LMV52 Software Update: Version 0130 to 0410 (continued)
6. The inputs for oil are no longer checked when firing on gas. Likewise, the inputs for gas are
no longer checked when firing on oil.
7. The maximum filling and evacuation times for gas valve proving are now limited by the
maximum permissible safety time for startup. In particular, this affects the burner control
versions that use the American standard parameter set.
8. Introduction of max. load limitation at the user level ( UserMaxLoadMod , UserMaxLoadStg ).
9. Hiding an adjustable load range aimed at reducing resonance phenomena in the
burner/boiler/stack system (
LoadMaskLowLimit , LoadMaskHighLimit ).
10. The fuel actuator can be deactivated (only with an LMV52).
11. A new flue gas recirculation (FGR) function (only with an LMV52). Actuator AUX3 can be
employed for controlling the damper used for flue gas recirculation (FGR). To improve the
burner’s startup characteristics, only this actuator can be driven from its ignition position to the
adjusted curve, either time-delayed or depending on the flue gas temperature.
12. A new option for no prepurge for gas burners ( Skip Prepurge Gas ). As per EN 676, the
prepurge time can be skipped if a valve proving system is installed.
13. Changing the extraneous light test for OEMs. Now the OEM is able to skip the extraneous
light test in the start sequence (
ExtranLightTest ).
14. The curve points can now be adjusted without actually running the actuators to the
adjusted positions.
15. When running heavy oil, the high oil pressure switch can now be opened in phases 38 and
44 for the pressure switch reaction time.
LMV52 Software Update: Version 0410 to 0420
The following updates were made with LMV52 software version 0420:
1. Check of AZL5 software version changed to version 0360 or higher.
2. Handling of open / closed release contact changed.
3. O

sensor test delayed until test conditions are reached.
4. Plausibility check of run time test rectified.
5. Timing problem in connection with flying start of VSD rectified.
