Pressing on the "- / +" button will be used to set an angular position, to be set
where a rotation limiter touch lightly. This will be useful when installing new
crucible holder shaft couplings.
The "REF" button rotates the holder to the offset value set in the REF field. That is
how the user can confirm whether the offset is right or can be further fine-tuned.
The "SYNC" button starts the actual anti-twisting motion, so that one can
ascertain that the action is done correctly. With the correct adjustments, three
distinct knock sounds should be heard.
Offsets
The middle left section is used to adjust the various mechanical motions.
Tilt loading
This parameter controls the tilting of the crucibles holder to facilitate the manual
loading and unloading of the crucibles.
Rocking offset
This is used to fine-tune the verticality of the "reset" position (i.e. when the
crucibles' openings are all upwards, ready for filling).
Increasing the parameter will cause the crucibles to reset to a position where their
openings point away from the user.
Oppositely, decreasing the value will cause the crucibles to reset towards the user.
When used in conjunction with the twisting correction, this parameter should not
be outside the (-40 to +40) range. If other values need to be used, then a
mechanical adjustment of the crucible holder is required.
Sliding front offset
This offset controls the position at which the holders slide outside the furnace, to
the front. Typical value is around 5000.
Increasing the value will cause the holders to stop later, closer to the user.
Decreasing the value will cause the holders to stop earlier, away from the user.

NOTE: The complete adjustment procedure is described at page 74, Angular
adjustment of the crucible holder shaft couplings.
IMPORTANT: None of the parameters below is actually memorized until the
user presses "SEND".
1.
Enter the desired value using the "- / +" button. (Katanax recommends
setting for this parameter at 20°.)
2.
Press "SEND" (vertical button) to transfer the parameter to the motor
controller.
3.
Press "U" to order the fluxer to move the crucible holders in loading
position, at your set angle.
4.
Test if this angle is convenient by inserting a crucible in the holder, and
fine-tune the parameter if needed.
