Series connection error, er-
ror in total number of beam
channels
The number of sensors in se-
ries connection exceeds the
specified limit.
Limit the number of sensors in series connection
to 5 or less.
The total number of beam
channels of the sensors in
series connection exceeds
the specified limit.
Limit the total number of beam channels to 256
or less.
Incorrect emitter and receiver
connection when connected
in a series connection.
Connect emitters to emitters and receivers to re-
ceivers using a series connection cable.
In a series connection, the
DIP switches 1 / 2 (synchro-
nization method) are not all
set to the same state.
Set all DIP switches 1 / 2 (synchronization meth-
od) to the same state.
End cap is not attached.
Make sure the end cap is installed correctly.
Cable for series connection is
disconnected.
• Make sure the cable for series connection is
connected correctly.
• Replace the cable for series connection.
Another error has generated. Check the operation of other sensors in series
connection.

Emitter and receiver system
mismatch.
The emitter system and re-
ceiver system do not match.
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)

Scattered light error.
Scattered light is received,
or light emitted from a differ-
ent model No. is received.
After turning on the power, make sure that the

Control output (OSSD 1 / 2)
error.
The control output 1 (OSSD
1) wire (black) or the con-
trol output 2 (OSSD 2) wire
(white) is shorted to 0V or +V.
Connect the control output 1 (OSSD 1) wire
(black) and the control output 2 (OSSD 2) wire
(white) to the safety relay unit, external device
(forcible guide relay or magnetic conductor),
safety controller, or safety PLC.
The current values of the control output 1 (OSSD
1) wire (black) and the control output 2 (OSSD 2)
wire (white) must be within the specified range.
The control output 1 (OSSD 1)
wire (black) and control output
2 (OSSD 2) wire (white) are
shorted to each other, or to
another input / output wire.
Excessive current is flowing
in the control output 1 (OSSD
1) wire (black) or control out-
put 2 (OSSD 2) wire (white).
