How should sudden laser faults be handled during a live concert?
Direct answerPrepare backup units and key consumable parts, fit an emergency stop and safety interlock that cuts output instantly, and use remote diagnosis to troubleshoot before and during the show.
Fault Response Plan
- Carry a backup fixture for every critical laser position on the rig
- Stock the parts that fail most in touring: power supplies, galvo scanners and control boards
- Fit emergency stop and interlock so a faulty unit can be isolated without killing the whole rig
- Keep remote diagnosis enabled so a technician can identify the fault before the unit is opened
- Assign one person to decide between repair on the spot and swapping the fixture
What Makes a Unit Field-Serviceable
- Modular internal layout so a module can be exchanged at the venue
- Clear fault codes readable on the display or over the network
- Standard connectors and fixings that match the rest of the rig
- Documented spare-part list agreed at purchase
A touring rig is only as reliable as its spare-parts kit, so build the kit around the parts that actually fail under road conditions.
