Instruction Manual

Product Description

The purpose of position sensors is to transform position of a linear and guided movement into an electrical signal. Specifications of measuring range, environment, handling and connections as specified in the catalog, must be followed.The catalog is part of this instruction manual. If the catalog is not available it may be requested by stating the respective model number.

The Operating PrincipleLinear motion of the measuring cable (flexible stainless steel) is converted into rotation by means of a precision cable drum. A spring motor provides torque for the cable retraction. Special design assures precise and repro-ducible winding of the measuring cable.Cable extraction or retraction is transformed into an electrical signal. Depending on application different sensing elements are used. Optional: Subsequent signal conditioners convert the signal of the sen-sing element into voltage, current, or digital pulses suitable for standard interfaces.

Measurement Signal and Range

Instruction Manual

Installation (continued)

Installation position

Cable travel should only be axial to the cable outlet - no misalignment is allowed.Cable misalignment shortens service life of sensor and causes error in measurement. Warranty will not be granted for damage caused by misalignment.

If cable travel axial to the cable outlet is not possible, the cable guide wheel SR (accessories) must be used in order to turn the cable.

For special applications extension cables with clips on both ends are available.

Fitting the sensorDepending upon the sensor model, drillings in the base plate, threads or T-slots in the sensor housing enable attachment of the sensor. Dimensions required are listed in the catalog.

Cable attachment deviceFor fastening the cable clip the following solutions are available. For example:

a) Set screw M5: Standard fixing. (Allen screw)b) Attachment head GK1/GK: Fast cable attachment, easy to (accessory) remove.c) Magnetic clamp MAG1: An easy way to fasten the cable to (accessory) ferromagnetic materials.

The mounting of the M connection is made with a through hole and a M nut. Note: Do not screw the M connection itself into a stationary object, otherwise the measuring cable will be twisted!

Cable clip attachmentWhen fastening the cable clip take notice of the chapter Installation / Pre-cautions (page ).

This prevents cable from damage, soiling and manipulation.

Soaking of liquids into the cable out-let is impossible, concentration of condensing water will be avoided.

This prevents sensor from bending and damage.

Covered or shielded travel of cable is preferred.

Cable outlet is preferred pointing downwards.

Fit sensor on plain base or use three-point mounting on uneven surfaces.

Calibration (ISO9001)

Electromagnetic Compatibility (EMC)

Repair and Disposal

The recommended calibration interval is 1 year.

Test protocol and traceable calibration certificate (ISO9001) is available on request.

The electromagnetic compatibility depends on wiring practice. Recommen-ded wiring:

Use shielded twisted pair sensor cable.Ground shield single ended at switch cabinet. Connect shield direct-ly before or at cable inlet of switch cabinet by low impedance ground cable bond. On delivery of preassembled sensor cables the shield is not connected to the sensor housing.Keep sensor signal well separated from power wiring e.g. AC wiring, motor or relay. Use separate conduit or ducts for each.

If application includes highly electromagnetic interference emitting equipment like switch converter drives additional measures are recommended:

Use a twisted pair cable, shielded per pair and common.Use shielded conduits or ducts connected to ground potential.

Sensors and accessories have to be repaired and adjusted at ASM in Moosinning.

In order to avoid risk of injury and improper handling do not try to repair. No warranty or liability will be granted for opened sensors.

Disposal: Send metal parts for recycling!

Warning Note:If the GND (0V) signal connection is missing the signals DATA and DATA will rise to the potential of the excitation voltage. This may damage the input circuit of the subsequent processing unit if this unit is not connected with galvanic isolation (e.g. opto-coupling devices). This will happen especially when the mating connector is disconnected while power is on.

The sensing device of the ADSI is a precision potentiometer. The position in-formation is given by an analog/digital converter output serialized as a data word. Data transmission takes place by means of the signals CLOCK and DATA. The processing unit (PLC, Micro- computer) sends pulse sequences which clock the data transmission with the required transfer rate. With the first falling edge of a pulse sequence the position of the sensor is recorded and stored. The following rising edges control the bit-by-bit A/D conversion, encoding and output of the data word. After a delay time the next new position information will be transmitted.

Notes: Download of the manual and the configuration file of the encoder at the ASM website www.asm-sensor.com in the “Downloads” section (hcanop_de_en.zip).The encoder parameters must be set before operation!In the subsequent electronics the 1 bit LSB resolution of the data sheet must be considered as a scaling factor.If the encoder is set to another single turn resolution, the scaling factor is the result of the resolution of the cable drum of the WS sensor per revolution and the resoltution of the encoder.Example: WS19KT-1000 with angle encoder 1 bit/revolution, distance/revolution 00 mmScaling factor: 00 mm / ^1 = 00 mm / 819 = 0,0 mm / Bit (= LSB resolution)

Appendix – Output Information

Voltage divider R1KPotentiometer

The output signal is the ratiometric voltage of a potentiometer. The poten-tiometer is supplied by a reference voltage source. The ratio of the output signal to the reference voltage is proportional to the measuring cable ex-tension. For optimum performance of the sensor 9% (% to 9%) of the potentiometers total span is used for the specified measurement range. Provision for setting the electrical zero and voltage amplification must be made in the subsequent signal processing circuit. To avoid linearity error the output load should be as low as possible. Therefore the input impedance of the processing circuit must be ≥10 MΩ.

(Reference voltage)Suggested output circuit

Voltage output 0 ... 10 V (10V)

This output signal is 0 to 10 Volts proportional to the measuring cable ex-tension of 0 to 100%. This is an industry standard output which is widely accepted because of its simple signal processing and suitability for all display, recording and automation systems. For analog signal processing the voltage output is the proven best choice, e.g. for Waveform Analyzers, Data Loggers and for analog and digital Oscilloscopes. ASM´s 0...10 V output supports a wide range of excitation voltages and is well protected against electromagnetic interference.

Current output4 ... 20 mA (420A) ( wire)

This output signal is a to 0 mA current loop proportional to the mea-suring cable extension of 0 to 100%. It is an industry standard two-wire system for the transmission of measured values. The current loop is both measurement signal and sensor excitation current. The measured value is represented as a voltage drop across a load resistor RM. The current is constant and the signal cable resistance (RL) will have no effect on the measured value. Therefore long signal cables can be used, limited only by the cable resistance (impedance). Signal cable disconnection or failure can be detected by a 0 mA current signal.


RL (cable resistance)

Current output4 ... 20 mA (420T) ( wire)

This output signal is a to 0 mA current loop (alternatively 0 to 0 mA) pro-portional to the measuring cable extension of 0 to 100%. The 3 wire current loop system is especially resistant to electromagnetic interference because of the separate sensor excitation and the low resistance (impedance) of the signal processing electronics. As in the two-wire system the measured value is represented as a voltage drop across a load resistor RM and is, within limits, independent of the cable resistance (impedance).

Signal conditio-ner PMUV/PMUI, adjustableVoltage or current output

The signal conditioner PMU has voltage or current output. The minimum and maximum output values can be adjusted by using the two push-buttons Offset und Gain.Setting up procedure: Move the sensor to the required start (zero) position and depress and release the Offset pushbutton. The signal conditioner will be adjusted automatically to the 0 V or 4 mA output level. Using a similar procedure, move the sensor to the full scale position, depress and release the Gain pushbutton, and the signal conditioner will automatically be ad-justed for full scale output.
