setting for this feature is 1%, meaning that any signal below 1% will drive the valve to a fully
saturated condition to achieve the best shutoff possible.
The High Setpoint is the value of the input command signal above which the positioner will
stop following the command signal. Normally this limit is set to 110% so it is not activated.
The only reason that a valve is normally saturated open is for a 3-way valve that must seat
at both ends of travel. The illustration at the bottom of the page is a graphical
representation showing how the soft limits work.
