Use
see table 2, page 8
to check the function. If the switching output fails to behave
in accordance with the table, check the application conditions. See section Fault diag‐
nosis.
Sensing range setting
Sensor which it is not possible to set: The sensor is adjusted and ready for operation.
Table 3: Sensing range setting
The Troubleshooting table indicates measures to be taken if the sensor stops working.

LED/fault pattern
Yellow LED does not light up
even though the light beam is
aligned to the object and the
object is within the set sensing
range
Yellow LED lights up, no object
in the path of the beam

Cause
No voltage or voltage below
the limit values
Voltage interruptions
Sensor is faulty
Excessive background remis‐
sion
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 changes to the back‐
ground. Reduce the sensitivity
of the sensor or use sensors
with background suppression
