11 System Data

The various control functions and methods according to the selected
30 are supplemented by control and special functions. For monitoring the applica-
tion, process parameters are calculated from electrical control parameters.

Line mains or channel characteristic:
Point A in the figure describes the rating point of a pump. The transition to partial
load operation mode B1 can be affected at a constant pressure H (change of convey-
ing flow Q, pressure H remains constant). The transition to partial load operation
mode B2 can be affected according to the bad point method (change of pressure H
and conveying flow Q). Both methods can be realized with the integrated technology
controller in configurations 111, 211, 411 and 611. The actual values displayed are
calculated according to the bad point method independently of the selected
tion mode
