differential inputimpedance is 1M, in all other ranges 10M. If the device is de-activated, the impedance is always 1M.

The inputs are DC-coupled. The differential response is achieved by means of the isolated circuiting.

For current measurement with the special shunt-plugs ACC/DSUB-I4, inputs ranging only up to max. ±50mA (corresponding to 2V or 2.5V voltage ranges) are permitted due to the measurement shunt'slimited power dissipation in the case of static long-term loading.

The isolated voltage channels are also provided with a 5V supply voltage at the DSUB-15 connectorplugs, for external sensors or ICP-extension plug. This source is not isolated; its reference potential isidentical to the non-isolated reference ground of the overall system.

These +5V supply outputs are each electronically protected inside from short-circuiting, against up to 160mA (limit of short circuit protection: 280mA). The reference potential, in other words the supply's groundconnection for the sensor, is the terminal GND.

4.6.3.4 Temperature-channels

Transducers which translate the physical measurement quantity into their own current consumption andwhich allow variable supply voltages can be configured in a two-wire circuit. In this case, the device has itsown power supply and measures the current signal.

In the settings dialog on the index card Universal amplifiers/ General, a supply voltage is set for thesensors, usually 24V. The channels must be configured for Current measurement.

The sensor is supplied with power via Terminals C and G.

The signal is measured by the unit between A and D. For this reason, a wire jumper must be positionedbetween Pins A and G inside the connector pod.

NoteThere is a voltage drop across the resistances of the leadwires and the internal measuring resistance of 120W which is proportional to the amperage. This lost voltage is no longer available for the supply of thetransducer (2.4V = 120W * 20mA). For this reason, you must ensure that the resulting supply voltage issufficient. It may be necessary to select a leadwire with a large enough cross-section.


4.7.3.3 Bridge measurement

Measurement of measurement bridges such as strain gauges.

The measurement channels have an adjustable DC voltage source which supplies the measurementbridges. The supply voltage for all eight inputs is set in common. The bridge supply is asymmetric, e.g., fora bridge voltage setting of VB = 5V, Pin C is at +VB = 5V and Pin D at -VB = 0V. The terminal–VB issimultaneously the device's ground reference.

Depending on the supply set, the following input ranges are available:

Bridge measurement [V] Input ranges [mV/V]

10 1000 ... 0.5

5 1000 ... 0.5

Fundamentally, the following holds:

For equal physical modulation of the sensor, the higher the selected bridge supply is, the higher are theabsolute voltage signals the sensor emits and thus the measurement's signal-to-noise ratio and driftquality. The limits for this are set by the maximum available current from the source and by the dissipationin the sensor (temperature drift!) and in the device (power consumption!) For typical measurements with strain gauges, the ranges 5 mV/V ... 1mV/V are particularly relevant. There is a maximum voltage which the Potentiometer sensors are able to return, in other words max.

1V/V; a typical range is then 1000mV/V.

Bridge measurement is set by selecting as measurement mode either Bridge: Sensor or Bridge: Straingauge in the operating software. The bridge circuit itself is then specified under the tab Bridge circuit, wherequarter bridge, half bridge and full bridge are the available choices.

Two leads (Cand D) serve supply purposes, two other leads (A and B) capture the differential voltage. The fifth lead (F)is the Sense lead for the lower supply terminal, which is used to determine the single-sided voltage drop

along the supply line. Assuming that the other supply cable (C) has the same impedance and thusproduces the same voltage drop, no 6th lead is needed. The Sense lead makes it possible to infer the

If the sensor supply is equipped with the option “±15V”, a quarter bridge measurement is notpossible. The pin I_1/4B for the quarter bridge completion is used for–15V instead.

General notesThe SENSE lead serves to compensate voltage drops due to cable resistance, which would otherwiseproduce noticeable measurement errors. If there are no Sense lines, then SENSE (F) must be connectedin the terminal plug according to the sketches above.

