MAIN FAN CIRCUIT
Power is permanently supplied, through the 10 amp oven fuse, through the
normally closed control box hi-limit thermostat (opens at 140
normally closed control box hi-limit thermostat (opens at 140
°F, 60°C), to the
normally open oven fan switch. Power is also supplied to the normally open
cooling fan thermostat. Closing the oven fan switch supplies line voltage to the
main fan motor, the cooling fan, the primary of the control transformer and to
the oven control.
cooling fan thermostat. Closing the oven fan switch supplies line voltage to the
main fan motor, the cooling fan, the primary of the control transformer and to
the oven control.
HEAT CIRCUIT
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.

CONVEYOR CONTROL
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.
