29 Revision history of basic unit
LMV37.4...
Software version V01.20
• Optimizations regarding ACS410 (backup / restore)
• Faster parameterization with AZL2… (3-stage)
• Burner identification setting (entering the password)
• Optimization “System 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 ampli-
fier
• 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 basic unit
and data set are identical
• Optimization: Alarm in the event of start prevention after a fixed time of 5 sec-
onds
• Extension: Selection of POC function or Pmax
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
