Troubleshooting should take into consideration: • System Error
• History, including events just before an arc.
• Error code.
• Situation, circumstances when an arc occurred.
• Time and Date.
• Environment, temperature, vibrations, power supply,
electrical/magnetic disturbances.
• How an arc is indicated and nature of its occurrence.
