Yikes ! I just googled the LM 2500, they are super high tech. I bet a very small vibration in that turbine power plant would be a huge concern at however many 100,000's of RPM's that things spin at. My little MEP-831A that I just bought little single cylinder Yanmar diesel is along ways from...

I've moved forward with the MPU route, I believe in the KISS method and I know they work well and will be very easy to install. I did consider a optical RPM sensor but I could not find one that had extended operating temps, just 0-to something Celsius with a operating voltage of 10-30 VDC...

I think this is the correct part number for the ring gear for the Yanmar L70AE series and I counted 97 teeth, I counted once but it gets us close to the count. I think the MPU with the 7310 controller will work fine. I ordered the MPU so we will soon see.

You brought up a great point so I just spent working that out buy considering a optical non contact RPM sensor where we could put a small reflective strip on the flywheel. I looked at the manual for my controller and realized it mentions a maximum frequency of 10,000. Calculating the engine...

Thanks Guyfang, you are absolutely right. As we say in the electronics industry "RTFM". I've chased my own tail so to speak by not starting from the beginning. We all want to help and forget about the simple stuff.

I've talked to the tech support people and have decided to install a MPU to read RPM and its $40. Its 2 wires and drill a 3/8 hole in the sheet metal flywheel cover. I'll take the recoil starter off and then the flywheel cover to determine the best location for the MPU...

:o You are so right ! I was just thinking that. Its pretty cold here and the 831A is the only one I can get in my garage so I thought I'll start with that one. I'll keep on trying to figure it out with all the help from the knowledgeable people here.

Excellent point, well I haven't dug into this yet but if there is no rpm signal (controller can count flywheel teeth) then it maybe my only option since there is no actual oil pressure.

I thought about this some more and since its just a sense signal what do you think about pulling the freq from the hot on the back of the convenience outlet then we dont have to worry about before after the contractor. I've used the freq to stop crank before and it works really well. The only...

Thanks again, here's some screen shots of the controller software. Would you mind giving your opinion on what input would work best for the engine crank stop. Thinking this thru a bit more I guess I'd have to use the freq from the input to the contactor.

Your right, I posted incorrectly, what I meant was 60Hz at the output lugs and thats why I listed under the RPM that its not needed because its a Inverter type gen-set and the RPM does change with load. Come to think of it isn't a Inverter type gen head a DC generator then converted to a nice...

I forgot to mention if your like me I would take a couple of pictures to make sure it all goes back together again correctly presuming it was wired correctly from the git-go. :)

Ok Folks, here is how I'm going to program and configure the controller for the MEP-831A. I'll do it first then the 802A/803A. engine data and controls draft Input/output programmed type -Oil pressure 831A has binary oil/low oil...

I would disconnect the "transfer switch" which might be a generator parallel synchronizer to sync 2 gensets and I'm not sure but it maybe that device works on the 120/240 configuration. Have nothing on the output lugs and turn on the contractor then measure with the 2 probes from your meter set...

It's a good day, I found the 2 controllers !! I'll power them both up today and make sure the firmware is at its latest so we can all get going on this little adventure. Watch the video about the remote alarms, control and monitoring these controllers can do. I want this function so if I'm...

Make sure the genset is off then open the control panel and cycle the 120 120/240 switch lots of times. That might be all it takes. I dont think you have the VM-AM switch set for 120V 1 Phase, it should be at the 5:00 position I think.

I considered the smarthings a year ago but will look it again and likely switch myself. Like I've mentioned I've installed these controller a few times so I think we will have no troubles. The manufacturer makes a range of controllers so you have a controller that has just auto start or Mains...

That would be great!! I have a wink but I also have 2 Linux servers running here with 100 MB speed. I'm not a software person and would really appreciate any help in that regard. I'll purchase the RS232-ethernet gateway and put the system online if you want to login and work on that. The...

They are great controllers, I have had them working in a wooden box on the ground in nasty winter blizzards. They were connected to chinese LP generators. I want the remote monitoring and control capabilities these controllers can provide. Thats why I'm pursuing this. I just picked up my...

I have all the TM's and will be figuring out the wiring as best as I can, I'll likely need some help though. I have wired these controllers into Generac and Honda gensets. These autostart panels are great, I'll be able to see fuel level, engine temp, RPM and lots of other parameters. They are...
