8 Troubleshooting
8.1 Possible errors during commissioning
Table 15: Troubleshooting during commissioning
Display, error situation Cause Measure
•
“Err” flashes
•
Q LED (yellow) flashes
•
Short-circuit mes‐
sage/overcurrent message
•
Sensor is not connected
properly
•
Disconnect sensor from the
power network
•
Check pin assignment
•
Reconnect sensor
•
Check the current at the
switching output
No change to the segment
display in mounting feedback
mode
•
Distance between the sen‐
sor and the background is
too large or too small
•
Light emission (optics) is
dirty
•
Clean sensor
•
Check the application con‐
ditions
•
Restart adjustment process
After the teach process
•
“Err” flashes
•
Q LED (yellow) and TCH
LED (yellow) flash
•
No signal change at the
switching output for object
detection
Taught-in contrast or contrast
difference is not sufficient for
stable contrast detection.
•
Readjust sensor
•
Clean sensor
•
Check the application con‐
ditions
•
Restart teach process
•
Increase contrast difference
8.2 Possible errors during operation
Table 16: Troubleshooting during operation
Display, error situation Cause Measure
Busy Sensor is undergoing an inter‐
nal process.
Wait until the process has fin‐
ished.
No switching output any more
•
Distance or angle to mate‐
rial not consistent
•
Light emission (optics) is
dirty
•
Manual switching thresh‐
old set incorrectly
•
Clean sensor
•
Readjust sensor
•
Check parameter settings
•
Perform teach process
again
