The Troubleshooting table indicates measures to be taken if the sensor stops working.
LED/fault pattern
WEO:Green LED flashes
Switching outputs do not
behave in accordance with
table 5
Not all blue LEDs light up.
No object in beam path, no
output signal
Yellow LED flashes

Cause
IO-Link communication
1. Change of the configuration
2. Short-circuit
a) Insufficient alignment
b) Contamination of the opti‐
cal surfaces
c) Particles in the light beam
d) Distance between sender
(WS) and receiver (WE) is
too large
Test input (Test) is not con‐
nected properly
Distance between sender
(WS) and receiver (WE) is too
large / Beam of WS is not
completely on WE or WE is not
aligned to WS

1. Adjustment of the configura‐
tion
2. Check electrical connections
a) Check alignment
b) Cleaning of the optical sur‐
faces.
c) Avoid contamination in the
air as far as possible
d) Check sensing range
Check connection of the test
input. When using female cable
connectors with LED indicators,
make sure the test input is
assigned correspondingly.
Check sensing range, see
figure 13
Check alignment
