Interlock Function
The F3SJ turns the safety outputs OFF when its power is turned on or its beam is interrupted and holds
this state until reset input is applied. This state is called "interlock".
Two methods can be used to reset the interlock state: "auto reset that automatically turns control
outputs ON when the interrupting object is removed" and "manual reset mode that keeps control
outputs OFF until a reset signal is provided, if the interrupting object is removed".
Auto Reset
When the interrupting object is removed from the detection zone, the safety outputs automatically turn
ON. Auto reset is used on machines where a worker is not able to enter the zone between the
detection zone and the hazardous part of the machine.
To wire auto reset:
1.
Open the interlock selection input line, or short-circuit it to 9 to 24V (pin 1/white).
2.
Short-circuit the reset input line to 0 to 1.5V (pin 4/yellow).
3.
Turn ON the power to the F3SJ.
