The yellow and green LEDs go out for approx. 1 s, then flash again alternately.

The yellow and green LEDs go out for approx. 1 s., after approx. 3 s the green 

LED is on�

The unit is in the operating mode. 

* The sensitivity can also be set in exactly the same way using the programming wire (pin 2 / 

WH). To activate the functions the programming wire is connected to L+ (pin 1 / BN) for PNP 

units or to L- (pin 3 / BU) for NPN units for the appropriate time. Feedback: If setting was not 

successful via the programming wire, the output will switch for 2 s. The unit then passes into 

the operating mode with the sensitivity being unchanged�

If the setting of the sensitivity is not possible (e.g. object signal and back

-

ground signal are about the same), the red LED flashes after step 3 for ap

-

prox. 2 s. The unit then passes into the operating mode with the sensitivity 

being unchanged� 

If the setting button is not activated for 15 minutes during the programming 

process, the unit passes automatically into the operating mode with the 

sensitivity being unchanged�
