Conveyor Fault — Belt Slip Detected
What This Fault Means
A belt slip fault indicates the speed sensor detected a difference between the drive pulley speed and belt speed exceeding the configured threshold. This means the belt is sliding on the drive pulley instead of tracking properly.
Common Causes
- Insufficient belt tension
- Wet or contaminated drive pulley (oil, dust, ice)
- Worn or glazed pulley lagging
- Overloaded conveyor exceeding drive traction capacity
- Speed sensor malfunction or misalignment
Recommended Fix
- Check belt tension — adjust the take-up (gravity or screw type) to manufacturer specification.
- Clean the drive pulley surface and remove any contamination.
- Inspect the pulley lagging (rubber or ceramic) for wear — replace if smooth or detached.
- Reduce the load if the conveyor is consistently overloaded.
- Verify the speed sensor alignment and gap to the target wheel.
