Field Change Order #27343 - Centering Motor with 2 mm Pin

Description To improve the centering system reliability by changing the centering motor assembly.

1. Reason For Change

• To avoid cutting of the spring pin in the sprocket.
  
• To improve the centering system reliability.

2. Description of Change

Replace the pin in the centering motor sprocket assembly with a 2 (mm) dowel pin.

3. Change Procedure

• From the GUI, release the cassette and open the front door.
  
• Identify the pin in the sprocket wheel. If it's a dowel pin (picture no.1)- implementation of this FCO is not needed. If it's the spring pin (picture no. 2) - the FCO must be implemented.
  
• Close the application and shut down the machine.

Note: Mark the centering system location, to ease connection later.

• Remove the two screws from each side of the centering system (picture no. 3)

• Disconnect the wiring connector from the centering motor and remove the centering system from the machine.

  Note: Before releasing the motor assembly, move the short pins to the edge of the centering system. This will ease installation later. (Picture 4).

• Release the two screws that connect the motor assembly to the centering system. (Picture no. 4)

• Reassemble the new centering motor. Use loctite 242 to secure the screws.

Note: Make sure the chain is tensioned before tightening the screws.

• Reassemble the centering unit back into the machine.
  

4. Test Procedure

• Adjust the centering system according to the procedure in the Tic:
