What causes fault code CONV-009 (Conveyor Metal Detector Trip)?

Actual metal contamination in product — requires investigation. Metal detector sensitivity set too high — false positives. Product effect — moisture, salt, or mineral content in product triggers detector. Vibration from conveyor causing false readings. Metal detector calibration drifted

How do I fix fault code CONV-009?

Retrieve rejected product — inspect for visible metal contamination. Run test samples (ferrous, non-ferrous, stainless steel) through detector. If false positive, recalibrate metal detector per manufacturer procedure. Adjust sensitivity — start at minimum and increase to meet spec. Check conveyor for vibration — tighten mounting bolts, check motor balance. Verify reject mechanism is actuating properly and confirmed by sensor

Conveyor Metal Detector Trip

CONV-009

Inline metal detector triggered on product passing through. Product has been rejected or line has stopped for inspection.

Probable Causes (ranked)

Actual metal contamination in product — requires investigation
Metal detector sensitivity set too high — false positives
Product effect — moisture, salt, or mineral content in product triggers detector
Vibration from conveyor causing false readings
Metal detector calibration drifted

Fix Steps

1 Retrieve rejected product — inspect for visible metal contamination
2 Run test samples (ferrous, non-ferrous, stainless steel) through detector
3 If false positive, recalibrate metal detector per manufacturer procedure
4 Adjust sensitivity — start at minimum and increase to meet spec
5 Check conveyor for vibration — tighten mounting bolts, check motor balance
6 Verify reject mechanism is actuating properly and confirmed by sensor

Field Trick

Send the same product through 3 times. If it trips every time, it's real contamination. If it's intermittent, it's likely product effect or vibration.
