SER (Sequential Events Recorder)
Access Levels 1, B, 2
The SER command displays the last 512 SER records. To limit the number of
records displayed, use number or date parameters with the SER command.
SER d1 shows only events triggered on the date specified by d1. SER d1 d2
shows only events triggered on or between the specified dates. SER m shows
the most recent m events. SER m n shows event records m through n. The
following is an example of the SER report. See Section 9: Event Reports and
SER for a complete description of the report.

SER C (Clear Sequential Events Recorder)

SET (Edit Group 1—6 Settings)
Access Level 2
Configure the relay using the SET command. The entire syntax of the SET
command follows:
SET n Setting TERSE <Enter>
All parameters are optional and perform the following functions:
➤ n specifies the setting group (1 through 6). The default is the
active setting group.
➤ Setting specifies the setting name with which to begin. The
default is the first setting.
➤ TERSE eliminates the display of the group settings at the end
of the setting procedure. The command will function properly
if just TE is entered, instead of the full word.
NOTE: Clear the SER
Buffer With Care.
Automated clearing of the SER buffer
should be limited to reduce the
possibility of wearing out the
nonvolatile memory. Limit automated
SER C commands to once per week or
less.
