• Medium = 10s accelerate and 5s decelerate.
• Slow = 20s accelerate and 10s decelerate
2.2. Constant Slave: 1 variable speed pump with controller and up to 2 constant
speed lag pumps (Lag pumps will need a separate starting device)
• APPLICATION TYPE:
• Constant Pressure: Pressure control using a pressure transducer or other
external feedback device with analog signal
• Flow Control: Flow control using a ow meter or other external feedback
device with analog signal
• Level Control: Level control using a level transducer or other external
feedback device with analog signal
• CONTROL UNITS: Select the appropriate control units for the application
(psi, GPM, ft., etc.).
• RAMP TIME: The Ramp Time is the time to transition from stop to full speed.
• Fast = 5s accelerate and 3s decelerate.
• Medium = 10s accelerate and 5s decelerate.
• Slow = 20s accelerate and 10s decelerate.
• NUMBER OF PUMPS: Set the total number of pumps including the variable
speed pump.
• RUN TIME EQUALIZATION: Enabling this parameter will stage and destage
the xed speed pumps to provide equal run time for each xed speed
pump.
• STAGING BANDWIDTH: Set the SBW percentage to accommodate system
pressure uctuation.
• SBW STAGING DELAY: Staging a pump on is delayed by the length of time
programmed.
• SBW DESTAGING DELAY: Destaging a pump is delayed by the length of
time programmed.
