How To Replace and Improve the Sea Ray Systems Monitor

[ttmott]

ttmott - What did you do about the engine alarms? I forget which you went with G2 or the Albacombi, something else? But do you use that for SW alarms or did you hard wire the over temp/low oil etc to something else?

There were never engine alarms on the SR Systems Monitor for my boat. The closest thing is a generator shut-down alarm. All of the engine data and alarms are through the Diesel View or Vessel View (which ever you have) via Smartcraft. In my case the NMEA 2000 integration with the Vessel View 7 enables engine and systems data on my Garmin MFD's as well as the Vessel View 7. All engine data (pressures, temperatures, fuel, etc) are on the NMEA 2000 network from the Vessel View 7 and can be displayed on all of the boats monitors (Garmin and Maretron). Take a look as the schematics in earlier postings.

Yep I get it, I wasn't thinking, you have QSM11's. Mine are a lot older, detroit 6v92's, all analog along with my system monitor that displays the over temp alarms etc for the engines as well. I am using a G2 for that conversion, or was until it was fried this past weekend by a bad alternator. And I am thinking of going with an OceanLink 7, but that doesn't cover engine alarms from analog sources, only from SW limits. I guess I am going to add another RIM100 for that.

I have read through and saw what you posted. Very nice job, very well thought out.
Here is my schematic on THT. https://www.thehulltruth.com/11382347-post40.html

I posted my trials and tribulations of converting the Detroit's over to N2K. Full thread here https://www.thehulltruth.com/marine-electronics-forum/881525-chetco-digital-sea-gauge-g2-2.html

Hi Tom, Question on your use of the Maretron NBE100 - the network bridges. I see you are using two of them. I get the need for one leading to the bridge possibly, but not the 2nd one. Were you seeing dropouts in the data stream or was that just a precaution?

I am asking this because I am seeing data dropouts witht he Actisense I am using and am considering adding one of these. My network doesn't exceed the limits and in fact is only about 50% of what the limits are. So just curious as to what you are seeing as our networks are very similar. Thanks.

I didn't install them to extend the networks; all network runs are within the NMEA 2000 guidelines without the NBE100's. The NBE100's are installed to help avoid voltage surges over the total network due to lightning and other electrical surges. In discussions with Maretron during the system design they recommended the NBE100 as it is optically isolated. I learned a lot as a result of the lightning strike the boat was involved in last year.

 

[Skybolt]

Ah Yes Lighting strikes ... I can understand why you installed them for that, I too experienced one of those about ten years ago, thank goodness it wasn't with this boat though. That's right about the time I learned about bonding and the do's and don'ts and how important they are.

I just found this great thread, my interface module is dead and I would like to use this system to replace it. Would I use the RIM100 module to monitor oil pressure and coolant temp alarms just like the original or is there a more appropriate module?

 

[dtfeld]

This is the schematic for a 2001 410, and should be pretty accurate as to what is hooked up to it. Not all inputs are present on every boat (these where used on multiple models/engines combinations). You will need to go into your bilge and find out what is there and map it to the RIM100.

PM me and I can get you this file.

 

[Captain Brian]

Thanks! I have the schematic and it looks like if I want everything mapped I would need 2 of the RM100 modules and would wire them into the NMEA2000 bus I have in the boat. Can the DSM410 be programmed to read that many inputs/alarms? Great info and thanks for the reply!

You need to read this entire thread to fully understand what Tom did. But engine related things like oil pressure and coolant temperature can not go through the RIM100. The RIM100 is a status device and can tell you what is on or off like bilge pumps, lights and engine alarms. Although the engine alarms are not qualified NMEA 2000 engine alarms, they are, when connected correctly only status if a switch is triggered or not. Also in order to view any of the RIM100 outputs you need an NMEA 2000 display capable of viewing PGN 127501, like the DSM410 from the same company, Maretron.

To view things like oil pressure and coolant temperature you need and analog engine translator that translates the analog data into NMEA 2000 PGN 127489. Which can also be displayed on the DSM410 along with a host of other NMEA 2000 information.

EDIT: Yes you can have as many of the same type device as you want with NMEA 2000, up to 252 that is.

 

[Captain Brian]

Skybolt, thanks. I miss spoke, I am not looking to view the oil pressure etc. through the system I am looking for it to set the alarm when water temp is too high or oil pressure is too low just like the original systems monitor did.

Thanks again

No worries, you can absolutely do that, just understand those alarms are not going to alarm on an MFD and only on a display like the DSM410. That said it works quite well and using two RIM's is not an issue.

 

[Captain Brian]

Fantastic! Thanks for the help!

 

[ttmott]

I believe the 410DA had engine water temperature, engine oil pressure, and gear temperature switches. So, I think a total of 11 discrete channels are required to include the generator oil pressure and the 4 bilge pumps. Each RIM100 is six channels.
There are no issues with multiple RIM100's in the system you just need to set each as a different instance. I would set up the DSM display pages as one six line for the engines and another for the other systems.

The bilge pumps need to reference to ground
The generator needs to reference to the generator's B+ Ignition
The engine switches (which I think go to ground in fault) need to reference to the appropriate B+ engine ignition.

So I am somewhat of a wiring rookie but looking at the previous diagrams does this look accurate? Also looking at the systems monitor the trans temps supposedly do not go to it... After wiring this up any hints on the setting in the DSM410 module to acknowledge when these set? I admit I have not studied the DSM410 manual yet. Please note I will need fuses but did not show them.

That looks like it will work just fine. The only thing I would suggest is have all of the B+ either on odd or even terminals so easier to remember. My engineering sense of order.....

Yep, looks real nice. Take a look at the Blue Sea fuse panel for the ignition feeds.

Your best bet with the DSM410 is to get one and play with it configuring the screens in your favorite chair and a cold one. It has a lot of features to get to know.

One bit of advice I can offer for the RIM100 and the DSM, is to use the labels in the RIM100 for the names and set the DSM to use the labels. That will save years of scrolling to set a name. You will also need a USB100 or IPG100 if you want to be able to use N2KAnalyzer, which you will need to use at some point. Although the DSM will allow configuration by itself.

This may be a stupid question but, is there a way to use this kind of system to replace the old "Boat outline" style monitor with the red led's? Mine has never worked. I'm sure all of my sensors are analog. I have carbed gassers (another obstacle) and my current Garmin MFD's are NMEA 0183.....

Certainly that system can be converted!
Those lamps in the "Boat outline" monitor are triggered by something coming on or going off. The channels in the Maretron RIM100 are triggered on or off the same way. You will have to install a NMEA2000 backbone and a Maretron display to view. The NMEA0183 can't be adapted to work with the Maretron equipment.

The RIM100 is looking for the presence/absence of voltage from 9-240 AC or DC, so I would think you could easily replace the old LED pad. The easiest way to set this up and monitor it would be to use a Maretron DSM410 display. It’s NEMA2000 only.

You can get a NEMA0183 to NEMA2000 gateways, and that might get you some info on your MFD, but there can be limitations.

The pic is what sits were my old LED sys monitor use to sit. If you trace the ribbon cable back to it's origin there should be a terminal block that has all of the signals on it. Pretty much what @dtfeld posted, but in a terminal block form factor.
