The Speedrive inverter can control more up to 4 pumps, equipped with various Espa solutions, for a multiple
pump booster set control.
a) Booster set with "On-Off" auxiliary pumps , equipped with "ELV" box .
b) Booster set with inverter regulated auxiliary pumps, equipped with "Speedrive" box in slave mode.
Communication is through communication port RS-485.

Sequence of Operation:
Faced with a demand for water, the pump A starts fast enough to meet the need for installation.
-
If the need is beyond the capacity of the pump A, pump B is activated at 100% capacity. The pump A reduce
-
speed to meet demand (exchange rate set according to menu 10.1)
If the need exceeds the capacity of the pumps A + B, the pump C is activated. The pump A reduce speed to
-
meet demand.
And successively...
-
The operation mode is alternated. Each activation of the booster set, the order of start pumps is random. This will
equal the operation hours.

The Speedrive installation and electrical wiring is done as described in this manual.
For installation and connections of the modules "ELV", see its installation manual.
The connection of the pressure transducer must be made solely on the drive Speedrive.
A 2-wire twisted and shielded cable 0.5mm2 section must make the communication between devices.

If the unit works more than 60 seconds at 50Hz, but the pressure does not exceed
0.3 bar, is declared "error for lack of water."
the system will be set to a permanent fault.
Press OK to reset.
