MATelec HydroWHIZ FPC-63243-S4 Mild Steel IP56 Inner Door 3PH 4kW Soft Start Dual Pump Controller

With 400Vac three-phase input and two-pump control, the FPC-63243-S4 provides coordinated operation for level, pressure and temperature systems, with a 4.0kW soft starter assigned to each pump. Adjustable soft start and stop operation provides controlled motor acceleration and deceleration within the HydroWHIZ control system.

The IP56-rated powder-coated mild steel enclosure includes an inner door and removable gland plate. Protection and connection 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. The colour touchscreen HMI provides system status, pump status, alarms and control.

Inputs include 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. Thermal switch inputs are provided for each three-phase pump. The controller also provides visual strobe and mutable audible buzzer alarms.

Two pumps can operate in duty, duty-assist and standby configurations, with adjustable duty sharing and alternation using bumpless transfer. Pump limiting can restrict 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 also includes sleep operation.

The system enable input can enable or disable the system in automatic mode and can be used for auxiliary tank level protection in transfer applications. The HydroWHIZ HMI provides time and date-stamped alarms, logged data, trend graphs and diagnostics. A common-fault volt-free output, 0–10V analogue output mirroring the analogue input, and Modbus RTU Serial RS485 connections for SCADA are also provided.
