Reset LED Group
The Reset LED group function block allows you to reset only the stored LEDs of the functions contained in the
respective function group, while stored LEDs activated from functions in other function groups remain active.
For more information refer to chapter 3.1.10 Resetting Stored Indications of the Function Group .
Operational, Fundamental, Symmetrical Components Measurements
The operational fundamental, symmetrical components and functional measurements are always available in
the Capacitor bank function group and cannot be deleted.
