Change Group

operation the user can locally switch between setting groups using the operator panel,
binary inputs (if so configured), the operator and service interface per PC, or via the
system interface.
A setting group includes the setting values for all functions that have been selected as
Enabled during configuration (see Section 2.2). In the 7UM61 device, two indepen-
dent setting groups (A and B) are available. Whereas setting values may vary, the se-
lected functions of each setting group remain the same.
Where different settings are required for operational reasons, e.g. in pumped storage
power stations with a machine operating alternately as a generator and a motor, these
settings are made in the setting groups and stored in the device. Depending on the
operating mode, the applicable setting group is activated, usually via a binary input.
If multiple setting groups are not required, Group A is the default selection. The rest of
this section is not relevant.

Setting Notes

General If the changeover option is desired, on function extent configuration group changeover
must be set to Grp Chge OPTION = Enabled (address 103). When setting the func-
tion parameters, you configure first setting group A, then setting group B. How to
proceed and how to copy or reset settings groups are described in the SIPROTEC
System Description /1/.
How to switch between setting groups externally using binary inputs is described in the
Mounting and Commissioning section.
