Upgrade Instructions
b. Enter Access Level 2 by issuing the 2AC command.
c. Issue the R_S command to restore the factory default
settings.
The relay will then reboot with the factory default
settings.
d. Enter Access Level 2.
e. Restore relay settings back to the settings saved in
Step 3.
Step 11. Change the baud rate of the PC to match that of the relay prior
to Step 5, and enter Access Level 2.
Step 12. Issue the STATUS command; verify all relay self-test results
are OK.
Step 13. Apply current and voltage signals to the relay.
Step 14. Issue the METER command; verify that the current and
voltage signals are correct.
Step 15. Autoconfigure the SEL-2032, SEL-2030, SEL-2020 port if you
have a Communications Processor connected.
This step re-establishes automatic data collection between the
SEL-2032, SEL-2030, SEL-2020 Communications Processor
and the SEL relay. Failure to perform this step can result in
automatic data collection failure when cycling communications
processor power.
Complete Step 16 only if your relay supports the IEC 61850 protocol.
Step 16. Verify IEC 61850 Operation.
Perform the following steps to verify that the IEC 61850
protocol is still operational after a relay firmware upgrade; if
not, re-enable it. This procedure assumes that IEC 61850 was
operational with a valid CID file immediately before initiating
the relay firmware upgrade.
a. Establish an FTP Connection to the relay Ethernet port.
b. Open the ERR.TXT file.
If the ERR.TXT file is empty, the relay found no errors
during CID file processing and IEC 61850 should be
enabled. Go to Step c if ERR.TXT is empty.
If the ERR.TXT file contains error messages relating to
CID file parsing, the relay has disabled the IEC 61850
protocol. Use
ACSELERATOR
®
Architect
™
SEL-5032
Software to convert the existing CID file and make it
compatible again.
i) Install the A
CSELERATOR Architect software
upgrade that supports your required CID file
version.
ii) Run A
CSELERATOR Architect and open the
project that contains the existing CID file for the
relay.
iii) Download the CID file to the relay.
c. Upon connecting to the relay, A
CSELERATOR Architect
will detect the upgraded relay firmware and prompt you
to allow it to convert the existing CID file to a
NOTE: A relay with optional IEC
61850 protocol requires 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 if new relay firmware
does not support the current CID file
version. 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.
