Control output (OSSD 1 /
2) error.
The output polarity setting /
lockout release input wire (pale
blue), and the control output
1 (OSSD 1) wire (black) and
control output 2 (OSSD 2) wire
(white) are not connected cor-
rectly.
<Using PNP output>
• Connect the output polarity setting / lockout re-
lease input wire (pale blue) to 0V (blue).
• 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.
<Using NPN output>
• Connect the output polarity setting / lockout re-
lease input wire (pale blue) to + V (brown).
• 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.
Output circuit error. Output circuit damage. Replace the device.

Error in wiring of output
polarity setting / lockout
release input wire (pale
blue).
Output polarity setting / lockout
release input wire (pale blue)
is broken or shorted to another
input / output wire.
Incorrect connection of output
polarity setting / lockout release
input wire (pale blue) of receiver
side of emitter / receiver.
<Using PNP output>
Connect the output polarity setting / lockout re-
lease input wire (pale blue) to 0V (blue).
<Using NPN output>
Connect the output polarity setting / lockout re-
lease input wire (pale blue) to + V (brown).

External device error.
When a safety
relay is used
The safety re-
lay contact has
welded.
Replace the safety relay.
T h e r e s p o n s e
time of the safety
relay is slow.
Replace with a safety relay with a suitable re-
sponse time.
This can also be set using the communication
module SF4D-TM1 (option) and Configurator Light
Curtain software.
Refer to “3-6 External Device Monitor Function
(8-core cable, 12-core cable)” .
S a f e t y r e l a y
contact "b" is not
connected.
Correctly connect the safety relay.
Refer to
“2-5-7 Wiring Configuration for
Valid External Device Monitor Function
(Example of Control Category 4 Wiring)”
.
When the ex-
ternal device
monitor func-
tion is invalid.
The auxiliary out-
put wire (red) and
external device
monitor input wire
(pale purple) are
not connected.
• Connect the auxiliary output wire (red) and ex-
ternal device monitor input wire (pale purple).
• Using the communication module SF4D-TM1
(option) and Configurator Light Curtain software,
set the external device monitor function to "Not
used".
Auxiliary output
does not operate
correctly.
• Check if the auxiliary output wire (red) is broken
or has shorted.
• Using the communication module
SF4D-TM1
(option) and Configurator Light Curtain software,
return the auxiliary output setting to the factory
default setting (mode 0).

Power supply voltage error
The voltage of the power sup-
plied to the device exceeds the
specified range.
Make sure the power supply voltage conforms to
the specification.
