Date Code 20080110 SEL-300 Series Relays Firmware Upgrade Instructions B-17
SEL-387E Instruction Manual
Step 1. From Access Level 2, type INI <Enter> to reinitialize the I/O board(s). If this
command is unavailable, go to CR_RAM, EEPROM, and IO_BRD Fail Status
Messages.
a. The relay asks the following question:
Are the new I/O board(s) correct (Y/N)?
Type Y <Enter>.
b. After a brief interval (as long as a minute), the EN LED will illuminate.
If the EN LED does not illuminate and you see a SEL
BOOT
!> prompt, type EXI
<Enter> to exit SEL
BOOT
. After a brief interval the EN LED will illuminate.
Check for Access Level 0 = prompt.
c. Use the ACC and 2AC commands and type the corresponding passwords to
reenter Access Level 2.
d. Enter the SHO n command to view relay settings and verify that these match the
settings you saved (see Backup Relay Settings beginning on page
B-7).
Note: Depending upon the relay, n can be 1–6, G, P, L, T, R, X, or Y.
Step 2. If the settings do not match, reenter the settings you saved earlier.
a. If you have SEL-5010 Relay Assistant software or
AC
SEL
ERATOR
, restore
original settings by following the instructions for the respective software.
b. If you do not have the SEL-5010 Relay Assistant software or
AC
SEL
ERATOR
,
restore original settings by issuing the necessary SET n commands, where n can
be 1–6, G, P, L, T, R, X, or Y (depending upon the settings classes in the relay).
Step 3. Use the PAS command to set the relay passwords.
For example, type PAS 1 <Enter> to set the Access Level 1 password.
Use a similar format for other password levels. SEL relay passwords are case
sensitive, so the relay treats lowercase and uppercase letters as different letters.
Step 4. Go to H. Verify Calibration, Status, Breaker Wear, and Metering on page
B-17.
CR_RAM, EEPROM, and IO_BRD Fail Status Messages
Step 1. Use the ACC and 2AC commands with the associated passwords to enter Access
Level 2.
The factory default passwords are in effect; use the default relay passwords listed in
the PAS command description in the relay instruction manual.
Step 2. Type R_S <Enter> to restore factory default settings in the relay (type R_S 1
<Enter> for a 1 A SEL-387 or 1 A SEL-352 Relay).
