Water/water IPG chiller
ð Check the temperature and the pressure of the house water sys-
tem.
ð Check the fill level of the tap water tank in the laser chiller.
Water/air IPG chiller
ð Check the condition of the filter pads. If the filter pads are heavily
soiled, they must be replaced.
ð Check the ambient temperature.
Message
Feeding fiber interlock
Type
Alarm
Reset
Manual
Description
The alarm message Feeding fiber interlock indicates the status of the
safety circuit of the feeding fiber safety circuit.
Triggering of the Feeding fiber interlock alarm leads to an immediate
shutdown of the laser power supply and therefore the laser emission.
The operating status Laser ready is reset, and the status Laser error is
activated.
Possible
causes
• The feeding fiber is damaged.
• The fiber connector of the feeding fiber is not (correctly) inserted
into the integrated optics.
• The bayonet mount is not properly connected.
• The process optics are overheated.
Fault diagnos-
tics / trou-
bleshooting
ð Using the guide laser, check whether the feeding fiber is optically
in good condition. If necessary, have the feeding fiber replaced.
ð Check whether the feeding fiber is correctly inserted into the in-
tegrated optics.
ð Check whether the bayonet mount is correctly connected.
ð Check the temperature at the fiber receptacle of the optics. At a
temperature of 70°C, the temperature sensors in the fiber recep-
tacle interrupt the safety circuit.
ð If the temperature at the fiber receptacle is too high, you should
• check the welding parameters (back reflection may be too high).
• allow the fiber receptacle to cool.
After cooling the fiber receptacle, the error can be reset.
