LED indicator/fault pattern
Cause
Measures
Green LED does not light up or
flickers
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
Q-LED flashes yellow
Sensor is still ready for opera‐
tion, but the operating condi‐
tions are not ideal
Cleaning of the optical sur‐
faces. Perform teach-in again.
One of the two Q-LEDs do not
light up
The respective light beam is
interrupted
Remove object from light
beam
The optical surfaces are cont‐
aminated
Cleaning of the optical sur‐
faces. Perform teach-in again.
