Burner Management System for forced draft burners with load control

LMV51.100C2 is a microprocessor-based burner management system with matching system components for the control and supervision of forced draft burners of medium to high capacity


The LMV5 is operated and programmed with the help of the AZL5 or PC software. The AZL5 with LCD clear text and menu-driven operation affords straightforward operation and targeted diagnostics.

For diagnostics, 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 unauthorised access.

Basic settings that the plant operator can make on site do not require a password. Also, the AZL5 is used as an interface for superposed systems such as a building automation and control system (BACS), or for a PC using the ACS450 software.

Among other features, the unit affords convenient readout of settings and operating states, parameterisation of the LMV5, and trend recording. When replacing the LMV5, all parameters can be saved in a backup memory of the AZL5 to be loaded back into the LMV5. 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 parameterisation choices (program times, configuration of inputs / outputs, etc.) enable him to make optimum adaptions to the specific application.

The universal SQM4 / SQM9 actuators are driven by stepper motors and can be positioned with high resolution. The characteristics and settings of the actuators are defined by the LMV5.
