FRONT VISE - This switch has three positions, CLOSE, OPEN, and HOLD. In CLOSE, the
vise will close all the way, or until it encounters enough resistance to stop it. With the switch
held in the OPEN position the vise will open all the way or until the switch is released. With the
switch in the HOLD position, the vise will stay where it is and will not move freely although it
will not resist a large force indefinitely without creeping.
HEAD CONTROL - This switch has three positions: UP, HOLD and DOWN. The switch is
inactive unless the PLC is in manual mode. In the UP position, the head will rise until the
switch is released. In the HOLD position the head will stay still. In the DOWN position the head
will descend until it reaches the Head Down Limit Switch. The speed of descent is controlled
by the Head Feed and Head Force Limit controls.
NOTE: On canted head machines, the head rises up by a distance measured from latest
established down position. Therefore changing position of the down limit switch will also
change the head’s relative up position. It is strongly recommended that the head down
position be re-established every time the movable guide arm is repositioned and head
down limit switch position changed.
BLADE START - The blade can be started only when the hydraulics are running in either
manual or auto mode.
NOTE: In automatic Mode the head will not descend until the blade has been started, which
the PLC will prompt the operator to do so.
HYDRAULIC START - To start the hydraulic system, the switches for the head and both
vises must be in the "NEUTRAL" position. The "HYDRAULIC START" button must be
depressed and held in momentarily until the PLC display becomes active.
CYCLE START / PAUSE - This button starts the cutting cycles and will stay illuminated
white until the cycles are completed. The PLC control system will prompt you to start the blade
if it is not running. The machine will then begin the automatic cycle until completed when it will
shut itself off. The current cycle can be PAUSED by pressing this button at any time during a
cycle and restarted by pressing it again.
COOLANT - This switch has three positions, WASH, OFF, and ON. In the WASH position,
the coolant system will operate when there is power to the machine, this allows using the wash
gun to clean the machine. In the OFF position, the coolant system is inactive. In the ON
position, the coolant system will run only when the head is descending. This minimizes coolant
carry over on the stock.
SHUTTLE VISE - This switch has three positions, CLOSE, OPEN, and HOLD. In CLOSE,
the vise will close all the way, or until it encounters enough resistance to stop it. With the
switch held in the OPEN position the vise will open all the way or until the switch is released.
With the switch in the HOLD position, the vise will stay where it is and will not move freely
although it will not resist a large force indefinitely without creeping.
