Special beaker positions are predefined places on a sample rack that are not 
treated as sample positions. They can be occupied by rinsing beakers or 
conditioning beakers and selectively addressed during a run sequence. Up 
to 16 special beaker positions can be defined per rack. For each spezial 
beaker the work position of the lift (tower 1 and 2) and the beaker radius can 
be set, see above.
