Hi
during start up of GE frame 5 ms 5002B, the start up sequence stop at 84% hp speed and can't reach 95% to stop bleed valves and auxiliaries of start up. we noticed that FSR value taking start up value which is the min selection value rather than acceleration value which was min and used during warm up. when the acceleration value become greater than the start up value by 0.2 which is sufficient to make the turbine reach 95% . This problem is showen after major inspection of the turbine . I tried to adjust FSKSUAR value from 31.7 to 36.7 this allowed me to start the turbine but affter a shutdown and restart of the probelem is still exist
