MATelec HydroWHIZ FPC-63343-S7.5 Mild Steel IP56 Inner Door 3PH 7.5kW Soft Start Triple Pump Controller

For three-pump applications requiring a 7.5kW soft starter on each pump, the FPC-63343-S7.5 provides three-phase 400Vac HydroWHIZ control with adjustable soft start and stop operation. Level, pressure and temperature system modes are managed through the colour touchscreen HMI.

The IP56-rated powder-coated mild steel enclosure incorporates an inner door and removable gland plate. Protection hardware includes a pad-lockable mains power isolator switch, circuit breaker protected low-voltage control and input circuitry, individual pump isolation, contactor and thermal overload protection of pump motors, and DIN rail-mounted terminal connections. Visual strobe and mutable audible buzzer alarms are included.

A 4–20mA analogue input accepts level, pressure or temperature transducers, with up to 8 digital 24Vdc inputs available for low, stop, start, standby start and high float switches, pressure switches or thermostats, system enable/disable and low flow functions. Thermal switch inputs are provided for each three-phase pump.

Duty, duty-assist and standby configurations coordinate the three pumps, with adjustable duty sharing and alternation using bumpless transfer. Pump limiting restricts maximum flow or power requirements, while staging and destaging controls additional pump operation. Manual control, anti-seize, maximum run, pump cycle, no flow, feedback signal fault, pump overload, thermal switch and high/low level, pressure and temperature protection are supported. Temperature control includes sleep operation.

The system enable input provides automatic system enable/disable control and can be used for auxiliary tank level protection. The HMI provides time and date-stamped alarms, logged data, trend graphs and diagnostics. Standard outputs and communications include common fault, 0–10V analogue output mirroring the analogue input and Modbus RTU Serial RS485 for SCADA.
