6-2 Calibration procedure
6-2-1 Upper Optical Fork Positioning
• If the height of the ceiling has changed, then follow the steps in this section, otherwise go to 6-2-2,
Lower Limit Adjustment (Lift Potentiometer Lower Reference Voltage at 0 mm).
• 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 2400mm (94.6 inches)
and 2500mm (98.4 inches)
- Remove the front covers (refer to Job Card PHY
A044 - Remove/Reinstall Gantry Covers on page
523).
- Place the optical fork in the middle position (allows
750 mm lift travel).
3. If the ceiling height is between 2300mm (90.6 inches)
and 2400mm (94.6 inches)
- Remove the front covers (refer to Job Card PHY
A044 - Remove/Reinstall Gantry Covers on page
523).
- 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.
