What causes fault code CONV-016 (Conveyor Spiral/Helix Fault)?

Belt tension incorrect — too tight causes motor overload, too loose causes slipping. Chain lubrication dry in spiral section — increased friction. Product jam in spiral — stuck product stops belt movement. Drive chain or sprocket wear — elongation causing position errors. Ambient temperature change affecting belt length

How do I fix fault code CONV-016?

Check belt/chain tension — adjust per manufacturer spec for operating temperature. Inspect spiral section for product jams — clear from inside if accessible. Verify lubrication system is delivering to spiral chain guides. Check drive sprocket and chain wear — replace if chain >3% elongated. If seasonal temp change, readjust tension for current conditions. Run spiral empty to verify smooth operation before adding product

Conveyor Spiral/Helix Fault

CONV-016

Spiral or helix conveyor system fault. Belt or chain in spiral section reporting tension, tracking, or speed issue.

Probable Causes (ranked)

Belt tension incorrect — too tight causes motor overload, too loose causes slipping
Chain lubrication dry in spiral section — increased friction
Product jam in spiral — stuck product stops belt movement
Drive chain or sprocket wear — elongation causing position errors
Ambient temperature change affecting belt length

Fix Steps

1 Check belt/chain tension — adjust per manufacturer spec for operating temperature
2 Inspect spiral section for product jams — clear from inside if accessible
3 Verify lubrication system is delivering to spiral chain guides
4 Check drive sprocket and chain wear — replace if chain >3% elongated
5 If seasonal temp change, readjust tension for current conditions
6 Run spiral empty to verify smooth operation before adding product

Field Trick

Spiral conveyors tighten in cold weather and loosen in hot weather. If you have tension problems that come and go seasonally, install an automatic tension adjustment.
