Any # Referencing error on actuators
All SQM33… actuators must travel outside of their 0-90° operating range before starting up
the burner in order to "reference" their position. This fault means that the referencing was
unsuccessful.
1) Check the setting of parameter 601 (fuel 0) and 608 (fuel 1). Index 00 sets the fuel
actuator reference direction and index 01 sets the air actuator reference direction.
2) Check to make sure the actuators are not binding when trying to reference (ensure that
overstroking below 0° or above 90° is possible).
3) Check the setting of parameter 613 (fuel 0) and 614 (fuel 1) to ensure the actuator type
is set correctly.
4) Make sure that the actuator's are plugged into the correct terminal on the LMV3.

Referencing error due to parameter
change
86
Any # Error fuel actuator An error occurred pertaining to the fuel actuator. See diagnostic codes for more information.
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. Fix the wiring error
and reset the fault. 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.
87
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
If the fault occurs continuously, replace the LMV3.
91 Any # Internal error basic unit
93
Any # Error flame signal acquisition
Check the wiring of the QRB… flame detector and reset the fault. If the fault occurs
continuously, replace the QRB… flame detector.
