CIRCUIT DESCRIPTION
GENERAL DETAILS
· The low voltage transformer supplies the necessary voltage to the micom controller when power cord is plugged in. · When the door is closed, the primary switch is ON, the secondary switch is ON, and the monitor switch opens (contact COM and NO).
WHEN THE OVEN IS SET AT ANY LEVEL EXCEPT MAXIMUM.
· The micom controller controls the ON-OFF time of relay 2 by the applied signal to vary the average output power of microwave oven as POWER LEVEL. (refer to page 1-1) · One complete cycle of relay 2 is 22 seconds.
WHEN SELECTING COOKING POWER LEVEL AND TIME
· The micom controller memorizes the function you set. · The time you set appears in the display window. · Each indicator light turns on to indicate that the stage has been set.
WHEN THE DOOR IS OPENED DURING COOKING
· Both the primary switch and relay 2 are cut off primary winding voltage of the high voltage transformer. · ON-OFF of relay 2 is coupled electrically with opening and closing of the secondary switch. · When the door is opened, the secondary switch is opened and when the door is closed, the secondary switch is closed. · The cooking time stops counting down. · Relay stops functioning. · As the door is opened, if the contact of primary switch fails to open, the fuse opens due to the large current surge caused by the monitor switch activation, which in turn stops magnetron oscillation.
FUSE PRIMARY SWITCH
WHEN TOUCHING THE START PAD
· The coil of the relay is energized by the micom controller. · Power input is supplied to the high voltage transformer through the fuse to the primary switch and relay 2. · Turntable rotates.

SECONDARY SWITCH
· The fan motor rotates and cools the magnetron by blowing the air (coming from the intake on the baseplate). · The air is also directed into the oven to exhaust the vapor in the oven through the upper plate. · Cooking time starts counting down. · 3.2 volts AC is generated from the filament winding of the high voltage transformer. This 3.2 volts is applied to the magnetron to heat the magnetron filament through two noise-preventing choke coils. · A high voltage of approximately 2100 volts AC is generated in the secondary of the high voltage transformer which is increased by the action of the high voltage diode and charging of the high voltage capacitor. · The negative 4,000 Volts DC is applied to the filament of the magnetron.

MICROWAVE LEAKAGE TEST
CAUTIONS
· Be sure to check microwave leakage prior to servicing the oven if the oven is operative prior to servicing. · The service personnel should inform the manufacture importer, or assembler of any certified oven unit found to have a microwave emission level in excess of 5 mW/cm2 and should repair any unit found to have excessive emission levels at no cost to the owner and should ascertain the cause of the excessive leakage. The service personnel should instruct the owner not to use the unit until the oven has been brought into compliance. · If the oven operates with the door open, the service personnel should: - Tell the user not to operate the oven. - Contact the manufacturer. · The service personnel should check all surface and vent openings for microwave leakage. · Check for microwave leakage after every servicing. The power density of the microwave radiation leakage emitted by the microwave oven should not exceed 4 mW/cm2. Always start measuring of an unknown field to assure safety for operating personnel from radiation leakage.
MEASURING MICROWAVE ENERGY LEAKAGE
· Pour 275±15cc of 20±5°C(68±9°F) water in a beaker which is graduated to 600 cc, and place the beaker on the center of the turntable. · Set the energy leakage monitor to 2,450 MHz and use it following the manufacturer's recommended test procedure to assure correct result. · When measuring the leakage, always use the 2inch (5cm) spacer supplied with the probe. · Operate the oven at its maximum output. · Measure the microwave radiation using and electromagnetic radiation monitor by holding the probe perpendicular to the surface being measured Move probe along shaded area Probe scanning speed Less than 2.5 cm/sec ( 1in/sec)
5-1
MEASUREMENT WITH OUTER CASE REMOVED
· When you replace the magnetron, measure for microwave energy leakage before the outer case is installed and after all necessary components are replaced or adjusted. Special care should be taken in measuring the following parts. (Circled area of below Fig.) - Around the magnetron - The waveguide
NOTES WHEN MEASURING
· Do not exceed meter full scale deflection. · The test probe must be removed no faster than 1 inch/sec (2.5 cm/sec) along the shaded area, otherwise a false reading may result. · The test probe must be held with the grip portion of the handle. A false reading may result if the operator's hand is between the handle and the probe. · When testing near a corner of the door, keep the probe perpendicular to the surface making sure the probe horizontally along the oven surface, this may possibly cause probe damage.
WARNING : AVOID CONTACTING ANY HIGH VOLTAGE PARTS
RECORD KEEPING AND NOTIFICATION AFTER MEASUREMENT
· After adjustment and repair of any microwave energy interruption or microwave energy blocking device, record the measured values for future reference. Also enter the information on the service invoice. · The microwave energy leakage should not be more than 4 mW/cm.sq. after determining that all parts are in good condition, functioning properly and genuine replacement parts which are listed in this manual have been used. · At least once a year, have the electromagnetic energy leakage monitor checked for calibration by its manufacturer.
MEASUREMENT WITH A FULLY ASSEMBLED OVEN
· After all components, including the outer case, are fully assembled, measure for microwave energy leakage around the door viewing window, the exhaust opening, and air inlet openings. · Microwave energy leakage must not exceed the values prescribed below. NOTE: Leakage with the outer case removed less than 5 mW/cm.sq. Leakage for a fully assembled oven (Before the latch switch (primary) is interrupted) with the door in a slightly opened position-less than 2 mW/cm.sq.
5-2
MEASUREMENT OF MICROWAVE POWER OUTPUT
· Microwave power output measurement is made with the microwave oven supplied at its rated voltage and operated at its maximum microwave power setting with a load of (1000 ± 5)g potable water. · The water is contained in a cylindrical borosilicate glass vessel having a maximum material thickness of 3 mm and an outside diameter of approximately 190 mm. · The oven and the empty vessel are at ambient temperature prior to the start of the test. · The initial temperature (±1) of the water is (10±2)°C. It is measured immediately before the water is added to the vessel. After addition of the water to the vessel, the load is immediately placed on the center of the shelf which is in the lowest position and the microwave power switched on. · The time T for the temperature of the water to rise by a value T of (10±2)°K is measured, where T is the time in seconds and T is the temperature rise. The initial and final water temperatures are selected so that the maximum difference between the final water temperature and the ambient temperature is 5°K. · The microwave power output P in watts is calculated from the following formula: P=
4187 X (T) + 0.55 X (T2 - T0) X M T
· T2: Temperature after heating · T0: Temperature of bowl · M: Weight of bowl is measured while the microwave generator is operating at full power. Magnetron filament heat-up time is not included. · The water is stirred, to equalize temperature throughout the vessel, prior to measuring the final water temperature. · Stirring devices and measuring instruments are selected in order to minimize addition or removal of heat.
