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.

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.

6.18

ITEM NUMBERS AND SCREEN DESCRIPTIONS

The numbers following each screen parameter can be used to change the value using SHIFT, ITEM.

OPERATOR SCREENS

TENSION

Displays current measured tension, setup number and operating mode.

DESIRED TENSION (18)

The tension set point for AUTOMATIC mode and STOPPING mode. 

(Does not appear when taper tension is used).

CORE TENSION (18)

This is the DESIRED TENSION at CORE DIAMETER when taper

tension is used.

MANUAL LEVEL (48)

The output set point percent when in MANUAL mode.

OUTPUT LEVEL

Current output as a percent of maximum.

TAPER PERCENT (20)

Appears only when taper tension is used.  The core tension is reduced

by this percentage as the rewind roll increases to FULL ROLL

DIAMETER.

WEB SPOOL WIDTH (10)

Appears only when inertia comp is used.  Enter the width of the present

web to enable calculation of roll inertia.

PROGRAM-PARAMETER SCREENS

BAR GRAPH TIME (29)

Update time for the tension / output bar graph.

Default is .050 sec.

DERIVATIVE TIME (34)

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.

ERROR LIMIT (19)

This value limits the percent of error that is acted upon.

HOLD LEVEL (26)

The output will stay at this percent level while in HOLD mode.

INTEGRATOR TIME (32)

This time adjusts the response to errors.  Larger values slow down the

response to rapidly changing error.

NUMERIC DISPLAY TIME (28)

Update time for the tension / output digital readout.

OUTPUT LIMIT (21)

The output will not go above this percent of maximum.
