from the GE Gas Turbine department...
GE Frame 9Fe Gas TurbineI am working with GE Frame 9Fe, Mark6 gas turbines. Who can give me a complete list of Trip and shut down conditions of the machine?
If possible send it to the mail <hanifrk @ yahoo. com>

There is no list of trip and shutdown conditions for GE-design heavy duty gas turbines; every unit is different. If anyone wants to know what conditions result in a trip or shutdown of the unit(s) at their site, they need to refer to the sequencing and logic for the unit(s) at their site; in you case that would be found in the Toolbox files of the Mark VI Speedtronic turbine control system.
Anything that can trip the turbine drives logic signal L4T; so if you start at the rung for L4T and work backwards from there you will discover every condition that can trip the unit(s) at your site.
If by shutdown you are referring to any non operator-initiated condition which results in an automatic unloading and fired shutdown of the unit, all of the conditions will drive logic signal L94X. So, find the rung for L94X and start working backwards and you will discover every condition that can initiate an automatic shutdown of the unit(s) at your site.
Self discovery is so much better than having others do it for you.
