    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 70: 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 71: 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 72 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.
