Electrolux EI30BM55HB - 30" Microwave Oven, Техническое и сервисное руководство

Страница: 15 / 60

An example of how the sensor works:
(BAKED POTATOES)
1. Potatoes at room temperature. Vapor is emitted
very slowly.
2. Heat Potatoes. Moisture and humidity is emitted
rapidly. You can smell the aroma as it cooks.
3. Sensor detects moisture and humidity and
calculates cooking time and variable power.
Cooking Sequence.
1. Operate the oven in sensor cooking mode by
referring to the operation manual.
NOTE: The oven should not be operated on SENSOR
immediately after plugging in the unit. Wait two
minutes before cooking on SENSOR.
2. The coil of shut-off relays (RY1 and RY3) are
energized, the oven lamp, turntable motor and
cooling fan motor are turned on, but the power
transformer is not turned on.
3. After about 32 seconds, the cook relay (RY-2) is
energized. The power transformer is turned on,
microwave energy is produced and first stage is
started. The 32 seconds is the cooling time
required to remove any vapor from the oven
cavity and sensor.
NOTE: During this first stage, do not open the door or
touch STOP/CLEAR pad.

VARIABLE COOKING
When Variable Cooking Power is programmed, the
120 volts A.C. is supplied to the power transformer
intermittently through the contacts of relay (RY2)
which is operated by the control unit within an
interval second time base. Microwave power
operation is as follows:
Vari-Mode ON TIME OFF TIME
Power 10 (High) (100% Power) 32 sec. 0 sec.
Power9(P-90) (Approx. 90%) 30 sec. 2 sec.
Power8(P-80) (Approx. 80%) 26 sec. 6 sec.
Power7(P-70) (Approx. 70%) 24 sec. 8 sec.
Power6(P-60) (Approx. 60%) 22 sec. 10 sec.
Power5(P-50) (Approx. 50%) 18 sec. 14 sec.
Power4(P-40) (Approx. 40%) 16 sec. 16 sec.
Power3(P-30) (Approx. 30%) 12 sec. 20 sec.
Power2(P-20) (Approx. 20%) 8 sec. 24 sec.
Power1(P-10) (Approx. 10%r) 6 sec. 26 sec.
Power0(P-0) (0% power) 0 sec. 32 sec.
NOTE: The ON/OFF time ratio does not correspond
with the percentage of microwave power, because
approx. 2 seconds are needed for heating of the mag-
netron filament.
POWER OUTPUT REDUCTION
If the oven is set for over 40 minutes at 80%, 90% or
100% power level, after the first 40 minutes the power
level will automatically adjust itself to 70% power to
avoid overcooking.
SENSOR COOKING CONDITION
Using the Sensor cooking function the food is cooked
without figuring time, power level or quantity. When
the oven senses enough steam from the food, it
relays the information to its microprocessor which will
calculate the remaining cooking time and power level
needed for best results. When the food is cooked,
water vapor is developed. The sensor
“senses” the vapor and its resistance increases
gradually. When the resistance reaches the value set
according to the menu, supplementary cooking is
started. The time of supplementary cooking is
determined by experiment with each food category
and input into the LSI.
