1 PHASE 3240-2* 120/230VAC 60 HZ. 3 PHASE 3262-2* 120/230VAC 60 HZ. 1 PHASE 3262-2* 120/230VAC 60 HZ. 3 PHASE 3270-2* 120/230VAC 60 HZ. 1 PHASE 3270-2* 120/230VAC 60 HZ. 3 PHASE *NOTE: Model number ending in TS indicates top belt is split belt Model number ending in SB indicates bottom belt is split belt Model number ending in SS indicates both belts are split belts POWER SUPPLY Electrical power to be supplied to the oven by a four conductor service for single phase or a five conductor service for three phase. Black conductor is hot. Red conductor is hot. Orange conductor is hot. White conductor is neutral. Green conductor is ground. MAIN FAN CIRCUIT Power is permanently supplied to the normally open contacts of the main fan relay. Power is also supplied, through a 2 amp. fuse, to the 30 minute time delay relay. Closing the oven fan switch enables the 30 minute time delay relay. The 30 minute time delay relay supplies 120VAC to the coil of the main fan relay. These normally open contacts now close energizing the main fan motor. Closing the main fan switch also supplies 120VAC to the burner and conveyor switches. BURNER CIRCUIT Closing the main fan switch supplies 120VAC to the normally open burner switch. Closing the burner switch supplies 120VAC to the electronic temperature control, through the air pressure switch and the oven cavity hi-limit thermostat, to the normally open contact of the burner blower relay and to the primary of the burner transformer. The transformer’s secondary supplies 24VAC To the normally open contacts of the burner blower motor centrifugal switch and to the coil of the burner blower relay (the normally open contacts close within 30 seconds). The burner blower relay contacts close, supplying 120VAC to the burner blower motor. As the burner blower motor reaches operating speed, it’s internal centrifugal switch closes, supplying 24VAC to the burner control. When the burner control is supplied with 24VAC, the pilot valve is energized and the igniter circuit is energized. Ignition should now occur. After the pilot flame is proven, the main gas valve is energized. TEMPERATURE CONTROL Closing the main fan switch and burner switch supplies 120VAC to the electronic temperature control. The electronic temperature control is adjusted to the desired temperature. The thermocouple will provide varying millivolts to the electronic temperature control. The temperature control supplies 120VAC to the temperature regulation valve at intermittent intervals to maintain desired temperature. CONVEYOR DRIVE NOTE: THE OVEN WILL CONTAIN BETWEEN TWO AND FOUR SEPARATE CONVEYOR DRIVE SYSTEMS. THE SEQUENCE OF OPERATIONS WILL BE THE SAME FOR EACH MOTOR SYSTEM. Closing the main fan switch and the normally open conveyor switch supplies 120VAC, through a 2 Amp. fuse, to the conveyor control. AC voltage is converted to DC voltage and DC voltage is supplied, at terminals A+ and A-, to the conveyor motor. Adjusting the conveyor control will vary the DC output voltage. The speed of the motor will increase or decrease as the DC voltage from the conveyor control increases or decreases. The conveyor control uses a hall effect sensor and magnet, mounted on the conveyor motor that senses motor speed. Any change in motor load (± RPM) is detected by the sensor and the voltage to the motor is adjusted accordingly. AUTOMATIC COOL DOWN When the oven is started, the 30 minute time delay relay is enabled, permitting the oven fan to operate for approximately 30 minutes after the oven is shut off, to cool the oven. When the oven is shut off, the 30 minute time delay relay will keep the coil of the main fan relay closed for 30 minutes, maintaining operation of the main fan motor.
