    GE LM6000 Controls Upgrade Help

    Many of these older LM6000 systems were a split architecture controls, the GE 9070 sequencer with separate Woodward Micronet or GE Mark VI purpose designed fuel controller "PLC". A redundant Ethernet link glued them back together. It is better to combine all the functionality into one control...

    LM6000-PG Speed Switch Fail to Close

    The safe-set logic compares the NSD turbine speed sensor to the Generator Keyphaser speed sensor in the Bently vibration system. A difference greater than 150 RPM for 10 seconds triggers a No Motored shutdown independent of T48 temperature in this case, because potentially something is failed...

    GE LM6000 PG VBVs

    One more thought is to check the PS3 instrumentation sense line for loose fittings or water in the line ... possibly if accidentally not isolated during a water wash.

    GE LM6000 PG VBVs

    * On this system you would have dual redundant controller cards that current share. * When one LVDT, one card, or one side torque motor fails the other card takes over. * The Woodward servo (HSU) on the gearbox has 3 torque motor coils for each VG loop. * For simplex cards two coils are...
