Functionality

3.7.2.1 Setting group control
The protection relay supports six setting groups. Each setting group contains
parameters categorized as group settings inside application functions. The
customer can change the active setting group at run time.
The active setting group can be changed by a parameter or via binary inputs
depending on the mode selected with the Configuration > Setting Group > SG
operation mode setting.
The default value of all inputs is FALSE, which makes it possible to use only the
required number of inputs and leave the rest disconnected. The setting group
selection is not dependent on the SG_x_ACT outputs.
