The following EID codes are covered by this procedure:
- EID 137 FMI F11 - Left Ext. Lost Flame Det.
- EID 141 FMI F11 - Left Main Lost Flame Det.
- EID 145 FMI F11 - Right Ext. Lost Flame Det.
- EID 159 FMI F11 - Right Main Lost Flame Det.
EID codes are issued for events that are not within the normal operation of the system. These events usually are not diagnosed as being a problem with any one system component. While these events are not within normal operation of the Burner Electronic Control, they may occur occasionally. If the events occur occasionally and are easily corrected, usually this is not considered to be a problem. No components need to be replaced. If these events occur frequently, then the cause of the problem should be investigated and corrected.
A "Lost Flame Det." EID FMI F11 diagnostic is recorded when a flame has been detected during the burner cycle, but is no longer detected when it should be. Refer to the Systems Operation, "Burner Control" modules in this manual for the correct sequence of events for the burner cycle.
The results of this active event code are:
- The burner diagnostic lamp, located beneath the screed walkway, is ON.
- The burner that is associated with the EID will turn OFF. After 5 minutes, the ECM will attempt the ignition cycle again when the burner mode switch is in AUTO mode and the screed plate temperature is low.
- The diagnostic lamp will stay On as until the burner has ignited successfully.
The possible causes of this active event code are:
- The tractor is out of fuel.
- The fuel filter is clogged.
- The fuel line to the screed has become detached or is clogged.
- The fuel pump has malfunctioned.
- The flame sensor for the burner associated with the EID has malfunctioned.
- The fuel solenoid for the burner associated with EID has malfunctioned.
- The ECM has malfunctioned. This is unlikely.
Perform the following procedure when this EID is active.
Test Step 1. Check Burner Operation
This step will check the operation of the burner.
- Turn the key start switch to the ON position.
- Turn the burner system switch to the BURNER position and move the burner mode switch for the involved burner from the OFF position to the AUTO position.
- Allow the ECM to initiate the burner ignite cycle and let the burner operate until the ECM turns the burner OFF. The ECM should shut down the burner when the proper screed plate temperature is reached or when the burner has operated for 20 minutes.
Expected Result:
The burner operated correctly and no diagnostic codes were activated.
Results:
- OK - The burner is operating correctly at this time. If this EID is activated frequently, proceed to the next step. Stop.
- NOT OK - The burner is not operating correctly. The burner has gone out after operating for a period of time. There may be a problem with the fuel system. Proceed to Step 2.
- NOT OK - If the burner has stayed ON and the "Lost Flame Det." EID code is still active, the flame sensor is malfunctioning.
Repair: Replace the flame sensor. If it is not possible to replace the flame sensor at this time, the burner can be operated in the MANUAL mode. When operating the burner in the MANUAL mode, the operator MUST ensure that the burner ignites. In Manual mode, the fuel will continue to be sprayed into the burner chamber regardless of whether the burner has ignited or not. Replace the flame sensor at the earliest possible time.
Stop.
Test Step 2. Check Fuel System
- Ensure that the machine is not out of fuel.
- Check the fuel filter to make sure it is not plugged.
- Ensure that the screed fuel line is properly connected to the main fuel line.
- Use the SPRAY mode in order to see that the fuel pump is working correctly.
Expected Result:
All of the above listed components for the fuel system have been checked and are working correctly.
Results:
- YES - All listed fuel system components are working correctly.
Repair: The fuel solenoid for the involved burner may not be working correctly. Remove and clean the fuel valve solenoid. Try to cycle the burner again. If the problem remains, check to see if any diagnostic codes are present for the fuel valve solenoid. If no diagnostic codes are present, replace the fuel valve solenoid.
Stop.
- NO - When the system is operated in the SPRAY mode, no fuel is present at the spray hose.
Repair: The fuel pump is not working. Either the fuel pump circuit or the fuel pump is malfunctioning. Use the Electrical System Schematic for your machine to troubleshoot the fuel pump circuit. Repair the fuel pump circuit or replace the fuel pump.
Stop.
