AZL5 Software Update: Version 0460 to 0480
The following updates were made with AZL5 software version 0480:
1. In connection with the new LMV52.4, only AZL5 units with software version 0480 and higher
can be used. The AZL5 can also be used with all other types of LMV5. Due to the new
parameters, the initially reserved storage space in the AZL5 had been exceeded. For this
reason, specific product numbers had to be introduced for the LMV52.4.
2. 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 the auxiliary 3 actuator has been selected for FGR.
3. New parameters OperationTempGas and OperationTempOil are available for reading and
displaying the recorded flue gas recirculation (FGR) temperatures during commissioning.
4. Reading and display of the temperature currently acquired by the flue gas recirculation (FGR)
sensor when the AZL5 is in interface mode. This is provided because the value is not displayed
by the PC tool ACS450.
5. Support of the new flue gas recirculation (FGR) parameters.
6. The AZL5 accepts backup data from older software versions (both AZL5 and ACS450
backups).
7. To avoid misunderstandings, two names have been changed for the FGR operating mode:
•
Aux3onCurve - When this operating mode is selected, the flue gas recirculation (FGR)
function is deactivated and the auxiliary 3 actuator is driven to the ratio control curve.
This means that if the auxiliary 3 actuator is used as a flue gas feedback actuator, flue
gas would be recirculated.
•
deactMinpos - Since the word deact was replaced by Aux3oncurve, the word deact is
added here. This denotes that the auxiliary 3 actuator is driven to the minimum position
so that no flue gas is recirculated (or only very small amounts).
8. The cold start thermal shock ON and OFF values are now also displayed as absolute values –
in addition to the relative values.
