assembly notice: the left horizontal axis should be installed
according the following principle.
If replacing CCD unit is needed, install two vertical CCD units
first.
then find out the triangle start mark on the encoder disk
edge(circled in the picture). This mark point at the position of
the start code of the encoder.
As shown in the picture, keep the telescope left status when final assemble. Gently rotate the disk though the
left horizontal axis to connect it with the telescope. One hand fix the telescope and the other hand rotate the
disk gently and aim at the screw holes between the body and telescope. Be sure that the triangle marked on
the disk must stay nearby the lower vertical CCD. This is very important. If the position of the disk is not
right the instrument will display false vertical
angle information.
When finish the step above, tighten
setscrews and do not forget to reassemble some parts such as
gasket.
Step 6: Vertical CCD Unit
Refer to step 1, 2 and 5, take off the left cover, angle main
board and vertical absolute encoder disk, then remove the 4
setscrews circled in the picture. Take off the vertical CCD
unit and remove the other CCD unit by the same method.
Keep CCD properly.
