Subject to change without notice
LED indicator/fault pattern
No object in beam path, no out‐
put signal
Yellow LED flashes; if Alarm is
present then take note of the
corresponding output 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).
SICK sensors are maintenance-free.
We recommend doing the following regularly:
•
Clean the external lens surfaces
•
Check the screw connections and plug-in connections
No modifications may be made to devices.

DISASSEMBLY AND DISPOSAL
Cause
Test input (Test) is not con‐
nected properly
Sensor is still ready for opera‐
tion, but the operating condi‐
tions are not ideal

object surface (e.g., tape),

Measures
Check connection of the test
input. When using female
cable connectors with LED
indicators, make sure the test
input is assigned correspond‐
ingly.
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, see Figures 6-7 and
table
8. / Distance between
the sensor and the reflector is
too long
Reduce sensitivity or change
the position of the sensor
