Synchronization error
<Upper application indicator and lower application indicator light blue, and OSSD indicator lights red>
Beam received with fixed blanking function valid
When the floating blanking function is valid, the blocked
beam is lower than the lowest beam.
<Interlock indicator lights yellow>
The control output (OSSD 1 / 2) has been turned OFF by in-
terlock.
<Upper application indicator and lower application indicator light red or are OFF>
Beam axes not aligned.
Synchronization + wire (orange) or synchronization - wire
(orange / black) error.
Synchronization + wire (orange) or synchronization - wire
(orange / black) has shorted or is broken.
Take action as indicated in the troubleshooting for the emitter and receiver. If the problem per-
sists, contact our office.

wires are connect-

Emitter is in lockout state.
The device is affected by noise
or the power supply.
An internal circuit has failed.

Cause
Make sure that the synchronization + wire (or-
ange) and synchronization - wire (orange / black)
are connected correctly.
Check the operation of the emitter.
Make sure the beam axis of either the top end or
bottom end is received.
For optical synchronization, use 5-core cables.
Check a digital indicator (yellow) of emitter.
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 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 blink-
ing in the digital indicator (yellow) and contact our office.
Check the digital indicator (yellow) of the other re-
ceiver connected in series.
Check installation conditions and turn the power
OFF then ON.
Perform a reset [Open test / reset input wire (pink)
→ Short to 0V or +V → Open].
If the interlock function is not needed, open the in-
terlock setting input wire (pale purple), and isolate.
Perform beam axis adjustment.
Refer to "2-6 Adjustment".
Align the upper and lower directions between the
emitter and receiver.
Correctly connect the synchronization + wire (or-
ange) and synchronization - wire (orange / black).
