5.4 Troubleshooting
Error Possible cause Elimination
Warning Warning signal • Reduce distance between sensor and object
• Adjust angle of sensor to object
Undervoltage • Increase voltage supply to min. 18VDC
Error Short circuit • Check the electrical wiring and eliminate the
short circuit
Temperature error • Disconnect the sensor from the supply voltage
and allow it to cool
• Mount the mounting bracket as a heat sink
• Reduce load on outputs
Device error • Disconnect the sensor from the supply voltage
and restart it
• Replace the sensor
Via IO-Link, it is possible to identify the respective causes precisely by means of condition monitoring. Fur-
ther diagnosis functions and status messages are also possible. See section Condition Monitoring/Process
Data [}37].
