[Digital error indicator: ]
Setting data error of this device
Series connection is in-correct.
Check that the cable for series connection does not short-circuit,
or is connected to the correct position (emitter for emitter, receiver
for receivers).
_ j
Check the noise status around this device.
Internal error

[Digital error indicator: ]
System error between emitter and receiver
Systems are different between emitter
and receiver.
Set the same value to the number of beam channels of emitter and
receiver and the output polarity setting wire (shield).
[Digital error indicator: ]
Series connection error
The serial signal short-circuits or comes
down.
< _ __=
Check that the cable for series connection does not short-circuit,
or is connected to the correct position (emitter for emitter, receiver
for receiver). Check the error contents of the device connected by
the cable for series connection.
Any of the main / sub sensor is in error.

Interlock setting error
Voltage level of interlock setting input
wire (pale purple) or emission halt input
/ reset input wire (pink) is unstable.
Wire the interlock setting input wire (pale purple) and emission halt
input / reset input wire (pink) correctly.

Muting lamp error
Muting lamp output wire (red) short-
circuits with 0V or +V.
Wire the muting lamp output wire (red) correctly.
<[ {_]j ]__
Muting lamp output short-circuits with
other I/O wires.
[]j{
muting lamp output.
Output polarity setting wire (shield) and
muting lamp output wire (red) are not
correctly wired.
Wire the output polarity setting wire (shield) correctly.
(0V: PNP output, +V: NPN output)
Wire the muting lamp output wire (red) to +V.
Output circuit error.
Output circuit is damaged. Replace this device.
[Digital error indicator: ]
Wiring error of the output polarity setting
wire (shield)
Output polarity setting wire (shield) comes
down or short-circuits with other I/O wires.
Output polarity setting wire (shield) con-
nection of emitter / receiver is incorrect.
Wire the output polarity setting wire (shield) correctly.
(0V: PNP output, +V: NPN output)
Wire the output polarity setting wire (shield) of the receiver correctly.
