Cause
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.
Output circuit error.
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.

specified range.
Remedy
<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 damage. Replace the device.
<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).
Replace the safety relay.
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)".
Correctly connect the safety relay.
Refer to "2-5-7 Wiring Configuration for
Valid External Device Monitor Function
(Example of Control Category 4 Wiring)".
• 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".
• 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).
Make sure the power supply voltage conforms to
the specification.
