11. Troubleshooting

● Troubleshooting of emitter
Symptom
All indicators are off.
Fault indicator (yellow)
lights or blinks.
Emission halt indicator
(orange) lights up.
Operation indicator re-
mains lit in red (light is
not received).
<Reference>
About counting blinks of the error indicator, count blinks from 2 seconds of no blinking.

Cause
Power is not being supplied.
Supply voltage is out of the
specified range.
Connector is not connected
securely.
[Blinks once]
Number of total units / number
of total beam channels error
[Blinks twice]
Auxiliary output error
[Other than the above]
Effect from noise / power sup-
ply or failure of internal circuit
Emission is in halt condition.
The synchronization wire error Connect the synchronization wire correctly.
The receiver does not work.
The interference prevention
wire error (Beam synchroniza-
tion using 4-core cable: slave
setting)
Master / slave setting error
(Beam synchronization using
4-core cable: master setting)
The master sensor does not
work.
The beam channels of the
emitter and the receiver are
not correctly aligned.

Remedy
Check that the power supply capacity is sufficient.
Connect the power supply correctly.
Provide the supply voltage within the specified
range.
Connect the connector securely.
Connect the end cap properly. Connect the cable
for series connection correctly.
Check the model (emitter / receiver) of sub sensor
exclusive for series connection.
Set the number of the sensors in series connec-
tion, and a number of total beam channels within
the specification.
Connect the auxiliary output wire correctly.
Check the noise status around this device.
Check the wiring, supplied voltage and power sup-
ply capacity.
When the synchronization cable is extended with a
cable other than exclusive cable, use a 0.2mm
more shielded twisted pare cable.
Even if the error is not eliminated, contact Pana-
sonic Industrial Devices SUNX.
Connect the test input (emission halt input) wire
correctly. The logic varies depending on the cable
to be used.
Check the operation of the receiver side.
Connect the interference prevention wire correctly.
Set the master / slave setting to "master".
Check the master side sensor.
Align the beam channels.
