SICK WTB4F SingleLine - Process Data Structure; Troubleshooting

NOTE
Do not operate the teach-in button using sharp objects.
Please refer to the enclosed operating instructions for the IO-Link photoelectric sensor
for information about adjusting the IO-Link sensing range.
The sensor is adjusted and ready for operation.
WTx4Fx-xxxxxxA0Zxx:
Sensor which it is not possible to set: the sensor is adjusted and ready for operation.

7 Troubleshooting
The Troubleshooting table indicates measures to be taken if the sensor stops working.
Table 14: Troubleshooting
LED/fault pattern Cause Measures
Green LED flashes IO-Link communication None
Switching outputs do not
behave in accordance with
table 6
1. IO-Link communication
2. Change of the configuration
3. Short-circuit
1. None
2. Adjustment of the configura‐
tion
3. Check electrical connections
Yellow LED lights up, no object
in the path of the beam
The sensing range distance is
too large
Reduce the sensing range
