MATelec HydroWHIZ FPC-63243-E/BMS Mild Steel IP56 Inner Door 3PH 12-18A DOL Dual Pump Controller

The 12-18A overload variant of the MATelec FPC-63243-E/BMS combines 400Vac three-phase dual-pump control with the additional BMS volt-free output configuration. This panel incorporates a pad-lockable mains power isolator switch, a protective inner door, a removable gland plate for cable routing, and DIN-rail terminals. An integrated duty sharing routine alternates the lead pump position automatically based on operating run hours, equalising pump run hours.

Operating on a standard 400Vac supply, the controller feeds the pump contactors and control circuitry. Overcurrent protection utilizes thermal overload protection adjustable from 12-18A. The main control module and float inputs operate on a low-voltage 24Vdc control loop, backed by dedicated circuit-breaker protection.

HMI parameters configure the controller for level empty, pressure boost, or temperature control applications. Operational feedback is driven by a 4-20mA transducer and up to eight 24Vdc digital inputs for floats or thermostats. Staggered pump initiation separates starts by a 3-second delay to limit current draw, and stops pumps with a 1-second delay to limit water surge.

HMI features include a colour touchscreen displaying system event counts, pump run logs, date- and time-stamped faults, and trend plots. Visual strobe and audible buzzer indicators provide local fault warnings, with audible buzzer mute function. Dedicated volt-free BMS contacts provide remote telemetry for power on, high level, individual pump run, and individual pump fault. Standard software protections include high and low level and pressure protection, and a 7-day pump anti-seize cycle.

Features

• Removable gland plate to facilitate simple site conduit wiring access.
• Integrated real-time clock backed by an onboard coin-cell battery for precise timestamping of system events.
• DIN-rail mounted terminal blocks for neat and organized connection of input sensors and motor cables.
• Termination resistor jumper bridge included on the RS485 communication link for line balancing.
• Dedicated volt-free relay terminal for high level alarm reporting to central building management systems.
• 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.
