The temperature portion of the Time/Temp Display uses a Thermistor Probe to sense oven temperature. The thermistor outputs a resistance proportional to the oven temperature. This resistance is then converted by the display into a temperature reading. AUTOMATIC COOL DOWN When the oven reaches operating temperature the normally open Oven Cool Down Thermostat closes. After the oven is switched OFF, the Ther mostat bypasses the Fan Switch, keeping the Cooling Fan and Main Fan in operation until the

adjusted to desired temperature. The Thermocouple will provide varying millivolts to the Electronic Temperature Controller. The electronic tempera- ture controller supplies 120 VAC to the Solenoid Valve at intermittent intervals to maintain desired temperature. CONVEYOR DRIVE Closing the Conveyor Switch supplies 120 VAC to the D.C. Motor Control Board at terminals L1 and L2. AC volts are converted to DC volts and are supplied to the Conveyor Motor at terminals A+ and A- . Adjustment of the

NOTE: The Conveyor Control uses a sensor and magnet, mounted on the Conveyor Motor that senses when the motor is not turning. If the motor is not turning, the Time/Temp Display will show : in the window. The temperature portion of the display uses a Thermistor Probe to sense oven temperature. The Thermistor outputs a resistance proportional to oven temperature. This resistance is then converted by the Display into a temperature reading. OR: The temperature potion of the display uses a J
