4. As the drum heats up further, relay K8 opens J10 Pin 1 to J10 Pin 5 and cycles off the inner element. The
heat system is now drawing 0 amps.
5. The drum temperature begins to drop and at that time the triac gate voltage, again, begins to pulsate 0
to 4.8 VDC.
6. The outer element is energized and draws approximately 7 amps. This outer element current begins to
climb slowly towards 11 amps.
7. At this point, relay K8 again closes J10 Pin 1 to J10 Pin 5, turns on the inner element, and the triac gate
voltage drops to 0 VDC and the outer element turns off. The inner element again draws approximately 12
amps.
8. This cycling pattern continues throughout the drying period.
