3-fold�Input�block�(Code�78404):with 3 measurement inputs for:• free chlorine (potentiostatic electrode)• Position feedback of an eventual servo motor with potenti-

ometer• a 0/4...�0 mA power entrance for the connection of a

disturbance factor or a conductivity measuring unit with upstream measuring amplifier

IMPORTANT!When free chlorine potentiostatic electrode is used in a 5-fold input block, it is possible to connect also a total-chlorine electrode. At the same time bonded chlorine is calculated by PC and displayed.

Output�board��(order�no.�78399)On the output block there are 5 integrated relay output and 3 electronic outputs (optocouplers).

The following output can be configured:• Controller output free chlorine

with different functions• Controller output pH value

with different functions• Controller output bonded chlorine

with different functions• Controller output conductivity

with different functions• DIN - contact: Free contact if all conditions of the DIN-

Standards are respected.• Contact for starting of the flocking pump.

The software configuration automatically assigns these outputs to the respective terminals in a sequential order- depending on the configuration of the TOPAXTOPAX® DX:1. Automatic controller free chlorine�. Automatic controller pH value3. Automatic controller bound chlorine4. Automatic controller conductivity5. DIN - contact6. Eco - contact7. Flocking contact

Depending upon output type, TOPAX® DXselects the next free relay output or optocoupler. The clamps are assigned in a firm order: clamps 87/88 to 95/96 for relays, or 81/8� bis 85/86 for optocouplers.

NOTICE!For further information on the terminal connection, refer to Chapter 4.6

Interface�board�RS�485�(order�no.�78406)The TOPAX® DX has the option of being fitted with a serial inter-face RS 485. The RS 485 allows you to transfer data to a PC. The data communication protocol installed is MODBUS.

With the RS 485 interface it is possible to connect more than one TOPAX® DX to a network. For this an address is to be assigned to each TOPAX® DX. In addition to this each TOPAX® DX is fitted with a computer-interface RS 485.

It is possible to have a maximum of 1000 m of data transfer with the RS 485 interface. Up to 14 TOPAX® DXs can be connected to a network with a PC.

An example of a network with more than one device is shown in chapter 17.

NOTICE!The data line is to be attached direct to the con-necting terminals of the TOPAX® DX (clip A and B). Separate clamping or branching boxes should not be set. The network address 10 is not permitted.

IMPORTANT!For the realization of a network with the TOPAX® DX and the structure of a bus system to a PC a computer cable "KAT.5 type 2X2XAWG24/1 (Lapp cable)" or better is to be used.

Using other cables can cause data errors and affect the data communication. The manufacturer is not liable for this.

Most modern computers are equipped with the serial computer interface R-S �3� and/or with USB - interfaces. For the connec-tion to a RS 485 network, an additional connector converter (RS 485 to RS �3� or RS 485 to USB) is necessary.

There are interface components in the under casing part of the main board in the TOPAX® DX. They are partially hidden from view by the output components (see diagram 4.6).

Fig. 4.6: RS 485 connections on the interface component’s board partially hid-den from view by the output components



NOTICE!The data line must be locked at both sides with a 120 Ohm line resistance and must be supplied a firm potential using the two link plugs on the two jumpers on the circuit board of the display of all la-test TOPAX DX versions.

Two link plugs/jumpers have to be connected to the TOPAX® DX (the last one in the network) for the 1�0 ohm switch, Pull-up and Pull-down resistances. The resistances are not active in its deliv-ered state. The resistance of 1�0 ohms on the PC side is applied via the connector converter.

The jumper plug-in slots are located in the upper casing on the display board, above the flat band-connection to the main board (see diagram 4.7).

TopView�SoftwareFor the remote indication a visualization program is offered in two versions. The program TopView mini is free of charge and can be downloaded from Internet.

4.5�Power�connectionsThe equipment may be installed and attached only by authorized and qualified electricians. Connections must be made according to the enclosed wiring diagrams.

NOTICE!Only work on electric connections when the device is disconnected from the power supply.

Insert the cables in the various connections screwed on the bot-tom side of the housing. After the installation, tighten all cable connections so that the required protection class is provided (see fig. 4.8).

Fig. 4.8: Cable connections for protected cable feedthrough on the rear side of the housing.

For the connection to the power supply and to the actuators, TOPAX® DX is equipped with special terminal clips (see fig. 4.9). For a better assembly these clamps are designed plug-ins (see fig. 4.10), whereby the maximum cross section is �.5 mm� for the power cord and 1.5 mm� for all other cable to the terminal clips.

Fig. 4.9 and 4.10: The principle of the connecting terminal to the technical com-ponents. Individual connecting terminals, removable for installation, of the technical components.

NOTICE!When choosing the line material, for installation and electrical connection of the device, observe the regu-lations of VDE 0100 “Provisions for setting up elec-tric power plants with nominal voltages below 1000 V“ or the individual national rules.

NOTICE!The equipment is not suitable for the installation in explosive conditions!



Connection�of�the�in-�and�outputs

NOTICE!Terminal clips allocation depends on the software configuration of TOPAX® DX. Terminal clips alloca-tion depends on the delivered equipment.

The delivered equipment is listed in the protocol, which is at-tached to the device. Use this connection diagram to wire the device and to put it in operation.

If the current software-configuration is not correct, the device has to be new configured before connecting (see Chapter 4.8). The display will show the new terminal diagram.

Voltage�supplyThis instrument has no power switch and is immediately opera-tive after the creation of the operating voltage. For this reason an external switch and/or protective switch is to be planned.

For the connection to the power supply on the main board, refer to the enclosed wiring diagram (see Chapter 4.6).

NOTICE!DO NOT let power be switched on via timer opera-tion!

Internal�fuseThe TOPAX® DX is internally secured with a micro fuse T�A. The internal fuse interrupts the power supply in the case of a short-circuit. For an additional external power supply protector, the value should not be below � A (slow-blowing).

The fuse is located in the under casing on the power supply board (see diagram 4.11 and 4.1�). To change the fuse the guard over the power supply has to be removed with the help of a cross-slot screwdriver (4 screws).

Fig. 4.11: Position of the power supply unit in the under casing.

Fig. 4.1�: Position of the fuse on the power supply board.

