The sample rack can be rotated by a certain increment independ-
ently from a rack position with the function +/- rotate.
The robotic arm can also be swung by a certain increment inde-
pendently from the position with +/- swing.
The values of the rotation and swing increment are defined in the
device properties of the tower and of the Swing Head respectively
(see Section 3.10.5).
• Beaker test action: If no sample is present at the rack position
that has been moved to then the action selected here will be carried
out, provided that the beaker sensor has been activated in the rack
table (see Section 3.10.5).
• Options: The shift rate and the shift direction can be edited
here. The swing rate defines the rate of the robotic arm when mov-
ing to a rack position, a special beaker or an external position.
4.12.2 Lift (LIFT)
The lift can only be moved when the USB Sample Processor is at a
valid rack position. In manual control "--" indicates that the lift is at an
invalid position. This is the case, for example, after a manual rack reset
(see Section 3.24.6).
• Tower: The selected lift position is moved to by the selected tower.
Both Tower 1 and Tower 2 are always available for selection, even if
your USB Sample Processor only has one tower.
• Lift position: In addition to any lift position in mm the freely de-
finable positions Work position, Shift position, Rinse position and
Special position can be selected. These settings apply for sample
positions, each special beaker and the external positions. The lift
positions are defined in the rack table in the Device manager of the
USB Sample Processor (see Section 3.10.5). However, they can
also be assigned directly in the manual control of the USB Sample
Processor (see Section 3.24.6). A lift height of 0 mm corresponds to
the "Home position", i.e. the lift is being located at the upper stop
position. Please ensure that no lift position exceeds the maximum
stroke path defined in the device properties of the tower.
• Lift rate: The rate at which the lift is moved can be edited here.
4.12.3 Pump (PUMP)
The PUMP command is used to control the pumps mounted on or con-
nected to the tower of the USB Sample Processor.
• Tower: This is the tower at which the selected pump is to be
switched. Both Tower 1 and Tower 2 are always available for selec-
tion, even if your USB Sample Processor only has one tower.
• Pump: Selects the pump that is to be switched. With "1+2" both
pumps will be switched at the same time.
• Status/Duration: A pump can be switched on or off, or switched
on for a certain time.
