Example 1
As shown in figure 1 of the drawings, in which,
in this embodiment, the U-phase of the main fan frequency converter passes through the current sensing switch. The normally open output switch point and the intermediate relay KA2 are connected in series with a direct current 24V power supply, and the parameter action current is adjusted by 5A. When the fan operates, the current is larger than 5A, the auxiliary point is closed, and the water pump starts to operate; when the stopping current of the fan is zero and is less than 5A, the auxiliary point is disconnected, the water pump stops running in a linkage mode, and linkage control is achieved.
