4.11.3 Functionality
The multipurpose protection function MAPGAPC is used as a general protection
with many possible application areas as it has flexible measuring and setting
facilities. The function can be used as an under- or overprotection with a settable
absolute hysteresis limit. The function operates with the definite time (DT)
characteristics.
The function contains a blocking functionality. It is possible to block function
outputs, the definite timer or the function itself, if desired.
4.11.4 Operation principle
The function can be enabled and disabled with the
Operation setting. The
corresponding parameter values are "On" and "Off".
The operation of MAPGAPC can be described using a module diagram. All the
modules in the diagram are explained in the next sections.
