Section 2 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.
2.2 SEL-8300 Wireless Interface Installation SEL-8300 Installation 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.
SEL-8300 Wireless Interface Installation SEL-8300 Installation 2.3 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.
2.4 SEL-8300 Wireless Interface Installation SEL FCI Connections i4147a Figure 2.4 SEL-8300 Informational Diagram SEL FCI Connections The interface portion of the SEL-8300 is equipped with 12 FCI magnetic probe interface ports aligned in a 4 x 3 matrix. The rows represent Ways (of a multiway switch) 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.

2.6 SEL-8300 Wireless Interface Installation Testing and Verifying Installation 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.
Section 3 SEL-8310 Remote Fault Reader Operation Introduction The SEL-8310 Remote Fault Reader provides a human-machine-interface (HMI) to utility personnel charged with locating and isolating faulted sections of circuits. The SEL-8310 is a handheld device that communicates wirelessly with any SEL-8300 Wireless Interface within range. Flexible antenna Durable, buoyant case rated to IP54 Remote Fault Reader battery monitor Displays up to eight unique Wireless Interface IDs Easy-to-use keypad Figure 3.
3.2 SEL-8310 Remote Fault Reader Operation Power Requirements 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.
SEL-8310 Remote Fault Reader Operation DIP Switch Settings Table 3.1 3.3 Four Audio Modes Selectable With the DIP Switch Block Audio Mode DIP Switch 1 DIP Switch 2 Silent Mode ON ON Summary Mode ON OFF Morse Code Mode OFF ON Row/Column Mode OFF OFF 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.
3.4 SEL-8310 Remote Fault Reader Operation Audio Indication Audio Indication The SEL-8310 is equipped with a piezospeaker that produces four distinct audible tones to supplement LED indications. The tones are denoted as pitches P1, P2, P3, and 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.
SEL-8310 Remote Fault Reader Operation Audio Indication 3.5 P4 P3 P2 P1 Figure 3.4 Scan Initiate Audio Indication in All Audio Modes Scan Complete The Scan Complete event is annunciated after a scan has completed. This is the same tone sequence that plays at power-up. P4 P3 P2 P1 Figure 3.5 Scan Complete Audio Indication in All Audio Modes 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.
3.6 SEL-8310 Remote Fault Reader Operation Audio Indication 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. P4 P3 P2 P1 Figure 3.

3.8 SEL-8310 Remote Fault Reader Operation Audio Indication For example, in Row/Column Mode, the FCI Detail audio indication annunciated if Way 2 is the lowest Way containing a fault, and with Phases B and C faulted would be: Button Press The Button Press annunciation occurs under any of the following circumstances: ➤ Either the {Scan} or {Next} button is pressed in HMI Adjust Mode (see HMI Adjust Mode on page 3.
SEL-8310 Remote Fault Reader Operation Operation Table 3.5 3.
3.10 SEL-8310 Remote Fault Reader Operation Operation 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.
SEL-8310 Remote Fault Reader Operation Operation 3.11 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.
3.12 SEL-8310 Remote Fault Reader Operation Operation LED Legend—Wireless Interface ID Section Green (solid) LED = Valid communication with an SEL-8300 set to the corresponding ID. All FCIs connected to that SEL-8300 are in the reset (unfaulted) position. Yellow (flashing) LED = The SEL-8300 (corresponding to the ID) is being represented in the Fault Indication section of the SEL-8310. Red (solid) LED = Valid communication with an SEL-8300 set to the corresponding ID.
SEL-8310 Remote Fault Reader Operation Operation Table 3.6 3.
3.14 SEL-8310 Remote Fault Reader Operation Operation correspond to speaker volume and LED intensity. The SEL-8310 will exit the HMI 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.
Section 4 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.
4.2 Testing and Troubleshooting Troubleshooting the SEL-8310 Table 4.1 Troubleshooting the SEL-8300 (Sheet 2 of 2) Issue Possible Cause/Response INTERFACE LED is flashing red on the SEL-8310 If the LED is flashing red during a collision (i.e., SEL-8310 is communicating with two SEL-8300 units), this indicates the SEL-8300 battery is weak. If the LED is flashing red without a collision, it indicates that a self-test has failed. Please consult the factory.
Testing and Troubleshooting Factory Assistance Table 4.2 4.3 Troubleshooting the SEL-8310 (Sheet 2 of 2) Issue Possible Cause/Response Audible annunciation contains a series of tones Device may be in Morse Code or Row/Column Mode. Check DIP switch settings on positions 1 and 2. Poor range between SEL-8300 and SEL-8310 Ensure the SEL-8300 antenna is unobstructed. Ensure the SEL-8310 is oriented properly (antenna is oriented vertically).