Bridge measurements are relative measurements (ratiometric procedure) in which the fraction of thebridge supply fed in which the bridge puts out is analyzed (typically in the 0.1% range, corresponding to 1mV/V). Calibration of the system in this case pertains to this ratio, the bridge input range, and takes intoaccount the momentary magnitude of the supply. This means that the bridge supply's actual magnitudeis not relevant and need not necessarily lie within the measurement's specified overall accuracy.

The bandwidth for DC bridge measurement (without low-pass filtering) is also 5kHz (-3dB).

Any initial unbalance of the measurement bridge, for instance due to mechanical pre-stressing of the straingauge in its rest state, must be zero-balanced (tare). Such an unbalance can be many times the inputrange (bridge balancing). If the initial unbalance is too large to be compensated by the device, a larger inputrange must be set.

4.7.3.3.4 Balancing and shunt calibration

The amplifier offers a variety of possibilities to trigger bridge balancing (tare): Balancing / shunt calibration upon activation (cold start) of the unit. If this option is selected, all the

bridge channels are balanced as soon as the device is turned on. Balancing / shunt calibration via the on the Amplifier balance tab. In shunt calibration, the bridge is unbalanced by means of a 59.8k or 174.66k shunt. The results are:

Bridge resistance 120 350

Unbalance 59.8k174.7k

0.5008mV/V0.171mV/V

1.458mV/V 0.5005mV/V

The procedures for balancing bridge channels also apply analogously to the voltage measurement modewith zero-balancing.

NoteWe recommend setting channels which are not connected for voltage measurement at the highest inputrange. Otherwise, if unconnected channels are in quarter- or half-bridge mode, interference may occur in ashunt calibration!

4.7.4 Sensor supply module

The CS-5008, CL-5016 and CX-5032 is enhanced with a sensor supply unit, which provides an adjustablesupply voltage for active sensors.

The supply outputs are electronically protected internally against short circuiting to ground. The reference potential, in other words the sensor's supply ground contact, is the terminal GND.

The supply voltage can only be set for all measurement inputs in common. The voltage selected is alsothe supply for the measurement bridges. If a value other than 5V or 10 V is set, bridge measurement is nolonger possible!

The channels' maximum sampling rate is 10µs (100kHz). The analog bandwidth (without digitallow-pass filtering) is 5KHz (-3dB).

4.8.3.8.1 Background info on quarter-bridge configuration:

In quarter-bridge configuration the external ¼-bridge branch is connected via three cables, where thetwo current-bearing leads "+VB" and "-VB" must be symmetric (same resistance, thus identical length andcross-section). Under these circumstances, their influence (in terms of the offset, not the gain) iscompensated, so that no offset versus the (constant) internal half-bridge's potential arises.

If this symmetry condition is not met (e.g. if only two cables are used and the terminals "–VB" and "+IN" aredirectly jumpered at the terminal, the following offset drift would result due to the temperature-dependentcable resistance in series with the bridge impedance:

Assuming a (one-way) cable length of 1 m, we get:

Cu-cable: 0.14mm², 130m/m, cable length l=1m Cable Rk = 130m

Temperature coefficient Cu: 4000ppm / K

Drift Rk: 0.52m / K

Equivalent bridge drift (120 bridge) ¼ 0.52m / (K *120) = 1.1µV/V / K

Example: Temperature change dT = 20K 22µV/V (dT =20K)

Cable resistance values which aren't ideally symmetric would have a proportionally equal effect:e.g., 500m of cable with 0.2% resistance difference would cause the same offset drift of 1.1µV/V / K.

Along with the offset, a gain uncertainty given by the ratio between the cable resistance and the bridgeimpedance must also be taken into account. For 120 bridges, it remains under 0.1% for cable lengths ofapprox. 1m: (Cu-cable, 0.14mm², 130mΩ/m cable Rk/Rb = 1/1000 for l=0.9m)

There are three different procedures for cable compensation:

Connection of an additional 4th line: "+SENSE": * automatic calculated compensation on the condition of cable symmetry* online compensation procedure which also takes temperature drift into account* can be used with CF and DC-mode

Evaluation of the voltage drop along the cable to "-VB" by means of measuring the voltage differencebetween the terminals "-VB" and "+IN":* automatic computed compensation on the condition of cable symmetry* online-compensation procedure which also accounts for temperature drift * only can be used for DC

Offline cable resistance compensation by means of shunt calibration (on external quarter bridge):

automatic computed compensation on the condition of cable symmetry, including for the line "+IN"! This condition is generally not set for the 3-line Sense configuration!!

Assumption of nominal values for bridge impedance, shunt and gain: any deviation by the actualvalue in shunt calibration is interpreted as the influence of the cable resistance.

The underlying model results in a different correction than "classical" shunt calibration!

Offline compensation procedure which doesn't account for temperature drift

Used only with DC, since compensation is done only once, offline, if CF-mode is set, thisprocedure is performed in DC mode.

4.9 CS-7008, CL-7016

4.9.1 Compact measurement device for any sensor and signal type

CS-7008 and CL-7016 are 8- and 16-channel universal measurement devices, respectively, with samplingrates of up to 100kHz per channel. They are especially well suited to frequently changing measurementtasks. Practically every sensor- or signal type can be connected directly to any of the measurementamplifier’s all-purpose channels. The input channels are differential and equipped with per-channel signalconditioning including filters.



The devices have the following kinds of analog, non-isolated channels:

voltage measurements

voltage measurementswith adjustable supply

current

current feed sensors

charging amplifier

thermocouples

RTD (PT100) (2- and4-wire-configuration)

bridge - sensor

bridge - strain gauge


The eight measurement inputs whose terminals are the four DSUB plugs (ACC/DSUB-UN2) IN1 throughIN8 are for voltage, current, bridge PT-100 and thermocouple measurements. In addition the use of anICP-expansion plug are provided for. They are non-isolated differential amplifiers. They share acommon voltage supply for sensors and measurement bridges.

The analog channels support TEDS ; the technical specification of the CS-7008, CL-7016 .


Voltage: 50 V... 5mV

DSUB-plug: ACC/DSUB-UNI2

Within the voltage ranges 50 V and 20 V, a voltage divider is in effect; the resulting input impedance is 1M. By contrast, in the voltage ranges 10 V and 5mV, the input impedance is 20 M. For thedeactivated device, the value is approx. 1 M.

In the input ranges <20 V, the common mode voltage6 must lie within the 10 V range. The range isreduced by half of the input voltage. The input configuration is differential and DC-coupled.

6The common mode voltage is the arithmetic mean of the voltages at the inputs +IN and -IN, referenced tothe device ground. For instance, if the potential to ground is +10 V at +IN and +8 V at -IN, the commonmode voltage is +9 V.

Example: The device is grounded. Thus, the input GND is also at ground potential. If the voltage sourceitself is also grounded, it's referenced to the device ground. It doesn't matter if the ground potential at thevoltage source is slightly different from that of the device itself. But the maximum allowed common modevoltage must not be exceeded.

Important: In this case, the negative signal input -IN may not be connected with the device ground GND.Connecting them would cause a ground loop through which interference could be coupled in.

In this case, a genuine differential (but not isolated!) measurement is carried out.



The voltage source itself is not referenced to the amplifier ground but is instead isolated from it. In thiscase, a ground reference must be established. One way to do this is to ground the voltage source itself.Then it is possible to proceed as for "Voltage source with ground reference". Here, too, the measurement isdifferential. It is also possible to make a connection between the negative signal input and the deviceground, in other words to connect -IN and GND.

If the source's potentialcan't be adjusted (because it has a fixed, overlooked reference), there is a danger of damaging ordestroying the amplifier. If -IN and GND are connected, then in practice a single-end measurement isperformed. This is no problem if there was no ground reference beforehand.

