Figure 6: Detection
The Troubleshooting table indicates which measures are to be taken if the sensor stops
working.

LED indicator/fault pattern
Green LED does not light up
Green LED does not light up
Green LED does not light up
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
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 sensor
and the background is too
short
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 / Readjust the sensitiv‐
ity (potentiometer) / Check
sensing range and adjust if
necessary, see figure 3,
page 8
Reduce the sensing range,
see figure 3
increase the sensing range,
take note of the distance
between the sensor and the
background, see figure 3
