Object is in the path of the
beam, yellow LED does not

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).
TABLE FAULT DIAGNOSIS
Cause /
Cause
No voltage or voltage below
the limit values
Voltage interruptions
Sensor is faulty
Sensor is still ready for opera‐
tion, but the operating condi‐
tions are not ideal
Distance between the sen‐
sor and the background is too
short
Distance between the sensor
and the object is too long or
sensing range is set too
short
Measures /
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 . / Readjust the sensitiv‐
ity (potentiometer) / Check
sensing range and adjust if
necessary; see graphic F.
Reduce the sensing range,
see graphic F
Increase the sensing range,
see graphic F
