Section 1 Overview
Introduction 1-1
The Siemens LMV5 Burner Management System (BMS) combines the functionalities of a flame
safeguard and a fuel-air ratio control when it is used in it’s most simple form.
This BMS is modular, and can be expanded to encompass features such as load control, integrated
O2 trim, Variable Speed Drive (VSD), fuel usage monitoring, efficiency monitoring, simultaneous
operation of 5 rotary actuators, Lead / Lag control, Touch Screen Human Machine Interfaces (HMI),
ModBUS communications and other advanced features.
These features make the LMV5 extremely flexible, and ideally suited for use with most steam
boilers, hot water boilers, thermal fluid heaters, and industrial burners.

Display Options
AZL52.40B1 Backlit display connects to the base unit via a 9 pin cable using
CANbus protocol and is required for operation of the base unit.
ModBUS communication via an RJ45 female jack on
the back of the display, using RS-232 protocol, is standard.
One AZL is necessary for each burner.
HMI (Human Machine Interface) Touch Screen display
communicates to the required AZL5 via ModBUS
communications.
The HMI can provide lead / lag control, trending, internet
communications, and boiler room efficiency optimization
in addition to many other advanced features.
One HMI can be used to interface with multiple AZL5s.
The HMI is not necessary for operation of the base unit.
