Each carousel is moved by its own cylinder. Every cylinder has a sensor, that sense and report
the actual status of the respective carousel (see Operationmanual: Form –
Controller
). The
carouselsensors are small black boxes fixed at the cylinder by a screw. For proper working of
the sensors during analysis they should be adjusted at the middle of their working area.
Next to the sensors each cylinder has two chokes, that can be used to regulate the speed of
lifting up or down of the carousels.
The cylinder of the crucible-carousel can be reached from LHS and is located behind the
carouseladaptor. Its sensor is provided at the left side of the cylinder.
The cylinder of the lid-carousel can be reached from the RHS and is located next to the
carouseladaptor. Its sensor is provided at the frontside of the cylinder.

The adjustments for both sensors are analog.
c.)
To adjust the sensor open Form
Controller
at the software TGA. At
Inputs
the
actual status of the carousel is been shown. Please make sure that the carousel is
lifted up (
Inputs:crucibles up
marked respectivly
Outputs: crucibles down
not
marked), by deactivate
Outputs: crucibles down
if necessary.
d.)
Loosen the screw that fixes the sensor at the cylinder until you can move the
sensor.
e.)
Slide the sensor slowly upwards until the mark at
Inputs:crucibles up
disappears.
At the point were the marking disappears the detection area of the sensor ends.
f.)
Mark the upper boarder of the detection area.
Please note:
If there is no mark visible (
Inputs: Crucibles up
) before the adjustment of the
sensor it is completely outside of its detection area. In this case move the sensor upwards or
downwards until you see a mark at the software and follow instrution from e.).
g.)
Now move the sensor downwards (the mark appears again) until the marking
disappears again. Mark the lower border of the detection area, as well.
h.)
Site the sensor nearly at the middle of the detection area and fix the screw again.
