Replace the stabilized power supply as follows:
(1)Turn off the power to the CNC, then turn off the power to the laser
oscillator. In addition, open the main circuit breaker for the laser
oscillator.
(2)Disconnect all cables from the stabilized power supply.
(3)Remove the four screws or edge supports, then remove the stabilized
power supply.
(4)Mount a new stabilized power supply by reversing steps (2) and (3).
Connect the cables, noting the alignment marks. Ensure that no
terminals are loose.
(1)Turn off the power to the CNC, then turn off the power to the laser
oscillator. In addition, open the main circuit breaker for the laser
oscillator.
(2)Disconnect all cables from the control PCB.
(3)Remove the four screws, then remove the input unit control PCB.
(4)Mount a new PCB by reversing steps (2) and (3). Connect the cables,
noting the alignment marks. Ensure that no terminals are loose.
Replace the FS0–L interface PCB on the oscillator side as follows:
(1)Turn off the power to the CNC, then turn off the power to the laser
oscillator. In addition, open the main circuit breaker for the laser
oscillator.
(2)Disconnect all cables from the interface PCB.
(3)Remove the four screws or edge supports, then remove the interface
PCB.
(4)Mount a new PCB by reversing steps (2) and (3). Connect the cables,
noting the alignment marks. Ensure that no terminals are loose.
