2°4. Ice Ejection Control Function

1. This is to eject ice from ice maker cube mould after ice making is completed.

2. if Hall IC signal is on within 3.6 seconds after ice ejection motor rotates in normal direction, it does not proceed ice ejection but waits, If the ice bank is full ice ejection motor rotates in normal direction in every hour to check the condition of ice bank. If the ice bank is not full, the water supply control starts after completion of ice ejection control. If the ice bank

is full, ice ejection motor rotates in reverse direction and sops under ice making or waiting conditions.

3. if ice bank isnot full, ice ejection starts. The cube mould tilts to the maximum and ice is separated from the mould and ice

checking lever raises.

4. Ice ejection motor stops for 1 second if Hall IC signal changes from OFF (low) to ON (high) after 3.6 seconds when ice

ejecSon motor rotates in normal direction. If there is no change in Hall IC signals within 1 minute after ice e}ection motor operates, ice ejection motor stops as ice ejection motor or hall IC is out of order.

5. If ice ejection motor or Hall IC is abnormal, ice ejection motor rotates in normal direction to exercise initial operation. It resets the ice maker if ice ejection motor or Halt IC is normal.

6. The mould stops for 1 second at maximum tilted conditions.

7. The mould returns to horizontal conditions as ice ejection motor rotates in reverse direction.

8. When the mould becomes horizontal, the cycle starts to repeat: Water Supply ..* Ice Making * Ice Ejection .._Mould Returns to Horizontal

2-5 Test Function

1. It is to force the operation during operation test, service, and cleaning. The test switch is mounted under the automatic

ice maker. The test function starts when the test switch is pressed for more than 0.5 second.

2. Test button does not work during ice ejection and water supply. It works when it is in the horizontal conditions. If mould is full of ice during test function operation, ice ejection control and water supply control do not work.

3. When test switch is pressed for more than 0.5 second in the horizontal conditions, ice ejection starts irrespect of the mould conditions. Water shall be splashed it test switch is pressed before the water in the mould freezes. Water shall be supplied while the mould returns to the horizontal conditions after ice ejection. Therefore the problems of ice ejection,

returning to the horizontal conditions, and water supply can be checked by test switch. When test function performs normally, buzzer sounds and water supply shall carry out. Check it for repair if buzzer does not sound.

4. When water supply is completed, the cycle operates normally as follows: Ice making • Ice ejection • Returning to horizontal conditions , Water supply

5. Remove ice from the ice maker cube mould and press test switch when ice maker cube mould isfull of ice as ice ejection and water supply control de not work when cube mould is full of ice.

2-6. Other functions relating to freezer compartment door opening

1, When freezer door is open, ice dispenser steps in order to reduce noise and ice drop.

2. When freezer door is open during ice ejection and cube mould returning to horizontal condition, ice ejection and cube

mould level return proceed.

3. When freezer door is open, geared motor and cube ice solenoid immediately stop and duct door solenoid stops after 5

seconds.

4. Water dispenser stops in order to protect water drop when freezer door is open.

5. Test function operates normally irrespect of refogearator cempadment door opening.

ICE MAKER

MOTOR

The above ice maker circuit is applied to the GR-D267 and consists of the ice maker unit pert installed at the freezing room

and the ice maker ddving part of the main PWB. Water supply to the ice maker container is done by opening the valve for the established water supply time by operating the

container via a solenoid relay for the ice valve of the solenoid valve placed at the M/C room. If the water supply time is elapsed, water supply is automatically stop. This circuit is a circuit for implementing function such as ice removal, ice-full detection, horizontal balancing end sense of ice-making temperature for the ice*maker container. Since ice-making temperature sense is same as Jnthe temperature sense circuit part of the main PWB, refer to it.

Test switch input detection of the ice-maker is same as in the door switch input detection circuit of the main PWB.

1. This function is used in operation test, service execution and cleaning etc and performed if pressing the test switch installed at the automatic ice-maker itself for more than 0.5 second.

2. The test switch operates in the horizontal status and test function is not input in the water supply operation. Ice removal control and water supply control is not performed if full-ice is arrived during the operation of test function.

3. If pressing the test switch for 0.5 second or more in the horizontal status, ice removal operation is immediately performed irrespective of the generation conditions of ice at the ice*making tray. Therefore, care is required since water may

overflow if operating test function in the water state that ice-making is not done. A cycle of water supply is performed in the horizontal balancing operation after ice removal operation. Therefore, you can check any problem of ice removal operation, horizontal operation and water supply. In this case. if test function is normally performed, "Ding~" buzzer sound rings and water supply control is performed. Thus, no ringing of"Ding~" buzzer sound means failure and repair check must be performed.

4. If water supply is completed, operation in the normal cycle of "ice making -_ ice removal , returning to hodzontst status

* water supply".

EXPLATION FOR MICOM CIRCUIT

1. Explanation for PWB circuit

1-1. Power circuit

Power circuit consists of SMPS (SWITCHING MODE POWER SUPPLY) power. The SMPS consist of the rectifying part (BDI, CE1) converting AC voltage to DC voltage, the switching part (IC2) switching the converted DC voltage, transformer

transferring energy of the primary side of the switching terminal to the secondary side and the feedback part (IC3. IC4)

transferring itto the primary side.

Caution : Since high voltage (DC310V) is maintained at the power terminal, please take a measure after more than 3

minutes have passed after removing power cords in the abnormal operation of a circuit.

Voltage of every part is as follows:

Voltage 230 Vac 310 Vdc 16 Vdc 12 Vdc 15.5 Vdc 5 Vdc

1-2. Oscillation circuit

Oscillation circuit is a circuit with the purpose of generating basic time for clock occurrence for synchronization and time

calculation in relation with information transmission/reception of inside elements of IC1 (MICOM). The OSCl must always

use rated parts since if SPEC is changed, time calculated at the IC1 may be changed or no operation is done.

1-3. Reset circuit

The reset circuit is circuit allowing various parts such as RAM inside of MICOM (ICl) to initialize and the whole of function to

start from the initial status, when initial power is input or when power is applied again to MICOM by a spontaneous power failure. 'LOW' voltage is applied to the reset terminal of MICOM in the beginning of power supply for a constant time (t Ores). Reset terminal during general operation is 5V (No MICOM operates in failure of RESET IC).

1. Load driving circuit

In even if opening the door of freezing room or cold storage room during operation of fan motor at the freezing room, this circuit does not stop and operates at the standard RPM. In addition, if doors of freezing room or cold storage room, the fan motor normally operates at the RPM previously operated.

(A). (B), (C) and (D) of door switch for the freezing room or cold storage room are connected to the door open sensing circuit in parallel toward both ends of switch to determine door open at MICOM.

_€Since a door switch of the home bar is connected to door switch (C), (D) of the cold storage room, it senses door opening

if even one of both is opened. The fan motor is immediately stop if opening doors of the freezing room or cold storage room at the TEST mode and it

immediately operates if closing them.
