OPERATING INSTRUCTIONS & INSTALLATION

3-1) DISPLAY DESIGN

1) Freezer Temp Setting 1-1) With the initial power on, Freezer will be set at MID (-4°F/-20°C) and Refrigerator will be set at MID

(37°F/3°C) automatically. At this time, the number of LEDs (1 ~ 5) lighting up on the display panel means intensity (MIN ~ MAX) of room control temperature (6.8 ~ -13°F/-14 ~ -25 °C) and as the intensity gets increased, the number of LEDs increases and the set temperature become lowered.

1-2) Freezer Temp can be set from (6.8°F/-14°C)(MIN) to (-13°F/-25°C)(MAX) with Freezer temp setting button.

2) Refrigerator Temp Setting 2-1) Refrigerator Temp can be set from (44.6°F/7°C)(MIN) to (33.8°F/1°C)(MAX) with Refrigerator temp setting

button.

2-2) Refrigerator set temp varies slightly from actual temperature according to the user’s way of storing food

and peripheral temp. (If food is stored too close to Refrigerator Temp Sensor, it can block air circulation resulting in weak or over cooling. So, be careful not to block it.)

Note) When power is out due to an instant power failure or the problems in an electric circuit and restored

again, the ref checks Refrigerator Temp. At this time, When Freezer Temp is lower than (41°F/5°C) , Refrigerator considers it as an instant power failure and restores the previous temp and functions stored in EEPROM for use.

Note) When taking out ice with ICE OFF selected, only ice lefted in the storing box is extracted.

2) FILTER RESET 2-1) When FILTER INDICATOR LED on the front Panel becomes orange or red, Filter should be changed.

2-2) - When FILTER RESET button is pressed for a certain period (3sec) after changing Filter, FILTER

INDICATOR LED becomes green with “ Ding Dong ” sound. (When FILTER RESET is pressed, water count is reset to 0)

- When the filter is replaced,reset the indicator by pressing the FILTER RESET button for 3 second at the same time.

2-3) After Filter reset, when 270 Gallon water is used (including water used in making ice), FILTER

INDICATOR LED becomes orange , and when 300 Gallon water is used, FILTER INDICATOR LED becomes red.

2-4) When the water filter is not needed due to the use of purified water or other reasons, the Filter Indicator

can be turned off. When pressing the Filter Reset Button for 5 seconds continuously, the Filter Indicator will be off with a "Ding Dong" sound. (At this time, when 3 sec has passed, the filter will be reset with a "Ding Dong" sound and when 5 sec has passed, the Filter Indicator will be off.)

2-5) When the Freezer temperature is higher than 41 °F upon the initial power on, the Filter Indicator will be

turned on. And, when it is lower than 41 °F, it will display the previous setting (before the power off).

3-5) ICE DISPENSER & WATER DISPENSER

● Among the functions depending on Peripheral Temp, Comp Cooling Fan (Comp Room Fan) is controlled

according to Peripheral Temp as follows. Therefore, make sure to check the contents to refer to during A/S because Cooling Fan can operate or not according to conditions during Comp operation.

1) Initialization (Restoration to the initial horizontal status) When the Ice Maker is initialized by Power On or the Ice Error Mode, the Ice Tray gets leveled again by

rotating the Eject Motor regardless of the horizontal state of the Ice Tray.

1-1) Conditions for Initialization

- After pending time (5sec.) for activation of each MICOM port with the initial Power On or the Power On after Power Failure.

- When an error occurs due to full icing or the restraint of the Eject Motor, it starts initialization in 24 hours

upon full icing and in an hour upon the counter-rotation error of the Eject Motor.

1-2) Movement for Initialization

- Satisfy the initial horizontal status by counter-rotating the Eject Motor.

- When the voltage of the Motor Voltage Sensor becomes above 0.55V during counter-rotation of the

Eject Motor, the counter-rotation stops.

- When it is not detected that the Motor Voltage Sensor becomes more than 0.55V for a minute after

the counter-rotation, it is considered as an error and initialization gets started again in an hour.

- It stands by for the initial Ejection for a cycle (2 hours) after completion of initializing movement by Power

On and it stands by for normal Ejection after completion of initializing movement by error.

- After the Ejection Stand-by time has passed, check the temp of the Ice Tray and if the temp reaches

to the Ejection temp, it carries out the Ejection.

2) Water Supply It is the movement to supply water on the ICE-TRAY by using the SOLENOID VALVE after the completion of the ejection (Ejection after the completion of the normal ice making or that by the test movement) Considering cases with low hydraulic pressure, when it is recognized as No Water Supply, the Water Supply will be attempted for 4 times.

