MATelec HydroWHIZ FPC-63343-S4 Mild Steel IP56 Inner Door 3PH 4kW Soft Start Triple Pump Controller

Three-phase 400Vac control and three 4.0kW soft starters define the FPC-63343-S4 configuration, providing controlled starting and stopping for three pumps through the HydroWHIZ platform. Adjustable soft start and stop operation is combined with level, pressure and temperature control through the colour touchscreen HMI.

The IP56-rated powder-coated mild steel enclosure features 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 controller provides a 4–20mA analogue input for level, pressure or temperature transducers and 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. Each three-phase pump also has a thermal switch input.

Three pumps can operate in duty, duty-assist and standby configurations, 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 included. Temperature control provides sleep operation.

The system enable input enables or disables the system in automatic mode and can provide 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.
