The Troubleshooting table indicates measures to be taken if the sensor stops working.
Table 6: Troubleshooting
LED/fault pattern
Green LED flashes
Switching outputs do not
behave in accordance with
table 5
Yellow LED lights up, no object
in the path of the beam
Object is in the path of the
beam, yellow LED does not
light up
No object in beam path, no
output signal
Notes on malfunctions can be found in the service data.
Details of the available service data can be found in the detailed IO-Link description:

Cause
IO-Link communication
1. IO-Link communication
2. Change of the configuration
3. Short-circuit
The sensing range distance is
too large
Distance between the sensor
and the object is too long or
sensing range is set too short
Test input (Test) is not con‐
nected properly

connectors with LED indicators,
make sure the test input is
assigned correspondingly.
