1. Introduction
EAGLE is a single phase recloser with an in-built numerical relay for taking the appropriate
decisions during system fault conditions. EAGLE provides a Web-HMI over Wi-Fi which can be
accessed from any handheld device (mobile phones, iPad or laptops). Through the Web-HMI
users can program the recloser, monitor or perform control operations.
EAGLE can be connected to CIM605 Gateway which can download/read data from EAGLE and
send to remote control center. The Gateway also allows user to access Eagle Web-HMI directly.
The Gateway supports DNP3 protocol using which user can monitor and give control
commands to EAGLE.
This document describes in detail the usage of the Web-HMI along with application and
functionality descriptions of the recloser and lists function blocks, logic diagrams (wherever
needed), setting parameters and technical data sorted per function. The document can be used
as a technical reference during the engineering phase, installation and commissioning phase,
and during normal service.
1.1. Intended Audience
This document addresses system engineers, installation and commissioning personnel who use
technical data during engineering, installation and commissioning, and in normal service. The
system engineer must have a thorough knowledge of protection systems, protection
equipment, protection functions and the configurations set in the device. The installation and
commissioning personnel must have a basic knowledge in handling electronic equipment.

2. Powering up the recloser
EALGE is a self-powered device. The energy needed to power up the electronics inside the
EAGLE is harvested from the primary feeder current. The recloser has a Current
Transformer (CT), also called a harvesting CT, which steps down the current flowing
through the feeder and is used to power up the electronics and the movement of the
actuator. The recloser also has a Rogowski coil, connected in series with the harvesting CT,
which is used for measurement of feeder current for protection and control functions.
Since the recloser uses the primary feeder current for energizing, EALGE is powered ON
only if the recloser is in CLOSED position. Once the recloser's vacuum interrupter or circuit
breaker (CB) is closed, a set of capacitors get charged. Once fully charged, the capacitive
energy is used to keep the electronics powered on. Once the primary current is removed,
the electronics can stay powered on for up to 20s. This reserve energy is used to ensure
that the recloser is powered during the auto-reclose (AR) cycle, continue recording events
and ensure a smooth power OFF for the recloser.
2.1. Initial Power up of the recloser
The initial power up of the recloser is done using mechanical handle of the EAGLE. If the
EAGLE is already mounted on the pole, then a hook stick can be used to engage the main
operating handle to close the vacuum interrupter.
Figure 1: EAGLE Open/Close Operation using the Mechanical lever
If the EAGLE is not mounted on the pole and if it can be easily accessed on tablet or a
laptop, then the device can also be powered up through 12V Aux Power Supply adapter.
The interface for connecting the power supply can be seen in Figure 3.

3. Connecting to the recloser through Wi-Fi
Once the recloser is powered up, the EAGLE can be programmed with relevant settings,
monitor the status of the device, download events, DRs, load profiles and perform certain
control operations through a web interface which can be accessed through any handheld
device with a built in Wi-Fi such as a smart phone, tablet or a laptop. The user interface

8
can be accessed through popular browsers such as Google Chrome, Internet Explorer,
Mozilla Firefox or Safari.
Though EAGLE user interface works fine will all of the above-
mentioned browsers, wherever available, Mozilla Firefox is the
recommended option
User connect to the eagle in any handheld device, It can take up to 3
minutes to load webHMI.
Once the EAGLE is powered up, the Wi-Fi chip inside the electronics is activated within
the first 20 seconds. The activation of Wi-Fi is indicated by the flashing of the Lockout
Indicator LED at the bottom of the device. If the recloser has been powered off for an
extended period, the lockout indicator may not blink although the Wi-Fi is turned ON.
In case the Wi-Fi has to be enabled on a device which is already powered up and running,
then the user can toggle the position of the Non-Reclose Mode (NRM) handle (either from
ON->OFF->ON or OFF->ON->OFF) to turn on the Wi-Fi.
Once the Wi-Fi is enabled, the following credentials can be used to connect to the recloser
through the handheld devices.
•Default Wi-Fi SSID for EAGLE : WIFI_RER605_{SERIALNUMBER}
•Default Wi-Fi password : qwerty123
Once the Wi-Fi connection is made in Access point mode, the Web HMI can be accessed
using the url: https://rer605.abb.com/
Please refer to Section 7 to a full explanation regarding Access point
mode.
Once the Web-HMI opens, user will be able to see the Dashboard view in “Viewer” mode.
EAGLE provides role-based access to the settings. Hence the users are required to enter
suitable passwords, depending on their role, to access the Web-HMI. EAGLE supports 4
user roles - “Viewer”, “Operator”, “Engineer” & “Admin” with respectively increasing
authority of access. While the Viewer has limited access to monitor & view status of the
device, the Admin has full access to monitor, program and perform control operations.
The default password format for accessing the Web HMI is “000x”, where x increases from
2 to 4 for “Operator” to “Admin” level of access. Viewer does not need a password.
•Default password for Operator : 0002
•Default password for Engineer : 0003
•Default password for Admin : 0004

