11. REFERENCE INFORMATION 11-1.
11-2. TERMINOLOGY 1) ASSY-MAIN PCB (Imbalance Sensor) → To prevent the laundry from gathering on one side of the tube causing noise and vibration, the washing machine uses an imbalance detection device that evenly disentangles the laundry before the hydrating cycle starts. 2) DOOR-LOCK S/W → Prevents the door from being opened while a cycle is in progress. For safety purposes, it keeps the door locked even in pause mode or after the washing cycle unless the water level frequency is greater than 24.
9) PRE-WASH → The machine does a preliminary wash of about 10 minutes prior to the main wash. This is particularly effective for cleaning badly stained laundry. 10) WEIGHT SENSOR → The tube automatically rotates when no water is supplied to detect the laundry weight so that the proper wash time can be determined.

12. CIRCUIT DESCRIPTION 12-1.
12-2. 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. - The secondary 12V depends on the ZD1 value. - The 12V for the LVT1 secondary source is transformed to DC 5V through IC4.
12-3. 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). - 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.
12-4. Motor Circuit ▶ Function Supplies power to the motor and turns it CW/CCW (Right / Reverse direction). ▶ Description - The operation of TRIAC1 is the same as that of the driving system. - If the electric potential of R48 is grounded (0V), TRIAC1 turns on. - CN1 detects if the door is locked or unlocked. If unlocked, it does not apply power to the motor even if TRIAC1 turns on.
12-5. 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. - The DHSEH sensor is connected to CN7 pin 5 and CN6 pins 3,4. - The resistance of the temp. sensor changes according to the ambient temperature.
12-6. Motor TACHO Input System ▶ Function Detects the current RPM of the motor and controls the output. ▶ Description - The motor TACHO sensor is connected to CN10 B-pin. - According to the current RPM of the motor, a square wave is applied to pin 8. - The square wave that is input to TR2 BASE turns the motor on if high (5V), and turns it off if low (0V). And this operation will be inverted to TACHO NET for a clear wave with no noise. - The signal is applied to MICOM pin 13.
12-7. 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. Then, SINAL_A and SIGNAL_B output a high signal of 5V. - Both SIGNAL_A and SIGNAL_B repeat this for 15 seconds outputting a high signal of 5V.
