Dear Friends,
The ratchet problem observed in one of our GE frame-VIB gas turbine few days back is the 33HR switch toggle to state "1" immediately at start of ratchet cycle. Normally it should pick up at the end of forward cycle approx after 12 seconds start of the normal ratchet cycle. But due to early pick up of 33HR within 2 seconds of the L20CSX and L4HR, the ratchet cycle terminates premature.
Please inform possible solution to the above mentioned problem.
Thanks,
