The Troubleshooting table indicates measures to be taken if the sensor stops working.
LED indicator/fault pattern
Green LED flashes
Switching outputs do not
behave in accordance with
table 3, page 7 and see
table 4, page 8
The blue LEDs are very close
together
Yellow LED flashes
Yellow LED does not light up
even though the light band is
aligned to the reflector and
there is no object in the path of
the beam

Cause
IO-Link communication
a) IO-Link communication
see
b) Change of the configuration
c) Short-circuit
Front screen and/or reflector
is contaminated.
Distance between sensor and
reflector is too large / light
band is not completely aligned
to the reflector / reflector is
not suitable / front screen
and/or reflector is contami‐
nated
No voltage or voltage below
the limit values
Voltage interruptions
Sensor is faulty

Measures
None
a) None
b) Adjustment of the configu‐
ration
c) Check electrical connec‐
tions
Cleaning of the optical sur‐
faces (sensor and reflector).
Check sensing range / check
alignment / SICK reflector is
recommended / Cleaning of
the optical surfaces (sensor
and reflector)
Check the power supply,
check all electrical connec‐
tions (cables and plug connec‐
tions)
Ensure there is a stable power
supply without interruptions
If the power supply is OK,
replace the sensor
