is also the extent of a fault recording (address :$9()250'$7$ = )DXOW
HYHQW). If automatic reclosure is implemented, the entire system disturbance — pos-
sibly with several reclose attempts — up to the ultimate fault clearance can be stored
(address :$9()250'$7$ = 3RZ6\V)OW). This facilitates the representation
of the entire system fault history, but also consumes storage capacity during the auto-
reclosure dead time(s). This setting is only possible via DIGSI
®
at Additional Set-
tings.
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
32675(&7,0( (address ) after the storage criterion has reset. The maximum
length of time of a fault record 0$;/(1*7+ is entered in Address .
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
&$377,0( (maximum length however is 0$;/(1*7+, address ). Pre-fault and
post-fault times will be included. If the binary input time is set for ∞, then the length of
the record equals the time that the binary input is activated (static), or the 0$;
/(1*7+ setting in address , whichever is shorter.
2.1.6.3 Settings
Addresses which have an appended "A" can only be changed with DIGSI, under Ad-
ditional Settings.
