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.
