Work of the circuit The circuit consists of Power supply circuit, pulse generator, control implementation delay circuit and control circuit. ( It is showed in picture 8-91.) Power supply circuit consists of buck capacitor Cl, discharge resistor R7, voltage regulator diode VS, the rectifier diode VDl and filter capacitor C2. Pulse generator consists of time-base integrated circuit ICl, resistors Rl and R2, potentiometers RP and capacitors C3. Control implementation delay circuit consists of decimal counting / pulse distributor circuit IC2, resistors R3 and R4, diode VD2-VD11, switch S1-S12. Control circuit consists of transistor V, resistors R5 and R6, thyristor VT and AC contactor KM.
