FULL SIZE GAS CONVECTION OVENS - ELECTRICAL OPERATION

3.Oven reaches set point temperature.

A.Computer control de-activates the 120VAC output to heat relay (R1).

1)Heat relay (R1) de-energized and the normally open (N.O.) contacts OPEN.

a.Power removed from ignition control module.

a)The 2nd valve (main) on the gas valve is de-energized and gas flow to the burner stops.

B.Oven HEAT LIGHT on the control goes out.

C.Oven READY LIGHT on the control comes ON.

D.Electronic beeper sounds momentarily.

4.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 OVEN COOL 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 Owners's Manual for specific operating instructions of the oven Computer Control.

Roast and Hold Cycle

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

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

1.Oven ROAST & HOLD light on the control comes ON.

2.Convection fan speed changes from High to Low.

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

1)Power (120VAC) 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 (120VAC) is applied to the convection fan motor low speed terminal.

3.At the end of the ROAST 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.

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

A.The ROAST & HOLD mode is turned OFF.

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

Oven Cool Cycle (Computer Control Model)

1.Conditions.

A.Oven is ON.

B.Oven cavity temperature needs to be lowered.

C.Doors are open.

1)Door switch contacts OPEN.

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

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

NOTE: With door switch contacts OPEN (doors open), the convection fan motor will still run and continue to cool the oven.

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

1)Convection fan motor energized.

2)When Convection fan motor reaches operating speed the centrifugal switch on the motor closes but no power is available for connection to other components.

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