6.12 Teach-in of the measuring range
The start and end points of the curve (Slmin and Slmax)
can be defined by teaching in to indicate the gradient
progress and gradient value of the curve.

Within the original linear range and at least
1.1 mm (BAW M12MI-BLC35C-S04G) or
2.3 mm (BAW M12MH-BLC70G-S04G) away from Slmin
The teach-in process has no time limit.
The minimum distance from start to end point:
– BAW M12MI-BLC35C-S04G: 1.1 mm
– BAW M12MH-BLC70G-S04G: 2.3 mm
The start point Slmin is initially saved temporarily and can
then be overwritten any number of times.
If the target leaves the measuring range during
teach-in, the error message
TEACH_STATE_ERROR is shown.
If the measuring range is changed by teach-in, any
previously saved switching positions (BDCs) are deleted.
The new curve offset and gradient value set by teach-in
can be read out as described in Tab. 6-7 on page 12.
