Step 12. The relay illuminates the Relay Enabled front-panel LED if the relay
settings were retained through the download. If the Relay Enabled
LED is illuminated, proceed to Step 13. If the Relay Enabled LED is
not illuminated or the front-panel display says, “STATUS FAIL
EEPROM FAILURE,” reload the relay settings using the procedure
below.
a. Set your communications software settings to 2400 baud, 8 data
bits, 1 stop bit.
b. Enter Access Level 2 by issuing the 2AC command.
c. Issue the R_S command to restore the factory default settings in
the relay. The relay will then reboot with the factory default
settings.
d. If the message, “Calibration settings lost, please call the
factory!” appears during the restart, please contact the factory.
(See Factory Assistance on page 10.13.)
e. Enter Access Level 2.
f. Issue a STA command and verify that relay status is OK.
g. Set the relay clock and calendar using the DATE and TIME
commands.
h. Set the Relay, Port, and SER settings using the SEL-5010
software or the following commands: SET, SET P F, SET P R,
SET R.
i. Set the relay passwords via the PAS command.
Step 13. Set your communications software settings (baud rate, number of
data bits, number of stop bits) to agree with the port settings of the
SEL-701 Relay.
Step 14. Execute the STATUS command to verify all relay self-test results are
okay.
Step 15. Apply current and voltage signals to the relay. Issue the METER
command; verify that current and voltage signals are correct. Issue
the TRIGGER and EVENT commands. Verify that current and
voltage signals are correct in the EVENT report.
Step 16. If an SEL-2020 or SEL-2030 Communications Processor is
connected to the SEL-701 Relay, re-auto-configure the SEL-20x0
port. This step will prevent a future auto-configuration failure of the
SEL-20x0 when its power is cycled and the new SEL-701 Relay
firmware does not match the original configuration.
The relay is now ready for your commissioning procedure.
