You start on the production floor, scanning HMIs for alarms, trending VFD performance, and listening for any hint of abnormal vibration. A molding press drifts out of spec, so you isolate the fault, consult schematics, replace a failed sensor, and safely return the line to rate. Between calls, you complete scheduled PMs so small issues never become large outages, then collaborate with production and engineering on improvements that boost uptime and quality.
