Introduction and Specifications
Introduction
Locating faults in complex underground distribution systems has always proven
challenging for electrical utilities. Troubleshooting often requires the time consuming
and dangerous tasks of blocking traffic, opening, ventilating, draining, and accessing
subsurface vaults in search of the fault location. SEL’s RADIORANGER™ Wireless
Fault Indication System allows utility personnel to have street-level access to the status
of faulted circuit indicators (FCIs) installed below grade. This system dramatically
reduces the need to access vaults during a patrol, which reduces fault-locating time and
improves personnel safety.
This section covers the following areas:

Product Overview
The RADIORANGER is a wireless fault indication system for locating underground
faults at street level, mitigating the need to access subsurface enclosures to retrieve FCI
status. The RADIORANGER system consists of the SEL-8300 Wireless Interface (a
subsurface radio), the SEL-8310 Remote Fault Reader (a handheld device), and SEL
FCIs that connect to the Wireless Interface to convey FCI status, see Figure 1.1.
A variety of SEL FCIs can be ordered with a magnetic probe output in place of a visual
display. The magnetic probe output connects to keyed ports on the SEL-8300 Wireless
Interface. The SEL-8300 accepts up to 12 FCI magnetic probes, allowing a user to
monitor up to four 3-phase circuits per installation. The SEL-8300 communicates via
the unlicensed 900 MHz band to a handheld SEL-8310 Remote Fault Reader using a
proprietary protocol. The design of the protocol makes communicating with or
interfering with other devices unlikely. Utility personnel use the SEL-8310 to
interrogate multiple Wireless Interface units to determine the status of FCIs installed in

SEL-8300 Wireless Interface
Installation
Introduction
The SEL-8300 collects the status of up to 12 FCIs and communicates this data, upon
request, to an SEL-8310 Remote Fault Reader. Connect SEL FCIs equipped with a
magnetic probe output to the SEL-8300 via a keyed interface. Each magnetic probe
assembly includes a permanent magnet, which activates a Hall-effect sensor inside the
SEL-8300 to indicate the presence of an FCI probe, and two coils that deliver the FCI
trip and reset signals.

SEL-8300 Installation
Securely mount the SEL-8300 using four 1/4 inch-sized (6.0 mm) fasteners (not
included) designed for the surface to which the unit is being attached. To protect the
polycarbonate material of the Wireless Interface, use a flat washer in conjunction with
each fastener. We recommend that you install each fastener with a torque of 25 in/lbs
not to exceed 50 in/lbs. Install the SEL-8300 vertically to ensure optimal integral
antenna position and to maximize the life of the integral lithium battery.
Figure 2.2 SEL-8300 Dimensional Diagram
Standard SEL FCI lead lengths for magnetic probe outputs are 12 feet. Additional lead
lengths can be specified. Mount the SEL-8300 in a location that provides access to all
FCI magnetic probes. The RADIORANGER system communicates via 900 MHz; to
improve the range, install the SEL-8300 in locations with few RF impediments, such as
below a grate, if possible. Additionally, RF performance will be compromised in vaults
where flooding can occur. In vaults where flooding is common or where the FCI lead

length is insufficient for optimal installation, order SEL-8300 units with an optional
remote antenna that provides an extra 15' of lead length. For best results, orient the
omni-directional antenna vertically so that it points toward the surface.
Figure 2.3 SEL-8300 Installed in Underground Vault
Power
The SEL-8300 is equipped with two dials: a power switch and an ID selector. The
smaller dial, labeled PWR, controls the power and has two positions. When the arrow is
pointing up, the SEL-8300 is on. When the arrow is pointing down, the unit is off. The
unit is shipped in the off position to conserve battery energy. The SEL-8300 is powered
by a 20-year shelf life lithium D cell. SEL designed the RADIORANGER system to
optimize battery life without compromising RF range. As such, the SEL-8300 is
expected to provide 15 years of service life under normal operating conditions.
Wireless Interface ID Selection
The larger dial on the SEL-8300, labeled ID, allows the user to select one of eight
wireless interface IDs. The Wireless Interface ID is part of the communications string
between the SEL-8300 and SEL-8310 and identifies which ID(s) the Remote Fault
Reader is communicating with. Therefore, the user should select different IDs if
installing multiple SEL-8300 units within a 150-foot radius. Doing so prevents
communications collisions with the SEL-8310, which could create a source of
confusion for the operator. It is important to situate the ID selector within one of the
eight detent positions in the SEL-8300 housing, to ensure proper ID selection.
Additionally, the ID could serve as a customer-specific naming convention to indicate
the nature of certain installations. For example, certain IDs could represent specific
vault configurations, voltages classes, etc. Another example of a naming convention is
to have odd-numbered IDs represent circuits arranged in a North-South direction, and
even-numbered IDs represent circuits arranged in an East-West direction.

