Well, I wouldn't say we're friends just yet. Acquaintances, yes; colleagues, likely. Friends, well, don't you think that's rushing things? In any case, I'm now more confused than before. So, as for your concern for my health, I have something of a bigger headache now, thank you very much...

It's absolutely possible to get the download information from any Mark IV (non+ or +). But if you're NOT doing a migration, then it's not necessary to have the data downloads from the Mark IV. As long as your drawings are 100% accurate and you provide all the Control Constant printouts and...

Are you trying to understand how the servo valves work, or how the valve actuators work, or what the symbols on the drawings mean, or how VH5 works? This is a huge question, and if you can narrow it down, or we can work on it one piece at a time, we can try to help.

I've started to reply a couple of times, but I can't really understand where this switch is mounted. Is it on the gas turbine axial compressor or on the gas compressor which is driven by the gas turbine? I can tell you that when flame is lost, the gas turbine axial compressor discharge...

Denice Thomas, You posted another question about gas valves, so this question must be about why AA pressure remains above CPD when the unit is running on gas fuel. There are two basic reasons. Most Frame 6B units have an accessory gear-driven AA compressor, and it runs all the time the...

Dear, Congratulations on finding the file. You've hit the limit of my knowledge on this task. I'm wondering if you have a Mark VI<b>e</b> and not a Mark VI. If so, then you would likely have an HMI configured with WorkstationST and ControlST, and not TCI. In that case, the IE links, though...

My, you have a lot of requests. There are a few inconsistencies (Surprise!) in the Mark V's handling of I/O. You need to use ALL of the available documentation, which includes the I/O Report (TC2KREPT.TXT) and the Signal Flow Diagrams in Appendix D of the Mark V Application Manual...

Is the unit at your site a single-shaft heavy duty gas turbine, or a two-shaft heavy duty gas turbine? What kind of control system is in use on the turbine at your site? Is the control system SIMPLEX or TMR?

A former colleague just sent me a CONFIG.DAT from a hybrid HMI (don't ask!). I'm pasting what I believe to be the relevant lines here. But, if this is a new unit installation, you should contact the packager/installer and have them help you with making this standard function work! I'm only...

I want to caution anyone about this procedure!!! The CSP should be automatically changing the Control Constants for these tests. However, there were some early Mark V's that were shipped with CSPs which didn't do the switching properly, so a workaround was necessary if the sequencing wasn't...

Increase the scavenging flow rates.

F:\CONFIG.DAT is an ASCII text file, and you should find it in the SITE folder, in the "E:" drive on most new HMIs. It can be opened/edited with Notepad or Wordpad, but you MUST save any changes in MS-DOS format (not Word or RTF!).

Okay; now I'm confused. BB started this thread, and sd added his problem. We haven't heard from BB in a while, and now BB is posting again. BB's last input was on 15 Nov, and he stated they were awaiting two new 20TU solenoids with higher max pressure ratings, and that the unit had been...

You can find any number of people who can provide an interface to the Mark V and the Mark VI for displaying data values on any. What you can only find in one place, that I'm aware of, is a Mark V interface that can fully and completely replace the Mark V operator interface. The Mark V and...

When you are testing an over-speed trip (electrical or mechanical), the "maximum search speed" is set to 113.5%. This is to allow the turbine speed to be increased above the trip set points (see below). Although I've never tried it, I believe that if, during an over-speed test, the turbine speed...

Has this option ever worked? If so: <b>What has changed?</b> I believe it might be something as simple as checking the options section of CONFIG.DAT to make sure that the HMI logging option is turned on (if I correctly interpret the message you seem to be saying is displayed when you try...

rab, Congratulations on getting the unit back on line! Thanks for the feedback! "Feedback is the most important contribution!" (c) and is what makes this forum as valuable as it is to the Speedtronic community. I don't know of any specific recorders, but if you do a web search you will...

Digital turbine control systems, particularly those for steam turbines, require some very high-speed processing capability. That's because steam turbines can overspeed very quickly and easily. One should choose a digital steam turbine control system with the above thought in mind. Having said...

This question was answered a couple of years ago. I would have liked to refer you to the previous post, but I couldn't find it. The respondent said that the designers used electrical motor frame size as the basis for the designation. I always think of a "frame" gas turbine as a heavy duty...

You have not provided nearly enough information for anyone to make an educated response to your post. <b>When did the problem start?</b> After an electrical storm? After a loss of DC power? After a loss of AC power? After an AC power surge/spike? After an attempt at making application code...
