When there is material in front of the sensor, the output is in the reference position OFF. When the material dis-
appears, the timer, starts, and the output will change to ONafter the set delay.
The status of the sensor is indicated with a yellow LED.

The sensor sensitivity and delayed disconnection can be adjusted on two trimmers.
