The PLC logged periodic high-alarm and open-wire diagnostic codes, causing false emergency shutdowns. Upon physical inspection, the technicians discovered that long 3-wire Pt100 cable runs were routed adjacent to a 480V VFD output cable, exceeding the module's 5-Ohm lead resistance threshold due to induced noise. By converting the sensor connection from 3-wire to a shielded 4-wire topology and re-grounding the carrier base shield bar, common-mode noise was completely suppressed.
