  • Page 18: Installation For Differential Constant Pressure Applications

    5.2 Installation for differential constant pressure applications The inverter can manage the pump speed in order to keep constant the pressure difference between the dischage and suction side of the pump in circulation systems. To do this, it is usually installed a differential pressure sensor. Alternatively, it is possible to use two identical pressure sensors: one in suction side and one in discharge side of the pump.

The calibration process must be performed during the final electrical configuration of the system, i.e. with the motor, the cable and any filter applied. If there is any variation of the motor, cable or filter applied, it is necessary to repeat the calibration process by accessing the motor parameters menu (default password 002).
