Description

The LMV26 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.

Application areas
The LMV26 air-fuel ratio controls the system is used for the control of modulating or multi-stage oil or gas burners of medium capacity. A simple user and service-friendly interface with LCD enables the LMV26 to be commissioned quickly and ensures efficient and cost-saving maintenance of the entire system. The benefits offered by electronic air-fuel ratio control are independent
ratio curve settings and flexibility in terms of burner design. Fuel and air actuators can be fitted anywhere without having to give consideration to mechanical linkage.

Optimum conditions
Key components of the LMV26 system are the SQM3 and SQN1 actuators. They ensure accurate positioning of the air and fuel dampers, thus warranting optimum combustion with low emission levels. Variable actuator running times provide for a quick start-up when there is a request for heat and good control performance in modulating mode.

Simplified design
The burner management system brings its benefits into play not only in operation but also during the development and design phase of new generations of burner: The LMV26 has the burner control, electronic ratio control and gas valve proving integrated into its basic unit.

Extremely straightforward
The LMV26 burner management system not only simplifies burner design but also makes the production process, mounting and service work more efficient: The complex linkage required with mechanical air-fuel ratio control is no longer needed and flexibility is increased considerably when using the basic unit. Depending on the individual unit versions, the LMV26 burner management system provides a number of variable program sequences for control of the burner. There is a choice of gas and oil programs, with or without a pilot burner, depending on the application and the basic unit version. Even dual-fuel applications with the AGM60 fuel changeover unit is possible.

Extra functions
For a quick burner commissioning, the gas valve proving can be optionally activated during post purging. Operation with only one actuator for pneumatic air-fuel ratio control is possible also. Furthermore, the extensive choice of configurations and parameter settings enables the LMV26 to be matched to almost any type of medium-capacity burner – easily and efficiently.
The LMV26 is approved for continuous operation with the ionization probe, enabling it to be used also in connection with steam boilers or in plants for generating process heat. The LMV26 system is designed for mounting on the burner itself or adjacent to the burner components.