9
The user credentials can be entered by clicking on the user icon seen on the top right-
hand corner of the Web-HMI dashboard. This opens up a dialog box where the desired
user credentials can be entered.
Figure 4: Location of for entering user credentials in Web-HMI
It is Strongly Advised to change the SSID & passwords for various roles
before the device is put into service to avoid unauthorized access to the
recloser settings.
For further information on changing/resetting the passwords refer to section 7.4 and 7.5.
After logging with “Admin”, “Operator” or “Engineer” role, if the device
detects no activity over the Wi-Fi for more than 20 mins, then the Web
HMI automatically moves to “Viewer” mode.
3.1. Role-Based Access to Web-HMI features
The access to various features of the device depends on the user credentials used for the
login. The Viewer has only viewing rights with very little control options and “Admin” has
the maximum control on configuring and controlling the device.
The following table shows the access rights based on login credentials.

For the sake of clarity, of this document will describe the features as
available to users with “Admin” credentials.
DeviceAdmin password is used for authentication of DNP3 and HTTPS
messages for communication between LRC and Eagle. This
password is
different from Admin password.
4. Web-HMI Overview
Once logged in, the Web-HMI presents a Dashboard view and other Menu options along
with the status of device Flags. Flags are status information of important events that need
user attention.
4.1. Dashboard overview
The Dashboard of EAGLE Single phase recloser looks as in Figure 5. The Dashboard displays
a Single line diagram (SLD) where the status of the circuit breaker (CB) is displayed. The
RED color of the breaker indicates CB is closed and Green indicates that the CB is open.
Close and Open buttons are provided below the SLD for easy controlling of the EAGLE
circuit breaker.
The Dashboard also displays the fundamental component of the measured primary
current in Amperes, MAC address of the device.
Dashboard provides easy Enable/Disable button for Auto reclose (AR) function, Non-
Reclose Mode (NRM), Cold Load Pickup (CLP) and Operating Mode functionality. Enabling
of each of these functions is shown by “Green” indication and the Disable is shown by
“Grey’ color. Operating mode functionality works only in station mode.
Please refer to Section 7 to a full explanation regarding station mode.
When “Operating Mode” is enabled user will not be able to enable/disable Auto Reclose
function, Non-Reclose Mode, Cold Load Pickup operation using Web-HMI. User will be
able to do these operation through DNP3 only.
Above operation is only possible if LRC and Eagle devices have same
DeviceAdmin password.
If the recloser goes through a complete AR sequence and reaches the Lockout state, it can
be reset using the RESET button on the Dashboard.
The following status information is shown on the Dashboard

The exact view and formatting of the Web-HMI can change based on
the display size of the device used to connect (laptop/mobile/tablet).
Also, some browsers may not display some features based on the
version installed.
Refer to Section 7 for a full explanation regarding Station Mode / Access
Point Mode.
4.2. Configuration
On the left side of the Web-HMI there are Menu options. On clicking each Menu button,
a sub-menu opens presenting different features. The configuration page appears as the
third option on the Menu, but this page allows the user to set the fundamental behavior
of the EAGLE device.
The device has three modes of operation:

