Field Change Order #510F28442 - DLC Cassette Centering Type 2 (Anti-Collision Kit)

Description: The purpose of this FCO is to improve the reliability of the Cassette-Centering System by replacing the Centering Arms with a newly designed version.

1. Reason For Change
• To prevent plates from entering underneath the Centering Arms.
• To avoid collisions between the loading system suction cups and the Centering Arms on certain plate sizes.
• To improve the reliability of the Cassette-Centering System.
  
  
2. Description of Change
   Replace the existing cassette Centering Arms with the newly designed assembly.
   
   
3. Change Procedure
   1. From the application, release the cassette.
   2. Center a single plate with the Centering Arms.
      
      
   3. Tighten the screws to secure the position of the plate.
      
      

Note: The following steps describe the process of removing the old Centering Arms, and installing the new ones. Do not remove both at the same time. Remove and install one, then remove and install the other. The left and right Centering Arms are identical.

4. Remove one of the Centering Arms by removing the 2 Allen screws.
   
   
5. Install the new Centering Arm using the Allen screws that you removed in step 4. Check that it touches the plate as the old Centering Arm did.
6. To adjust the Centering Arm, open the 2 Allen screws on its adjustable edge.
   
   
7. Slide the adjustable edge down, making sure that it does not touch the cassette surface.
   
   
   
8. Repeat steps 4-7 to replace the second Centering Arm.
9. An extender is required to center GTO plates, and to avoid collisions between the loading system Suction Cups and the cassette Centering Arms on certain plate sizes, for example, 510 mm and 525 mm. The new extender has the same adjustable edge as the Centering Arm.
   Note: The old extenders fit the new Centering Arm.
   
   
   

Upper Tray

In the upper tray, perform the same procedure as for the main compartment, with the following exceptions:

• Since the upper tray does not have tightening screws, it is recommended to mark the Centering Arms location after centering the plate.
• The upper tray does not have an adjustable edge.
• The DCL Upper Arm and extender are shown below.
  
  

4. Test Procedure:
   
   
   1. Load plates into the cassette.
   2. Center the plates with the Centering System, and verify that the plates do not enter underneath the Centering Arms.
   3. Perform plate loading.
   4. Verify that the Centering System in the Lotem does not move the plate, to assure that the Cassette Centering system is synchronized with the Machine Centering System.
