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).

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.

3.7 Alarms
This section describes how to view and use the Alarm
Advisory Log.
3.7.1 Accessing the Alarm Advi-
sory Log
The Alarm Advisory Log can be accessed by pressing
the alarm icon key on the controller.
3.7.2 Viewing the Controller
Advisory Log
The current number of advisory log entries (the log
that is highlighted) is displayed at the top right of the
Advisory Log Screen. The total number of alarms and/or
notices in the Advisory Log is displayed below the current
field. To move between Advisory Log entries, press the up
or down arrow key.
Figure 3-9 - Alarm Advisory Log
The Advisory Log is divided these categories:
• Date
•Time
•State
• Area Ctrl: Application: Property
•Message
3.7.3 Date and Time
The Date and Time columns simply display the date
and time when the alarm or notice was generated and
logged into the controller.
3.7.4 State
The State column describes the alarm type, the current
alarm state, and whether or not the alarm has been
acknowledged. There are three possible alarm states:
• ALARM - A high-priority warning, usually signify-
ing a condition that requires attention.
• NOTICE - A low-priority message, usually signify-
ing a condition or a system change that requires no
attention or may require attention in the future.
• FAIL - A failure is a special message that signifies a
failure in an E2 system, an application, or in an
input or output device controlled by an application
(such as a sensor or fan).Returned-To-Normal and
Forced-To-Normal Alarms
For as long as the condition that caused the alarm mes-
sage exists, the State field will show either ALARM,
NOTICE, or FAIL as appropriate to the alarm type. How-
ever, if the condition that caused the alarm, notice, or fail-
ure is corrected, the message shown in the State field will
change to signify the correction.
There are two ways an alarm, notice, or failure condi-
tion may be corrected:
• Return-To-Normal - “Return-To-Normal” means
the condition that generated the alarm, notice, or
failure has returned to normal on its own, or the E2
has automatically corrected the condition. If an
alarm returns to normal, a “N-” will appear in front
of the alarm state in the State field.
• Reset (Forced)-To-Normal - “Reset-To-Normal”
means the E2 has been forced by a user to consider
the condition “normalized” for purposes of alarm
control. A Reset-To-Normal occurs when an alarm
is reset using the Alarm Reset button 
(ALARM RST). If an alarm is forced to normal, an
“R-” will appear in front of the alarm state in the
State field.
Table 3-7 lists the nine possible state messages as they
appear in the State field.

Alarms ALARM N-ALM R-ALM
Notices NOTCE N-NTC R-NTC
Failures FAIL N-FL R-FL
3.7.5 Ack/Reset State
The State field also shows whether or not an advisory
record has been acknowledged or reset by a user. If an
alarm has been acknowledged or reset, a dash “—” will
appear at the end of the State field. If an alarm has not
been acknowledged or reset, an asterisk “*” will appear at

Alarms Menus and Set Up Options • 13
the end of the State field.
3.7.6 Area Ctrl: Application:
Property
This column describes where the alarm, notice, or fail-
ure was generated from. Alarms and notices can either be
generated within the E2 system or from an input value that
is higher or lower than an alarm or notice setpoint defined
during the system configuration process.
3.7.7 Advisory Message
The Advisory Message column is a brief description of
the alarm, notice, or failure. Because of screen size con-
straints, it is often the case that the full advisory message
will not be displayed in the Message field. To view the full
advisory message, as well as the alarm priority and other
important alarm information, press (EXPD INFO)
for Expanded Information.
Figure 3-10 - Expanded Info Screen
3.7.8 Acknowledging, Resetting,
and Clearing Log Entries
3.7.8.1 Acknowledging
When an alarm, notice, or failure is acknowledged,
the alarm stays in the Alarm Log, but all annunciation of
the alarm is suspended until the alarm is reset or cleared.
As stated in Section 3.7.5, the state of the alarm or notice
will also change to a dash “—” indicating acknowledge-
ment.
When you acknowledge an alarm, you prevent it from
ever annunciating again in any way until you manually
reset or clear the alarm. A condition that causes an alarm
will never automatically return to normal when it is
acknowledged.
For setting acknowledging permissions, see Section
10.12.1, Changing Required User Access Levels, section
of the E2 Manual P/N 026-1614.
TIPS: ACKNOWLEDGEMENT VS. RESETTING
•Reset an alarm if you believe the condition that
caused it is fixed, but you wish for a new alarm to
occur if the problem happens again.
•YouMUSTreset an alarm that has been previ-
ously acknowledged to re-enable alarming for
the alarm. Failure to do so will cause the alarm
to remain in ACK, and the alarm will not be gen-
erated again. AN ACKNOWLEDGED ALARM
WILL NOT AUTOMATICALLY RESET.
•Acknowledge an alarm to silence alarm panel
horns or lights, ONLY IF technicians have been
notified of the problem and have been dis-
patched. Technicians, after fixing the problem,
MUST reset or clear the alarm to re-enable
alarming.
To acknowledge an alarm or notice, highlight the
desired log entry and press(ALARM ACK). A
screen will come up prompting the user to either acknowl-
edge the selected advisory, acknowledge all advisories, or
to cancel the operation.
•Press
to acknowledge the selected advisory.
• Press to acknowledge all advisories.
• Press to cancel the operation.
3.7.8.2 Resetting
When a log entry is reset, it is forced to a normal con-
dition and the log entry remains in the Controller Advisory
Log.
An alarm, notice, or failure can be reset by highlight-
ing a log entry and pressing (ALARM RST) while at
the Advisory Log screen. A screen will come up prompt-
ing the user to either reset the selected advisory, reset all
advisories or to cancel the operation.
1. Press to reset the selected advisory.
2. Press to reset all advisories.
3. Press to cancel the operation.
3.7.8.3 Clearing
The option to clear logs completely removes a log
entry from the Advisory Log.
Advisory Log entries may be cleared by highlighting
the log entry and pressing (ALARM CLR) while
viewing the Advisory Log screen. A screen will come up

14 • E2 RX/BX/CX I&O Manual 026-1622 Rev 0 12-JUN-2012
prompting the user to either clear the selected advisory,
clear all advisories or to cancel the operation.
1. Press to clear the selected advisory.
2. Press to clear all advisories.
3. Press to cancel the operation.Expanded Advi-
sory Information
Figure 3-11 - Expanded Info Screen
To view expanded information on a log entry, highlight
the desired log and press (EXPD INFO). A screen
will come up telling the user what advisory is being
viewed out of a total number of advisories.
Property or Board/Point
This message shows the location where the advisory
was generated. This will be a board and point address or
an application input or output (in Area Ctrl:Applica-
tion:Property) format.
Advisory Message
The advisory message is displayed below the Property
or Board/Point. The Advisory Message describes the advi-
sory log entry (what went wrong in the system).
Acknowledge Status
Acknowledge Status describes the state of the advi-
sory. If an advisory has been acknowledged or reset, the
user name or the person who acknowledged or reset the
alarm will appear below the acknowledge status. The date
and time when the advisory was acknowledged or reset
will also be displayed below the user’s name.
If the advisory has not been acknowledged or reset,
this field will display an asterisk “*” along with the word
“UNK.”
Report Priority
The report priority fields describe the priority level of
the advisory, as well as the date and time the advisory
occurred.
Return To Normal
If the advisory has returned to a normal state, either on
its own or because of a user-ordered alarm reset, the date
and time on which the reset occurred will be shown beside
the report priority.
3.7.9 Facility Status Display (FSD)
Alarms
The FSD can be used to handle alarms. Information
such as time stamp, alarm ID string, current status, the rea-
son an alarm was triggered, (if a case temp limit was
exceeded) configured priority of the advisory, Return-To-
Normal information, and if available, the limit that was
exceeded can be viewed through the FSD. Alarms cannot
be configured from the FSD unit.
If more than one E2 controller is at a site, one E2 must
be set up as the alarm annunciator for that site. The FSD
will receive alarms from that alarm-annunciator E2 for the
entire site. The FSD will point only to a single E2 at a site
(it will not poll multiple controllers for alarms). For more
information, refer to the FSD Manual (P/N 026-1400).
