Cause
Remedy
[Digital error indicator: ]
Output polarity setting wire
(shield) error
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.
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.
[Digital error indicator: ]
Effect from noise / power
supply or failure of internal
circuit
Affected by noise / power
supply.
Internal circuit is broken
down.
Check the noise status around this device.
Check the wiring status, supply voltage, and
power supply capacity.
When the synchroni wire (orange) and
synchronization - wire (orange / black) is extend-
ed with a cable other than exclusive cable, use a
0.2mm
2
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.
<Digital error indicator “ ” lights up>
Cause
Remedy
Synchroni wire (orange) or synchronization - wire
(orange / black) error.
Synchroni wire (orange) or synchronization - wire
(orange / black) comes down or short-circuits.
Connect synchroni wire (orange) or syn-
chroni wire (orange / black) properly.
Refer to “
2-5 Wiring
.”
Receiver error
Check the operation of the receiver side.
<Emission halt indicator (orange) lights up>
Cause
Remedy
Emission is in halt condition
(Device error or interlock set-
ting error)
Error indicator (yellow) lights
or blinks.
Check the contents of the digital error indicator.
Emission halt input / reset in-
put wire (pink) is open when
selecting auto-reset.
Wire the emission halt input / reset input (pink)
wire to 0V or +V.
Refer to “
2-5 Wiring
.”
Emission halt input / reset
input wire (pink) is connected
to 0V or +V when selecting
manual reset.
Open the emission halt input / reset input (pink)
wire. Refer to “
2-5 Wiring
.”
<All beam-axis adjustment indicators (red) light up>
Cause
Remedy
The beam channel with its fixed blanking function set into
valid receives light.
Turn ON the power supply after checking the in-
stallation status.
<Operation indicator remains lit in red (light is not received) (Note)>
Cause
Remedy
The beam channels are not correctly aligned.
Align the beam channels.
Refer to “
2-6 Adjustment
.”
Align the top / bottom direction of the beam chan-
nel between emitter and receiver.
Sensing range is shortened because of the emission amount
control function.
Reset to factory default (CLR) by the handy con-
troller (
SFB-HC
) (optional).
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.
About counting blinks of the error indicator, count blinks from 2 seconds of no blinking.
