Pipettor X-Axis Encoder Cap Installation

Corrosion inside Pipettor X-axis motors can occur causing intermittent movement failures on the Panther and Fusion pipettor gantries.
A Encoder cap should be installed on all motors to protect the encoders from corrosion.

Parts and Materials Required

• Pipettor X-Axis Motor Encoder Cap (Bag of 12)

Procedure

1. Safely shut down the PC and Power off the System.
2. Remove the rear Panther (and Fusion, if servicing a Fusion) canopy to access the X-motors.
   
3. Remove the 4 hardware screws that hold the side Plexiglas.
   Carefully remove the Plexiglas and set aside.
4. Carefully inspect the encoder cable’s wire sockets.
   Confirm they are firmly attached to the connector.

   Note— If the Encoder Cable is damaged, replace the Encoder Cable. The same Encoder Cable is used for ALL Pipettor motors

   

5. (Optional Step) Remove the X-Axis Motor cable harness.
   The harness would need to be removed ONLY if it is difficult to install the Encoder Cap.

   

6. Install the Encoder Cap, by pressing on the cap so that the cap covers the encoder cable and motor power cables.
   During installation be careful not to put excessive strain on the cables.

   

7. Ensure that the cap is fully seated onto the X-Axis Motor and fully covering encoder.
   Below are examples of incorrect & correct installation of the encoder cap.

   

8. If the X-Axis Motor cable harness was removed, re-install now.

   

9. Final Procedures
   1. If the instrument was moved and/or unfused:
      1. Move instrument back to its correct location
      2. Reconnect the Fusion to the Panther. (FUSION ONLY)
      3. Teach Pipettors (make sure the Elution track is taught - FUSION ONLY)
      4. Teach LDLinear distributor handoff (perform Fusion System OQ - FUSION ONLY))
      5. If canopies were removed, re-install canopies
   2. If the instrument was NOT moved and/or unfused:
      1. If canopies were removed, re-install canopies
