Where transfer to a central device is possible, the request for data transfer can be ex-
ecuted automatically. It can be selected to take place after each protection pickup or
after a trip only.
2.22.8.2 Setting Notes
Other settings pertaining to fault recording (waveform capture) are found in the
submenu Oscillographic Fault Records of the Settings menu. Waveform capture
makes a distinction between the trigger instant for an oscillographic record and the cri-
terion to save the record (address 901 WAVEFORMTRIGGER). Normally the trigger is
the pickup of a protective element, i.e. the time 0 is defined as the instant picked up
by the first protection function. The criterion for saving may be both the device pickup
(Save w. Pickup) or the device trip (Save w. TRIP). A trip command issued by
the device can also be used as trigger instant (Start w. TRIP); in this case it is also
the saving criterion.
The actual storage time begins at the pre-fault time PRE. TRIG. TIME (address 904)
ahead of the reference instant, and ends at the post-fault timePOST REC. TIME (ad-
dress 905) after the storage criterion has reset. The maximum recording duration to
each fault (MAX. LENGTH) is entered in address 903. Recording to each fault may
take max. 5 seconds. A total of 8 records can be saved. However the total length of
time of all fault records in the buffer may not exceed 5 seconds.
An oscillographic record can be triggered and saved by a change in status of a binary
input or via the operating interface connected to a PC. Storage is then triggered dy-
namically. The length of a record for these special triggers is set in address 906
BinIn CAPT.TIME (upper bound is MAX. LENGTH, address 903). Pre-trigger and
post-dropout times are included. If the binary input time is set to ∞, then the length of
the record equals the time that the binary input is activated (static), or the MAX.
LENGTH setting in address 903, whichever is shorter.
