Change Relay Settings
The Change Relay Settings option allows changes to the TCC curve settings for the selected
fault interrupter. There is a prompt for the input for each setting.
Step 1
After each prompt, enter the new setting and press the Enter button. The available choices
are shown in parenthesis. To retain the previous selection shown after the “ = ” , press the
Enter button.
Step 2
After all of the settings have been entered, the new settings will be displayed in a table.
Enter “Y” for the
Yes option or “N” for No option after the “Save Changes (Y/N)?” prompt. A
confirmation of the choice will be shown and the settings will be displayed. Note that when
new settings are saved, the event report discussed in “View Event Report” on page 10 will be
reset.
