Figure 3-7: Rear Control Panel
1. PULL ROLL PRESSURE DISPLAY - Displays
the air pressure pushing the upper pull roll down.
2. MAIN ROLL UP/DOWN - Sets the upper main
roll to the up (load) or down (operate) position.
3. PULL ROLL PRESSURE CONTROL - Varies
the air pressure fed to the cylinders that drive the
upper pull roll down.
4. GBC LOGO AUTOMATIC/MANUAL MODE
CONTROL -Toggles between Automatic Tension
and Manual Tension mode. In Automatic Tension
mode, the system automatically adjusts the brake/
clutch pressure. In Manual Tension mode the sys-
tem doesn’t automatically adjust these pressures
(indicated by an H or L in the accumulator dis-
play). In the Automatic Tension mode with the
motor stopped, setting a web force (tension) for
either a clutch or brake loads that force into the
internal computer, which then automatically
adjusts the air pressure sent to the clutch/brake to
obtain the required web tension based on the roll
size. When you enter the setting and then turn the
motor on, the indicator changes from reading the
web force to the actual pressure sent to the brake to
attain the required web force calculated for that roll
size. In Manual Tension mode the display reads
actual pressure sent to the clutch/brake. This pres-
sure stays set until you change it. The computer
will not override your setting or change the display.
5. SPEED/ACCUMULATOR DISPLAY - Dis-
plays either the accumulator or speed, depending
on which you have selected with the SPEED/
ACCUMULATOR TOGGLE. A letter in the dis-
play before the speed readout indicates the mode of
operation:
H - Manual mode with the preheater off.
P - Automatic mode with the preheater on.
L - Manual mode with the preheater on.
No letter - Automatic mode with the preheater off.
The following codes alert you to machine status:
.0 - The machine is reset and ready to be started.
8888 - Main power has just been turned on and the
main reset has not yet been pressed.
In addition to these codes, if an emergency stop
button or kick cable is activated, the decimal point
will no longer be displayed (for example, 3.0 would
change to 3 0). Simply resetting the emergency stop
button or kick cable does not change the display.
You must also press the main machine reset button
for display to read .0 indicating the machine is
ready to be started. Note that you must reset the
emergency stop button or kick cable before press-
ing the main machine reset or the machine will not
be reset.
6. SPEED ADJUSTMENT - Adjusts the speed of
the machine from zero to maximum as the control
is turned clockwise. Turn control knob slowly for
best results.
7. PULL ROLL TORQUE ON/OFF - Allows you
to turn the pull roll clutch (torque) pressure on or
off without changing the pressure settings.
8. PULL ROLL PULL FORCE DISPLAY - Dis-
plays the air pressure of the clutch (torque or pull
force).
9. PULL ROLL UP/DOWN - Sets the pull roll to
the up (load) or down (operate) position.
10. PULL ROLL TORQUE CONTROL - Varies the
air pressure fed to the clutch that drives the lower
pull roll.
11. COOLING FAN ON/OFF - Turns the cooling fan
on or off. Push once to turn only the cooling idlers
on, push again to turn only the cooling tubes on,
push a third time to turn both cooling idlers and
cooling tubes on, and push a fourth time for all
cooling off.
