External Valve Operation

External valve is used in conjunction with machines that do not have compatibility with Application Controller 1100 to control hydraulics of machine. For example, non John Deere machines that are equipped with John Deere guidance systems and an ISO connector. Ensure correct external valve is used in conjunction with hydraulic system of machine. For example, closed-center system versus open-center system. After installation of external valve and components, perform following steps for setup and operation:

1. Set machine SCV, that external valve utilizes, to continuous flow.

2. Set External SCV switch to detent.

   NOTE: Status on Implement Steer Main page now reads Ok.

3. Adjust SCV Max Flow (%) for desired performance.