Sensor�technologyMeasuring cables may not be parallel when too close (less than 15 cm) to power switches and/or cables for power installation. Separate cable channels are to be used. Disturbing stray effects could otherwise falsify the measurement. At close distances, power supply and measuring lines may only cross at a 90° an-gle.

The maximum permissible length of the measuring cables de-pends on the kind of the sensor. When performing very ohmic measurements (e.g. pH or REDOX measurements) the following is to be considered:• Connections and patch cords must be clean and dry.• The permissible bending radius of the cable must be

respected.• The quality of the holding wires must correspond to the

defaults from the data sheet of the sensor.

IMPORTANT!If possible a continuous cable is to be used from the sensor to the measuring entrance. An extension of the cable by plugs or terminal socket increases the risk of disturbances due to contamination, humidity or excessive transition resistances.

Connecting�the�actuatorsWhen connecting your actuator the equipment must be switched off to prevent uncontrolled starting and malfunctioning.

IMPORTANT!To prevent the output relays from bonding in the case of a short in the load circuit, it must be separatly protected with the maximum relay switching current. For inductive loads, apply a protective circuit to the contacts of the relays (spark quenching). The manu-facturer recommends the usage of the interference suppression /spark suppression module (article 78614).

Replacing�the�batteriesThe life of the batteries (Type VARTA, CR1/� AA, � Volt, Lithium) provided with the internal instrument clock is approx. 5 – 10 years. When the batteries wear out causing a power shortage, a warn-ing message will be displayed on the instrument. The bat-tery is welded on the display circuit board (see fig. 4.13). It must be replaced by a skilled technician.

4.8�First�set-up�and�programming�guidelinesAfter the correct installation, switch on the power supply.

The TOPAX® DX is programmed by the manufacturer based on customers’ specs before shipment and is supplied along with a terminal connection diagram. Failure of the customer to sup-ply instructions on his purchase order, TOPAX® DX shall be pro-grammed by the manufacturer to the standard default settings (see chapter 19).

For the initial start-up the operator has to configure the TOPAX® DX and set its sensors and the installed actuating elements as well as set special functions. TOPAX® DX will automatically as-sign the right inputs and outputs based on these data and the corresponding terminals will be indicated. Ineffective or impos-sible configurations (for instance double assignment of the out-puts) are not admissible.

After a successful configuration the TOPAX® DX starts up with a standard display (see chapter 16). A subsequent renewed con-figuration can be carried out via the Service-Menu (see chapter 16, menu 5 “Configuration”).

IMPORTANT!All menus of TOPAX® DX are shown a ID-number marked in the bottom line on the left display corner.(see Fig. 4.16).

NOTICE!At start-up the controller outputs of your TOPAX® DX will be function-less for approx 60 seconds. This time is required to stabilize the electrochemical sen-sors connected. During this time the status display shows the message "starting in..... s" (countdown seconds are progressively shown). At the end of this time TOPAX® DX is fully operative.

NOTICE!In order to prevent unauthorised manipulation, the TOPAX® DX has a password protection (see Chapter 16, menu 5.9)

4.9�Next�stepsAfter a successful configuration the next steps should be:• Connect the sensors and the actuating elements - if not

already connected• Calibrate the sensors to the measuring output (see chapter

5 and 6)• Set up the set point of the measuring inputs (see chapter

16, menu 1.1)• Set up the control (see chapter 16, menu �.1)• Configuration of the regulating outputs (see chapter 7)

NOTICE!The configuration of the in- and output can be re-called via the point “configuration” in the menu “service” whilst in operation (see chapter 6, menu 5). Here the changes to the terminal plan are written in red figures.


Chapter�5:�Measuring�values�inputs

5.�Measuring�values�inputsThis chapter exemplifies the chemical and physical correlation, which is necessary to understand the behaviour of the input measuring values.

The input measuring values are examined for:• Free chlorine• pH value• Redox potential• Temperature• Total chlorine and display of bonded chlorine• Conductivity

In doing so an important element is the calibration of the sen-sors.

NOTICE!When set up the unit for the first time, care should be taken to perform individual calibration of each out-put immediately after connecting the sensors in the system. TOPAX® DX is designed to perform moni-toring of all calibration processes based on reason-able parameters (zero point and conductance) and the measurements are accurately documented. Non calibrated and „Roughly calibrated” value inputs are

marked out in clear text. „Roughly calibrated” values are shown on the main display in red.

NOTICE!Please note possible time delays due to the initial running times of the sensors.

The limits of „Roughly calibrated” are:

measurement�value limitsslope rate pH <53 mV/pH or

> 61 mV/pH

zero point pH < -40mV or> 40mV

slope rate Redox < 0,85 mV / mV or> 1,� mV / mV

slope rate chlorine atamperometric or potentiostatic measur-ing cell

< 3 µA / mg/l or> 100µA / mg/l

slope rate chlorine with encapsulated electrode (0..�.00 mg/l)

< 3mA / mg/l or> 13mA / mg/l

slope rate chlorine with encapsulated electrode (0...5.00/10.00 mg/l)

< 1mA / mg/l or> 5.�mg/l

The remark „roughly calibrated” sheds light on the calibration quality and the conditions of the electrochemical electrodes.

Look for calibration faults and eliminate them. Replace the sen-sors as soon as possible, if necessary. You can use the sensors unchanged until replacement.

5.1�Free�chlorine�measurements�inputThe value of „free chlorine“ is dependent on the Ph-value of the streaming water flow which results form the reaction of chloride ions to different Ph values. This relationship further determines the chlorine dissociation curve (see fig. 5.1).

Fig. 5.1: The dissociation curve shows the dependence regarding the pH value

For photometric measurements the pH-value of the sample is soaked in a pH-buffer of approx 6,5 in order to obtain a meas-urement of a higher content of effective chlorine than actually available in the water stream. In the presence of high pH-values significant differences will occur between expected and actual disinfection if assessed by photometric analysis. The main display will show therefore � free chlorine values: The results of photo-metric analysis and the content of effective chlorine to assure the germicide effect at the pH-value of the process medium.

Technical dataPower signal is received from excess chlorine detector using � electrodes, a potentiostat or a membrane-enclosed sensor (measuring signal 4...�0mA).

Following measuring ranges are possible:

Accuracy ± 1 % after calibration



Calibration of amperometric, excess chlorine detector with 2 electrodes ((CS120)Before starting the calibration, the upper value of the measuring range of the sensor must be defined at the TOPAX® DX (see Chapter 16, menu 5.1).

