2.2 General information

The burner management system is operated and parameterized either via the AZL2 or
with the help of the ACS410 PC software. 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 and control system (BACS).
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 ACS410 software affords convenient readout of settings and
operating states, parameterization of the LMV27, 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 LMV27.
