Figure 3-8: Rear Brake Panel

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- 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. 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- 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.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.
