3 Sensitivity setting
Sensor with potentiometer: open the sensor cover and protective hood, make sure that no
dirt has gotten into the sensor.
The sensitivity is adjusted with the potentiometer (type: without stop). Clockwise rotation:
operating reserve increased; counterclockwise rotation: operating reserve reduced. We rec‐
ommend setting the potentiometer to "Maximum". A lower operating reserve may be nec‐
essary for depolarizing surfaces.
The sensor is adjusted and ready for operation.
4 Time function setting

1 = relay active. Time delay selector switch can be set on the device according to
table 1.
