a)
The FLA secondary scaling factor has only one setting and thus switching between setting groups does not apply.
b)
The setting step is 0.5.
Switchgroups and parameter masks
The settings can be altered and the functions of the relay selected in the SG_ selector
switchgroups. The switchgroups are software based and thus not physical switches
to be found in the hardware of the relay.
A checksum is used for verifying that the switches have been properly set. The
figure below shows an example of manual checksum calculation.
