Probable cause
Possible countermeasure
Check if the power supply
device conforms to the power
supply specifications.
Place the target to measure in
the measuring range.
Enter a TIMING signal.
Set the self-trigger level to an
appropriate value.
Identify the cause of the error
based on the error code
displayed on the sub-display
and take an appropriate
action.
• Check the target to mea-
sure and the measuring dis-
tance.
• Lowering the expose time
setting value may improve
the situation.
Set the average count
correctly.
Implement a vibration-control
countermeasure.
Clean the surface.
Check the fiber cable
connections.
Replace the fiber cable.
The Sensor Head needs to be
repaired.
Please contact an OMRON
branch or sales office.
For sensor head repair, return
as a set with the Calibration
ROM.
Perform air purging and so
forth to remove the droplets.
