8.1 Possible errors during commissioning
Table 13: Troubleshooting during commissioning
Display, error situation Cause Measure
•
“Err” flashes
•
Q LED (yellow) flashes
•
Short-circuit message/
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 dis‐
play in Mounting feedback
mode
•
Distance between the
sensor and the back‐
ground is too large or too
small
•
Light emission (optics) is
dirty
•
Clean sensor
•
Check the application
conditions
•
Restart adjustment proc‐
ess
After the teach process
•
“Err” flashes
•
Q LED (yellow) and TCH
LED (yellow) flash
•
No signal change at the
switching output for
object detection
Programmed contrast or con‐
trast difference is not suffi‐
cient for stable contrast detec‐
tion.
•
Readjust sensor
•
Clean sensor
•
Check the application
conditions
•
Restart teach process
•
Increase contrast differ‐
ence

Possible errors during operation
Table 14: 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
material not consistent
•
Light emission (optics) is
dirty
•
Manual switching
threshold set incorrectly
•
Clean sensor
•
Readjust sensor
•
Check parameter settings
•
Perform teach process
again
