Common to TGB series and TGX series

1	Overload occurred but not activated

Cause 1	Set torque too high	Solution	Gradually increase the set torque from a lower torque and readjust to a torque suitable for the machine

Back to list

2	Shock Guard is activated frequently during normal operation

Cause 1	Insufficient set torque	Solution	Increase torque according to the torque adjustment instructions
Cause 2	Torque reduced due to high number of operations	Solution	Replace Shock Guard
Cause 3	Loose adjustment nuts	Solution	After adjusting the torque, press the nut and fix it with the set screw

Back to list

3	An overload signal is output but Shock Guard is not activated

Cause 1	Proximity sensor gap adjustment failure	Solution	Adjust the proximity sensor gap
Cause 2	Faulty proximity sensor	Solution	Replace proximity sensor

Back to list

4	After an overload occurred, the reset operation is performed but not reset

Cause 1	High reset rotation speed, so it operates again even if it reset once	Solution	Reduce the reset rotation speed (Manual reset ) Perform inching operation

Back to list

5	Backlash occurred from Shock Guard

Cause 1	The set torque is close to the normal operating torque of the equipment, so Shock Guard starts to operate at peak load and appears to backlash	Solution	Set torque as high as possible within the range that can protect the equipment.

Common to TGE series and TGF series

6	Overload occurred but not activated

Cause 1	Set torque too high	Solution	Gradually increase the set torque from a lower torque and readjust to a torque suitable for the machine
Cause 2	Mounting bolts for sprockets etc. are too long, so the bolts and the flange of hub come into contact and Shock Guard does not work	Solution	Change to appropriate bolt length

TGK Series

16	Air supplied to Shock Guard, but the clutch does not turn on

Cause 1	Regulator air pressure set too low	Solution	Adjust regulator air pressure setting
Cause 2	Air leakage at seals	Solution	Replace seals
Cause 3	Incorrect air pipework	Solution	Check air pipework

Back to list

17	Shock Guard does not activate when overloaded

Cause 1	Regulator air pressure set too high	Solution	Adjust regulator air pressure setting
Cause 2	Due to high rotation speeds, air in the cylinder is not completely discharged when overloaded	Solution	Install a quick exhaust valve near the air supply port of Shock Guard

Back to list

18	No overload, but Shock Guard activated

Cause 1	Poor adjustment of limit switches	Solution	Adjust the installation position of the limit switch
Cause 2	Faulty limit switches	Solution	Replace limit switches

Back to list

19	After overload or clutch off, clutch does not turn on even though the reset operation is performed

Cause 1	High reset rotation speed, so it operates again even if it reset once	Solution	Reduce the reset rotation speed Perform inching operation
Cause 2	The normal load is lower than the reset torque, so the driven side rotates without the clutch being turned on completely	Solution	Lower the air pressure setting, turn on the clutch once, then return to the normal pressure setting before driving
