MATelec HydroWHIZ FPC-63343-S22 Mild Steel IP56 Inner Door 3PH 22kW Soft Start Triple Pump Controller

At 22kW per soft starter, the FPC-63343-S22 is configured to control three pumps from a three-phase 400Vac supply. Each pump has its own soft starter with adjustable soft start and stop, integrated into the HydroWHIZ control system and colour touchscreen HMI.

The IP56-rated powder-coated mild steel enclosure incorporates 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 alarm indication.

The 4–20mA analogue input accepts level, pressure or temperature transducer signals, 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 included for each three-phase pump.

Three-pump duty, duty-assist and standby configurations are supported, with adjustable duty sharing and alternation using bumpless transfer. Pump limiting restricts maximum flow or power requirements, while 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 HMI provides time and date-stamped alarms, logged data, trend graphs and diagnostics. Standard interfaces include common fault, 0–10V analogue output mirroring the analogue input and Modbus RTU Serial RS485 for SCADA.
