Set the sensitivity with object�

Press once�

 

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

Set the sensitivity without object�

Press once

 

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�

You can also proceed in reverse order: first setting without the object, then with the object�

* 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 for the appropriate 

time to L+ (pin 1 / BN) for PNP units or to L- (pin 3 / BU) for NPN units. Feedback: If setting 

was not successful via the programming wire, the output will switch for 2 s� The unit then 

reverts to the operating mode with the sensitivity 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 sen-

sitivity being unchanged�
