Calibration Procedure
6-2-1
Upper Optical Fork Positioning
•
Use a measuring tape to measure the height of the ceiling:
1. If the ceiling height is equal to or greater than 2500 mm
(98.4 inches) (measured from the floor),
-
Leave the optical fork in the default position (the
upper position, allowing 850 mm lift travel),
2. If the ceiling height is between 2400 mm (94.6 inches)
and 2500 mm (98.4 inches)
-
Remove the front covers (refer to
A044 - Remove/Reinstall Gantry Covers
-
Place the optical fork in the middle position (allows
750 mm lift travel).
3. If the ceiling height is between 2300 mm (90.6 inches)
and 2400 mm (94.6 inches)
-
Remove the front covers (refer to
A044 - Remove/Reinstall Gantry Covers
-
Place the optical fork in the lower position (allows
650 mm lift travel).
Note:
The ceiling height ranges quoted above assume that there is a 70 mm marginal space between
the top of the Tube Head and the ceiling.
