LED indicator/fault pattern
Green LED flashes
Switching outputs do not
behave in accordance with
figure X
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
The sensor must be disposed of according to the applicable country-specific regula‐
tions. Efforts should be made during the disposal process to recycle the constituent
materials (particularly precious metals).

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
