3.20. HMI Screen Saver

After 5 minutes of waiting the interface is automatically addressed to the Screen Saver menu. This is an only read menu composed
of 2 pages switched each other every 5 seconds.
During this phase the following parameters are displayed:

String Up
String Dn

String Dn
To exit the Screen Saver menu, it's necessary to press any of four HMI button. The interface will come back to Page [0].

3.21. Generic Controller Operation

The main controller operations available are "Application Save" and "Apply Changes". The first one is used to save the
current configuration of parameters in the UC in order to avoid the possibility to lose it if a power fail happens while the second
one is used for some parameters which require an UC reboot in order to become effective.
These commands can be accessed from menu [24]:

3.22. HMI Parameters Navigation Table

In this table is reported the whole interface structure from main menu to any single parameter including the screen saver pages.
Typically, the HMI is composed by pages, containing the parameters, accessible from Main menu. In few cases there is a two-
level structure where a page contains other pages instead of parameters; a clear example is the page [17] dedicated to Scheduler
management.