Then the input must be calibrated with a �-point calibration (see Chapter 16, menu 1.�):

The physical value (µA) measured at the sensor is shown on the display during calibration.

Calibration method 1: Zero-point calibration

To perform zero-point calibration, operate the detector in chlo-rine-free water or just stop the water flow through the instru-ment. The value of the physical quantity shown on the display (approx 5-10 µA) can be saved as soon as it stops changing. The device automatically changes to the next menu section.

Calibration method �: DPD

The sensor is operated with sample water. If the physical value on the display does not change anymore, the chlorine concentration in the sample water is determined by means of the DPD method. In order to avoid signal variations and consequent reading errors, water must be taken at the sensing element and the actual sig-nal must be saved directly in the TOPAX® DX upon taking of the water sample. The content of chlorine in water is measured by means of the DPD method. The value must be set in the control-ler and saved by pressing OK.

After storage the slope value of the chlorine sensor is shown. The typical resistivity value is approx. �5–35 µA (depending on water type) per mg/l of free chlorine. The accuracy of resistivity measurements is monitored throughout the process.

1-point calibration is sufficient (reference value �) for validation of the chlorine content after optimization.

Calibration of potentialstatic measuring cell (PM)Before starting the calibration, the upper value of the measuring range of the sensor must be defined at the TOPAX® DX (see Chapter 16, menu 5.1).

Then the input must be calibrated with a 1-point calibration (see Chapter 16, menu 1.�):

Reference value.-.DPD

The sensor is operated with sample water. A nearly stable physi-cal value should be displayed. In order to avoid signal variations and consequent reading errors, water must be taken at the sens-ing element and the actual signal must be saved directly in the TOPAX® DX upon taking of the water sample. The content of chlorine in water is measured by means of the DPD method. The value must be set in the controller and saved by pressing OK.

After storage the slope value of the chlorine sensor is shown. The typical resistivity value is approx. 35 µA (depending on water type) per mg/l of free chlorine.

The accuracy of resistivity measurements is monitored through-out the process.

After calibration of the free-chlorine is completed, you may even-tually switch to calibration of the “total chlorine detector” by sim-ply pressing on „continue".

NOTICE!When measuring the free chlorine with a potentio-stat it is possible to perform a compensation of the pH-value and temperature by simply connecting a pH-electrode and a temperature sensor to TOPAX® DX (see chapter 16, menu 5.1 "inputs").

Calibration of encapsulated electrodeBefore starting the calibration, the upper value of the measuring range of the sensor must be defined at the TOPAX® DX (see Chapter 16, menu 5.1).

Then the input must be calibrated with a 1-point or a �-point calibration (see Chapter 16, menu 1.� "Calibration"):

NOTICE!When measuring free chlorine by means of a fully encapsulated electrode, make sure to connect both terminal clips 51 B and 52 B. These clips are respec-tively used to feed the 20 mA signal of the electrode into the controller and to supply 24 VDC operating power to the sensing electronics of the electrode.

zero-point calibration (�-point calibration)

Zero point calibration of the sensing electrode is normally not a must-requirement, as tuning of the 4...�0 mA output signal of the electrode is done on input 4...�0 mA (4 mA corresponds to 0,00 mg/l free chlorine).

However, a zero-point calibration may be still required due to the tolerances of the sensing electronics of the electrode. For this reason the zero-point must be set upon first setup of the instru-ment. For this purpose the measuring water extraction must be operated with chlorine-free water.


The sensor is operated with sample water. A nearly stable physi-cal value should be displayed. In order to avoid signal variations and consequent reading errors, water must be taken at the sens-ing element and the actual signal must be saved directly in the TOPAX® DX upon taking of the water sample. The content of chlorine in water is measured by means of the DPD method. The value must be set in the controller and saved by pressing OK.

After storage the slope value of the chlorine sensor is shown.


IMPORTANT!The signal from the excess-chlorine sensing detector is converted by the electrode into an impressed cur-rent pulse of 4...20 mA. Whenever your TOPAX® DX features a lower value than 3.5 mA, an alert message is displayed „total chlorine sensor failure", the alarm relay is switched.

The voltage signal transmitted by the combination electrode is proportional to the pH value. This voltage is defined by the Nernst voltage. The Nernst voltage ist he change in voltage per pH unit. It depends on the temperature of the medium to be measured (see corresponding technical literature or German Standard DIN 19�61).

The following table shows the temperature dependence of the Nernst voltage:

The Nernst voltage is measured between the pH glass electrode and a reference electrode. Mechanically these two electrodes are integrated in a pH combination electrode.

CalibrationCalibration of the electrode may be performed by ways of „�-point calibration“ with � buffer solutions or by „1-point calibra-tion” with final input of the resistivity value. The mandatory condi-tions for using „1-point calibration“, is that the resistivity of the sensing electrode must be priory measured in a lab.

The actual voltage of the electrode and the design value of buffer solution are displayed on the TOPAX® DX during calibration so that the electrode can be actually graded while performing the calibration process.

The reaction time for any brand new electrode is just a few sec-onds and the electrode is considered as fully adjusted when the physical reading becomes stable. In the case of older combina-tion electrodes the reaction time may be longer.

The single-rod measuring cell is directly connected to the input terminal of the board of the input module 5-fold (see section 4.3).

2-point calibrationThe physical measuring value (mV) on the electrode is displayed in the menu (see chapter 16, menu 1.� "calibration") along with the design measuring value that should be ideally assessed for the pH.

Buffer 1 - zero-point calibration

Submerge the pH combination electrode in a buffer solution which is equivalent or close to the zero point of the electrode. The ideal zero point (O mV) of the combination electrode is pH 7.00, the actual zero point, however, deviates slightly from this value. For zero-point calibration a Lutz-Jesco buffer solution of pH 6.80 is available. When soaking the Ph-electrode in this solution, a voltage of 1� mV should be displayed on the TOPAX® DX. The physical value actually measured is, however, always different from the theroretical one.

When the physical value on the display becomes stable, you may save the calibrated value by pressing „OK“.

