The E2 Home Screen Logging On and Access Levels • 1
The Operator's Guide is a general overview of the E2
interface, key pad functionality, menus, and more includ-
ing E2 home screens, logging on, navigation, customizing
the home screen, overrides, and alarms. For more informa-
tion, refer to the complete E2 Manual P/N 026-1614.
1 Logging On and
Access Levels
An E2 may be programmed with up to 25 different
users. A user basically consists of a username, a password,
and an access level. Whenever a username and password
are entered during login, the E2 searches the user records
for the username and password. If found, the E2 will log
the user in at the access level configured for the user in the
user records.
The access level determines how many of the E2’s fea-
tures the user may use. The E2 uses four access levels, one
being the lowest, and four being the highest. Table 1-1
gives a description of each level and the capabilities they
have access to.
Table 1-1 - User Access Levels
Level 1 Read-only access. Users may generally
only view status screens, setpoints, and
some system settings.
Level 2 Setpoint and bypass access. Users may
perform all the tasks a level 1 user may,
and they may also change control setpoints
and bypass some devices.
Level 3 Configuration and override access. Users
may perform all the tasks a level 2 user
may, and they may also override system
settings, create new cells, and program
new applications.
Level 4 System Administrator access. All E2 func-
tions are accessible by a level 4 user.
2 Home Screens
2.1 The E2 Home Screen
The Main Status or Home screen (Figure 2-1 and Fig-
ure 2-2) is divided into sections that display the current
status in areas of importance in the system (i.e., for RX:
suction groups, compressor stages active, circuits, con-
densers, sensor control, and for BX: OAT, demand control,
power monitoring, light schedules, zones, AHUs, and sen-
sor control). Time, date, and alarm status are displayed
along the top of the screen. The display is backlit, but
turns off to save energy after a determined amount of time.
Press any key to bring the display back up.
The Home screen acts as a master and default screen
for all the functions of E2 and can be customized accord-
ing to the user’s needs (see Section 3.5, Manual Defrost
and Clean Mode).

Suction Groups Section
The first section of the RX Home screen is the Suction
Groups section located in the top left corner. The large let-
ters have the name of Suction Group 1 along with infor-
mation on compressor stages active, and the current
pressure setpoint. Setpoints, status, percentages of capaci-
ties, and which stages are active for each suction group are
displayed as well. The suction group that is displayed in
the large block at the top left of the screen is the group that
is named alphabetically first of the suction groups.
Circuit Status Section
To the right of the Suction Groups section is the Circuit
Status section. Both the Standard Circuits and the Case
Controllers are listed in this screen. The circuit names,

2• E2 RX/BX/CX I&O Manual 026-1622 Rev 0 12-JUN-2012
their current status, and temperatures are listed.
Condenser Section
This section is located at the bottom left of the screen
and contains information on the status of the condenser,
such as the discharge setpoint and individual fan states.
Sensor Control
Below the Circuits section at the bottom right of the
screen is the Sensor Control section where Control Value
and Command information are displayed.

Located at the top right-hand corner of the BX Home
screen, the AHU section shows the number of AHUs, tem-
perature, state, and ASP information for each.
Zones Section
Directly below the AHU section is the Zones section,
which shows the number of zones, temperature, whether
or not the application is in occupied mode, CSP and HSP.
Sensor Control Section
Sensor Control is at the bottom right-hand corner of
the BX Home screen and contains analog and digital sen-
sors, value, command, and status information.

2.2 Screen Types
Summary Screens
Summary screens let you view status information for
multiple applications of the same type. For example, (Fig-
ure 2-4) is the Circuits Summary screen in the E2 RX con-
troller. This screen shows the name, state, temperature,
setpoint, alarm, refrigeration, and defrost information for
all defined standard and case control circuits displayed. To
see a more detailed status when on an application sum-
mary screen, highlight the desired application from the list
with the arrow keys and press . This will take you to
the Status screen.
Figure 2-4 - Summary Screen (RX-400 Version Shown)
Status Screens
Status screens are real-time views of application func-
tions. They show the current status of all outputs, the cur-
rent values of all inputs, and other important data such as
control setpoints, run times, and whether or not bypasses
or overrides are active.
Each status screen is specially designed to provide a
concise at-a-glance view of how one or more systems are
functioning.
Figure 2-5 - Status Screen (RX-400 Version Shown)
Setup Screens
The Setup utility is the interface used to change set-
tings and setpoints, and define inputs and outputs in the
E2. Figure 10-11 (section of the E2 manual, P/N 026-
1614) shows a typical Setup screen and its primary ele-
ments.
Index Tabs:
Figure 2-6 - Index Tabs (RX-400 Version Shown)
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 3.4, Customizing
the Home Screen).

4• E2 RX/BX/CX I&O Manual 026-1622 Rev 0 12-JUN-2012
• 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:
Figure 2-7 - 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.
