MAIN MENU STRUCTURE
The main menu shows the operational values of the system: pressure, current frequency of the motor, input voltage, output current of the
motor and internal temperature of the inverter. It is also possible to select the language.

DESCRIPTION OF THE PARAMETERS AND SCREEN PAGES
MAIN MENU:
These screen pages are accessible when the device is on. To change pages, press the right and left keys as required.
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 system in "Stand-by" by pressing the central
"on-off" key. In the case of multiple installation with several pumps, simply adjust the master device to switch all connected inverters to
stand-by status.
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.
Language : The language used for the menu and the alarm messages can be selected by the user. Use keys
+ and – to modify the parameter value.
INSTALLER PARAMETERS:
These parameters are present in hidden screens and normally should only be modified during the installation and set-up phases.
To access these pages switch the device to Stand-by and keep the “+” and “-“ keys pressed together
for 5 seconds. On entry to the hidden 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 4 groups:
-
group 0 : pressure parameters
- group 1 : motor parameters
- group 2 : multiple operation parameters
- group 3 : input/output parameters
- group 4 : times
