● 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.
- To protect the Gear by releasing its stress a second later after the above directions, rotate the Eject
Motor clockwise for 2ms.
- 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.
