3. KEYBOARD AND DISPLAY
The machine interface comprises a yellow Oled display (64 X 128) with black background and 4 buttons named "MODE", "SET",
"+",and "-"; see Figure 12.
The display shows the inverter values and statuses, and indicates the functions of the various parameters.
The button functions are summarised in Table 9.
The MODE button enables the user to move to the next items in the same menu. When pressed for at least 1
sec it enables the user to skip to the previous menu item.
The SET button enables the user to exit the current menu.
This decreases the current parameter (if modifiable).
This increases the current parameter (if modifiable).
When pressed for a longer interval, buttons +/- enable automatic increase/decrease of the selected parameter. If button +/- is pressed
for more than 3 seconds, the automatic increase/decrease speed is increased.
When the button + or – is pressed, the selected value is modified and saved immediately on the permanent memory
(EEprom). Unit shutdown in this phase, even if inadvertent, does not cause loss of the set parameter.
The SET button is only used to exit the current menu and is not used to save any changes. Only in some special cases
described in 6 some values are implemented by pressing "SET" or "MODE"
