THEORY OF OPERATION 9
Keypad
The primary interface for the operator.
Display
Displays all visual information to the operator.
Self-Test (STEST)
A special diagnostic function that tests all critical subsystems to determine their operational state.
Recipe
A set of user-defined Events that determine a cook cycle.
Events
A single operational element that is a part of a recipe. Each recipe may have up to six events depending on
programming. Each event can be set between 0 and 100% of the total cook time.
Total Cook Time
The total duration of a recipe.
Percentage (%) Time
An event subset that specifies the duration of the event. The sum of all event time percentages for a recipe
must equal 100%.
Percentage (%) Air
An event subset that specifies the relative amount of impingement airflow (speed of convection motor) dur-
ing an event. Valid between 10 and 100%.
N O T E
: Maximum 100% = 7100 RPM blower motor speed. Blower motor speed scale is linear.
Percentage (%) Microwave (WAV)
An event subset specifying the microwave cycle during the event. Valid between 0 and 100%. For example,
if WAV is set to 30%, then microwave would be present in the cook cycle for 3 out of every 10 seconds.
Fault Code
A code assigned to an instance that the control considers to be a failure. Upon discovering a fault, the
control will display the fault code and a brief description of the failure. The oven will also log faults F1
through F6 in the Fault Log. See page 11 for more detail on faults and for viewing the fault log.
