Table 3: Adjustment sensing range
The sensor is adjusted and ready for operation.
The Troubleshooting table indicates measures to be taken if the sensor stops working.
Table 4: Troubleshooting
LED/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
Object is in the path of the
beam, yellow LED does not
light up
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
Excessive background remis‐
sion
Sensitivity is set too low or dis‐
tance between the sensor and
the object is too long
Remission capability of the
object is insufficient
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
Check changes to the back‐
ground. Reduce the sensitivity
of the sensor or use sensors
with background suppression
Increase the sensing range,
take note of the distance
between the sensor and the
background
Increase the sensing range,
take note of the distance
between the sensor and the
background
