6.1.4 Description of the electronic board (fig. 4)
6.2 Function of the product
ElectronicControl contains an electronic regulation system using pressure and
flow sensors and a frequency inverter.
The electronic regulation system allows to reach a constant pressure in the net-
work whatever the flow is and to minimize the power consumption of the
installation (automatic mode). The pressure will be constant according to the
set point pressure originally preset.
In hand mode the pump can be tested at maximum speed.
In automatic mode the ElectronicControl starts the pump when the installation
pressure (NET P) is lower than the set point pressure (P SET) minus the pressure
gap set (START DELTA P).
The ElectronicControl stops after a time period set (TIME BEFORE STOP) when
the installation pressure (NET P) has reached the set point pressure (P SET) and
when the flow is zero.
The ElectronicControl protects the pump against (Chap 10.2):
• dry running,
• over currents,
• too high water temperatures,
•frost,
• short-circuits,
• over voltages,
•Undervoltages.
In case of defect (such as dry running, overvoltage …), the led blinks and the
ElectronicControl will try to start the pump regularly. After many trials the Elec-
tronicControl finally stops, the led is ON and does not blink anymore.
6.3 ElectronicControl setting
After connection to the pump and to the power supply, the ElectronicControl
will show the model type and the software version for 10 seconds. Then the
ElectronicControl shows the STANDARD display mode.
Then the ElectronicControl has to be set in accordance to the pump character-
istics and to the requirement of the installation, in order to warranty a safe and
efficient operation.
