	The speed side of the Time/Temp. Display uses a slotted disc
	(cemented to tach. coupling) to break the infra-red light beam
2011383 and above	of the optical encoder(mounted on gear motor),
Refer to Page B15	producing electrical pulses that are transmitted to the display. The display
	converts these pulses into a read-out of minutes and seconds. 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 this oven is started, the time delay relay timing circuit is enabled,
	permitting the oven fans to run for approximately 20 minutes after the oven
	is shut off, to cool the oven. The Time Delay Relay will keep the coil of
	Relay closed maintaining operation of the Main Fan Motor and cooling
	fans.
