70 CS sensor: CS stands for Commutation Sensor. This sensor is necessary to rotate the UEP tool motor.
71 17.2. Recommended Action Error Countermeasure ZERO error CAL error ・Check the connection between a tool and sensor cable. Or, replace them. ・Check if the tool is running during the checking is being made. Buffer Full error ・Set the setting of waveform memory function select to 1 or 4. Setting error ・Check and correct the mode settings parameters. Make sure that they are logically correct like the formula START
72 greater than necessary. Select the AC reactor good for each UEPD capacity. Restart Prevention ・Clear this error after you confirm the safety. The tool starts running when the tool run signal is on. Also, the insufficient amount of power may cause this feature to be triggered. Be sure to supply the UECD with the proper amount of power. Excessive Load (Thermal) ・Remove the excessive load, change the bolt / nut fastening pattern, and / or use the one size up UECD system. Sensor Error ・Refer to the Trouble Shooting for more information. CPU Error ・Check that there is no external noise effect on CPU. Input Signal Error ・Refer to the Trouble Shooting for more information. *1: Check the tightening time from start torque to cut, number of pulses, and angle per application to make the appropriate settings.
73 18. Troubleshooting Phenomenon Probable Cause Recommended Action Driver unit Not Powered ・ Not plugged in ・ Switched off ・ Main power voltage drop ・ Incorrect size of UECD connected to UEP tool ・ Short-circuited ・ Blown fuse ●Plug the UECD in. ●Switch on the UECD. ●Make the correct connection. ●Repair or replace the UECD. Driver Unit Error ・ The inherent intelligence of UEP system works. ●Check the error status on the DRIVER DATA screen and switch it on after correcting the problem. Sensor error E-C.S. detected * ・ UECD unconnected to UEP tool ・ Broken wire ●Confirm the cable connection. ●Repair or replace the UECD. Tool UEP will not run. ・ Not plugged in ・ Cable misconnection ・ Broken wire ・ Driver unit error ・ Overworking the UEP tool ●Switch on the UEP system. ●Make the correct connection. ●Repair or replace the UEP. ●Remove the excessive load. UEP runs in a reverse direction. ・ Reverse lever energized in error ●Check the reverse lever position. UEP will not run correctly. ・ Broken wire ・ Driver error ・ Mode settings incorrectly made – i.e. fastening control method ●Repair or replace the UEP. ●See Chapter 17.2 Recommended Action. ●Work on the correct settings. Error message E.SIG displayed in operation* ・ Reverse lever energized in error ●Switch it on again. No tool power ・ Oil leakage ●Repair or replace the UEP. Heat generated ・ Overworking the UEP tool ●Remove the excessive load. Not torque controlled ・ Set the MODE 4 of DRIVER DATA to 2. ・ Set the Control Method of MODE settings to 3. ●Confirm the settings. UEP-MC tool pulsing longer than it should till it shuts off ・ Rise in heat inside UEP-MC ・ Oil leakage ●Remove the excessive load. ●Cool down the tool. ●Repair or replace the UEP-MC.
