Central Kansas | I'll reply here to this one and answer some questions/explain for other comments as well.
This is in the early test stages. We haven't even tried testing if the auto section control will work through the AgOpenGps software because this is not working correctly. We have tried the main switch in manual mode and it does not does not maintain pressure as we turn boom valves off, and it does not work in auto either and that is where we have been doing most of the testing.
The odd thing is that it IS working to control the booms with the manual switches, just like before we started on this project, but it does NOT compensate with pressure adjustments as boom section valves are manually turned on or off. The boom section switches are wired through the relay board shown. The black wire that is switched is ground/negative. That is how this relay board's coils are switched. The way we have wired is when the boom section switches are off, it will be getting input only from the relay board. When we manually turn on the boom switches, it will energize the coil on the relay board (through switching the ground as mentioned above), and that is why we have the diodes to protect the Nano.
We have tested and retested and verified that the original SPST switches and the replacement SPST relays have the output as expected and are hooked up and doing exactly the same switching to the PCB.
The pressure does compensate for speed changes, so we know that that part is working. We plan to talk to Micro Trak today and hopefully figure out what is going on. I will post what we find out/ what was the resolution. | |
