bkarim55, My first inclination is to say there is a combustion problem because of the cold spot around exh T/C #10, but I hesitate because: 1) I have no personal experience with MS5002D machines and their swirl patterns, and, 2) because the highest exh T/C is not close (adjacent) to the...

Paul, GE Aircraft Engine in Evendale, OH, USA, determines the control systems which are acceptable for the different types of LM units--they are NOT all the same, even within a model line (LM2500; LM5000; LM6000; etc.). In general, it's the speed of the processors ("scan rate") which...

bkarim55, Exhaust temperature spreads (which are the indicators of combustion troubles) are the result of: 1) too little fuel getting into one or more combustors; 2)too much air getting into one or more combustors; 3) too much fuel getting into one or more combustors. The causes...

abdi, The clearances between the clutch plates are very small and what's probably happening is that without the mechanical "drag" of the liquid fuel pump the output shaft of the clutch is spinning. <b>HOWEVER:</b> If for some reason the clutch plates have seized then it would appear as if...

BigLidster, This is an easy one--now that I understand what it is exactly you're wanting to do. The only <I> functions you need IDOS for are anything to do with displays that involve putting data values on the screen--the Main Display, any animated display, any User Defined (Demand)...

Adam, a.k.a. BigLidster, Another thing to consider is that IDOS was written for serial mouse and a serial or PS/2 keyboard.... Are you sure your VM is configured properly for "passing" the keyboard and mouse to IDOS? I'm not sure how you would do that, but I'm not aware that IDOS can be...

saurabhstalone, Thanks for the feedback, ..., but, I have never heard of "tuning a re-ignition timer." And there's more--the purpose of re-energizing the ignitors (spark plugs) in the primary combustion zone is to re-establish diffusion flame in the primary combustion zone (which...

Adam, a.k.a. BigLidster, I've never tried to run IDOS on a virtual machine, but I can tell you that there were some versions of BIOS that would not allow IDOS to run, and one of the signature indicators of a BIOS compatibility issue was the keyboard not working. Some IBM laptops used a BIOS...

JoTang84, Loss of excitation is a serious condition whose cause must be investigated and understood before re-applying excitation and re-synghronizing the generator. (We presume you are talking about a synchonous generator that is synchronized to grid with other generators, not a single...

309Eguy, It's virtually impossible the measure the output of the rotating diode wheel of a brushless exciter. One can only measure the voltage applied to the stationary field of the rotating generator. It's much easier to measure the DC current flowing through the conductors which are...

Vinayak, Contrary to popular belief the IGV actuator is actually trying to keep the IGVs from opening during normal operation (during starting and loading). Air flow through the IGVs of <i>MOST</i> GE-design heavy duty gas turbines is always trying to open the IGVs--and the IGV actuator is...

GTENG, Further to the above, the issue with L4ETR1 does concern me. But, something one needs to remember is that when L4 drops out, L4_XTP also goes to a logic "1"--which drops out the ETRs. You provided some information from the Trip Log, and the time-stamps seem a little odd (in that...

RY, Yes, I did miss the word booster; my bad. But I still fail to understand how heating of the 96CD transmitter and higher than expected CPD readings could lower MW. AND, you've <i>never said</i> if the unit was operating at Part Load, or Base Load.... The only time CPD feedback affects...

Hi! GTENG, The overwhelming majority of the time when the turbine trips while testing the redundancy function, or when re-booting processors the problem is caused by incorrect polarity of the current being applied to one of the three coils of one of the servo-valves in operation at the...

RY, I didn't respond because <b><i>based on the information provided</i></b> I don't understand how a rise in CPD could cause a drop in output. And, it's not clear what effect replacing the gasket had (made the output return to near normal, or possibly even increase). Further, it's not clear...

H A R, This SRV "problem" seems to be related to this (old) thread: http://www.control.com/thread/1289667103#1402353260 So, it's been going on for a long time. And there's a very recent thread which you can use to help with this issue: http://www.control.com/thread/1413491312...

12542654/rwailikhalid, This is frustrating--I'm sure for the both of us. You are mixing two "related" but separate issues. You are overly concerned about the color of the SRV on a display, and seem to have solved that problem by changing KFSGR. The fact that you found the value different...

The 900-pound gorilla in the room (that's an English term for a very large--and visible--problem that no one is willing to admit or recognize) is that oil refiners have changed the formulations used for lube oil, beginning around the year 2000. This change was very good for improving...

Saudaslam, you're very welcome.

Dear, Usually when these kinds of problems start without some other event (lightning strike, serious battery ground, etc.) they are the result of failing power supply components. The TCPS cards in the back of each processor core (<R>, <S>, <T> and <C>) do fail over time, and some of them were...
