MATelec HydroWHIZ FPC-63243-S18.5 Mild Steel IP56 Inner Door 3PH 18.5kW Soft Start Dual Pump Controller

The FPC-63243-S18.5 combines three-phase 400Vac two-pump control with an 18.5kW soft starter for each pump. Adjustable soft start and stop operation provides controlled motor acceleration and deceleration while the HydroWHIZ system manages level, pressure and temperature applications through its colour touchscreen HMI.

Its IP56-rated powder-coated mild steel enclosure incorporates an inner door and removable gland plate. Protection 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 provided.

The controller accepts a 4–20mA input for level, pressure or temperature transducers 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.

Two pumps can be configured for duty, duty-assist and standby operation, with adjustable duty sharing and alternation and 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 provided. Temperature control includes sleep operation.

The system enable input enables or disables the system in automatic mode and can be used for auxiliary tank level protection. The colour touchscreen 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.
