What causes fault code CONV-005 (Conveyor Chain Stretch Alarm)?

Normal chain wear — chains stretch over time and need replacement. Lubrication inadequate — dry chain wears faster. Overloaded conveyor — excessive weight accelerates wear. Chain and sprocket mismatch — wrong pitch or worn sprockets. Corrosive environment eating chain material

How do I fix fault code CONV-005?

Measure chain stretch — compare 10-link section to new chain spec. If >3% elongation, chain needs replacement. Inspect sprocket teeth for hooking (worn into hook shape) — replace with chain. Adjust take-up to re-tension — if at max travel, chain is too long. Check lubrication system — verify oil/grease is reaching chain pins. When replacing chain, always replace sprockets at the same time

Conveyor Chain Stretch Alarm

CONV-005

Chain-driven conveyor reports excessive chain elongation. Take-up travel is at maximum or chain has stretched beyond adjustment range.

Probable Causes (ranked)

Normal chain wear — chains stretch over time and need replacement
Lubrication inadequate — dry chain wears faster
Overloaded conveyor — excessive weight accelerates wear
Chain and sprocket mismatch — wrong pitch or worn sprockets
Corrosive environment eating chain material

Fix Steps

1 Measure chain stretch — compare 10-link section to new chain spec
2 If >3% elongation, chain needs replacement
3 Inspect sprocket teeth for hooking (worn into hook shape) — replace with chain
4 Adjust take-up to re-tension — if at max travel, chain is too long
5 Check lubrication system — verify oil/grease is reaching chain pins
6 When replacing chain, always replace sprockets at the same time

Field Trick

Lift the chain off the sprocket. If you can pull it away from the sprocket tooth more than half a tooth pitch, it's stretched and needs replacement.
