22.2.4.5 Display and operating unit AZL52, Software from V04.30 to V04.50

1. Presentation of load controller's switching thresholds in absolute values.
But the setting values are still relative values.
2. ABmaxLoadMod is now limited by MinLoad and MaxLoad.
3. Correction of Italian translation.
4. Transmission of pressure values via eBus has been corrected.
5. Access level of activation parameter for the flame detector test has been changed
to AB.
6. Introduction of parameter StartPoint Op.

22.2.4.6 Display and operating unit AZL52, Software from V04.50 to V04.60

Effect of Error message 3163 in communication with ACS450 has been rectified.

22.2.4.7 Display and operating unit AZL52, Software from V04.60 to V04.80

1. Changes in connection with the new LMV5 version LMV52.4
General
In connection with the new LMV52.4, only the new AZL52 with software version
V04.80 can be used.
This AZL52 can also be used with all other types of LMV5.
Due to the new parameters, the initially reserved storage space in the AZL52 has
been exceeded ⇓ this has been rectified; for this reason, specific product nos.
(ASN) had to be introduced for the LMV52.4.
- Change to function Modulating curve parameterization.
The temperature currently acquired by the flue gas recirculation (FGR) sensor is
displayed if the flue gas recirculation (FGR) function is activated and auxiliary
actuator 3 has been selected for making the setting
- New function: Reading and display of stored curves of the flue gas recirculation
(FGR) temperatures OperationTempGas and OperationTempOil
- New function: Reading and display of temperature currently acquired by the flue
gas recirculation sensor, provided the AZL5 operates in interface mode. This is
provided because the value is not displayed by the PC software ACS450
- New function: Support of the new flue gas recirculation (FGR) parameters
- Compatibility: The new AZL52 accepts backup data from older software versions
– both AZL52 and ACS450 backups
- Name changes: For settings for the operating mode Flue Gas Recirc.
To avoid misunderstanding, 2 names have been changed:
1. deactivated in Aux3onCurve
Explanation:
When this operating mode is selected, the flue gas recirculation (FGR) function
is deactivated, auxiliary actuator 3 is used as the standard actuator and is driven
to the ratio control curve. This means that if, on this application, auxiliary
actuator 3 was used as a flue gas feedback actuator, flue gas would be
recirculated.
2. Hilf3 Minpos in deactMinpos
Explanation:
Since the word deact was replaced by Aux3onCurve (see 1.), the word deact
is added here. This denotes that auxiliary actuator 3 is driven to the minimum
position so that no flue gas is recirculated – or only very small amounts.
2. Further change.
New function: The cold start thermal shock ON and OFF values are now also
displayed as absolute values – in addition to the relative values.
