Figure 158: Characteristic of load encroachment function
The influence of load encroachment function on the operation characteristic is
dependent on the chosen operation mode of the FRPSPDIS function. When output
signal STCNDZis selected, the characteristic for the FRPSPDIS (and also zone
measurement depending on settings) can be reduced by the load encroachment
characteristic (as shown in figure
159).
