LED indicator/fault pattern Cause Measures
Yellow LED flashes Distance between sensor
and reflector is too large /
light beam is not completely
aligned to the reflector /
reflector is not suitable / Front
screen and/or reflector is con‐
taminated.
Check sensing range / check
alignment / SICK reflector is
recommended / Cleaning of
the optical surfaces (sensor
and reflector).
9 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).
NOTE
Disposal of batteries, electric and electronic devices
•
According to international directives, batteries, accumulators and electrical or
electronic devices must not be disposed of in general waste.
•
The owner is obliged by law to return this devices at the end of their life to the
respective public collection points.
•
WEEE: This symbol on the product, its package or in this document,
indicates that a product is subject to these regulations.
10 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.
