tings and setpoints, and define inputs and outputs in the E2. Figure 10-11and Figure 10-48show a typical Setup screen and its primary elements.

Index Tabs

The ten boxes at the top of the screen labeled C1 through C0 are known as the index tabs. These tabs pro- vide a short index of the screens that are used to set up the current application. The numbers C1 through C0 represent the screen numbers (C1 being screen 1, C2 being screen 2, and so on).

Each of the Setup screens that you may access will

have a name beside its number. But as in Figure 10-11and Figure 10-48for example, you will notice some tabs have names, while others are blank.

As you move through these screens within the Setup Editor, the highlight will move to different tabs to indicate which screen is being displayed.

•Pressing  (PREV TAB) will back-up the order of the screens.

•Pressing  (HOME) at any point will take you to the Main Status (Home) screen.

TIP: To see each screen in a typical setup for the E2 RX controller, start from the Main Sta- tus (Home) screen.

1.Position the cursor somewhere inside the Suc- tion Groups section and press and 

(Setup), or just (SETUP) from the Home screen. The General Setup screen will be dis- played.

2.Press  (NEXT TAB) to move the cursor to Setpoints. The Setpoints Setup screen is dis- played.

3.Press  again and the Inputs Setup screen comes up.

4.Press  a few more times to see the rest of the Setup menu screens. When the C0 tab (MORE) is highlighted, there may be more than one extra Setup screen. Press + 

(zero) to see a list of all Setup screens for that application.

5.Keep pressing  while taking note of the extra screens until C1 is highlighted once more.

These screens (C1 through C0) contain all of the set up information that is associated with the selected suction

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 10-11and 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 10-8shows what each key is used for.
