- Short-circuit / Overcurrent
- Sensor is not connected prop‐
erly
- Disconnect sensor from the
power network
- Check pin assignment
- Reconnect sensor
- Check the current at the
switching output

Programmed contrast or con‐
trast difference is not sufficient
for stable contrast detection.
- Clean sensor
- Readjust the sensor
- Check the application condi‐
tions
- Restart teach process
- Increase contrast difference
