LMV52 Software Update: Version 0450 to 0480 (continued)
8. A parasitic effect in the QRI2 flame scanner during the reset phase leads to a short signal
pulse. Thus, flame evaluation during the reset is now delayed so the signal is ignored.
The following updates were made with LMV52 software version 0510:
1. A new option for flame supervision via an external, safety-related flame safeguard.
2. Continuous pilot is available for fuel trains using a pilot. If activated, the pilot valve remains
open through phase 62.
3. A new calculation process is available for O
was enhanced to include the "LambdaFact1" setting option.
4. When setting the O

been reduced as follows:
• Interval between O
• Interval between O
5. In O operating mode "conAutoDeac", when the O

initially operates along the ratio control curves. O
automatically once the NumMinUntilDeact repetition counter has elapsed. The minimum O
alarm remains active even once O
6. Omission of the waiting time following interruptions to the power supply if the QGO20 cell
temperature is greater than 1274 °F [690 °C] on startup.
7. O trim control behavior can be altered using the O2TrimBehavior parameter.

11. The O maximum value alarm has been revised. It can now be the O

a set value. This is programmed via parameters Type O2 MaxValue and O2 MaxValue.
12. A new service timer for the O
O2SensServTim and reset via parameter O2SensServTimRes.
13. In order to calculate the combustion efficiency, the supply air temperature sensor can now
be connected to input X60 as well as to input X87 on the PLL52 which was already available.
