Firmware Upgrade Instructions
Upgrade Procedure
Firmware is designed to be used with specific relays. A list of relay serial num-
bers is provided as part of the firmware upgrade package. The firmware provided
is for use with the listed relays only. Attempts to upgrade relays not listed might
not be successful and can result in relay failure.
B Prepare the Relay
If the relay is in service, follow your company practices for removing a relay
from service. Typically, these practices include disabling input and output control
functions.
C Save Settings and Other Data
It is possible for data to be lost during the firmware upgrade process. Follow the
steps in this section carefully to ensure that important data are saved.
Enter Access Level 2
NOTE: Once serial port
communication is established, it is
recommended to set the port SPEED
setting to the highest possible port
speed available (typically 57600 bps
in Access Level 2). This will reduce the
time needed to read settings and
events from the relay.
Step 1. Using the communications terminal, at Access Level 0, type
ACC <Enter>.
Step 2. Type the Access Level 1 password and press <Enter>.
You will see the Access Level 1 => prompt.
Step 3. Type 2AC <Enter>, and then type the correct password to go to
Access Level 2.
You will see the Access Level 2 =>> prompt.
For more information, see Making an EIA-232 Serial Port
Connection on page 3.4.
Backup Relay Settings
The relay preserves the settings and passwords during the firmware upgrade pro-
cess. However, if relay power is interrupted during the firmware upgrade process,
the relay can lose the settings. Make a copy of the original relay settings in case
you need to reenter settings.
Use one of the following methods to backup relay settings.
➤ If you have not already saved copies of the relay settings, use
QuickSet to read and save the relay settings.
See Create and Manage Relay Settings on page 2.9.
➤ Alternatively, you can use the terminal to download all the relay
settings.
See the FILE READ command under FILE on page 14.27.
For file retrieval procedures see Reading Oscillograms, Event
Reports, and SER on page 3.48.
➤ If you have IEC 61850 configurations and you have not already
saved copies of the CID file, use Architect to read and save the CID
file. See Verify IEC 61850 Operation (Optional) on page B.13 for
details.
DStart SELBOOT
Step 1. Establish/confirm binary transfer terminal communication.
Use a terminal program that supports 1K Xmodem transfer protocol
to communicate with the relay.
NOTE: In addition to all of the
normal settings classes, log in to
Access Level C and save the
SET_CM.TXT file.
