In addition to the normal bay unit binary signals, there are up to ten general purpose input
signals that can be configured for recording and for triggering the disturbance recorder
(16705... 16750_Start DR_x).
Central Unit
Some binary output signals can be recorded (see the following list). For this purpose, they
must be configured for recording and identified by their signal labels.
• 41305_Trip BB zone41305_Trip BB zone
• 41815_Diff. current alarm
• 42305_BBP trip
• 42330_Check Zone Operated
• 46705_DR general started
Up to 32 signals can be selected for recording. Triggering can take place on the lagging or
leading edge of a signal. If both edges is selected, both lagging and leading edges are active
(see Figure
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.
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.

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 (that is 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.
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.
