730 Sample Changer, Introduction 47
Moving the lift
The keys <é> and <ê> allow upward and downward movement
of the lift on the tower that is currently active. The lowest possible
lift position is defined by the configuration parameter 'max. lift
way'.
HOME END
The <HOME> key runs the lift of the currently active tower to the
rest position (0 mm), i.e. to the upper limit.
<END> runs the lift to the predefined work position.

LIFT With the LIFT command, the lift of the active tower can be run to
a given position. In addition to selecting an exact position in mm
(0 - 325 mm), the <SELECT> key can select a predefined position
(work position, rinse position, shift position, special position, rest
position = 0 mm).
Example:
LIFT : work <ENTER>
LIFT : shift <ENTER>
LIFT : 150 mm <ENTER>

SAMPLE The <SAMPLE> command serves to set the current sample posi-
tion. It defines the first sample beaker for the subsequent sample
series.
Pumps
PUMP
4
The PUMP command controls the 1 or 2 pumps that are acces-
sible on the active tower – for rinsing the titration head and for
aspiration of sample or rinsing solution. Maximum 2 pumps can
be operated simultaneously. The pump command switches the
selected pump on or off, according to the current state. The cur-
rent state of the pumps is shown directly in the display.
Example (Tower 1):
PUMP on/off no. ? <2> Display: PUMP -+-- (+=on)
PUMP on/off no. ? <2> Display: PUMP ---- (–=off)
Pump 2 on tower 1 is turned on and off.
Pressing <STOP>, all pumps (and stirrers) are switched off.
