Variable power cooking control

The coil of power relays are energized intermittently by the

digital programmer circuit, when the oven is set at any power

selection except for High power position. The digital

programmer circuit controls the ON-OFF time of the power

relays contacts in order to vary the output power of the

microwave oven. The relation between indications on the

control panel and the output power of the microwave oven is as

9.1. Defrost control

When defrost power and defrosting time is selected and Start

pad is touched:

1. The digital programmer circuit (DPC) divides the total

defrosting time into 8 equal periods, consisting of four

defrosting periods, each followed by a standing period.

(See figure)

2. During defrosting power periods, power relay ON-OFF time

is controlled at Low power mode by DPC.

3. During Standing periods, power relay is always open

shown in table.

NOTE:

ON-OFF time of power relays are changed by digital

programmer circuit when remaining cooking time or

selected cooking time are within 8 minutes at MED,

LOW and Defrost cooking mode.

resulting in no microwave power.

NOTE:

Defrost time selected is converted into seconds by the

DPC but display will show selected time in minutes and

seconds as programmed. The total number of seconds

is divided into 8 time periods. The remainder (seconds

not equally divisible by 8) are added to the last standing

time period.

9 DESCRIPTION OF OPERATING SEQUENCE

NE-3280 / NE-2180 / NE-2180C

Unlike many other appliances, the microwave oven is high-

voltage, high-current equipment. Though it is free from danger

in ordinary use, extreme care should be taken during repair.

CAUTION

Servicemen should remove their watches whenever working close to or

replacing the magnetron.

10.1. Check the grounding

Do not operate on a 2-wire extension cord. The microwave

oven is designed to be used when grounded. It is imperative,

therefore, to make sure it is grounded properly before

beginning repair work.

10.2. Warning about the electric

charge in the high voltage

capacitor (

Figure).

For about 30 seconds after the oven is turned off, an electric

charge remains in the high voltage capacitor. When replacing

or checking parts, remove the power plug from the outlet and

short the terminal of the high voltage capacitor (terminal of lead

wire from diode) to chassis ground with and insulated handle

screwdriver or insulated jumper lead wire to discharge.

WARNING

There is high-voltage present, with high-current capabilities in the

circuits of the high voltage winding and filament winding of the high

voltage transformer. It is extremely dangerous to work on or near these

circuits with oven energized.

DO NOT measure the voltage in the high voltage circuit including

filament voltage of magnetron.

WARNING

Never touch any circuit wiring with your hand nor with an insulated tool

during operation.

10.3. When parts must be replaced,

remove the power plug from

the outlet.

10.4. When the 15 Amp. (NE-

2180/NE-2180C) or 20 Amp.

(NE-3280) fuse is blown due to

the operation of interlock

monitor, replace the necessary

components according to the

following table.

10.5. Avoid inserting nails, wire, etc.

through any holes in the unit

during operation.

Never insert a wire, nail or any other metal object through the

lamp holes on the cavity or any other holes or gaps, because

such objects may work as an antenna and cause microwave

leakage.

Note before measuring

1. Do not exceed meter full scale deflection Leakage monitor

should initially be set to the highest scale.

2. To prevent false readings the test probe should be held by

the grip portion of the handle only and moved along the

shaded area shown in Figure right no faster than 1 inch/sec

(2.5cm/sec)

3. Leakage with the outer panel removed less than

5mw/square centimeter

4. Leakage for a fully assembled oven with door normally

closed less than 2mw/square centimeter

5. Leakage for a fully assembled oven [Before the interlock

switch (primary) is interrupted] while pulling the door less

than 2mw/square centimeter

1. Pour 275±15cc (9ozs ±1/2oz) of 20 ± 5°C (68 ± 9°F) water

in a beaker which is graduated to 600cc, and place the

beaker in the center of the oven.

2. Set the radiation monitor to 2450MHz and use it following

the manufactuer’s recommended test procedure to assure

correct results.

3. When measuring the leakage, always use the 2 inch (5cm)

spacer supplied with the probe.

4. Press the start button and with the magnetron oscillating,

measure the leakage by holding the probe perpendicular to

the surface being measured.

1. Measurement with the outer panel removed.

Whenever you replace the magnetron, measure for

radiation leakage before the outer panel is installed and

after all necessary components are replaced or adjusted.

Special care should be taken in measuring around the

magnetron.

WARNING

Avoid contacting any high voltage parts.

2. Measurements with a fully assembled oven.

After all components, including the outer panel are fully

assembled, measure for radiation leakage around the door

periphery, the door viewing window, the exhaust opening

and air inlet openings.

14.3. Record keeping and

notification after measurement

1. After any adjustment or repair to a microwave oven, a

leakage reading must be taken. Record this leakage

reading on the repair ticket even if it is zero.

A copy of this repair ticket and the microwave leakage

reading should be kept by repair facility.

2. Should the radiation leakage be more than 2mw/square

centimeter after determining that all parts are in good

condition, functioning properly, and genuine replacement

parts as listed in this manual have been used, immediately

notify PASC or PSC.

14.4. At least once a year, have the

radiation monitor checked for

calibration by its

manufacturer.

15 TROUBLESHOOTING GUIDE

CAUTION

1. Check grounding before checking for trouble.

2. Be careful of the high voltage circuit.

3. Discharge high voltage capacitor.

4. When checking the continuity of the switches or the high voltage transformer, disconnect one lead wire from these parts and then check

continuity with the AC plug removed. To do otherwise may result in a false reading or damage to your meter.

When disconnecting a plastic connector from a terminal, you must hold the plastic connector instead of the lead wire and then disconnect it,

otherwise lead wire may be open or the connector cannot be removed.

5. Be sure to ground any static electric charge built up in your body, before handling the D.P.C.

6. A 208-230V AC is present at the shaded area ( ) of the power supply circuit board (Terminals of power relays and primary circuit of low voltage

transformer). When troubleshooting, be cautious of possible electrical shock hazard.
