Troubleshooting
The Troubleshooting table indicates measures to be taken if the sensor stops working.
6.2
Table: Fault diagnosis
LED indicator/fault pattern
Cause
Measures
Green LED does not light up
No voltage or voltage below
the limit values
Check the power supply,
check all electrical connec‐
tions (cables and plug connec‐
tions)
Green LED does not light up
Voltage interruptions
Ensure there is a stable power
supply without interruptions
Green LED does not light up
Sensor is faulty
If the power supply is OK,
replace the sensor
Green LED lights up, no output
signal when object is detected
SenderOff Input is not con‐
nected properly
See the note on connecting
the SenderOff-Input.
Yellow LEDs flash at the same
time
The sensor is not ready for
operation. The sensor will be
in the warming-up phase at
low ambient temperatures.
The sensor will have shut
down at excessively high
ambient temperatures.
At low ambient temperatures,
wait until the sensor has
warmed up. Ensure the sensor
cools down at excessively high
ambient temperatures.
Yellow LED flashes (only briefly) Teach-in mode
Check the teach-in mode
rechte gelbe LED leuchtet, kein
Objekt im Strahlengang
Distance between the sensor
and the background is too
short
Reduce the sensing range
Object is in the path of the
beam, yellow LED does not
light up
Distance between the sensor
and the object is too long or
sensing range is set too short
Increase the sensing range
