Image 7.57: “Hydraulic signal scaling, pressure” screen
P 2845 - HYD_Input_Val will show the unscaled pressure reference and actual
values for the pressure control.
Further processing and scaling is carried out in P 2846 - HYD_Input_Adapt. A
scaling factor, an offset, and a signal limit (min and max) can be set.
