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.
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.