2-1) Specifications for water supply

- After the completion of the normal ejection and the opening of the water supply valve, water is supplied for the previously set OPTION time (Set by the DIODE in PCB and normally for 5 sec) and the water supply valve gets off.

- Water is supplied regardless of the F/R-DOOR OPEN

- While supplying water, the ICE TEST S/W doesn’t work.

- In one min. and 30 sec. after the completion of water supply, Water Supply/ No Water Supply will be judged.

- Under the condition of additional water supply due to No Water Supply, the additional water supplying time is 1.5 sec, 1 sec, and 2 sec.

- When judging water supply after the trial of water supply within the number of previous water supply, complete water supply. In this case, the Ejection Stand-By Time is 58(65) min.

- To prevent the additional water supply by the judgment of No Water Supply due to the ice cube on the tray cube which the ice maker sensor of the ICE-TRAY is, quit the water supplying movement for one time when it is judged as No Water Supply after trying to supply water as many as the number of the previous water supplying. After POWER ON, the number of the previous water supplying will be considered as once for the first water supplying and when No Water Supply is judged after the initial water supplying, quit the water supply movement. If the number of the previous water supply is three times, supply water for 3 times, and when judged as No Water Supply, quit the water supplying movement. In this case, the Ejection Stand-By Time is 70~110 min.

- When judged as No Water Supply in the previous water supply, supply water for 5 sec, 1.5sec, 1sec,and 2 sec for 4 times.

- According to conditions, the Ejection Stand-by Time is as follows.

2-2) Judgment of Water Supply by the ICE-TRAY Temp sensor

- In one and a half min after the completion of the water supply, judge either the Water Supply or the No Water Supply by comparing the temp change of the ice maker sensor on the ICE TRAY.

- In the case that the temp of the ICE-TRAY ice maker sensor in one and a half min. after the completion of the water supply is 2 degrees (5 COUNT) higher than that during the water supply movement, it is judged as the Water Supply and when the temp increases or decreases less than 2 degrees, it is considered as the No Water Supply.

2-3) Specifications of water supply movement upon pressing the Ice Test S/W

- Supply water for once regardless of the previous water supply.

- The Ejection Stand-by Time after the completion of water supply is the same as that after the completion of the previous water supply movement regardless of the Water Supply/ No Water Supply recognition.

- Do not change the number of the previous Water Supply. That is, if the number of Water Supply before pressing the ICE TEST S/W is 3 times, that of the previous Water supply after the completion of the Water Supply by pressing the ICE TEST S/W is also 3 times.

3) Ice Making It is until the water in the ICE-TRAY after the completion of Water Supply gets frozen completely and the ice

making movement is completed by the temp of the ice making temp pickup part using the ice maker sensor (THERMISTOR).

3-1) After water is supplied to the ICE-TRAY, check the temp pickup part of the ice maker sensor after the

Ejection Stand-By Time for 58(58~110) min. (For the No Water Supply, 90 min) and judge whether the temp of the ice maker sensor is below (1.4°F/-17°C).

3-2) If the ice maker sensor maintains the temp below (1.4°F/-17°C) for 5 min. It is judged that ice making is

completed. However, do not check the ice maker sensor within the Ejection Stand-By Time from the point of Water Supply. (Protection function when the sensor is faulty or the cold air leaks.)

3-3) Stand-by for 1 CYCLE: After the completion of the initialization by POWER ON, it stands by for 1 CYCLE

(2hr.) and operates the Ejection although the temp condition of the ice maker sensor is satisfied.

3-4) As long as the temp of the temp sensing part maintains below (1.4°F/-17°C) for more than 5 min, the

Ejection will be carried out. If the temp fluctuates below (1.4°F/-17°C) above (1.4°F/-17°C), the Ejection will be carried out after 5 min. at the temp below (1.4°F/-17°C) while counting the Stand-by Time entering the temp below (1.4°F/-17°C).

4) Ice Ejection It is the movement to separate the ice cubes from the ICE-TRAY after the completion of ice making, which is conducted by the following steps. Check the changes in status and time for the horizontal S/W (if it is used) and the ice level check S/W in parallel and then operate Ejection. At this point, the regular rotational direction of the motors is clockwise (CW) and the reverse rotational direction of that is counter clockwise (CCW). The Ice Ejection is carried out twice, which is to separate all the ice cubes from the ICE-TRAY.

4-1) Detailed movements by step during the Ejection.