Suppose a voltage source is to be measured which is at a potential of 120V to ground. The system itself isgrounded.

4.9.3.1.4 Voltage measurement: with zero-adjusting (tare)

In voltage measurement, it is possible for the sensor to have an initial offset from zero. For such cases, usethe operating software to select the measurement mode "Voltage enable offset calibration" for the desiredchannel. The input range will be reduced by the initial offset. If the initial offset is too large for compensationby the device, a larger input range must be set.


4.9.3.2 Current-fed sensors

For measurement of current-fed sensors, e.g. ICPs, the special connector ACC/DSUB-ICP2 is required.

NoteThis mode is not possible, if one channel is set to measure thermocouples.


4.9.3.3.1 Case 1: Differential current measurement

Current: e.g. 50mA ... 1mA

DSUB-plug: ACC/DSUB-I2

That connector comes with a 50 shunt and is not included with the standard package. It is also possibleto measure a voltage via an externally connected shunt. Appropriate scaling must be set in the userinterface. The value 50 is just a suggestion. The resistor needs an adequate level of precision. Payattention to the shunt's power consumption.

The maximum common mode voltage must be in the range ±10 V for this circuit, too. This can generallyonly be ensured if the current source itself already is referenced to ground. If the current source isungrounded a danger of exceeding the maximum allowed overvoltage for the amplifier exists. The currentsource may need to be referenced to the ground, for example by being grounded.

Because this procedure is a voltage measurement of the shunt, the channel has to be configured inimcDevices as a voltage measurement. The scaling factor is 1/R and the unit has to be A.

Note

There is a voltage drop across the resistances of the leadwires and the internal measuring resistance of120W which is proportional to the amperage. This lost voltage is no longer available for the supply of thetransducer (2.4V = 120W * 20mA). For this reason, you must ensure that the resulting supply voltage issufficient.

4.9.3.4 Bridge measurement


Measurement of measurement bridges such as strain gauges.The measurement channels have an adjustable DC voltage source which supplies the measurementbridges. The supply voltage for all eight inputs is set in common. The bridge supply is asymmetric, e.g., fora bridge voltage setting of VB = 5V, Pin C is at +VB = 5V and Pin D at -VB = 0V. The terminal–VB issimultaneously the device's ground reference.

Depending on the supply set, the following input ranges are available:

Bridge measurement [V] Input ranges [mV/V]

10 1000 ... 1

5 1000 ... 1

Fundamentally, the following holds:

For equal physical modulation of the sensor, the higher the selected bridge supply is, the higher are theabsolute voltage signals the sensor emits and thus the measurement's signal-to-noise ratio and driftquality. The limits for this are determined by the maximum available current from the source and by thedissipation in the sensor (temperature drift!) and in the device (power consumption!)

For typical measurements with strain gauges, the ranges 5 mV/V ... 1mV/V are particularly relevant.

There is a maximum voltage which the Potentiometer sensors are able to return, in other words max.1 V/V; a typical range is then 1000mV/V.

Bridge measurement is set by selecting as measurement mode either Bridge: Sensor or Bridge: Straingauge in the operating software. The bridge circuit itself is then specified under the tab Bridge circuit, wherequarter bridge, half bridge and full bridge are the available choices.

NoteWe recommend setting channels which are not connected for voltage measurement at the highest inputrange. Otherwise, if unconnected channels are in quarter- or half-bridge mode, interference may occur in ashunt calibration!


4.9.3.4.1 Case 1: Full bridge

A full bridge has four resistors, which can be four correspondingly configured strain gauges or onecomplete sensor which is a full sensor internally. The full bridge has five terminals to connect. Two leads (+VB and -VB) serve supply purposes, two other leads (+IN and -IN) capture the differential voltage. The 5th

lead (Sense) is the Sense lead for the lower supply terminal, which is used to determine the single-sidedvoltage drop along the supply line. Assuming that the other supply cable (+VB) has the same impedanceand thus produces the same voltage drop, no 6th lead is needed. The Sense lead makes it possible to inferthe measurement bridge's true supply voltage, in order to obtain a very exact measurement value in mV/V.

