Abstract: A valve switch unit has a detector configured to detect an input, such as current, from a machine controller. The valve switch unit also has a switching circuit configured to switch control of the one or more valves an automatic controller to the machine controller if the input from the machine controller exceeds a predetermined threshold. When the current detected exceeds the predetermined threshold, the circuit switches control from the automatic controller to the machine controller. In a similar fashion, when the current falls below the predetermined threshold, the circuit switches control back to the automatic controller.
