3 PHASE POWER SUPPLY Electrical power is to be supplied to the oven by a five conductor service. Brown conductor is hot. Black conductor is hot. Black conductor is hot. Blue conductor is neutral. Green conductor is ground. CONTROL BOX AUTO When the temperature in the control box reaches 120°F ± 3°F (48.9°C COOL DOWN ± 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°C ± 1.7°C). MAIN FAN CIRCUIT Electrical power is permanently supplied through three 50 A fuses to the normally open contacts of the hi-limit contactor. Power is also supplied, through the 10 Amp motor and control fuse, through the normally closed control box hi-limit thermostat, to the normally open oven power switch. Power is also supplied to the control box cooling fan thermostat. Closing the oven power switch supplies line voltage to the main fan motor. Closing the oven power switch also supplies line voltage to the heat circuit and to the primary of the oven control transformer. HEAT CIRCUIT Closing the oven power switch supplies line voltage through the main fan air pressure switch, through the normally closed oven cavity hi-limit thermostat, to the oven control TEMPERATURE CONTROL Closing the oven power switch supplies line voltage, through the EMI filter, to the primary of the control transformer and through the air pressure switch and oven cavity hi-limit, to the oven control. 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 heat contactor at intermittent intervals to maintain desired temperature. The display on the oven control will indicate when the heat contactor is energized. NOTE: The display also indicates oven temperature. CONVEYOR DRIVE Closing the oven power 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 motor is not running, “BELT JAM” is indicated on the display.
