Settings Groups

Up to four different setting groups can be created for establishing the device's function settings.

2.1.5.1 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 con-
figuration (see Section 2.1.1.2). In 7SK80 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.

2.1.5.2 Setting Notes

General
If you do not need the setting group change option, use the default group A. The rest of this paragraph is then
not relevant.
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.
Subsection 3.1 of this manual tells you how to change between several setting groups externally via binary
inputs.
