In this configuration, the switch output will be open when the process pressure
is within a user selectable range and closed when the pressure is outside of these
boundaries. This is designed for applications where there is a known acceptable
operating pressure range.

Windowed, Normally-Open
In this configuration, the switch output will be closed when the process pressure
is within a user selectable range and open when the pressure is outside of these
boundaries. This is designed for applications where there is a known acceptable
operating pressure range.
In this configuration, the switch output will be open for pressures less than the
selected setpoint. The switch output would then be closed for pressures greater
than the setpoint.
