Safety-related Functions
Interlock Function
The F3SJ turns the safety outputs OFF when the power is turned ON
or when a beam is interrupted, and maintains this state until a reset
signal is applied. This state is called "interlock".
You can reset this interlock by 2 methods; “auto reset that
automatically turns safety output ON when an interrupting object is
removed” and “manual reset mode that keeps safety output OFF until
a reset signal is provided if the interrupting object is removed”.
Auto Reset Mode
When an interrupting object is removed, safety output automatically
turns ON. Auto reset is used on machines where a worker is not able
to enter the area between the detection zone and the hazardous part
of the machine.
Note: Auto reset is always used in the F3SJ-A@-TS series.
Auto reset wiring procedure:
Manual Reset Mode
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.
A sensor enters interlock state when:

Reset Input
Control output
1. Open the interlock selection
2. Short-circuit the reset input
3. Turn ON the power of F3SJ.
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 interrupted (restart interlock). After F3SJ is interrupted and
the machine stops, the machine can be restarted after safety is
ensured.

Interlock Function in a Muting System
Because the interlock selection input line is used as muting input 1
when using the muting function, the default setting is auto reset. Use
a setting tool for manual reset.
