POWER SUPPLY
Electrical power is supplied to the oven by either a single phase, 3 conductor service, or three phase, 4 conductor service.
Single:
Black conductor is hot. White conductor is hot. The green conductor is ground.
Three Phase:
Black conductor is hot. Red conductor is hot. Orange conductor is hot. The green conductor is ground.
FAN CIRCUIT
Electrical power is permanently supplied to the normally open contacts of the main power relay, the main switch 1 A fuse, terminal 1 of the time delay unit, also through the normally closed hi limit thermostat, to the main power switch. Closing the main switch enables the 30 minute timer delay relay. The time delay relay supplies line voltage to the cooling fan motor.
INFRARED HEAT
Closing the main switch supplies line voltage to the coil of the main power relay, closing the contacts to feed the normally open solid state relays for the top and bottom heaters. Power also feeds the primary of the transformer, secondary 16V feeds through a circuit breaker to the control unit. The control energizes the solid state relays for the top and bottom heaters feeding voltage to the heating elements.
TEMPERATRE CONTROL Closing the main switch supplies line voltage to the primary of the control
transformer, secondary 16vac is supplied to the control unit which is set to a desired temperature. The thermocouple will provide varying millivolts to the control unit. The control unit supplies voltage to the coil of the heater relays at intermittent intervals, to maintain a desired temperature. The display on the control unit will signal when the main heater relay is energized. NOTE: The control unit will also display oven temperature.
CONVEYOR DRIVE
Closing the main switch supplies line voltage to the primary of the control transformer, secondary 16vac is supplied to the control unit. Setting the control unit to the desired time, outputs voltages to the conveyor motor.
AUTOMATIC COOL DOWN
When the machine is started, the time delay unit is energized, permitting the main fan to operate for approximately 30 minutes after the machine is shut off, to cool the machine. When the machine is turned off the time delay unit keeps the main fan energized, maintaining operation of the fan for 30 minutes.

Check power cord to ensure it is plugged into receptacle. Check circuit breakers. Reset if required. Call power company if needed.
Check and replace if necessary.
Check power cord to ensure it is plugged into receptacle. Check circuit breakers. Reset if required. Call power company if needed.
Check and replace if necessary.
Check for voltage on both sides of thermostat. Terminals are normally closed. If open, wait for oven to cool down. Once oven has cooled, contacts should go back to normally closed position. If thermostat does not return to normally closed or will not hold, replace.
Check for main power to the primary side of the control transformer. If no voltage is present, trace wiring back to main power switch. Check for secondary voltage off of the transformer 16~26VAC. If there is no secondary voltage off of transformer then replace transformer.
Check that the switch pad is plugged into the controller. Ensure all electrical connections are tight.
Check for supply voltage to control (16~26 VAC). If no voltage is present, trace wiring back to transformer. If control voltage is present, check display to see that information is displayed on the screen. If nothing is displayed on screen, replace controller. If there is a read-out on the controller, set the temperature to the maximum setting (see operations manual). With the control at the maximum setting, check for output voltage (5 VDC) to the solid state relays. If there is a 5 VDC signal to the solid state relays, proceed to “solid state relays” for more troubleshooting information. If
