LED/fault pattern Cause Measures
Yellow LED lights up, no object
in the path of the beam The sensing range distance is
too large Reduce the sensing range
Object is in the path of the
beam, yellow LED does not
light up Distance between the sensor
and the object is too long or
sensing range is set too short Increase the sensing range
No object in beam path, no
output signal Test input (Test) is not con‐
nected properly Check connection of the test
input. When using female cable
connectors with LED indicators,
make sure the test input is
assigned correspondingly.
8 Disassembly and disposal
The sensor must be disposed of in line with applicable country-specific regulations.
When disposing of them, you should try to recycle them (especially the precious met‐
als).
NOTE
Disposal of batteries, electric and electronic devices

•
WEEE: This symbol on the product, its package or in this document,
indicates that a product is subject to these regulations.
9 Maintenance
This SICK sensor is maintenance-free.
We do, however, recommend that the following activities are undertaken regularly:
• Clean the optical interfaces using a plastic cleaner, do not use acetone or methy‐
lated spirits.
• Check the fittings and plug connectors
No modifications may be made to devices.
Subject to change without notice. Specified product properties and technical data are
not written guarantees.
