Elevation Characterization Procedures

Prerequisites

Overview

1 Elevation Characterization

Procedure

  1. Move the cradle and IMS table to the OUT-limit position.
  2. Remove the front base cover, right base cover, and top right cover.
  3. Set the service switch (MODE_SEL) to the SERVICE to enter the service mode.
  4. Confirm that the “ELEV” LED on the GTCB board in the table is ON. If it is NOT ON, press the “Motion Target” button until “ELEV” LED is ON.

    Figure 1. LED's on GTCB board

  5. Press and hold the service switch (ACTION) to the IN/UP position to move the table to the mechanical UP-limit position.
  6. Confirm that the “POT_ADJ UP” LED (Green) is ON. If it is NOT ON, perform Height Potentiometer Adjustment. Refer to Height Potentiometer Adjustment.

  7. Press the two “Characterize” Buttons at the same time to start characterization.

    Figure 3. Starting Characterization

  8. Confirm that the “UP/IN” LED is ON. See Figure 1.
  9. Using the Service Switches, move the table at 980 +/- 0.5mm of the distance between characterization points (the bottom of the table base, not floor, to the front cutout of the IMS frame as shown).

    Figure 4. Characterization Points

  10. Press the two “Characterize” Buttons at the same time. See Figure 3.
  11. Confirm that the “DOWN/OUT” LED is ON. See Figure 1.
  12. Using the Service Switch (ACTION), move the table at 700 +/- 0.5mm of the distance between characterization points (the bottom of the table base, not floor, to the front cutout of the IMS frame as shown). See Figure 4.
  13. Press the two “Characterize” Buttons at the same time to start characterization. See Figure 3
  14. Confirm that both of “UP/IN” LED and “DOWN/OUT” LED are ON. See Figure 1.
  15. Using the Service Switch, move the table to the mechanical down-limit position.
  16. Press the two “Characterize” Buttons at the same time. See Figure 3.
  17. 5 - 10 seconds later (to write characterization data to the flash memory), confirm that both of LED's (UP/IN and DOWN/OUT) are OFF. See Figure 1.
  18. If both of LED's blink during procedures, it means that characterization fails. Retry characterization.

2 Height Potentiometer Adjustment

When the Height Potentiometer (elevation potentiometer) is replaced or it must be adjusted again, perform this procedure.

Procedure

  1. Using the Service Switches, move the table to the mechanical UP-limit position.
  2. Confirm that the “POT_ADJ UP” LED (Green) is ON. If it is NOT ON, adjust the height potentiometer.
    1. Remove the left base cover, left IMS side cover, front left side cover, rear left side cover, and front left leg plate.
    2. Loosen the two POT bracket bolts to release belt tension.
    3. Rotate the gear of the height POT until “POT_ADJ UP” LED is ON.
    4. While applying proper tension to the POT belt, secure the two POT bracket bolts.
    5. Confirm that the “POT_ADJ UP” LED is ON.

      Figure 5. Height POT Adjustment

  3. Using the Service Switches, move the table to the mechanical DOWN-limit position.
  4. Confirm that the “POT_ADJ DOWN” LED (Yellow) is ON. If it is NOT ON, adjust the height potentiometer again.
  5. When finished with characterization set the service switch (MODE_SEL) to the NORMAL position for customer use.

3 Finalization

Procedure

  1. Install the covers in the reverse order of removal.
