$ :$9()250&$3785(). Normally the reference instant is the occurrence of de-
vice fault detection, i.e. the fault detection of any protection function is allocated with
the time stamp 0. The fault detection can also be the storage criterion (6DYHZ
3LFNXS) or the device trip command (6DYHZ75,3) can be the storage criterion.
The device trip command can also be used as reference time (6WDUWZ75,3); in
this case it is also the storage criterion.
A fault event starts with the fault detection of any protection function and ends with the
reset of the last fault detection. Usually this is also the extent of a fault recording (ad-
dress $ 6&23(2) :$9()250'$7$ = )DXOWHYHQW). If automatic reclosure is
implemented, the entire system disturbance — possibly with several reclose
attempts — up to the ultimate fault clearance can be stored (address $ 6&23(2)
:$9()250'$7$ = 3RZHU6\VWHPIDXOW). This facilitates the representation of the
entire system fault history, but also consumes storage capacity during the auto-reclos-
ure dead time(s).
The actual storage time encompasses the pre-fault time 35(75,*7,0( (address
) ahead of the reference instant, the normal recording time and the post-fault time
32675(&7,0( (address ) after the storage criterion has reset. The maximum
permissible storage period per fault recording 0$;/(1*7+ is set in address . A
maximum recording time of 5 s is available per fault recording. In total up to 8 fault
records with a total recording time of max. 15 s can be stored.
The fault recording can also be triggered via a binary input, via the keypad on the front
of the device or with a PC via the operation or service interface. The storage is then
dynamically triggered. The length of the fault recording is set in address  %LQ,Q
&$377,0( (maximum length however is 0$;/(1*7+, address . The pre-
and post-fault times are additive. If the time for the binary input is set to ∞, the duration
of the storage is as long as the binary input is initiated (static), the maximum length
however still is 0$;/(1*7+ (address ).
