3.6 Robotic arms with beaker sensor
For safety reasons, the presence of a beaker on the sample rack of a Sample
Processor can be detected. Some robotic arm model versions are therefore
equipped with a beaker sensor.

principle
A robotic arm with beaker sensor is mounted as described on page 16. The
connection of the sensor cable must take place while the instrument is
switched off.
The beaker sensor is automatically recognized when switching on the instru-
ment.
Functioning of the beaker sensor
If the beaker sensor of the robotic arm is activated, then the lift of the Sample
Processor will move automatically into its work position after a MOVE com-
mand. The presence of the sample vessel is checked by the robotic arm
setting down on top of it.
