4.5 FC-LD (Oscillation Unit) Inspection and Replacement
9
To remove the optical fiber, loosen the
four screws for the optical fiber fixture at
the back of the Control Unit.
10
Turn the fixing nut of the optical fiber
counter-clockwise. Keep it level and
pull it out slowly.
11
After unplugging the optical fiber, cover the end with the cap. For the FC-LD side connector as
well, cover the connector with a cap for the head side.
12
Unscrew the four hex screws holding
the FC-LD.
There is a graphite sheet between
the heat sink and FC-LD. This sheet
will be used again, so handle it
carefully and save it.
13
With the graphite sheet between the heat sink and replacement FC-LD, secure the FC-LD with
four hex screws.
14
Remove the caps from the FC-LD and optical fiber.
To prevent damaging the optical fiber, maintain a bending radius of at least 150 mm.
Handle the end surface of the fiber carefully to prevent damaging or soiling it.
If the graphite sheet is bent or damaged, thermal conductivity will worsen
considerably. Contact us if you need to know the model number of the graphite sheet.
Loosen the four screws.
