NOTE

i
The setting aid Estimated record size is dimmed and thus, you cannot set or change it.
Keep in mind that the estimation refers to typical sinusoidal signals and that the size of a fault record can
increase in the event of distorted signals.
NOTE

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 (_:10741:111) Maximum record time = 3.0 s
With the Maximum record time setting, you configure the maximum recording duration for a 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.
NOTE
i
i
The parameter Maximum record time does not apply to fault records which are tripped by manual trig-
gers ( >Manual start ). For these fault records, the parameter Manual record time applies.
Parameter: Pre-Trigger Time
•
Default setting (_:10741:112) Pre-trigger time = 0.1 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 (_:10741:113) Post-trigger time = 1.0 s
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 (_:10741:116) Manual record time = 1.0 s
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.
