Study Notes
Troubleshooting Lighting Issues
- Essential resources for troubleshooting include user manuals and experienced crew members.
- Common causes of lighting malfunctions often relate to improperly plugged cables, including DMX control and power cables.
- Checking instrument bulbs is crucial if only a couple of instruments fail to work.
- Swapping DMX and power cables can help identify faulty connections.
- Ensure proper patching by comparing instrument schedules to dimmer circuits for any mismatches.
- Verify instrument mode settings against manufacturer manuals; incorrect modes may lead to functionality issues.
Data Entry and Computer Systems
- Data entry at the computer-assisted lighting control desk includes patching, cue groups, preset modes, and IP addresses.
- High-end consoles integrate the computer, reducing IP address issues unless external devices are involved.
- Changing dedicated PCs may create IP address communication problems between the console and the PC.
- Patching and cue reports can be compared to instrument schedules and cue sheets to identify errors.
- Digital consoles can display error messages for invalid entries, assisting operators in troubleshooting.
Addressing Major Problems
- Simple troubleshooting techniques can often resolve lighting issues; referring to manuals may provide further guidance.
- Consult with stage management and electricians during performances to formulate contingency plans for serious failures.
- Health and safety of the cast, crew, and audience must be prioritized during emergencies, such as electrical faults or mounting failures.
- Documentation of health and safety procedures should outline responses to serious hazards and designate responsible personnel.
Reacting to Significant Malfunctions
- In the event of unresolved major malfunctions, the lighting operator must collaborate with stage management, including the head electrician, stage manager, and lighting designer.
- Backup solutions may include uploading software, reconfiguring systems, or swapping dimmers/instruments.
- Extensive re-cabling might be necessary for system restoration.
- Backup options may incur expenses, such as equipment purchases or rentals; budget approval is necessary before incurring costs.
