Pressure Flow Control Mode

When the Flow Control Override is set to “Pressure”, the system will only drive to the pressure associated with the flow rate request of the saved calibration table. It will not close the loop with the flow meters.

Integrated Flow Control

This mode may be used with a ProMix 2KS connected both to a robot with flow control and to a manual gun. Because there are two flow paths, the meters cannot be used to close the flow loop. Therefore the robot can run a calibration by itself. When calibration is complete, set to “Pressure.” The robot will run in open loop mode, and the manual gun can spray at the same time.

Kp refers to the speed at which fluid flow reaches its set point.

Target Flow Rate

Kp

Ki		Ki refers to the degree fluid flow over shoots its set point.

TI17119a

NOTE: Ki and Kp are dependent on each other. If one changes the other must change.
