If a Swing Head drive is mounted with a 6.2058.020 adapter in order to
use racks smaller than intended, then the axial distance must be modi-
fied in the configuration of the control software. The corresponding data
can be found on the accompanying sheet of the 6.2058.020. The axial
distance refers to the distance of the swing axis (see figure) and of the axis
of rotation (middle point) of the sample rack.
2.4 Sample racks
A sample rack is a turntable that acts as a receptacle for sample vessels.
Various types of sample racks are available for different numbers and
types of sample vessels.
The 864 Robotic Balance Sample Processor requires sample racks with up
to a maximum of 48 cm diameter.

Other user-defined racks can be supplied upon request and the required
rack data can be loaded and configured in the control software. Any
arrangement of rack positions is possible.
Magnet codes
Every single sample rack can be unambiguously identified by means of a
magnet code. The Sample Processor can thus recognize automatically
which rack is in place.
When replacing a rack, this should first be returned to starting position
using the Rack initialization function (see "Manual Control" in the con-
trol software). This will enable an unambiguous recognition of the rack
