5.1 Configuration of Functions
General The 7SJ62 relay contains a series of selectable protection functions as well as many
other functions, based on the options purchased. The first step in configuring the relay
is to determine which functions are required.
Example
for the configuration of functional scope:
A protected system consists of overhead and underground feeders. Since automatic
reclosing is only needed for the overhead feeders, the automatic reclosing function is
not configured or “Disabled” for the relays protecting the underground feeders.
The available functions must be configured as HQDEOHG RU GLVDEOHG. For individual
functions, the choice between several alternatives may be presented, as described
below.
Functions configured as GLVDEOHG are not processed by the 7SJ62. There are no
messages, and corresponding settings (functions, limit values) are not displayed dur-
ing detailed settings.
Determination of
Functional Scope
Configuration settings must be entered using a PC and the software program

manual, order number E50417-H1176-C097.
Entry of password No. 7 (for setting modification) is required to modify configuration
settings (see Section 4). Without the password, the settings may be read, but may not
be modified and transmitted to the device.
The functional scope with the available alternatives is set in the 'HYLFH&RQILJX
UDWLRQ dialog 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 menu closes automatically upon selection of
an item.
Note:
Available functions and default settings are depending on the ordering code of the re-
lay (see table 6-1 and ordering code in the appendix for details).
