7.3 Settings
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”.
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
Yellow LED does not light up
even though the light beam
is aligned to the receiver and
there is no object in the path of
the beam
No voltage or voltage below
the limit values
Check the power supply,
check all electrical connec‐
tions (cables and plug connec‐
tions)
Voltage interruptions Ensure there is a stable power
supply without interruptions
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
receiver. / Clean the optical
surfaces / If the potentiom‐
eter is set to the max. sen‐
sitivity: Reduce the distance
