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.
The relay contact

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 relay.
Replace with a relay with a suitable response
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 relay.
Connect the auxiliary output wire (red) and exter-
nal device monitor input wire (pale purple).
Using the communication module SF4D-TM1 (op-
tion) 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 de-
fault setting (mode 0).
Make sure the power supply voltage conforms to
the specification.
