|On this dialog, you can also invert the meaning of the electrical signal by checking the Invert box for either or both Pins. In this example, because we have the Invert box checked for both Pin signals, their respective functions will be activated when their signal is electrically OFF.
Note that the Invert function works similarly for the output signals. If Product on Zone is selected as a function, with the Invert box checked when the zone is occupied, the electrical signal will be OFF. With the Invert box checked, when the zone is clear, the electrical signal will be ON
