Logixpro Dual Compressor Exercise 2 Site

That Tuesday, the thermometer on the mezzanine read 104°F. Titan’s cooling fan seized at 2:17 PM. By 2:22, its discharge temperature alarm screamed red on the control panel. The compressor didn't stop—it just kept churning, heating the air to 190°F, expanding it like a furious ghost. The pressure at the receiver tank began to drop.

In the LogixPro simulation, you had ladder logic timers: T4:0 for the “minimum run time” and T4:1 for the “anti-cycle delay.” Maria had no time to program. She had to become the PLC. logixpro dual compressor exercise 2

“Atlas, you’re up,” she whispered, hammering the HMI start button. That Tuesday, the thermometer on the mezzanine read 104°F

She sprinted to the MCC (Motor Control Center) and yanked the disconnect for Titan. The massive screw element ground to a halt with a mournful groan. The plant pressure gauge needle wobbled at 92 PSI and began to fall. The compressor didn't stop—it just kept churning, heating

Maria’s mind flashed to the exercise rubric: “When a compressor faults, the alternate must take over within 2 seconds. Pressure must not fall below 80 PSI.”
