Service and Troubleshooting

7.3

Laser Module Faults

Error

Cause

Measures

No aiming beam and no
or low weld laser

Broken fiber optic cable
Damaged laser module

Replace fiber optic cable

No weld laser but
aiming beam ok

Interlock circuit not closed
Interlock circuit not powered
No gate or trigger signal

Wrong current setting
Fault on current supply

Check interlock wiring

Check interlock wiring

Check for active gate or trigger
signal
Check current setting
Replace laser module

Weak laser power

Dirty optics

Fiber optic not tightly connected to
Laser module or optical housing.

Damaged laser module

Check optics and clean if
necessary.
Check fiber optic connector on
laser module and optical housing.
Replace laser module

7.4

Optics fault

Error

Cause

Measures

Bad aiming beam or
bad welding result

Dirt on Optics
Broken fiber cable

Clean Optics
Replace fiber cable

No aiming beam
but welding ok

Aiming beam inactive or defect

Check the configuration of
Register 900.
Check Input X14 “Aiming Laser Off”

No aiming beam
and no welding

Broken fiber cable

Replace fiber cable
