Error
Code
Diag.
Code
Meaning for the LMV3 Corrective Action
Note: Diagnostic codes are additive. If a diagnostic code appears that is not on this list, it is a combination of multiple diagnostic codes.
0 Position error
Verify that the valve connected to the fuel actuator is not bound. Ensure
that the torque requirements of the valve are less than the output of the
fuel actuator. If everything checks out okay, replace the SQM33 actuator.
1 Line interruption
Check the wiring between the fuel actuator and LMV3 terminal X54.
There should more > 0.5 VDC across pins 2 and 5 and across pins 2 and 6.
If no fuel actuator exists, choose a fuel train option (parameter 201/301)
that does not require a fuel actuator.
8 Curve too steep in terms of ramp rate See error code 84.
86 16 Step deviation in comparison with last referencing
The fuel actuator is bound.
1) Check the setting of parameter 613:00 (fuel 0) and 614 (fuel 1) to
ensure the actuator type is set correctly.
2) Check to see if the actuator gets bound somewhere along its working
range. This can be done changing the home position of the actuator in
standby (no alarm).
3) Ensure that the torque of the actuator is sufficient for the application.
Any # Error air actuator
An error occurred pertaining to the air actuator. See diagnostic codes for
more information.
0 Position error
Verify that the valve / damper connected to the air actuator is not bound.
Ensure that the torque requirements of the valve / damper are less than
the output of the air actuator. If everything checks out okay, replace the
SQM33 actuator.
1 Line interruption
Check the wiring between the air actuator and LMV3 terminal X53. There
should more > 0.5 VDC across pins 2 and 5 and across pins 2 and 6. If no
air actuator exists, choose a fuel train option (parameter 201/301) that
does not require an air actuator.

Any # Error flame signal acquisition
3 Short-circuit of sensor
86
Check the wiring of the QRB… flame detector and reset the fault. If the
fault occurs continuously, replace the QRB… flame detector.
