Solution

DISPATCH INSTRUCTIONS
- WHAT SKILLS DOES THE ENGINEER NEED:
Knowledge of the StorageTek 9310 and L5510 library.

- TIME ESTIMATE: 90 minutes

- TASK COMPLEXITY: 2

FIELD ENGINEER INSTRUCTIONS:
- PROBLEM OVERVIEW
Library is not functional and taking Z type FSC errors.
Robotics not moving up and down.

- WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE
RESOLUTION ACTIVITY?
LSM must be offline to all systems as the access door will be opened.

- WHAT ACTION DOES THE ENGINEER NEED TO TAKE:
Refer to the 44xx/93xx/L55xx Maintenance Manual for complete instructions on how to R&R the Z-motor assembly. It will provide all Pictures, Notes and Cautions related to the following instructions.

Z Motor Assembly Removal (9310/L5510 Only)
1. Enter the LSM using the proper procedures.
2. Remove the 2 screws attaching the Z motor flex to the Z motor encoder. Retain the screws for
reattaching the flex to the new motor.
3. Disconnect the Z motor flex from the encoder.
4. Remove the Z motor power cable connector J720 by squeezing the ears of the connector inward and
withdrawing the connector from the Z column cap assembly.
5. Cut and remove the tie wrap securing the Z motor cable to the Z column cap assembly.
6. Remove the lower 2 screws attaching the Z motor to the Z column cap.
7. Pull the counterweight belt up, and remove it from the Z motor pulley.
8. Remove the Z motor assembly from the Z column cap assembly by removing top 2 screws while
supporting the motor. Retain the screws for attaching the new motor.

Z Motor Assembly Replacement (9310/L5510 Only)
1. Attach the Z motor assembly to the Z column cap assembly using the 4 screws previously removed.
2. Tighten the screws to a torque of 3 NM (26 in.-lb.).
3. Lift the counterweight belt up, and place the belt over the motor pulley.
4. Attach the Z motor power cable connector J720 to the Z column cap assembly by pushing the end of the
connector into the connector cutout until the ears of the connector lock into place.
5. Secure the Z motor cable to the hole in the Z column cap assembly with a cable wrap.
6. Connect the Z motor flex to the Z motor encoder.
7. Secure the Z motor flex to the encoder using the 2 screws previously removed.
8. Tighten the screws to a torque of 0.95 Nm (8 in.-lb.).
9. Restore library to functional state.
10. Run diagnostics to the LSM to verify that the library is operational.

OBTAIN CUSTOMER ACCEPTANCE
- WHAT ACTION DOES THE CUSTOMER NEED TO TAKE TO RETURN THE SYSTEM TO
AN OPERATIONAL STATE:
Bring the library online to all systems and verify the function of the LSM.
