Purpose of the Setting Groups

Up to four different setting groups can be created for establishing the device's function settings. During opera-
tion, the user can locally switch between setting groups using the operator panel, binary inputs (if so config-
ured), the operator and service interface from 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 during configuration as
Enabled or an other active option. In 7VK61devices, four independent setting groups (A to D) are available.
Whereas setting values and options may vary, the selected scope of functions is the same for all groups.
