10006 Internal Fault IDSP NEUT IGBT Inverter Neutral IGBT Fault System Severity Level 2 Hardware circuit protection is provided in the Neutral power module to detect overcurrent, undervoltage, and over temperature conditions. Software declares a Neutral IGBT fault when any of these circuits is not operating properly. An automatic recovery is attempted after a Neutral module shutdown. Symptom Probable Cause Analysis Repair Solution Inverter Neutral IPM Module fault is detected. Neutral IPM Overcurrent The 3-phase load is unbalanced, or too much DC current is flowing to the load. Adjust the load. Inverter Neutral IGBT is damaged LCM Neutral IGBT needs replacing Replace the LCM Neutral IGBT 10007 Internal Fault IDSP DC OV Inverter DC Bus Overvoltage System Severity Level 4 Several components connected to the DC Bus have maximum operating voltage limits. To protect these components from failure, software detects a fault condition and shuts down the system when the DC Bus voltage input exceeds the DC Bus Voltage Limit. Symptom Probable Cause Analysis Repair solution DC Bus Voltage reading is higher than its fault limit Open/loose connection Check the ECM to LCM cable. Tighten cable connections DC Bus Voltage reached fault limit. One main reason to have this fault is the generator brake over- temperature. Excess number of offload operations in a short period of time can cause the brake over- temperature fault. Increase the time between each off-load operation. The DC Bus Over- voltage fault limit is wrongly set. Make sure that the LCM PM is programmed properly, and it is supported by the control software being used. Re-program the LCM Control Board PM. Faulty LCM Control Board Circuitry on LCM Control Board has failed. Attempt a LCM Control Board PM upload. Replace LCM Control Board. Faulty LCM Power Board Circuitry on LCM Power Board has failed. Attempt a LCM Control Board PM upload. Replace LCM Power Board Observe Safety Precautions - Refer to Safety Instructions for Details 430013-001 Rev C (July 2003) 11-7 Model C60 Troubleshooting Guide This information is proprietary to Capstone Turbine Corporation.
