2.6 Event filtering
It is possible to disable the reporting of events from all interfaces that supports setting
changes. The settings that control the various types of events are in the “record control”
column: see settings in the P74x/EN ST section.
The “record control” setting is used to:
− clear events logs, fault records and alarm events,
− enable or disable event generation for any change in relay output, logic input, general
and protection events or fault and maintenance record.
− display DDB signals.
Note that some occurrences will result in more than one type of event, e.g. a battery failure
will produce an alarm event and a maintenance record event.
If the Protection Event setting is enabled a further set of settings is revealed which allow the
event generation by individual DDB signals to be enabled or disabled.
For further information regarding events and their specific meaning, refer to relay menu
database document (P74x/EN MD).
