CHAPTER 4: MAINTENANCE
LMV700 Nd:YVO

LASER MARKER
4-12 990-545
CAUTION
Ɣ
To prevent damage to the optical cable, never bend it beyond its minimum bend radius
of 5.9” (150 mm).
Ɣ
Carefully handle the end surfaces of the optical fiber to prevent scratching or soiling.
10. Remove the four, 3mm hex screws that
fasten the LD Module to the Control
Unit. Remove the LD Module.
11. Leave the graphite sheet (placed
between the heat sink and the LD
module) inside the Control Unit. If the
graphite sheet is cracked or creased,
replace it. The graphite sheet is used to
transfer heat from the LD module to the
Peltier Cooling device.
12. Install the new LD Module into the
Control Unit onto the graphite sheet.
Fasten the LD module with the four hex
screws removed previously.
13. Remove the dust cap from the new LD
module and place it on the old LD
module.
14. Remove the dust cap from the optical fiber and slowly insert it horizontally into the new LD
module. Keep the dust cap for the optical fiber in a safe place.
15. Secure the optical fiber onto the LD Module by turning the fastening nut CW (clockwise).
Tighten snugly, but do not overtighten .
16. Insert the LD – I/O connector so that
the red marks align.
17. Connect the LD protection relay, Peltier
power supply and LD Power Supply
connectors.
18. Move the short circuit jumper to the
RED
and
RED
terminals on the LD
module before powering up the Laser
Marker. Failure to remove the short
circuit between the Red and Black
terminals may damage the LD Module.
