Angular adjustment of the crucible holder shaft couplings
Again in this procedure, the instrument must be turned on.
1.
Remove the crucible holder middle section.
2.
Enter the “Special parameters” window on the interface, by clicking on the
padlock icon at the bottom right of the screen, and enter the code 2206
followed by ENT.
3.
Set the REF ("reference") twisting correction parameter value to 31°.
4.
Press U and wait for motion to complete.
5.
Then press REF button and wait for motion to complete.
6.
The anti-twisting post of the
left
side collar should be close to or touching the
mold bracket. If not, loosen screw E and F and rotate the collar until they
contact, without any lateral motion.
7.
If the anti-twisting post of the
right
side collar is not close to mold bracket,
manually force the rotation of the former until it hits the mold bracket.
8.
The ant-twisting posts must be as close as possible without touching the
mold holder brackets. The post that is closest to touching will determine the
angle to use. Increase or decrease the angle to obtain the best result.
9.
Then, to verify if the REF parameter is optimally adjusted, press the “U”
button and wait for reset operation of the crucible holder to complete, then
press the “REF” button. The crucibles holder will rotate towards the back and
stop at the set REF angle. In this position, the anti-twisting posts mounted on
the left and right orange collars must be in the closest position possible
without touching the mold holder orange brackets. (One side may exhibit a
larger gap.)
10.
If one of the posts hits or touches the bracket at this stage, then the REF
angle will need to be decreased, and the preceding step needs to be re-done.
11.
Press the “SYNC” button to verify that 3 full bumps are executed on both
sides. This is what one wants when holder is perfectly aligned (not twisted),
but sometimes, the number of bumps can be lower, or uneven between right
and left sides, in which the REF parameter needs to be increased.
