WSE24-2xx4x: with static front-screen heating for use in environments with gradual
temperature changes within the +5 °C ... +15 °C range.
WS/WE24-2V530S01: M12 male connector, 5-pin, glass front screen, dynamic power
heating on the rear side of the glass, current consumption: sender 150 mA, receiver
140 mA. The dynamic power heating is automatically switched on and off depending on
the ambient temperature (23-26 °C). For the use of quick temperature changes in the
range of <0 °C…+10 °C

Troubleshooting
The Troubleshooting table indicates measures to be taken if the sensor stops working.
Table 9: Troubleshooting
LED indicator/fault pattern
Cause
Measures
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 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
No object in beam path, no out‐
put signal
Test input (Test) is not con‐
nected properly
Check connection of the test
input. When using female
cable connectors with LED
indicators, make sure the test
input is assigned correspond‐
ingly.
Yellow LED flashes; if Alarm is
present then take note of the
corresponding output signal
Sensor is still ready for opera‐
tion, but the operating condi‐
tions are not ideal
Check operating conditions:
align light beam (light stop)
completely on the receiver/
cleaning of optical surfaces /if
potentiometer is set to max.
