8. Circuit Descriptions

8-1. Division of power supply
Power supply Vcc (DC 5V) Vcc (DC 12V)
Used circuit Auxiliary power supply of MICOM and sensing part of SENSOR LED DISPLAY working part, RELAY working
AC inputed power is decompressed through DC-TRANS and the reduced volatage is converted to the DC voltage through rectifying DIODE. Then it becomes flat through 1000 F/35V CAPACITOR and through REGULATOR 7812, stabilized DC 12V output comes and it is used as power source for RELAY and DISPLAY.Also from this 12V, stabilized 5V output comes through REGULATOR7805 and used as power source for MICOM auxiliary circuit and various signals(SENSOR, S/W).
8-2. Division of RESET Circuit
Division of RESET circuit makes it possible that programed function of system is set to be initial state by initializing various parts such as RAM in MICOM when power is impressed or instantaneous electricity failure is occurred. RESET voltage at the impressed moment of power is maintained as LOW state for a few seconds and High under normal working condition.
8-3. Division of RESONATOR
The role of this circuit is generation of synchronous CLOCK for transmission/reception of informations of the logical elements inside MICOM and the basic time for the calculation of time. Rated parts must be used in the division of RESONATOR because the calculation time of MICOM is changed or cannot work if specification is changed.

8-4. Division of SENSOR

SENSOR and F-rated resistance are connected to the GROUND and DC 5V, respectively. The resistance value which is changed by the temperature is converted to the voltage, and then respective temperature is discriminated by input voltage to A/D PORT of MICOM
8-5. Division of OPERATING
If at MICOM PORT begins to output High signal which corresponds to electrical load which we intend to work, DRIVER IC(KA2657) is turned ON and at this moment, corresponding electrical load starts to operate because the DC12 yield the electric current which flows corresponding RELAY COIL and RELAY contacting point is set to be ON so corresponding electrical load begins to operate.

8-6. Division of BUZZER

TRANSISTOR begins to operate by CLOCK which was generated at MICOM and BUZZER sound is generated by impression of 12V to the BUZZER.
8-7. Division of DISPLAY, KEY SCAN
from MICOM #3-#7 GHID signal is generated for 10 sec with the period of 2 sec HIGH signal and for the lighting the corresponding LED, the CONTROL terminal of MICOM PIN #8-#11 output the output signal which is coincident with GRID signal. Meanwhile by pushing the KEY which is connected by respective GRID, corresponding signal is inputted to MICOM.

8-8. Division of OPTION

The output such as GRID wave form which is only generated at the initial POWER ON is accepted as input through SWITCHING DIODE and discriminate OPTION by matrix method. #23, #24, and #25 PORT of MICOM PORT generate the same output with GRID wave form only at initial POWER ON.

DOOR OPEN WARNING of refrigerator compartment alarms for 10 seconds after 2 minutes when DOOR opened initially. If the door is opened continuously it is alarmed for 10 seconds with a period of 10 seconds. Because the penetration of moisture or vapor into DOOR S/W causes the junction SHORT of DOOR S/W, the warning is alarmed continuously by judgement of MICOM which regards the DOOR as open state.In this case, DOOR is regarded as continuously opened state after 10 minutes and the lamp of refrigerator is set to be OFF. So if you open the DOOR, the lamp of refrigerator is maintained as OFF state. If the moisture or vapor penetrates into the junction and corrodes it, the lamp of refrigerator is kept as OFF state and DOOR OPEN warning does not work because the signal does not inputted to the MICOM.
