Electrical power is supplied to the oven by a three-conductor cordset. Voltage from the black conductor to the white conductor is 120VAC.

Black conductor is hot White conductor is neutral. Green conductor is ground.

When the temperature in the control box reaches 120°F ± 3° (48.9°C ± 1.7°), 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° (37.8°C ± 1.7°).

Power is permanently supplied, through a 10 amp fuse, and through a normally closed control box hi-limit thermostat, to the normally open main power switch. Power is also supplied to the normally open cooling fan thermostat. Closing the main power switch supplies 120VAC to the main fan motor, the cooling fan motor, the primary of the control transformer, the conveyor motor and to the ignition control.

Closing the main power switch supplies 120VAC to the burner blower motor. 120VAC is also supplied, through the normally closed oven cavity hi-limit thermostat, the main fan centrifugal switch (this switch closes when the main fan reaches approx. 1600 RPM), to the primary of the burner transformer.

The ignition control operates on both 24VAC and 120VAC. When the control is energized by 24VAC from the transformer, 120VAC is switched by the ignition control to the hot surface igniter for 45 seconds for the hot surface igniter warm up. The igniter glows red, 24VAC is switched to the gas valve, which opens, and ignition should now occur.

Closing the main power switch supplies 120VAC to the primary of the oven control transformer. Secondary voltage, 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 120VAC to the temperature regulation valve at intermittent intervals to maintain the desired temperature. The display on the oven control will indicate when the temperature regulation valve is energized.

NOTE: The display also indicates oven temperature

Closing the main power switch supplies 120VAC 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 hall effect sensor and magnet to prove operation of the conveyor motor. If the conveyor motor is not running, “BELT JAM” is indicated on the display.
