Looking for some advice. I haven't setup a cascading PID loop since a classroom 4yrs ago..
Attached PDF is what I have programmed now. Typical field values are in RED.
SETUP: Booster Pump with Suction Pressure and Discharge Pressure. Want to maintain a Discharge Pressure SP. Suction Pressure only matters if it goes below the Suction Pressure SP, at which point it should ramp the Booster Pump down in an attempt to raise the Suction Pressure. There is also a Low Low Suction Pressure that shuts the Booster Pump down.
