POWER SUPPLY 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. CONTROL BOX AUTO COOL DOWN

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°). 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 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. CONVEYOR DRIVE 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.

POWER SUPPLY Electrical power to be supplied to the oven by a three conductor service for

single phase and a four conductor service for three phase. Black conductor is hot. Red conductor is hot. Orange conductor is hot (used for three phase only). White conductor is neutral.

Green conductor is ground. CONTROL BOX AUTO COOL DOWN

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°). 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.

Centrifugal switch of main fan

motor

Check for 120VAC at wire #5 (input to centrifugal

switch, located at 6-pin connector in raceway near

the main fan motor) to neutral. If no voltage is

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,

oven cavity

Terminals are normally closed. If open, reset

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

present, and the motor is not running, check for

opens, shorts or grounds.

WITH POWER OFF: Turn motor to check for locked

rotor. Burner transformer Check for 120VAC supplied to the primary of the

burner transformer. If no voltage is present, trace

wiring back to the oven cavity hi-limit thermostat. If

voltage is present, check for 24VAC at transformer

secondary. If there is primary voltage but no

secondary voltage, replace burner transformer. Centrifugal switch of burner

blower motor

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

neutral. If voltage is not present, trace wiring back to

transformer. If voltage is present, check for voltage at

wire #14 to neutral. If no voltage is present at wire

#14, and motor is running, replace burner blower

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