Please note that the maximum allowed voltage drop along a cable may not exceed approx. 0.5V. Thisdetermines the maximum possible cable length.

If the cable is so short and its cross section so large that the voltage drop along the supply lead isnegligible, the bridge can be connected at four terminals by omitting the Sense line. In that case, however,Sense and -VB must be jumpered. Pin Sense must never be unconnected!

4.9.3.4.3.1 Quarter bridge with 350Ohm option.

A built-in 120W completion resistor comes standard for bridge measurements. A 350W completion resistorfor quarter bridge measurements is also possible. When using this option, the scope of functionality islimited:

no direct current measurement with the included standard connectors ACC/DSUB-UNI2 is possible,but only with the optional connector ACC/DSUB-I2 having a 50W shunt (differential measurement);

no Pt100 3-line measurement is possible, but 4-line measurement is still possible.

General notesThe SENSE lead serves to compensate voltage drops due to cable resistance, which would otherwiseproduce noticeable measurement errors. If there are no Sense lines, then SENSE must be connected inthe terminal plug according to the sketches above.

Bridge measurements are relative measurements (ratiometric procedure) where the ratio of bridge supplyinput to bridge output is analyzed (typically in the 0.1% range, corresponding to 1mV/V). Calibration of thesystem in this case pertains to this ratio, the bridge input range, and takes into account the momentarymagnitude of the supply. This means that the bridge supply's actual magnitude is not relevant andneed not necessarily lie within the measurement's specified overall accuracy.

The bandwidth for DC bridge measurement (without low-pass filtering) is also 14kHz (-3dB).

Any initial unbalance of the measurement bridge, for instance due to mechanical pre-stressing of the straingauge in its rest state, must be zero-balanced (tare). Such an unbalance can be many times the inputrange (bridge balancing). If the initial unbalance is too large to be compensated by the device, a larger inputrange must be set.

Balancing / shunt calibration via the on the Amplifier balance tab.

In shunt calibration, the bridge is unbalanced by means of a 59.8k or 174.66k shunt. The resultsare:

The module's channels are designed for direct measurement with thermocouples and PT100-sensors.Any combinations of the two sensor types can be connected.

Note on making settings with imcDevicesA temperature measurement is a voltage measurement whose measured values are converted to physicaltemperature values by reference to a characteristic curve. The characteristic curve is selected from theBase page of the imcDevices configuration dialog. Amplifiers which enable bridge measurement, must firstbe set to Voltage mode (DC), in order for the temperature characteristic curves to be available on the Basepage.

4.9.3.5.1 Thermocouple measurement

The cold junction compensation necessary for thermocouple measurement is built-in.

In the imc connector ACC/DSUB-UNI2, the cold junction is located directly under the clampterminal strip and is measured automatically.

For connection with ITT VEAM plugs, the module comes with the appropriate PT1000 resistors formeasuring the junction temperature. Note, however, that these resistors are not installed in theplugs themselves but on the housing, so that they are actually at some distance from the realcontact point. This point's exact location is where the thermo-wires meet the electric contacts in theplug, basically where they are soldered or crimped. Since the temperature sensor PT1000 and thecontact point are separated in space, their temperatures can also diverge. This temperaturedifference can also lead to measurement errors. However, situations do exist where themeasurement results are valid; for example, inside a switch cabinet where the temperatureprocesses are stabilized, the internal cold junction compensation is in practice adequate.However, if the temperature processes in the device’s environment are not stable, a Pt100 in theconnector is absolutely necessary. This is certainly the case if:

o there is a draught

o if the module is used on-board a vehicle

o if cables with terminals of different temperature are connected

o if the ambient temperature is fluctuating

o whenever reliable and precise measurement is required.

