Torque Limiter
| 1 | Slips at start-up |
|---|
| Cause 1 | Insufficient set torque | Solution | Readjust to the slip torque that matches the machine |
|---|---|---|---|
| Cause 2 | Oil and moisture adhere to the friction surface | Solution | Clean up |
| Cause 3 | Friction facings life | Solution | Replace friction facings |
| Cause 4 | Overload | Solution | Remove overload |
| 2 | No slip when overloaded |
|---|
| Cause 1 | High slip torque | Solution | Adjust to the slip torque that matches the machine |
|---|
| 3 | Frequently slips during normal operation |
|---|
| Cause 1 | Insufficient set torque | Solution | Readjust to the slip torque that matches the machine |
|---|---|---|---|
| Cause 2 | High frequent slips decreased torque | Solution | Readjust to the slip torque that matches the machine or replace the friction facings |
| Cause 3 | Loose adjustment nut or adjustment bolt | Solution | Readjust to the slip torque that matches the machine |
