MATelec HydroWHIZ FPC-63243-S11 Mild Steel IP56 Inner Door 3PH 11kW Soft Start Dual Pump Controller

With an 11kW soft starter allocated to each of its two pump outputs, the FPC-63243-S11 provides three-phase 400Vac HydroWHIZ control with adjustable soft start and stop operation. The controller supports level, pressure and temperature system modes through its colour touchscreen HMI.

The IP56-rated powder-coated mild steel enclosure is fitted with an inner door and removable gland plate. Protection and connection equipment 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.

The controller accepts 4–20mA level, pressure or temperature transducer signals and provides up to 8 digital 24Vdc inputs 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.

The two pumps can operate in duty, duty-assist and standby configurations, with adjustable duty sharing and alternation and bumpless transfer. Pump limiting restricts maximum flow or power requirements, while pump staging and destaging manages 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 HydroWHIZ HMI provides time and date-stamped alarms, logged data, trend graphs and diagnostics. Standard interfaces include a common-fault volt-free output, 0–10V analogue output mirroring the analogue input, and Modbus RTU Serial RS485 for SCADA.
