    CIRCUIT DESCRIPTION 12-1) POWER Terminal Oscillation Frequency ● Vcc(DC 5V) MICOM POWER AND SENSORS << BLDC BLDC MOTOR POWER(NOT USE) +12V(DC 12V) RELAY,PANEL POWER ● When turned on, rectified AC voltage which is stepped down on 2nd transformer flows between ① and ③ at about AC 15V, goes through the diode D101 and D104 is changed to DC, and provide constant 12V.

  • Page 84: 12-2) Oscillation Circuit

    CIRCUIT DESCRIPTION 12-2) OSCILLATION CIRCUIT Terminal Oscillation Frequency Xin(#19) 8.0MHz Xout(#18) 8.0MHz ● It is an Oscillation Circuit for synchronism clock generation and time calculation on the information sending & receiving of the MICOM internal logic elements and when specifications for Resonator change, the timing system of MICOM changes resulting in errors.

  • Page 85: 12-5) Door Switch Detecton Circuit

    CIRCUIT DESCRIPTION 12-5) DOOR SWITCH DETECTON CIRCUIT 1) If R-Door is opened, the contact point of the door switch (4-3) becomes open, and the current of PCB line comes through R404 and R405 and provides 5 volt which is recognized as door is opened, and turn off the fan at different load.

  • Page 86: 12-6) Temp Sensing Circuit

    CIRCUIT DESCRIPTION 12-6) TEMP SENSING CIRCUIT 1) Sensor uses a thermistor which has a temp coefficient of negative resistance and controls resistance. When the heat goes up, the resistance gets down and vice versa. R302, 4, 6, 9 and C301~C303, C305 are parts for noise prevention but they are not related to temp sensing characteristics.

  • Page 88: 12-7) Damper Circuit

    CIRCUIT DESCRIPTION 12-7) DAMPER CIRCUIT 1) The temperature of R-room is controlled by opening and closing of damper with stepping motor, supplying & blocking cold air. 2) TA7774P (IC07) operates the damper. TA7774P is the driver IC only for step motor. If the regular signal is provided to TA7774P from Micom, send combined signal to Quad-Polar step motor to rotate on certain direction.

  • Page 89: 12-8) Display Circuit

    CIRCUIT DESCRIPTION 12-8) DISPLAY Circuit 1) KEY SCAN When Grid #6 is output, this signal goes through PCB resistance 10 ㏀ and provided to power frequency. When the switch is pressed, R502(6.8 ㏀) and R501 (12 ㏀) decrease the signal and less than 5.1V peak to peak signal is provided to MICOM, the MICOM recognizes the grid #6 is provided, and change the function corresponding to switch key.

  • Page 90: 12-9) Load Control Circuit

    CIRCUIT DESCRIPTION 2) DISPLAY OPERATION Like the signal diagram below, Micom sends “ high ” signal through MICOM 6 terminals of NO #1→ 2 → 3 → 4 → 5 → 6 for 2ms every 12ms. This signal goes to output terminal via input terminal of IC5 (KID65783AP or TD62783AP).
  • Page 91 CIRCUIT DESCRIPTION 1) Main PCB processes most of the load control for electronic refrigerators. 2) Compressor, F-Room, defrost heater, and other functions are controlled with relay. 3) For example, to operate compressor, MICOM 29 pin outputs high (5V) signal which goes into IC3 Pin #4. The IC3 pin NO 4 plays the same role as the base of NPN TR.
