( o r a n g e ) o r
synchronization
- wire (orange /
Line synchro-
black) is short-
nization
ed or broken.
The receiver

ated an error.
Synchroniza-
tion wires are
Optical syn-
connected us-
chronization
ing 8-core or
12-core cables.
The other emitter connected
in series is locked out.
The device is affected by
noise or the power supply.
An internal circuit has failed.
Receiver is in lockout state.
Cause
Digital indicator (yellow) is
blinking.
Auto reset was selected with
the test / reset input wire
(pink) open.
Manual reset was selected
with the test / reset input wire
(pink) connected to 0V or +V.
Make sure that the synchronization + wire (or-
ange) and synchronization - wire (orange / black)
are connected correctly.
Check the operation of the receiver.
For optical synchronization, use 5-core cables.
Check the digital indicator (yellow) of the other
emitter connected in series.
Check the noise environment of the device.
Check the connections, supply voltage, and pow-
er supply capacity.
If you are extending the synchronization + wire
(orange) and synchronization - wire (orange /
black) using a cable other than the special-use
cable, use a 0.2mm
If the problem persists, check the number that is
blinking in the digital indicator (yellow) and con-
tact our office.
Check an digital indicator (yellow) of receiver.
Check the number shown in the digital indicator.
<Using PNP output>
Connect the test / reset input wire (pink) to + V
(brown).
<Using NPN output>
Connect the test / reset input wire (pink) to 0V
(blue).
Open the test / reset input wire (pink).
