    DLN1 TTRF1 low during Premix Transfer - Ext. Lean-Lean

    Sorry for the delayed response. The 7EA units here have an Auto-Tune software that does not revert back to baseline GE tunes between runs. The previous run on this machine was on a roughly 50 deg F higher temperature day. The unit had ran for several days with that cooler automatic tune. One...

    DLN1 TTRF1 low during Premix Transfer - Ext. Lean-Lean

    After some additional guidance, I was able to check the partload curve and it was set just a bit too cold. All 4 points were raised roughly 15 degrees and we were able to get through transfer into Premix. Thanks again for all of the suggestions.

    DLN1 TTRF1 low during Premix Transfer - Ext. Lean-Lean

    2001 7EA units here. These units have Mark VIe Migrations from 2019. No diagnostics during the attempted transfers, only Modeless for a moment, re-igniting Primaries, and flashing back to Lean-Lean Neg Mode until it times out to Extended Lean-Lean. This TTRF issue of not continuing to raise...

    DLN1 TTRF1 low during Premix Transfer - Ext. Lean-Lean

    We were able to find a fairly substantial leak coming from two of the can to CDC flanges on #4 and #9. Checking torque values on those can bolts today. Looking through the past trends from the past attempts, the flame detectors were operating properly along with gas valve demand vs feedback...

    DLN1 TTRF1 low during Premix Transfer - Ext. Lean-Lean

    Hello. I was able to close the purge valves and pressure test the space between them with 80psi. The pressure held for quite some time. For the SRV, looking at the trend during startup and transfer, FSGR was smooth, opened proportionately with P2 pressures, and matched the other units in...

    DLN1 TTRF1 low during Premix Transfer - Ext. Lean-Lean

    Hello, it has been a while. In normal operation on the other 3 GE 7ea Gas Only Simple Cycle units on-site, the TTRF1 would raise through 1950 deg F on up past 1985 deg F through the transfer to Premix Steady State. The other morning during a cold start (<20 deg F), one of the units here was...

    Integrating Fuel Totalizer into Mark VIe

    CSA, Thanks for pointing me the right direction. The Instromet Flow Meter is sending an output of 0-5V per their manual. As I am looking through the GEH-6195F I have here, it appears that my time and resources may be better placed with bringing a 4-20mA output into the Mark Ve. *...

    Moog or GE Part Number

    MOOG #:G772K240 Type: S38FOFA4VB4 GE #: 312A6077P003 I cannot speak to your 312A6077P001 Servo. If you look at the servo nameplate, the type and Moog numbers are often listed.

    Integrating Fuel Totalizer into Mark VIe

    Hello, I have an INSTROMET Q.Sonic-3 Ultrasonic Flow Meter that was commissioned in 2001 with shared outputs to the Gas supplier and my site, the end user. The outputs at the gas yard are scaled in 0-20ma for their use. I receive a PULSE that is equivalent to .50 MCF/hr. This PULSE signal...
