Standard Electronic Overload Pump Controller with Single Door

• High level alarm delay - Avoids nuisance alarms causes by water level oscillation
• Smart chirp mode alarms - Alarms automatically silence after 5 minutes if not muted, then chirp every 5 minutes
• Manual control - Manual pump mode with optional 5 minute timeout to revert back to auto mode
• Duty sharing and alternation - Duty pump alternates on pump start and after 30 minutes of continuous running in alternation mode, or after 6 hours of accumulated running in circulation mode (dual pump versions)
• Pump staging and destaging - Second pump is staged into operation on high level float or lag pump pressure switch closing and destaged when no longer required (dual pump versions)
• Staggered pump start - Prevents excessive current draw and reduces water surge (dual pump versions)
• Level control mode - Pump out operation controlled by pump stop, pump start and high level float switches
• Maintain minimum level - Ensures minimum tank level is maintained if pump does not run for 4 hours, and pump stop input is closed
• Pressure control mode - Pressure boost operation controlled by lead pump, lag pump (dual pump versions) and low pressure switches.

• Powder coated mild steel enclosure with removable gland plate
• IP54 rated with single door or IP56 rated with inner door

• Pad-lockable mains power isolator switch
• Low voltage control and input circuitry
• Individual pump isolation (dual pump)
• Wide range electronic overload protection of pumps, built into PCB
• Electronic short and overload protection of strobe & buzzer
• Din rail mounted terminal connections

• Single or dual pump keypad interface:

• • Indicator lights for power on, high & low level alarm, pump run,   pump fault/ overload and prime loss
  • Push buttons for alarm mute/reset, pump auto/off/manual control

• PCB control module with dipswitches for adjusting configuration
• Visual (strobe) and mutable audible (buzzer) alarms

Fault Protection

• Pump overload protection - Shuts down pumps on overload, with automatic duty alternation (dual pump versions)
• Pump anti-seize protection - Runs pumps periodically during low use to prevent seizing
• High level alarm - Can be configured with 15 minute delay and auto reset for stormwater applications, or 5 minute delay and manual alarm reset only for sewage applications
• Low level alarm - Locks out pumps until manually reset, to prevent dry running
• Low flow/prime loss protection - Activates if a pump is running but there is no flow for 2 minutes (if using flow switch in input 1 instead of low level float switch)
• Low pressure alarm - Shuts down pumps if low pressure input closes for 60 seconds.

Typical Applications

• Level control:

• • Submersible sewage
  • Submersible stormwater
  • Water transfer pumping
• Pressure control:

• • Pressure boosting

Modification Options

• Max pump run time protection
• External mute button
• 316 stainless steel enclosure (with inner door only).

• Single phase (230Vac) power supply
• 4x digital 12Vdc inputs for float, pressure or flow switches
• Digital 12Vdc input for additional external mute button
• Standard terminal setup: Low level (not for single door version), pump stop, pump start and high level float switches

• 1 or 2x pump supply outputs
• BMS volt free output for common fault.
