APPENDIX A: FIRMWARE VERSIONS
DETERMINING THE FIRMWARE VERSION IN YOUR RELAY
To find the firmware revision number in your relay, view the status report using the serial port
STATUS command or the front-panel STATUS pushbutton. For firmware versions prior to
April 7, 2000, the status report displays the Firmware Identification (FID) label:
FID=SEL-300G-Rxxx-Vxxxxxxxxxx-Dxxxxxx
For firmware versions with the date code of April 7, 2000, or later, the FID label will appear as
follows with the Part/Revision number in bold:
FID=SEL-300G-Rxxx-Vxxxxxxxxxx-Z001001-Dxxxxxxxx
The firmware revision number is after the “R” and the release date is after the “D”. The string of
x’s after “SEL-300G” is the firmware part number and depends on the features ordered with the
relay (see SEL-300G Relay Ordering in Section 1).
For example:
FID=SEL-300G-R204-V00H425XX4X-Z001001-D20000407
is firmware revision number 204, base generator protection, 8 outputs, 125/250 V power supply,
wye or delta, 5 A CTs, 125 Vdc control inputs, release date April 7, 2000.
