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 37).

Press the key or 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 and keys bring the selected lift to the shift or

working positions which are defined in the rack definitions of the mounted

sample rack. The 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
