1.3 Sensors
Beaker test
Front view
Each tower of the 760 Sample
Changer is equipped with a
beaker indicator to detect the
presence of a beaker in front
of the tower. This infrared
sensor detects many different
materials, if any object is
placed in correct position. This
beaker test is carried out after
each MOVE operation.
Magnetic rack code indicator
The magnetic sensor for the
detection of the individual rack
codes is mounted below the
sample changer's turntable.
The magnetic binary code of
the racks can only be read, if
the rack is in initial position
and therefore the magnet
holder is in accurate position
right above the rack code in-
dicator. For this reason the
760 Sample Changer should
be initialized by or
turned off and on right after
every rack change.
