Electrical power to be supplied to the oven by a three conductor service.
When the temperature in the control box reaches 120°F ± 3°F (48.9°C ± 1.7°C),
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°F (37.8°C ± 1.7°C).
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 fan through the EMI Filter to the primary of the control transformer, the
conveyor motor, and the burner system.
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.
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.
Closing the oven fan switch supplies 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 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.
