When the judgment value (P.V.) is "
" the judgment output becomes all OFF (When
Normal Open is set), and the analog output is fixed to the output lower limit.
"10. Analog output scaling" (page 4-32)
In cases other than the above, the judgment output and analog output keeps the output status
immediately before the output.
Standard waveform
registration error 2
The light-receiving amount is
too large to register the stan-
dard waveform (Gain adjust-
ment).
(The error is displayed for
approx. 3 seconds and the
normal screen is restored.)
Check whether the external scattering light
enters the laser receiver part or not. Then regis-
ter the standard waveform (Gain adjustment)
again.
"3-4 Registering the Standard Waveform
(Gain adjustment)" (page 3-9)
Standard waveform
registration error 3
The standard waveform can-
not be registered (Gain
adjustment) because the
receiver is receiving the laser
light of the transmitter con-
nected to another amplifier
added.
(The error is displayed for
approx. 3 seconds and the
normal screen is restored.)
Use the transmitter and receiver in combination
of the same amplifier connected.
Standard waveform
registration error 4
The light-receiving waveform
is abnormal and the standard
waveform cannot be regis-
tered (Gain adjustment).
(The error is displayed for
approx. 3 seconds and the
normal screen is restored.)
Register the Standard Waveform (Gain adjust-
ment) again after realigning the optical axis.

Reference
If the internal measurement value (R.V.) becomes [-----] because the target is
out of the measurement range, the internal measurement value (R.V.) retains
the value immediate before the target disappears for the period the response
time elapses. After the response time elapses, the internal measurement value
(R.V.) becomes [-----].

Description
Corrective actions
The internal mea-
surement value
(R.V.) is displayed
as "
".
A target is not in the measure-
ment range.
A target cannot be measured.
Adjust the target to correctly fall within the mea-
surement range.
The laser emission stop input
is ON.
Set the laser emission stop input to OFF.
Check the wiring of the laser emission stop
input.
