5-1 Troubleshooting of Emitter

Symptom
All indicators are off.
Fault indicator (yellow) lights
or blinks.
Emission halt indicator (or-
ange) lights up.
Operation indicator remains lit in
red (light is not received). (Note)
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.

Cause
Power is not being supplied.
Supply voltage is out of the
specified range.
Connector is not connected securely. Connect the connector 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 synchronization us-
ing 4-core cable: slave setting)
Master / slave setting error
(Beam synchronization using
4-core cable: master setting)
The master sensor does not work. Check the master side sensor.
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 end cap properly. Connect the cable
for series connection correctly.
Check the model (emitter / receiver) of sub sen-
sor exclusive for series connection.
Set the number of the sensors in series connection, 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 supply capacity.
When the synchronization cable is extended with
a cable other than exclusive cable, use a 0.2mm
or 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 correct-
ly. The logic varies depending on the cable to be used.
Check the operation of the receiver side.
Connect the interference prevention wire cor-
rectly.
Set the master / slave setting to "master".
Align the beam channels.
