Troubleshooting
The Troubleshooting table indicates measures to be taken if the sensor stops working.

Table: Fault diagnosis
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 lights up, no object
in the path of the beam
Distance between the sensor
and the background is too
short
Reduce the sensing range,
see graphic F
Object is in the path of the
beam, yellow LED does not
light up
Distance between the sensor
and the object is too long or
sensing range is set too short
Increase the sensing range,
see graphic F
