| 1 | An overload occurred but the device did not operate |
|---|
| Cause 1 | Torque setting is too high | Solution | Gradually increase the set torque from a low torque and readjust it to the torque that suits the machine. |
|---|
| 2 | Shock Guard activates frequently during normal operation |
|---|
| Cause 1 | Insufficient set torque | Solution | Increase the torque according to the torque adjustment instructions. |
|---|---|---|---|
| Cause 2 | Torque decreased due to the high number of operations | Solution | Shock Guard replacement |
| Cause 3 | Loose adjustment nut | Solution | After adjusting the torque, press the nut and secure it with the screw. |
| 3 | An overload signal is output, but Shock Guard does not operate. |
|---|
| Cause 1 | Proximity sensor gap adjustment error | Solution | Adjusting the proximity sensor gap |
|---|---|---|---|
| Cause 2 | Proximity sensor failure | Solution | Replacing the proximity sensor |
| 4 | After an overload occurred, I tried to reset the unit but it did not reset. |
|---|
| Cause 1 | Because the recovery rotation speed is high, it continues to operate even after recovery. | Solution | Reduce the recovery rotation speed (manual recovery) Inching operation |
|---|
| 5 | There was a rattle in Shock Guard |
|---|
| Cause 1 | Because the set torque is close to the normal torque of the device, Shock Guard starts to operate at peak loads, and it appears that rattle is occurring. | Solution | Set the torque as high as possible while still protecting the equipment. |

| 6 | An overload occurred but the device did not operate |
|---|
| Cause 1 | Torque setting is too high | Solution | Gradually increase the set torque from a low torque and readjust it to the torque that suits the machine. |
|---|---|---|---|
| Cause 2 | The mounting bolts for the sprocket, etc. are too long, causing the bolts to come into contact with the flange of the hub, preventing Shock Guard from working. | Solution | Change to the appropriate bolt length |
| 7 | Shock Guard activates frequently during normal operation |
|---|
| Cause 1 | Insufficient set torque | Solution | Increase the torque according to the torque adjustment instructions. |
|---|---|---|---|
| Cause 2 | Torque decreased due to the high number of operations | Solution | Shock Guard replacement |
| Cause 3 | Loose adjustment nut | Solution | After adjusting the torque, press the nut and secure it with the screw. |
| 8 | An overload signal is output, but Shock Guard does not operate. |

| 10 | There was a rattle in Shock Guard |
|---|
| Cause 1 | Because the set torque is close to the normal torque of the device, Shock Guard starts to operate at peak loads, and it appears that rattle is occurring. | Solution | Set the torque as high as possible while still protecting the equipment. |

| 11 | An overload occurred but the device did not operate |
|---|
| Cause 1 | Torque setting is too high | Solution | Gradually increase the set torque from a low torque and readjust it to the torque that suits the machine. |
|---|
| 12 | Shock Guard activates frequently during normal operation |
|---|
| Cause 1 | Insufficient set torque | Solution | Increase the torque according to the torque adjustment instructions. |
|---|---|---|---|
| Cause 2 | Torque decreased due to the high number of operations | Solution | Shock Guard replacement |
| 13 | An overload signal is output, but Shock Guard does not operate. |
|---|
| Cause 1 | Limit switch misadjustment | Solution | Adjust the limit switch installation position |
|---|---|---|---|
| Cause 2 | Faulty limit switch | Solution | Limit switch replacement |
| 14 | After an overload occurred, I tried to reset the unit but it did not reset. |
|---|
| Cause 1 | Because the recovery rotation speed is high, it continues to operate even after recovery. | Solution | Reduce the recovery rotation speed (manual recovery) Inching operation |
|---|
| 15 | There was a rattle in Shock Guard |
|---|
| Cause 1 | Because the set torque is close to the normal torque of the device, Shock Guard starts to operate at peak loads, and it appears that rattle is occurring. | Solution | Set the torque as high as possible while still protecting the equipment. |

TGK series
| 16 | Air is supplied to Shock Guard, but the clutch does not turn on. |
|---|
| Cause 1 | Regulator air pressure setting too low | Solution | Adjust the regulator air pressure setting |
|---|---|---|---|
| Cause 2 | Air leak from the seal | Solution | Replacing the seal |
| Cause 3 | Incorrect air piping | Solution | Check the air piping |
| 17 | Shock Guard does not operate when an overload occurs |
|---|
| Cause 1 | Regulator air pressure setting too high | Solution | Adjust the regulator air pressure setting |
|---|---|---|---|
| Cause 2 | Due to the high rotation speed, the air inside the cylinder is not completely discharged when overloaded. | Solution | A quick exhaust valve is installed near the air supply port of Shock Guard |
| 18 | No overload has occurred, but Shock Guard has been activated |
|---|
| Cause 1 | Limit switch misadjustment | Solution | Adjust the limit switch installation position |
|---|---|---|---|
| Cause 2 | Faulty limit switch | Solution | Limit switch replacement |
| 19 | After overload or clutch OFF, the clutch does not turn ON even though the reset operation is performed. |
|---|
| Cause 1 | Because the recovery rotation speed is high, it recovers once and then restarts. | Solution | Decrease the return speed Inching operation |
|---|---|---|---|
| Cause 2 | Since the normal load is lower than the return torque, the driven side rotates without the clutch being fully turned on. | Solution | Set the air pressure to a low value, turn the clutch ON, then return to the normal pressure setting and operate. |
