Cause Remedy
[“ ” blinks]
Power supply voltage er-
ror
The voltage of the power sup-
plied to the device exceeds the
specified range.
Make sure the power supply voltage conforms to
the specification.
[“ ” lights]
Synchronization error
Mismatch between synchroniza-
tion method and wiring.
The wiring and synchronization method (line syn-
chronization, optical synchronization) must be
made to match. To change the synchronization
method, refer to
“3-9 DIP Switch Settings”
.
For wiring, refer to “2-5 Wiring” .
Line synchro-
nization
Synchronization
+ wire (orange) or
synchronization
- wire (orange /
black) is shorted
or broken.
Make sure that the synchroni wire (or-
ange) and synchronization - wire (orange / black)
are connected correctly.
The emitter has
generated an er-
ror.
Check the operation of the emitter.
Optical syn -
chronization
The beam axes
of the top and
bottom ends are
not received.
Make sure the beam axis of either the top end or
bottom end is received.
Significant noise
outside the speci-
fied range is be-
ing received.
Check the noise environment of the device.
Cable for series
connection has
failed.
Replace the cable for series connection.

Emitter error
Emitter is in lockout state. Check a digital indicator (yellow) of emitter.
[“ ” blinks]
Effects of noise or power
supply, or internal circuit
failure.
The device is affected by noise
or the power supply.
An internal circuit has failed.
Check the noise environment of the device.
Check the connections, supply voltage, and power
supply capacity, and check for scattered light.
If you are extending the synchroni wire
(orange) and synchronization - wire (orange /
black) using a cable other than the special-use
cable, use a 0.2mm
2
or more twisted pair cable.
If the problem persists, check the number that is
blinking in the digital indicator (yellow) and the
number of times it blinks, and contact our office.

Synchronization error
The other receiver connected in
series is locked out.
Check the digital indicator (yellow) of the other re-
ceiver connected in series.
<Interlock indicator lights yellow>
Cause Remedy
The control output (OSSD 1 / 2) has been turned OFF by
interlock.
Perform a reset [Open test / reset input wire (pink)
→ Short to 0V or +V → Open].
If the interlock function is not needed (When auto
reset is used), open the interlock setting input wire
(pale purple), and isolate.
