Beaker positioning / Turn
rack
The MOVE command can place the current sample or a special
beaker in front of tower 1 or 2 (if present) by rotating the rack. An
absolute rack position can also be specified.
During method processing a MOVE command can run the lift or
both lifts to the shift position.
The turning direction is automatically chosen by the changer ac-
cording to the predefined changer setting. In the Parameter Menu
under '>changer settings' the turning direction and speed can be
defined specifically for each method. These can also be modified
in a sequence with the corresponding 'DEF' command.
If there is no beaker in the rack position chosen, this is recognized
by the beaker sensor.
The changer reaction to a missing beaker can be predefined in the
Parameter Menu under '>changer settings'. The alternatives
available are halting the processing and issuing an error message
or selecting the next rack position. For more information about this
see page 90. If a special beaker is missing, processing is always
halted.
LIFT
9
LIFT >sample sequence
3 LIFT: 1 : rest mm
1,2, ∗ work,
rinse, shift,
special, rest,
0…325 mm
Positioning the lift
Raising or lowering one or both ( ∗ ) titration heads to a defined po-
sition. Work, rinse, shift and special position are rack-specifically
defined in the Configuration Menu under '>rack definitions'. See
also page 38f. These parameters can also be changed in a se-
quence using the corresponding 'DEF' command.
The rest position is the zero position (0 mm) of the respective lift
i.e. the upper stop.
Each lift can also be precisely positioned to the millimeter. The
LEARN function is also available for this purpose. See also pa-
ge 50.
