FIELD ENGINEER INSTRUCTIONS

PROBLEM OVERVIEW: Robot is not functional

CONFIRM THE FAULT BY CHECKING: Check status of robotic hand using SL Console.

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY? : If robot is behind service safety door, Customer should vary CAP and elevators offline using SL Console. If the robot is not behind the service safety door, Customer must halt hand-bot operation by placing the library offline with either ACSLS or HSC.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

- Perform health check on library via SL Console.
- Verify firmware is at current levels.
- Review error logs to understand actual robotic failure.
- Attempt to place hand back online via SL Console.
- Run SL Console Self Test diagnostic to check functionality.
- Re-initialize robotic hand.
- If not fixed, replace FRU.

Refer to the SL8500 Service Manual for the complete instructions, including pictures, cautions and notes for the removal and replacement of the robot.

Robot Assembly (Bulk CAP Library Only): Removal
Caution –
Initialization Error:
For all 8-robot and bulk CAP libraries, robot replacement should not be done without using the Service Safety Door.
If a defective robot does not position itself in the service area after a failure:
1. Check the library event log and determine if the robot encountered a “reach unsafe” error. Firmware will not move the robot in this case.
2. If the error is not associated with a “reach unsafe” fault, attempt a soft boot through the StorageTek Library Console diagnostic menu.
3. If there is a “reach unsafe” error or if the soft reboot does not move the robot into the service area, it is necessary to vary the libraries offline, open an bulk CAP door, and physically move the robot into the service area.
4. Close the access door and replace the robot using the Service Safety Door.
    1) Determine where the defective robot is located.
Note –
If the library is unable to move the robot into a service area, the operator must halt robot operations. Start with Step 2.
If the robot is inside a service area, start with Step 3.
    2) Ask the operator to place the library offline to ACSLS/HSC.

    3) Ask the operator to take the CAP door and elevator offline to StorageTek Library Console.
Caution –
Be sure that the elevator array will not interfere with your work area. Also, left robot removal is within a more confined space than a right robot.
    4) Open the appropriate CAP door (see “Opening Access Doors” on page 39 ).
Warning –
There is 48 VDC present on the electrical bar of powered rail assemblies (in the case of a service safety door activation). DO NOT TOUCH the electrical bar during the remaining steps.
    5) Open the rail brushes by moving the locking lever (1) shown in FIGURE 1-94 away from the outer wall.
Note –
You may need a Kik Step or small ladder to reach robots on the upper rail.

    6) Pivot the hand:
        a. for left side robots, toward the outside wall of the library.
        b. for right side robots, toward the inside of the library.
    7) Remove any cartridges that may be in the CAP array closest to the front door and give them to the operator.
    8) Lift up on the bottom of the array (1) shown in FIGURE 1-95 and pivot the bottom out (2) to remove the array.

    9) Place the array out of your work area.

   10) Fully loosen both T15 captive screws (1) shown in FIGURE 1-96 on the preload assembly (2).

   11) Pull down on the upper preload assembly (1) shown in FIGURE 1-97 on page 107 to free the rollers from behind the upper rail.
Caution –
Do not insert a metal tool to aid in lowering the preload assembly in the following step.

Caution –
Possible Equipment Damage: Do not grasp or bump the lower plate or any plastic parts on the robot during removal. Lift the robot Z-column and frame only.
    12) Tilt the robot assembly away from the upper rail.
    13) Remove the robot from the library and place it safely away from your work area.

Robot Assembly (Bulk CAP Library Only): Replacement
Robot replacement within bulk CAP libraries requires the use of the tool (1) shown in FIGURE 1-98 that is supplied with the conversion bill. From the conversion bill instructions, one tool should have been stored within each door.
Warning –
There is 48 VDC present on the electrical bar of powered rail assemblies (in the case of a service safety door activation). DO NOT TOUCH the electrical bar with the robot replacement tool during the remaining steps.

1. Place the new robot of a secure, flat surface.

2. Obtain the replacement tool.
Note –
The lower portion of the L-shape tool will always face down and toward the front of the library.
3. Firmly compress the rear spring on the replacement robot and insert the tool as shown in FIGURE 1-99.
4. Firmly compress the front spring on the replacement robot and insert the tool as shown in FIGURE 1-99.

5. Check that the straight portion of the L-shape of the tool (1) illustrated in FIGURE 1-100. is facing the front door, within the pre-load assembly behind the raised tabs (2), as shown in FIGURE 1-100.

6. You must check and re-check that the tool is correctly inserted:
   a. FIGURE 1-101 on page 109 shows the tool incorrectly inserted for a right side robot.
   b. FIGURE 1-102 shows the tool incorrectly inserted for a left side robot.

7. Pivot the bottom of the robot into the lower extrusion.
8. Pivot the top of the robot inward toward the wall.
9. Check that the upper pre-load rollers (1) shown in FIGURE 1-103 on page 110 are behind the extrusion (2).

10. Tighten the two T15 screws.
11. Disengage the tool by pulling down on the lower portion of the tool.
12. Place the tool inside the outer door.
13. Again, visually check that the preload rollers are correctly positioned.
14. Replace the CAP array.
15. If the customer desires, replace any cartridges that may have been inserted into the array.
16. Engage the brushes by pushing the locking lever (1) shown in FIGURE 1-104 on page 111 toward the wall.

17. Return the service safety door to its central position.
18. Close the front door.
19. Proceed to “Robot Verification” on page 278.

- Record specific error code and messages associated with failure in case notes.
- Record all relevant visual observations of error in case notes.
- Record final fix in case notes.

CONFIRM THE FIX BY: Check status of robotic hand using SL Console

OBTAIN CUSTOMER ACCEPTANCE

WHAT ACTION DOES THE CUSTOMER NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE: Customer should vary the CAP and elevator online and/or place the library back online with ACSLS or HSC, as required.
