Configuration of Functions

General
Determination of
Functional Scope
5-2
The 7SA6 relay contains a series of protective and additional functions. The scope of
hardware and firmware is matched to these functions. Furthermore, commands
(control actions) can be suited to individual needs of the protected object. In addition,
individual functions may be enabled or disabled during configuration, or interaction
between functions may be adjusted.
In the following, an example for the configuration of the functions:
A substation has overhead line and transformer feeders. Fault location must only be
carried out on the overhead lines. This function therefore is disabled for devices on
transformer feeders.
The available functions must be configured as HQDEOHG or GLVDEOHG. For individual
functions, the choice between several alternatives may be presented, as described
below.
Functions configured as GLVDEOHG are not processed by the 7SA6. There are no
messages, and corresponding settings (functions, limit values) are not displayed
during detailed settings.
Note:
Available functions and default settings depend on the ordering code of the relay (see
ordering code in the appendix for details).
Configuration settings can be entered using a PC and the software program DIGSI
and transferred via the operating interface on the device front, or via the rear serial
service interface. Operation via DIGSI

Entry of password No. 7 (for setting modification, default 000000) is required to modify
configuration settings (see Chapter 4, last paragraph). Without the password, the
settings may be read, but cannot be modified and transmitted to the device.
The functional scope with the available options is set in the 'HYLFH &RQILJXUDWLRQ
dialogue box (see Figure 5-1) to match equipment requirements. To change a
function, click on the corresponding line under 6FRSH, and select the desired option
in the list which appears. The drop-down list closes automatically upon selection of an
item.
