Operating Modes
System operating modes determine the start-up and operating behavior of a
F3S-TGR-CL system. Operating modes definitions rely on the operating
states presented above. Operating mode selection may be performed via the
configuration switches on the F3S-TGR-CL transmitter and receiver.
Note
If internal errors are detected by the system during power-up or operation, it
will enter the Error state with its safety outputs in the OFF state.
3-2-1
Automatic start
The F3S-TGR-CL will power-up with its safety outputs OFF, and if the detec-
tion zone is not obstructed, enters the MACHINE RUN state. In this state,
when an object is sensed entering the detection zone, the F3S-TGR-CL sys-
tem will change from MACHINE RUN to MACHINE STOP and remain in this
state until the obstruction is removed. Once the detection zone is clear, the
F3S-TGR-CL system will automatically change from MACHINE STOP to
MACHINE RUN.
3-2-2
Start/Restart Interlock
!WARNING
The TEST/RESTART button must be located so that the operator can see the
protected area when restarting, testing or overriding.
The F3S-TGR-CL will power-up with its safety outputs off and enter the
INTERLOCK state if the detection zone is clear. To initially enter the
MACHINE RUN state the operator must press and release the Restart button.
Once in the MACHINE RUN state, when an object is sensed entering the
detection zone, the system will change to the MACHINE STOP state. When
the detection zone is cleared, the system will not automatically change to
MACHINE RUN but enter the INTERLOCK state instead. The operator must
always press and release the Restart button to enter MACHINE RUN. If the
detection zone is not clear the Restart button will have no effect.
3-2-3
Pre-reset operation
The Pre-Reset function is used in installations where operators inside the
dangerous zone can be hidden by parts of the installation. A second Reset
pushbutton (Pre-reset) is added inside the dangerous zone. Before leaving
the dangerous zone, the operator has to operate the Pre-reset pushbutton.
This enables the Restart pushbutton outside the dangerous zone.
The F3S-TGR-CL will power-up with its safety outputs off and enter the
INTERLOCK state if the detection zone is clear. To initially enter the
MACHINE RUN state the operator must press and release the Pre-reset and
Restart button. Once in the MACHINE RUN state, when an object is sensed
entering the detection zone, the system will change to the MACHINE STOP
state. When the detection zone is cleared, the system will not automatically
change to MACHINE RUN but enter the INTERLOCK state instead. The oper-
ator must always press and release the Pre-reset and the Restart button in
this sequence to enter MACHINE RUN. If the detection zone is not clear the
Pre-reset or Restart button will have no effect.
