Module: Disturbance Recorder
Disturb rec
The disturbance recorder works with 32 samples per cycle. The disturbance recorder can be started by one of
eight start events (selection from the »assignment list«/OR-Logic).
The disturbance record contains the measuring values inclusively pre-trigger-time. By means of Smart
view/Datavisualizer (option) the oscillographic curves of the analogue (current, voltage) and digital
channels/traces can be shown and evaluated in a graphical form.
The disturbance recorder has a storage capacity of 120s. The disturbance recorder is able to record up to 10 s
(adjustable) per record. The amount of records depends on the file size of each record.
The disturbance recorder can be parameterized in the menu »Device Parameter/Recorder/Disturb rec«.
Determine the max. recording time to register a disturbance event. The max. total length of a recording is 10s
(inclusive pre-trigger and post-trigger time).
To trigger the disturbance recorder, up to 8 signals can be selected from the »assignment list«. The trigger
events are OR-linked. If a disturbance record is written, a new disturbance record cannot be triggered until all
trigger signals, which have triggered the previous disturbance record, are gone.
Recording is only done for the time the assigned event exists (event controlled), plus the time for the pre- and
post-trigger, but not longer than 10s. The time for forward run and tracking of the disturbance recorder is shown
in percent of the total recording length.
Example
The disturbance recorder is started by the general activation facility. After the fault has been cancelled
(+ follow-up time), the recording process is stopped (but after 10s at the latest).
The parameter »Auto Delete« defines how the device shall react if there is no saving place available. In case
»Auto Delete« is »active«, the first recorded disturbance will be overwritten according to the FIFO principle. If the
parameter is set to »inactive«, recording of the disturbance events will be stopped until the storage location is
released manually.
