Sequence control switch in the Magical
Bucket powder grinder is a grinder output mix of a cage; stop the grinder when the order is a cage of a powder mill output mixing bucket. According to the traditional control methods: one by one start and stop according to process requirements, and second, automatic control circuit with interlock to ensure correct operation. The former is prone to misuse, the latter line complex,[link widoczny dla zalogowanych], difficult to achieve. In accordance with a certain type of structural characteristics of switch contacts (see Figure 2),[link widoczny dla zalogowanych], design a control circuit shown in Figure 3, the advantages are as follows: l absolute assurance process requirements of the start and stop order will not misuse, because of the conversion operating characteristics of the switch just after the start with the first stop, first stop after the start the principle of agreement. 2 to Figure 1, the conventional control method to use 6 buttons, but as long as a switch,[link widoczny dla zalogowanych], this would both reduce costs,[link widoczny dla zalogowanych], save box space, easy to operate, while allowing the control circuit is particularly simple, reduced wiring, fault rate decreased maintenance easier. If the motor also need to control more of the methods used switch to the more obvious advantages. Thus,[link widoczny dla zalogowanych], we can not find, if a control theory based on the contact map out exactly the picture with a wide range of contacts diagram of a switch corresponding to switch to switch control, you can get a multiplier effect.
