Integrated Flow Control

Global FC Data Copy

Set Global FC Data Copy to Start on the Manual Over- ride Screen (see FIG. 87). Global copy provides a start- ing point for all recipes, enabling Continuous Learning (see page 76) to take over.

Global copy works very well with multiple colors when the viscosities are similar. It may only require a calibra- tion and global copy each time a regulator is serviced or if restriction downstream of the regulator is changed.

Continuous Learning

The flow profile will automatically adjust as necessary to drive to the required flow set point, reflecting changes in material viscosity or system dynamics (such as restric- tions downstream from the regulator).

When changing recipes, the profile is saved to the cur- rent active recipe. A Job Complete input will also save the profile to the active recipe.

Setting Ki and Kp

FIG. 89 shows the definition and relationship between Ki and Kp.

The default value for Ki is 40.

The default value for Kp is 400.

For most applications, Ki and Kp do not need to change. Do not change these vallues unless you are sure it is required.

Before adjusting these values, ensure that the input fluid pressure to the regulator is pulsation free, and the outlet pressure is higher than 12 psi (.08 MPa, 0.84 bar) for each flow rate set point.

Applications with viscosities less than 20 cps or greater than 300 cps may require that the Ki and Kp be adjusted. Do this by making small variable changes to the values in Advanced Setup Screen 5. See FIG. 88.
