Troubleshooting of emitter
Symptom
Cause
Remedy
All indicators are off.
Power is not being supplied.
Check that the power supply capacity is sufficient.
Connect the power supply correctly.
Supply voltage is out of the
specified range.
Provide the supply voltage within the specified
range.
Connector is not connected
securely.
Connect the connector securely.
Fault indicator (yellow)
lights or blinks.
[Blinks once]
Number of total units / number
of total beam channels error
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.
[Blinks twice]
Auxiliary output error
Connect the auxiliary output wire correctly.
[Other than the above]
Effect from noise / power sup-
ply or failure of internal circuit
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
2
or
more shielded twisted pare cable.
Even if the error is not eliminated, contact Pana-
sonic Industrial Devices SUNX.
Emission halt indicator
(orange) lights up.
Emission is in halt condition.
Connect the test input (emission halt input) wire
correctly. The logic varies depending on the cable
to be used.
The synchronization wire error Connect the synchronization wire correctly.
The receiver does not work.
Check the operation of the receiver side.
The interference prevention
wire error (Beam synchroniza-
tion using 4-core cable: slave
setting)
Connect the interference prevention wire correctly.
Master / slave setting error
(Beam synchronization using
4-core cable: master setting)
Set the master / slave setting to “master”.
The master sensor does not
work.
Check the master side sensor.
Operation indicator re-
mains lit in red (light is
not received).
The beam channels of the
emitter and the receiver are
not correctly aligned.
Align the beam channels.
About counting blinks of the error indicator, count blinks from 2 seconds of no blinking.
