khairi, Specifically: What is the problem you are having with the IGVs on your MS5001 GE-design heavy duty gas turbine with a Mark VI TMR control system? If you tell us the problem you are having, there might be a solution or an explanation that will prevent having to stroke the...

Sanjay, We like the word 'question' instead of doubt (check you Oxford's and you'll see why), and to answer your <i>question</i>, no; you won't affect any other parameters or operation if you change it. Again, it can only be changed by some operator clicking on RAISE- or LOWER SPEED/LOAD...

Sanjay Solanki, It's most likely that someone has disturbed the Isochronous speed reference: TNRI. It should be 100.0%, and it can get changed when someone tries to adjust the load on an Isochronous machine by clicking on RAISE- or LOWER SPEED/LOAD. (It's not possible for an operator to...

H A R, Also, has someone removed the cover from the side of the base on which the combined gas valve assembly sites to look at the actuators to see if there is a plug on the top of the SRV actuator cylinder? This can be done while the L.O. Pump is running, but it can be noisy and there...

Neo, I'm not quite sure what the question is, but let's try this. The comparator is checking to make sure the median value of CPD is greater than 35 psig; if it's not then when the unit is above 14HS and running (we'll get to that in a minute) then L3TFLT is a logic "1" and usually, these...

sriram surya, Without being able to examine the application code running in the Mark VIe of the turbines, it's very difficult to say what has been done or why. I can say for the gas turbine, it's not generally typical that generator control automatically shift from VAr or PF control to...

shyam, The turbine has to be shut down, off cooldown, and the Mark V has to be powered down--to be completely safe when replacing this card. Also, some Mark Vs had CTs (Current Transformers) connected to the <P> PTBA and if yours does, then you have to short the CT circuits to prevent a huge...

H A R, As for the formula, if FPKGNO is negative and the formula is (TNH*FPKGNG)+FPKGNO it's the same as if FPKGNO is positive and the formula is (TNH*FPKGNG)-FPKGNO. The Belfort Bunch is at it again!!! AAARRRGGGHHH!!! They are such bloody idjits!!! (Usually, FPKGNO is a negative value...

shyam, Simply because AutoCalibrate is not configured is not a reason to use the Demand Displays for stroking devices--particularly for the SRV. ACALIB.EXE should be in G:\EXEC directory; if it is, you have the software tool portion of the process. When this file is run (executed) either...

H A R, I don't speak French, and the translation programs I used didn't help with understanding the alarms. (Basse is 'farmyard'???) Post is 'after' and 'allumage' is ignition, so something is tripping the turbine after flame has been established--but there's not enough information to be of...

KHAIRI, I'm beginning to be VERY distressed by all of the issues you are raising. If the battery charger was not provided by GE or the packager of the turbine and auxiliaries there is a very good chance that it has an internal battery ground detection circuit. This is VERY BAD as it will...

The hydraulic actuator(s) for the SRV (and GCV) of a combined gas valve assembly (and you STILL haven't told us if the gas valves are combined in a single cast steel assembly or not!!!) are single-acting cylinders (pistons). As such, there are rings which are supposed to prevent hydraulic...

KHAIRI, Battery ground alarms have been covered several times before on control.com. (There is a 'Search' function cleverly hidden at the far right corner of the Menu bar at the top of every control.com page. It's highly recommended that you use the Search 'Help' first.) The Mark VI is...

shyam, or SHYAM, I would highly recommend that you NOT use the Demand Display for stroking the IGVs, SRV and GCV--particularly the SRV, because there are I/O Configuration settings for the SRV which must be changed prior to using the SRV Demand Display and then changed back after using the...

shyam, or SHYAM, The configuration you are describing is not typical, so without being able to see the schematic drawings for the circuit it's very difficult to say for sure what might be the problem. And I'm not clear if there is second, physical relay that's connected to <P>, or if it's...

SHYAM, Geiger-Mueller flame detectors are polarity sensitive devices, meaning that the 315-335 VDC applied to them must be connected positive-to-positive and negative-to-negative. If they are connected backwards, nothing untoward will happen <b>UNTIL</b> the detector sees a high-intensity...

Neo, I've been having computer hardware issues with my old and trusted desktop--which is the computer I use for writing the long missives for this thread. (It's too difficult to respond to this thread using a tablet--I don't have a keyboard for the tablet.) I'm still keen to continue--and...

Does the 9E have DLN-I combustors? What kinds of gas and liquid fuels does the unit burn? Is the gas considered low-BTU gas fuel? How recently was this unit installed and commissioned with these firing speeds? What comprises the starting means? An electric induction motor and...

Khairi, You are asking for someone to teach you something that is usually taught in a classroom setting--and which costs tens of thousands of US dollars. And by World Wide Web. There really is NOTHING like digging in and learning for yourself--and if you have specific questions you can...

Hello, KHAIRI, or khairi, I don't think you can see or monitor the earth (ground) resistance using Toolbox, unless there is a new power monitoring block. However, you should be able to monitor the battery supply voltage of both the positive and negative legs of the battery supply with...
