Start recording by an external binary signal, for
example, by the trip command of an external
protection device. The set pre and post-trigger
time are taken into account.
Control: >Manual start
SPS
Start a recording of fixed duration (parameter
Manual record time
) by way of an

Recommended setting value
(_:2761:130) Fault recording
=
with pickup
With the
Fault recording
parameter, you define the time interval at which faults are recorded. The total
record duration is defined as the duration of the fault plus the total of the parameters
Pre-trigger time
,
Post-trigger time
and is limited by the maximum record duration.
Parameter Value
Description
with pickup
The fault recording time is determined by the total number of all protection
pickups. The resulting pickup signals of all function groups are taken into
account.
Note: When the post-trigger time has expired, the indications of an auto-
matic reclosing function are not recorded. Evolving faults after expiry of the
post-trigger time can result in the opening of a new fault with its own
recording.
user-defined
The fault recording time is defined user-specific.
Note: You must specify all signals for individual definition of the fault
recording time in the DIGSI 5 information-routing matrix. In the information
routing matrix in the Fault record column, the fault recording has for this
purpose a separate column Trigger. The record duration is calculated from
the logical OR operation of all initiated, configured signals.
Parameter: Storage
•
Recommended setting value
(_:2761:131) Storage
=
always
With the
Storage
parameter, you define the storage criterion for a fault recording that has already started.
Parameter Value
Description
always
Each fault recording that has been started is saved.
