The sensor is adjusted and ready for operation.
The Troubleshooting table indicates measures to be taken if the sensor stops working.

LED indicator/fault pattern
Yellow LED does not light up
even though the light beam is
aligned to the object and the
object is within the set sensing
range
Yellow LED flashes
Yellow LED lights up, no object
in the path of the beam
Object is in the path of the
beam, yellow LED does not
light up
The sensor must be disposed of according to the applicable country-specific regula‐
tions. Efforts should be made during the disposal process to recycle the constituent
materials (particularly precious metals).
Cause
No voltage or voltage below
the limit values
Voltage interruptions
Sensor is faulty
Sensor is still ready for oper‐
ation, but the operating condi‐
tions are not ideal
The sensing range distance is
too large
Distance between the sensor
and the object is too long or
sensing range is set too short
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
object / Clean the optical sur‐
faces / Check sensing range
and adjust if necessary
Reduce the sensing range
Reduce the sensing range
