• Change of input values
• Display of current process values
• Display of current input values
• Indication of the centrifuge status
• Display of parameters
NOTE
A complete list of these commands and several examples can be found in

Positioning of the rotor
If the centrifuge is loaded and unloaded by way of a robot, special rotors
are used (see chapter 6.4.2 - "Rotors"). These rotors are positioned via an
input command.
The command "setpos n" moves the rotor automatically to the desired
position where it is then locked. During the positioning process, the
message "Posi" will be displayed in the upper area of the speed/RCF field
while a dynamic progress bar below this area indicates the progress or
duration of the process. The command that is to be executed will be
displayed in the upper area of the time and temperature field while the
lower area shows the selected rotor position.
Fig. 29: Indication during the positioning process
When the positioning process has been completed and the rotor has been
locked in the selected position, the message "Lock" will be displayed in the
speed/RCF field. The rotor is now in the correct position.
