SEL-411L Relay Protection Manual Date Code 20151029
Firmware Upgrade Instructions
Upgrade Procedure
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 Factory Assistance on page P.B.17).
J Verify Relay Settings
Step 1. Prepare to control the relay at Access Level 2; use the
procedure in Enter Access Level 2 on page P.B.8.
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 ACSELERATOR QuickSet Read menu.
If the settings do not match the settings that you recorded
in Backup Relay Settings on page P.B.9, use
ACSELERATOR QuickSet to restore relay settings.
➣ Type SHOW <Enter>.
You can reissue the settings with the SET commands (see
the appropriate SEL-400 series relay section ASCII
Command Reference 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.
K 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
communications 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. If you transfer an invalid CID file, the relay will disable the
IEC 61850 protocol, as it no longer has a valid configuration. To restart
IEC 61850 protocol operation, you must transfer a valid CID file to the relay.
