What causes fault code ASRS-002 (AS/RS Load Overweight)?

Pallet loaded beyond weight spec by warehouse personnel. Weight sensor calibration drift — reading higher than actual. Tare weight offset incorrect — empty carrier not zeroed. Moisture absorption in product increasing weight over time. Wrong SKU assigned to location — lighter item expected

How do I fix fault code ASRS-002?

Remove pallet from crane and weigh on floor scale to verify. If actually overweight, repalletize to meet weight spec. If weight is within spec, recalibrate crane load cells. Zero tare weight with empty carrier on crane. Verify WMS has correct weight data for the SKU

AS/RS Load Overweight

ASRS-002

Load weight exceeds maximum rated capacity for the crane or rack location. Load was rejected or crane stopped before storing.

Probable Causes (ranked)

Pallet loaded beyond weight spec by warehouse personnel
Weight sensor calibration drift — reading higher than actual
Tare weight offset incorrect — empty carrier not zeroed
Moisture absorption in product increasing weight over time
Wrong SKU assigned to location — lighter item expected

Fix Steps

1 Remove pallet from crane and weigh on floor scale to verify
2 If actually overweight, repalletize to meet weight spec
3 If weight is within spec, recalibrate crane load cells
4 Zero tare weight with empty carrier on crane
5 Verify WMS has correct weight data for the SKU

Field Trick

Put a known weight (like a full water drum — ~450 lbs) on the crane and check the reading. If it's off by more than 2%, recalibrate the load cells.
