Re: Volvo 24v alternator exciter

Mike Ondra
 

Hi Bill.

 

Thanks for this info and pictures.

 

Operationally at this point, at startup we are not getting 24v alternator output until about 2000-2200 rpm. Then backing down rpm continue with 24v output until about 1200 rpm, and below that not. I have not yet tracked the behavior of the fault light on the 24v panel in these various conditions.

 

I am still trying to understand the circuit logic for the exciter. I cannot find any circuit diagrams for this and I am not at the boat to trace the circuitry. The internet is not providing much relative to exciter theory or engines with both 12v and 24v  systems. Any insights you have on the following would be helpful.

 

  1. Since the 24v alternator is not producing 24v at startup, is the 24v alternator exciter circuit initially powered by the 12v battery (simultaneous with the 12v alternator), or by the 12v alternator after it is producing its 13.5v? There could be a design theory that the 24v alternator is excited by and only AFTER the 12v alternator is producing 13+ volts thereby reducing startup load slightly.
  2. Is it the case that the 24 alternator would be “self-exciting” after generating 24v? If so, is that “self-exciting” dependent on rpm? And if so would this relay drop out the external 12v power for the exciter?
  3. I have noticed that the alternator fault light on the 24v panel historically stayed on after starting the engine while at low rpm, but generally went out after a small increase in throttle. This probably indicates that the 24v alternator was not yet producing 24v. Is the control logic for this fault light any more complicated than that?
  4. Is the exciter circuitry independent of and unrelated to the voltage regulator?

 

Anyway, I look forward to returning to Aletes in a few weeks to pursue this and would like to be as knowledgeable as possible if you have any thoughts.

 

Thanks,

Mike

There is a relay that uses the start engine 12v circuit to close the other side of the relay which is supplied with 24 volts. That is how the "excite circuit" works for the 24-volt alternator on all model Amels that I am familiar with that have 24-volt banks and alternators. Here are a few photos:

Ken,

   That is a heartstopping event to even ponder!  I can see why you appreciate the Echo Sounder as much as you do.  One question.  Is there an alarm on this unit or do you have to be watching the screen to be alerted to a coming depth change?

All,

When I was in the Tuamotus we were crossing the interior of Makemo Atoll from the main town to the East anchorage.  We were going 6kts in 50m and we saw the reef come straight out of the blue and we were able to stop Aquarius.

If we didn't have the Echo Pilot 2D Professional onboard we would have hit.

Hello all,

I have had a good experience with the FLS from B&G which can be displayed on the B&G Zeus chart plotters together with radar, GPS, AIS, and navigation data.

I installed the sensor using the through hull of the old B&G (Hydra 2000) depth sensor which was a perfect fit. The FLS signal does not seem to interfere with the B&G ultrasonic speed sensor or the old depth sensor.

Also, I am also happy to report that I was able to install the old depth sensor to its back of it, without the need to open a new through hull, by fitting it into a water filled cylinder silicone glued to the hull.

When I installed the FLS first, there were issues with the signal and its interpretation but the most recent updates have taken care of much of it. Also, I noted that it is very important to enter the proper angle of the sensor. As we all know our SM tend to have the stern deeper in the water and that means the angle needs to be adjusted.

Once this is done, the signal is by enlarge OK unless there are waves that affect the angle of the sensor.

It is a difference if you measure the speed through water (paddle speed transducer) or the speed on ground (gps).
This difference is the current of water you are navigating actually.

Re: For Sale: S/V Adagio, SM 209 ... www.svadagio.us

Gary Wells
 

Hi everyone,

Well as some of you know Robin and I decided to pull Adagio "off the market" so to speak for a while.  While doing a demonstration a potential issue cropped up and I felt it best to stop showing the boat until it was "resolved".  So, after a lot of consultation, some disassembly and ceaning and a couple of visits by experts (with opinions and estimates) we've decided that the "issue" wasn't that much out of the ordinary.

There were also a couple of family demands which took ~us~ out of circulation for a few weeks. 

So, Adagio is back on and we are ready to move forward again if there is any interest. 

I have updated some specs on the website  (www.svadagio.us)  as we've been doing some work and upgrades along the way (most notably a new set of house batteries). 

 

Thanks to everyone that reached out to us in the past, and to Bill for his help along the way. 

 

Adagio is currently in the Chesapeake Bay near Annapolis.  Our current plan is to move South as the weather continues to cool down and eventually either round into the Gulf of Mexico or to the Caribbean for the Winter.

 

Thanks!!

Hi All, I say all because this thread has certainly created interest. We have the Interphase FLS. Like radar and  it seems many other FLS units it needs experience and interpretation. I find it useful and last year in Fiji it saved us from a serious situation. The biggest problem is surface clutter caused by the turbulence of choppy water but with experience it is possible to get useful interpretation. It needs to have all the parameters set right. In talking to other owners with the same unit it is clear that many have not persevered and have given up.

Re: Forward looking Sonar - Amel 54 - Furuno NavNet Plotter Network

Ian,
Thanks, your review makes sense, and... Very helpful to me..  I also inherited a boat with FLS (Echo Pilot), and loved it!  Knowing that your Echo Pilot made it 20 years makes me like the product even more.  Though, I must say,  the screen should never fail!  If you are sailing in the same region most of the time, dropping the hook in the same anchorages each year...  There is probably not enough value in purchasing an FLS.  But, for those owners that are planing to go exotic places, where good charts may not available, and usually anchoring in new places...  They should consider the value of an FLS.
Thanks for the detail!

Eric is correct, 
Apply a thin layer, wait a little and  and remove any excess with a lint-free cloth.
For your boat half liter is enough ( ± 15 £ ).

The results are amazing.

Hi,

Polytrol label states that the product should be applied with a lint free cloth. Wait 10 minutes and wipe off the excess. If you leave it on without wiping off the excess the deck will be sticky for months. I did not read the label and left it on in Caribbean sun. Sticky wicket to say the least.

I am investigating the possibility for using paddle speed transducer. There is Analog version of DST800 available.