IMPORTANT!Should the actual measured voltage strongly differ from the design zero-point of the electrode, it means there is a zero-point drift of the electrode. Zero-point drift should not exceed the specifications of the DIN Standards 19265. In the event of zero-point drift exceeding ± 40 mV, TOPAX® DX warns you about possible bad prove calibration.

Buffer � - slope calibration

Accurately clean the electrode with deionised or distilled water before calibration of the resistivity.

NOTICE!Avoid rubbing off glass electrodes as you may pro-voke accumulation of static electricity in the elec-trode which in turn would result into faulty readings!

For slope calibration a buffer solution must be used which differs at least � pH units from the zero point. For zero-point calibration a buffer solution of pH 9.�7 is available from the manufacturer. Should you use a different buffer solution for calibration of the resistivity, you first need to set TOPAX® DX to the pH of your other solution. When soaking the Ph-electrode in this buffer solution (Ph = 9.�7), a voltage of -134 mV should be displayed on the TOPAX® DX. The physical value actually measured is, however, always different from the theroretical one. Confirm presetting by pressing the “OK“ key.

Then the slope value of the combination electrode is displayed. In accordance with the DIN Standards 19�65 the resistivity if an electrode should range between 5� and 59 mV per pH-value.

Zero-point stability and accuracy of the measured resistivity are consistently monitored.

IMPORTANT!If the slope value differs considerably from these values, check the combination electrode or the connecting cable and the plug connectors. Should zero-point and resistivity values of the combination electrode exceed the admissible tolerances, the sys-tem notifies the operator with a warning message. In this case provide for immediate replacement of the electrode.

IMPORTANT!Store buffer solutions in a cool and dark place! Ob-serve its durability. The buffer solution must not be contaminated. Therefore do not put the single rod measuring cells directly from one buffer solution into another solution.

1-point calibrationThe 1-point calibration can also be used for the pH single rod measuring cell calibration (see Chapter 6, menu 1.�).

Submerge the pH combination electrode in a buffer solution which is equivalent or close to the zero point of the electrode. The ideal zero point (O mV) of the combination electrode is pH 7.00, the actual zero point, however, deviates slightly from this value. For the zero point calibration a buffer solution of pH 6.80 (TOPAX® DX default setting) is available from the manufacturer.

When soaking the Ph-electrode in this solution, a voltage of 1� mV should be displayed on the TOPAX® DX. The measured physi-cal value however always differs from the design one.

When the physical value on the display becomes stable, you may save the calibrated value by pressing „OK“.

Now enter the resistivity of the electrode.

IMPORTANT!Should the actual measured voltage strongly differ from the design zero-point of the electrode, it means there is a zero-point drift of the electrode. Zero-point drift should not exceed the specifications of the DIN Standards 19265 (±40 mV).

Offset compensationIn accordance with DIN 19643, the control of the pH value is to be made with an electrical metric pH value measurement.

By external influences it can be possible that the pH value of the electrical metric measurement, measured by hand with the pho-tometer, deviates by a constant value. The menu "offset align-ment" offers the posibility to eliminate the difference.

NOTICE!The offset value is set to „0“ after every new calibra-tion.

Technical data

Power ValuesInput Voltage signal of a Redox single-rod measuring cell

(0-1000 mV)

Input resistance 109 Ohm


The Redox potential is measured with the help of the Redox sin-gle-rod measuring cell. It measures the voltage which exists in the water due to oxidizing and reducing ions.

CalibrationCalibrate the combination electrode during startup. For calibra-tion of the Redox single-rod measuring cell only one reference value must be set. The physical value (mV) measured at the sen-sor is shown on the display during calibration.

For calibration a buffer solution is required in order to meas-ure a defined voltage in connection with the REDOX combina-tion electrode. (given value: 468 mV). This value can be changed when using other buffer solutions and/or combination electrodes with other electrolytes. To change, use the buttons on the control panel. The voltage actually measured is shown on the display during calibration. This value has a small deviation from the given value of the buffer solution. The deviation should not be bigger than approx. 10%.


After a reaction time (approx. 1 minute) the physical value does not change anymore.

The reference value can be now entered and saved by pressing the “OK” button.

IMPORTANT!With old combination electrodes the response time can become larger and vary. Furthermore the meas-ured value can be largely different from that of the buffer solution. This signifies that the combination electrode must be checked and possibly replaced.

The single-rod measuring cell is directly connected to the input terminal of the board of the input module 5-fold (see section 4.3).

IMPORTANT!The measuring signal of the REDOX combination electrode can be also configured for controlling the disinfection.

Do not use other than a two-wire "Pt 100" as sensor.

CalibrationThe zero point of the measuring input is set in the factory. This measuring input can be adjusted with the temperature of the measuring water of the TOPAX® DX (see chapter 16, menu 1.� "calibration").

For this purpose, measure the temperature of the measuring wa-ter with a comparative thermometer and set the measured value as reference in the TOPAX DX.

Power ValuesSensor Total chlorine measuring cell (encapsulated electrode)

Measuring signal 4...�0 mA corresponding measuring range of the measuring electrode


CalibrationThe total chlorine measurement is pH and temperature-compen-sated. For the measurement of the free chlorine the potentiostatic measuring cell is necessary, otherwise a total chlorine measure-ment is not possible. In connection with the measurement of total chlorine and free chlorine the bonded chlorine is displayed in the TOPAX® DX.

Measurements of bonded chlorine are performed using and encapsulated electrode. This total chlorine measuring cell con-sists of a sensor part with integrated electronics and supplies a 4...�0 mA measuring signal according to the measuring range 0.00...�.00 mg/l.


The sensor is operated with sample water. A nearly stable physi-cal value should be displayed. In order to avoid signal variations and consequent reading errors, water must be taken at the sens-ing element and the actual signal must be saved directly in the TOPAX® DX upon taking of the water sample. By means of the DPD method the total chlorine content in the measuring water is determined. The value must be set in the controller and saved by pressing OK. Afterwards the slope is indicated in the measur-ing cell. The accuracy of resistivity measurements is monitored throughout the process.

For the announcement of bound chlorine at the TOPAX® DX it is necessary that the total chlorine and the free chlorine, the pH

value and the temperature of the measuring water with the same TOPAX® DX DX are measured.

Record the increasing trend after brine or sea water baths fol-lowing the quality of the brine. If an electrolytic cell, e.g. from Technopool, is used to generate the free chlorine concentration, brine water must be available as a precondition.

