  • Page 78 13-2. AC Input & Power Circuit ▶ Function Generates a required DC power of 12V or 5V in case of supplied or disconnected AC power. ▶ Description - When AC 220V is applied to CN3, D17 D20 transforms it to DC 300V. - DC 300V is generated for the LVT1 secondary source by IC3 and PC1 turning on/off.
  • Page 79 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 of IC7 and IC9. 　 - Then, pin # 10 to 16 of IC7 and IC9 are electrically grounded (0V).
  • Page 80 13-4. Sensor Detection Circuit ▶ Function Detects signals from the sensor and controls the current system. ▶ Description - The water level sensor is connected to pin 4 of CN7. - The frequency of the level sensor changes according to the water amount in the tub. - Then, the frequency is input to MICOM pin 48 for detecting the water amount.
  • Page 81 13-5. Silver Nano System ▶ Function Applies the electric current to the silver plate during the water supply and uses the silver water to perform the bacteria-free or sterilization processes. ▶ Description - Selects the silver nano feature to operate the system. - Supplies water to the two silver plates AG_B and AG_A.
