10-2 Event Reports and SER Date Code 20010731
SEL-352-1, -2 Instruction Manual
When the 50FT label displays in SELOGIC
®
control equations or in the SER report, the alias of
“FAULT_CURRENT” is used.
Use words common for your company to develop alias names to make your SER report easy to
read. Use as many as 15 continuous letters, numbers, and/or the underscore character (no spaces
or other characters are allowed). The relay converts all letters to uppercase.
LABEL
The SER report header includes the LABEL setting. As many as 59 keyboard characters can be
entered in the LABEL setting. The relay converts all lower-case letters to upper case.
SER1–3
The SER1, SER2, and SER3 settings define what Relay Word bits trigger the SER report. Refer
to SER triggering later in this section.
Port Settings (SET P Command)
AUTO
Reports such as short event summaries display automatically for certain conditions. There is an
AUTO setting for each serial communications port that determines if these automatic messages
display. Refer to Automatic Messages in Section 8: Serial Port Communications and
Commands for further information on the individual reports. If AUTO is set to “Y” or “YES”
for a port, the automatic messages display on that port.
EVENT REPORTS (EVE)
Each triggered event consists of two separate reports. The EVE command displays the X-side
voltages, currents and standard digitals; the EVE A command displays the Y-side voltages and
an alternate set of digitals. The header of each event report gives the date and time stamps of the
trigger condition and relay identification. Each event report contains unfiltered analog
measurements and selected digital relay logic elements. The relay reports event type, system
frequency, and voltage nulling calculations just before the settings. A listing of the settings
appears at the end of each report for verification.
The relay stores 64 samples per cycle of unfiltered data. Display options allow you to view the
event in a 4-, 8-, 16-, or 64-sample per cycle format, and to display 1 to 60 cycles of data
depending on the LER setting.