The conductivity of the measuring water can be measured and the concentration be kept constant. The measuring signal is con-verted into a standard 4...�0 mA current signal by a separate measuring amplifier.

CalibrationThe measuring input has to be calibrate (see chapter 16, menu 1.� "calibration"). Setting of the zero point is not necessary. Only the reference value is to be examined and adjusted if necessary. Afterwards the slope is indicated in the measuring cell. The ac-curacy of resistivity measurements is monitored throughout the process.

Chapter�6:�Explanation�of�digital�inputs

6.�Explanation�of�digital�inputs

GeneralIt is possible to interrupt the control process and to activate an alarm by external digital signals. These inputs can be configured in the menu as "normally close" or "normally open" and the level inputs must be additionally deactivated.

6.1�Start-up�lag�timeThe digital signal inputs causes alarm and/or auxiliary functions, which interferes with the normal functions of the automatic con-troller.

If a digital signal input is operated and if the appropriate func-tion is implemented, this has mostly effects on the quality of the measurement and the regulation will be set to "0%". After that the automatic work of the automatic controller is again config-ured; if a start-up lag time occurs, the sensors reset themselves to the automatic measuring procedure.

NOTICE!This start-up lag time is activated: • after filter cleaning • after a "remote switchoff" (measuring water shortage) • after the calibration of a measuring input • when switching on a supply voltage

6.2�Deactivation�of�the�controller�function�with�alarm�signaling�in�the�case�of�lack�of�sample�water

measuring�water�shortageBy an external flow contact the automatic controller functions activates. If the function "shortage of measuring water" is ac-tive and it arises a shortage of measuring water, all automatic controller outputs are set to "0 %", thus switching alarm relays; the announcement "shortage of measuring water” appears in the display.

6.3�Controller�function�deactivation�(filter�cleaning)�without�alarm

This function can be activated by an external contact during filter cleaning. The automatic controller functions are set to "0 %" and the "Filter backwash” appears in the display during this time. When the contact is released, the initial value of the time before the filter cleaning is set for a starting time. After this starting period, the control process is carried out automatically.

This starting lag time is necessary. After a filter cleaning the measured values are not to be used immediately for regulation, since these must reset themselves again to the measuring water. Therefore the regulation is set on the automatic controller power output, as it was prior the filter flushing. The regulation of the measured value begins only after the deceleration time is over.

6.4�Pre-alarm,�alarm�and�warning�"level�dosing�pump"By an external contact e.g. of the level switches of an intake, the connection between the clamps �1 and �� (intake dosing pump

free chlorine) and/or. �5 and �6 (intake dosing pump pH value) can be opened and/or closed. The announcement "free chlorine level early warning" and/or "pH value level early warning" appear in on the display and the alarm relay switches. The chemicals must be refilled.

No chemicals refilled can be opened and/or closed after a further contact of the intake connection between the clamps �3 and �4 (intake dosing pump free chlorine) and/or �7 and �8 (intake dosing pump pH value). The announcement “free chlorine level Alarm" and/or "pH value level Alarm" appears on the display and the alarm relay switches; at the same time the automatic control-ler output line of the respective input is set to 0.

NOTICE!If the level inputs in the menu "Service digital inputs" are activated, the level switches are to be attached to the clamps. If no level switch is attached, the inputs are to be deactivated.


Chapter�7:�Explanation�of�measuring�values�outputs

7.�Explanation�of�measuring�values�outputs

GeneralWith the configuration of the TOPAX DX an input type was as-signed to each controller.

Possible are:• Servo motor with potentiometer (with feedback)• Servo motor without potentiometer (without feedback)• Pulse frequency (electronic / optocoupler) • Pulse frequency (Relay) • Continuous (current) output 0/4...�0 mA• ON/OFF (Relay)

7.1�Output�typesThe regulating outputs can be calibrate in several aspects (see chapter 16, menu 5.� "outputs"):

ON/OFF�(Relay)Relay output - if the adjusted value are excessive the relay switches, a hysteresis is adjustable.

Pulse�length10..1�0 seconds cycle duration, relay output (e.g. for solenoid valves).

Depending on the control deviation and the defined control pa-rameters, the relay pulls in or drops out for the set cycle dura-tion. If the cycle duration is 30 seconds and the controller output power is 40 % the relay pulls in for 1� seconds and it does not for 18 seconds.

Pulse�frequency10...�00 pulses per minute as a adjustable maximum

The pulse frequency depends on the deviation and the set con-troller parameters, i.e.: at a controller output of e.g. Y=�5% and a pulse frequency of 100 pulses/minute, the controller sends �5 pulses/minute.

Observe the maximum stroke frequency of the connected pump.

Electronic output (optocoupler output)Pulse frequency output for controlling solenoid-driven dos-ing pumps or motor-driven pumps (e.g. MAGDOS or MEMDOS pumps) with intelligent electronic control unit. Ensure the right polarity.

Relay outputPulse frequency output, pulse length output, 3-point-step output (for servo motors) or "ON/OFF" for the control of magnet dosing pumps, hose pumps or single solenoid valves.

3-point-step�output�for�servo�motorsRelay output (e.g. for chlorine control valve C7700).

A acknowledging potentiometer can not be connected with servo motors with position feedback (1-10 kOhm). The acknowledging potentiometer is to be adjusted. For calibration the servomotor is

started first. The voltage, which lines up over the acknowledging potentiometer, is indicated in the position of the potentiometers (voltage display between 0 and 3 V). After the stop position has been reached, the servomotor is stopped automatically. The alignment is accomplished and is to be stored in the TOPAX® DX.

The switching hysteresis can be set from 1-�0%.

A servo actuator without feedback can also be operated. This is to be selected with the configuration.

If no positional feedback is available, measure and adjust the motor life (see chapter 6, menu 5).

NOTICE!Entering a wrong motor life may prevent accurate controller functioning in which case you would re-ceive no warranty coverage by the manufacturer. The motor cycle time is set by the factory at 120 seconds which corresponds to the cycle time of the motor of the chlorine gas valve C7700.

Continuopus�control�output�(20�mA�current�output)For automatic controllers a continuous control output of 0/4...�0 mA can be configured for the control of continuous actuators.

The current varies between 0 and �0 mA depending on the de-viation. max. load: 500 Ohm

It can be selected between:• 0...�0 mA,• 4...�0 mA,• �0...0 mA and• �0...4 mA.

