What causes fault code PKG-ERECT1 (Case Erector — Case Magazine Empty / Low)?

Magazine not refilled in time — operator missed the low-level warning. Low-level sensor failed — did not alert operator before empty. Wrong case size loaded — blanks are jammed in the magazine. Magazine guide rails not adjusted for case blank size — blanks are skewing or falling over. Case blank quality poor — warped or moisture-damaged blanks won't feed properly

How do I fix fault code PKG-ERECT1?

Load fresh case blanks into the magazine — verify correct case size and orientation. Check magazine guide rail adjustment — rails should be snug to blank width with 1/8 inch clearance. Verify low-level sensor is functioning — block and unblock to confirm signal to PLC. If blanks are jamming, inspect for warped or moisture-damaged blanks — remove and discard defective blanks. Adjust vacuum suction cups if blanks not separating properly — cups must grip cleanly without double-feeding. Restart the erector cycle after loading — most require a manual start after empty magazine

Field Trick

Case blanks from the bottom of the pallet are almost always moisture-damaged and warped. They jam the magazine every time. Train operators to inspect the bottom 2 layers of blanks and discard any that are soft or warped. This prevents 90% of case erector jams.
