31 Revision history of basic unit LMV36...

Software version V03.00

Optimization: Maximum time of safety phase reduced from 28 to 27 seconds

Optimization: Correction of error diagnostics C:61 D:0 or 1 (Fuel Chg)

Optimization: No error Fuel Err when pressing the reset button for a short moment
after a reset / power-on

Parameter 376: Deactivation of oil pressure switch-min for fuel 1
Software version V03.10

Optimization: If power supply fails during the restore process, the data set can be
repaired by starting a new restore process (since the backup / restore option is not
yet available with V03.00 because there is no suitable AZL2..., this effect cannot
occur)

Optimization: If the analog input is interrupted, error C:60 (no valid output source) is
canceled or reset when Default output low-fire is parameterized (only with LMV36...)

Optimization: When making a reset via the AZL2..., an incomplete reset occurred in
very rare cases (display showed RESEt, but reset was not triggered)

Optimization: The time of 0.2 seconds ascertained by the loss-of-flame test was too
long

Optimization: No continuous purging with the LMV36... (in prepurge / ignition
position) during the gas shortage waiting time when using a VSD and valve proving
via gas pressure switch-min

Optimization: With fuel changeover, error codes C:85 / C:86 do not occur any more

Optimization: Reduced detection of undervoltage when fan motor is started in phase
22 (when a single-phase motor and the LMV3 120 V were powered via the same
phase, undervoltage detection could occur on startup; in that case, the LMV3
system was not operated as specified)

Optimization: Better overview through text changes of groups 200 = PAr0, 300 =
PAr1 and 600 = ACtr on the parameter menu (initially PArA), and hiding of unused
parameters after selection of fuel train / operating mode (no display of oil
parameters in gas fuel train)

Optimization: Control of the fan output during standardization (standby) for using a
release contact via an external relay at the fan's output

Optimization: Curve setting invalid (OFF UPr) after new / further standardization

Optimization: To shorten the startup time, there is no referencing when postpurging
is aborted via controller-ON (direct start)

Automatic return travel of the SQN1... at the lower internal stop

Parameter on Siemens level
Longer ignition off time during safety time 1 (TSA1) (increased from 0.4 to 0.6
seconds) to prevent wrong error diagnostics in connection with QRA2... (C:7 in
place of C:2)

Parameter at the Siemens level:
Readjustment of threshold for detection of interruption based on operation with
AGM60... and 2 fuel actuators

Creation of new parameter sets for the burner output test based on V01.05
(otherwise, due to a restore process with old data sets during the burner output test,
parameter changes at the safety limit thermostat level might be overwritten again)
Software version V03.30

Extension: Display of intensity of flame when setting the curves

Optimization: Display and diagnostics of changing start preventions

Optimization: No unplausible relay setpoint (error C:99 D:3) when starting
standardization, alarm in case of start prevention and controller-ON signal

Optimization: No VSD standardization with pneumatic air-fuel ratio control

Optimization: Referencing in connection with direction of rotation Right and home
position 90°

Extension: Separate pressure switch valve proving via X5-02 (Pmax / POC)