7.2�Output�limit�switchThe output of each automatic controller can be limited in its up-per value. For this reason, you must enter the maximum propor-tional value of the actuators.

Example: a value of 80% operates the automatic controller to a maximum of 80 %. The algorithm of the automatic control is however computed further on 100%. It is to be noted that the automatic controller parameters are selected accordingly.

The smallest adjustable value for the maximum limit is 50 %.

This limit is useful for example if you are running a very large chlorine regulator valve and you want to ensure a sensible regu-lation.

7.3�Actuator�elementsPumps, solenoid valves etc. which are controlled by the TOPAX DX are called control elements.

Depending on the final control element used, different control functions can be set. Possible options are a continuous output with an impressed current (0/4...�0 mA), or control outputs (with pulse frequency). The latter can be controlled as electronic (opto-coupler) or relay outputs.


Chapter�8:�Controller�explanation

8.�Controller�explanation

DefinitionsTerm Definitionactual value (X) The actual value of X of the measured value for the

respective sensor is constantly indicated.

Setpoint (W) Set point W of a control system defines the value at which the controller has to settle the process and keep it constant.

Control deviation (X-W)

Control deviation X-W occurs if the actual value X of the measurand differs from set point W. Control variable Y results from the control deviation and the control parameters set.

Control vari-able Y

Control variable Y of a control system defines the value which the controller transmits to the final control element depending on the parameters set and control deviation X-W (between 0 % and 100 %).

8.1�Proportional�controller�(P�controller)

Proportional range Xp(proportional effect or amplification of the controller)

The proportional range Xp (p-range) of a proportional controller indicates by which value the measured variable X must deviate from the default value W, so that the correcting variable is Y = 100%. If the control deviation is less, the control variable is re-duced as well in terms of percentage.

Control variable Y of a P-controller is influenced only by the con-trol deviation (X-W)in terms of percentage.

The P-range is indicated in "%" and always refers to the measur-ing range final value.

The proportional range is thus an indirect measure of the control-ler amplification K

R:

KR = 100% / Xp %

With a Xp range of 50 % the controller amplification is :

100 /50 = � -> controller amplification KR = �

Xp = 50 % means that the control variable Y changes around 100 % when the actual value deviates by 50 % from the default value (related to the measuring range final value).

8.2�Proportional-integral-derivative�controller�((PI,�PID�controller)

Reset time Tn(integral effect of PI controller)

The integral time of a PI- or PID-automatic controller is called reset time Tn. The integral time is the time required by the ma-nipulated variable Y in the case of a constant deviation between default and actual values in order to reach the same change of the output signal, which is immediately produced by the p-rate after the jump of the deviation between default and actual values.

�Example�for�proportional�range�and�reset�timeXp = 50 % (amplification = �)

Tn = 3min

(sudden change of the actual value by 15%)

After a sudden deviation of the actual value from the default val-ue by around 15 % (X-to-W), the correcting variable Y changes by the same rate as the controller amplification, that is twice the Xp value or by 30%.

Because of the integral behaviour, the manipulated variable continues to increase as long as the X-to-W deviation remains present and after a time Tn = 3 minutes reaches once again 30 % of correction variable increase.

control�variable Set�valueMeasuring range for free chlorine 1,00 mg/l

Xp (P-range) 50 %

Tn 3 minutes

Y (Immediate power output of the automatic controller)

30 % by Xp

Y (output power of the automatic controller after 3 minutes)

60 % through Tn

Derivative time Tv

(differential action of PID controller)

By a differential function a correction factor is entered in the controlled system when the controlled variable begins to differ from the default value. The correcting variable depends on the speed by which the default-to-actual deviation takes place (thus not the actual deviation). The duration of the correction factor is determined by the reproaching time Tv. If the controlled variable does not change, thus the rate of change is "0", the correction factor and the time constants Tv caused by the differential rate drop to "0" (even if the actual value keep deviating away from the default one). The fact that the regulation leads the actual value to match with the default one is caused mainly by the integrals por-tion of the automatic controller. The differential rate often helps implementing the controller result because it acts against the trend to deviate.

8.3�Calculation�of�setable�valuesIn order for the controller to process actual values of free chlorine and Ph even in the presence of very slight deviations (almost close to the default values), it must be adjusted to the controlled system. This is done via the control parameters Xp for the pro-portional area, Tn for the reset time of the integral range and the reproaching time Tv for the differential range.

The determination of these settings can take place by means of taking up the step response of the controlled system. In addition the control members must suddenly and manually change from "CLOSE" (0 %) to "OPEN" (100 %) or e.g. from 30 % to 50 %.


Chapter�8:�Controller�explanation

The following formula can be used for calculation of reference values:

Xp ~ 0,83 · ΔX / Δt · Tu

Tn ~ 3,3 · Tu

Variable DescriptionYh setting range (e.g. valve fully up or 100% of the dosing pump

ΔX / Δt Gradient of the measured curve (see Fig. 8.�)

to Time of change of control variable Y

Tu lag time (s)

Vmax maximum increase rate of the measured variable

Vmax Xmax / Tg = ΔX / Δt

In order to meter chlorine gas, you need accounting for the speed of the chlorine gas valve. The value of Xp is computed for a drive speed from 0 % through 100 % in 60 seconds. A slower opera-tion would show the same trend as a bigger proportional range Xp. In order to adjust this, the Xp value must be first reduced at slower operation and vice versa.

The following formula can be used:

XP new = XP · 60 sec /Ty

Ty = Motor regulation time

As we are dealing here with approximate values, a certain im-provement of the controlled variable can sometimes be obtained by changing the Xp value after certain time. If the regulation should react too slowly or on the contrary too fast, smaller Xp and smaller Tn would result into a faster automatic controller action and in a larger Xp and/or Tn slower-acting settings.

8.5�Controller�directionThe control direction can be set for each controller. Possible options:• value boost (display arrow "up")• value drop and (display arrow "down")• �-side controller (only free chlorine and pH value)

The connection terminals are also marked with an arrow.

