THEORY OF OPERATION

MICROWAVE OPERATING SEQUENCE

OFF CONDITION

Closing the door activates the secondary (door
sensing) interlock switch, and the primary in-
terlock switch. The monitor switch contacts are
opened.

When  the  oven  is  plugged  in,  120  VAC  is
supplied to the control unit (see the illustration
below).

1.

The display will show  “

WELCOME

.” To

set any program or set the clock, you must
first touch the STOP/CLEAR keypad. The
display  will  clear,  and  a  colon  (  :  )  will
appear.

POWER LEVEL (P-0 TO P-90)
COOKING

When  “Variable  Cooking  Power”  is  pro-
grammed, 120 VAC is supplied to the power
transformer intermittently through the contacts
of relay RY2, which is operated by the control
unit within an interval second time base.

NOTE: The ON/OFF time ratio does not corre-
spond  with  the  percentage  of  microwave
power, because approximately 3 seconds are
needed for heating of the magnetron filament.
