PREHEATING CONDITION
Set the preheating temperature by turning the temperature
control knob (at 90°C to 25O"C), and preheating time at
20 minutes.
When the "Cooking Start" button is pushed the following
operations occur: (Figure 5).
1. The contacts @ - @ of convection timer and cook
switch are closed.
The fan motor, oven lamps and
turntable motor are energized.
2.
The contacts @ -@
of convection timer is closed.
The convection timer and convection lamp are energiz-
ed.
3.
The 220 volts A.C. is supplied to the sheath heater and
heater lamp through the thermostat.
4.
In case the temperature control is set at 40°C:
The contacts (COM)-(NC) of cam switch closed to
provide a current path to the convection motor
through the thermostat.
In case the temperature control is set at 90°C to
250°C:
The contacts (COM)-(NO) of cam switch closed to
provide a current path to the convection motor
through the convection timer contacts 0 - @ .
5.
When the temperature of the therm0 rod which is
mounted to the back oven cavity, rises above the
selected temperature, the circuit to the sheath heater
and heater lamp are de-energized by the thermostat.
But other components remain in operation. When the
temperature
of the therm0 rod drops below the
selected temperature, the 220 volts A.C. is supplied to
the sheath heater and heater lamp.
6.
The preheat temperature has been reached.
The sheath heater and heater lamp will cycle on and
off by thermostat to maintain the selected tempera-
ture .
CONVECTION COOKING CONDITION
When the preheat temperature is reached, open the door
and place the food to be cooked in the oven. Then set the
desired convection
temperature
and cooking time by
turning the temperature
control knob and convection
timer.
When the "Cooking Start" button is pushed, the following
operations occur:
1. The convection and heater lamps light.
2.
The fan motor, oven lamps, t.urntable motor, convec-
tion timer, convection motor and sheath heater are
energized.
3.
Upon completion of the selected cooking time, the
timer bell rings, and the all contacts of the convection
timer are deactivated.
The oven reverts to the OFF
condition.
Note: When both microwave and convection timers are
set, convection cooking takes place first.
In this case, the microwave operation will begin
automatically when the convection timer returns to
"0" position.
COMBINATION COOKING CONDITION
Set the preheating temperature and preheating time at 20
minutes.
When "Cooking Start" button is pushed, the following
operations occur:
1. The convection and heater lamps light.
2.
The fan motor, oven lamps, turntable motor, convec-
tion timer, convection motor and sheath heater are
energized.
3.
The 220 volts AC. is supplied to the sheath heater.
4.
When the oven temperature reaches to the selected
temperature, the convection lamp and sheath heater
will cycle on and off by thermostat.
5. Now, the oven is preheating condition;
When the preheat temperature is reached, open the door
and place the food to be cooked in the oven. Then set the
desired convection temperature and cooking time, desired
microwave cooking control and cooking time.
When the "Cooking Start" button is pushed, the following
operations occur:
1. First the oven is operating the convection cooking.
2.
When the timer returns to zero, the timer bell will ring
and microwave timer will operate automatically.
3.
Now, the oven is operating the microwave cooking,
4.
At the end of the microwave cook cycle, the timer bell
will ring and all components are de-energized.
