Atlas roared to life. Pressure stabilized at 96 PSI. For thirty seconds, Maria breathed. Then the production line kicked into high gear—three cappers firing at once, a purge cycle on the filler, and a labeler changeover. The pressure cratered to 85 PSI.
At 2:30, Maria Chen, the shift electrician, pulled up the LogixPro simulation on her laptop—the training software she’d mastered years ago. But this wasn’t a classroom exercise. This was Exercise 2 for real. logixpro dual compressor exercise 2
She jumped to the control cabinet, fingers flying over the old Allen-Bradley pushbuttons. She disabled the automatic lead-lag and forced Atlas into continuous run. Then she saw the problem: Atlas’s unloader solenoid was sticky. The compressor was starting under full load, drawing 300% amperage. The thermal overload relay clicked once, twice—on the third click, it would trip. Atlas roared to life
Maria stared at the LogixPro window still open on her laptop. The virtual pressure gauge was steady at 95 PSI. The virtual “Dual Compressor Exercise 2” completion banner flashed green. Then the production line kicked into high gear—three
In LogixPro’s “Dual Compressor Exercise 2,” the goal was simple: maintain 90–100 PSI with two compressors, handle duty cycling, and prevent both from running simultaneously for too long to avoid overload. The twist? A random “fault” could disable one compressor, forcing the other to handle the load within strict time limits.
