MATelec HydroWHIZ FPC-63343-S15 Mild Steel IP56 Inner Door 3PH 15kW Soft Start Triple Pump Controller

Three 15kW soft starters are incorporated into the FPC-63343-S15, providing controlled starting and stopping for three pumps on a 400Vac three-phase HydroWHIZ system. The adjustable soft start and stop functions operate alongside the controller's level, pressure and temperature modes.

An IP56-rated powder-coated mild steel enclosure with an inner door and removable gland plate houses the control equipment. 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.

The analogue input accepts 4–20mA signals from 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. Each three-phase pump also has a thermal switch input.

The three pumps can be managed 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 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 included. Temperature control includes sleep operation.

The system enable input allows the system to be enabled or disabled in automatic mode and can provide auxiliary tank level protection. The HMI provides time and date-stamped alarms, logged data, trend graphs and diagnostics. Common fault, 0–10V analogue output mirroring the analogue input and Modbus RTU Serial RS485 connections for SCADA are provided.
