BASIC DESCRIPTION AND OPERATION OF BOOSTER
CONTROLLER
HMI Manual Max Speed (Hz) ‐ Max speed (Hz) the VFD’s can operate when
set used as Manual Control operation via HMI.
Note - VFD keypad must be
in Auto On for manual control through HMI.
Max and Min Speed VFDs ‐ Maximum speed VFD can operate when in
Auto On mode and Controller is in operation.
Reduce Speed on No Flow: If ON and no flow is detected, will stop pumps
under normal operation.
Reduce Speed on Pump Limit: If ON and when pump is unable to
reach pressure and in no flow, then set pressure will reduce until pressure
is met and pumps turn Off.

Auto Detect is factory default and preferred operation
Stop and Start Set points are set to minimum predicted speed when
pump
is no longer working efficiently.
Stop and Start Delay ‐ Adjusted for system operation
Manual Start Speed, must be set before Manual Stop Set point.
Manual Stop Set point must be = < Manual Start Speed.
Speed to Start Lag must be set no > 59.5Hz
Speed
Start Lag must be set = > Start Speed.
? ‐ Will take you to Information Screen.
Ramp speeds set at Factory. Minimum adjustment for system operation
may be
necessary to fine tune system operation.
Ramp Limit ON- Lead and Lag Ramp Decel/Accel: Modifies ramp speed
when sudden low or high demand occurs. Lead and Lag set to same level in
normal operations.
Current Limit ON ‐ Deceleration on Limits will be activated
when current or min suction has been exceeded. Once activated, it
will
reduce power to pump from Drive.
Motor FLA and Min. Suction for pump operation.
Time Delays to Reduce Speed: Delays Lead and Lag normal pump turn
off
sequence.
Reaction Time: PLC Real-time delay for operations.
Lead Pump Decel must be = > Lag Ramp Decel. Lead
Ramp Accel must be = > Lag Ramp Accel.
? ‐ Will take you to Information Screen.
Current values will indicate settings as tested at Factory.
Setpoint = Discharge set point taken from Basic Screen 1.
Min to Start = Minimum Discharge Setpoint, Basic Screen 1.
Max Setpoint ‐ Adjusts for Suction changes.
Adj SP ‐ Adjusts for Suction changes.
Adj Min to Start ‐ Adjusted for system variables running outside of normal
conditions.
? ‐ Will take you to Information Screen.
