SER D Command
The SER D command shows a list of SER items that the relay has automatic-
ally removed. These are “chattering” elements. You can automatically remove
chattering SER elements in the SER Chatter Criteria category of the Report
settings; the enable setting is ESERDEL. See Section 4: Protection and Logic
Functions, Report Settings (SET R Command) for more information on SER
automatic deletion and reinsertion.
If you issue the SER D command and you have not enabled automatic
removal of chattering SER elements (Report setting ESERDEL), the relay
responds,

SER 1/1/2003 to return all records for January 1, 2003.
