1. UPPER MIDDLE CLUTCH (REWIND) PER-
CENT WEB FORCE - Indicates the web force
(tension) for this clutch as a percentage of the total
possible tension the clutch can exert. What the
pressure indicator displays will change depending
upon whether the motor is on or off and what mode
you are operating the machine under. With the
motor direction arrows off and the machine in
Automatic Tension mode, the indicator displays the
material web tension you set. Once the motor
arrow is pressed and the machine starts, the com-
puter calculates the appropriate pressure to attain
the required web force based on the roll size. The
indicator then changes to read the actual air pres-
sure (in psi) sent to the clutch/brake. If the machine
is in Manual Tension mode, the indicator reads the
actual air pressure (in psi) sent to the clutch/brake.
2. UPPER MIDDLE CLUTCH (REWIND) PRES-
SURE - Adjusts the clutch pressure up or down.
3. UPPER MIDDLE CLUTCH (REWIND) INDI-
CATOR - Indicates that this set of controls is for
the upper middle clutch.
4. UPPER FRONT CLUTCH (REWIND) PER-
CENT WEB FORCE - Indicates the web force
(tension) for this clutch as a percentage of the total
possible tension the clutch can exert. What the
pressure indicator displays changes depending
upon whether the motor is on or off and what mode
you are operating the machine under. With the
motor direction arrows off and the machine in
Automatic Tension mode, the indicator displays the
material web tension you set. Once the motor
arrow is pressed and the machine starts, the com-
puter calculates the appropriate pressure to attain
the required web force based on the roll size. The
indicator then changes to read the actual air pres-
sure (in psi) sent to the clutch/brake. If the machine
is in Manual Tension mode, the indicator reads the
actual air pressure (in psi) sent to the clutch/brake.
5. UPPER FRONT CLUTCH (REWIND) PRES-
SURE - Adjusts the clutch pressure up or down.
6. UPPER FRONT CLUTCH (REWIND) INDI-
CATOR - Indicates that this set of controls is for
the upper front clutch.
7. MIDDLE FRONT BRAKE PERCENT WEB
FORCE -Indicates the web force (tension) for this
brake as a percentage of the total possible tension
the brake can exert. What the pressure indicator
displays changes depending upon whether the
motor is on or off and what mode you are operating
the machine under. With the motor direction
arrows off and the machine in Automatic Tension
mode, the indicator displays the material web ten-
sion you set. Once the motor arrow is pressed and
the machine starts, the computer calculates the
appropriate pressure to attain the required web
force based on the roll size. The indicator then
changes to read the actual air pressure (in psi) sent
to the clutch/brake. If the machine is in Manual
Tension mode, the indicator reads the actual air
pressure (in psi) sent to the clutch/brake.
8. MIDDLE FRONT BRAKE PRESSURE -
Adjusts the brake pressure up or down.
9. MIDDLE FRONT BRAKE INDICATOR - Indi-
cates that this set of controls is for the middle front
brake.
10. UNWIND/REWIND SHAFT LOCKING SYS-
TEM ON/OFF - Engages/disengages the unwind/
rewind shaft locking system. The switch disen-
gages the locking system with the door either open
or closed with the motor off. The doors must be
shut to engage the system. If the doors are shut and
the unwind/rewind shafts are disengaged, pushing
the motion control engages them automatically.
Note the color coding on each shaft and the shaft
loading tray. Unwinds are marked with blue and
rewinds are marked with red. Always use the cor-
rect shaft in each loading position.
