MATelec HydroWHIZ FPC-63241-(AA-D) Mild Steel IP56 Inner Door 1PH 1.6-13A DOL Dual Pump Controller

Dual-pump operation is managed by the MATelec FPC-63241-(AA-D) HydroWHIZ, with duty sharing and alternation available to coordinate pump operation. Physical safety elements include a pad-lockable mains power isolator switch, an inner door mounting system for HMI hardware, and a removable gland plate for wiring. Active duty sharing rotates pump starting sequences automatically based on accumulated run hours to equalise pump run hours across the system.

Power distribution is rated for 230Vac supplies, utilizing contactors to switch the pump terminals on demand. For thermal safety, the system is specified for an overload selection range of 1.6-13A per pump to protect the pump motor against overload. Input terminals and logic boards operate on an isolated 24Vdc safety control circuit, protected by individual control circuit breakers.

This system operates under level, pressure, or temperature control modes, selectable via HMI setup screens. Users can connect an analogue 4-20mA feedback sensor together with eight digital inputs for low, stop, start, standby start, and high level alarms. Sequenced staging coordinates starting sequences with a 3-second delay between pumps, and a 1-second staggered delay when stopping the motors.

A colour touchscreen HMI displays live system status, historical alarm counts, date-stamped fault codes, and graphical feedback trends. Diagnostic alerts utilize an integrated strobe and an audible buzzer, featuring audible buzzer mute function. SCADA systems communicate over Modbus RTU RS485 terminals on the board, and BMS links utilize a common fault volt-free contact. Software protective routines like pump cycle protection, no flow limits, high and low level protection, and a 7-day pump anti-seize routine enable system safety.

Features

• 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.
• Pad-lockable mains power isolator switch to physically isolate the incoming mains power supply for safe maintenance.
• 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.
