The protection relay supports four 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 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.
