System error between emitter
and receiver
Systems are different be-
tween emitter and receiver.
Set the same value to the numbers of emitter and
receiver and that of beam channel, and the shield
wires.

Extraneous light error
Extraneous light is entering
or light from other model is
entering.
When the power is ON, prevent any extraneous
light from entering the receiver.
If the extraneous light is coming from this device,

Control output (OSSD 1 / 2)
error
Control output 1 (OSSD 1)
wire (black) and control out-
put 2 (OSSD 2) wire (white)
short-circuits with 0V or +V.
Wire the control output 1 (OSSD 1) wire (black)
or control output 2 (OSSD 2) wire (white) cor-
rectly.
Refer to “
2-5 Wiring
.”
Current value should be within the specified
control output 1 (OSSD 1) wire (black) or control
output 2 (OSSD 2) wire (white).
Refer to “
6-1 Specifications
.”
Control output 1 (OSSD 1)
wire (black) or control out-
put 2 (OSSD 2) wire (white)
shortcircuit respectively, or
shortcircuits with other I/O
wires.
Excessive incoming current
flows in the Control output 1
(OSSD 1) wire (black) and

wire (white).
Output polarity setting wire
(shield) and control output 1
(OSSD 1) wire (black) and
control output 2 (OSSD 2)
wire (white) are not correctly
wired.
Wire the output polarity setting wire (shield) cor-
rectly.
(0V: PNP output, +V: NPN output).
Wire the control output 1 (OSSD 1) wire (black)
or control output 2 (OSSD 2) wire (white) cor-
rectly.

Output polarity setting wire
(shield) error
Output polarity setting wire
(shield) comes down or short-
circuits with other I/O wires.
Output polarity setting wire
(shield) connection of emitter
/ receiver is incorrect.
Wire the output polarity setting wire (shield) cor-
rectly. (0V: PNP output, +V: NPN output).
Wire the output polarity setting wire (shield) of the
receiver correctly.
