Hi
during start up of GE frame 5 ms 5002c, the start up sequence stop at 93% 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% to complete sequence and start loading FSR get trapped by start up value.
