Disassembly and disposal

Subject to change without notice
Sensitivity setting
Sensor which it is not possible to set: The sensor is adjusted and ready for operation.
The sensitivity is adjusted with the potentiometer (type: 5-turn). Clockwise rotation:
operating reserve increased; counterclockwise rotation: operating reserve reduced. We
recommend setting the potentiometer to "Maximum". A lower operating reserve may be
necessary for depolarizing surfaces.
The sensor is adjusted and ready for operation.
The Troubleshooting table indicates measures to be taken if the sensor stops working.

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
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).
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
COMMISSIONING
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
reflector. / Clean the optical
surfaces (sensor and reflec‐
tor) / If the potentiometer is
set to the max. sensitivity:
Reduce the distance between
the sensor and the reflector,
and check the reflector type /
Reflector is not suitable for
the application in question
(we recommend only using
SICK reflectors) / Check sens‐
ing range and adjust if neces‐
sary / Distance between the
sensor and the reflector is too
long
Reduce sensitivity or change
the position of the sensor
