The burner management system is operated and programmed with the help of the
display and operating unit AZL5... or a PC tool.
The AZL5… with LCD cleartext and menu-driven operation affords straightforward
operation and targeted diagnoses.
For making diagnoses, the LCD shows the operating states, the type of fault and the
point in time the fault occurred.
The parameter setting levels for the burner / boiler manufacturer and heating engineer
are password-protected to prevent unauthorized access.
Basic settings that the plant operator can make on site do not demand a password.
Also, the AZL5... is used as an interface for superposed systems such as a building
management systems, or for a PC using the ACS450 software.
Among other things, the unit affords convenient readout of settings and operating
states, parameterization of the LMV5..., and trend recording.
When replacing the LMV5... basic unit (BU), all parameters can be saved in a backup
memory of the AZL5... to be loaded back into the basic unit.
This means that reprogramming is not required.
When designing the fuel trains, the burner / boiler manufacturer can choose from a total
of 7 valve families. The large number of individual parameterization choices (program
times, configuration of inputs / outputs, etc.) enable him to make optimum adaptations
to the specific application.
The universal SQM4... actuators are driven by stepper motors and can be positioned
with a high resolution. The characteristics and settings of the actuators are defined by
the basic unit of the LMV5... .
