6011 Internal Fault FLAMEOUT START Engine Flameout During Start-up System Severity Level 3 The software detects if the engine is not sustaining combustion after it has begun accelerating. This fault is declared if the engine TET drops by more than a predetermined value and the fuel command increase by more than a predetermined value. Symptom Probable Cause Analysis Repair Solution Combustion Ceases During Start-up Fuel Supply Fuel tank is empty or delivery tube not submersed in fuel. Fill Fuel Tank Fuel Not Turned On Check any externally installed fuel shutoffs to verify that fuel flow is obstructed. Open External Fuel Shutoffs Fuel BTU Content Dif- ferent Than What the System Expects System uses Fuel Index values adjustable by the user to compute mass flow of fuel. Wrong settings can cause inadequate levels of fuel flow to achieve combustion. Set Fuel Indices Adequate Fuel Pres- sure Not Provided to System Liquid fuel systems must have a positive fuel pressure provided to prevent air from getting into the fuel lines. Gaseous fuel systems (especially low BTU applications) require a minimum inlet pressure to achieve adequate fuel flow. Refer to System Specification to Adjust Fuel Pressure Unburned Fuel In Engine When excess fuel remains in the engine during lightoff, TETs can increase very rapidly. Fuel is then controlled to very low levels to reduce the initial TET increase. Sometimes fuel is reduced so far that a flameout occurs. Attempt Another Start Voltage Not Provided to Solenoids Check and verify that voltage is being provided to shutoff valves and manifold. Check/Replace Sole- noid Harness Fuel Shutoff Solenoid Failed Closed Inlet pressure droops significantly on start-up indicating that fuel has been cut off. Replace Fuel Shut- off Solenoid Fuel Manifold Sole- noids Failed Closed Exit pressure reading should be less than 10 psig during start.
