Piler Traverse Position Error

Piler horizontal traverse position does not match expected location. Cannot confirm alignment with target bay.

Probable Causes (ranked)

• Traverse encoder wheel slipping on rail — worn rubber tire on encoder wheel
• Bar code or reflector positioning system misread — dirty reader lens
• Rail obstruction causing traverse motor to stall
• Traverse drive belt or chain skip — teeth worn or tension lost
• PLC traverse position counter accumulated error over multiple cycles

Fix Steps

1. 1 Check traverse encoder wheel contact with rail — replace if rubber tire is worn smooth
2. 2 Clean bar code reader or reflector lens — use isopropyl alcohol and lint-free cloth
3. 3 Walk the rail — check for debris, fallen product, or hardware on travel path
4. 4 Inspect traverse drive belt/chain tension and tooth engagement
5. 5 Re-home piler traverse by driving to reference mark and resetting position counter
6. 6 If using bar code positioning, verify all bay labels are clean and not peeling
