POWER SUPPLY Electrical power is supplied to the oven by a three-conductor cord set.
Voltage from the black conductor to the white conductor is 120VAC.
Black conductor is hot.
White conductor is neutral.
Green conductor is ground.
CONTROL BOX AUTO
COOL DOWN
When the temperature in the control boxes reaches 120°F ±3° (49°C ± 1.7°), the cooling fan thermostat
will switch power to the cooling fans. The thermostat will interrupt power to the cooling fans when the
temperature falls to 100°F ± 3° (37°C ± 1.7°).
MAIN FAN CIRCUIT Power is permanently supplied, through a 10 amp fuse, 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 motors, the primary of the control transformer, the conveyor motor
and to the ignition control.
BURNER CIRCUIT Closing the main power switch supplies 120VAC to the burner blower motor. 120VAC is also supplied,
through the main fan centrifugal switch (this switch closes when the main fan reaches approx. 1600 RPM)
and the normally closed oven cavity hi-limit thermostat, to the primary of the burner transformer. 120VAC is
also supplied to the oven control.
IGNITION CONTROL 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.
TEMPERATURE CONTROL Closing the oven power switch supplies line voltage, through the 10A fuse, through the 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 right thermocouples will provide varying millivolts to the oven control. The
oven control supplies line voltage to the temperature regulation valve at intermittent intervals to maintain
desired temperature. The display on the oven control will indicate when the temperature regulation valve is
energized. NOTE: The display also indicates oven temperature of the oven.
CONVEYOR DRIVE Closing the oven power switch supplies line voltage, through the 10A 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.

will switch power to the cooling fans. The thermostat will interrupt power to the cooling fans when the
temperature falls to 100°F ± 3° (37°C ± 1.7°).
MAIN FAN CIRCUIT Power is permanently supplied through a 10 amp oven fuse to the normally open double pole oven fan
switch. Closing the oven fan switch supplies line voltage to the main fan motor. Closing the main fan switch
also supplies voltage to the cooling fans and the EMI Filter to the primary of the control transformer, the
conveyor motor, and the burner system.
BURNER CIRCUIT Closing the oven fan switch supplies line voltage through the normally open air pressure switch (closed by
the air pressure from the main fan), through the normally closed oven cavity hi-limit thermostat (opens at
662°F, 350°C), and to the ignition control.
IGNITION CONTROL The ignition control switches line voltage to the combustion blower motor. The combustion air pressure
switch switches from normally closed to normally open upon sensing air pressure in the burner housing.
After a pre-purge period of between 30 and 60 seconds, the spark is energized, the main gas valve and the
burner pilot light are energized, and ignition should now occur.
TEMPERATURE CONTROL When the power supply is passed through the EMI Filter the load will supply line voltage 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 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

temperature falls to 100°F ± 3° (37°C ± 1.7°).
MAIN FAN CIRCUIT Power is permanently supplied through the 10 amp fuses, through the normally closed oven cavity 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 energizes the coil of the oven start relay, it’s contacts close
enabling the 20 minute time delay relay. The 20 minute time delay relay supplies 120VAC to the oven fan
relay, these normally open contacts now close supplying 208/240VAC to the main fan motor. 120VAC is also
supplied to the cooling fans. 208/240VAC is supplied to the primary of the control transformer, the conveyor
motor and, through the air pressure switch, to the oven control.
TEMPERATURE CONTROL Closing the main power switch supplies 208/240VAC 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 208/240VAC to
the coil of the heater relay at intermittent intervals to maintain the desired temperature. The display on the
oven control will indicate when the heater relay is energized.
NOTE: The display also indicates oven temperature.
CONVEYOR DRIVE Closing the main power switch supplies 208/240VAC 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.
AUTOMATIC COOL DOWN When the oven is started, the time delay relay timing circuit is enabled, permitting the oven fans to run
approximately 20 minutes after the oven is shut off, to cool the oven. The time delay relay will keep the coil
of the fan relay closed, maintaining operation of the main fan and cooling fans.
