tings and setpoints, and define inputs and outputs in the
E2. Figure 10-11 shows a typical Setup screen and its pri-
mary elements.
Index Tabs:
The 10 boxes at the top of the screen labeled C1
through C0 are known as the index tabs. These tabs pro-
vide you with a short index of the screens that are used to
set up an application. C1 through C0 represent the screen
numbers (C1 being screen 1, C2 being screen 2, and so
on.) Press the
key and the number of the index tab
(next to the C) and the cursor highlights that index tab.
Each of the Setup screens that you may access will
have a name beside its number. In Figure 10-11, for exam-
ple, you will notice some tabs have names, while others
are blank. This is because there are only four screens in the
Setup for this particular application; C3 is not an accessi-
ble screen.
There are several reasons why a tab may be inaccessi-
ble (i.e., without a name next to the number):
• The tab (and the corresponding screen) is unused
and reserved for later revisions.
• The screen may only be accessed when running in
Full Options mode (see Section 12.2, Logging On
and Access Levels).
• The screen may require one or more fields to be set
to certain values before the screen may be accessed.
For example, a screen containing nothing but com-
pressor proof input definitions might be hidden if
there is a field on another screen that tells the sys-
tem there are no proof checking devices on the
group’s compressors. To access this screen, you
would have to set this field to YES.
The screen you are currently in is always highlighted
in the screen’s index tab. For example, because Screen 1 is
displayed, tab C1 is highlighted.
As you move to other screens within Setup, the high-
light will move to different tabs to indicate which screen
will be displayed.
Header Icons:
At the very top of every screen in the E2, there are
icons that indicate various stages of activity, number of
users logged into the controller, battery alerts, connectivity
status, and more.
