What causes fault code ASRS-CONV1 (AS/RS Infeed/Outfeed Conveyor — Handoff Fault)?

Conveyor did not position load correctly at the handoff point — load short or overshot. Crane platform position does not align with conveyor — crane X or Y position off. Load is jammed or stuck on the conveyor infeed — damaged pallet, broken conveyor roller. Handoff sensor sequence not completed — load present sensors did not transition in correct order. Conveyor motor tripped during handoff — VFD fault or motor overload

How do I fix fault code ASRS-CONV1?

Check load position on conveyor — is it at the correct handoff point?. Verify crane platform is aligned with the conveyor height and position. Inspect handoff zone for physical obstructions — debris, pallet fragments, wrapping material. Check all handoff sensors — load present on conveyor, load clear on crane, alignment sensors. Verify conveyor motor is running — check VFD status for faults. If load is partially transferred, manually complete or retract the load (follow LOTO procedures)

AS/RS Infeed/Outfeed Conveyor — Handoff Fault

ASRS-CONV1

Load transfer between the AS/RS infeed/outfeed conveyor and the crane platform failed. Load did not complete the handoff within the allowed time.

Probable Causes (ranked)

Conveyor did not position load correctly at the handoff point — load short or overshot
Crane platform position does not align with conveyor — crane X or Y position off
Load is jammed or stuck on the conveyor infeed — damaged pallet, broken conveyor roller
Handoff sensor sequence not completed — load present sensors did not transition in correct order
Conveyor motor tripped during handoff — VFD fault or motor overload

Fix Steps

1 Check load position on conveyor — is it at the correct handoff point?
2 Verify crane platform is aligned with the conveyor height and position
3 Inspect handoff zone for physical obstructions — debris, pallet fragments, wrapping material
4 Check all handoff sensors — load present on conveyor, load clear on crane, alignment sensors
5 Verify conveyor motor is running — check VFD status for faults
6 If load is partially transferred, manually complete or retract the load (follow LOTO procedures)

Field Trick

The handoff point between conveyor and crane is the highest-maintenance area in any AS/RS system. Put it on a weekly inspection schedule — check roller alignment, sensor cleanliness, and conveyor chain tension at the handoff zone. 40% of AS/RS downtime happens at this one point.
