blue Recommended sensing range for the best performance
Sensitivity setting
Sensor which it is not possible to set: The sensor is adjusted and ready for operation.
The sensitivity is adjusted with the potentiometer (type: 5-turn). Clockwise rotation:
operating reserve increased; counterclockwise rotation: operating reserve reduced. We
recommend setting the potentiometer to "Maximum". A lower operating reserve may be
necessary for depolarizing surfaces.
The sensor is adjusted and ready for operation.
The Troubleshooting table indicates measures to be taken if the sensor stops working.

Measures
Check the power supply,
check all electrical connec‐
tions (cables and plug connec‐
tions)
Ensure there is a stable power
supply without interruptions
If the power supply is OK,
replace the sensor