8.6�Base�load�meteringA basic load dosage can be configured outside of the range of control. This dosage takes place even if the PID automatic con-troller output is 0 %. If a basic load is configured, this value is represented in blue on the display screen in the y-display. The y-display of the automatic regulation is represented in green. In the status display, this condition is identified by a "+" after the y-display. It should be noted that this basic load is always effec-tive and independent of the regulation of a certain percentage of the control elements, although the automatic controller does not request any dosage. The basic load is separately adjustable for each output to a maximum of �0 % of the control range.

8.7�Manual�operationAutomatic controllers feature the possibility of a manual opera-tion mode.

If an automatic controller is hand-operated, then a large "M" behind the "Y" will appears in the status display and the y-dis-play on screen will be "blue". In addition the hand-operated is indicated in the lower line.

In the menu of the manual settings the controller output can be adjusted to any value between 0 % and 100 % and saved di-rectly.

NOTICE!Manual operation is not reset automatically.

9.�Alarms

9.1�Measuring�values�alarmsFor each measuring input a minimum and a maximum alarm can be set. In the case of a value falling above or below this value, the alarm is shown and an alarm relay as common alarm trig-gers. The alarm settings of the relay and the automatic controller belonging to this measuring input can be differently evaluated. The time delay of the alarm is adjustable (delay)

9.2�Emergency�stop�(Y-alarm)TOPAX® DX is equipped with a safety disconnect. Should the out-put power of the controller reach more than 95 % due to unex-pected events as for example a faulty sensor, a warning alarm is displayed for the controller to reset the controller power output to 0 %. This function is activated by default. The time is adjustable.

Moreover adjusted basic loads are switched off in the event of an emergency stop.

All alarms are displayed in clear text form on the screen. The alarm relay is activated and the measured value, which caused the alarm, is shown in red.

NOTICE!The alarms are represented in red on the display. After clearing, reset the alarms by pressing twice the OK key button.

(see chapter �1 "Troubleshooting/diagnostics" also)

10.�Analogue�power�outputs�0/4...20�mA�for�remote�displayFor the remote indication of the measured values, TOPAX® DX has a similar output for each measured value input 0/4... �0 mA.

The settings 0... �0 mA or 4... �0 mA see chapter 16, menu 5 "recorders". The adjustment of the outputs to external devices is done in menu � (see chapter 16, menu �.3 "Recorder"). Any measurement can be assigned to a minimum value or a maxi-mum value.

In order to check the outputs and for adjust it to the attached instruments and devices, you submit the �0 mA outputs to a test signal (see chapter 16, menu 5.� "outputs").

The signal can take each value between 0 and �0 mA. That is separately possible for the configured controllers and/or recorder outputs.

NOTICE!TOPAX® DX is equipped with a maximum of 8 power outputs. When switched on, the special functions of “total chlorine” and “conductivity” are already as-signed to 6 power outputs of the measured values.

If, additionally, the �0 mA controller outputs are configured, the maximum number of hardware outputs may be exceeded.

In this case the system is designed with internal priorities so that controller outputs and flocking pump outputs always receive priority. This means that no transmission of the measured values (0/4...�0 mA) is any longer available for temperature and con-ductivity.

When too many �0 mA outputs are selected, the disconnection sequence is:1. Temperature measurements�. Conductivity measurements

NOTICE!If the 0/4...20 mA continuous controller output is configured for an automatic controller, this can be manually adjusted to the actuator independently of the settings in the service menu - "recorder". It is possible to configure the 0...20 mA controller output and a 4...20 mA recorder output. It must be noticed that eventual changes in the „Service – Recorder menu“ will be reset after 20 mA outputs.

11.�Night�operationTOPAX® DX allows you to reduce use of Chlorine during night-time and/or after the closure of the SPA baths and pools. For this "economy operation mode", two timers can be defined. To automatically start the night-time mode, adjust these timers and assign them to the individual weekdays. These settings are ad-justed in the "service - timer menu ".

The desired value, which you need to reduce, can be adjusted in the main "night-time" menu. Moreover it is possible to reduce the capacity of the recirculation system. Adjust the parameters of the controller, based on the default settings for reduced recirculation power. Afterwards the night operation mode can be started. This can happen automatically when the timer is activated or when the night-time is directly switched on.

A second possibility is the activation of the night-time by an ex-ternal contact. This contact switches the night-time "ON" and "OFF" independently from the settings in the menu.

The night-time command is effective also for flocking.

12.�Economy�mode�-�DIN-contact�and�ECO-con-tactFor the "economy mode" a DIN - contact is defined. The DIN contact is generally used for the reduction of the recirculation capacity.

According to the DIN 19643, SPA baths and pools must follow and adhere to all hygiene auxiliary parameters. The active char-coal and the flocculation central dosage can be subsequently turned off."

parameter AreaFree chlorine: Minimum 0.30 and adjustable maximum between

0.60 and 1.�0 mg/l(adjustable, as the DIN Standards 19643 do not clearly indicate the upper limit value)

pH value: 6.5 – 7.6 pH

Redox: > 700 mV

Bonded chlorine: < 0,�0 mg/l

Parameter for DIN-Contact

For all measuring outputs the hysteresis must be known.

The DIN contact is closed when all the measured values are in the adjusted range.

NOTICE!If no total chlorine was measured and thus no bond-ed chlorine was determined, the contact can be used when bonded chlorine is proven to be within the DIN range by means of photometric analysis.

In the economy mode there are two variants:

12.1.�TOPAX®�DX�is�responsable�for�economy�modeDuring the initial configuration of the in- and outputs, the TOPAX DX asks for the "DIN-contact". For the DIN-contact, one of the options is "ECO-control". If this mode is switched on, the follow-ing functions are activated:

Save the "ECO - control" and enter the following menu to select the type of contact (relay or optocoupler). This contact is called "ECO - contact".

The DIN values are internally compared. If all DIN values are re-spected, the ECO-contact is set as "ECO-default mode" and will be activated every time when the night-time mode or timer is manually switched on.

Use the “night-time” menu (see chapter 16, menu �.4) to re-duce the recirculation capacity the lowered default value of the measurement "free chlorine". If you enter this lowest value as a percentage figure, all controller parameters will be adjusted accordingly to this lower percentage. Reduction rate up to 50% are admissible.

When set on night-time reduced operation mode with TOPAX® DX, the “Night-time operation” contact must be externally set to provide a feedback confirming that the recirculation capacity was actually reduced. The economy mode is effective only when a confirmation is given. Lack of compliance to DIN - parameters at the time of switching to night-time saving mode, will activate ongoing comparative timer check-up and the ECO–contact will be actually active as soon as the DIN-parameters are in place.

