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 OSC1 must always use rated parts since if SPEC is changed, time calculated at the IC1 may be changed or no operation is done. <GR-P247, L247, P207, L207> <GR-C247, B247, C207, B207>

1-3. Reset circuit

The reset circuit is circuit allowing various parts such as RAM inside of MICOM (IC1) 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 (10ms). Reset terminal during general operation is 5V (No MICOM operates in failure of RESET IC). <GR-P247, L247, P207, L207> <GR-C247, B247, C207, B207>

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 is not 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 ejection motor rotates in normal direction. If there is no change in Hall IC signals within 1 minute after ice ejection 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 Hall 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 Maximum tilting point Bank is not full HALL IC OUTPUT SIGNALS Bank is full HALL IC OUTPUT SIGNALS ICE CHECKING LEVEL 30 ICE CHECKING AXIS

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 if 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 is full of ice as ice ejection and water supply control do not work when cube mould is full of ice.
