5.2 Starting the interface for the first time
When you start the interface for the first time, the system displays the
Network
setup
page. In normal work condition this page can be accessed only by Level 2
– Administrator users while Level 0 - User and Level 1 – manager users (see the
”5.3 Safety levels” section on page 19) are not allowed. Yet in this first phase as
it is compulsorily necessary to match one actuator at least with the interface,
the system enables also the Level 0 users and the Level 1 users to enter the page
and match the connected devices with the node positions. Once you install one
actuator in the page, after pressing the key and exiting the page, any
further access will be allowed to the Level 2 – Administrator users only.
Otherwise, if no configuration is made, the
Network setup
page will be
displayed again at next power-on.
For complete information on the
Network setup page please refer to the “5.4
Network setup page” section on page 23.
5.3 Safety levels
The interface provides three safety levels. In some cases they restrict the usage
permissions or prevent the users from entering the pages or accessing some
functions available in the pages.
The three levels are:
•
L0 level 0 = User level
;
•
L1 level 1 = Manager level
;
•
L2 level 2 = Administrator level
.
