A detailed description isgiven for the following circuit functions:Analog Meter Readout Front Panel Controls Muffle Control Power Supply1.2.1 ANALOG METER READOUTThe Type K thermocouple which extends from the backof the muffle is directly connected to an analog meterwhich provides the operator with the present muffletemperature. This knowledge is necessary to aid in trou-bleshooting of a unit's failure and may also allow theuser to gain greater insight into the VULCANs versatilityfor particular applications. 8-13SECTION 1 - CIRCUIT DESCRIPTION - A-CONTROLThe purpose of this section is to familiarize the user orservice personnel with the circuit level operation of theVULCAN. 8-118.14 POWER SWITCH.8-128.15 POWER DOOR REPLACEMENT. A sawtooth signal from pin2 of U2 is comparedwith a fixed reference voltage which can be set by RP3.As the sawtooth voltage exceeds the value of the fixedreference voltage, amplifier U3 produces a negativeoutput which in turn increases the thermocouple signaloutput from U1 and Vpin3 of U2 and is now morenegative than Vref, thus the triac output pulses stop.1.2.4 POWER SUPPLYThe rectified supply current (D2) is zener regulated to8.6V and biased by dropping resistors R11, R12.The positive voltage to U1 and U2 is provided by a 6.8Vzener diode D1. Power is delivered by bursts tothe load.To slow down the heatup time of the muffle (RP2 setclockwise and muffle is at low temperature) a ratecontrol potentiometer (RP3) has been added to thecircuitry. As Vpin3 is near in value of Vref, a proportionalcontrol takes over, i. This muffletriac may be activated anytime when the AC cycle goesthrough zero, and once activated it will only be openedagain when the AC sine wave passes through 0volts.The triac is controlled by a Zero Voltage Switch(integrated circuit U2) and is configured as aproportional controller.Trigger pulses are generatedwhen the comparator detects Vpin3 is above the Vref.The sensed temperature from the amplifiedthermocouple signal is then lower than the set value ofRP2.
