Teach Process
For a successful teach-in as well to directly set a setpoint,
the following conditions must be met:
– The setpoint that is to be taught must be in the validity
range of the measurement value signal.
Additionally in Two-Point and Window Mode:
– Setpoint 1 must be greater than setpoint 2.
– The distance between the setpoints must be greater
than or equal to the minimum hysteresis.
Due to the requirements listed above, it may be
necessary to vary the order of the setpoints for a
successful teach-in.
An active teach process is indicated by illumination of the
red LED. If the red LED flashes, the currently pending
measurement value is outside of the validity range (IO-Link
process) or a manual teach was not possible.
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.
