Cause
IO-Link communication
1. Change of the configuration
2. Short-circuit
a) Insufficient alignment
b) Contamination of the opti‐
cal surfaces
c) Particles in the light beam
d) Distance between sensor
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 /
reflector is not suitable / Front
screen and/or reflector is con‐
taminated.

1. Adjustment of the configura‐
tion
2. Check electrical connections
a) Check alignment
b) Cleaning of the optical sur‐
faces (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
