External device error
[Digital error indicator: ]
Effect from noise / power
supply or failure of internal
circuit
<Digital error indicator " " lights up>
Synchronization + wire (orange) or synchronization - wire
(orange / black) error.
Synchronization + wire (orange) or synchronization - wire
(orange / black) comes down or short-circuits.
Emitter error
<All beam-axis adjustment indicators (red) light up>
The beam channel with its fixed blanking function set into
valid receives light.
<OSSD indicator remains lit in red (light is not received)>
The beam channels are not correctly aligned.
If the device does not work normally after checking the items above, please consult Panasonic
Industrial Devices SUNX.
<Reference>
About counting blinks of the error indicator, count blinks from 2 seconds of no blinking.

Cause
Cause
Cause
Remedy
Replace the relay.
Replace the relay with proper response time.
Setting by the handy controller (SFB-HC) (op-
tional) is also possible.
Refer to "3-6 External Device Monitor Func-
tion."
Wire correctly to the relay.
Connect the auxiliary output wire (yellow-green /
black) and the external device monitor input wire
(yellow-green).
Set the external device monitor function to "in-
valid" using the handy controller (SFB-HC) (op-
tional).
Check if the auxiliary output wire (yellow-green /
black) is disconnected or short-circuited.
Reset to factory default (mode 0) by the handy
controller (SFB-HC) (optional).
Check the connecting locations of the bottom cap
cables.
Check the noise status around this device.
Check the wiring status, supply voltage, and
power supply capacity.
When the synchronization + wire (orange) and
synchronization - wire (orange / black) is extend-
ed with a cable other than exclusive cable, use a
2
0.2mm or more shielded twisted pair cable.
If this device still does not work, confirm number
of blinks of the error indicator and call to our local
office.
Remedy
Connect synchronization + wire (orange) or syn-
chronization - wire (orange / black) properly.
Refer to "2-5 Wiring."
Check the operation of the emitter side.
Remedy
Turn ON the power supply after checking the in-
stallation status.
Remedy
Align the beam channels.
Refer to "2-6 Adjustment."
Align the top / bottom direction of the beam chan-
nel between emitter and receiver.
