12.4.2 Read and Edit modes

The menus map (see par. 12.5.1) shows all the pages which can be obtained and how to move between them from the keyboard, in the "READ"
mode (just to read the data) or in the "EDIT" mode (to set the parameters).
Starting from any page displayed, after about 120 sec of inactivity, the default page will be automatically displayed (see par. 12.5.1).
The functions allowed depending on state are:
"READ":
Consultation of the measurements and of the historical data
Consultation of the unit configuration parameters
Consultation of the protection parameters
"EDIT":
Everything allowed in READ mode
Configuration of the unit
Programming of the parameters relative to the protections
TEST Functions of the unit
To access the "EDIT" mode, it is necessary to press the ↵ key on a page with fields which can be edited. A password will then be required to enable
you to switch to the editing mode.
The use of the keys is summarized in the following table:
