Use the correct type of switch for the necessary limit and
reference switches (see section Fitting").
When selecting the sensors, note that the accuracy of the
switchover point of the sensors determines the accuracy of
the reference point.
You must make sure that the switchover point always lies
within a step resolution.
The following diagram shows as an example the connection of
the sensors.
