First thing to do is check the Servo currents. That's going to tell you pretty well what is going on.

You need to be reading your GE maintenance manual.

Looks like you are in big trouble here as you obviously have no idea how your system works. Do you have GE manuals? You have 2 Alarms " IGV position Servo Fault" This means that there is a fault with the Servo. "IGV not Following" The IGVs are not following the Control Setpoint (probably...

Thanks for the info. Looks normal Has this machine run on Liquid fuel recently? What is the Fuel Gas Temp. and what is the Gas Dewpoint?

Although this not a mechanical forum, Can I ask a few questions to try and understand more. 1) How many hours does the machine have? 2) Do have pre-shutdown data, particularly Wheelspace Temps. 3) What fuel do run on? Do you use Liquid Fuel?

Remember it's quite a complicated system. You have two separate O/speed systems + a lot of hardware verification. Overspeed has got to be totally 100% reliable and has got more and more complicated as each Mark version arrived. It also has got to allow the removal of the mechanical Overspeed and...

Can you give us a bit more info? Did the IBH work OK in the past? Was any maintenance done on the machine recently? Can you give us the logic for the alarm "Bleed Heat system not operational" that kind of sounds like your problem.

From my experience of Frame 5 machines (46 years) it is absolutely no way common to experience high vibrations on start-up, in fact the Frame 5 is probably the most rugged and reliable machine that GE ever built. Possible mechanical causes: Imbalance caused by failed or reduced cooldown. This...

I don't know where you are located but in a lot of locations this would be totally against safety regulations. I guess that if you could design some sort of password protection then maybe you could get away with it. I completely understand what you want to do to allow Operators to Nitrogen...

TNH is pretty simple.It is a 60 tooth wheel so 60 pulses per revolution converts to RPM or %age speed. Fuel flow is a bit more complicated. Again there is a multi-tooth wheel giving pulses/revolution, but there will be a control constant which converts this speed to fuel flow. I don't have...

Do Have MKVIe manuals? Post your Email and I can send you a few documents.

Firstly I don't have manuals or drawings available to me right now. I was hoping you had but, from your questions, it appears that you don't have either. You are obviously new to Speedtronic so let's get some basics clear first. All Speedtronic has Control and Protection and they are two...

If you have a MKVIe manual it will explain all. But, remember you have 2 x Overspeed Protection (Control & Protection) + Hardware Failures.

The answer is nothing really. Why do you think it should cause a problem?

Can you give some more details on the "bad results" and how long has the oil been in service? This will help for us to advise you on replacement procedure. Check your manuals, there is a lot of detail there on Lube Oil system.

There are various companies who provide MKV Training, try Googling around, I'm sure you can find them.

Hi Bill, Just got back from a job overseas. Now my brain is out of work and out of jet lag, I've been reviewing your problem again. A question, what is Plant MW Control and what is it doing? If IBH is modulating of course it will change MW as it is trying change Inlet Air Temp. but I see you...

Hi Bill, I have a Control Spec. for a recent Frame 7. It is a mechanical drive, but the TTRF temps should be roughly the same. Drop me an email to [email protected] and I'll send you a copy.

I would need to see your system to be sure, but you maybe could bypass the eliminator and temporarily vent to atmosphere. get the vent as high as you can, it should help the leakages by venting the LO tank pressure a bit. You could also arrange the vent so you can remove the eliminator and fix...

Hi, the GE performance monitoring package is very expensive, but good. It pretty well depends on what your needs are. You can do it yourself by running your machine, preferably at Base Load once a month or every two months. What you need to do is set up a spreadsheet in Excel, enter the data...
