shyam, You are most welcome! Thanks for the feedback, also. 'Feedback is the most important contribution!'(c) here at control.com. It is what distinguishes control.com from a lot of other Web-based forums. When posters who receive assistance from responders on control.com provide feedback...

All, I'm not really clear on the problem. If the transducer is original equipment or an original equipment replacement (same manufacturer) and is labeled--or the documentation lists the output as--as 150 mv/IPS, that's the value that should be entered in the Mark V I/O Configurator for that...

shyam, Okay, so part of the mystery is solved. L2TVX1A is assigned to an output of <P> core, which explains the L2TVX1A_REF (the Mark V uses the _REF signal as a check to see if the output has, in fact, been energized--or de-energized--when commanded). I don't have access to a Mark V...

G.Rajesh, A jaw-type clutch, such as is used on many Frame 6B machines, will stay engaged after cooldown when there is no hydraulic closing pressure via 20CS-1 <b>IF</b> the jaw clutch teeth are "sharp" and not rounded off by forced closing when the turbine shaft is still turning (which MANY...

pascal, Mark V's don't have TRLY cards; Mark VI's and Mark VIe's do. The "standard" for discrete outputs for all digital Speedtronic turbine control panels (if adhered to by designers and field people) is to use a separate logic signal name to "drive" an output and NOT to use contacts...

Dhinesh, I'm a FIRM believer that Internet forums are for the benefit of many people, and rarely take discussions off-line. I've been rightly accused of providing too much information at times, but that's because a LOT of people read these posts over years (those who use the 'Search'...

SHYAM, The Mark V I/O Report will tell you precisely which software logic signal name drives the spark plugs. The file, found in F:\UNIT1, is named TC2KREPT.TXT. It is an ASCII text file and can be opened with MS-Notepad or MS-Wordpad, and you can search the file for "L2TVX" to find all...

Joe, One more very important clarification. I don't think your RTD is failing if the feedback from the RTD "seems" to be spiking when the motor is started. The "spike" is caused by induced voltage in the low-level signal cables/wires. The likely cause of the induced voltage is the in-rush...

Dhinesh, You need to ask: 1) Your local and national regulatory agencies (industrial safety; code bodies; etc.) 2) The company that insures the equipment at your site 3) Your site safety manager/supervisor (though it's pretty much guaranteed they will not question whatever the...

Joe, If the shielded cable is run in the same conduit with the motor leads, there's not too much more that can be done--unless there is some kind of "filtering" on the Huber that can be used to kind of smooth spikes. In-rush current can be high, and is likely to cause problems if the...

Elvin Aponte, Actually, I'm not really clear about what you've done and how you're doing it. I've read and re-read your posts and I'm not exactly clear. I've seen some of these GEI's (GE "Informational") documents. Some are better than others; most are not very good. They seem to have been...

Dhinesh, The fear of a gas leak and the potential for an explosion and/or fire is probably the most important reason.

Elvin Aponte, Based on the information provided, if you are able to set the Processor ID of the new EEPROM with the LCC display, then the chip is fine and the communications between the LCC/SLCC and the SDCC are okay. It seems you can't "access" the <R> processor from the operator interface...

Rishi Kumar Srivastava, If the Mark VIe is a recent upgrade from an older or different control system, could it be that no one ever knew the jaw clutch halves separated with the older control system, some time after "...stoppage of scheduled ratcheting...."? There is usually a spring to...

Mrinal, Sorry, I have no mathematical formula(s) for such calculations.

FSX, Did you specifically ask GE to provide Aux. Hyd. Pumps that could support continued operation in the event of loss of pressure/flow from the Main Hyd. Pump? (If so, GE has not really responded to your request for quotation....) From the information provided the only reason I could...

Elvin Aponte, Hmmm.... My next thought would be there's something wrong with the DCC/SDCC or the DENET between <R> and <C>. Or the chip was inserted wrong or is bad. Does the LCC/SLCC display show that the processor has accepted being told it is <R> when it is displaying A4? Or does it...

FSX, I presume the reason for installing the Aux Hyd Pump would be to prevent the need for cranking the turbines when stroking/calibrating fuel valve- and IGV LVDTs? Do the MS5001P units have "bang-bang" (two-position; open or closed) IGVs or variable (modulated) IGVs? Do the MS5001P...

When replacing a EEPROM chip (or a DCC/SDCC with a new EEPROM chip) it's necessary to use the LCC/SLCC display keyapd to tell the chip what the processor ID is (<R>, in this case), and what the StageLink ID is (if the DCC/SDCC or U9 chip is in <C> or <D>). Next, FORMAT the EEPROM in <R> with...

Mambo--and mhwest, Thanks for the explanations and clarifications! I continue to learn from the experience and knowledge of others here at control.com--which is what makes this site so useful to so many people. Thanks, again!
