MICOM FUNCTION

2-8. Control of variable type of freezing room fan

1. To increase cooling speed and load response speed, MICOM Vadably controls freezing room tan motor at the high speed

of RPM and standard RPM.

2. MICOM only operates in the input of initial power or special freezing operation or load response operation for the high

speed of RPM and operates in the standard RPM in other general operation.

3. If opening doors of freezing / cold storage room or home bar while fan motor in the freezing room operates, the freezing

room fan motor normally operates (If being operated in the high speed of RPM, it converts operation to the standard

RPM). However, if opening doors of freezing room or home bar, the freezing room fan motor stops.

4. As for monitoring of BLDC fan motor error in the freezing room, MICOM immediately stops the fan motor by determining

that the BLDC fan motor is locked or poor if there would be position signal for more than 65 seconds at the BLDC motor.

Then it displays failure (refer to failure diagnosis function table) at the display part of refdgerator, perf_ms re-operatldn in

the cycle of 30 minutes. If normal operation is performed, poor status is released and refdgerator returns to the initial

status (reset).

2-9. Control of M/C room fan motor

1. The M/C room fan motor performs ON/OFF control by linking with the COMP.

2. It controls at the single RPM withe_ varying RPM.

3. Failure sensing method is same as in fan motor of fi-eezing fan motor (refer to failure diagnosis function table for failure

display).

2-10. Door opening alarm

1. Buzzer generates alarm sound if doors are not closed even when more than a minute consecutively has passed with

doors of freezing / cold storage room or home bar opened.

2. Buzzer rings three times in the interval of 0.5 second after the first one-minute has passed after doors are opened and

then repeats three times of On/Off alarm in the cycle of every 30 seconds.

3. if all the doors of freezing / cold storage room or home bar are closed dudng door open alarm, alarm is immediately

released.

MICOM FUNCTION

2-13. Frost removal function

1. Frost removal is performed whenever total operation time of compressor becomes 7 ~ 7.5 hour.

2. In providing initial power (or returning power failure), frost removal starts whenever total operation time of compressor

becomes 4 ~ 4.5 hour.

3. Frost removal is completed if temperature of a frost removal sensor becomes more than 5°C after starting frost removal.

Poor frost removal is not displaced if it does not arrive at 5°C even if two hours have passed after starting frost removal.

4. No removal is done if frost removal sensor becomes poor (snapping or short-circuit).

2-14. Sequential operation of built-in product

Built-in products such as compressor, frost removal heater, freezing room fan, Cooling Fan and step motor damper are

sequentially operated as follows for preventing noise and part damage occurred due to simultaneous operation of a lot of

parts in applying initial power and completing test.
