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
Fig. 5.1.4.7.-1 shows an example of manual checksum calculation.
