Example: MPC system with (4) pumps• Setpoint 0% to 5% = All pumps stoppedOne pump operation from setpoint from 5% to √ (1-pump/4-pumps) = 50%• Two pump operation from 50% to √ (2-pump/4-pumps) =70.7%• Three pump operation from 70.7% to √ (3-pumps/4-pumps) =86.6%• Four pump operation from 86.6% to 100%For staging pumps off the cut-out is 2% less then cut-in. Example:staging from 4-pump to 3-pump operation will occur at 84.6%reference signal.Setting rangeThese settings must be made in connection with open loop:• selection of operating mode Stop• selection of control mode Open loop• setting of setpoint 1, open loop• setting of external setpoint influence• selection of operating mode Normal.Setting via control panelTo set an external control source to control the Hydro MPCbooster system, proceed as follows:1.
