Cause
1. Change of the configuration
2. Short-circuit
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.
Test input (Test) is not con‐
nected properly
Measures
1. Adjustment of the configura‐
tion
2. Check electrical connections
Check sensing range / check
alignment / SICK reflector is
recommended / Cleaning of
the optical surfaces (sensor
and reflector).
Check connection of the test
input. When using female cable
connectors with LED indicators,
make sure the test input is
assigned correspondingly.
