Work of the circuit The circuit consists of power circuit, timing circuit, sound indicating circuit, magnetism pulse controlling circuit and heating controlling circuit. (It is showed in picture 9-15.) Turn on power switch S1. The 220V AC voltage is adjusted and produces +15V voltage. It separates in to two parts. One is supplied to sound indicating circuit and magnetism pulse controlling circuit. While the other one is changed into 9V voltage and IC2 and KN. The regular time is 60min. turn on the power and EH makes sounds. When the regular time is over, EH stops working and HA makes sound. When EH is working, the temperature increases as well as the value of RT. When it reaches a certain degree, EH stops working. So the temperature decreases and EH starts to work again. This process is repeated until the regular time is over.
