(saturated
can be presented by the user. The sensor locates a single sensing threshold (the
signal)

condition on one side, and the Output OFF condition on the other (see Figure 2).
The first condition taught is the ON condition.The Output ON and OFF conditions can
be reversed by changing Light/Dark Operate status in SETUP mode.
