LMV52 Software Update: Version 0420 to 0450
The following updates were made with L
MV52 software version 0450:
1. Abortion of speed test during operation by leaving the left operating position with controlled
shutdown.
2. Implementation of functionality to reach the operating position after ignition via a curve
point other than point 1 (StartPoint Op).
3. No more writing of diagnostic data in the ignition phases (not yet implemented with the VSD
module).
4. Position evaluation of actuators and VSD in phases 20-22 removed.
5. Introduction of a timeout (ramp time) for opening the release contact when speed is not
reached in standby and home run.
6. Evaluation of extraneous light during shutdown in phase 76 (second part of afterburn time)
shifted.
7. Implementation of load adjustment with ExtR-X5 and the fuel actuator is deactivated.
8. Response of start prevention changed when alarms are activated in standby and the QGO20
is not up to temperature.
LMV52 Software Update: Version 0450 to 0480
The following updates were made with L
MV52 software version 0480:
1. Flame failure during safety time 2 (TSA2).
2. Message for flame failure during safety time 2 (TSA2) changed from “Loss of flame during
operation” to “No flame at the end of the safety time”.
3. In the case of fuel trains with direct ignition (G, LO, HO), phases 50 (TSA2) and 52 (interval 2)
are skipped.
4. Introduction of a minimum test time of 5 seconds for extraneous light during startup in
phase 36 (driving to ignition position).
5. In the case of a flying start, the VSD test is skipped.
6. Parameter MinLoadGas at the service level is valued higher than parameter
UserMaxLoadMod at the user level.
7. When deleting the curve parameters, StartPoint Operation, the value used for overwriting
parameters was too high. This has been rectified with version 4.80.
