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.
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.
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.

Target Flow Rate
Kp
Ki refers to the degree fluid flow over shoots its set point.
Kp refers to the speed at which fluid flow reaches its set point.
NOTE: Ki and Kp are dependent on each other. If one changes the other must change.
