Backup Relay Settings
The relay preserves settings and passwords during the firmware upgrade
process. However, interruption of relay power during the upgrade process can
cause the relay to lose settings. Make a copy of the original relay settings in
case you need to reenter the settings. Use either the SEL-5010 Relay Assistant
software or
AC
SEL
ERATOR
QuickSet to record the existing relay settings and
proceed to D. Start SEL
BOOT
. Otherwise, perform the following steps:
Step 1. From the Transfer menu in HyperTerminal , select Capture
Text .
Step 2. Enter a directory and filename for a text file where you will
record the existing relay settings.
Step 3. Click Start .
The Capture Text command copies all the information you
retrieve and all the keystrokes you type until you send the
command to stop capturing text. The terminal emulation
program stores these data in the text file.
Step 4. Execute the Show Calibration ( SHO C ) command to retrieve
the relay calibration settings.
Use the following Show commands to retrieve the relay
settings:
SHO G , SHO 1 , SHO L 1 , SHO 2 , SHO L 2 ,
SHO 3 , SHO L 3 , SHO 4 , SHO L 4 , SHO 5 , SHO L 5 ,
SHO 6 , SHO L 6 , SHO P 1 , SHO P 2 , SHO P 3 , SHO P F ,
SHO R , and SHO T .
NOTE:
Settings classes can vary
among SEL relays. See the relay
instruction manual for a listing.
Step 5. From the Transfer menu in HyperTerminal , select Capture
Text and click Stop .
The computer saves the text file you created to the directory
you specified in
Step 2 under Backup Relay Settings .
Step 6. Write down the present relay data transmission setting
(SPEED).
This setting is SPEED in the SHO P relay settings output. The
SPEED value should be the same as the value you recorded in
A. Prepare the Relay on page B.2 .
D. Start SEL
BOOT
Step 1. Find and record the firmware identification string (FID):
a. From the File menu, choose Properties .
b. Select the Settings tab in the Properties dialog box
( Figure B.4 ).
NOTE:
If the relay does not prompt
you for Access Level 1 and Access
Level 2 passwords, check whether the
relay has a password jumper in place.
With this jumper in place, the relay is
unprotected from unauthorized
access (see the relay instruction
manual).
