3 Sensitivity setting
Sensor not possible to be set: The sensor has been adjusted by the factory to provide maxi‐
mum sensitivity and is ready for operation.
4 Operation with marginal light reception
The sensor will provide a pre-failure notification by flashing the orange LED indicator when
operating with marginal light reception. This may be the result of incorrect alignment or
contaminated optical surface(s). The sensor may be equipped with a Health or Alarm out‐
put, which provide a discrete signal when the sensor is operating in the marginal condition.
Refer to
table 3 for additional detail on Health/Alarm output operation.
8 Troubleshooting
The Troubleshooting table indicates measures to be taken if the sensor stops working.
Table 6: Troubleshooting
LED indicator/fault pattern Cause Measures
Yellow LED does not light up
even though the sender 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 /
Health is present then take
note of the corresponding out‐
put signal Sensor is still ready for opera‐
tion, but the operating condi‐
tions are not ideal Check the operating condi‐
tions: Fully align the sender
and receiver / Clean the opti‐
cal surfaces
