Electrical power to be supplied to the oven by a four conductor service. Brown conductor is hot.
Black conductor is hot. Black conductor is hot. Green conductor is ground.
Power is permanently supplied, through the 10 amp oven fuse, through the normally closed control box
Closing the oven fan switch supplies line voltage, through the normally open air pressure switch (closed by air pressure from the main fan) to the oven control. Line voltage is also supplied to the primary of the 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 line voltage to the coil of the contactor at intermittent intervals to maintain the desired temperature. The display on the oven control will indicate when the contactor is energized.
NOTE: The display also indicates oven temperature.
Closing the oven fan switch supplies line voltage 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.
