Two-Point Static TEACH (Threshold)
•
Establishes a single switching threshold
•
Threshold position is adjustable using “+” and “-” buttons (see
Manual Adjust)
Static TEACH is the traditional setup method, used when two
conditions can be presented by the user. The sensor locates a single
sensing threshold (the switchpoint) midway between the two taught
conditions, with the Output ON condition on one side, and the Output
OFF condition on the other.
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 (see
on page 8 ).
Static TEACH and Manual Adjust. Using Manual Adjust with Static
TEACH moves the switching threshold. The lighted LED on the bar
graph will move to exhibit the received signal, relative to the
switchpoint.