- 1

step: Ejection temp checking step Check whether the temp of the temp sensing part is below (1.4°F/-17°C) and whether the Ejection StandBy Time after Water Supply has passed. At this point, when the F-Defrost goes into operation during the Ejection Standby, the Ejection Standby Time will be reset. Then, check that 58~110 min. has passed by recounting from the beginning after the completion of the Defrost. If the temp of temp sensing part of ice making become below (1.4°F/-17°C) and maintain it for 5 min, carry on the next step.

- 2

step: Filled up ice container checking step To check the ice level of the ice container, CHECK the ON/OFF (Low/High) of the ice level S/W If the ice level S/W is ON (Low), it means that the ice container is full and the Ejection stands by. And when the ice level S/W is turned OFF and 40 min. has passed, the Ejection will be carried out.

- 3

step: ICE TRAY overturning step (clockwise) It is the movement to turn over the TRAY to separate the ice cubes from the TRAY by rotating the Ejection motor clockwise for a certain time period. At this point, raise the guide ice to prevent the ice cubes from contacting the guide ice. Carry out the clockwise rotation for a minute from the start of the clockwise rotation or until the horizontal S/W is ON (Low) after 5 sec from the beginning of the third step when using horizontal S/W. If the door of the F-Room is open, stop the clockwise rotation and start the rotation after the door is closed. During the temporary pause, the clockwise rotation will not be counted.

- 4

step: Ice separating step (Standby for 2 sec. at the maximum twist point ) It is the movement to twist the tray again in the reversed state to separate the ice cubes from the tray completely and the tray receives torsion because the ICE-TRAY is stopped by the STOPPER. The ice cubes are separated by this strength and the tray stands by for 2 sec. at the maximum twist point for complete separation.

- 5

step: Reverting to horizontal level step (counter clockwise) Rotate the Ejection motor in reverse to revert the ICE-TRAY to the horizontal level. When using the horizontal S/W, reverse rotation begins. When the horizontal S/W is ON (Low) after 5 sec from the beginning of the reverse rotation or the voltage of the voltage sensing part of the motor is above 0.55V, the rotation will be stopped. At this point, the raised guide ice becomes lowered again and touches on the highest point of the stored ice for checking the ice level.

- 6

step: Motor initializing step (clockwise) After a sec. upon the completion of the 5

step, the Ejection motor rotates clockwise for 2ms to release the

stress of the gear as well as to protect it.

4-2) Errors and handling methods during the ejection

- If the conditions of the completion for the reverse rotation are not satisfied in a min. after applying the

counter rotation during the execution of the 5 steps of the detailed ejection movement, it is considered as an ERROR and stops the motor.

- If it is judged as an abnormal state, facilitate the initialization in an hour.

If the ejection error occurs 3 times consecutively, it is sensed as ERROR (ICE ERROR) and when selecting the self diagnosis, it turns on the corresponding LED.

- If the ejection operates normally, the ERROR value of the existing ice making function will be deleted.

OPERATING INSTRUCTIONS & INSTALLATION

4-3) Ejection Movement TIMING CHART

5) Ice Test It is necessary for the forced operation for the purpose of the operation test, A/S, and cleaning, and when

pressing the ICE TEST S/W for a certain time period (more than 1.5 sec.), it goes into operation.

5-1) The TEST button will not be selected during the Water Supply or the Ejection. Press it again with the

Water Supply or the Ejection completed to run the Test function. Standby for maximum 5 min. when Water Supply operates.

5-2) When the TEST button is selected, the ejection will be carried out by running the eject motor regardless of

the elapsed time (58~110 min.) after the Water Supply and the temp of the ice making. And after this, the tray will be reverted to the horizontal level and the ICE TRAY will be supplied with water.

5-3) It operates normally regardless of the Freezer/Refrigerator DOOR OPEN (No temporary pause functions

by the DOOR OPEN) 5-4) Other functions are the same as the movements of the Ejection and the Water Supply. 5-5) When ERROR occurs more than 3 times with the normal function and the ice making stops, the ICE TEST

shall operate. At this point, if the normal Ejection and Water Supply are operated by the TEST S/W, there

would be “Ding Dong” sound for once before the Water Supply and the third ERROR MODE will be

cancelled executing the normal ice making.

1) Freezer Defrost shall be determined by COMP ON total hour.

2) On the initial POWER ON, Defrost in Freezer will be operated after COMP ON total hour of 4 hr.

