Cause
IO-Link communication
1. IO-Link communication
2. Change of the configuration
3. Short-circuit
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
Distance between sensor and
reflector is too large / light
beam is not completely
aligned to the reflector /

Measures
None
1. None
2. Adjustment of the configura‐
tion
3. Check electrical connections
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
Check sensing range / check
alignment / SICK reflector is
recommended / Cleaning of
the optical surfaces (sensor
and reflector).
