using discharge gates. The VFD is located in the plant main electrical service panel. The speed of the conveyor is controlled by the batch control using the faster and slower function. The conveyor will operate in a range from 1/3 of full speed to full speed. Three outputs are required from the batch control to operate this batcher.

Interlock - an overview | ScienceDirect Topics
Another example of a simple interlock system is illustrated in Figures 34.15 and 34.16. Figure 34.15 shows a plant consisting of a water-cooled reactor in which a batch reaction is carried out. The reactor is charged with chemical A, and chemical B is then fed in gradually from a weigh tank as the reaction proceeds.
