2 System structure / function description
The LMV27 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.
In the LMV27 are integrated:
Burner management system complete with valve proving system
Electronic air-fuel ratio control system for a maximum of 2 SQM3 or SQN1
actuators
Modbus interface
Figure 4: System structure
Example: Modulating gas burner
The system components (AZL2, actuators) are connected directly to the LMV27. All
safety-related digital inputs and outputs of the LMV27 are monitored by a contact
feedback network.
The diagram shows the full scope of functions of the LMV27. The actual functions are to
be determined based on the respective execution / configuration!
2.1 For Europe
For intermittent operation in connection with the LMV27, the ionization probe or the
QRA, QRB or QRC optical flame detectors can be used.
