@Abdul majid bakti ,ControlsGuy25,
thanks for your great supprot, I apologize for the very slow response. We're trying to find fault with our machine.
At first, our machine is in standby state. With all core states A7 and nothing alarm on HMI.
When operating, the turbine trips when the clutch is open 0n 67% With many indications appearing on HMI. After being traced, the voltage on QD1 DTBA does not exist due to a broken fuse. So replace the fuse. After rebooting, the status on Core S remains at A6. We tried to measure the voltage again, +- is 133 VDC, but + ground is -5.6 VDC and - Ground is 139 VDC. We have checked this fault as well and found a short circuit on terminal 16 QD1 DTBA.
After that we reboot again. But the core S is still on the A6. We tried to go to revision panel and found S-TCE1 not detected and core P card TCEA out of sync.
once again thanks for your valuable reply and support.

@ControlsGuy25 , @CSA
Forgive me for the very slow response to update information related to this disruption.
thank you very much for the support and steps troubleshooting that has been informed.
in recent days we are trying to resolve the disruption in our unit. the status of A6 on the core <S> is normal. the problem on ribbon cable from TCQA to TCTG core <P>. initially we thought the problem on the TCEA card slot 3, after we replaced. the problem still arises. we checked on IONET on TCQC as well, but the result is altogether.
once again thanks for totaly support, thankyou very much @ControlsGuy25 , you are very good in solving this disorder. thank you also for @CSA for support, I also read some of your trends and comments on several forums. I put it all together to resolve the disruption in our unit.
