SEQUENCE OF OPERATIONS 1002/1003

 

MODEL 1002 - 240VAC - 50HZ - NATURAL GAS

 

MODEL 1003 - 240VAC - 50HZ - L.P. GAS

 

 

 

POWER SUPPLY

 

Electrical Power to be supplied to the Oven by a three conductor service.

 

 

Black conductor is Hot

 

 

Red conductor is Neutral

 

 

Green conductor is Ground

CONTROL BOX

 

When the temperature in the Control Box reaches 120°F +

AUTO COOL DOWN

 

3°, the Cooling Fan Thermostat will switch power to the Control Box Cooling Fan.

 

 

The Thermostat will interrupt power to the Cooling Fan when the Control Box

 

 

temperature falls to 100°F + 3°.

MAIN FAN CIRCUIT

 

Electrical power is permanently supplied to the normally open contacts of the Double

 

 

Pole Main Fan Relay, the Cooling Fan Thermostat, the normally open Double Pole

 

 

Main Fan Switch, and the normally open Cool Down Thermostat (thermostat closes

 

 

at 160°F and opens at140°F). Closing the Main Fan Switch supplies 240 VAC

 

 

through a 3A Fuse to the primary of the control circuit Step down Transformer. The

 

 

Transformer steps the voltage down to 120 VAC for the control circuit. 120 VAC is

 

 

supplied to the coil of the Double Pole Main Fan Relay. The coil of the relay is

 

 

energized. The normally open contacts now close, energizing the Main Fan Motor

 

 

through one 10A Fuse. Closing the Fan Switch also supplies power to the Cooling

 

 

Fan, Hour Meter (hour meter discontinued after S/N 3484), the 12.6 VAC

 

 

Transformer, the Burner and Conveyor Switches.

BURNER CIRCUIT

 

Closing the Fan Switch and the normally open Burner Switch supplies 120 VAC

 

 

through the Air Pressure Switch, to the normally open contacts of the Burner Motor

 

 

Relay, and the primary of the 24 VAC Step Down Transformer. The Transformer

 

 

secondary supplies 24 VAC to the Relay Coil (the normally open contacts close

 

 

within 30 seconds), and the normally open Centrifugal Switch. When the Relay

 

 

contacts close, the Burner Blower Motor is energized. As this motor reaches

 

 

approximately 1600 R.P.M., its internal centrifugal switch closes, supplying 24 VAC

 

 

to the Gas Control Valve. When the Gas Control Valve is supplied with 24 VAC, the

 

 

pilot valve is energized, and the igniter circuit is energized. Ignition should now

 

 

occur. After pilot flame is proven, the main gas valve is energized. The Burner

 

 

Indicator Light is also energized.

CONVEYOR DRIVE

 

Closing the Fan Switch and the normally open Conveyor Switch supplies 120 VAC

(S/N 100 to 4389)

 

through a 3A Fuse, to the Motor Control Board. AC volts are converted to D.C. volts

 

 

and are supplied to the Conveyor Motor at board terminals A1 and A2 through a

 

 

D.P.D.T. Reversing Switch. Adjustment of the Speed Control Potentiometer (500

 

 

ohm, 10 turn) will change resistance at terminals S1, S2, and S3 varying the D.C.

 

 

voltage to the motor. The speed of the Conveyor Motor will increase or decrease as

 

 

the D.C. voltage from the Motor Control Board increases or decreases respectively

(S/N 4390 and UP)

 

Closing the fan switch and the conveyor switch supplies 120 VAC to the Motor

 

 

Control Board. AC volts are converted to DC volts and are supplied to the Conveyor

 

 

Motor at terminals A+ and A-. Adjustment of the Speed Control Potentiometer (5,000

 

 

ohm 10 turn) will change resistance at terminals P1, P2, and P3 varying the DC

 

 

voltage to the motor. The speed of the conveyor motor will increase or decrease as

 

 

the DC voltage from the board increases or decreases respectively. As the motor

 

 

turns, it drives both the reducer gear box and the tach. generator which supplies a

 

 

voltage to the DC motor control board and is used as a reference for maintaining a

 

 

constant conveyor speed
