Machines affected

Platesetters containing Local3 boards

Component

Local3 boards

Problem

Two conflicting components within the platesetter cause Local3 board error messages to appear:

• Local3 board on the left hand side: Interlock is open error message appears at startup—even though the platesetter's doors are closed.
• Local3 board on the right hand side: Error On Load Roller Valve Valve/Solenoid HP detector : No change/No Valid state of Detector in OFF Operation.
• MCU intermittently stops at the wrong level.

These components may also cause valve and/or gripper error messages to appear.

Solution

Connect a closed circuit connector to each of the Local3 boards.

Important: This FCO contains three connectors per each Local3 board. Store any unused connectors in your tool box.

Time needed to implement

15 min.

Parts needed

Procedure

1. Shut down the platesetter via Lotem Controller.
2. Shut down Lotem Controller and turn off the PC.
3. Individually remove each of the two Local3 boards from the platesetter.
4. Remove the four screws on each of the Local3 board covers:

   
   

5. Remove the Local3 board covers:

   
   

6. Make sure that the jumper, included in each kit
   (p/n 190-00002), is undamaged and that the jumper shunt is wired correctly:

   
   

7. Holding the jumper by its sides, carefully connect it to the J5 socket located on the Local3 board:

   
   

8. Affix one Local3 FCO #512-02139A label (p/n 382-00277A), included in each kit, onto the Local3 board.
9. After adding a jumper to each Local3 board, replace the board covers and secure them with the four screws you removed in step 3.
10. Replace the Local3 boards inside the platesetter.

When done

Restart the platesetter. Check that the error message Interlock is open has not reappeard and make sure that the platesetter is working correctly.
