1. Remove the power supplier protection cover.
=REMARKS=
To prevent from the short circuit inside the
power supplier, be sure to cover with the
insulating protection sheet to the power
supplier.
2. Turn the power [ON] and return to origin.
3. Move the SY axis to 200mm.
4. Attach the magnet stand to the camera axis.
5. Touch the dial gauge at the left reference surface
on the fixed rail guide (the position where 2mm
from within the rail guide and 45mm from the left
side).
6. Zero the dial gauge.
7. Check the height from the X axis LM guide
attachment surface to the rail guide upper
surface.
=Specification=
Height : 349.05 to 349.10mm
=HINT=
Be sure to use the height measuring jig. Be
sure to adjust the height 349.0mm to the
screen holder upper surface as the setting
reference.

8. If not within the specification, turn “SERVO
MOTOR” on the main control panel [OFF].
9. Move the stage to any position where you can
adjust it easily.
10. Attach the dial gauge to the rail guide.
11. Zero the dial gauge.
12. Loosen the cotters.
13. Rotate the pulley and adjust the height.
14. Tighten the cotters.
15. Check the height of the height measuring jig and
the rail guide again.
16. Adjust the dog so that the origin sensor detects
correctly.
17. Turn “SERVO MOTOR” on the main control
panel [ON].
18. Return to origin of the ST axis and check the
origin sensor detects correctly again.
=CHECK=
Be sure to check the symmetry of the origin
sensor.
19. Check the height of the stage, the loader rail and
the unloader rail.
=CHECK=
Make sure that there is no interference for the
PCB transfer.
20. Check the height of the screen holder as the basis
for the stage height.
21. Check the (±) limit sensors.
