Due to the internal administration data, the complete flash memory size for the storing of recordings is not
available. The Estimated record size is user information in order to be able to estimate how many
recordings can be stored in the reserved flash memory. The actual size of the fault record depends on the
degree of compression and the number of stored events.
Parameter: Maximum Record Time
•
Default setting (_:10081:111) Maximum record time = 2 minutes
With the Maximum record time parameter, you set the maximum record time for an individual fault
recording. When the time configured expires, an ongoing fault recording is canceled. This parameter merely
limits the duration of the fault recording.
The maximum record duration includes the pre-trigger time.
Parameter: Pre-Trigger Time
•
Default setting (_:10081:112) Pre-trigger time = 5.0 s
With the Pre-trigger time parameter, you configure the pre-trigger time for an individual fault
recording. The pre-trigger time defines that time before a trigger event.
NOTE
i
i
The Pre-trigger time must be a maximum of 10 % of the Post-trigger time , as otherwise,
DIGSI 5 reports an inconsistency.
Parameter: Post-Trigger Time
•
Default setting (_:10081:113) Post-trigger time = 1 minute
With the Post-trigger time parameter, you configure the post-trigger time for an individual fault
recording. The post-trigger time defines that time after dropout of the trigger event.
Parameter: Manual Record Time
•
Default setting (_:10081:116) Manual record time = 1 minute
The parameter Manual record time determines the length of a recording if the fault recording is acti-
vated dynamically (edge-controlled) via a separately configured input signal
NOTE
i i
The pre-trigger time, the post-trigger time, and the maximum record time have no effect in this case.
Parameter: Averaging Time
•
Default setting (_:10081:140) Averaging time = 1 period
With the Averaging time parameter, you determine the number of periods for which an average value will
be generated and stored in the memory.
The average value is always formed over the entire averaging time.
NOTE
i
i
The actual record time can differ from the parameterized record time since the actual record time is deter-
mined by the parameterized averaging time. The longer the averaging time, the larger the deviation can
be.
