Single-Value Teach
With Single-Value Teach, the switching point (setpoint) is
defined via a teach point. Moreover, this is a static process,
i.e., the measurement value is constant during the teach
phase. The teach process is performed independently for
each switching point in Two-Point Mode or Window Mode.

Two-Value Teach
With Two-Value Teach, the switching point (setpoint) is
defined via two teach points. The average value of the two
teach points defines the setpoint. This is a static process
as well, i.e., each teach point is defined statically. The
teach process can be performed independently for each
switching point in Two-Point Mode or Window Mode. The
teach process is concluded with the Apply command; this
is only possible if each of the two teach points has been
taught. Alternatively, the teach process can be interrupted
with a Cancel command. All incomplete teach point pairs
are thereby lost.

Dynamic Teach (Smart Sensor Profile Spec.)
With this process, no static teach points are recorded,
unlike with the previous methods; rather, multiple
measurement values are recorded over a defined period of
time. Measurement value acquisition is started with the
Dynamic Teach SP1 Start system command and ended
with Dynamic Teach SP1 Stop. If all recorded
measurement values were in the valid detection range, the
switching point calculation is started. For this purpose, the
minimum and maximum values are determined. The
average value of these two extrema is used to form the
new switching point (setpoint). The minimum acquisition
time is 5 minutes.
