What causes fault code ASRS-WEIGHT1 (AS/RS Overweight Load Detected)?

Load genuinely overweight — product or pallet exceeds AS/RS rated capacity. Scale calibration drift — load cells reading high due to calibration error. Water or moisture added weight — product absorbed moisture during transit or storage. Wrong product loaded on pallet — heavier product than system expects. Scale platform fouled — debris under the platform adding false weight

How do I fix fault code ASRS-WEIGHT1?

Verify load weight with an independent scale (forklift scale or floor scale) — confirm actual weight. If genuinely overweight, reject the load — do NOT override the weight limit. If scale reads high, calibrate using a known test weight — most AS/RS scales have a calibration procedure. Check scale platform for debris underneath — clean the area under and around the load cells. Verify scale load cells are not damaged — inspect for physical impact damage. Update WMS with actual weights for the product SKU to prevent future overweight loads

AS/RS Overweight Load Detected

ASRS-WEIGHT1

Load weight measurement at the AS/RS infeed station or on the crane platform exceeded the maximum allowable weight. System will not store an overweight load.

Probable Causes (ranked)

Load genuinely overweight — product or pallet exceeds AS/RS rated capacity
Scale calibration drift — load cells reading high due to calibration error
Water or moisture added weight — product absorbed moisture during transit or storage
Wrong product loaded on pallet — heavier product than system expects
Scale platform fouled — debris under the platform adding false weight

Fix Steps

1 Verify load weight with an independent scale (forklift scale or floor scale) — confirm actual weight
2 If genuinely overweight, reject the load — do NOT override the weight limit
3 If scale reads high, calibrate using a known test weight — most AS/RS scales have a calibration procedure
4 Check scale platform for debris underneath — clean the area under and around the load cells
5 Verify scale load cells are not damaged — inspect for physical impact damage
6 Update WMS with actual weights for the product SKU to prevent future overweight loads

Field Trick

AS/RS cranes are rated for a specific load weight, and that rating includes the pallet. If your system is rated for 2,500 lbs and your product weighs 2,400 lbs, you only have 100 lbs left for the pallet. Hardwood pallets weigh 50-75 lbs, but a wet pallet can weigh 120+ lbs. Weigh your pallets, not just your product.
