Symptoms
The weaving machine reports a let-off tension anomaly. The warp beam let-off tension is outside the set range.
Possible Causes
- Let-off drive motor or controller fault
- Back rest or tension sensor calibration drift
- Warp beam diameter calculation error
Troubleshooting Steps
- Step 1: Verify the let-off motor and controller operation
System maintains correct tension - Step 2: Check the tension sensor calibration
Sensor reads accurately - Step 3: Verify the warp beam diameter setting
Diameter matches the actual beam
How to Reset
To reset: Restore correct let-off tension, then clear the alarm.
