FRONT VISE
This switch has three positions, OPEN, HOLD and CLOSE. 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 indenitely without creeping. In CLOSE, the vise will
close all the way, or until it encounters enough resistance to stop it.
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 it trips the head up limit,
which is adjustable. In the HOLD position the head will stay still. In the DOWN position the
head will descend until it reaches the bottom of the stroke. The speed of descent is
controlled by the Head Feed and Head Force Limit controls.
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.
