Operation Manual
Distributed busbar protection REB500
Once recording has been started, the complete recording period that has been set is
recorded.
Unlike the bay units, there are no dedicated general purpose input signals for
recording and triggering.

Sorting binary signals
The order of the binary signals in the list can be changed by clicking on the "Signal
iD" column of the respective signal and moving it to a new position. All other
signals are sorted automatically in relation to the signal that has been moved.
The order of the signals in the list is the order in which they are transferred when
uploading disturbance data.
Since circuit-breakers and isolators equipped with two auxiliary
contacts (CLOSE and OPEN) can have more than two statuses
(open, in motion, closed and undefined), the disturbance recorder
does not record their positions. The disturbance recorder and the
evaluation software can only process binary signals (i.e. with two
possible values).
Possible solution: Configure one of the "x.Start DR" signals to be
connected in parallel to the CLOSE auxiliary contact on the isolator.
Trigger operation
Recording commences when at least one of the triggering conditions is fulfilled.
The trigger then remains disabled until the record has been completed and is then
enabled again. You must therefore set the recording period such that all the signals
you want to record can be recorded.
The trigger inputs are scanned every 16 ms. A trigger signal must
have a pulse duration of at least 16 ms to be certain that it will be
detected.
