• Number of records n: The maximum recording time available is divided by this setting into n equal
time periods. For example, assuming 3 records have to be made, then 6.67 seconds each can be
recorded.
• Acquisition time: This setting determines how much time before the triggering point is included in the
record. The recording time must be at least 0.2 s to record the pre-fault and 0.3 s for the post-fault
history.

Signals

Bay Units
All binary signals (input, output or internal signal) can be recorded. For this purpose, they must be
configured for recording and identified by their signal labels.
Up to 32 binary signals per bay can be selected for recording. Of these, up to 12 can be configured to
trigger the start of 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
Once recording has been started, the complete recording period that has been set is recorded.
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
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 disconnectors 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 disconnector.
