In order to realize the automation of yarn dyeing, a textile factory uses electronic circuits to control the forward, reverse or intermediate pause of the yarn dyeing machine. Figures a and b are the automatic control circuits of
yarn dyeing machines . VT1 and VT2 form a self-cleaning multivibrator circuit, VT3 and VT4 form a monostable circuit , and Kl and
K2 are 121-type high-sensitivity relays (internal resistance is 2k0). , KM1 and KM2 are AC contactors , their working principles are as follows.
