A chewed wire, a high trip setting, and a snapped shaft. đ ī¸
âA recent failure on our crumbler was a sharp reminder of why physical PM checks matter:
âTrigger: Rodent damage cut the proximity sensor wireâleaving SCADA blind to roller misalignment.
âEscalation: Overload amps were set too high, so the breaker didn't trip before the main shaft sheared.
âAction: Repaired the sensor, lowered the overload setting for fast tripping, and completed mechanical repairs.
âThe Lesson: Preventive maintenance isn't just watching screens. Itâs checking physical wiring, verifying trip settings, and stopping small flaws before they cause major downtime.
