SEL-321/321-1 Instruction Manual
if VALID is Y, it is no longer displayed. Execute the SET 1 command to enter the
correct group settings for your application, and set VALID and LOGVAL to Y.
Step 10. Execute the SHO F command and review displayed data. Confirm that the I/O
board settings match those displayed in Step 1. If any I/O board settings do not
match, you must enter the correct settings. Note that some default settings may have
changed.
For example, if the output board configuration settings (IOBRD1 and/or IOBRD2)
do not match the number of output contacts on your relay, you must change the
output board configuration setting. To change the output board configuration
setting, you must enter the Calibration access level by executing the CAL command.
The password for Calibration access level is CLARKE.
Execute the SET F command to change the board configuration settings. Change the
IOBRD1 and/or the IOBRD2 (if equipped with a second output board) settings to
match the output board configuration. Set IOBRD1 = 8 for an 8 contact output board
configuration, IOBRD1 = 12 for a 12 contact output board configuration, and
IOBRD1 = 16 for a 16 contact output board configuration. Enter the output board
configuration setting for IOBRD2 if the relay is equipped with a second output
board.
Note that IOBRD1 refers to the interface board terminating on relay terminals 201
through 240. IOBRD2 refers to the interface board terminating on relay terminals
301 through 340.
Execute the SET L 1 command to enter the correct SEL
OGIC control equations for
your application. Execute the COPY command or the SET and SET L commands
to enter settings for each of the remaining groups (six total).
Execute the STATUS, METER, and TRIGGER commands to ensure that all
functions are operational. Set and record your Access Level 1, Breaker Access
Level, and Access Level 2 passwords and the date and time.
Step 11. With relay communications still established and at Access Level 2, execute the
SHOWSET C command and review displayed data. If data is identical to
previously recorded data of Step 1, you may execute the QUIT command, and the
relay is ready for your commissioning procedure. If, however, any channel gains are
different, you must reenter the previously recorded values by executing the SET C
command (similar to group settings procedure). Make sure VALID = Y (Note:
VALID will only be present in the settings if defaults have been reloaded). After
this procedure is completed and changes have been saved, execute the QUIT
command. The relay is now ready for your commissioning procedure.
Step 12. If a new serial number label is included with the upgrade, attach the serial number
label so the old label is covered.
Step 13. If you have any questions, please do not hesitate to telephone us for assistance.
