Cause
Power is not being supplied.
Supply voltage is out of the
specified range.
Connector is not connected
securely.
[Digital error indicator: ]
Number of total units / number
of total beam channels error
[Digital error indicator: ]
Control output (OSSD 1 / 2)
error
[Digital error indicator: ]
Extraneous light error
[Digital error indicator: ]
External device monitor error
[Other than the above]
Effect from noise / power sup-
ply or failure of internal circuit
The beam channels of the
emitter and the receiver are
not correctly aligned.
The beam channels of the
emitter and the receiver are
not correctly aligned.
Number of total units / number
of total beam channels error
The master and slave settings
are different. (Beam synchro-
nization using 4-core cable)
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 same value to the numbers of emitter and
receiver.
Connect the control output (OSSD 1 / 2) wire cor-
rectly.
Check the type of the bottom connector.
Cable of the receiver: Grey (with black stripe)
Prevent any extraneous light from entering the re-
ceiver.
Connect the external device monitor input wire cor-
rectly.
Replace the relay unit.
Replace the relay unit having appropriate response
time.
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.
Align the beam channels.
Align the beam channels.
Set the same value to the numbers of emitter and
receiver.
Set the setting identically.
