The actual storage time begins at the pre-fault time PRE. TRIG. TIME (address 404) ahead of the reference
instant, and ends at the post-fault time POST REC. TIME (address 405) after the storage criterion has reset.
The maximum recording duration for each fault (MAX. LENGTH) is entered in address 403. The setting
depends on the criterion for storage, the delay time of the protective functions and the desired number of stored
fault events. The largest value here is 5 s for fault recording of instantaneous values, 80 s for recording of rms
values (see also address 104). A total of 8 records can be saved in this time.
Note: If RMS values are stored, the times stated for parameters 403 to 406 will be 16 times longer.
An oscillographic record can be triggered by a change in status of a binary input, or through the operating in-
terface via PC. The trigger is dynamic. The length of a record for these special triggers is set in address 406
BinIn CAPT.TIME (upper bound is MAX. LENGTH, address 403). Pre-fault and post-fault times will be added.
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 403, whichever is shorter.