Step 7. If the range is not adequate, move the SEL-8300 to a different
location, possibly a higher point in the vault.
Step 8. If moving the SEL-8300 does not provide adequate communications
range outside of the vault, you may need to order the SEL-8300 with
an external antenna. You can mount the external antenna near the top
of the vault.

Power Requirements
3.2
The SEL-8310 communicates the status of FCIs connected to any SEL-8300 within its
range via LEDs and various audible tones. The front display section labeled Fault
Indication has 12 LEDs arranged in a 4 x 3 matrix. The rows represent Ways 1, 2, 3,
and 4, as read from top to bottom. The columns represent Phases A, B, and C, as read
from left to right. For example, the status displayed in the top left position would
correspond to an FCI monitoring Phase A of Way 1. Each LED corresponds to the
position of each FCI probe installed in the SEL-8300.
Audio annunciation of FCI status is discussed in the manual sections, DIP Switch
Settings and Audio Indication, which follow.
In addition to displaying FCI status, the SEL-8310 also displays its status (ON or OFF)
and battery health through a POWER LED. The INTERFACE LED indicates the relative
health of the SEL-8300, conveying any self-test problems and the lithium battery
health.
The SEL-8300 is equipped with an ID selector dial that allows its radio to
communicate via one of eight IDs. This allows the RADIORANGER system to be used
in locations populated with multiple subsurface vaults within a small geographic area.
The SEL-8310 can display information from up to eight different SEL-8300 units
within range. The SEL-8310 identifies and differentiates each SEL-8300 within range
via a series of LEDs corresponding to each Wireless Interface ID.
Power Requirements
The SEL-8310 is powered from three 1.5 Volt, AA batteries (alkaline or rechargeable).
To open the battery cover, turn the fastener 1/4 turn counterclockwise. You can unhinge
and remove the battery cover to access the battery holder, DIP switches, and
programming header. Insert the batteries according to the polarity noted in the battery
holder. To replace the battery cover, insert the two tabs of the cover under the hinge and
lay the cover flat against the batteries. To secure the battery cover, turn the fastener 1/4
turn clockwise.
DIP Switch Settings
Access the eight-position DIP switch through the battery compartment. Refer to Power
Requirements for instructions on opening the battery cover. DIP Switches 1 and 2
adjust the audio mode of the SEL-8310, while DIP Switches 3 and 4 allow the unit to
operate on a single frequency. Note: Do not adjust DIP Switches 5, 6, 7, and 8. They
should remain in the OFF position.
The SEL-8310 supports four audio modes, selectable via the DIP switch block located
under the battery cover. Tabl e 3.1 describes the four audio modes and the DIP switch
settings used to select them.

The four audio modes are described briefly below. Refer to Audio Indication, for
specific audio indications corresponding to each setting.
Silent Mode—Annunciates Process Status and Button Press information only.
Summary Mode—Annunciates Process Status, Button Press, and FCI Status
Summary information only.
Morse Code Mode—Provides all audio indications. FCI Status Summary
information is followed by FCI Detail information annunciated in Morse
Code.
Row/Column Mode—Provides all audio indications. FCI Status Summary
information is followed by FCI Detail information annunciated in
Row/Column Mode.
All audio indications will be annunciated at the current volume control setting, with the
exception of HMI Adjust Mode indications.
You can configure the SEL-8310 for single frequency operation to allow two
SEL-8310 units to operate within the same area simultaneously, with each unit on a
different frequency. Ta ble 3.2 shows the DIP switch settings that enable this
functionality.
When DIP Switch 3 is in the ON position, DIP Switch 4 determines the single
frequency to be used. If DIP Switch 3 is in the OFF position, then DIP Switch 4 has no
effect. If using two SEL-8310 units in the same area, both units should have DIP
Switch 3 set to ON and one of the units should have DIP Switch 4 set to ON.

