As in previous firmware versions, F650 elements incorporate a flexible grouping capability for elements grouped in
protection elements section. However, two different working modes have been implemented for firmware version 7.5X
and above
This means that protection elements can be used in either one of the following modes:
5.4.1.2.1 Single setting group
In this operation mode, all protection elements under one particular Setting Group can be activated and operated
simultaneously. When the Setting Group Function is disabled at Setpoint > Control Elements > Setting Group, protection
elements of the group selected as the Active Group become available.
