LED indicator/fault pattern Cause Measures
Yellow LED lights up, no object
in the path of the beam Remission capability of the
background is excessive Check changes to the back‐
ground. Reduce the sensitivity
of the sensor or use sensors
with background suppression
Object is in the path of the
beam, yellow LED does not
light up Sensitivity is set too low or dis‐
tance between the sensor and
the object is too long Increase the sensing range,
take note of the distance
between the sensor and the
background
Object is in the path of the
beam, yellow LED does not
light up Remission capability of the
object is insufficient Increase the sensing range,
take note of the distance
between the sensor and the
background
8 Disassembly and disposal
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).
9 Maintenance
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.
