Power Levels; Upper Halogen Lamp Pair; Lower Halogen Lamp - GE SCB2000 Technical Service Manual

Power Levels

Advantium uses power from high-intensity halogen
lamps, as well as microwave energy, to cook foods
evenly and quickly (average of one-fourth the time
of a conventional oven) to seal in moisture and
flavor.
Power levels are selected with the selector dial
and can be adjusted before cooking or during
cooking. When using preset menu foods, the
power levels are already selected for you.
However, power levels can be adjusted when
cooking both preset menu food and when manual
cooking.
Power levels are adjusted independently for the
upper halogen lamps (pair), lower halogen lamp
(single), and microwave energy. When selecting
an upper halogen lamp power level, the power
level can only be selected for the pair. You can not
select power levels for the upper rear and upper
front independently.
Power levels of 0 to 10 can be selected for the
upper halogen lamps (pair), lower halogen lamp,
and microwave energy. The power levels control
the percentage of ON time for the upper halogen
lamp pair, the lower halogen lamp, and microwave
high voltage circuit.
The programming on the smart board which
controls the upper and lower halogen lamps, as
well as the high voltage/magnetron circuits,
operates on a duty cycle of 32 seconds. This
means the power level you select for each
component controls the percentage of ON time
during each 32-second period of time.
In the following example, the upper halogen lamps
would cycle for 80% of each 32-second period, the
lower would cycle at 50% of each 32-second
period, and the microwave high voltage circuit
would be energized for 30% of each 32-second
period.

Upper Halogen Lamp Pair (U=)
The upper halogen lamps provide radiant heat to
the top surface of the food. Select a higher setting
for thin foods requiring a golden brown top
(example: fish fillets, toast, boneless chicken
breasts). Select a lower setting for thicker foods
and foods with high sugar or fat content (example:
cakes, roasts).

Lower Halogen Lamp (L=)
The lower halogen lamp provides cooking from
below to heat the cooking surface (cooking trays
and cookware). Select a higher setting for thick or
dense foods that may not cook quickly in the
center (example: casseroles). Select a lower
setting for thin foods (example: cookies) and foods
containing high fat or sugar content (example:
pastries, cakes).
