LED indicator/fault pattern
Yellow LED does not light up
even though the light beam is
aligned to the receiver and
there is no object in the path of
the beam
No object in beam path, no out‐
put signal
Yellow LED flashes; if Alarm is
present then take note of the
corresponding output signal
0.5 ... 10 sec.
0.5 ... 10 sec.
0.5 ... 10 sec.
Cause
No voltage or voltage below
the limit values
Voltage interruptions
Sensor is faulty
Test input (Test) is not con‐
nected properly
Sensor is still ready for opera‐
tion, but the operating condi‐
tions are not ideal
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 connection of the test
input. When using female
cable connectors with LED
indicators, make sure the test
input is assigned correspond‐
ingly.
Check operating conditions:
align light beam (light stop)
completely on the receiver/
cleaning of optical surfaces /if
potentiometer is set to max.
sensitivity: reduce distance
between sender and
receiver /Check sensing range
and adjust if necessary.