P4 in this manual and are annunciated for either a short (50 ms) or long (150 ms)
duration. The tones or sequence of tones are depicted in Figure 3.2–Figure 3.14 and in
Table 3.5.
There are four basic categories of audible annunciation: Process Status, FCI Status
Summary, FCI Details, and Button Press. Additionally, a user can select from four
audio modes: Silent, Summary, Row/Column, or Morse Code Mode. These audio
modes are described in DIP Switch Settings.
Process Status
Process Status events are annunciated to provide feedback of SEL-8310 status. Each
type of event is described below.
Power-Up
The Power-Up event is annunciated after a successful Power On Self-Test (POST) is
completed. It is a series of four tones, three short tones followed by one long tone,
increasing in pitch.
Figure 3.2 Power-Up Audio Indication in All Audio Modes
POST (Power On Self-Test) Fail
The POST Fail event is annunciated if any of the self-tests fail during power up. This is
a single long tone as shown in Figure 3.3.
Figure 3.3 POST Fail Audio Indication in All Audio Modes
Scan Initiate
The Scan Initiate event is annunciated after the {Scan} button is pressed. It is a series of
two short tones, increasing in pitch.

FCI Status Summary
The FCI Status Summary tones provide feedback as to the status of the faulted circuit
indicators connected to an SEL-8300 within range. The pitch and sequence of the tones
indicate whether any or none of the connected FCIs are in the tripped state and no
summary or detail sequence annunciation is already in progress.
Response Received
The Response Received tone will be annunciated during a scan whenever valid data are
received from an SEL-8300 within range. This is a single short tone.
Figure 3.6 Response Received Audio Indication in All Audio Modes
FCI Status Summary—Tripped FCI(s)
The Tripped FCI(s) status will be annunciated if the SEL-8310 receives valid data from
an SEL-8300 with at least one tripped FCI. This annunciation will occur following a
press of the {Next} button, if the next ID contains at least one tripped FCI.

FCI Status Summary—No Tripped FCI(s)
The No Tripped FCI(s) status will be annunciated if the SEL-8310 receives valid data
from an SEL-8300 with no tripped FCIs. This annunciation will occur following a
press of the {Next} button, if the next ID contains no tripped FCI(s). As indicated in
Figure 3.9 and Figure 3.10, the annunciation will vary for most audible modes.

Data Collision
The Data Collision status will be annunciated if the SEL-8310 receives valid data from
two SEL-8300 units set to the same ID. This annunciation will sound after a scan when
the ID containing multiple SEL-8300 units is selected after pressing the {Next} button.
For more information on Data Collision see Scanning for and Retrieving Data from
SEL-8300 Units on page 3.10. This is a set of long tones alternating between two
pitches (high-low, high-low).
Figure 3.11 Data Collision Audio Indication in All Audio Modes
FCI Detail
If a user has configured the SEL-8310 for either Row/Column or Morse Code Modes,
the FCI Detail tones will be annunciated after the FCI Status Summary (see DIP Switch
Settings on page 3.2 for more information). These tones will indicate all of the tripped
phases on the lowest faulted Way. If more than one Way contains tripped FCIs, only the
status of the lowest Way with tripped FCIs will be annunciated.
Morse Code Mode
If the current audio mode is Morse Code Mode, then the FCI Detail audio indication
will consist of the lowest Way that contains one or more faults (1, 2, 3, or 4), followed
by each faulted Phase in the Way (A, B, and C). The Morse Code dot-dash patterns for
all possible Ways and Phases are shown in Figure 3.12.

