3-3. MAIN FUNCTION

1)Auto power S/W off function

●After power on, the auto power S/W off function automatically switches power off for you if you do not press selection button for 10 minutes.

●After selecting the function, the auto power S/W off function automatically switches power off for you if you do not press start/pause button for 10 minutes.

●until 5 minutes past, After fi nishing the last function, the auto power S/W off function automatically switches power off for you if you do not re-select the course button or manual button.

2)Door open function

● Door just can be opened at water level 24.80 KHz over, water temperature 55 below, motor off, if power is off door is not opened (only auto-door model).

●If door is open during the operating, all operating is halted, and door error message will be displayed (2-digit panel displays “dE” 4-digit panel displays “door”) and error melody will coming out .

●Door open error can be cleared by closing the door. the operating keeps going on.

3)Rinse hold function

●If rinse hold function selected, the operating is fi nished , the machine do not drain the water after last rinse.

4)No spin function

●If no spin function selected, the operating is fi nished after last rinse.

5)Drain function

●Drain function is over, after pumping out the water for 2 minutes , without motor rotating.

6)Pre-washing function

●Pre-washing function can be selected ,when you choice the following mode; cotton, coloreds, syn. thetics, delicates, baby cotton, baby coloreds, baby delicates, baby stains.

●Water level/reverse time is the same with the selected course.

●Pre-washing takes about 16 minutes.

7)Power-out compensation function

●If power is out on selected process, the process before power out is stored to EEPROM, once power is

back the process before power out continues.

● When power is back, washing process starts from the process at the point of the power out, rinse/drain process starts from the initial process.

8)Fuzzy washing function (weight-sensing)

●After fi nishing initial water supply, when the fall of the water level needs supplementary water supply, Sensing function perceives the weight with the supplementary water supply numbers and starts to work. Under the course of Cotton, or Coloureds, if the supplementary water supply numbers become over 2 times the function is going at default condition ( high water level ), if 1 time that is going at middle level, if 0 below low water level, heating hours and rinse hours depend on the above data.

ECO PRE mode is selected, the process going on at default condition.

		Washing hours		Rinse water level
	Cotton		Coloureds
High	Default		Default	Default
Middle	Default-20 min		Default-10min	23.80KHZ
Low	Default-30 min		Default-15min	24.10KHZ

After sensing weight, above hours is decreased from above default hours

9) Bubble - detecting function

At the each condition of washing&dehydrating , rinse&dehydrating , hydrating, bubble -detecting function

works, this function works 5times normally, if the function detects bubbles at 6 times , the bubble-detecting function stops and go on to the next process.

●The bubble-detecting function during washing & dehydrating to rinse & dehydrating

after 2 times instant dehydrating and before main dehydrating, if the water level is under 24.50KHZ, Bubble

→Detecting function thinks there are bubbles and add the bubbles-removing rinse, needing hours are above hours and 8 Min 40 sec.

→The bubble-detecting function during single hydrating process

after 2 times instant dehydrating and before main dehydrating , if the water level is 24.50KHZ below or during main dehydrating, water level data is 24.50KHZ below Bubble-detecting function thinks there are bubbles and add the bubbles-removing rinse 1 times, needing hours are above hours and 5 min 50 sec.

10)Unbalance detecting & laundry balance positioning system

Just before the hydrating process and just after reversal rotation for balancing laundry position, this function is carried out

The initial 6 sec is the period of reversal rotation for balancing laundry position , Drum rotates 50rpm for initial 6 sec

Next 12 sec, the rotation increases the speed from 50 rpm to 95 rpm slowly

During the next 8 sec, drum rotates at the speed of 95 rpm, the sensor decides the degree of laundry unbalance with TACHO data which is attached to motor

If the degree of unbalanced laundry is over 6 times to default value, laundry balancing system carryies out feed back process 3 times.

11) R.P.M control

The rotating motor enables the magnetics( i.e generator) to generate magnetic fl ux in proportion to r.p.m, magnetic fl ux induced by coil sensor in the opposite side produces the wave like the fi gure below to dΦ/dt and via rectangular wave generating circuit, the waves reaches MICOM and micom controls r.p.m with the pulse, count and cycle inputted by program.

4. ALIGNMENT AND ADJUSTMENTS

4-1. GENERAL ERROR FUNCTION

1.An occurrence of an Error will make a sound of error melody for 5sec and continuously show one of the Error Displays from the following errors. (But, Fault Check Led will fl ash for 0.5sec.)

2.All of the steering parts will be off at that time until that error was released.

3.Water Supply Error

-If there is no higher change in water frequency than 100Hz for 2 minutes during the initial time of water supply and if water level doesn’t reach the preset level in 10 minutes, this error will occur.

This error will be released using Start/Pause button, which performs the initial condition of operation.

-Display : “4E”

4.Water Drain Error

-If water level frequency is still lower than the reset level frequency (25.20kHz) in 10 minutes after starting of water drain, this error will occur.

This error will be released using Start/Pause button, which performs the initial condition of operation.

-Display : “5E”

5.Over Flow Error

-If an abnormal water level frequency is sensed (for occurrence of Over Flow :21.00kHz), Auto Power Off may release this error and continuously progress water drain until the frequency reached 25.00kHz.

-If Over Flow is also sensed even after the following check of water level frequency indicating that error, it functions to progress water drain.

-Display : “OE”

6.Door Open Error

-This error will be released by closing Door.

-Display : “door”

7.Unbalance Error

-This error will be released by pressing start/pause S/W.

-DISPLAY : “ UE”

8.Water Heater Error

-This error will be released by turning off Power S/W.

-Display : “HE1”(Over Heat),

-Display : “HE2”, indicating no operation of HE.

9.Pressure S/W (Single Part Trouble) Error

Frequency signals(kHz) generated by water level S/W

Water Level	Low	High
Abnormal Frequency	30.00 KHz	15.00 KHz

-If the above frequency signals are displayed longer than 5sec, it indicates Pressure S/W Error.

-Drain water for 3 minutes for that Error, and turn OFF water drain pump. Pressure S/W Error display “ IE” will be shown. .

10.Abnormal Water Temperature ERROR

-Water drain begins if abnormal water temperature is sensed at the initial time of water supply. If the frequency higher than 25.20KHz is sensed, water will be drained by force.

-Display : “CE”

-This error will be released by turning off Power S/W.

11.Natural Drain/Water Leak Error

-If more than 4 times of water supply and safe water level of Heater are sensed for each course, this error will occur.

-Display : “LE

-This error will be released by turning off Power S/W.

12.Tacho Error

-If Motor Tacho is abnormal, this error will occur.

-If Tacho signals are inputted less than 2 for 2sec after Motor started, this error will occur.

-Display : “3E”

-This error will be released by turning off Power S/W.

13.Motor TRIAC Short Error

-If Tacho signals are inputted more than 300 every 1sec in the operational interval less than 90RPM, this error will occur.

Turn off Power S/W at that time.

-Display : “bE”

-This error will be released by turning off Power S/W.

14.Thermistor Abnormal Error

-If Thermistor circuit is abnormal, this error will occur.

-If Thermistor is lower than 0.2V or higher than 4.5V, this error will occur.

-Display :”tE”

-This error will be released by turning off Power S/W.
