LED indicator/fault pattern Cause Measures
3. Check electrical connections
Not all blue LEDs light up. a) Insufficient alignment
b) Contamination of the
optical surfaces
c) Particles in the light
beam
d) Distance between sen‐
sor and reflector is too
large
e) Reflector is not suitable
a) Check alignment
b) Cleaning of the optical
surfaces (sensor and
reflector).
c) Avoid contamination in
the air as far as possible
d) Check sensing range
e) SICK reflector is recom‐
mended
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).
10 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
