Exiting Tool Setup Mode
Tool Setup mode can be exited by pressing any of the Defender panel buttons when the tools
are open. This will return the Defender panel to the previous operating mode. If the tools are
not open, the Status window will display the message
Open tools to enable button function
.
If the machine is idle for more than five minutes the Setup mode will be cancelled. If the
machine does not have open tools when the timeout occurs, the Defender will wait until the
tools are opened. It will then exit Tool Setup mode, and return to the previous operating mode.
6.11
Emergency Stop Operation
Depending upon your installation, external inputs may be connected to the PGS-2 which
trigger emergency stops (E-Stops). When an E-Stop occurs, operation of the machine is
immediately stopped, and cannot continue until all E-Stop conditions are cleared.
•
Emergency Stop Button.
This allows the Operator to manually trigger an E-Stop of
the machine. Normal operation cannot be continued until the E-Stop switch is reset.
•
Rear Gate.
A safety switch is connected to the rear gate of the press brake, and
triggers an E-Stop when the rear gate is opened. The E-Stop cannot be cleared until
the rear gate is closed.
•
Side Gates.
Safety switches connected to the side gates of the press brake trigger
an E-Stop when either gate is opened during normal operation.
The behaviour of the system when the side gates are open depends upon which E-Stop
option has been selected during installation.
E-Stop Option 1.
If any side gate is open no down movement is allowed. The E-Stop cannot
be cleared until the door is closed.
E-Stop Option 2.
If one side gate is open (and all E-Stops have been cleared) the machine
may be operated, but down movement is restricted to crawl speed. The message
CRAWL
SPEED side gate open
–
CLOSE SIDE GATE
is displayed. If both side gates are open no down
movement is allowed.
In all of the cases listed above, the User Interface Panel will display the reason for the E-
Stop, and the Operator action required.
6.12
External Device Monitor (EDM)
Depending upon your installation, External Device Monitors (EDM) may have been
connected to the PGS-2 which monitor the operation of valves, relays or solenoids. The
Defender continually monitors these devices to ensure that they are operating correctly.
