MATelec HydroWHIZ FPC-63243-S22 Mild Steel IP56 Inner Door 3PH 22kW Soft Start Dual Pump Controller

For two-pump 400Vac three-phase installations, the FPC-63243-S22 combines HydroWHIZ control with a 22kW soft starter for each pump. Adjustable soft start and stop operation provides controlled motor acceleration and deceleration, with level, pressure and temperature systems managed through the colour touchscreen HMI.

The IP56-rated powder-coated mild steel enclosure has an inner door and removable gland plate. It 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 provide local indication.

A 4–20mA analogue input accepts level, pressure or temperature transducers, while up to 8 digital 24Vdc inputs support 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 two 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 interfaces include a common-fault volt-free output, 0–10V analogue output mirroring the analogue input and Modbus RTU Serial RS485 for SCADA.
