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.
➤ 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.
