The "main menu" has a typical menu structure.
Additional submenus are displayed on the left-hand side. All se-
lectable submenus are displayed in a frame. A black background
indicates the current cursor position. The bottom line displays
the current real time, which can be adjusted using the "Settings"
menu.
On the right-hand side, the current key function is represented as
a symbol which is displayed in a small framed area. You can navi-
gate using the "<" and ">" keys to select the required submenu.
Use the ENTER key to open the submenu. You can use the "?"
key to call up the "Help" menu, which provides descriptions for all
the keyboard symbols that are available.
7.3.3 Operating Display
You can call up the "Operating display" from the main menu.
If the DOU has not been used for some time, the system auto-
matically switches back to the operating display, no matter which
menu it is in.
The LCD background illumination is switched off if no further op-
erations are carried out and the system is not in an abnormal
status. In the event of a unit fault, the background illumination re-
mains switched on until the fault is acknowledged. If the inverter
is in night mode, the content of the LCD is cleared and "Sleep
mode" is displayed instead. The background illumination is also
switched off.
You can reactivate the DOU by pressing any key.
