Lower position successfully calibrated. Move to upper position. When reached press FOV button.
You must now proceed to Upper Limit Adjustment (Lift Potentiometer Upper Reference Voltage at
650 mm) on page 1691 to set the upper Lift Potentiometer Upper Reference Voltage.
6-2-3 Upper Limit Adjustment (Lift Potentiometer Upper Reference Voltage at 650 mm)
Use the following steps to calibrate the upper limit of the Lift Potentiometer:
1. When the Gantry LCD instructs you to move the lift to the upper position, use the control buttons on
the Tube Head to move the lift up to its highest possible position until it automatically stops.
The movement stops automatically when the lift reaches 650 mm above the lower limit (determined
by the Lift Encoder which accurately translates lift screw turns to height travelled).
2. Once the lift reaches its highest position and automatically stops, press the FOV size button (behind
the Tube Head) to signal completion of the upper limit adjustment.
The voltage of the Lift Potentiometer is sent to the firmware of the Lift Board and stored as the Lift
Potentiometer Upper Reference Voltage.
The Gantry LCD updates with the message "Lift node fully calibrated. Calibration can be saved or
canceled on ADS." and the AWS screen updates instructing you to either save or cancel the calibra-
tion (see Selection of the Lift Travel Limit (completion) on page 1691).
!
Notice:
If you do not move the lift up to its highest possible position until it automatically stops, and you
press the FOV size button the Gantry LCD updates with the message "Upper lift position out of
range. Check lift position or positioner signal! Then press FOV button.". In this case simply contin-
ue to move the lift up to its highest possible position until it automatically stops and then press the
FOV size button.
6-2-4 Selection of the Lift Travel Limit (completion)
Use the following steps to save the calibration results and set the lift travel limit,:
1. On the Lift Position and Upper Limit Calibration page, click the Save button.
A Lift Optical Fork Position Calibration page on the appears prompting you to select the upper optical
fork position.
2. Click on the button corresponding to the upper optical fork position that you set in Upper Optical Fork
Positioning on page 1689. Click the NO CHANGE button if the ceiling height has not changed, other-
wise click the corresponding button, as follows:
- 850 mm if the upper optical fork is in the upper position
- 750 mm if the upper optical fork is in the middle position
- 650 mm if the upper optical fork is in the lower position
3. From the Lift Calibration SAVED page that appears, click the OK button.
You are returned to the Calibration : Positioner Summary page.
4. From the Calibration : Positioner Summary page, click the Exit button to leave the Service Desktop.
6-2-5 Check the Lift Lower and Upper Travel Limits
Move the Arm to the lower position, then to the upper position and check if the Arm stops at the right
positions.
