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.

is aligned to the reflector and
there is no object in the path of
the beam

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
Check the operating condi‐
tions: Fully align the beam
of light (light spot) with the
reflector. / Clean the optical
surfaces (sensor and reflec‐
tor) / If the potentiometer is
set to the max. sensitivity:
Reduce the distance between
the sensor and the reflector,
and check the reflector type /
