pjkbalaji85, Open Toolbox; click on View | Reports | Alarm List. This will bring up a new window, the "Alarm List Report" window. There will be a new Menu Bar in this new window, click on File | Export to CSV... and choose a folder location to save the comma-separated file to--and remember...

Hello, PJK, Engineers are really very poor technical writers. In the case of IGVs, "fully closed" and "fully open" generally refer to the minimum and maximum allowable IGV angles during operation--including starting, acceleration, full speed operation, and shutdown/deceleration. In...

Dear Maatallah_3107, Have you looked in the GE Control System Solutions Documents folder on the HMI hard drive to find all of the GE GEHs and GEIs and other documentation for the various components and functions of the GE Mark VI turbine control system? Yes, GE make it difficult because they...

jameelrahman, I will answer a qualified yes. For decades GE used a combined SRV/GCV assembly which was manufactured for GE by Young & Franklin. GE didn't make the valve, which they had a hand in designing--but it was made by Y&F. Then, when DLN combustions systems came into prominence...

Maythem, I haven't asked about Water Injection (for NOx emissions reduction).... I assume it's not being used, but that's not a good thing to do. Does the unit use Water Injection for NOx emissions reduction, and if so, is it running during these periods of high exhaust temperature spreads...

Rajesh, Thanks for the feedback!

Maythem, A true cold spot is caused by either a reduced fuel flow-rate into a combustor (plugged fuel nozzle; non-functioning liquid fuel check valve; leaking purge air check valve; etc.), <b>OR</b> excessive air flowing into a combustor (cracked liner or transition piece; holes in liner or...

Maythem, The problem at your site is a cold spot. The highest exhaust T/Cs are 429 deg C; the lowest is 398 deg C; the "median" exhaust temperature (420.4 deg C) is closer to the highest values, and there are a couple of low values on either side of the coldest T/C value (which I deem to be...

rajesh, Each Mark VI UCVx processor has it's own internal clock, and when synchronized to each other (in a TMR control panel) they all use the same time for determining scan rates and alarms and events and such. And when the designated processor (usually <R>) broadcasts and alarm onto the UDH...

Kohsa, This model of "flame detector" seems to be a fire detector used for detecting fire (by sensing UV flame) for plant protection. It's not a traditional flame detector which is used to detect the presence of flame in a boiler or internal combustion engine for protection of the...

Barbican, Have you consulted the brushless exciter manufacturer's instructions for testing and troubleshooting? I would think proper testing shouldn't be much more than resistance tests, possibly a PI (Polarization Index, usually accomplished using a 500 V meggar), and certainly the diodes...

Tom, Finally--a question I can answer! All card configurations are contained in the IOCFG download partition that gets downloaded to the EEPROM chip on the DCC/SDCC card in <C> and <R>, <S>, and <T>. When any card is looking for configuration information it goes to the ERPROM chip of its...

What does the packager/installer say about the disparity?

ge7fa alarms, The unit-specific alarm list is rarely in the Manuals. It resides in files on the HMI used to program and configure the Speedtronic turbine control panel. If you will tell the type of Mark control used to control and protect the turbine and auxiliaries we can tell you how to...

NGdave, >You have to go to Printers and create a printer called >'Alarm Printer' (without the quotes), choose the OKI driver, >and make it the default printer. By "Printers" it is meant the MS-Windows Control Panel Printers applet where one adds and/or configures printers for MS-Windows...

Devesh, It's a variable parameter--best left untouched without a thorough understanding of the knock-on effects of changing the droop setpoint are. (They include changing the loading/unloading rates!) By convention in most parts of the world, the gas turbine for heavy duty gas turbines is 4%...

TCI handles the Alarm Printer for Speedtronic HMIs using CIMPLICITY. Although the alarms (Process and Diagnostic) are displayed in a CIMPLICITY window, it's a special AMV object that gets them from TCI. CIMPLICITY should not be used for driving the Alarm Printer. You should remove the...

nic123, I wanted to add, also, that the graphs and videos you are providing are most helpful. Thanks very much!
