SER Row
Triggering
The relay triggers (generates) a row in the SER report for any change of state
in any one of the elements listed in the SER1, SER2, and SER3 trigger
settings. The factory default settings are:
SER1 = 87A1, 87B1, 87C1, 87A2, 87B2, 87C2
SER2 = 50P1, 50A1, 50B1, 50C1, 50A2, 50B2, 50C2
SER3 = 51PT, 51AT, 51BT, 51CT, 51GT, 51QT
The elements are Relay Word bits from the first 13 rows of
. Any assertion or deassertion of a listed element triggers a row in
the SER report. For example, setting SER1 contains:
Differential element pickups (87A1, 87B1, 87C1)
CT open-circuit detection (87A2, 87B2, 87C2)
Thus, any time one of these elements picks up, times out, or drops out, a row
is triggered in the SER report.
Also, if the relay is newly powered up or a settings change is made, a row is
triggered in the SER report with the message “Relay newly powered up or
settings changed.”
Each row in the SER report contains date, time, current, relay element,
optoisolated input, and output contact information.
Making SER
Trigger Settings
Each SER trigger setting (SER1, SER2, or SER3) can be set with up to 24
elements (see
). Thus, up to 72 elements can be
monitored altogether for SER report row triggering.
The SER settings can be made using spaces or commas as delimiters between
elements. For example, if setting SER1 is made as follows:
SER1 = 51P1,51G1 51P1T,,51G1T , 50P1, , 50P2
The setting displays as:
SER1 = 51P1 51G1 51P1T 51G1T 50P1 50P2
Retrieving
SER Rows
The latest 512 rows of the SER report are stored in nonvolatile memory. Row
1 is the most recently triggered row, and row 512 is the oldest. These lines are
accessed with the
SER
command in the following different ways:
