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 normally open 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 Conveyor 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 gearbox and the tach.

 

generator. The tach. generator is a DC voltage generator which supplies a voltage to

 

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

 

conveyor speed.

NOTE*

The 1200 Series Ovens utilize 2 complete conveyor drive systems.

TIME/TEMP DISPLAY

The Time/Temp Display is energized when the Fan Switch is closed, supplying 120

 

VAC to the primary of the12.6 volt Transformer. The secondary output of the

 

transformer, normally 13 to 14 VAC (depending on input), with a center tap is

 

supplied to terminals 1,2, and 3 of the Time/Temp Display. The center tap is terminal

 

2. The display works on a balanced input and center tap voltage to each leg must be

 

1/2 the total reading.

 

The speed side of the Time/Temp. Display uses a slotted disc (cemented to tach.

 

coupling) to break the infra-red light beam of the optical switch (mounted on gear

 

motor) producing electrical pulses that are transmitted to the display. The display

 

converts these pulses into a read-out of minutes and seconds.

 

The temperature portion of the display uses a Thermistor Probe to sense oven

 

temperature. The thermistor outputs a resistance proportional to the oven

 

temperature. This resistance is then converted by the display into a temperature

 

reading.

NOTE*

The 1200 Series Ovens use a Double Pole Double Throw Switch to connect the two

 

Optical Encoder Assemblies to the Time/Temp. Display. By activating the switch,

 

either the front or rear belt speed can be shown by the Time/Temp. Display.

SEQUENCE OF OPERATIONS 1040 / 1041 / 1240 / 1241

MODEL 1040 - 120/230 VAC - 60HZ - NATURAL GAS

MODEL 1041 - 120/230 VAC - 60HZ - L.P. GAS

MODEL 1240 - 120/230 VAC - 60HZ - NATURAL GAS/DUAL BELT

MODEL 1241 - 120/230 VAC - 60HZ - L.P. GAS/DUAL BELT

POWER SUPPLY

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

 

from the black conductor to the white conductor is 120 VAC.

 

Black conductor is Hot

 

Red conductor is Hot

 

White conductor is Dedicated Neutral

 

Green conductor is Ground

CONTROL BOX AUTO

When the temperature in the Control Box reaches 120°F ± 3°, the Cooling Fan

COOL DOWN

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 Main Fan

 

Switch, and the normally open Cool Down Thermostat (thermostat closes at 160°F

 

and opens at 140°F). Closing the Main Fan Switch energizes the coil of the Relay.

 

The normally open contacts now close, energizing the Main Fan Motor through two

 

10A fuses, and the Cooling Fan. Closing the Fan Switch also supplies power to the

 

12.6 VAC Transformer, the Burner and Conveyor Switches.
