MATelec HydroWHIZ FPC-63443-(AA-D)/BMS Mild Steel IP56 Inner Door 3PH 1.6-13A DOL Four Pump Controller

Four three-phase pumps can be coordinated by the MATelec FPC-63443-(AA-D)/BMS, with 400Vac operation and additional volt-free BMS status outputs. The powder-coated mild steel housing features an inner door that isolates power and control components, a removable gland plate, and a pad-lockable mains power isolator switch. Wear balancing is managed by a duty sharing algorithm that rotates the duty pump based on run hour logs to equalise pump usage.

Designed for a 400Vac supply, the control board governs pump contactors to activate the motors safely. Individual pump protection is provided by standard thermal overloads rated for 1.6-13A, providing thermal overload protection. Low-voltage control circuits operate on a circuit-breaker protected 24Vdc supply, isolating field float switches from high-voltage supply lines.

The module handles distinct pumping types, regulating level empty wet wells, pressure boosting, or temperature control. The control board receives an analogue 4-20mA transducer input alongside up to eight digital inputs for float switches, pressure switches, or thermostats. Multi-pump staging uses a 3-second staggered start delay and a 1-second staggered stop delay to prevent excessive current draw and reduce water surge or water hammer.

The colour touchscreen HMI on the inner door displays real-time system status, logged data, date-stamped historical faults, and analog trend graphs. System faults trigger an integrated visual strobe and a mutable buzzer alarm, with a mute function. The BMS hardware provides individual volt-free outputs to report power status, high level alarms, pump runs, and individual pump faults. System protective routines integrate transducer failure protection, cycle count limits, high and low level protection, and a 7-day pump anti-seize program.

Features

• Microprocessor-controlled board memory that allows full factory parameter reset via HMI menus.
• Removable inner door configuration that isolates high-voltage terminal wiring from HMI controls.
• Circuit-breaker protected low-voltage control circuitry operating on a dedicated 24Vdc supply loop.
• Enclosure ground bonding terminal blocks to provide electrical earthing of the panel assembly.
• Individual pump run volt-free contacts to track separate operating statuses on remote panels.
• Separate pump fault volt-free relay terminals to isolate and report specific pump failures to the BMS.
• DIN-rail mounted BMS terminal strip with standard screw connections for multi-core signal wiring.
