According to OEM manuals: If the sub module is missing then replace the sub module on the device If sub module is present then check for malfunction of submodule ( loss of field power, hardware failure...) Check on RX3I Profinet controller manual page 102 as there are all recomm&andations to...

According to OEM manual this kind of LED status is indicate the power supply has failed and is no longer supplying sufficient voltage to the backplane... Always glad to support you ! James

Thanks for clarifying ! You mean backplane not backpane... I will check how to know how gonna clear this fault.. By the way you still need to check if there is kind of watchdog or diagnostic report...

It looks like this issue is related to the Profinet scanner ... Will have a better read on the OEM manual it helps a lot!

Good day Any diagnostic alarms or other error code/message associated to this syst fault...

I have a Root cause analysis on some GE HDGT like Frame5/6 B/F/9E... We can learn here more on that case ..

How many thrust bearing on Load gear box ...1 or 2 can you share a scheamtic/drawing..

What about "axial displacement" did you checked it....

Okay , Will be lookin to these details.. Do not forget that it is a "load gear box" ....so search first the origin of the problem before to know what to do ( changing a bearing ...you should explain it clearer ..as you mentionned that "tooth damaged"... We do not know about plant operations...

What ia msayin is that , There could be others reasons than bearing and how to solve the problem can be different... Did the unit experienced any abnormal vibrations ...

Changing bearing can be solution but we do not know about origin of the issue... Can you be more specific/better explanation on how this happened... Is that some work have been done prior to this event...

Hi Azer, What you mean by "trust " are you meaning "Thrust"... What is Unit OEM /type/model

Hello, It would be great to know the plant configuration.. Did you at least checked /troubleshoot by reviewing the Application programm/software... If not you can post here a draft /skecth of the program so we can review it and give you better advise... Since on Gas turbine some unit do not...

Hi Pauldh, Thanks for these clarifications....indeed that will not going to work properly in medium/long time operations.... There is according to OEM documents solution on that skid design with drain & control/stop /regulating valve ....installed with manifold only ... You can try to ask you...

Did you heard about backlash compensation... Have a read on articles /documents on this method ...it can hekp you !

Thanks Pauldh . I will have a better view on this thread ..then come back after speaking around my colleagues about that design from GEEPE Belfort ... I know some people from GEEPE ( Iam in Belfort right now..) who can advise on alternative solution if youu are not happ/satisfied with that...

IF "wheel " move faster then torque will decrease ...

Hello Looks you are no more worry about NOx abatement... values on your unit But more worry about this Flow divider in the water steam injection... By the way is that "SYSTEM " also used for both steam/water injection...( just for information) For sure there is other way for designing such...

Speed Regulation and Percent Slip The squirrel-cage induction motor has very good speed regulation characteristics (the ratio of difference in speed from no load to full load). Speed performance is measured in terms of percent slip. The synchronous speed of the rotating field...

Starting Current When a three-phase, squirrel-cage induction motor is connected across the full line voltage, the starting surge of current momentarily reaches as high a value as 400% to 600% or more of the rated full-load current. At the moment the motor starts, the rotor...
