2.1.4.2 Setting Notes
Specifications
Fault recording (waveform capture) will only take place if address 104 OSC. FAULT REC. is set to Enabled.
Other settings pertaining to fault recording (waveform capture) are found in the Osc. Fault Rec. OSC.
FAULT REC. submenu of the SETTINGS menu. Waveform capture makes a distinction between the trigger
instant for an oscillographic record and the criterion to save the record (address 401 WAVEFORMTRIGGER).
Normally, the trigger is the pickup of a protection element, i.e. the time 0 is defined as the instant the first pro-
tection function picks up. 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.
A fault event starts with the pickup by any protection function and ends with the dropout of the last pickup of a
protection function.
The actual storage time encompasses the pre-fault time PRE. TRIG. TIME (address 404) ahead of the ref-
erence instant, the normal recording time and the post-fault time POST REC. TIME (address 405) after the
storage criterion has reset. The maximum recording duration to each fault (MAX. LENGTH) is entered in
address 403. 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 18 seconds.
An oscillographic record can be triggered by a status change of a binary input, or from a PC via the operator
interface. Storage is then triggered dynamically. The length of the fault recording is set in address 406 BinIn
CAPT.TIME (but not longer than MAX. LENGTH, address 403). Pre-fault and post-fault times will add to this.
If the binary input time is set to ∞, the length of the record equals the time that the binary input is activated
(static), but not longer than the MAX. LENGTH (address 403).
