MATelec HydroWHIZ FPC-63341-(AA-D)/BMS Mild Steel IP56 Inner Door 1PH 1.6-13A DOL Triple Pump Controller

Three-pump control on a 230Vac supply is provided by the MATelec FPC-63341-(AA-D)/BMS, with BMS outputs extending the panel's status and fault reporting. The enclosure layout includes a protective inner door for touch safety, a removable gland plate to simplify cable entry, and a pad-lockable mains power isolator switch. Load sharing logic alternates the active duty pump upon system start or after continuous runs, helping equalise pump run hours.

The panel connects to a 230Vac power supply, distributing switching power to the connected pump motor terminal connections. Motor winding protection is provided by thermal overloads adjustable within the 1.6-13A range, protecting the pump motor against overload. Field switch lines and logic circuits operate at 24Vdc to isolate remote sensors, backed by circuit-breaker protection on the control lines.

Flexible setup options include level empty and fill, pressure boosting, or temperature control. System states are governed by a 4-20mA analogue transducer signal and up to eight digital inputs representing start, standby, and alarm conditions. To minimize water surge and line current draw, pumps are staged sequentially with a 3-second staggered start delay and a 1-second staggered stop delay.

Live operating diagnostics are accessible on the colour touchscreen HMI, which plots analogue trends and logs pump start and run hours. Local alarms activate an onboard visual strobe and a mutable audible buzzer, with audible buzzer mute function. BMS hardware features include dedicated volt-free relay outputs for power on, high level, pump run, and individual pump faults. Mechanical protection is provided by high and low level protection, feedback signal fault protection, cycle protection, and a 7-day pump anti-seize routine.

Features

• Integrated real-time clock backed by an onboard coin-cell battery for precise timestamping of system events.
• DIN-rail mounted terminal blocks for neat and organized connection of input sensors and motor cables.
• Termination resistor jumper bridge included on the RS485 communication link for line balancing.
• Pad-lockable mains power isolator switch to physically isolate the incoming mains power supply for safe maintenance.
• Individual pump run volt-free contacts to track separate operating statuses on remote panels.
• Separate pump fault volt-free relay terminals to isolate and report specific pump failures to the BMS.
• DIN-rail mounted BMS terminal strip with standard screw connections for multi-core signal wiring.
