4687 - Accessor Y motion failed because of a loss of 40V DC power

Edit online

The Y motion of the robotic accessor failed due to a loss of power to the robotic accessor. This could be caused by a cable to the robot being improperly plugged or faulty RCC card on the robotic accessor. This fix procedure describes how to diagnose and correct this issue.

Fix procedure

  1. Put the library in service:
    1. From the management GUI., go to Actions > Change Library State.
    2. Choose In Service Mode (Offline) option and then click the Set button.
  2. Open the front door.
  3. If a cartridge is stuck between the gripper and a library slot, follow the “Cartridge recovery from stuck state between slot and gripper” procedure.
  4. If a cartridge is inside the gripper, follow the “Cartridge removal from gripper” procedure.
    Additional Troubleshooting:
    1. Verify that the Y-flex track cable is securely connected to the robotic accessor and the Front Side Card (FSC).
    2. Inspect there are no obstacles in the way of the robotic accessor, such as a cartridge sticking out of a cell. Other possible causes include debris in the Y-rail gear rack such as a piece of plastic, or other debris which would interfere with accessor motion.
    3. Close the door and set the library online:
      1. From the management GUI., go to Actions > Change Library State.
      2. Choose Online option and then click the Set button.
    4. If the problem has been resolved, you are finished, otherwise continue with the next step.
    5. Put the library back in service mode (See Step 1)
  5. Replace the robotic accessor:
    1. Replace the robotic accessor using the Robotic Accessor videos.
    2. Reset the LCC. From the management GUI, go to Library > Nodes Cards. Right click on the LCC node card and choose Reset This process will log you out of the GUI..
    3. Close the front door and calibrate the library. From the management GUI, go to Actions > Calibrate Library and click Yes.
    4. Put the library online. From the management GUI., go to Actions > Change Library State and choose Online option.
    5. Run Library Verify. From the management GUI, go to Actions > Library Verify keep the default options and click Next
Attention: If the problem has occurred multiple times and still not resolved, contact IBM support.