12.2.�TOPAX®�DX�controlled�DIN-contact�onlyShould the DIN-contact be switched on from outside, the in-strument will process the contact in the system but in this case TOPAX® will not be responsible for the performance. The „Night-time operation“ menu will have to be reset as well as the recir-culation capacity.


Chapter�13/14:�Control�of�the�flocking�pump�/�Log�book�function

13.�Control�of�the�flocking�pumpFor the control of the flocculation central pump different pos-sibilities can be selected.

Variant�1:�control�of�the�pump�proportionally�to�the�pure�water�flowInput signal 0/4...�0 mA

adjustment range 0...100 %

(Disturbance factor input)

Variant�2:�Control�of�the�metering�pump�by�direct�input.In the night operation mode the dosing pump can be operated for reduced flocculation capacity. The following operation modes can be selected in the "service" menu for the control of the flock-ing pump:• operation mode: off• Operation mode: "on" with setting of power output in %• Operation mode: "Night operation" with setting of separate

%-wise output capacity for day and night operation.• Operation mode: "flow-dependent" (disturbance variable)

with setting of power output in %• Operation mode: "flow-dependent” (disturbance value) and

night-time reduced service" with setting of power output into separate % for day-time and night-time.

The night operation mode is activated by the timers (setting of the timers in the service menu). The configuration of the output signal for the dosing pump is made in the configuration menu. The following outputs can be configured:• pulse frequency with optocoupler• pulse frequency with relay• pulse length with relay• Constant output 0/4...�0 mA• ON/OFF with relay

NOTICE!The night-time economy mode of the flocking pump does not depend on the DIN parameters!

14.�Log�book�functionThe following activities are stored in the logbook:• Configuration of the initial delivery with date and time• default configuration of date and time• Change of the automatic controller parameters (Xp, Tn,

Tv), basic load, delimitation, being, alarm parameters, and calibration data at start-up with date and time

• Change of the automatic controller parameters (Xp, Tn, Tv), basic load, delimitation, being, alarm parameters, and calibration data with date and time

• Configuration of the digital inputs

These data are stored on the MMC memory card and can be directly selected in the TOPAX® DX or with a PC.

The software version is stored as is and a file (* LOG) as text file and DATE (* DAT) as recorder file per day.

Furthermore, the configuration can be saved.

For the installation of the MMC memory card refer to chapter �1.

For the handling of the logbook, refer to chapter 16, menu 5.6 "Logbook".


Chapter�15:�Auto�setup

15.�Auto�setup�(First�system�self-setting)Menu for the automatic determination of the parameters of the automatic controller of free chlorine

(duration max. 4 hours and 33 minutes)

NOTICE!System self-setting starts when the actual value is stable near the desired value.

The pH value of the water basin must range between 6,8 and 7,3.

The current settings of the automatic controller parameters are shown in the self-setting menu. The process includes 4 main functions. Each function unit must run off in a certain time. If the new value is not reached within this time, an automatic calculation of the automatic controller data cannot be accomplished and the system self-setting process is stopped.

NOTICE!Do not alter the recirculation capacity during system self-setting.

Chapter�18/19:�Software�updates�/�Default�settings

18.�Software�updatesThe installation of new software for an update of the firmware or the languages is done with the help of the MMC card.

NOTICE!The MMC card must only be inserted when the pow-er supply is switched off (see chapter 21).

18.1�Firmware�update

IMPORTANT!For a firmware update, all software files on the MMC card must be deleted and replaced by the updated files.

Firmware update procedure:• Switch off the power supply of the TOPAX DX• Remove the MMC card• Connect the MMC card to a PC with a reading device• Delete the existing directories / files on the MMC card:

Directory „lang“ (language files) file „DX_D1--.EEP“ file „DX_M1--.EEP“ file´ „DX_D1--.HEX“ file „DX_M1--.HEX“

• Transfer the new files (software- and language files) to the MMC card via the PC

• Insert the MMC card in the TOPAX DX• Switch on the power supply of the TOPAX DX

When the operating voltage is supplied, the software is automati-cally installed and started on the TOPAX® DX DX.

NOTICE!For a firmware update to software version 1.13 or older, all settings of the TOPAX DX are overwritten. All settings of the TOPAX DX have to be written down before the update and be restored after the update.

18.2�Update�for�further�menu�languagesThe menu languages "German" and "English" are installed by default. They are automatically updated with a firmware update.

Further languages can be loaded at any time by transferring the respective language files for the software version installed on the TOPAX DX from the MMC card to the TOPAX DX (see chapter 4.8).

The language files can be found in the "lang" directory which is supplied together with the firmware update and have to be transferred from a PC to the MMC card (see 18.1). An overview of the languages, language files and software versions is given in chapter �6. Further languages are available on request.

IMPORTANT!Make sure that the correct software version for the language files is installed on the TOPAX DX!

19.�Default�settingsThe default configuration by the manufacturer includes the fol-lowing settings. The inputs are activated according to the part number.

• Y-Alarm (safety stop) works for all controllers and lasts 60 minutes

• Start-up lag time: 60 seconds• all measuring alarm values are deactivated• all special functions are deactivated

21.�Memory�cardThe memory card transfers and stores language data, firmware-updates and logfiles.

The data which is saved on the card can be transferred to a PC by means of a reading device. For the removal of the MMC card, the TOPAX® DX must be switched off definedly: press the "Switch Off" key in the "service-reset" menu. All controllers are set to an output capacity of "0%" and all unsaved data is saved on the MMC card. The TOPAX® DX can continue to operate without the card.

Fig. ��.1: Slot for the MMC Memory card on the display board. The card is inserted on the display circuit board in the front housing.

NOTICE!The memory card must only be inserted or removed when the device is voltage-free. Switch off the TOPAX DX on the "service-reset" menu (see chapter 16, menu 5.4).

On its website, the manufacturer provides the free software "TopReader" for the readout of the MMC with the recorder and configuration data.

NOTICE!Make sure that no additional data is saved on the MMC and that the saved data are not modified (data loss). The MMC must only be formatted in "FAT" format.


Chapter�22:�Troubleshooting�and�diagnostics
