SETUPS AND COPY SETUPS

There are six independent setups. Each contains its own complete set of parameters. Switch between setups
only while stopped using SHIFT, 1, etc. Each setup can be calibrated individually as described in Section 4, or
the sensor calibration and parameters in any one setup can be copied to any other setup. Complete setups can
be copied using PROGRAM-COPY SETUPS. COPY SETUPS always copies from a selected setup to the
present setup. You can also copy the factory DEFAULTS to the present setup.
6.17 PROGRAM-SECURITY
PROGRAM-SECURITY can be used to prevent changes to all the programming parameters. When secured,
only values in the operator screens can be changed.

ITEM NUMBERS AND SCREEN DESCRIPTIONS

The numbers following each screen parameter can be used to change the value using SHIFT, ITEM.
TENSION
DESIRED TENSION (18)
CORE TENSION (18)
MANUAL LEVEL (48)

TAPER PERCENT (20)
WEB SPOOL WIDTH (10)
BAR GRAPH TIME (29)
DERIVATIVE TIME (34)

OPERATOR SCREENS
Displays current measured tension, setup number and operating mode.
The tension set point for AUTOMATIC mode and STOPPING mode.
(Does not appear when taper tension is used).
This is the DESIRED TENSION at CORE DIAMETER when taper
tension is used.
The output set point percent when in MANUAL mode.
Current output as a percent of maximum.
Appears only when taper tension is used. The core tension is reduced
by this percentage as the rewind roll increases to FULL ROLL
DIAMETER.
Appears only when inertia comp is used. Enter the width of the present
web to enable calculation of roll inertia.
PROGRAM-PARAMETER SCREENS
Update time for the tension / output bar graph.
Default is .050 sec.
Part of PID control. Gives an output adjustment proportional to the rate
of change of tension error. Error is the difference between the desired
tension and the measured tension.
This value limits the percent of error that is acted upon.
The output will stay at this percent level while in HOLD mode.
This time adjusts the response to errors. Larger values slow down the
response to rapidly changing error.
Update time for the tension / output digital readout.
The output will not go above this percent of maximum.
