Firmware Upgrade Instructions
Upgrade Procedure
J Return Relay to Service
Step 1. Open the terminal window using the Terminal button in the lower
left portion of the Firmware Loader.
Step 2. Use the ACC command with the associated password to enter Access
Level 1.
Step 3. Issue the ID command and compare the firmware revision (Rnnn or
Rnnn-Vy) displayed in the FID string against the number from the
firmware envelope label. If the numbers match, proceed to Step 5.
Step 4. For a mismatch between a displayed FID and the firmware envelope
label, re-attempt the upgrade or contact SEL for assistance.
Step 5. If you use the Breaker Wear Monitor, type BRE <Enter> to check
the data to see if the relay retained breaker wear data through the
upgrade procedure. If the relay did not retain these data, use the
BRE W command to reload the percent contact wear values recorded
in D Save Settings and Other Data on page B.4.
Step 6. Apply current and voltage signals to the relay.
Step 7. Type MET <Enter> or use the QuickSet HMI to verify that the cur-
rent and voltage signals are correct.
Step 8. Use the TRI and EVE/CEV commands or Tools > Events > Get
Events menu in QuickSet to verify that the magnitudes of the current
and voltage signals you applied to the relay match those displayed in
the event report. If these values do not match, check the relay settings
and wiring.
Step 9. Autoconfigure the SEL communications processor port if you have
an SEL communications processor connected to the relay. This step
re-establishes automatic data collection between the SEL communi-
cations processor and the relay. Failure to perform this step can result
in automatic data collection failure when cycling communications
processor power.
Step 10. Follow your company procedures for returning a relay to service.
Method Two: Using a Terminal Emulator
These instructions assume you have a working knowledge of your PC terminal
emulation software. In particular, you must be able to modify the serial commu-
nications parameters (data speed, data bits, parity, and similar parameters), dis-
able any hardware or software flow control in the computer terminal emulation
software, select a transfer protocol (1K Xmodem, for example), and transfer files
(send and receive binary files).
The programs (firmware) that run in the SEL-400 series relays reside in Flash
memory. To load new firmware versions, follow these instructions. SEL-400
series relays have two programs that you may need to upgrade: the regular, or
“executable” program and the SEL
BOOT program.
A Obtain Firmware File
The firmware file is usually provided on a CD-ROM. Locate the firmware file on
the disc. The file name is of the form Rnnn4xx or Rnnn-Vy4xx, where Rnnn is the
firmware revision number, Vy indicates the point release number, 4xx indicates
the relay type, and .s19 or .z19 is the firmware file extension. Copy the firmware
file to an easily accessible location on the PC.
