3. Use the ACCESS command and relay password to get to Access Level 1. At the “=>” relay
prompt, issue the IRIG command. IRIG directs the relay to read the demodulated IRIG-B
time-code input on the AUX input power panel port. If the relay reads the time code
successfully, the relay updates the internal clock/calendar time and date and transmits a
message with relay ID string, date, and time. If no IRIG-B signal is present, or the code
cannot be read successfully, the relay sends the error message “IRIG B DATA ERROR”. If
you receive an error message, check the cable connection between the SEL-2020 and the
relay AUX input port and consult the Troubleshooting Subsection in Section 10:
Maintenance of this manual.
Issue the SHOWSET command (SHO for short) to view the relay settings. You should see
relay setting information similar to the following:
