What causes fault code CONV-019 (Conveyor Weighing Scale Overload)?

Product weight exceeds scale rated capacity. Multiple products on scale platform simultaneously. Scale zeroed incorrectly — tare weight wrong. Debris on scale platform adding weight. Load cell mechanical overload — exceeded max rated capacity

How do I fix fault code CONV-019?

Verify product weight vs scale capacity rating. Ensure only one product at a time on scale platform — adjust conveyor spacing. Re-zero/tare the scale with platform empty and clean. Clean scale platform — remove any debris or product buildup. Check load cell output — may be permanently damaged if severely overloaded. Inspect load cell for physical deformation — replace if damaged

Conveyor Weighing Scale Overload

CONV-019

In-motion conveyor scale reports weight exceeding maximum capacity. Scale accuracy compromised.

Probable Causes (ranked)

Product weight exceeds scale rated capacity
Multiple products on scale platform simultaneously
Scale zeroed incorrectly — tare weight wrong
Debris on scale platform adding weight
Load cell mechanical overload — exceeded max rated capacity

Fix Steps

1 Verify product weight vs scale capacity rating
2 Ensure only one product at a time on scale platform — adjust conveyor spacing
3 Re-zero/tare the scale with platform empty and clean
4 Clean scale platform — remove any debris or product buildup
5 Check load cell output — may be permanently damaged if severely overloaded
6 Inspect load cell for physical deformation — replace if damaged

Field Trick

If the scale suddenly reads heavy on everything, check under the platform. Product crumbs and debris build up under the scale and add false weight. A 5-minute cleaning fixes it.
