4.4.1 Sample rack and lift functions
For safety reasons it is not possible to rotate a sample rack if a lift is in a
lower position than the specified shift position. This is why it is important to
determine the correct sample rack definitions with great care (see page 38).
Press the
<PG UP> key or <HOME> before the sample rack is to be
rotated.
If a sample rack is used which has not been designed for parallel
processing with a two-tower changer model (M14-0, M16-0, M19-0 …) then
a rack position must be correctly aligned in front of the particular tower so
that the lift can be operated. This is done by marking the target tower and
then rotating the sample rack to the left or right with the corresponding
softkeys.
Move lift
The <PG UP> and <PG DN> keys bring the selected lift to the shift or
working positions which are defined in the rack definitions of the mounted
sample rack. The
<HOME> key brings the lift to the rest position (0 mm
position) at the topmost position of the selected tower. In order to move a lift
millimeter by millimeter the [Lift up] and [Lift down] softkeys
should be used.
Move beaker to absolute position
As well as the possibility of rotating the rack by one position (softkeys
[Shift left]
and [Shift right]) a particular beaker position which
is to be placed in front of a tower by a rack rotation can be entered. Press
the [Shift to pos.] softkey to carry this out

Which beaker is to be positioned in front of which tower can be entered
here. Press a softkey to rotate the rack in the corresponding direction.
[Shift
