The relay captures a wide variety of events and stores the last 512 in non-volatile memory.
See Event Records on page 6–20 for details. A single power system disturbance could
conceivably fill half of the event recorder due to the various events that can be captured.
Also, some events may happen on a regular basis as part of a control scheme (e.g. Power
Factor events in a capacitor bank switching scheme). For this reason, certain event types
can be 'filtered' from the event recorder to save room for other events. The following
setpoints describe the events that can be filtered.
The setpoint "Record Date/Time Events" should be set to "Enabled" to record date/time
synchronization only when such events occur no more than once per hour. A date/time
event recording rate greater than once per hour will cause flooding of the Event Record
and will, in turn, wear out the EEPROM. This will eventually generate the self-test warning
"Self-test warning: EEPROM corrupted," resulting in the EEPROM having to be replaced.
Ideally the date/time should be recorded no more than twice a day.