14
Auto Recloser
In this mode, device acts like a single phase recloser with
configurable AR & protection functions
Breaker
Reclosing functionality is disabled and the device acts like a
protection relay
Sectionalizer
All protections are disabled and device behaves like a switch
This configuration of device can be made under the Configuration -> General page in
the Web-HMI.
4.2.1. General Settings
The tab Configuration -> General in the Web-HMI is also used to Enable/Disable the
protection functions, set system frequency (50/60 Hz) and also to give a suitable
identifier name to the EAGLE recloser (max 12 characters). The name set here will be
shown in Disturbance Record (DR) file for easy identification of the DR.
In Station Mode, Eagle supports Inter-trip mode & 3 Phase Open Operation both
configurations can be done in Eagle Web HMI by going to “Configuration->General”
(please see figure 7).
Wen a fault occur at any phase then EAGLE device, if the device is in reclose mode, the
unit will perform single phase reclosing and subsequently lockout if it is a permanent
fault. During that time, if it is configured in inter-trip mode enabled, it will send the Trip
message to other 2 Eagles to perform circuit breaker open. It is needed to configure the
Intertrip mode in all three EAGLE Web HMI by going in “General” settings.
In 3 Phase Open Operation mode when the user send an OPEN command via Web HMI
or Scada to any Eagle connected to the LRC the other two eagles will also get open. This
is also an intended operation but to receive 3 Phase Open Operation command we have
enable this in EAGLE Web HMI by going in “General” settings.

15
Figure 7: View of the Configuration-> General tab
The Webpage also allows to configure the device either with Hotline tag
(HLT) or without.
If the device is configured to work without Hot Line Tag, non-reclose
mode is utilized where:
1. Auto reclose is disabled
2. the protection functions trip with settings as set in the Settings
-> Protection page
3. Hot Line Tag settings are ignored.
4.2.2. Sending Settings to Device
Once the desired configurations are made, the button “Save” can be used to temporarily
save the settings in the Web-HMI. The user can then proceed to other sections of the
webpages for configuration. Once all changes are done, the “Send to device” button needs
to be clicked. The settings/configuration changes are then sent to the EAGLE device.
In case the user wants to discard the changes made, “Discard Changes” button can be
pressed. Caution must be exercised when discarding changes as it discards all changes
done even in previously “Saved” but not yet sent to device changes.
The “Save”,” Discard changes” and ‘Send to Device” buttons are seen in all setting pages
of the Web-HMI and their behavior is similar.

16
Only “Saving” the settings will not ensure updating of settings to EAGLE
device. “Send to Device”
must be pressed to send and verify setting
changes in EAGLE.
4.2.3. System Date and Time
EAGLE can sync the device time with two sources, defined as a primary and a secondary
source.
•GPS signal
•System Time from handheld device (Manual)
If GPS is set as the primary source, it is recommended to set the handheld device as the
secondary source (and vice versa). The format of the date, time & time zone can also be
set from this page. The page also displays the time when the last GPS sync was received
for reference. The timestamp and format selected here is reflected in events and records.
Figure 8: System time setting page
If manual is set as primary source , click on “System Date &time” to fetch system time
and time zone. When we click on “Sent to device “ button eagle time will synchronized
with system time. The time is further corrected when the GPS signal is available.
4.2.4. Language selection
Currently EAGLE offers its Web-HMI in only English language, hence there is no
selection.

17
4.3. Monitoring
Monitoring is the first Menu option in the Web-HMI below the Dashboard. Monitoring
menu offers options where user can monitor the device status, events and records.
4.3.1. Self-Supervision
The EAGLE has continuous self-monitoring capability. If any internal errors or
abnormalities are found, they are indicated in the Self Supervision page in the form of an
error code.
The displayed error code can be shared with an ABB technical support person for the
correct diagnosis of the error & subsequent actions.
4.3.2. Events & Fault Records
Event Logs are one of the most important pieces of evidence for post fault system event
investigation. They can provide the reasons for premature equipment failures and give
necessary information to perform post-fault event analysis. Proper use and interpretation
of event records can lead to corrective action for a given system problem resulting in
improved performance and reliability of the distribution system.
The event logging is triggered by the activation and deactivation of protection start, trip,
Binary Input (BI)/Binary Output (BO) status changes, system faults, recloser status changes,
setting changes etc. The logged events are stored in a non-volatile memory and made
available for download as ASCII CSV text file.
Two type of event logs are maintained in the recloser:
1. Internal Events – Events related to device status
2. External Events – Events generated by user activity or protection function
operation
The events can be filtered or searched to see specific entries or only internal (i.e. Device)
or external events. If fault record option is selected, only the protection related events are
filtered. Sorting can also be done by date, event type and description.
The pickup and dropout or assertion and desertion of events are represented by “↑” and
“↓” respectively after the event description text.
Total 100 internal events and 1000 external events will be stored. If the number of events
logged reaches maximum limit, the oldest event will be replaced and overwritten with the
latest event.
All events can be download on to the handheld device. All external events can be cleared
if logged in as an “Admin”. The view of Events page as an “Admin” is presented below.
The detailed list of internal and external events is shown in Appendix 2: List of Events

