Espa SPEEDRIVE V2 Installationsanleitung Seite 28

1) GENERAL INFORMATION.
1.1) Description
The Speedrive inverters have been designed to adjust the speed of three-phase motors used with water pumps.
The inverter receives a signal from the pressure transducer that is proportional to the installation's pressure. This
signal is processed and it regulates the speed of the motor to keep the pressure constant, even though the
consumption of water varies.
It can be used with 50Hz or 60Hz motors. Selecting the output frequency with the menu option.
The units have a constant pressure control system. The PI system used provides two numerical constants that are
processed by the unit to achieve a stable regulation.
This type of regulation can greatly reduce the consumption of energy when compared to unregulated systems,
since the consumption of electricity will be proportional to the consumption of water. Another of the advantages
of regulated units is the decrease in voltage surges, softening current peaks and, therefore, increasing the
working life of the pump.
1.2) Plug & Pump
ESD pumps and Espa pressure units are factory pre-configured, with an optimum set pressure for the supplied pump.
No other adjustments are necessary.
With our units regulated using Speedrive technology from ESPA you will enjoy the latest generation of Plug & Pump
pumping systems, ready for optimal pumping operation.
1.3) Dry run protection.
If the unit detects that a pump is not receiving intake water, it will stop and the "DRY RUN" alarm will be activated,
with 3 reset attempts until the unit completely shuts down in order to repair the problem or breakdown in the
intake of this pump.
WARNING: Correct compliance with the installation and operating instructions and the electrical
connection diagrams will guarantee the correct operation of the unit.
DANGER: The failure to follow the instructions in this Manual can lead to motor overloads, diminishment
in technical characteristics, reduction of the unit's working life and all types of subsequent results, for
which we decline any responsibility.
