position and conclude the teach event
The teach event ends after 2s, the sensor detects the object at this
position and the LED is on.
If the object is removed, the LED must be switched off.
Teaching error
If the object is located outside of the scanning range during the teach event, a teaching error occurs.
The LED flashes quickly and the switching output is reset to the factory setting (switching point at the max. scanning range).
Resetting the sensor to factory setting
Teach-in input PIN 2
Restoring the factory setting
Locking the teach input
The sensor automatically locks the teach input after either 5 min. after power-on or 5min. after the last teach event is ended.
A new teach event is only possible after disconnecting the sensor from voltage.
If the Teach-IN input is not used,
it must be connected to GND!
