Cause
No voltage or voltage below
the limit values
Voltage interruptions
Sensor is faulty
SenderOff Input is not con‐
nected properly
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.
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
See the note on connecting
the SenderOff-Input.
At low ambient temperatures,
wait until the sensor has
warmed up. Ensure the sensor
cools down at excessively high
ambient temperatures.
Check the teach-in mode
Reduce the sensing range
Increase the sensing range
