Meaning for the LMV3 System 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.
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).
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. Fix the
wiring error and reset the fault. If no air actuator exists, choose a fuel
train option (parameter 201/301) that does not require an air actuator.
8 Curve too steep in terms of ramp rate See error code 84.
16 Step deviation in comparison with last referencing
The air actuator is bound.
1) Check the setting of parameter 613:01 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.
90 Any # Internal error basic unit
91 Any # Internal error basic unit
Any # Error flame signal acquisition
3 Short-circuit of sensor

If the fault occurs continuously, replace the LMV3.
Check the wiring of the QRB… flame detector and reset the fault. If the
fault occurs continuously, replace the QRB… flame detector.
