DESCRIPTION OF OPERATING SEQUENCE
1. Variable power cooking control
The coil of power relay B (RY2) is 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 tine of power relay B contacts in order to vary the output
power of the microwave oven from “Warm” to “High” power. One
complete ON and OFF cycle of power relay B is 22 seconds.
The relation between indications on the control panel and the output of
the microwave oven is as stiown in table.
NOTE: The ON/OFF time ratio does not correspond with the percentage
of microwave power since approximately 2 seconds are required
for heating of magnetron filament.
2. Cyclic defrost/MULTI-STAGE DEFROST
When defrost power and defrosting time is selected and Start pad is
touched:
(A) 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.
(B) During defrosting power periods, power relay B is energized for 9
"seconds and de-energized for 13 seconds by DPC.
(C) During Standing periods, power rélay B is always open 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 fast standing time period.
Example: lf Defrosting time is selected for 5 minutes, each operating
period will be as follows :
5 minutes = 300 seconds
300/8 = 37 and remainder is 4 seconds.
The 4 seconds is added to the last time period.
NOTE: When defrosting time is selected for not more than 7 seconds, the
power'relay B will not be energized at all.
3. Auto/Automatic weight defrost, Auto/Programmed
reheat control
When those Auto Control feature is.selected and the Start Pad is tapped:
(A) The digital programmer circuit determines the power level and
cooking time to complete cooking and indicates the operating state in
the display window.
Table shows the corresponding cooking times for respective serving
by categories.
(B) When cooking time in the display window has elapsed, the oven turns
off automatically by a controll signal from the digital programmer circuit.
