  • Various Pump Modes – Duty/Standby or Backup
    • Duty/Standby- A pump set as Duty/Standby will automatically be available when the system is running. The maximum number of duty pumps running at any one time is limited by the “Duty Pumps” setting, when the number of duty pumps running is reached the balance automatically become standby pumps. If Auto rotation is enabled then the Duty & Standby pumps are re-allocated for each restart.
    • Backup- Pumps configured as Backup take over when a fault has been detected with one of duty/standby pumps.
  • Backup pump options.
    • Backup Spin Settings
      • Spin Interval- Adjustable to occur every x days/hours
      • Spin time- Adjustable for a specified duration
  • Pump Rotation Options:
    • At a specified time each day pump rotation will be initiated.
    • Normal Full Autorotation will occur during any system restart.
    • Fixed Pump Start. The same pumps starts on every restart.
    • Pump with the lowest hours to start next.
  • Configuration Backup and Restore.
    • A complete backup of settings and system configuration including sensor scaling can be implemented at any time and then restored if unconfirmed or doubtful changes have been made.
  • Eight individual set points activated by time or external signal.
    • Each of the extra setpoints can be activated by the activation of an input.
    • Each of the extra setpoints can be activated by a start and stop time from the internal clock.
    • Each one of the timed Set Points can also have one of the Programmable Outputs operating at the same time. Typically used to operate valves for different systems.
  • Specialised Control algorithms that are ultra responsive to minimise overpressure occurrences for critical applications.
    • Pipe Fill Mode- Elimination of water hammer at start-up. 
    • Operator adjustable settings to determine at what point pipe fill should be initiated during a restart.
    • Operator adjustable time for pipe filling which automatically stages all pumps to coincide with the overall time.
    • Automatic resumption of pressure control if pipe was only partially empty.
    • Settings to prevent cavitation during the initial stages of pipe fill or when using turbines or bore pumps it facilitates the movement of water past the motor or bearings.
      • Jump duration- This sets how long it takes for the first pump to get to the jump speed before commencing the actual pipe fill sequence.
      • Jump Final Speed- This specifies the final speed of the first pump after the jump duration time. 
  • Flow Meter Support.
    • Digital output meters
    • Analogue output meters.
      • A digital output pulsed flow meter or Analogue output meter can be connected to log/monitor flow and also used to determine any no flow condition for normal standby mode or faults such as loss of prime.
  • Optional Knob style Set Point adjustment available for ease of use.
  • Programmable Start and Stop times for system operation.
  • Options for zero pump displacement detection-  Fixed Frequency or Pump Shut Off Head.
    • The entry of a Shutoff head allows the minimum pump speed to be automatically calculated from the current set point and is essential for multiset point control when the set points vary dramatically.
    • Fixed minimum pump speed is sometimes desirable to enforce a greater overlap between pumps or preset the change over point between pumps.
    • Accurate zero displacement or minimum frequency is also required to determine when the system should be placed on standby or sleep mode.
  • Relative or fixed pressure settings.
    • Low pressure shut down. This setting can be a fixed or relative a value.
      • Relative mode. The Low pressure will be a percentage of the current set point. As the set point changes the Low Pressure will then change.
      • Fixed mode. Low pressure will remain constant regardless of the current set point.
    • Cut In Pressure, High pressure limit and High pressure shutdown. (Relative settings)
      • These settings are all set as a percentage of the current set point.  The actual value calculated by from the % of set point is also shown to make it easy to use.
  • Optional independent Jockey pump.
    • A full set of independent settings available for Jockey pump operation.
