1. UPPER REAR 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.
2. UPPER REAR BRAKE PRESSURE - Adjusts
the brake pressure up or down.
3. UPPER REAR BRAKE INDICATOR - Indicates
that this set of controls is for the upper rear brake.
4. MIDDLE REAR CLUTCH PERCENT 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 ten-

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. Note that
this clutch (laminate paper rewind) only operates
when the pull roll is down.
5. MIDDLE REAR CLUTCH PRESSURE -
Adjusts the clutch pressure up or down.
6. MIDDLE REAR CLUTCH INDICATOR - Indi-
cates that this set of controls is for the middle rear
clutch.
7. LOWER REAR CLUTCH PERCENT 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 ten-

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. LOWER REAR CLUTCH PRESSURE -
Adjusts the clutch pressure up or down.
9. LOWER REAR CLUTCH INDICATOR - Indi-
cates that this set of controls is for the lower rear
clutch.
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 one 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.
