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 object and the
object is within the set sensing
range 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 opera‐
tion, but the operating condi‐
tions are not ideal 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
Yellow LED lights up, no object
in the path of the beam Excessive background remis‐
sion Check changes to the back‐
ground. Reduce the sensitivity
of the sensor or use sensors
with background suppression
Object is in the path of the
beam, yellow LED does not
light up Sensitivity is set too low or dis‐
tance between the sensor and
the object is too long Increase the sensing range,
take note of the distance
between the sensor and the
background
Object is in the path of the
beam, yellow LED does not
light up Remission capability of the
object is insufficient Increase the sensing range,
take note of the distance
between the sensor and the
background
9 Disassembly and disposal
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).
