What causes fault code PAL-007 (Palletizer Infeed Backup)?

Palletizer cycle time slower than production rate. Frequent faults/stops on palletizer reducing throughput. Pattern change in progress — slower cycle during changeover. Pallet dispenser not keeping up with demand. Discharge conveyor full — completed pallets not being removed

How do I fix fault code PAL-007?

Check palletizer status — clear any active faults. Verify discharge side — are completed pallets being removed by forklift?. If changeover, allow extra time for pattern setup to complete. Check pallet magazine — refill if low or empty. Review production rate vs palletizer rated speed — may need to slow production. Check for recurring faults that keep stopping the palletizer
