POWER SUPPLY

Electrical power to be supplied to the oven by a five conductor service.

 

Brown conductor is hot.

 

 

 

Black conductor is hot.

 

 

 

Black conductor is hot.

 

 

 

Blue conductor is neutral.

 

 

 

Green conductor is ground.

 

 

CONTROL BOX

When the temperature in either one of the control boxes reaches 120°F ±3° (49°C ±

AUTO COOL DOWN

°

 

 

 

1.7 ), the cooling fan thermostats will switch power to the cooling fans. The thermostats

 

will interrupt power to the cooling fans when the temperature falls to 100°F ± 3° (37°C ±

 

1.7°)

 

 

MAIN FAN CIRCUIT

Line voltage is permanently supplied (through a power filter) to a normally open contact of

 

the oven power switch. Line voltage is permanently supplied to the two normally open

 

cooling fan thermostats. Closing the oven power switch supplies line voltage, through both

 

normally closed control box hi-limit thermostats, to the oven power relay. Its contacts now

 

close supplying line voltage to the two main fan motors. Closing the oven power switch also

 

supplies line voltage to the control box cooling fans, the oven control, the control

 

transformer, and the conveyor motor.

 

TEMPERATURE

Closing the oven power switch supplies line voltage, through the 10 amp. fuse, through the

CONTROL

oven power relay, to the primary of the control transformer. 24VAC is supplied to the oven

 

control. The oven control is set to desired temperature. The thermocouple will provide

 

varying millivolts to the oven control. The oven control supplies line voltage to the contactor

 

at intermittent intervals to maintain desired temperature. The display on the oven control

 

will indicate when the contactor is energized.

 

 

NOTE: The display also indicates oven temperature.

CONVEYOR DRIVE

Closing the oven power switch supplies line voltage, through the 10 Amp fuse, through the

 

oven power relay to the conveyor motor and to the primary of the control transformer.

 

Secondary voltage, 24VAC, is supplied to the oven control. Setting the oven control to the

 

desired time, outputs voltage, through a reversing switch, to the conveyor motor

 

NOTE: The conveyor system uses a magnet and hall effect sensor to prove operation of

 

the conveyor motor. If the conveyor motor is not running, “BELT JAM” is indicated on the

 

display.

 

 

AUTOMATIC COOL

When the oven is started, the time delay relay timing circuit is enabled, permitting the oven

DOWN

fans to operate for approximately 20 minutes after the oven is shut off, to cool the oven.

 

The time delay relay will keep the coil of the motor relay closed, maintaining operation of

 

main fan and cooling motors.
