7 Description of the Operating Sequence
7.1 Variable power cooking control
The output power is controlled by the inverter power
supply. The level of output from the inverter circuit is
controlled by a pulse width modulated signal from the
digital programmer circuit (DPC). The digital program-
mer circuit operates relay RY1 to supply power to the
inverter circuit.
NOTE:
If the microwave cooking time is longer than 3
minutes, the cooling fan will operate for 1 minute to
cool the oven and its electronic components.
7.2 Auto weight defrost, Auto weight
Cook
When an auto control feature is selected and the start
pad pressed:
1. The digital programmer circuit determines the
power level and the cooking time and indicates the
operating state in the display. The table shows the
corresponding cooking times and weights for the
selected category.
2. When the cooking time in the display window has
elapsed, the oven turns off automatically via the
control signal from the digital programmer circuit.
Note: After auto cooking if the oven temperature
is over the predetermined temperature the fan
motor rotates to cool the oven and its compo-
nents.
