AC Fuses and AC Relay PCB
The AC fuses and the AC relay PCB are located under the AC distribution plate. The fuse block
is next to the AC relay board. The fuse closest to the outside is Fuse 1 (F1). See
System Wiring
Diagram for a description, part number and designation of each fuse and relay. The fuse
numbers follow sequentially to the center of the laser: F1 through F9.
Replacing the High Voltage Power Supply
1. Disconnect the laser from the AC service.
2. Disconnect the HV Blocking Diode and GND.
3. Disconnect the control cable from the power supply.
4. Remove the two flat head screws attaching the HVPS to the center post of the main
chassis.
5. Completely loosen and move the center post of the frame to the side. It may be necessary
to remove the line filter and bracket on systems equipped with these items.
6. Loosen and remove the flat head screw that attaches the shelf of the main capacitor to the
chassis. This will allow the shelf to swing to the side slightly allowing the supply to pass
by the cables.
7. While supporting the HVPS chassis, remove the remaining two 8-32 Phillips flat head
screws, that hold the supply to the main chassis, and then remove the supply.
8. Remove the AC connection.
9. Reverse the above steps when installing a supply.
Calibrating the High Voltage Power Supply
Follow the procedure for testing the high voltage power supply as detailed in the Final Test and
Calibration Procedure.
Low Voltage Power Supply
There is one low voltage power supply (LVPS) on this system mounted to the upper partition
under the laser control PCB. This supply has two +12 V outputs, -12V and 5 V that is used for
the logic control and power for the different solenoids.
Adjustment information and procedure on the LVPS can be found in the Final Test and
Calibration Procedure.
Pin designations can be found on the System Wiring Diagram , #105-1847-000.
