Main screen page: when Nettuno is operating correctly, the first line of the
display shows the instantaneous pressure detected by the system and the
current frequency of the motor. The lower line of the display shows the
current status of the inverter (Operation/Stand-by/Slave). From here, it is
possible to scroll through the main menu using the arrows, or put the
When Nettuno is in stand-by, the pump will not start up even if the pressure

drops below the value set. To quit stand-by, press the central key again.
Voltage and temperature screen: this menu screen enables the user to
view the voltage on inverter input and the internal ambient and IGBT power
module temperatures. The values of these temperatures contribute to the
intelligent power management, which limits the value of the maximum
frequency of the motor when the pre-alarm thresholds are reached.
Currents screen: this screen displays the phase currents of the motor. The
value of the output current to the motor may differ from the value of the
input current as the inverter modulates both frequency and voltage

menu, use the"<<" and ">>" keys to scroll the pages and the "+"
and "-" keys to change the parameters. To return to the main page
press the central key.
The parameters are divided into 5 groups:
these pages switch the device to Stand-by and keep the "+"
- group 0 : pressure parameters
- group 1 : motor parameters
- group 2 : multiple operation parameters
- group 3 : input/output parameters
