2.3 General information
The burner management system is operated and parameterized either via the AZL2
display and operating unit or with the help of the PC software ACS410.
The AZL2 with LCD and menu-driven operation facilitates straightforward use and
targeted diagnostics. When making diagnostics, the display shows the operating states,
the type of error and the point in time the error occurred. Passwords protect the different
parameter levels of the burner / boiler manufacturer and heating engineer against
unauthorized access.
There is also a COM port which can be accessed from a superposed system, such as a
building automation system.
On the BCI interface via interface OCI410, a PC can be connected with the PC software
ACS410 (for dual fuel operation on request).
Among other features, the PC software ACS410 enables convenient readout of settings
and operating states, parameterization of the LMV37.4 and trend recordings.
The burner / boiler manufacturer can select from different types of fuel trains and make
use of a wide choice of individual parameter settings (program times, configuration of
inputs / outputs, etc.), enabling him to make optimum adaptations to the relevant
application. The actuators are driven by stepper motors and can be positioned with high
resolution. Specific features and actuator settings are defined by the LMV37.4.
