12-38 Standard Event Reports, Sag/Swell/Interruption Report, and SER Date Code 20001006
SEL-351 Instruction Manual
SSI 3/16/97 1/5/97 If SSI is entered with two dates following it (date 3/16/97 chronologically
follows date 1/5/97 in this example), all the rows between (and including)
dates 1/5/97 and 3/16/97 are displayed, if they exist. They display with
the latest row (date 3/16/97) at the beginning (top) of the report and the
oldest row (date 1/5/97) at the end (bottom) of the report. Reverse
chronological progression through the report is down the page and in
ascending row number.
The date entries in the above example SSI commands are dependent on the Date Format setting
DATE_F. If setting DATE_F = MDY, then the dates are entered as in the above examples
(Month/Day/Year). If setting DATE_F = YMD, then the dates are entered Year/Month/Day.
If the requested SSI event report rows do not exist, the relay responds:
No Sag/Swell/Interruption Data
