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, for example, the current operating mode, power, etc. are
displayed on the "Home Screen" (see Section 10.6 "Display Messages (Overview)", page 88).
The menu consists of a main menu and maximum two sub-menu levels (see Section 10.1 "Menu
Structure", page 78).
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.
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.
Faster access to menus
If you would like to access sub-menu "7", navigate backwards from "1" over "9", instead of six
steps forwards.
Switching to the "Home Screen" in case of inactivity
If you do not press any buttons for more than five minutes (inactivity), the "Home Screen" is
automatically displayed.
Backlight
The backlight of the display 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 "250.04 BeepEna"
parameter to Off. If "250.04 BeepEna" is set to "Off", the Sunny Island does not give an
acoustic warning signal in the event of interferences 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.
