Patent attributes
In a proportional solenoid valve control device, a mode selecting switch has an auto-mode position for sending a control signal from a level converting section to a driving signal amplifying section, a valve fully-closing manual position for supplying a valve fully-closing signal to the driving signal amplifying section, and a valve fully-opening manual position for supplying a valve fully-opening signal to the driving signal amplifying section. With the mode selecting switch set at the valve fully-closing manual position, a value of the valve fully-closing driving signal can be adjusted. With the mode selecting switch set at the valve fully-opening manual position, a value of the valve fully-opening driving signal can be adjusted. This makes it possible to easily perform an initial setting operation of the proportional solenoid valve by a valve controller.
