8 Troubleshooting
The Troubleshooting table indicates measures to be taken if the sensor stops working.
LED indicator/fault pattern Cause Measures
Green LED flashes IO-Link communication None
Switching outputs do not
behave in accordance with see
table 3, page 7 and see
table 4, page 8
a) IO-Link communication
b) Change of the configuration
c) Short-circuit
a) None
b) Adjustment of the configu‐
ration
c) Check electrical connec‐
tions
The blue LEDs are very close
together
Front screen and/or reflector
is contaminated.
Cleaning of the optical sur‐
faces (sensor and reflector).
Yellow LED flashes 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
Check sensing range / check
alignment / SICK reflector is
recommended / Cleaning of
the optical surfaces (sensor
and reflector)
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
No voltage or voltage below
the limit values
Check the power supply,
check all electrical connec‐
tions (cables and plug connec‐
tions)
Voltage interruptions Ensure there is a stable power
supply without interruptions
Sensor is faulty If the power supply is OK,
replace the sensor
