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.

Important Safety Notes 1 - 4
The LMV5 is a safety device. Under no circumstances should the unit be modified or opened.
Siemens Building Technologies, Inc. will not assume responsibility for damage resulting from
unauthorized modification of the unit.
After commissioning, and after each service visit, the flue gas values should be checked across
the firing range.
All activities (mounting, installation, service work. etc.) must be performed by qualified staff.
Before performing any work in the connection area of the LMV5, disconnect the unit from the
main supply (all-polar disconnection).
Protection against electrical shock hazard on the LMV5, and on all connected electrical
components must be ensured through good wiring and grounding practices.
Fall or shock can adversely affect the safety functions of an LMV5. Such units must not be put
into operation, even if they do not exhibit any apparent damage.
When the LMV5 is running in automatic mode, actuators are continuously monitored by the
LMV5.
During commissioning, when the ratio-control curves are being set, the actuator positions are
NOT continuously monitored by the LMV5.
The technician is solely responsible for verifying the correct position of each actuator during the
ratio-control curve commissioning.
The coupling that is used between the actuator and the driven valve / damper is safety related,
and must be of a robust and flexible design. Should this coupling fail during operation, the LMV5
will no longer have control of the burner’s combustion bringing about a hazardous condition.
Condensation and the entry of water into the unit must be avoided.

Section 2 Mounting
LMV5 Base Unit 2-1
The base unit should be mounted inside an enclosure that will protect the LMV5 from dirt and
moisture. The unit is mounted by four screws that are captive in each corner, and have an M5
thread. The mounting plate that the unit sits on should be drilled and tapped to accommodate these
screws. It should be noted that the mounting screws do not have excessive play, so the spacing of
the mounting holes must be accurate. This can be easily achieved by placing the LMV5 in the
desired position and turning each of the mounting screws to mark the plate that the LMV5 will be
mounted to.
During the mounting process, consideration should also be given to the various plugs and wires that
must be attached to the LMV5. Electrical connections are made via plugs that are located in the
face, top and bottom of the unit. A space of at least two inches is recommended on the top of an
LMV51, and the top and bottom of an LMV52.
Please see Section 10 for specifications.
Figure 2-1.1 LMV5 Base Unit Dimensions (inches)

LMV5 QSG Rev 4 Sec 2 Pg 2 www.scccombustion.com
AZL5 Display 2-2
The AZL5 is designed to be mounted through the face of an electrical enclosure. This is
accomplished by an accurate cut-out, which is usually in the door of the enclosure. The AZL5 has
one screw on the top and one on the bottom that engage small plastic tabs that will swing out and
pull to the front when the screw is tightened, and will retract and push to the back when loosened.
This facilitates easy removal and replacement of the AZL5 since it is designed to be taken out of the
enclosure face and held in the hands for set up / commissioning. When properly installed, the AZL5
will hold the sheet metal of the enclosure between the plastic tabs and ridge which holds the AZL5
to the enclosure gasket.
The connector shown in Figure 2-2.1 is for the connection of a laptop computer.
Note that the CANbus connector, (not shown) plugs into the bottom of the AZL5. The CANbus
connector would not be seen from the front when the AZL5 is mounted, but does require
approximately 2.5” below the bottom of the AZL5 to clear the connector and the CANbus cable.
Please see Section 10-1 for specifications.
Figure 2-2.1 AZL5 Dimensions (inches)

LMV5 QSG Rev 4 Sec 2 Pg 3 www.scccombustion.com
SQM4x Actuators 2-3
The SQM4x actuators that are driven by the LMV5 come in three basic torques and running times
as described in the product offering. See Section 1-2.
Actuators can rotate clockwise or counterclockwise depending upon programming in the LMV5.
All actuators share the same mounting hole pattern. The SQM48.4 and SQM48.6 both have 14mm
keyed shafts, the SQM45’s both have 10mm shafts, 291A9 is keyed, 295A9 is “D” shaped.
The actuator body should be rigidly attached to the driven valve or damper utilizing the supplied
mounting holes. The actuator shaft should be attached to the valve or damper via an SCC Inc.
robust, zero lash flexible coupling.
Shaft couplings are safety related, since a coupling failure could let the valve / damper spin freely of
the actuator. Brackets and couplings specifically designed to attach these actuators to valves
and dampers are available, and are highly recommended.
Please speak to a SCC Inc. sales representative concerning these brackets and couplings.
Please see Section 10-1 for specifications.
Figure 2-3.1 SQM4x Dimensions (inches)
IMPORTANT: Coupling set screws should not be tightened on the valve / damper shaft until:
1) Actuators are addressed and rotations are set in the LMV5
2) Each actuator is verified to be at zero degrees (closed)
This verification should be done under:
Parameters & Display > Ratio Control > Gas/Oil Settings > Curve Parameters.
3) Each valve / damper is verified to be closed, thus matching the indicated actuator position.

LMV5 QSG Rev 4 Sec 2 Pg 4 www.scccombustion.com
Accessories 2-4
AGG5.210 Transformer(s)
The AGG5.210 transformer supplies 12 VAC power to the LMV5 base unit, AZL5, actuators, and
PLL52 (if equipped). This transformer should also be mounted in an enclosure that shields the
transformer from dirt and water. At least one transformer is necessary for each LMV5 base unit.
Depending upon how many devices are connected to the CANbus, (actuators, PLL52 module, etc)
two AGG5.210 transformers may be necessary.
Note: If a second transformer is used, locate it as close as possible to the actuators / PLL52
that it powers.
Section 3-1, Figure 3-1.4 outlines when two transformers should be used.
Figure 2-4.1 gives the dimensions of a AGG5.210 transformer. The transformer may be mounted
with the plugs facing downward or upward. Oval holes are provided for use with self tapping or
machine screws.
Please see Section 10-1 for specifications.
