Firmware Upgrade Instructions
Upgrade Procedure
A Obtain Firmware File
NOTE: The Firmware Loader can be
used to load only relay firmware
(Rnnn4xx). If you need to upgrade
relay SEL
BOOT firmware, use Method
Two.
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, where Rnnn is the firmware
revision 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.
Firmware is designed to be used with specific relays. A list of relay serial
numbers is provided as part of the firmware upgrade package. The firmware
provided is for use with the listed relays only. Attempts to upgrade relays not
listed might not be successful and can result in relay failure.
B Remove Relay From Service
Step 1. If the relay is in use, follow your company practices for
removing a relay from service. Typically, these practices
include disabling input and output control functions.
Step 2. Apply power to the relay.
Step 3. Connect a communications cable and determine the port speed.
If using the EIA-232 front port to upgrade firmware, determine
the port speed as follows:
a. From the relay front panel, press the ENTER (ENT)
pushbutton.
b. Use the arrow pushbuttons to navigate to
SET/SHOW.
c. Press the ENTER (ENT) pushbutton.
d. Use the arrow pushbuttons to navigate to
PORT.
e. Press the ENTER (ENT) pushbutton.
f. Use the arrow pushbuttons to navigate to the relay serial
port you plan to use (usually the front port, Port F).
g. Press the ENTER (ENT) pushbutton.
h. Use the arrow pushbuttons to navigate to
Communication Settings.
i. Press the <Enter> key to view the selected port
communications settings. Write down the value for
each setting.
j. Once the port settings have been recorded, press the
<Esc> key four times to return to the
MAIN MENU.
k. Connect an SEL-C234A EIA-232 serial cable, SEL-C662
USB-to-232 converter, or equivalent communications
cable to the relay serial port and to the PC.
C Establish Communications With the Relay
Use the Communications > Parameters menu of ACSELERATOR QuickSet
to establish a connection using the communications settings determined in
Step 3. See the PC Software section of the relay instruction manual for
additional information.
