1 Safety notes
1.1 Warnings
Observe the following warning notes to help prevent damage to persons,
property or the environment!
The LMV5... is a safety device! Do not interfere with or modify the unit. Siemens
Landis & Staefa will not assume responsibility for damage resulting from
unauthorized interference!
The addendum to the LMV51.2... and LMV52... documentation contain additional
warning notes which should also be observed when using these system variants.
After commissioning and after each service visit, check the flue gas values
across the entire load range.
The present Basic Documentation describes a wide choice of applications and
functions and serves as a guideline. The correct functioning is to be checked and
proven with the help of functional tests on a test rig or on the plant itself!
•All activities (mounting, installation, service work, etc.) must be performed by
qualified staff
•Degree of protection IP40 as per DIN EN 60 529 for burner controls must be
ensured through adequate mounting by the burner or boiler manufacturer
•Before performing any work in the connection area of the LMV5…, disconnect the
unit from mains supply (all-polar disconnection)
•Protection against electrical shock hazard on the LMV5... and on all connected
electrical components must be ensured through appropriate mounting
•Check to ensure that wiring is in an orderly state
•Fall or shock can adversely affect the safety functions. Such units may not be put
into operation even if they do not exhibit any damage
•In programming mode, the position check of the actuators and of the VSD
(checking electronic fuel / air ratio control) is different from the check during
automatic operation. Like in automatic operation, the actuators are still jointly
driven to their required positions. If an actuator does not reach the required
position, corrections are made until that position is reached. However, in contrast to
automatic operation, there are no time limits for these corrective actions. The other
actuators maintain their positions until all actuators have reached their currently
required positions. This is essential for setting fuel /air ratio control. This means
that during the time the ratio curves are programmed, the person making the plant
settings must continuously monitor the quality of the combustion process (e.g. by
means of a flue gas analyzer). Also, if combustion levels are poor, or in the event
of dangerous situations, the commissioning engineer must take appropriate action
(e.g. switching the system off manually)
To ensure the safety and reliability of the LMV5... system, the following points must
also be observed:
-Condensation and ingress of humidity must be avoided. Should such conditions
occur, make sure that the unit will be completely dry again before switching on!
-Static charges must be avoided since they can damage the unit’s electronic
components when touched.
Recommendation: Use ESD equipment
1.2 Mounting notes
•Ensure that the relevant national safety regulations are complied with
•In the geographical areas where DIN regulations apply, the requirements of VDE
must be satisfied, especially the standards DIN / VDE 0100, 0550 and DIN / VDE
0722

15/278
Siemens Building Technologies Basic Documentation LMV51... CC1P7550en
HVAC Products 1 Safety notes 01.10.2003
1.3 Installation notes
•Ensure that the electrical wiring inside the boiler is in compliance with national and
local safety regulations
•Make certain that strain relief of the connected cables is in compliance with the
relevant standards (e.g. as per DIN EN 60730 and DIN EN 60 335)
•Ensure that spliced wires cannot get into contact with neighboring terminals. Use
adequate ferrules
•Lay the high voltage ignition cable completely separate from all other cables
•The burner manufacturer must protect unused AC 230 V terminals with a dummy
plug (refer to 2.2 Product range overview and 11.2 Suppliers of other accessory
items)
•When wiring the unit, ensure that AC 230 V mains voltage cables are run strictly
separate from extra low-voltage cables to warrant protection against electrical
shock hazard
1.4 Electrical connection of ionization probe and
flame detector
It is important to achieve practically disturbance- and loss-free signal transmission:
•Never run the detector cables together with other cables
– Line capacitance reduces the magnitude of the flame signal
– Use a separate cable
•Observe the permissible cable lengths
•The ionization probe is not protected against electrical shock hazard. The mains-
powered ionization probe must be protected against accidental contact
1.5 Commissioning notes
•Prior to commissioning, check to ensure that wiring is in an orderly state and that
the parameter are correctly set
•When commissioning the unit, check all safety functions
•There is no absolute protection against incorrect use of the RAST5 connectors. For
this reason, prior to commissioning the plant, check the correct assignment of all
connectors
•Electromagnetic emissions must be checked on an application-specific basis

