DESCRIPTION OF OPERATING SEQUENCE
4.1
Variable power cooking control
HIGH VOLTAGE INVERTER POWER SUPPLY (U) controls
output power by a signal from Digital Programmer Circuit (DPC).
Power relay 1 stays on to supply power to the inverter circuit.
The outpower is controlled by the drive signal level from the
inverter circuit.
NOTE 1: 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.
NOTE 2: If microwave cooking is over 8 minutes with HIGH
power, fan motor rotates for 1 minute after cooking to cool
oven and electric components.
4.2
Grill cooking
The digital programmer circuit operates power relay 4 in the
sequence as shown in the table
4.3
Combination cooking
Combination cooking is accomplished by microwave and grill
cooking. The digital programmer circuit controls ON-OFF time of
power relay 4 and the inverter control signal level, as shown in
the table.
NOTE: After grill and combination cooking, fan motor
rotates for 1 minute to cool oven and electric components.
4.4
Autoweight defrost, autoweight cook
When those auto control feature is selected and Start pad is
pressed:
1. The digital programmer circuit determines the power level
and cooking time to complete cooking and indicates the
operating state in the display. The table shows the
corresponding cooking times for respective weight by
categories.
2. When cooking time in the display window has elapsed, the
oven turns off automatically by the controlled signal from the
digital programmer circuit.
NOTE: After one touch menu and auto reheat cooking, fan
motor rotates for 1 minute to cool oven and electric
components.
