FULL SIZE ELECTRIC CONVECTION OVENS - ELECTRICAL OPERATION

1)Heating elements powered and heating starts.

C.The controls 5VDC output from pins

C2-2 (-) and C2-8 (+) is activated and SSR1 relay is energized.

1)Convection fan motor is energized (High speed).

4.Oven reaches set point temperature.

A.Computer control de-activates the output from pin C3-2.

1)2CON coil de-energized.

a.Power removed from heating elements and heating stops.

B.Oven "Heat Light" on the control goes out.

C.Oven "Ready Light" on the control comes ON.

D.Electronic beeper sounds momentarily.

5.The oven will continue to cycle on the computer control until the doors are opened or power switch (S1) is turned to the OFF or COOL DOWN position.

Temperature and Time Cycle (Cooking)

NOTE: The computers internal "Cook" timer operates independently of the heating cycle. Additional time can be set or the timer can be stopped and re-started throughout the cooking cycle.

Refer to the Instructions Manual for specific operating instructions of the oven Computer Control.

Cook and Hold Cycle

NOTE: For a detailed explanation of the "Cook & Hold" mode, refer to the Instructions Manual as outlined under "SETTING THE OVEN FOR COOK & HOLD" and "COOK & HOLD OPERATION".

In "Cook & Hold" mode, the operation of the computer control is identical to the normal Cook Cycle with these exceptions:

1.Oven "Cook & Hold" light on the control comes ON.

2.Convection fan will operate at Low speed, throughout the "Cook & Hold" cycle.

A.The computer control 5VDC output from pins C2-2 (-) and C2-8 (+) is de-activated and SSR1 relay is de-energized.

1)Power is removed from convection fan motor high speed terminal.

B.The computer control 5VDC output from pins C2-1 (-) and C2-8 (+) is activated and SSR2 relay is energized.

1)Power is applied to the convection fan motor low speed terminal.

3.At the end of the "Cook" time, the electronic beeper sounds momentarily to indicate the end of first stage cooking (oven operates normally at the temperature and time selected until time expires).

4.The display flashes HOLD as the oven enters HOLD mode. This is also considered second stage cooking (oven heating stops but product continues to cook on residual heat).

A.Convection fan motor is de-energized.

5.After the oven temperature drops below 150°F, the heat comes back ON and cycles as needed, to maintain the "Hold" temperature of 150°F.

A.Convection fan motor energized (Low speed).

6.The oven continues to cycle in this manner until one of the following occurs:

A.The "Cook & Hold" mode is turned OFF.

B.Power switch (S1) is turned to the OFF or COOL DOWN position.

Cool Down Cycle

1.Conditions.

A.Oven is ON.

B.Oven cavity temperature needs to be lowered.

C.Doors are open (door switch contacts OPEN).

D.Power switch (S1) set to either ON or OFF.

2.Power Switch (S1) turned to COOL DOWN.

A.Power is connected through power switch (S1) to the convection fan motor high speed terminal.

1)Convection fan motor energized (High speed).

3.The oven will continue to operate in COOL DOWN mode until the power switch (S1) is turned to the OFF or ON position.
