With the accuracy of pressure-sensing level transmitters and the simplicity of float inputs, the BB4000 is the ideal controller for your application. This quad pump controller is easily configured for either analog sensors of float discrete inputs.

Standard Features

• Field configured for floats or analog sensor inputs, including 20VDC loop power.
• Optional 4 analog sensor inputs or 18 discrete (float switches).
• Alternates pumps and performs lag pump delay(s).
• Provides high and low alarms with full front panel.
• Adjustable parameter values.
• Optional VFD speed control output.
• Pump up (fill) or pump down (empty) control.
• 6 Amp pump relay outputs and alarm outputs.
• Display up to 255 feet.
• Full front panel setup for all control options and menu items.
• 120 VAC input power. Line rate and transient protection.
• Isolated and transient protected (4-20mA) analog level input.
• RS-232 serial port. Modbus Protocol. RTU or ASCII mode.
• First ON - First OFF, or First ON - Last OFF alternation.
• Alternator logic skips disabled pumps, remembers lead pump position during outage.
• Timed (1 minute) level simulation.
• Security code protected parameter setup.
• Status of discrete inputs may be viewed from front of control.
• Phoenix-style connectors used.
• Adjustable lag pump(s) delay.
• High and Low level alarm relays and alarm indication.
• Wet well level analog input zero and span adjustments.
• Alternation Schemes (menu selectable):
  -Standard alternation
  -Pump 1 always lead - stays ON with other pumps
  -Pump 1 always lead - turns OFF with other pumps ON
  -Split alternation - pumps 1 & 2 and pumps 3 & 4
  -Fixed sequence - Pump always lead
  -Stepped ON/OFF - only one Pump runs at a time
• 18 discrete inputs, programmable for the following functions:
  -Pump disable with HOA in OFF, or pump fault
  -External alternator selector switch
  -All pump disable (for connection to Phase Monitor)
  -Limit number of pumps called while on emergency power
  -alternation by External time clock
  -Freeze wet well level during a bubbler tube purge
  -Call Pump last
  -Float switch backup
  -A variety of telemetry functions
