    MSV Not Operating Properly on Mark V

    The steam turbine manufacturer is General Electric. The turbine is an SAC2, automatic extraction condensing steam turbine. The servo manufacturer is MOOG. There were other parties who contributed to helping resolve the issue. PSM and MD&A provided support troubleshooting to get the issue...

    MSV Not Operating Properly on Mark V

    We confirmed with the turbine manufacturer that we indeed had been using the wrong servo since the plant was commissioned. The servo manufacturer who we had been communicating with directly, without confirmation from the turbine manufacturer, was skeptical about selling us the one that we...

    MSV Not Operating Properly on Mark V

    I don't think we had any relevant diagnostic alarms present. I will check on that. I recalibrated the LVDTs the valve position is showing about +0.10% at true 0. We tested the theory that the servo current should go to a negative value to allow for the valve to open. That was not the case...

    MSV Not Operating Properly on Mark V

    We are attempting to restart our steam turbine after a loss of trip oil. We are having issues with the MSV2 valve "popping" open once the operators select reset. The controller is a Mark V TMR. Once operators select reset on the controller, the turbine starts to roll off. The highest we let it...

    LCI Fault Message

    Yes, our LCI was idle when the alarm occurred. It only happened twice and has not been an issue since. We do not cycle our units except to do an offline water wash. So the next time we are required to use it could be to restart after a trip and we do not want to have a failed restart after a...

    LCI Fault Message

    We had the LCI fault message "FCGD Misoperation" occur on our GE Innovation Series LCI. This fault message came in twice on 8/7 and cleared both times. Per GEH-6373 it seems that this should have been followed by other fault or alarm messages. There were none. I opened the cabinets and the...

    Wiring Up 7 Emergency Stops on a Conveyor

    ...yeah, seems like some are missing the point that we are here to help each other out, and solve their problem. Not to tout about how much we know.

    Wiring Up 7 Emergency Stops on a Conveyor

    How are the e-stops wired? You need to make sure that all of the estops are wired in series with one another and that when each e-stop is pressed the contacts are opening on that e-stop, breaking the circuit. How is the PLC wired? Is each e-stop wired back to its own PLC terminal point, or...

    Emerson Ovation vs GE Mark VIe

    We have Mark V Control systems on our turbines and have considered upgrading to all of the newer versions that GE offers. We have also considered other systems such as the Emerson Ovation system. The problem with GE's upgrade is that it is not an open control system. Many people we have spoken...

    ABB INFI90 BRC100 ROM Checksum Error..

    The manual says to contact ABB. Is it doing it when you are attempting to do a download to the controller or intermittently? Have you attempted to perform any special operations to the controller? Following the ABB flowchart provided in the manual the next step would be to replace the...

    Speedtronic System - GE

    I totally agree with CSA in this matter. I have heard complaints from those who have upgraded their Mark V is that they do not have as much insight in the logic and functionality. I do not know how much that could influence your decision but it did ours. We were at one point considering...
