[Digital error indicator: ]
Output polarity setting wire
(shield) 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.
Receiver error
<Emission halt indicator (orange) lights up>
Emission is in halt condition
(Device error or interlock set-
ting error)
<All beam-axis adjustment indicators (red) light up>
The beam channel with its fixed blanking function set into
valid receives light.
<Operation indicator remains lit in red (light is not received) (Note)>
The beam channels are not correctly aligned.
Sensing range is shortened because of the emission amount
control function.
Note: Since the color of the operation indicator changes according to ON / OFF status of the control output (OSSD
1 / 2), the operation indicator is marked as "OSSD" on the device.
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
Output polarity setting wire
(shield) comes down or short-
circuits with other I/O wires.
Output polarity setting wire
(shield) connection of emitter
/ receiver is incorrect.
Affected by noise / power
supply.
Internal circuit is broken
down.
Cause
Cause
Error indicator (yellow) lights
or blinks.
Emission halt input / reset in-
put wire (pink) is open when
selecting auto-reset.
Emission halt input / reset
input wire (pink) is connected
to 0V or +V when selecting
manual reset.
Cause
Cause
Remedy
Wire the output polarity setting wire (shield) cor-
rectly. (0V: PNP output, +V: NPN output)
Wire the output polarity setting wire (shield) of
the receiver correctly.
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 receiver side.
Remedy
Check the contents of the digital error indicator.
Wire the emission halt input / reset input (pink)
wire to 0V or +V.
Refer to "2-5 Wiring."
Open the emission halt input / reset input (pink)
wire. Refer to "2-5 Wiring."
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.
Reset to factory default (CLR) by the handy con-
troller (SFB-HC) (optional).
