Upgrade Procedure
Step 7. View the front-panel ENABLED LED and confirm that the LED is illu-
minated.
Unless there is a serious problem, the ENABLED LED illuminates
without any intervention, and the relay retains all settings.
If the relay does not enable within five minutes of the
Initial relay restart
message, contact your Technical Service Center or the SEL factory for assistance
(see Technical Support on page B.18).
I Verify Relay Settings
Step 1. Prepare to control the relay at Access Level 2; use the procedure in
Enter Access Level 2 on page B.9.
Step 2. Type VER <Enter> to confirm the new firmware.
Step 3. Match the firmware revision number with the FID number on the
screen.
Step 4. Use one of the following methods to review your settings.
➢ Use the QuickSet Read menu.
If the settings do not match the settings that you recorded in
Backup Relay Settings on page B.9, use QuickSet to restore relay
settings.
➢ Type SHOW <Enter>.
You can reissue the settings with the SET commands (see
Section 9: ASCII Command Reference of the product-specific
instruction manual for information on the SHOW and SET
commands).
Step 5. Type STA <Enter> to check relay status.
Step 6. Verify that all relay self-test parameters are within tolerance.
J Return the Relay to Service
Step 1. Follow your company procedures for returning a relay to service.
Step 2. Type MET <Enter> to view power system metering.
Step 3. Verify that the current and voltage signals are correct.
Step 4. Type TRI <Enter> and then type EVE <Enter> to view the event
report for the event just triggered.
Step 5. Verify that the current and voltage signals are correct in the event report.
Step 6. Autoconfigure the communications processor port if an SEL commu-
nications processor is connected to the relay.
This step reestablishes automatic data collection between the SEL
communications processor and the SEL-400 series relay. Failure to
perform this step can result in automatic data collection failure when
cycling communications processor power.
The relay is now ready for your commissioning procedure.
Verify IEC 61850 Operation (Optional)
SEL-400 series relays with optional IEC 61850 protocol require the presence of
one valid CID file to enable the protocol. You should only transfer a CID file to
the relay if you want to implement a change in the IEC 61850 configuration or
restore the relay CID file after a firmware upgrade in which the CID file is
