Siemens SIPROTEC 4 7SJ61 User Manual

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 storage duration of each fault record (MAX. LENGTH) is entered at address 403. Recording per
fault must not exceed 5 seconds. At least 8 records can be saved altogether with a minimum total time of
20 s .
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).

Settings Groups
Up to four different setting groups can be created for establishing the device's function settings.
Applications
•
Setting groups enable the user to save the corresponding settings for each application so that they can
be quickly called up when required. All setting groups are stored in the device. Only one setting group
may be active at a time.
Description
Changing Setting Groups
During operation the user can switch back and forth setting groups locally, via the operator panel, binary
inputs (if so configured), the service interface using a personal computer, or via the system interface. For
reasons of safety it is not possible to change between setting groups during a power system fault.
A setting group includes the setting values for all functions that have been selected as Enabled during
configuration (see Section 2.1.1.2 Setting Notes). In 7SJ61 relays, four independent setting groups (A to D)
are available. While setting values may vary, the selected functions of each setting group remain the same.
