Cedar Rapids, Iowa | Do you have more detailed specs on the levers that control this? Are they potentiometers?
I'm in the process of building an auto-steer system for tractors, and part of my research has brought me to the Sauer Danfoss PVG32 valves, which can be controlled by a potentiometer. Basically there is a pot that has one end connected to ground, one to 12vDC, and the wiper sends a voltage to the valve controller. When the wiper is centered (6vDC), it is in neutral. Move the wiper either way (increase or decrease voltage) and it will move the spool in the valve, which would make the machine move. It basically says 50% of the system voltage is neutral.
To control two of those side by side is going to be an interesting adventure. The problem is that you actually need to control both levers as separate controls. One has to move forward while the other moves back, all with electrical signals. | |
