3.3 Auxiliary switches and positioning signals
The illustration below shows the relationship between the angular rotation, the
adjustable switching points for auxiliary switches A and B, and the positioning signal.

The setting shafts for the auxiliary switches turn together with the adapter. The scales
thus only refer to the inner mechanical 0° limit.
