I bought the EC-AGS+ from Cummins and it sat on my desk for several weeks. My 10kw Onan model # 10HDCAA Spec A on a 2003 Beaver is not listed in the compatibility chart. I called their Tech Support and one guy said it wont work and he didn't seem to be to knowledgeable about any of it. He really didn't even know about the new unit until I told him about it. I didn't return it (although I generated the return) just on his word, not wanting to give up, I called another Onan tech guy a couple weeks later and he (who also didn't seem to be too knowledgeable) wanted me to call a guy in Indiana because he thought that one might know how to retro fit it. I called and left a message and never heard back.
Please note, the EC-AGS+ pairs with every Onan generator, with the exception of the Onan QD3200.
I emailed the gentlemen mentioned in the Press Release above; Karl Wilson. In the letter I expressed my concerns as to whether the EC-AGS+ would function on my generator 10HDCAA since my gen wasn't listed as compatible per the compatibility chart located in the owners manual. He was extremely responsive and wrote me back that evening. He explained he would find out and let me know. The next morning I awoke and found he had sent an email explaining there may be a couple quirks, but that basic operations should function as advertised. Monday morning I went to work. The unit is plug and play. What complicated my install was the generator slide in\out and wire harness routing to verify bundle positioning during movement at either end. Also the mounting of the gateway in a place that would allow the correct bundle positioning. It took me awhile to make that decision.
- I took the old unit out the EC 30 W which someone had basically tie wrapped in there.
- I then verified the new AGS would plug right in and it did.
- I removed plastic wire sheathing from the old harness, cleaned it up and installed on the new.
- I then began routing the harness following the basic same route back as the old unit, in the image the Y harness connectors are visible next to the generator cabinet. I ended up having to tuck these connectors behind the conduit for clearance on generator slide movement.
- I attached to the conduit piggy backing all the way back.
- I searched for the best mount location for the gateway unit and finally settled on the outboard forward side of the passenger frame rail. This location had relatively easy access and good location for harness slack/ movement. I drilled 2 small pilot holes making sure of clearance behind and then 2 larger holes for the mounting hardware and mounted it there. Drilling those frame rails was no easy task, slow and careful all the way.
I finally routed power ground, red/black, crimped terminal lugs the correct size for the studs and wire (18g). Carefully attached to the studs, and the unit powered up. I later found out from Karl I should either cap and stow the gray wire or hook it to chassis battery power so the AGS can monitor that as well. Parameters can also be set to power the coach if chassis battery falls out of values, I think....
The AGS powered right up and I downloaded the app from google play store and connected via bluetooth and paired my phone to the gateway, doing some basic set up along the way model ID, log in password. I also paired to the temp sensor to the gateway via the app and I later mounted in the coach near the thermostat. Once I completed basic set up I was literally able to start and stop the generator from my phone while in the manual mode I did this several times being careful about short cycling.. When I paired the temp sensor I could monitor coach temperature from the phone. (EDIT: ALL THIS VIA BLUETOOTH)
I labeled this my forward zone and there is capability to add 2 more zones.
The AGS has many capabilities while in the auto mode. I ran out of time and light and put the toys away. I left the unit in manual mode so there will be no auto starts while in storage, just yet. I will need to go down through the app while paired to the gateway and set up those parameters.
