Here's a little example of how a system WITHOUT a PMS might work. (By the way--the original poster has used the terms "PMS" and "load sharing" interchangeably--they might be similar, but we have mostly been talking about frequency control, which is what we have been mostly asking about. Be...

gubavac111, The problem could be as simple as the length of time the RAISE or LOWER (INCREASE SPEED or DECREASE SPEED) command is sent to the genset controller from the PMS. It could be causing the frequency to be a little higher or a little lower than desired. This is another one (of the...

gubavac111, IF the PMS is not set up correctly AND it is trying to control frequency when only one genset is online, that could be part of the problem. Opinions--and ass-u-me-ptions--are worthless when troubleshooting technical issues, and can cause lots of wasted time and effort. If you don't...

iabose, I have seen this problem at a couple of older sites. The pipe between the generator and the L.O. reservoir/surge tank is not properly pitched (angled) to allow oil to drain to the reservoir/surge tank. This creates a build-up of oil residues in the pipe which restricts air flow...

It doesn’t help anyone to post fiction in a technical forum.

By the way, ControlsGuy25, what is the French word or term for “Droop Speed Control”? Inquiring minds would very much like to know.

Okay; so the cats procreating woke me up early this morning and I re-read and re-re-read and re-re-re-read the original poster’s comments and I understand the source of my confusion. He is referring to the yacht operating independently of shore power as a “grid”—I was confusing it as the “shore...

Okay. I gotta say something here. "Droop refers to changing the speed and frequency of the generator to proportionally change the load. That is, when the load of the generator increases, the speed or frequency is reduced by simple load feedback." This is pure, unadulterated bull poop. Pure and...

MARKlaneV, Haven't you already re-booted the processors and the TCEAs? At least on one of the units; and was it the unit that had the Diag. Alarms mysteriously disappear? When you're troubleshooting a problem like this, with multiple units, I STRONGLY recommend you write down each thing you...

HamsterKing, WOW!!! Those are some old documents; they bring back a lot of memories.... They do represent how much the Mark V has changed over the years, and it changed a LOT very quickly in the early years (as I'm sure you're aware if you have these documents). It's apparent my recollection...

GREAT Questions--and information!!!

MARKlaneV, When a EEPROM Download is performed, the information downloaded ONLY goes to a EEPROM chip in the U9 socket on the DCC/SDCC card of the processor being downloaded to. The downloaded information ONLY gets to the intended card's RAM from the EEPROM chip in socket U9 is what is...

Just a couple of things. L52B_SEL is usually the "breaker select" contact that tells the Mark V which of a possible two breakers is to be closed by the Mark V. (The Mark V can be used to close a generator breaker, as well as a tie breaker, or other breaker which connects the turbine-generator to...

andrew61, Obtaining a college degree is a sign of one's commitment and focus--regardless of the subject or field of study. That piece of paper says, "I set a long-term goal (of receiving a degree), and I did what was required in order to achieve that goal. And, along the way I did some things I...

aras.ali, Control.com has a very powerful 'Search' feature located at the top of every Control.com webpage. Just click on the magnifying glass icon. Using the search term "secondary" (without the double quotes) yielded this result (not at the top of the results; sometimes the most relevant...

Thank you for the feedback!

Jimmyco, Prior to the days of Reuter-Stokes FlameTrakkers which require auxiliary cooling the flame detectors were mounted on tubes which had manually-operated gate valves between the flame detector and the combustion can. During an off-line compressor water wash, it was customary to close...

One more thing--if you used the TMOS HMI to make the changes to the CSP segment source file, you would need to have copied the modified CSP segment source file (and the resultant compiled version) over to the <I> for the <I> to know about the change that was made. AGAIN, any operator interface...

Batch mode is just a way the developers envisioned to be able to quickly change/modify or configure I/O Configuration without having to use enter values one at a time, 'Verify Screen' and 'Save & Exit' for large changes, or even for small changes. It was not intended to be used for regular...

HamsterKing, You are correct. When you click on 'List Parms' the I/O Configurator creates an ASCII text file called IOCFG.PRM which lists all of the I/O Configuration Constants in ASCII text form. The unique thing about this file is that it can be edited and used to run the I/O Configurator in...
