SEL-411L Relay Protection Manual Date Code 20151029
Firmware Upgrade Instructions
Troubleshooting
This only affects time stamps recorded and stored by the relay prior to the
firmware upgrade. All time stamps in Demand Metering and Breaker
Monitoring following the firmware upgrade will be UTC time with the local
time offset setting (UTCOFF) and daylight-saving time applied.
No other reports (Event History, Event Summary, SER, etc.) are affected.
Troubleshooting
Resolving Model
Mismatch
When uploading a new firmware file to the relay, SELBOOT checks the relay
model number (for example, 451, 421, 487) to ensure that the firmware being
loaded into the relay is correct for the relay model. If the relay responds with
Transfer failed — Model mismatch when a firmware download is
attempted, it is because the relay model number does not match. This may be
because the firmware file is not correct, or the relay model number stored in
the relay memory was corrupted by an interruption of the file download.
To remedy this problem, first ensure you are sending the correct file to the
relay. Table B.1 shows the file names used for the firmware files. Verify that
the model number in the firmware file matches the model of the relay being
upgraded. After confirming that the file is correct, restart the relay into
SEL
BOOT. Do this by turning the relay off and back on while holding down
the front-panel left and right arrow navigation keys. The LCD will display
SELboot Ryyy once the power cycle is complete. The data rate will reset to
9600 during this process. To increase the data rate to the highest speed
possible on the port, type BAU 115200 <Enter> at the SEL
BOOT prompt (!>)
(see Figure B.5). Switch the port communications parameters data rate to
115200 and verify the SEL
BOOT prompt in the terminal screen. At the
SEL
BOOT prompt, issue a REC OVERRIDE command to the relay. This tells
the relay to bypass the model number check at the start of the firmware upload
process. Once the REC OVERRIDE command is issued, the firmware
upload process can be continued following the procedures in Upload New
Relay Firmware, starting with Step 2.
Resolving Status
Failure Message
Response to STA
Command
If a status failure message is returned in response to the STA command,
perform the following steps.
Step 1. Use the ACC and 2AC commands with the associated
passwords to enter Access Level 2.
Step 2. Type STA C <Enter>. Answer Y <Enter> to the
Reboot the
relay and clear status
prompt. The relay will respond with
Rebooting the relay. Wait for about 30 seconds, then press
<Enter> until you see the Access Level 0 = prompt.
Step 3. Use the ACC command with the associated password to enter
Access Level 1.
Step 4. Type STA <Enter>.
If there are no fail messages and you are using Method One,
click Next in Step 3 of 4 of the Firmware Loader and go to
Verify Relay Settings on page P.B.6.
If there are no fail messages and you are using Method Two, go
to Verify Relay Settings on page P.B.14.
If there are fail messages, continue with Step 5.
Step 5. Use the 2AC command with the associated password to enter
Access Level 2.
