345 TRANSFORMER PROTECTION SYSTEM – QUICKSTART GUIDE
Before upgrading firmware, it is very important to save the current 345 settings to a file on
your PC. After the firmware has been upgraded, it will be necessary to load this file back
into the 345 . Refer to Downloading and Saving Setpoints Files for details on saving relay
setpoints to a file.
Loading new firmware into the 345 flash memory is accomplished as follows:
1.
Connect the relay to the local PC and save the setpoints to a file as shown in
Downloading and Saving Setpoints Files.
2.

EnerVista SR3 Setup software now prepares the 345 to receive the new firmware file.
The 345 front panel will momentarily display "SR BOOT PROGRAM Waiting for
Message," indicating that it is in upload mode.

the new firmware file has been transferred and the upgrade status. The entire transfer
process takes approximately 10 minutes.

The EnerVista SR3 Setup software will notify the user when the 345 has finished
loading the file. Carefully read any displayed messages and click OK to return the
main screen. Cycling power to the relay is recommended after a firmware upgrade.
