13-3. DRIVING SYSTEM CIRCUIT
Function
- Controls each driving system (VALVE, DOOR S/W, DRAIN-MOTOR) by turning RELAY or TRIAC on/off.
Description
- MICOM outputs a high signal of 5V from pin # 1 - 7
- Then, pin # 10 to 16 of IC6 and IC8 are electrically grounded (0V).
- When pin # 10 to 16 are grounded, this creates an electric potential difference from the 12V that turns on RELAY 5,6,7
and TRIAC2,3,4,5.
- The operating parts (VALVE, DRAIN-MOTOR, DOOR S/W) connected to CN9 turn on if they are supplied with power.
