30 Revision history of LMV37.4

Software version V01.20

Optimizations regarding ACS410 (backup / restore)

Faster parameterization with AZL2 (3-stage)

Burner identification setting (entering the password)

Optimization: LMV37.4 hooks itself up in phase 38
 Optimization: Cold setting via P0 (adoption P0  P1, correct CALC function)

Optimization: Delete history (acknowledgement upon completion)

Prepurging oil – activated / deactivated (parameter 262) for OEM level released

Setting range of pulse valency fuel meter (parameter 128) increased to 400
pulses per volume unit

New parameter 645 = configuration analog output
Software version V01.30

Optimization of phase manager (rectification of error 107)

Presetting of parameter 281 (time oil ignition) changed to long preignition (with fan)
Software version V01.40

Optimization: Modbus mode and operating mode are maintained when a reset is
made

Extension: Additional Modbus addresses (refer to Modbus Documentation A7541)

Extension: Actuator tolerance can be parameterized by OEM and read by the
heating engineer

Change: The heating engineer can set the time when valve proving takes place

Extension: Calculation of fuel throughput

Optimization: Plausibility check for continuous operation with ionization amplifier

Optimization: Separate diagnostic code in the event standardization has not been
successful due to an undefined operating mode

Optimization: Change of password without having to enter the currently valid
password

Extension: Restore of data set possible only when type references of LMV37.4 and
data set are identical

Optimization: Alarm in the event of start prevention after a fixed time of 5 seconds

Extension: Selection of POC function or Pressure switch-max
Software version V01.60

Optimization: Filtering of analog power output

Optimization: Plausibility check of ionization amplifier revised
Software version V01.70
Optimization: Final test sequence revised.
Software version V01.80

Optimization: Valve proving during shutdown after display error in operation

Optimization: Any valve proving aborted by Pressure switch-min during shutdown is
repeated with the next startup
