SEL-8310 Remote Fault Reader Operation
Operation

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 R
ADIORANGER 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
