Conveyor Jam Detected

Photo-eye or motor current sensing indicates product jam on conveyor section. Conveyor stopped to prevent damage.

Probable Causes (ranked)

• Product misaligned or fallen on conveyor — physical blockage
• Accumulation zone full — downstream equipment stopped or faulted
• Belt or chain slipping — worn sprocket or low tension
• Photo-eye blocked by debris, dust, or condensation on lens
• VFD tripped on overcurrent protecting motor from overload

Fix Steps

1. 1 Clear jammed product manually — check for damage to product and conveyor
2. 2 Verify downstream equipment is running and accepting product
3. 3 Inspect belt/chain tension and sprocket wear — adjust or replace as needed
4. 4 Clean photo-eyes and reflectors with soft cloth, verify alignment with test mode
5. 5 Check VFD display for fault code — reset if overcurrent was transient
6. 6 Monitor motor current after clearing — sustained high amps indicates mechanical binding
