(5) Cutting buttons. Controls the knife via the hydraulic system. Pressing
both buttons within 0.5 second applies power to the control unit controlling the
operation of solenoids in the hydraulic system control block.
(6) Clamp foot pedal. Controls the operation of the clamp. When pressed,
trip dogs mounted on the pedal axle close the clamp pedal switch (S309) and press
in the clamp control valve in the hydraulic system control block. This initiates
sequences of operation (Table 5-16) in the electronics and hydraulics that control
the operation of the clamp when using the foot pedal.
(7) Backgauge control knob. Controls the movement of the backgauge, via a
control knob, limit switches, and a button. The control knob is mounted on one end
of a metal rod, with a toothed gear on the other end, and a trip dog cam mounted on
the middle of the rod. Two switches are mounted next to the trip dog cam. Pushing
the control rod in will control the contacts on one switch (S18), and pulling it out
will control the contacts of the other switch (S10). Pushing the control knob in
activates switch (S18) which disengages the backgauge brake. The toothed gear
engages a toothed gear on the table spindle. This allows turning of the knob to finely
adjust the position of the backgauge. Pulling the control knob out activates switch
(S10) which allows the backgauge motor to turn in a direction that allows the
backgauge to move forward. Pushing the button in the middle of the control knob
activates switch (S14). Activating this switch allows the backgauge motor to turn in
a direction that allows the backgauge to move back.
