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

The sensor must be disposed of in line with applicable country-specific regulations.
When disposing of them, you should try to recycle them (especially the precious met‐
als).
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
Depolarizing property of the
object surface (e.g., tape),
reflection
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) / Readjust the sensitiv‐
ity (potentiometer) / If the
potentiometer is set to the
max. sensitivity: Reduce the
distance between the sensor
and the reflector, and check
the reflector type / Reflector
is not suitable for the appli‐
cation in question (we recom‐
mend only using SICK reflec‐
tors)/ Check sensing range
and adjust if necessary, see
table 3. / Distance between
the sensor and the reflector is
too long
Reduce sensitivity or change
the position of the sensor
