The number of sensors in se-
ries connection exceeds the
specified limit.
The total number of beam
channels of the sensors in
series connection exceeds
the specified limit.
Incorrect emitter and receiver
connection when connected
in a series connection.
In a series connection, the
DIP switches 1 / 2 (synchro-
nization method) are not all
set to the same state.
End cap is not attached.
Cable for series connection is
disconnected.
Another error has generated.
The emitter system and re-
ceiver system do not match.
Scattered light is received,
or light emitted from a differ-
ent model No. is received.
Contact our office.
• Check the noise environment of the device.
• Check the connections, supply voltage, and
power supply capacity.
• Replace the device.
• Make sure that the receiver will not receive
scattered light at the time of power ON.
l i g h t • Light from a different model set to the same
frequency may be received. Change the setting
of the DIP switches 1/2 to a different frequency.
i s • Follow the instructions in "2-3-4-3 Preventing
Mutual Interference by Device Placement"
Limit the number of sensors in series connection
to 5 or less.
Limit the total number of beam channels to 256
or less.
Connect emitters to emitters and receivers to re-
ceivers using a series connection cable.
Set all DIP switches 1 / 2 (synchronization meth-
od) to the same state.
Make sure the end cap is installed correctly.
• Make sure the cable for series connection is
connected correctly.
• Replace the cable for series connection.
Check the operation of other sensors in series
connection.
Make sure the beam pitch, number of sensors
and number of beam channels of the emitter and
receiver match.
Wire the output polarity setting / lockout release
input wire (pale blue) of the emitter and the re-
ceiver in the same way.
• Using PNP output: Connect to 0V (blue)
• Using NPN output: Connect to + V (brown)
After turning on the power, make sure that the
receiver does not receive scattered light.
If light emitted from a different model No. is re-
ceived, follow the instructions in "2-3-4-3 Pre-
venting Mutual Interference by Device Place-
ment".
