What causes fault code PAL-TOP1 (Palletizer Top Frame / Top Sheet Dispenser Fault)?

Top frame magazine empty — no frames available. Vacuum pickup failed — cups worn or vacuum pump issue. Top frame jammed in the magazine — frames stuck together or misloaded. Placement mechanism position off — top frame not centered on the pallet. Top frame size wrong — different product SKU requires different frame size

How do I fix fault code PAL-TOP1?

Reload top frame magazine with correct size frames. Check vacuum cups on the pickup head — replace worn cups. Verify vacuum level — minimum 18 inches Hg at the pickup cups. Check frame magazine loading — frames should be flat and not stuck together. Adjust placement mechanism position if top frame is landing off-center. Verify correct recipe/frame size is selected for the current product run

Field Trick

Top frames made of corrugated board curl in humidity. When they curl, the vacuum cups can't seal on the surface. Store top frames flat in a dry area and rotate stock — first in, first out. Frames that have been sitting for months in a humid warehouse will jam the magazine and frustrate everyone.
