22.2.4.2 Display and operating unit AZL52, Software from V04.00 to V04.10

1. The unintentional safety shutdown with error code 16 if the permissible position
tolerances were not observed on reaching the low-fire position has been remedied.
This effect occurred mainly in very flat or very steep curve sections between the
ignition position and the low-fire position.
With the LMV52, this effect was remedied from software version 01.20 and with the
LMV51 from software version 02.50.
2. Monitoring of the microprocessor's power supply is now more tolerant.
3. Error code 1E, diagnostic code 10, after standardization of the VSD:
This error code occurred with ramp times above 35 seconds. The problem has been
eliminated.
4. Change of load controller mode 6 to 2: The output can now be changed.
5. VSD 0% with prepurging: Smallest adjustable value has been changed to 10%
speed.
6. VSD correction with speed deviations has been changed.
7. Using the PC software, a parameter set can now be stored in a new LMV5
8. Modbus setpoint W3 (writing after reset) has been corrected.

22.2.4.3 Display and operating unit AZL52, Software from V04.10 to V04.20

1. Display of additional temperature for steam plants with thermal shock protection.
2. The system is now capable of handling imperial and metric units.
3. The Siemens AZL52 is supplied with English settings.
4. Modbus: The nonresettable fuel meters have been replaced by resettable ones.
Following new parameters are now available:
- Temperature acquired by the extra temperature sensor for overtemperature
protection
- Flame signal (LMV51) / flame signal channel A (LMV52)
- Flame signal channel B (LMV52)
