sensed entering the detection zone the F3SL system will change from machine run to interlock. The F3SL sys-

machine run state, the operator must press and release the start button. If any obstruction is present in the de-
tection zone when the start button is pressed and released, the F3SL system will remain in the interlock state.
Note:
The definitions above mention a start button. See Section 10–“Connecting To The Machine Control Cir-
cuit” for wiring of the start button.
4-3 Operating Mode Selection

these switches before mounting the recieiver.
WARNING
Perimeter guarding installations must not allow a machine or robot to restart automatically. Use a start switch
placed outside and within view of the hazardous area.
