Siemens SIPROTEC 4 7SD80 User Manual

Functional 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 7SD80 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.
Setting Notes
General
If setting group change option is not required, Group A is the default selection. Then, the rest of this section is
not applicable.
If the changeover option is desired, group changeover must be set to Grp Chge OPTION = Enabled
(address 103) when the function extent is configured. For the setting of the function parameters, each of the
required setting groups A to D (a maximum of 4) must be configured in sequence. The SIPROTEC 4 System
Description gives further information on how to copy setting groups or reset them to their status at delivery
and also how to change from one setting group to another.
Section 3.1 Mounting and Connections of this manual tells you how to change between several setting groups
externally via binary inputs.
