CSA.
Very glad to receive your reply,and thank you sincerely for your engagement.I am not rich,or i am willing to pay you for this interesting journey
And if you are busy,just let me know. You know waiting is miserable.
I hate to quit and i wanna to go on this journey and finish it.
Thank you again for your help.

You missed this question below:

A>B----|
| L14HSX L3TFLT
---------| |---------||-----------( )
</pre>
A=CAKCPD(35psi)
B=CPD
L14HSX=Auxiliary signal to L14HS
And i tried to find the differebce between L14HS and L14HSX.<pre>
L14HS L4 L14HSX
---------||--------------||-----( )
|
L14HSX L94X |
------||------|/|----
L94X=Startup check stop GT normal shutdown;
L14HS=HP operating speed signal;</pre>
As for L3TFLT,if CPD is less than 35psi when gas turbine is under normal operation,then L3TFLT is logic 1.
I was wondering the function of the L14HSX,and whether can L14HSX in the L3TFLT rung be replaced by L14HS.
I am confused about L94X.In the toolbox, its description is :Startup check stop GT normal shutdown.

L3RS1 L3RS2 L5VPRO_LATCH L3RS
-------||----------||------------|/|----------( )
L3RS1=Startup check stop ready to start 1;
L3RS2=Startup check stop ready to start 2;
L5VPRO_LATCH=Protective VPRO card trip-latch;
As we just finished L3RS1,i think L3RS2 is my assugnment this time.

L3COMM_IO=VCMI state changes for <R>,<S>,<T> OK;

</pre>
L3GFLT=Gas fuel control fault;
L3LFL=Liquid fuel control fault;
L84TL=On total liquid fuel;
L84TG=On total gas fuel;
L62TT2=startup check stop mutiple start counter;
let me start with L62TT2:<pre>
Timer_sec _Counter
L2FZ(log_in) (log_out)L62TT-----------L62TT(INC) (AT_CNT)L63TT2
K62TT(pu_del) K62TT2(MAX_CNT)
L1XY(RESET)</pre>
L2FZ=startup check stop multiple starts permissive;
K62TT=startup check stop multiple start time delay(5s);
L62TT=startup check stop multiple start and atuo refire;
K62TT=startup check stop multiple start count(2);
L1XY=startup check stop aux to master contr-stup perm;
When the number of pulse(L62TT signal) is less than 2(K62TT2),than L63TT2 is logic 0.
There are several combinations which will make L3ACS logic 1 when L63TT2 is logic 0:
1.L84TL=1,L3LFLT=0; The gas turbine is on total liquid fuel,and the liquid fuel control is not in fault.
2.L84TG=1,L3GFLT=0; The gas turbine is on total gas fuel,and the gas fuel control is not in fault.
3.L3GFLT=0,L3LFLT=0; The fuel control system is not in fault.
CSA,I am confused about L62TT2,and can you explain it briefly.
According to the above combination,the gas turbine can start up when one of the fuel control systems is fault,and is it reliable?
