AH SENSOR COOKING SEQUENCE
1. When the AH sensor cooking condition is started, the
coil of shut-off relays (RY1+RY6) are energized, the
oven lamp and cooling fan motor are turned on, but the
power transformer is not turned on.
NOTE: The oven should not be operated on AH SENSOR
COOKING immediately after plugging in the unit.
Wait two minutes before cooking on AH SENSOR
COOKING CONDITION.
2. After about 16 seconds, the cook relay (RY2) is ener-
gized. The power transformer is turned on, microwave
energy is produced and first stage is started. The 16
seconds is the cooling time required to remove any
vapour from the oven cavity and sensor. (Figure O-2)
NOTE: During this first stage, do not open the door or
touch STOP/CLEAR pad.
3. When the sensor detects the vapour emitted from the
food, the display switches over to the remaining cooking
time and the timer counts down to zero.
At this time, the door may be opened to stir food, turn it
or season, etc.
NOTE: In case where a small quantity of food is cooked,
the oven will stop without displaying the remaining
cooking time.
4. When the timer reaches zero, an audible signal sounds.
The shut-off relay (RY1+RY6) and cook relay (RY2)
are de-energized and the power transformer, oven
lamp, etc. are turned off.
5. Operating the door or touching the STOP/CLEAR pad,
the time of day will reappears on the display and the
oven will revert to an OFF condition.
