Measurement
error
The logical beam is not
emitted from the Sensor
Head.
The connection between the
S
ensor Head and the Sensor
Controller or the connection with
the extension fiber cable is not
normal.
Check the fiber cable connections. p.58
The fiber cable is disconnected. The Sensor Head needs to be
repa
ired.
Please contact an OMRON branch or
sales of
fice.
For Sensor Head repair, return as a
se
t with
the Calibration ROM.
p.58
The logical beam does
not com
e out of the
Sensor Controller.
The LIGHT OFF input line is short-
cir
cuited.
Check the wiring. p.69
The measured values
fluctuat
e gradually.
The operating ambient temperature
of Sensor Head or Controller is
fluctuating.
• Maintain a certain operating ambi-
ent temperature.
• Execute zero reset periodically
using the standard
object.

The warm-up time is inadequate. Wait 30 minutes after switching ON
the po
wer before using.
p.9
The measured values
differ f
rom the intended
values.
The scaling has not been done
cor
rectly.
Check the scaling setting. p.130
p.221
The zero reset value is not correct. Set the zero reset correctly. p.152
p.230
The serial numbers of the Sensor
He
ad and calibr
ation ROM do not
match.
Confirm the serial numbers match.
Input error No input signal received. Cables are not connected correctly. Check the input circuit and the wiring
for prop
er connection.
p.69
The signal line is disconnected.
Output error The judgment result
cannot be output
to an
external device.
Cables are not connected correctly. Check the output circuit and the
wiring for proper connection.
p.69
The signal line is disconnected.
The signal logic is not correct. Check the logic of the signal.
−
The RESET input line is short-
circuited.
Check the input circuit and the wiring
for proper connection.
p.69
The non-measurement setting is
set t
o “CLAMP”, and measurement
cannot be performed.
Set the non-measurement setting
c
orrectly. By selecting the non-
measurement setting to “KEEP”, the
judgment result before measurement
is disabled can be output.

The analog output is not
correct.
Cables are not connected correctly. Check the output circuit and the
wir
ing for proper connection.
p.72
The signal line is disconnected.
The voltage and current values are
off th
e meter.
Set the correct monitor focus based
on the measured value.
*2
An oscilloscope or a high-speed A/
D board is be
ing used.
Use of these devices may reduce the
resolution. Change the monitor focus
to minimize the effect.