3) Defrost cycle changes automatically depending on the conditians MIN 6 hr, to MAX“11” hr

4) The judgment of defrost cycle shall be determined by peripheral temp, No. of DOOR OPEN in

Freezer/Refrigerator, and the time for DOOR OPEN in Freezer/Refrigerator.

5) Point of Defrost HEATER OFF is (59 °F/15 °C) by the temp value of Freezer Defrost SENSOR.

● If F Defrost HEATER doesn’t reach to the point of Defrost OFF in 70 min., turn off forcibly and complete

Freezer-Defrost. ( Prevention of inferior HEATER OPEN or inferior Refrigerator Defrost Sensor )

MICOM POWER AND SENSORS

BLDC MOTOR POWER(NOT USE)

RELAY,PANEL POWER

● When turned on, rectified AC voltage which is stepped down on 2nd transformer flows between ① and ③

at about AC 15V, goes through the diode D101 and D104 is changed to DC, and provide constant 12V. It provides 5V to MICOM and other circuits via regulator REG102 (MC7805ACT), and make entire PCB operate.

● When the power is applied,currents will be rectified via B and DC360V will be generated at the both terminals of

the capacitor (C001). The Top-Switch (TNY268P)will be automatically switched to the optimum state according to the secondary load conditions. When currents flow between Top-S/W D and S (5PIN~7PIN),there will be currents generated i n the TRANS and the currents i nduced to the TRANS upon power off between D and S will be transferred to the secondary.By repeating the above process, 12V will be maintained at the secondary C108 and it will be supplied to the display relay. Also, 5V will be generated at the C110 and it will be supplied to the sensor and operate the main PCB.

12-4) EEPROM DETECTION CIRCUIT

● A semiconductor memory EEPROM stores data

remembering previous settings regardless of power-off, which are indispensable especially in power fluctuating areas. Also, EEPROM sets and uses other options in principle.

CIRCUIT DESCRIPTION

12-2) OSCILLATION CIRCUIT

● It is an Oscillation Circuit for synchronism clock generation and time calculation on the information sending &

receiving of the MICOM internal logic elements and when specifications for Resonator change, the timing system of MICOM changes resulting in errors. (Rated parts must be used)

Terminal Oscillation Frequency

Xout(#18)

8.0MHz

12-3) RESET CIRCUIT

● RESET Circuit allows the whole program to go back

to the initial setting by initializing parts such as the RAM in MICOM with the power supply into MICOM or with an instant power failure.

Upon the power supply, the reset terminal voltage becomes "LOW" for tens of second compared to Vcc voltage(DC 5V) at MICOM, and it maintains "HIGH"(Vcc Voltage) during normal operation. But, when Vcc drops down to 3.4~3.7V, the reset terminal voltage becomes "LOW".

CIRCUIT DESCRIPTION

12-5) DOOR SWITCH DETECTON CIRCUIT

1) If R-Door is opened, the contact point of the door switch (4-3) becomes open, and the current of PCB line comes through R404 and R405 and provides 5 volt which is recognized as door is opened, and turn off the fan at different load. When the door is closed, the voltage goes out from R404 to Switch, the MICOM is applied with OV and the door is recognized as closed.

2) If F-Door is opened, the contact point of the door switch (4-3) becomes open, and the current of PCB line comes through R402 and R403 and provides 5 volt which is recognized as door is opened, and turn off the fan at different load. When the door is closed, the voltage goes out from R402 to Switch, the MICOM is applied with OV and the door is recognized as closed.

3) Q401 is the circuit to turn off the auger motor operation when the door is opened. If the door is closed, Vcc voltage of R402 works as ground via door switch, OV is applied to the base of Q401, and Q401 becomes operable, Vcc voltage on "A" part Q702 base works as emitter on Q401 collector and creates OV. (Check the operable condition for other parts at load terminals)

4) Condition for door open is the opposite of condition 3 above.

CIRCUIT DESCRIPTION

12-6) TEMP SENSING CIRCUIT

1) Sensor uses a thermistor which has a temp coefficient of negative resistance and controls resistance. When the heat goes up, the resistance gets down and vice versa. R302, 4, 6, 9 and C301~C303, C305 are parts for noise prevention but they are not related to temp sensing characteristics.

2) If Vf is the incoming voltage to MICOM in case of F-Sensor, Vf equals (Rth * Vcc)/ ((R301 + Rth). Where Rth is resistance of THERMISTOR corresponding to Temp. Please refer to the Appendix Temp-to-Sensor Resistance/Voltage conversion table(Temp-to-MICOM Terminal Voltage included) on A/S. (Next page)

CIRCUIT DESCRIPTION

12-7) DAMPER CIRCUIT

1) The temperature of R-room is controlled by opening and closing of damper with stepping motor, supplying & blocking cold air.

