Fig e shows the improved, with the mandatory nature of the program secondary circuit schematic diagram. Firstly deficiencies of conventional secondary circuit, the circuit in Figure b form, it seems perfectly reasonable, it works we are all familiar. However, many operators, the quality varies, assuming that the operator of a small mistake by running the button to start the device. B from FIG principle, the press QAz run button, so the device is based on the procedure after the first press starts running through QA, start button, but more than misuse, can make the run contactor C: pull into the work state, becoming a direct start, this time starting current cause great damage to the equipment. For this reason we designed the circuit shown in Figure c, before it can completely prevent the occurrence of accidents.
