    VASCO - VAriable Speed COntroller If the maximum flow rate required is 60 l/min, it is sufficient to use a 6 liter pressure vessel. The pre-charge pressure of the pressure vessel must be approx. 80% of the operating pressure. Example If the set pressure in the inverter is 4 bar, the pre-charge pressure of the pressure vessel should be approx.

  • Page 45: Variable Speed Pumping Unit With One Or Two D.o.l. Pumps

    The D.O.L. pumps should be controlled by special devices that, besides managing the start and stop, also ensure the main protections (overload, dry running). Nastec offers the PILOT device for this purpose. Finally, it is possible to equip the system with more pumps in COMBO mode, and one or two more D.O.L. pumps that intervene when more water is required.

  • Page 46: Electrical Connections

    VASCO - VAriable Speed COntroller The primary pump continues its operation at variable speed according to the instantaneous water demand. In case of reduced demand, the primary pump decreases its frequency and the inverter progressively switches off the D.O.L pump 2 and the D.O.L pump 1. If parameter Alternance is set to ON, the D.O.L.

  • Page 47: Synchronous Operating Principle

    VASCO - VAriable Speed COntroller 11.3.2. Synchronous operating principle. If parameter COMBO synchrony is set to ON, synchronous operation is achieved. This operating mode provides additional energy savings over cascade operation. When water is required, a pump is started at variable speed according to the demand. When the demand increases and the maximum frequency is reached, a second pump is started and the two pumps run at the same speed to satisfy the water demand.
