Teach-in

The detailed procedure for teach-in is described
on page 21.
The factory-set null point and end point are replaced by a
new null point and end point. The null point and end point
can be set separately, the output gradient changes.
Steps
► Move magnet to the new null position.
► Read new null point by pressing the buttons.
⇒ The current end point remains the same.
New null point

► Move magnet to the new end position.
► Read new end point by pressing the buttons.
⇒ The current null point remains the same.

► The curves can be inverted by actuating the button.
⇒ Inverting inverts the curves of both outputs. For
example, a rising curve for output 1 is changed to a
falling curve and a falling curve from output 2 is
changed to a rising curve.
