The settings associated with the various device functions can be modified using the
operating or service interface in DIGSI on a PC. Some parameters may also be
changed using the controls on the front panel of the device. The detailed procedure is
described in the SIPROTEC 4 System /1/.
The 7SJ62/63/64 relay contains protection functions as well as many other functions.
The hardware and firmware is designed for this scope of functions. Additionally, the
control functions can be matched to the system requirements. Individual functions can
be enabled or disabled during the configuration procedure. The interaction of functions
may also be modified.
Example for the configuration of functional scope:
A protected system consists of overhead lines and underground cables. Since auto-
matic reclosing is only needed for the overhead lines, the automatic reclosing function
is not configured or "Disabled" for the relays protecting the underground cables.
The available protection and additional functions must be configured as Enabled or
Disabled. For individual functions, a choice between several alternatives may be
presented, as described below.
Functions configured as Disabled are not processed by the 7SJ62/63/64. There are
no messages, and corresponding settings (functions, limit values) are not queried
during configuration.
Note
Available functions and default settings depend on the ordering code of the relay (see
A.1 for details).
Configuration settings can be entered using a PC and the software program DIGSI
and transferred via the front serial port or the rear service interface. The operation via
DIGSI is explained in the SIPROTEC 4 System Description.
For changing configuration parameters in the device, password no.7 is required (for
parameter set). Without the password, the settings may be read, but may not be mod-
ified and transmitted to the device.
The functional scope with the available options is set in the Functional Scope dialog
box to match plant requirements.
