Interlock Circuit Diagram

The +24 VDC Interlock Circuit 

The +24 VDC Interlock Circuit runs from the +24 VDC LVPS to the L/H Door 
Interlock Switch, the R/H Door Interlock Switch, and the Front Door Interlock 
Switch back to the Engine Control Interface Board, then into the Engine 
Control Board. Opening this circuit prevents the Laser Unit and the 
High-voltage Power Supplies from operating.

1.

With all doors closed and printer power On, check for +24 VDC between 
P535-2 of the Engine Control Interface Board and frame ground. 

2.

If +24 VDC is not present, see Troubleshooting the +24 VDC LVPS on 
page 3-90 to verify the +24 VDC LVPS is working.

3.

If working, then check the LH Cover Interlock Switch, the RH Cover 
Interlock Switch and the Front Cover Interlock Switch.
