L4DE, L69DE in MARK VIe Gas Turbine
L4DE, L69DE variables in Frame 5 gas turbine with MARK VIe
By Chiranjeevi on 13 May, 2017 - 8:36 am


can you tell about the above variables for frame 5 turbine? and brief about DE start up sequence logic?

Hi, Chiranjeevi,

Was the Mark VIe provided with the unit when it was new, or was the previous turbine control system upgraded to a Mark VIe?


Please post the L4DE and L69DE rings.
