About Active Driver
The Active Driver unit is a comprehensive device that includes hydraulic system connections, a
pressure sensor, a flow sensor and an electronic
frequency converter (inverter).
When fitted to the delivery of each pump, the Active Driver regulates the rotation speed of the electric pump to which it is connected maintaining a constant pressure in relation to the flow rate variation of the water.
The water that flows through the Active Driver also helps to cool the internal electronic components.
When the pressure of the system drops due to water extraction, one pump cuts-in for a few seconds at a reduced speed and based on the
required water extraction.
When the first pump reaches its maximum rotation speed, the second pump starts in cascade. The starting order changes at each cycle. The user can adjust the pressure of the pumps by means of the two + and – buttons on the Active Driver (the pumps are set as standard at the same pressure value).
The pumps cut-out under the following conditions:
• Pump overcurrent
• Dry running
• Low supply voltage
• Max. pressure value exceeded (adjustable)
• Active Driver electronic components
Dual pump groups with Active Driver are supplied along with a safety control unit with magneto-thermal cut-out and power supply input terminal board.
Active Driver Displayed Functions
• Pump operating frequency (Hz)
• Instantaneous pressure (bar)
• Pump absorbed current (ampere)
• Operating alarms
