9 Troubleshooting
The Troubleshooting table indicates measures to be taken if the sensor stops working.
Table 20: Troubleshooting
LED/fault pattern Cause Measures
Yellow LED does not light up
even though the light beam
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
Green LED flashes IO-Link communication -
Switching outputs do not
behave in accordance with
table 5
IO-Link communication None
Change of the configuration Adjustment of the configura‐
tion
Short-circuit Check electrical connections
The blue LEDs are very close
together
Front screen and/or reflector
is contaminated.
Cleaning of the optical surfa‐
ces (sensor and reflector).
Yellow LED flashes Distance between sensor
and reflector is too large /
light beam is not completely
aligned to the reflector /
Check the operating condi‐
tions: Fully align the beam
of light (light spot) with the
reflector. / Clean the optical
