Control System

The booster sets are controlled by two differential pressure switches with adjustable settings, via an electrical panel with an analogue electronic board.

Main Functions:

• Sequential start-up of the pumps.
• Cyclic inversion of the pump start-up order after each cycle.
• Protection against dry running.
• Delayed start-up of the second pump if both pressure switches close simultaneously, to prevent abrupt pressure changes and power supply overload.
• ON/OFF control of tank level (via float switch) or supply duct pressure (via differential pressure switch).

Single-Phase Electrical Panel:

• Components: Main circuit breaker, SML electronic board, pump start-up relay, manual-automatic buttons for each pump.
• Signals and Controls (LED indicators): Power presence, low water level/insufficient supply pressure, operation of each pump.
• External Control Devices: Two adjustable differential pressure switches ON/OFF, ON/OFF float switch, or reverse pressure switch.

Three-Phase Electrical Panel:

• Components: Main switch, SA electronic board, fuses, contactor and thermal relay for each pump, transformer with fuses for auxiliary circuit, M-0-T switch for each pump.
• Signals and Controls (LED indicators): Power presence, low water level/insufficient supply pressure, operation of each pump, thermal relay tripped (overload), manual or automatic operation.
• User Interface: Buttons to select manual or automatic control, and to start or stop each pump (manual operation).
• External Control Devices: Two adjustable differential pressure switches ON/OFF, ON/OFF float switch, 3 electrodes for electronic tank level control, or reverse pressure switch.
