10 Operation

The main menu consists of a "Home Screen" and the other main menu entries, which split up into the
different menu levels. Operating states, e.g. the current operating mode, power, etc. are displayed
on the "Home Screen" (see Section 10.6 "Display Messages (Overview)", page 89).
The menu consists of a main menu and maximum two sub-menu levels (see Section 10.1 "Menu
Structure", page 80).
Use the up and down arrow buttons to navigate through the menu levels. The cyclical arrangement
(wrap around) allows you to scroll both forward and backwards to access the desired menu as
quickly as possible.
Faster access to menus
If you want to access sub-menu "7", go back from step "1" to step "9" instead of going six steps
forwards.
When the desired menu is reached press the <ENTER> key in order to access it. The <ESC> key exits
the menu and puts you one menu level up.
Switching to the "Home Screen" in case of inactivity
If no button is actuated for more than five minutes (inactivity), the "Home Screen" appears.
Backlight
The display backlight is automatically deactivated after a short time of inactivity. You can switch
the backlight back on by pressing one of the four buttons. No settings are changed when you
press the button, this only activates the display illumination.
Button sound
The button sound is switched on by default. In order to deactivate it, set the parameter
"250.04 BeepEna" to Off. If "250.04 BeepEna" is set to "Off", the Sunny Island does not emit
an acoustic signal in the event of disturbances and errors.
Slaves wait for commands from the master
Slave devices must wait for commands from the
master device. The following message is shown in
the display during this time.
The Sunny Island uses an operating concept referred to as "Single Point of Operation". For a
system with more than one Sunny Island, all entries are made on the master. There, you configure the
entire system, confirm events, warnings and errors in the QCG (see Section 8 "Commissioning",
page 69), and perform firmware updates when required (see Section 11.6 "Firmware Update",
page 100).
