13-3. DRIVING SYSTEM CIRCUIT

   

Description

Controls all driving components (Valve, Drain motor, etc) by turning on/off the TRIAC of each system.

Operation

- MICOM outputs a high signal of 5V on pins #1~7 of IC3.
- Then pins #10~16 of IC3 will be grounded (0V).
- Once pins #10~16 of IC3 are grounded, TRIAC 1, 2, 3, 4, 5 and 6 turn on due to the electric potential difference to the 
  12V.
- Power is applied to the electric components (MOTOR, VALVE, and DRAIN MOTOR) connected to CN9 and the operation 
  starts.
- If PWM signal is applied to the BASE of TR3, BZ1 starts to operate due to the electric potential difference between the 
  12V and DGND. The operating sound of BZ1 changes according as the DUTY of PWM changes.
