STA Command (Status)
The STA command displays the status report, showing the relay self-test
information.
To view a status report, enter the command:
=>STA N <Enter>
where:
N = a number (N = 1, 2, 3, ...) that specifies the number of
times to repetitively display the status report. If no
number is entered after the STA command, the relay
displays the status report only once.
