group.
Blank tabs are inaccessible. There are several reasons
why a tab may be inaccessible (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.
• 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, in Figure 10-11
and Figure 10-48, because Screen 1 is displayed, tab C1 is
highlighted.
The Help Line
The line near the bottom of the screen above the func-
tion key menu is the help line. The help line this time pro-
vides a short description of the selected field, along with
important information such as minimum and maximum
value ranges, and setup instructions.
The Function Keys For Setup
The five boxes at the very bottom of the screen show
the function of keys  through . Most of these
keys retain the same function no matter which field,
screen, or application is selected in a Setup screen. Table
10-8 shows what each key is used for.
After all of the functions of E2 are set up, the next step
is to set the System Configuration, which is basically how
the system is used.
10.18.3 Using the Help Key to get
Property Help
Property Help gives an explanation of the parameter,
input, or output the user has selected.
Pressing the
 key while the cursor is pointing to a
parameter, input, or output opens the Property Help win-
dow. The Property Help window displays documentation
specific to the parameter, input, or output the cursor is cur-
rently pointing to.
