12 System data

The various control functions and methods according to the selected
supplemented by control and special functions. For monitoring the application, 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 effected at a constant pressure H (change of conveying flow Q, pressure H remains
constant). The transition to partial load operation mode B2 can be effected 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
440 of the technology controller.
