LED indicator/fault pattern
Yellow LED does not light up
even though the light beam is
aligned to the reflector and
there is no object in the path of
the beam
Yellow LED flashes; if Alarm /
Health is present then take
note of the corresponding out‐
put signal
Signal interruptions when
object is detected
The sensor must be disposed of according to the applicable country-specific regula‐
tions. Efforts should be made during the disposal process to recycle the constituent
materials (particularly precious metals).

Subject to change without notice. Specified product properties and technical data are
not written guarantees.
Cause
No voltage or voltage below
the limit values
Voltage interruptions
Sensor is faulty
Sensor is still ready for opera‐
tion, but the operating condi‐
tions are not ideal
Depolarizing property of the
object surface (e.g., tape),
reflection
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 the operating condi‐
tions: Fully align the beam of
light (light spot) with the
object / Clean the optical sur‐
faces
Change the position of the
sensor
