What causes fault code PKG-006 (Checkweigher Reject)?

Underfill — product doesn't meet minimum weight specification. Overfill — product exceeds maximum weight specification. Checkweigher calibration drifted — readings inaccurate. Vibration from adjacent equipment affecting weight reading. Draft/air current affecting scale accuracy

How do I fix fault code PKG-006?

Check rejected product on bench scale — verify actual weight. If weight is actually in spec, recalibrate checkweigher with test weights. Adjust fill machine if underfill/overfill is confirmed. Check for vibration — isolate checkweigher from conveyor vibration. Install draft shields if air currents are affecting readings. Review reject rate trend — sudden increase indicates filling problem

Probable Causes (ranked)

Underfill — product doesn't meet minimum weight specification
Overfill — product exceeds maximum weight specification
Checkweigher calibration drifted — readings inaccurate
Vibration from adjacent equipment affecting weight reading
Draft/air current affecting scale accuracy

Fix Steps

1 Check rejected product on bench scale — verify actual weight
2 If weight is actually in spec, recalibrate checkweigher with test weights
3 Adjust fill machine if underfill/overfill is confirmed
4 Check for vibration — isolate checkweigher from conveyor vibration
5 Install draft shields if air currents are affecting readings
6 Review reject rate trend — sudden increase indicates filling problem

Field Trick

Run 10 known-weight test packs through the checkweigher. If they all read within ±1g of actual, the checkweigher is fine and your filler is the problem.
