Background

This procedure enables you to check the function of all laser interlocks, and to identify interlocks that are not functioning properly.

Requirements

Laser interlock testing jig (p/n 504S4E151).

Procedure

1. Close the PC controller application, and shut down the machine.
2. Remove the rear, lower poanel and trapezoid panel.
3. Locate the L-box power plug in the distribution box, and disconnect the L-box power connector.
4. Connect the laser interlock testing jig connector (shown below) to the L-box power plug on the distribution box.

   Note: Be careful not to step on the jig.



6. Power up the machine. The jig indicates laser interlock function, as follows:
   • If one or more doors are not closed, the light in the jig is off.
   • If all doors are properly closed, the light in the jig is on.
   • If all doors are closed but one or more laser interlock is malfunctioning, the light in the jig is off.
7. To verify the function of individual laser interlocks, open and close each door from the PC controller application, and verify that, in the GUI, the machine status changes appropriately, as described below:
   • Ready: When all doors are closed and the laser interlocks are functioning properly.
   • Off-line: When something is wrong, including one or more of the doors being open.
