Lotem^® 800 family platesettter with Omron^® interlocks

Background

This procedure describes how to check and adjust the unload panel on Lotem 800 family platesetters with Omron interlocks.

Requirements

• Unload panel jig (part number 690-00723A)
• Digital voltmeter (part number xxx)
• Interlock jig cable (part number 220-01407A)
• Masking tape
• Hex keys

Procedure

Checking and adjusting the unload panel

1. Make sure the platesetter’s distribution panel is installed.
2. Raise the top rear cover.
3. Remove the black upper screw from the left side of the unload panel:
   
   
   
   
4. Release, but do not remove, the lower screw from the left side of the unload panel:
   
   
   
   
5. Open the left side door and the laser barrier.
6. Remove the unload panel jig (part number 690-00723A) from the Lotem 800 doors and interlocks adjustment jigs kit (part number 518-01578A). The jig comprises of two protruding edges.
   • The thin and thick protruding edges of the jig are used for determining the correct position of the Omron interlocks:

7. Disconnect the Molex^® connector belonging to the Omron interlock (located on the left side of the unload panel):
   
   
   
   
8. Plug the probes into the appropriate jacks on the digital voltmeter:
   
   
   Important: Plug the black probe into the digital voltmeter’s negative (common) jack, and plug the red probe into the digital voltmeter’s Volt/ohm/temp jack (not the A or mA jack).
9. Remove the interlock jig cable (part number 220-01407A) from the kit. On one end of the interlock jig cable are two crocodile clips, on the other end there is a Molex connector.
   • Connect one crocodile clip to each probe:
     
     
     
     
   • Connect the Molex connector to the interlock’s connector:
     
     
     
     
10. Set the dial on the digital voltmeter to the diode indicator:
    
    
    
    
11. From the left side door, insert the unload panel jig’s thin edge between the unload panel and the chassis. For best results, insert the jig just above the interlock:
    
    
    
    
12. Push the unload panel against the thin edge of the jig:
    
    
    
    
13. The digital voltmeter makes a beeping sound.
    
14. Insert the jig’s thick edge between the unload panel and the chassis.
15. Push the unload panel against the thick edge of the jig.
16. The digital voltmeter should not beep.
    If the digital voltmeter does beep, then adjust the Omron interlock operation key.
17. Check, and if required, adjust the platesetter’s rear cover, front cover, and side door.

Adjusting the Omron interlock operation key

1. Remove the unload panel.
2. Use a pencil to mark the outline of the interlock operation key:
   
   
   
   
3. Use a hex key to remove the two screws securing the interlock operation key.
4. Add the required number of spacers (part number 252-10209A) to the interlock operation key assembly:
   
   
   
   
5. Reinstall the interlock operation key, by using the marked outline as a guide.
6. Place two strips of masking tape over each end of the interlock’s entry point:
   
   
   
   
7. Close the top rear cover just enough for the interlock operation key to punch holes in the masking tape.
8. Manually open the top rear cover:
   • If no punched holes appear on the masking tape, then the interlock operation key is correctly positioned.
   • If punched holes appear on the masking tape, then reposition the interlock operation key and repeat steps 6-8.
