CONVEYOR DRIVE

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 fans. The thermostat will interrupt power to the cooling fans when the control box temperature falls to 100°F ± 3° (37.8°C ± 1.7°).

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.

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.

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.

CONTROL BOX AUTO

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

 

COOL DOWN

cooling fan thermostat will switch power to the control box cooling fans. The

 

 

thermostat will interrupt power to the cooling fans when the control box

 

 

temperature falls to 100°F ± 3° (37.8°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.

present, trace wiring back to the main power switch.

 

 

If voltage is present, check for 120VAC at wire #22

 

 

(output of centrifugal switch) to neutral. If no voltage

 

 

is present at #22, and the motor is running, replace

 

 

the main fan motor.

 

Hi-limit thermostat,

Terminals are normally closed. If open, reset

 

oven cavity

thermostat and retest. If thermostat will not hold for

 

 

maximum oven temperature, and oven is not

 

 

exceeding temperature setting, check for proper

 

 

location of capillary bulb in its spring holder. If the

 

 

capillary checks okay, replace the hi-limit thermostat.

 

Burner blower motor

Check for 120VAC supplied to burner blower motor

 

 

at wire #13 to neutral. If no voltage is present, trace

 

 

wiring back to the main power switch. If voltage is

rotor.

 

Burner transformer

Check for 120VAC supplied to the primary of the

 

 

burner transformer. If no voltage is present, trace

secondary. If there is primary voltage but no

 

 

secondary voltage, replace burner transformer.

 

Centrifugal switch of burner

Check for 24VAC at motor connector, wire #13 to

motor.

 

Ignition control

Check for 24VAC at ignition control terminals marked

 

 

“24V”, if no voltage is present, trace wiring back to

 

 

centrifugal switch. Check for 120VAC to ignition

 

 

control at terminal “L1” to neutral. If no voltage is

 

 

present, trace wiring back to main power switch.

 

 

When 24VAC is supplied to the ignition control, the

 

 

ignition control switches 120VAC to the hot surface

 

 

igniter If 24VAC and 120VAC are supplied to ignition

 

 

control, but there is no voltage at the hot surface

 

 

igniter, replace the ignition control.

 

Hot surface igniter

If 120VAC is present at hot surface igniter terminals,

 

 

visually check to see that the igniter is heating

 

 

(igniter may be viewed through the port in the end of

 

 

burner tube). The igniter should glow bright red. If the

 

 

igniter does not heat, replace the hot surface igniter.

 

Ignition control

After 45 seconds of hot surface igniter pre-heat, the

 

 

ignition control will switch 24VAC to the gas control

 

 

valves. Check for 24VAC output from ignition control

 

 

across terminals marked “valve” and “valve gnd”. If

 

 

no voltage is present, replace ignition control.

 

Gas control valves

When 24VAC is supplied to the gas control valves,

 

 

the valve should open. Check for gas pressure at the

 

 

manifold tap located just before the burner. If there is

 

 

no pressure, check the incoming gas supply to be

 

 

sure all manual valves are open and flexible gas

 

 

hose is properly connected. If gas is present, and the

 

 

gas control valve is energized, but there is no gas

 

 

pressure at the burner manifold, replace the gas

 

 

control valves.
