motor and convection motor are turned on.
2. The coil of relay (RY4) is energized by the control unit.
The damper is moved to the closed position, closing the
damper switch contacts. The closing of the damper
switch contacts sends a signal to the LSI on the control
unit de-energizing the relay (RY4) and opening the circuit
to the damper motor.
3. The solid-state relays are energized by the control unit
and the main supply voltage is applied to the top and side
heating elements.
4. When the oven temperature reaches the selected preheat
temperature, the following operations occur:
4-1 The solid-state relays are de-energized by the control
unit temperature circuit and thermistor, opening the
circuit to the heating elements.
4-2. The oven will continue to function for 30 minutes,
turning the heating elements on and off, as needed
to maintain the selected preheat temperature. The
oven will shutdown completely after 30 minutes
CONVECTION COOKING CONDITION
Touch the CONVECTION pad first and then touch the
Temperature pad. And program desired cooking time by
touching the Number pads. When the START pad is touched,
the following operations occur:
(Figure O-3)
1. The numbers on the digital read-out start to count down
to zero.
2. The oven lamp, turntable motor, cooling fan motor and
convection motor are energized.
3. The damper is moved to the closed position.
4. The solid-state relays are energized (if the cavity
temperature is lower than the selected temperature) and
the main supply voltage is applied to the heating elements
to return to the selected cooking temperature.
5. Upon completion of the cooking time, the audible signal will
sound, and oven lamp, turntable motor, cooling fan motor
and convection motor are de-energized. At the end of the
convection cycle, if the cavity air temperature is above
230
ο
F, the circuit to RY5 will be maintained (by the
thermistor circuit) to continue operation of the cooling fan
motor until the temperature drops below 195
ο
F, at which
time the relay will be de-energized, turning off the fan
motor. Relay RY3 will however, open as soon as the
convection cycle has ended, turning off the convection fan
motor.
6. At the end of the convection cook cycle, if the cavity air
temperature is below 250
ο
F, shut-off relay (RY4) is
energized turning on the damper motor. The damper is
returned to the open position, closing the damper switch
contacts which send a signal to the control unit, de-
energizing shut-off relay (RY4).
NOTE: When "Preheat" and "Convection" is
programmed continuously, after preheat, the
heating elements operate as follows.
When one of 100
ο
F to 375
ο
F is selected, for the
first 1 minute, the top and side heating elements
are not energized. When one of 400
ο
F to 450
ο
F
is selected, for the first 2 minutes, the top and
side heating elements are not energized.
SPEED BAKE COOKING
Touch the BAKE pad and then enter cooking time. When the
start pad is touched, following operations occur;
(Figure O-3)
1. The contacts of the relays RY1, RY3 and RY5 are
closed, and the oven lamp, turntable motor, convection
motor and fan motors are energized.
NOTE : The rotate direction of the convection motor is
the same as one of the convection cooking.
2. The damper is moved to the closed position.
3. The solid-state relays are energized and the main supply
voltage is applied to the top and side heating elements.
NOTE : After cooking, the operation of the fan motors,
damper motor is the same as one of the
convection cooking.
SPEED GRILL COOKING
Touch the GRILL pad and then enter cooking time. When
the start pad is touched, following operations occur;
(Figure O-4)
1. The contacts of the relays RY1, RY3, RY5 and RY6 are
closed, and the oven lamp, turntable motor, convection
motor and fan motors are energized.
NOTE : The rotate direction of the convection motor is
reverse to one of the convection cooking by the
relay RY6.
2. The damper is moved to the closed position.
3. The solid-state relays are energized and the main supply
voltage is applied to the top and side heating elements.
NOTE : After cooking, the operation of the fan motors,
damper motor is the same as one of the
convection cooking.
SPEED ROAST COOKING
Touch the ROAST pad and then enter cooking time. When
the start pad is touched, following operations occur;
(Figure O-5)
1. The contacts of the relays RY1, RY3 and RY5 are
closed, and the oven lamp, turntable motor, convection
motor and fan motors are energized.
NOTE : The rotate direction of the convection motor is
the same as one of the convection cooking for
the first time. But for the last 15 minutes, the
direction is reverse by the relay RY6.
2. The damper is moved to the closed position.
3. The solid-state relays and relay RY2 are energized
alternately, and the main supply voltage is applied to the
top and side heating elements and the power transformer
alternately.
NOTE : After cooking, the operation of the fan motors,
damper motor is the same as one of the
convection cooking.
SPEED COOKING OF AUTOMATIC COOKING
(BASIC COOK, RECIPES)
Speed cooking of Automatic cooking will automatically
compute the oven temperature, microwave power and
cooking time. And the oven will cook according to the special
cooking sequence.
MICROWAVE OPTIONS OF AUTOMATIC COOK-
ING
(REHEAT, POPCORN, COOK, DEFROST)
Microwave options of Automatic cooking will automatically
compute the microwave power, cooking time or defrosting
