Any alarm/trip has been annunciated /dipslayed before or during the shutdown ..

Where or which points did the staff/team investigate on troubleshooting this issue.. Are you suspecting a Mechanical or Controls systems failure...

Related Why the gas turbine exhaust gas temperature gets higher value in startup then its back to normal? There are two significant EGT rises in a jet engine start up before it stabilises with other engine parameters. The engine start up begins when the pilot selects the engine mode selector...

Exhaust temperature spread is calculated by a combustion software which determines the spread limit and the first, second and third spreads. All of them, are used in determining the alarm and the trip for the gas turbine. First spread is the difference between the first maximum thermocouple...

Any improvements on this case /issue...

I suggest you to have a read on this interesting attached here article/document

It can be also a combustion problem

High exhaust spread can be dangerous and damge the GT ... It can be due to some friction on the Hot gas path elements like blades ..turbine wheels...

There is an allowable spread on GT exhaust temperature ... There can be an alarm and a trip if Exhaust spread is above a designated /fixed level ...

Try the GSV (Get system values) function block see if can catch something over there

Do you have FDT (Field device tool for profibus troubleshooting) and DTM (Device Type Manager software ) I think that you can solve this issue with those tools! You most welcome Cheers James

Ok so its another thing that you mentionning DCS faceplate is not same as Auma devicenet or display... Can you operate the Auma by local mode?? Looks like the problem is with remote mode even problem can be from DCS link to the Auma ..Maybe Profibus issue

I understood clearly, what the OP was looking for ... You misunderstood my thread... I wrote these quotes to tell OP that there are OEM STANDARD PROCEDURE FOR ACHIEVING what is looking for... I asked about LCI and he just replied Yes... My post was also to telling him to ask original packager...

Thats not the place to track this XMIT SUSPENDED SIGNAL NAME ...You shoud ask GE Belfort for better assistance ..

Check EGD (Ethernet Global Data ) That can be done through Toolbox control ST...there is a document on how to check live datas of EGD .. By the way did that unit tripped due to the P0 XMIT SUSPENDED ALARM/TRIP SIGNAL... OR Unit still runing? Check also the ETHERNET switches...

Yes sure check UDH ? PDH too

Hummm seems that something is not operating correctly on the ETHERNET DATA HIGHWAY ..

Here some notes from GE9FA Installation guide: 3.14 ALIGNMENT OF GENERATOR–TO–TURBINE, COLLECTOR ASSEMBLY AND TURNING GEAR–TO–GENERATOR (MLI 0411) Alignment will be performed as described in GE document “Basic Field Alignment Instructions” (MLI 0411). Alignment readings will be witnessed by...

By the way Original poster did not confirm if Unit has been built by GE Belfort or BHEL... I am sayin that cause BHEL got an erection procedure where it described Preliminary and final alignement and references to the ML Drawings and other Procedures/Instructions .. Here some notes from BHEL...