2) TA7774P (IC07) operates the damper. TA7774P is the driver IC only for step motor. If the regular signal is provided to TA7774P from Micom, send combined signal to Quad-Polar step motor to rotate on certain direction. This makes clockwise or counter clockwise rotation to make the damper open or close.

3) Since the damper always touches the cold air, DC 12V/1W heater is installed, always on to prevent the malfunction from moisture and is controlled on conditions. (Operation conditions can be changed). Micon #15 pin connected to IC4 controls the damper heater like category 3.

12-8) DISPLAY Circuit

1) KEY SCAN

When Grid #6 is output, this signal goes through PCB resistance 10 ㏀ and provided to power frequency. When the switch is pressed, R502(6.8 ㏀) and R501 (12 ㏀) decrease the signal and less than 5.1V peak to peak signal is provided to MICOM, the MICOM recognizes the grid #6 is provided, and change the function corresponding to switch key. [Refer the circuit diagram below]

CIRCUIT DESCRIPTION

2) DISPLAY OPERATION Like the signal diagram below, Micom sends “ high ” signal through MICOM 6 terminals of NO #1→ 2 → 3 → 4

→ 5 → 6 for 2ms every 12ms. This signal goes to output terminal via input terminal of IC5 (KID65783AP or TD62783AP). Output wave always goes through LED input terminal with DC11~12V on every period. At this time, if SINK signal comes out at IC4, DC11~ 12V is applied to LED input terminal and output terminal sinks to OV which turn on LED for 2ms For example, to turn on "Power Fre." LED, IC4 #16 pin sinks to 0V when IC5 #16 becomes DC 11~12V making "Power Fre" LED turn on.

󳢬 GRID WAVE PATTERN

12-9) Load Control Circuit

CIRCUIT DESCRIPTION

1) Main PCB processes most of the load control for electronic refrigerators.

2) Compressor, F-Room, defrost heater, and other functions are controlled with relay.

3) For example, to operate compressor, MICOM 29 pin outputs high (5V) signal which goes into IC3 Pin #4. The IC3 pin NO 4 plays the same role as the base of NPN TR. The pin #14 works as collector of TR. So, if 5V is supplied to pin #4 of IC3, the pin #15 turned on and connected to the ground. Then, the relay RY75 and coil connected to the pin #15 of IC3 becomes low (OV) and +12V (opposite side of coil) flows to the pin #15 of IC3 via coil and goes into the ground. While current flows to the coil, the magnetic power arise, it turns on the secondary contact point inside of RY75, and operates when the AC power is supplied to the both side of comp. When MICOM #29 Pin becomes Low(0V), IC3 #4 Pin becomes Low which makes Power cut and current of RY75 RELAY cut. So, secondary contact becomes off due to magnetic field cut, which makes Comp off.

4) All other loads work basically on same principle, defrost heater operates only on the condition that the compressor is turned off like the circuit above, and connected like the equivalent circuit below.

* Q702 is connected to the F door

switch to prevent PL accident due to continuous operation of motor when the auger motor control circuit is not working properly. It must be turned off when the door is opened.

CIRCUIT DESCRIPTION

1) The ice maker circuit above is to control the ice maker kit installed on the F room.

2) This circuit is the hardware to control ejection and horizontal positioning, ice making temperature detection and full icing detection. Temperature detection circuit is the same as temperature detection circuit on 4-6 and the explanation will be skipped and only the ejection circuit will be explained. If MICOM PORT #7 is outputted with High to rotate motor in ejection direction and the pin #2 of IC5 is inputted, 12V is outputted on pin #17 of IC5, goes to motor and supplied to pin #11 of IC4. As pin #8 of IC4 and eject MICOM port #7 are connected in common, 11 output port of IC4 gets on and the current flows into Ground making motor rotates. This motor rotates the gear and rotates the ejection tray. The tray twists to separate the ice from the tray and return to the horizontal state.

3) For restoration, motor stops for 2 seconds when the ejection is completed and to rotate in opposite direction, output horizontal MICOM port with high and perform horizontal positioning.

4) The test S/W is off in normal cases and MICOM PORT 63 stays high. When necessary, press the switch for more than 1.5 seconds making forced ejection executed. Full S/W has a lever that detects the amount of ice on ice-maker kit and based on the status of MICRO S/W connected to the lever, if the ice is full on the container, ejection is not executed, and only if it is off (MICOM PORT 61 is high), the ejection is executed.
