System Configuration and Functions
 Manual Reset
When a reset input is given while no interrupting object exists in a detection zone, the safety outputs
turn ON. This allows the machine to be manually reset using a reset switch after ensuring safety,
preventing unexpected startup (EN1037).
A sensor enters interlock state when:
•The power is turned ON (start interlock). This is useful if you want to keep the machine stopped until
start inspection is completed after the power is turned ON.
•F3SJ is blocked (restart interlock). After the F3SJ is blocked and the machine stops, the machine can
be restarted after safety is ensured.
Manual reset wiring procedure:
1. Connect the interlock selection input line to 0 to 1.5V. (pin 1/ white)
2. Connect the reset input line to 0 to 1.5V via a reset switch (N.O. contact). (pin 4/ yellow)
3. Keep the reset switch contact open, and turn ON the power to the F3SJ.
Wiring for manual reset mode p.27
To reset:
1. Cycle the reset switch to apply a voltage of 0 to 1.5V for 250ms or longer to the reset input, and then
open the switch to apply a 9 to 24V signal or open circuit.
A reset switch must be installed outside of the hazardous zone in a location that provides a clear view of the hazardous
zone.
 Setting Change by the Setting Tool
