MICOM FUNCTION & PCB CIRCUIT EXPLANATION
2. OSCILLATION CIRCUIT
CIRCUIT for occurring CLOCK which motivates the internal local element of IC1 to transmit and receive an information and
BASIC TIME for calculating time. Use a proper form for OSC 1. Because in case that SPECIFICATION is changed, the calculated time in IC1
is changed or IC1 isn't able to operate.
3. RESET CIRCUIT
All the internal parts of MICOM(IC1) return to the initial condition when the early power ON or apply power again in MICOM after
temporary power failure. As a result, all the functions operate according to the early condition. At the early period of power ON the "LOW"
voltage is applied in the RESET terminal of MICOM for the fixed time. The RESET terminal is 5V during the general operation.
