Proceed as follows to check the chain tension:
1.

Press a number of crucible trays in the back row down ( 1 ) to hold them in
their current position (see Fig. 11: Crucible chain).
2.

Move the front crucible trays ( 2 ) to the right and left (see Fig. 11: Crucible
chain). The crucible trays should have approx. 1 mm of play.
NOTICE
Blockage
Incorrect tension

Excessive tension can lead to a blockage when the crucibles are moved
by the motor. If the chain has too much play, bent elements on the chain
can block the cogwheel support. A chain play of approx. 1 mm should be
maintained (see description above).
Proceed as follows to adjust the chain tension:
1.

Release the screw ( 1 ) on the underneath of the sample changer platform
(see Fig. 12: Adjusting the chain tension).
2.

Move the screw ( 1 ) to and fro to adjust the chain tension (see Fig. 12:
Adjusting the chain tension).
3.

Check the chain tension again.
The chain tension has now been adjusted.
