Clearing SER Event Report Buffer
If the
SER C
command is entered, the relay prompts the operator for confirmation:
Clear SER Buffer
Are you sure (Y/N)?
If “Y” is entered, the relay clears the SER event reports from nonvolatile memory. If “N” is
entered, no reports are cleared, and the relay responds:
Canceled
The process of clearing SER event reports may take up to 30 seconds under normal operation or
longer if the relay is busy processing a fault or protection logic.
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.