The following circuit diagrams reflect each of the varieties with and without Pt100 in the connector. Westrongly recommend using a Pt100 in the connector for all thermocouple measurements. When usingDSUB plugs, the wiring is established automatically.


4.9.3.5.1.1 Case 1: Thermocouple mounted with ground reference

The thermocouple is mounted in such a way that it already is in electrical contact with the device ground /chassis. The thermocouple is connected for differential measurement.

The thermocouple itself already is referenced to the device ground. This is ensured by attaching thethermocouple to a grounded metal body, for instance. Since the unit is grounded itself, the necessaryground reference exists.

It is not a problem if the ground potential at the thermocouple differs from that of the device units by a fewvolts. However, the maximum allowed common mode voltage may not be exceeded.

Important: In this case the negative signal input -IN may not be connected to amplifier ground point GND.Connecting them would cause a ground loop through which interference could be coupled in. In this case, agenuine differential (but not isolated!) measurement is carried out.

Select in the operating software the measurement mode Thermocouple (mounted with groundreference).

imc C-series

4.9.3.5.1.2 Case 2: Thermocouple mounted without ground reference

The thermocouple is mounted so as to be isolated from the module's ground/chassis. The thermocouple'sconnection is differential, but the module itself supplies the necessary ground reference internally.

The thermocouple itself is not referenced to the module's ground, but is instead isolated from it. This isachieved by sticking the thermocouple on to non-conducting material.

In the operating software, select the measurement mode Thermocouple (isolated mode).

In this measurement mode, the unit itself provides the ground reference by having Terminals -IN and GNDconnected internally. Then a measurement which is practically single-ended (ground-referenced) isperformed. There is no disadvantage to this if there was no ground reference previously.

Important: The thermocouple itself may not be ground referenced! If it was mounted with a groundreference, there is a danger that a large compensation current will flow through the thermocouple's (thin)line and the module's plug. This can even lead to the destruction of the amplifier. Compensation currentsare a danger with every single-ended measurement. For that reason, single end measurement is really onlyallowed -and only then really necessary- if the thermocouple has no ground reference of its own.

When using thermocouples, the ICP-supply is no longer available.

4.9.3.5.2 Pt100/ RTD measurement


Pt100, RTD, platinum resistor thermometer. Along with thermocouples, PT100 can be connected directly in 4-wire-configuration. The 4-wire measurement returns exact results since it does not require theresistances of both leads which carry supply current to have the same magnitude and drift. Each sensor isfed by its own current source with approx. 1.2mA.

4.9.3.5.2.1 Case 1: Pt100 in 4-wire configuration

The Pt100 is supplied by 2 lines. The other two serve as Sense-leads. By using the Sense-leads, thevoltage at the resistor itself can be determined precisely. The voltage drop along the conducting cable thusdoes not cause any measurement error.

The 4-wire configuration is the most precise way to measure with a Pt100. The module performs a genuinedifferential measurement.


Use the software to set a Pt100 4-wire configuration, because the connection is made in the same way asfor the 4-wire case. The difference is that +IN/SENSE and –IN/GND must be jumpered inside theconnector. Note that the total cable resistance contributes to measurement error, and that this method isthe most imprecise and not to be recommended.

It is important, that the connection between +IN to Sense and -INto GND (-VB) is made directly at the module.

3-wire configuration is not always as precise as 4-wireconfiguration. When in doubt, 4-wire configuration is preferable.

4.9.3.5.2.4 Open sensor detection

The amplifier comes with the ability to recognize breakage in the sensor lines.

Thermocouple: If at least one of the thermocouple's two lines breaks, then within a short time (only a fewsamples), the measurement signal generated by the amplifier approaches the bottom of the input range ina defined pattern. The actual value reached depends on the particular thermocouple. In the case of Type Kthermocouples, this is around 270°C. If the system is monitoring a cutoff level with a certain tolerance, e.g.Is the measured value < -265°C, then it's possible to conclude that the sensor is broken, unless suchtemperatures could really occur at the measurement location.

The open sensor detection is also triggered if a channel is parameterized for "Thermocouple" andmeasurement starts without any thermocouple being connected. If a thermocouple is later connected afterall, it would take the period of a few measurement samples for transients in the module's filter to subsideand the correct temperature to be indicated. Note also in this context that any thermocouple cable'sconnector which is recently plugged into the amplifier is unlikely to be at the same temperature as themodule. Once the connection is made, the temperatures begin to assimilate. Within this phase, the Pt100built into the connector may not be able to indicate the real junction temperature exactly. This usually takessome minutes to happen.

RTD/PT100: If the leads to the PT100 are broken, then within a short time (only a few samples), themeasurement signal generated by the amplifier approaches the bottom of the input range, to about 200°C,in a defined pattern. If the system is monitoring a cutoff level with a certain tolerance, e.g. Is the measuredvalue < -195°C, then it's possible to conclude that the sensor is broken, unless such temperatures couldreally occur at the measurement location. In case of a short-circuit, the nominal value returned is also thatlow.

In this context, note that in a 4-wire measurement a large variety of combinations of broken and shortedleads are possible. Many of these combinations, especially ones with a broken Sense lead, will not returnthe default value stated.


4.9.3.6 Charging amplifier

The UNI8 module supports the DSUB-Q2 charge amplifier, which is a 2-chanel pre-amp in the shape of animc terminal connector enabling connection of two charge sensors via BNC.

The charge amplifier is recognized and adjusted automatically if either DC- or AC charge coupling isselected in the amplifier dialog. In order for these two coupling types to be displayed for the channelselected, the charge amplifier must be read by means of TEDS technology or it must be adjusted accordingto an appropriate sensor database entry.

The DSUB-Q2 is a module of the CRONOS-PL/SL family and is described in the corresponding manual.You will find that manual at the installation CD for imcDevices.

The description of the DSUB-Q2 and the technical specification .

4.9.3.7 Sensor supply module

The module is enhanced with a sensor supply unit, which provides an adjustable supply voltage for activesensors.

The supply outputs are electronically protected internally against short circuiting to ground. The reference potential, in other words the sensor's supply ground contact, is the terminal GND.

The supply voltage can only be set for all measurement inputs in common. The voltage selected is alsothe supply for the measurement bridges. If a value other than 5V or 10 V is set, bridge measurement is nolonger possible!

4.10.1 Overview

Noise and vibration analysis

CS-8008 is an 8-channel universal measurement device with sampling rates of up to 100kHz and abandwidth of 45,3kHz (@0.005dB) per channel. With active thirds, the sampling rate is up to 50kHz with abandwidth of 22,4kHz (@-3dB). Any kind of ICP™ sensors such as DeltaTron® accelerometers andmicrophones are supplied with power and can be directly connected to the measurement amplifiers, withthe 1/3-octave spectrum returned along with the signal’s plot over time.

It is additionally possible to connect voltage or current signals at the differential input channels, which areeach individually equipped with signal conditioning including filters.

In conjunction with its operating software imcDevices, the CS-8008 module is immediately ready to takemeasurements, and all of its functions are operable.

Additionally, the device can be expanded into a complete workstation for noise and vibration analysis, byrunning the (optional) imcWAVE software platform alternatively to imcDevices. Along with a spectrumanalyzer, there are packages for order tracking- and structure analysis for standards-compliantmeasurement of workplace noise, as well as pass-by analysis of noise from motor vehicles, and a modulefor free configuration of application-specific functions. Supplemental processing of the signals is possiblethanks to the signal analysis software FAMOS, while interfaces to ME´Scope™ and µ-Remus™ are alsoavailable.

4.10.3.1 Voltage measurement’s

Voltage measurements can handled as single ended- as well as differential measurements. In addition youcan choose between AC and DC. In the 25V and 50V ranges, a divider is switched in between whichlead to a reduced input impedance of 1MΩ or 2MΩ.

We recommend the differential mode, if the source which should be measured has a low impedance pathto ground. In cases of isolated sources single-ended should be chosen to avoid floating problems andbetter noise immunity. The various sources of interference can affect the measurement by a variety ofmeans, depending on the measurement environment; even the setting AC or DC for the coupling an affectthings differently. Therefore, check each individual case with multiple settings in order to achieve optimalmeasurement results.

4.10.3.2 1/3-octave calculation

The online processor on the amplifier card is able to calculate 1/3-octaves in real-time. The calculated1/3-octave channels appear in the software after the amplifier's analog input channels. A 1/3-octavechannel's data stream must be processed with the Online FAMOS function AudioBoardThirds, in order forthe 1/3-octave spectra to be displayed properly.

NoteIf the calculation of the 1/3-octaves is only enabled after delivery, the incremental numbering of thechannels in the software is shifted upward. In this way, it can happen that the channel designation on thedevice panel will deviate from its designation in the software interface.

4.10.3.3 Measurements with ICP sensors

The use of ICP™ e.g. DeltaTron-sensors® is supported by a 4mA current source. The sensor informationcan read directly from the sensor in accordance to the standard „TEDS - Transducer Electronic DataSheets (IEEE 1451)“.

The description of the CS-8008 .10 AC-coupling (or ICP) means a high pass filter at the input. To avoid drifting of the module, a high pass filter is always calculated,even if the user selects „without filter“.

11For voltages greater than the maximum voltage of the chosen range and lower than 70V, you may get a 5mA inputcurrent. Above 70V you can expect higher currents which can only be handled for 2ms.

5.12 Connectors

5.12.1 Connecting DSUB-15

With only a few exceptions (high voltage channels, current probes), all the measurement channels'terminals are DSUB-15 sockets. All measurement channels are connected at standard DSUB-15sockets, with the exception of the ICP-channels (BNC). The connection can be made with standardDSUB-15 plugs (male). However, the special imc-plugs include in the product package are designed forease and efficiency of use. The plug housing contains screw terminals for direct connection of lineswithout requiring soldering. For most measurement configurations the Standard terminal plugs areused, which are essentially 1:1 adapters for connecting DSUB-15 to the screw terminals. Adhesivelabels designed to denote the signal types can be attached to the appropriate channel groups' plugs.Aside from that, however, these plug are electrically identical. There are also special plugs which offeradditional functionality besides converting DSUB-pins to screw terminals.

The special thermo-plug (ACC/DSUB-T4) is needed for temperature-measurements. This plugcontains an internal PT1000 sensor for cold-junction compensation within its housing. It containsadditional "auxiliary" clamps for connecting PT100's in 4-wire-configuration, whereby the referencecurrent circuit is already pre-wired internally. The thermo-plugs for the various temperature modules arenot necessarily identical or thus interchangeable!

The Shunt-plug for current measurement with the isolated voltage channels (ACC/DSUB-I4) comeswith built-in 50 shunts. For direct display of the measurement results as current, this value must beentered in the settings interface as the scaling factor.

The ICP expansion plugs (ACC/DSUB-ICP) provide 4 isolated supply current sources and a capacitivecoupling. There are 2- and 4-channel models.

The universal plug for CS-7008, CL-7016, CS-5008, CL-5016 and CX-5032 contains a PT1000temperature sensor for thermocouple measurement. If these functions aren't required, a standardDSUB-15 plug can also be used for any other measurement types.

Cable shielding must always be connected to "CHASSIS" (DSUB housing, Pin1 or Terminals T15, T16).Some plugs provide VCC (5V), which can be loaded with 135mA per plug.

Note on the screw terminals used in the terminal plugsThe terminal's screw heads are only in secure electrical contact once they have been tightened onto aconnection wire. Therefore, measurements (for instance, using multimeter test prods) to check "loose"terminals can seem to indicate bad contacts!