The {Power} button is located in the top left corner of the SEL-8310. Pressing the
{Power} button causes the unit to enter a Power On Self-Test (POST) and alternates
illuminating all LEDs in solid green, solid yellow, and solid red for 0.75 seconds each.
Provided that the battery voltage is 3.0 Volts or above, it annunciates successful POST
with a four-tone scan. If the battery voltage is below 3.0 Volts, the device will turn off
to prevent damage to rechargeable batteries.

The POWER LED also indicates the relative battery life of the three 1.5 V (alkaline or
rechargeable) AA batteries required to power the SEL-8310, as well as any internal
RAM or Flash memory issues.
➤A solid green LED indicates the voltage is above 3.2 Volts.
➤A solid yellow LED indicates the voltage is at or below 3.2 Volts.
➤A flashing red LED indicates that either the RAM or Flash memory
self-check failed. Return any units exhibiting this annunciation to the
factory for analysis.
Proper Orientation of the SEL-8310
The SEL-8310 is equipped with an integral dipole antenna. To achieve optimal range
with SEL-8300 units mounted below grade, hold the SEL-8310 so that the antenna is
on a parallel plane to the antenna of the SEL-8300, refer to Figure 3.15. If the
SEL-8300 or its remote antenna is mounted properly, the SEL-8310 should be oriented
vertically with the antenna pointing toward the sky. Because of the antenna radiation
pattern, never point the SEL-8310 directly at a manhole or directly toward the location
of the SEL-8300. Doing so will dramatically reduce the range of the radio system and
result in poor performance.
Figure 3.15 Correct and Incorrect Positioning of the Remote Fault Reader
Scanning for and Retrieving Data from SEL-8300 Units
The {Scan} and {Next} buttons are located near the bottom of the SEL-8310. After the
unit is turned on and has successfully completed POST and memory tests, press the
{Scan} button to initiate a scan for SEL-8300 units within range. The Scan Initiate
annunciation, accompanied by pulsing yellow WIRELESS INTERFACE ID LEDs, indicates
the scan sequence has begun.
Date Code 20070301 RADIORANGER Instruction Manual
SEL-8310 Remote Fault Reader Operation

When a scan is initiated, the SEL-8310 clears any previously acquired data. If the
{Scan} button is pressed while a scan is in progress, the SEL-8310 aborts the current
scan and clears all acquired data. The SEL-8310 tests the battery voltage at the start of
each scan and updates the POWER LED as required. The scan sequence ends when one
of the following occurs:
➤A valid response is received for all eight wireless interface IDs.
➤The {Scan} button is pressed, which cancels the current scan and
begins another.
➤15.2 seconds pass after the first valid response from an SEL-8300.
➤The SEL-8310 enters the HMI Adjust Mode.
➤15 minutes pass after the {Scan} button is pressed and no valid
responses have been received.
After a scan is complete, the number of SEL-8300 units within range is depicted on the
SEL-8310 in the Wireless Interface ID section. The first valid SEL-8300 identified
with at least one tripped FCI flashes yellow and its FCI status is depicted in the Fault
Indication section of the SEL-8310. Use the {Next} button to cycle through and
display the status of all SEL-8300 units within range, and their connected FCIs.
Unless multiple SEL-8300 units are installed within a 150-foot range, a user will
probably only receive valid communications with one Wireless Interface per scan. In
vault-dense areas or installations that require multiple SEL-8300 units, a user may be
able to communicate with multiple SEL-8300 units, provided that the ID setting for
each Wireless Interface is not identical. If multiple SEL-8300 units with the same ID
setting are communicating to an SEL-8310, the SEL-8310 will display a collision
notification (see LED Legend—Wireless Interface ID Section). To differentiate between
two SEL-8300 units in this situation, users should move closer to the intended vault
and/or orient themselves between the SEL-8310 and the adjacent vault to exit the range
of, or block the signal of, the adjacent SEL-8300.
If two SEL-8310 Remote Fault Reader units are used in the same proximity, do not
scan both units simultaneously or the communications channel may become unstable.
In this situation, neither Remote Fault Reader may be able to properly communicate
with SEL-8300 units within range. However, two Remote Fault Readers can be used
simultaneously within the same range if the units are in Single Frequency Operation
Mode and are not operating at the same frequency. Please see DIP Switch Settings on
page 3.2 for more information on how to enable this mode.