18
Figure 9 List of Events as seen in “Admin” mode
After Eagle issue the Final Open command latest Event & Fault record
may not be available to download. To download the records, energize
the Eagle and wait until Eagle save the Event and Fault Records in
proper file format.
4.3.3. Live Data
Under this page the live status of measurements, protection functions and supervision
functions are shown. This page also allows configuration of flags. The following information
is displayed:
•Configuration of flags
oLatched : Events which are configured as latched will continue to
hold the status on Web-HMI even after the specific protection function
has reset. This can be used for analyzing the trips/auto reclose shots.
“Reset” button on the dashboard can clear these flags.
oSelf-reset : Events which are configured as self-reset will reset as
soon as the function resets
•Live Measurements
oFundamental primary current in Amperes
oSecond harmonic component of the measured primary current
oTrue RMS value of the primary current
•Over current function trip/pickup status
•Non reclose status & source of activation
•Status of Inrush function
•Status of Sectionalizer
•Alarms from Circuit breaker monitoring function
•Counter value from Circuit breaker monitoring function

19
•Mechanical counter value
•Cold load pickup function status
•GPS based location information (provided GPS signal is available)
Figure 10: Live Data of the EAGLE as seen in “Admin” mode
For every Open operation of the EAGLE, the electro-mechanical counter
displayed on the device is incremented by 1.
4.3.4. Disturbance Recorder
The DR is triggered by activation of protection start, trip or digital signals. Once triggered
it stores the measured current and digital channel information as per user setting into
COMTRADE files, which is made available for download.
Details on the configuration of the Disturbance recorders can be found under the section
4.4.8 on Disturbance Recorder Settings.
The file name for storing the DR will be in the format RER605_DR_yyyymmddhhmmss.(DAT
/ CFG), however in case the file is stored when power is not sufficient in such case the file
name will have additional _r (reduced format) in the file name.
The Web-HMI lists the DRs based on the date and time of recording the DR. The device
supports a maximum of 250 DRs, after which new DRs overwrite the oldest DRs. (if the

20
settings Overwrite Enable is activated in DR settings page) That is, at any given point of
time, the EAGLE device shows the last 250 DRs.
The user will be able to download the DRs individually when logged in as an “Admin”.
Figure 11 Disturbance Records as seen in “Admin” Mode
After Eagle issue the Final Open command latest Disturbance Record
may not be available to download. To download the records, energize
the Eagle and wait until Eagle save the Disturbance Records in proper
file format.
4.3.5. Load Profile
The load profile stores the historic load data captured at a periodic time interval. In EAGLE,
load profile function averages fundamental phase current, RMS current and maximum
RMS current and stores in a non-volatile memory. The value is recorded for an interval of
10 minutes with recording capability of last 90 days. The device will start averaging the
load data once it moves to healthy state and stops averaging once it detects insufficient
power/reboot.
The recloser will record at 10-minute intervals from 00:00 hour time. For example, if the
function is enabled or recloser is powered up at 08:12hrs, the first averaged data point is
recorded at 08:20hrs and first data point will be an average of 8 minutes instead of 10
minutes. Next data point will be recorded after 10 minutes at 08:30hrs. If insufficient
power/reboot is detected after a few hours at 10:35hrs which falls between two 10-minute
intervals, the ongoing data point will be recorded averaged over last 5 minutes.
