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:
