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 sen-
sor exclusive for series connection.
Set the same value to the numbers of emitter and
receiver.
Connect the control output (OSSD 1 / 2) wire correctly.
Check the type of the bottom connector.
Cable of the receiver: Grey (with black stripe)
Prevent any extraneous light from entering the
receiver.
Connect the external device monitor input wire
correctly.
Replace the relay unit.
Replace the relay unit having appropriate re-
sponse time.
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.
Align the beam channels.
Align the beam channels.
Set the same value to the numbers of emitter and
receiver.
Set the setting identically.
