1. Set Control Type mode:
1.1 Pump speed control: directly
regulation of the speed in
absence of pressure sensor;
security stop for minimum flow
and dry working conditions,
only with manually re-start.
1.2 Single Pump pressure control
1.3 Master-Slave Group
functioning for the absolute
pressure control by RS485
serial bus
1.4 Differential pressure control for
a single pump: dP=P2 (outlet)
– P1 (inlet);
1.5 Differential pressure control in
group by RS485 serial bus;
5 Pumps Number: Number of
pumps (for group functioning
mode 1.3 or 1.5)

Number
Alarm Type Description
1 Current Peak Immediately stop probably caused by short-circuit
Automatic re-start; final stop after 10 consecutive occurrences
2 Over-Voltage Normally caused by over voltage pick supply. Automatic re-start;
final stop after 10 consecutive occurrences
3 Inverter Temperature Over temperature IGBT protection (90°C)
Automatic re-start; final stop after 10 consecutive occurrences
