Did your lube oil pump remain on for the cooldown period, i.e 24 hours?

Well, I am not sure about that. Examining the last attachment of GEH-6721G, it appears that the TBAI card is provided for the exact function of sharing single 4-20mA signals across all 3 controllers. Also if memory serves there were specific I/O cards for HART, but I'm not sure that's your...

If you can use the existing EEPROM, U9 from memory, match the and hardware jumpers on the new card. I don't believe you should need to download anything. BUT I could easily be mistaken.

So to clarify a few points. You are using a single transmitter(loop powered) to feedback on all 3 processors?

Have you checked the Burdening Resistor on the QTBA card for R?

I'm assuming you have wired the Transmitter in series through each Processor I/O card?

The card may not download the IP address, the processor will not boot.

Mite pay to replace the batteries on the UCV(X) card, often soldered on to avoid this issue in the future.

Can you use your Bentley software(System 1) to get the trend from the keyphasor speed compare to all your speed inputs on the low speed shaft, they should be in your trip log. I believe if the safeset had sheared you would be getting zero generator speed. Likely it looks like a faulty key phasor

Hello Byron, No problems, I have the literature your after including the training manual from GE. Send me you email.

Check the operation of IGV dump valve 20TV-1

Assuming your unit is using the MKV for synchronisation. Set up high speed trending for DV, DVX, SVL and SVLX. DVX and SVL are for display purposes. See which is erratic

which manufacturer? there are slight differences

Hello Dustin, From memory and please its been a while. I seem to remember when they started trying to use the Pentium machines even GE had an issue. Was your existing HMI a Pentium of 486 machine?

There are numerous conditions that can cause increase in GCV position. From compressor condition, air filter condition, ambient temp, IGV position etc.... The FSR is either temperature or speed controlled. The controller is driving the valve to a position to maintain either required speed or...

The Manufacturer for the unit? As Controls Guy and WTF have mentioned there are different configurations for the MV Cubicle dependent on manufacturer. Some units have doors at the top of the NDE of the generator accessible from the outside, normally scaffold required to access. This is where...

Have spare parts if your iterested?

Normally you ned to contact HIMA to do this.

Loss of AC power, can failsafe to ratchet mode. Depending on your controls configuration.

Hello, Are the accelerometers on the same section of the engine but at the 4 and 6 o'clock positions(AFT looking FWD)? Measuring the voltage wont help, you would probably need a decent meter to see the variations in signal. Couple of things you can do, without the correct test equipment. Put...