FCI Data Display
The status of each FCI is communicated to the SEL-8300 via a keyed, wired magnetic
probe interface. Each FCI will send either a Trip (faulted) or Reset (unfaulted) signal to
the SEL-8300 through this magnetic probe interface. The SEL-8300 communicates the
FCI data to the SEL-8310 via 900 MHz radio. The SEL-8310 then displays FCI status
information under the Fault Indication section. A red LED indicates a tripped FCI,
whereas a green LED indicates a reset FCI. By providing both tripped and reset
indications, the RADIORANGER system allows the user to retrieve the status of the
FCIs beyond the fault to validate the fault location.
Low Power Mode
To preserve the battery, the SEL-8310 will enter Low Power Mode one minute after
scan termination or one minute after the last {Next} button press, whichever occurs
later. When the SEL-8310 enters Low Power Mode, all address and FCI Status LEDs
turn off. The POWER LED will emit short pulses, 2.25 seconds apart, in the color in
which the POWER LED was illuminated prior to entering Low Power Mode. While the
SEL-8310 is in Low Power Mode, pressing either the {Scan} or the {Next} button
returns the device to the normal mode and displays the same data that was displayed
prior to entering Low Power Mode. All the data received from the last scan is still
available via the {Next} button. The SEL-8310 will reenter Low Power Mode one
minute after Low Power Mode termination or one minute after the last {Next} button
press, whichever occurs later.
HMI Adjust Mode
Adjust the SEL-8310 volume and brightness to accommodate user and situational
preference. Pressing and holding both the {Scan} and {Next} buttons simultaneously
for one second places the SEL-8310 in the HMI Adjust Mode. In this mode, the FAULT

Adjust Mode five seconds after the last button press or after pressing and holding both
the {Scan} and {Next} buttons simultaneously for one second. Following HMI Adjust
Mode termination, the SEL-8310 reenters Normal Mode. The same data displayed
prior to entering HMI Adjust Mode will be available.
While the device is in the HMI Adjust Mode, the {Scan} button cycles through the four
possible volume levels. The volume level is represented by solid yellow WIRELESS
INTERFACE ID LEDs in a bar chart style from left to right. A single LED bar represents
no volume; four LED bars represent maximum volume, which is the default. Each
{Scan} button press selects the next highest volume level until it reaches the maximum
volume level. At that point, pressing the {Scan} button again takes the unit back to the
lowest volume level. When the SEL-8310 exits the HMI Adjust Mode, any adjustments
made to the volume level are updated in the Flash memory and are active when the
Normal Mode resumes.
While the device is in the HMI Adjust Mode, the {Next} button cycles through three
possible LED brightness levels. The solid yellow LEDs that represent the volume level
also adjust their brightness in response to presses of the {Next} button. Each {Next}
button press selects the next highest brightness level until the maximum level is
reached. At that point, pressing the {Next} button again selects the lowest brightness
level. When the device exits the HMI Adjust Mode, any adjustments made to the
brightness level are updated in the Flash memory and are active when the Normal
Mode resumes.

Testing and Troubleshooting
Introduction
This section provides guidelines for testing and troubleshooting the RADIORANGER
system. Self-tests and troubleshooting procedures are included.
Self-Tests
The SEL-8300 and SEL-8310 perform periodic self-tests to verify proper operation. A
self-test failure of either product is indicated via the Remote Fault Reader LED display.
A flashing red POWER LED indicates an SEL-8310 self-test failure. A flashing red
INTERFACE LED indicates an SEL-8300 self-test failure. Please contact the factory to
service any device indicating a self-test failure.
Troubleshooting the SEL-8300
Troubleshooting issues related to the SEL-8300 are primarily related to system
communication and battery life. Tabl e 4.1 lists common troubleshooting issues and
causes/remedies.
