Beam delivery optical cable installation
WARNING
• Operation and maintenance of automated equipment involves potential hazards.
• Only authorized service personnel should perform this service.
• REMOvE ALL POWER tO tHE FIBER LASER SUPPLy ENCLOSURE BEFORE BEGINNING
PROCEDURE.
• Undesired results may occur if these instructions are not followed exactly in order, or if any
steps are not completed.
1. Carefully route the beam delivery optical cable from the fiber laser supply enclosure through the protective
cable trays of the machine frame to the laser head.
Note 1: Sometimes it is not possible to rotate the bayonet on the beam delivery optical cable to align the red
dots on the collimator and the bayonet, after it has been routed to the laser head, without creating
excessive torsional tension on the cable. In this case remove the 3 Allen head cap screws that attach
the laser head adaptor to the laser head mounting bracket. Then rotate the collimator so that the red
dots can be aligned without putting excessive twist to the delivery fiber and reinstall the 3 Allen head
cap screws. The laser head adaptor can be rotated in 120 degree increments to relieve excess torsion
on the beam delivery optical cable.
2. Inspect the entire path of the beam delivery optical cable and verify that the minimum bend radius specification
of 100 mm (4 in). is not violated and that there are no pinch points that could damage the Beam delivery optical
cable during machine motion.
3. Verify that there is enough length in the beam delivery optical cable at the Laser Head to allow for the motion of
the lifter axis while raising and lowering the laser cutting head
4. Temporarily secure the end of the beam delivery optical cable near the laser head until it is time to connect it to
the collimator.
Note Do not remove the black protective cap from the end of the
beam delivery optical cable until instructed to do so later in these
instructions
