If an alarm occurs,
check the error
code of alarm
output read by
RS-422/485
communication.
The reflected beam from
the beam emitting spot
is blocked.
Move the position of the beam
projection spot or change the
mounting direction of the
sensor head
so the reflected
beam should not be blocked.

The beam emitting spot
is applied to the R
portion (curved surface)
of the measurement
object.
Apply the beam projection spot
to the top of R portion or adjust
the beam diameter so it comes
larger by moving the
measurement object back and
forth within the measurement
range.


The reflected beam has
directionality because
the surface of the object
is hairline-finished.
Check the
mounting direction
of sensor head.


The received light
intensity is insufficient
because the sampling
cycle is too short.
Set a longer
sampling cycle
or
shutter time
(when shutter time
is set to a fixed value)

MEAS
LED
The alarm
indicator lights up
and measurement
cannot be done.
The measurement
range is limited.
The sampling cycle is
too long and this causes
excessive received light
intensity beyond the
adjustable range.
Set a shorter
sampling cycle
and reduce the emitted light
intensity
(enter a smaller
number to the shutter time).
