MATelec HydroWHIZ FPC-63343-(AA-D) Mild Steel IP56 Inner Door 3PH 1.6-13A DOL Triple Pump Controller

Pump staging and destaging are handled by the MATelec FPC-63343-(AA-D) HydroWHIZ, a 400Vac three-phase controller configured for three pumps. 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. Telemetry is supported via a standard BMS common fault volt-free contact and an onboard Modbus RTU RS485 terminal block for SCADA. System protective routines integrate transducer failure protection, cycle count limits, high and low level protection, and a 7-day pump anti-seize program.

Features

• Audible siren output terminal on the control board for integration of remote strobe and buzzer indicators.
• 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.
• Dedicated RS485 serial communication port enabling Modbus RTU telemetry to master PLC networks.
• Removable gland plate to facilitate simple site conduit wiring access.
