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.

Handbot Assembly: Removal
1. Determine where the defective HandBot is located.
2. If this is a 4 bot library with no Service Safety door, the library should be varied offline to the host before opening the Access door.

3. If a service safety door is present and the HandBot is in the:
    a. Left service area, the left elevator will go offline automatically by engaging the SSD.
    b. Right service area, the right elevator and one or both caps will go offline when the SSD is engaged.
4. Open the appropriate library front door.
5. Open the rail brushes by moving the locking lever away from the outer wall.
6. Fully loosen both T15 captive screws.
7. Pull down on the upper pre-load assembly to free the rollers from behind the upper rail.
8. Tilt the HandBot assembly away from the upper rail.
9. Remove the HandBot from the library and place it safely away from the work area.

HandBot Assembly: Replacement
1. Carefully remove the replacement HandBot from its shipping container.
2. Verify the rail brushes are open.  If necessary, move the locking lever toward the Z-assembly.
3. Fully loosen both T15 captive screws on the upper pre-load assembly.
4. Pull straight down on the pre-load assembly so that it rests on the screw heads.
5. Position the HandBot next to the rail assembly with the tip of the HandBot tilted away from the upper rail.
6. Insert the lower pre-load assembly roller into the lower rail.
7. Move the top of the HandBot assembly toward the upper rail, resting the top rollers on the upper extrusion.
8. Push up on the upper pre-load assembly, placing pre-load assembly rollers behind the upper extrusion.
9. Carefully align the upper pre-load assembly with the upper frame so there is no gap between the two parts (tapered locating pins fit into their respective holes).
10. Tighten both T15 screws evenly.
11. Move the HandBot back and forth slightly to verify that it glides easily.  Any binding could damage the brushes.
12. If the HandBot does not move easily, re-check your work.
      Remove and re-install the HandBot, if necessary.
13. Remove the rail brush locking lever shipping tape, if present.
14. Move the rail brush locking lever toward the outer wall to engage the brushes.
15. Move the HandBot slightly back and forth to verify that it glides easily.
16. Close the library doors.
17. If the service safety door was activated, turn the maintenance key to its vertical position.
18. Observe Wait LEDs on the keypad after the front door is closed.  If Wait LEDs are flashing, code is being downloaded to the replaced HandBot.
19. If the entire library is offline, ask the operator to place it back online to ACSLS/HSC.
20. Once the Service Safety Door is centered and the bot completes the initialization the elevator and caps should automatically come back up onlin