HVAC Products 1 Safety notes 01.10.2003
1.6 Setting and parameter setting notes
•When adjusting the electronic fuel / air ratio control system integrated in the
LMV5…, allow for sufficient amounts of excess air since – over a period of time –
the flue gas settings will be affected by a number of factors (e.g. density of air,
wear of the actuating devices, etc.). For this reason, the flue gas values initially set
must be checked at regular intervals
•To provide protection against inadvertent or unauthorized parameter transmission
between the parameter backup memory of the AZL5... display and operating unit
and the LMV5... basic unit, the OEM ¹) must enter an individual burner identification
(ID) for each burner. Compliance with this regulation is mandatory to ensure that
the LMV5… system will prevent parameter sets from other plant (with unsuited and
possibly dangerous parameter values) to be transmitted to the LMV5… basic unit
via the backup memory of the AZL5... (also refer to the description of burner
identification in chapter 7 Display and operating unit AZL5...)
¹) OEM = burner or boiler manufacturer
•With the LMV5..., it is to be noted that the unit’s characteristics are determined
primarily by the specific parameter settings rather than by the type of unit. This
means that, among other things, each time a plant is commissioned, the parameter
settings must be checked and the LMV5... may not be transferred from one plant to
another without adapting the parameter settings to the new plant
•In the case of dual-fuel burners and oil-firing, the short preignition (Phase 38)
parameter OnTmeOilIgnition is to be selected and a magnetic clutch is to be used,
thus ensuring that there will be no oil pressure until this phase is reached. Then,
the long preignition (from Phase 22) must be parameterized
•When using the ACS450 PC software, the safety notes given in the relevant
Operating Instructions (CC1J7550) must also be observed
•A password protects the parameter setting level against unauthorized access. The
OEM allocates individual passwords to the setting levels he can access. The
standard passwords used by Siemens Landis & Staefa must be changed by the
OEM. These passwords are confidential and may only be passed on to persons
authorized to access such setting levels
•The responsibility for setting the parameters lies with the person who – in
accordance with his access rights – has made changes to the respective setting
level
In particular, the OEM will assume responsibility for the correct parameter
settings in compliance with the standards covering the specific applications (e.g.
EN 676, EN 267, EN 1643, etc.).

1.7 Norms and standards
•Conformity with EEC directives
– Electromagnetic compatibility EMC (immunity) 89 / 336 EEC
– Directive for gas appliances 90 / 396 EEC
– Low-voltage directive 73 / 23 EEC
1.8 Service notes
•Each time a unit has been replaced, check to ensure that wiring is in an orderly
state
•If fuses are blown, return the complete unit to Siemens Landis & Staefa
1.9 Disposal notes
The unit contains electrical and electronic components and may not be disposed of
together with household waste. Legal and currently valid legislation must be observed.

2.1 Brief description
The LMV5... is a microprocessor-based burner management system with matching
system components for the control and supervision of forced draft burners of medium to
large capacity.
The following components are integrated in the basic unit of the LMV5...:
•Burner control with gas valve proving system
•Electronic fuel / air ratio control system for a maximum of 4 actuators
•Optional PID temperature / pressure controller (load controller)
•VSD module
The system components (display and operating unit AZL5..., actuators, O2 module,
etc.) are interconnected via a bus system. Communication between the individual CAN
bus users takes place via a reliable, system-based data bus.
The safety concept makes use of 2 microprocessors for 2-channel signal processing.
It offers a very high level of safety and reliability for monitoring the software and the
program and control sequences.
All safety-related digital outputs of the system are permanently monitored via a contact
feedback network.
For flame supervision in connection with the LMV5..., universal infrared flame detectors
type QRI... or ionization probes can be used for continuous operation, and photoresistive
flame detectors type QRB... for intermittent operation.
Example: Dual-fuel burner
- Gas: Modulating
- Oil: 2-stage

HVAC Products 2 General 01.10.2003
The burner management system is operated and programmed with the help of the
display and operating unit AZL5... or a PC tool.
The AZL5… with LCD cleartext and menu-driven operation affords straightforward
operation and targeted diagnoses.
For making diagnoses, 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 unauthorized access.
Basic settings that the plant operator can make on site do not demand a password.
Also, the AZL5... is used as an interface for superposed systems such as a building
management systems, or for a PC using the ACS450 software.
Among other things, the unit affords convenient readout of settings and operating
states, parameterization of the LMV5..., and trend recording.
When replacing the LMV5... basic unit (BU), all parameters can be saved in a backup
memory of the AZL5... to be loaded back into the basic unit.
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 parameterization choices (program
times, configuration of inputs / outputs, etc.) enable him to make optimum adaptations
to the specific application.
The universal SQM4... actuators are driven by stepper motors and can be positioned
with a high resolution. The characteristics and settings of the actuators are defined by
the basic unit of the LMV5... .
