THE MICROWAVE SYSTEM

31

high-voltage transformers are most likely wired in- phase. As a last check, energize the Microwave System and verify the voltages between the taps on each high-voltage transformer. The wiring issue must be corrected prior to returning the oven to service, as the voltages must be:

†NORTH AMERICA: 208 VAC between 1 & 2 and

240 between 1 & 3.

†LATIN AMERICA: 220 VAC

†JAPAN: 200 VAC

†INTERNATIONAL: 230 VAC

N O T E : The terminals with the orange dot or the orange wire always go to terminal 3 on USA models.

Wiring the Filament Transformers

The installation of filament transformers is straightforward. Filament transformers are wired in-phase and in-line. Refer to the schematics on pages 55-63, detailing the proper wiring. Specifically, FT1 and FT2 are located in the middle-far right edge of the schematics.

To verify correct wiring (North America), meas- ure the voltages between terminals 1 & 2 and 1 & 3 on FT1 and FT2. The voltages must be 208 and 240 VAC respectively.

N O T E : The terminals with the orange dot or the orange wire always go to Terminal 3 on US models.

To verify correct wiring (International), measure the voltage between the taps on FT1 and FT2. The volt- age must be 220 VAC (Latin America), 200 VAC (Japan), or 230 VAC (International).

MEASURING RF LEAKAGE FOR MICROWAVE SAFETY

An RF (microwave) leakage test must be performed at the conclusion of the following service tasks:

†Door removal, replacement and/or adjustment

†Wave guide removal and/or replacement

†Magnetron removal and/or replacement

F I G U R E 23: Microwave Survey Meter Placement

W A R N I N G : If the unit fails the radiation test (leakage greater than 4 mW/cm2), the

oven must be taken out of service immediately until the defect is corrected. In addition, the CDRH Regulations 21 Subpart C, 1002.20 requires that leakage readings of over 4 mW/cm2 must be reported to the manufacturer.

Procedure for Measuring RF Leakage

1.Place the oven in WARM UP and allow it to warm up to the set temperature (CCSP). This should take approximately 13 minutes if the oven is starting out cold.

2.Once the oven has warmed up, place the oven into TEST MODE (see page 14). Place a water load into the cook cavity. Water load must con- form to the following specification:

a.Volume: 275ml ± 15ml

b.Temperature: 68 ± 9ºF (20 ± 5ºC)

c.Vessel: Low form, 600 ml beaker with an inside diameter of approximately 3.35” (85 mm) and made of Pyrex or glass ceramic.

3.Position the microwave survey meter as shown in Figure 23.

4.Press and hold the MGTRON soft key to energize the Microwave System.
