Functions
2.1 General
2.1.4.1
Functional Description
The data of a fault event can be read out via the device interface and evaluated with the help of the SIGRA 4
graphic analysis software. SIGRA 4 graphically represents the data recorded during the fault event and also
calculates additional information from the measured values. Currents and voltages can be presented either as
primary or as secondary values. Signals are additionally recorded as binary tracks (marks) e.g. "pickup", "trip".
If port B of the device has been configured correspondingly, the fault record data can be imported by a central
controller via this interface and evaluated. Currents and voltages are prepared for a graphic representation.
Signals are additionally recorded as binary tracks (marks) e.g. "pickup", "trip".
The retrieval of the fault data by the central controller takes place automatically either after each protection
pickup or after a tipping.

The signals used for the binary tracks can be allocated in DIGSI.

Setting Notes
Specifications
The actual storage time encompasses the pre-fault time PRE. TRIG. TIME (address 411) ahead of the refer-
ence instant, the normal recording time and the post-fault time POST REC. TIME (address 412) after the
storage criterion has reset. The maximum storage time for each fault recording (MAX. LENGTH) is entered in
address 410. Recording per fault must not exceed 5 seconds. A total of 8 records can be saved. However, the
total length of time of all fault records in the buffer must not exceed 25 seconds.
2.1.4.3
Settings
Addresses which have an appended "A" can only be changed with DIGSI, under "Additional Settings".
