5018 Internal Fault STUCK FUEL VLV Stuck Fuel Valve System Severity Level 3 The software performs a test during the prepare-to-start sequence to determine if the valve has failed in the open position. Open the manifold solenoids to purge fuel downstream of the proportional valve. Close the solenoids and capture the downstream pressure reading. With the proportional valve commanded closed, open the main fuel shutoff solenoid to allow fuel into the system. No fuel should pass through the proportional valve. Software verifies that no fuel has passed through the proportional valve by checking to see if the downstream pressure has increased. When the downstream pressure has increased 10 psig greater than the initial reading, a Stuck Fuel Valve fault is reported. Symptom Probable Cause Analysis Repair Solution Valve Does Not Maintain a DeltaP Across the Valve During Leak Check at Start. Fuel supply Logic uses pressure readings to verify valve is not stuck open. DeltaP read- ing is not accurately measured when no fuel is supplied. Verify proper fuel pressure is applied to the valve. Water in Transducer Harness In humid environments temperatures near the microturbine can reach the dew point. Water in the back of the connector will short the signal wires. Dry Pressure Harness Loose Transducer Connections Connections can come loose through handling of device or during compo- nent changing. Secure Pressure Har- ness at Inlet and Exit Transducer and at Fuel Controller. Debris in valve Valve can have debris that causes it to become temporarily stuck open. Lightly tap valve body and attempt restart. Fuel Control Valve Stuck Open Fault is continuously reported after several start attempts. Replace Fuel Control Valve Inlet Pressure Trans- ducer Reading Situation persists and inlet pressure is never measured during the start sequence. Replace Inlet Pressure Transducer Closed Fuel shutoff valve Inlet pressure is still not read during start sequence after inlet transducer is replaced. Replace Fuel Shutoff Valve Exit Pressure Trans- ducer Reading Situation persists and exit pressure never goes to zero during start sequence. Replace Exit Pressure Transducer Pressure Transducer Harness After replacing pressure transducers, pressure readings still do not provide correct readings during start. Replace pressure transducer harness.
