Figure 138: Difference in operating characteristic depending on operation mode when load
encroachment is activated
When FRPSPDIS (21) is set to operate together with a distance measuring zone the resultant
operate characteristic could look like in figure 139. The figure shows a distance measuring zone
operating in forward direction. Thus, the operating area of the zone together with the load
encroachment is highlighted in black.
