Why did Line 2 stop at 3:05?

Why did Line 2 stop at 3:05 this morning?

Line 2 had a 42-second micro-stop at 03:05:18. The Downtime Analyzer ran a post-mortem at 03:07 and identified the root cause as capper torque drift on Capper 2 — the torque setpoint had drifted from 14.2 N·m down to 13.6 N·m, just below the lower control limit. The capper auto-corrected and the line resumed within spec.

Has this happened before on Capper 2?

Yes — Capper 2 has had three torque drift events in the past 30 days, all auto-corrected. The pattern is consistent: drift accumulates over ~48 hours of continuous operation. I'd recommend tightening the auto-correction interval from 4 hours to 2 hours, or scheduling a calibration check during the next changeover.
