7.3 Setting
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: 270°). 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.
8 Troubleshooting
The Troubleshooting table indicates measures to be taken if the sensor stops working.

Table 4: Troubleshooting
LED indicator/fault pattern Cause Measures
Green LED does not light up No voltage or voltage below
the limit values Check the power supply,
check all electrical connec‐
tions (cables and plug connec‐
tions)
Green LED does not light up Voltage interruptions Ensure there is a stable power
supply without interruptions
Green LED does not light up Sensor is faulty If the power supply is OK,
replace the sensor
Yellow LED flashes Sensor is still ready for oper‐
ation, but the operating condi‐
tions are not ideal Check the operating condi‐
tions: Fully align the beam
of light (light spot) with the
reflector / Clean the optical
surfaces (sensor and reflec‐
tor) / Readjust the sensitiv‐
ity (potentiometer) / If the
potentiometer is set to the
