• Establishes a single switching threshold
• Threshold position is adjustable using “+” and “-” buttons (see
on page 11)
Static TEACH is the traditional setup method, used when two con-
ditions 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 Out-
put OFF condition on the other (see
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 12 ).
Static TEACH and Manual Adjust
Discrete output: Using Manual Adjust with Static TEACH moves
the switching threshold.
Analog output: Using Manual Adjust with Static TEACH moves
the entire span up (+) or down (-).
Contrast Values
500+
Excellent: Very stable operation.
100-500
Good: Minor sensing variables will not affect sens-
ing reliability.
32-99
Low: Minor sensing variables may affect sensing
reliability.
0-31
Marginal: Consider an alternate sensing scheme.
