+swing, -swing – moves the robotic arm by a certain increment angle.
The sign shows the swing direction. The value of the angle is prede-
fined under Parameter >changer settings .
+rotate, -rotate – moves the rack by a certain increment angle. The
sign shows the rotation direction. The value of the angle is predefined
under Parameter >changer settings .
absolute positioning – the numbered rack position will always be
moved to, even when this is a reserved special beaker position.
relative positioning – If a numerical rack position is given with a posi-
tive or negative sign then the selected rack position will always be rela-
tive to the value of the SAMPLE variable, i.e. to the current sample
position.
Remarks
In a method sequence a MOVE command will move the lift (or both
lifts) automatically to the shifting position.
After execution of the functions +/-swing or +/-rotate the lift can be
moved without restrictions. No defined rack position is required. Thus it
is possible to cause damages if the lift is lowered without precautions.
These functions must be used with great care.
The direction of rotation is normally selected automatically by the Sam-
ple Processor. In the parameter menu under >changer settings the di-
rection and speed of rotation can be defined specifically for particular
methods.
