Configuration of Signals to Be Recorded
All analog inputs of the device that have been configured (currents and voltages) are recorded as sampled
channels.
Function-specific binary signals (for example, pickup and trip signals) and measured value channels can be
configured individually for recording in the DIGSI information-routing matrix. For this purpose, a separate
Recorder column is available.
You can rename the signals in the DIGSI Information routing matrix. You can change the sequence of the
binary signals and measured-value channels to be recorded in DIGSI under Signal order. You can find more
detailed information on this in the DIGSI 5 Online Help from version V07.50 and higher (Order number:
C53000-D5040-C001-D).
The operational measured values and the measured values of the fundamental components and symmetrical
components (see the Device Manual, chapters
9.3 Operational Measured Values and 9.4 Fundamental and
Symmetrical Components ) are calculated every 9 cycles (at 50 Hz, this is every 180 ms). However, this can
mean that the data are not synchronized with the sampled values of the analog channels. The recording of
these measured values can be used to analyze the slowly changing processes.
Numbering and Time Stamping
All fault recordings saved are automatically numbered in ascending order and assigned a real-time stamp for
the start time. The fault recording logs the fault with a relative time. The reference-time point is the start of
the recording. Every fault recording has a corresponding fault log with the same number. This ensures that the
fault recording can be uniquely assigned to the event log.
Fault Memory
The device manages its available fault memory dynamically, so that the maximum recording capacity is always
available. When exceeding the limits of the fault memory, the oldest recordings are automatically overwritten.
This means that the most recent recordings are always available. The sampling rate, type, and number of
measured value trends to be recorded are the crucial variables when it comes to restricting the length and
number of recordings possible. Parallel to the sampled tracks, up to 50 tracks with function-specific measured
values and up to 200 binary tracks can be recorded. The following table provides an overview of the maximum
storage capacities, in seconds, for different connection variations of the protection devices.

Input and Output Signals
The Fault recorder function provides several input signals that allow the precise starting, deleting of record-
ings. The output signals provide information about the function status.
In the following table, you can find input signals of the Fault recorder function:
Name Type Description
Control: Start recording SPC Start recording via the function key
Control: Reset memory SPC Delete all recording via the function key. The
error numbers are reset.
