measuring range adjustment (teach-in)
1. Connect voltage supply and analog output, the teach-in process must take place within 5 minutes time.
2. Connect the teach-contact (white wire / PIN 2) with +UBfor until the yellow and the red LED are flashing alter-
nating. After this open the connection.
3. The LED flashes red. Bring the object to be detected into the position where the analog output should output
0V. Afterwards connect the teach-contact shortly (< 1sec) with +UB.
4. The LED flashes yellow. Bring the object to be detected into the position where the analog output should out-
put 10V. Afterwards connect the teach-contact shortly (< 1sec) with +UB.
5. The sensor confirms the successful teach-process by flashing of both LEDs for 2sec.
