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).

Controller Information

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.

The upper-left hand section of the BX Home screen

contains status information for four different values,

including outside air temperature, humidity percentage,

season, and light level.

Demand Control Section

Directly below the OAT section is demand control sta-

tus information, which shows the number of applications

and number of loads being shed.

Power Monitoring Section

In the lowest left-hand corner of the BX Home screen

is the power monitoring section, containing active KW

and average power information.

Light Schedules Section

In the center of the BX Home screen is ON and OFF

status information for light schedules.

Air Handling Units Section

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.

tus of the Demand Control application.

The lower right-hand section of the screen shows the

name and current status of time schedules.

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.
