8.10 Sample changer commands
726 Titroprocessor, Instructions for use 186 186
Value
Numerical value of alteration or allocation
0…1…999
The numerical value of how much the SAMPLE variable
has been altered or what value it should be allocated
can be freely selected (whole numbers).
MOVE_S
Position current sample beaker
The command MOVE_S can be used to position the current sample beaker
in front of tower 1 or 2 of the sample changer.
The rack is rotated so that the beaker position of the rack, which corre-
sponds to the contents of the SAMPLE variable (see above) comes to rest
in front of the tower given in the command. Rotation of the rack is only pos-
sible when the lift (or both lifts) are located on or above its rotation position
(see LIFT command below).
After the racks has been rotated the corresponding beaker sensor checks
whether a beaker is present in this position. If this is not the case then the
procedure defined in the beaker test mode (see page 184) will be carried
out.

MOVE_S Sample to Tower 1
Sample to tower
Rack rotation target
1 | 2
With a 2-tower changer the target of the rack rotation
and thus the positioning of the current sample beaker
can be selected at will. In this way it is possible to sub-
ject the same sample to different processing steps at
two work stations during a method run. For example,
these could be two different titrations or more compli-
cated sample preparation steps.
MOVE_B
Positioning special beaker
Up to eight special beakers (rinsing, conditioning beakers, etc.) with perma-
nently assigned rack positions can be defined for a single sample rack. The
command MOVE_B can be used in a method run to position a special
beaker in front of either of the changer towers.
Rotation of the rack is only possible when the lift (or both lifts) are located on
or above its rotation position (see LIFT command below).
