1 Function and application
The position sensor SDAP is intended to be used for contactless detection of the
piston position of magnetically detectable drives in combination with the analogue
input module CTMM-S1-A-... (optional component of the VTEM Motion Terminal).
The SDAP position sensor records the magnetic field of the piston magnet and
continuously senses the piston movement in the sensing range.
An analogue current signal (4 ... 20 mA) is available as output signal.
Power supply is through the analogue input module CTMM-S1-A-....
2 Requirements for product use
 Only use the product in its original status, without any unauthorised modifica
tions.
 Use only in combination with the analogue input module CTMM-S1-A-... (optional
component of the VTEM Motion Terminal).
 Avoid having magnetic bodies near the position sensor. These could influence
the magnetic field and thereby the behaviour of the sensor.
 The product is intended for use in industrial environments. Interference suppres
sion measures may be required in residential areas.
Range of application and certifications
The information in this section, in combination with the UL and CSA marking on the
product, must be observed in order to be compliant with the certification condi
tions of Underwriters Laboratories Inc. (UL) for the USA and Canadian Standards
Association (CSA) for Canada.

3 Installation
Warning
Only use power sources which guarantee reliable electrical isolation of the oper
ating voltage in accordance with IEC/EN 60204-1. Observe also the general
requirements for PELV power circuits in accordance with IEC/EN 60204-1. Switch
power packs are permitted providing they guarantee reliable disconnection as
defined by EN 60950/VDE 0805.

Installation
1. Insert sensor into the T-slot of the drive or mounting kit.
2. Lightly clamp mounting screws.
3. Connect connecting cable to the input module.
4 Commissioning
Note
 Observe commissioning notes in the documentation of the VTEM Motion Terminal.
1. Switch on the operating and load voltage supply (UEL/SEN and UVAL) of the VTEM
Motion Terminal.
– The LEDs illuminate (dependent on the piston position).
– The device is ready for operation.
2. Move the piston into an end position of the application.
3. Remove the mounting screws of the sensor.
4. Push sensor in the direction of the piston until the red LED goes out.
5. Tighten mounting screws with tightening torque.

4.1 Analogue output function
The analogue output provides a displacement-proportional output signal
4...20 mA in the sensing range of the piston stroke.

LED indicator Description
Yellow Green Red
Green LED illuminated: Ready status (yellow: any, red: off).
– Analogue output function.
– Piston within the sensing range.
Green LED flashes for 3 seconds:
– When key is pressed. Meaning: Key has no function.
Red LED illuminated: status display.
– Piston outside the sensing range.

5 Disassembly
1. Switch off operating voltage.
2. Disconnect plug of the sensor from the input module.
3. Remove the mounting screws.
4. Pull sensor out of the T-slot of the drive or mounting kit.
