Teach-in-procedure
With the teach-in-fuction the borders of the measurement range can be defined freely within the limits of the sensors
scanning range. Thus the analogue output gets a new characterisitc curve. The teach-in-procedure (decription on
page 2) can be accomplished manually with the bulit-in teach-button or equivalently by a teach-wire.
Within 5 minutes after power on the sensor can be teached with the help of the button at the sensor. After 5 minutes
the sensor does not react any longer to the button.
1. Press button, the LED turns on, if the sensor can still be teached
2. Press the button further 5 s until the LED begins to flash
3. Release button
4. Place a target in a position where the sensor should produce 0 V or 4 mA
5. Press button briefly (as a confirmation the LED flashes quickly), afterwards it continues to flash normally
6. Place a target in a position where the sensor should produce 10 V or 20 mA
7. Press button briefly (as a confirmation the LED flashes quickly), afterwards it turns of and flashes again briefly.
The sensor is now again ready for use.
If one of the 2 positions was outside of the measuring range, or if they were to closely together, the LED begins to
flash fastly. The teach-in procedure was not successful and has to be repeated. The external teach-in works equivalently
to the manual teach-in by applying + Vs to pin 2 (teach-in). By the teach-in-wire the sensors can be teached
any time without limit.
Reset to factory settings
1. Push the button. The red LED will turn on, if the sensor can be taught.
2. Hold down the button further 5 seconds. The LED will start to blink. DO NOT RELEASE the button now. Wait for
another 10 seconds. until the LED is ON without blinking.
3. Release button
Procedere can be carried out by the teachwire also.
Notes for user
• The intened use of the devices is discribed in the document. Others than
the described uses are not permitted or only after consulation with the manufacturer.
In particular the use of the devices is not permitted in applications,
in which security of persons depends on the function of the devices.
• The installation, start-up and the operation of the devices must be
made by a trained specialist. Here the valid regulations are relative to
consider:Accident prevention, Electromagnetic compatibility
• The technical data of electronics, in particular the ambient conditions and
connected loads, have to be considered.
