Warning notes
For additional safety notes, refer to the Basic Documentation of the LMV5... sys-
tem (P7550)!
To avoid injury to persons, damage to property or the environment, the following
warning notes must be observed!
The LMV5... is a safety device! Do not open, interfere with or modify the unit.
Siemens will not assume responsibility for any damage resulting from unauthor-
ized interference!
•All activities (mounting, installation and service work, etc.) must be performed by
qualified staff
•Before making any wiring changes in the connection area of the LMV5..., com-
pletely isolate the plant from mains supply (all-polar disconnection). Ensure that the
plant cannot be inadvertently switched on again and that it is indeed dead. If not
observed, there is a risk of electric shock hazard
•Ensure protection against electric shock hazard by providing adequate protection
for the connection terminals and by securing the housing cover
•Each time work has been carried out (mounting, installation, service work, etc.),
check to ensure that wiring and parameterization is in an orderly state and make
the safety checks as described in «Commissioning notes»
•Fall or shock can adversely affect the safety functions. Such units must not be put
into operation, even if they do not exhibit any damage

Installation notes
•Always run high-voltage ignition cables separately while observing the greatest
possible distance to the unit and to other cables
•Do not mix up live and neutral conductors
Electrical connection of the flame detectors
It is important to achieve practically disturbance- and loss-free signal transmission:
•Never run the detector cable together with other cables
– Line capacitance reduces the magnitude of the flame signal
– Use a separate cable
•Observe the maximum permissible detector cable lengths
•The ionization probe is not protected against electric shock hazard. It is mains-
powered and must be protected against accidental contact
•Locate the ignition electrode and the ionization probe such that the ignition spark
cannot arc over to the ionization probe (risk of electrical overloads)

Service notes
•If fuses are blown, the unit must be returned to Siemens
Life cycle
Burner controls has a designed lifetime* of 250,000 burner startup cycles which, under
normal operating conditions in heating mode, correspond to approx. 10 years of usage
(starting from the production date given on the type field). This lifetime is based on the
endurance tests specified in standard EN 230/EN 298 and the table containing the rele-
vant test documentation as published by the European Association of Component
Manufacturers (Afecor) (www.afecor.org).
The designed lifetime is based on use of the burner controls according to the manufac-
turer’s Data Sheet and Basic Documentation.
After reaching the designed lifetime in terms of the number of burner startup cycles, or
the respective time of usage, the burner control is to be replaced by authorized person-
nel.
* The designed lifetime is not the warranty time specified in the Terms of Delivery
Disposal notes
The unit contains electrical and electronic components and must not be disposed of to-
gether with domestic waste.
Local and currently valid legislation must be observed.

Mechanical design
The following system components are integrated in the basic unit of the LMV5…:
•Burner control with gas valve proving system
•Electronic fuel / air ratio control for use with a maximum of 4 (LMV51…) or 6
(LMV52…) actuators
•Optional PID temperature / pressure controller (load controller)
•Optional variable speed drive module (VSD module)
Example:
Dual-fuel burner
- Gas: Modulating
- Oil: 2-stage
The system components (display and operating unit, actuators and O2 module) are in-
terconnected via a CAN bus system. Communication between the bus users is ensured
via a reliable, system-based data bus. For safety reasons, integration of the bus into
external CAN bus systems is not allowed. All safety-related digital inputs and outputs of
the system are constantly monitored by a contact feedback network (CFN). For flame
supervision in connection with the LMV5... and continuous operation, the QRI... infrared
flame detector, the QRA7... UV flame detector or an ionization probe can be used and,
for intermittent operation, the optical flame detectors type QRB... or QRA2…, QRA4.U,
QRA10… with AGQ1… (AC 230 V).
The burner management system is operated and programmed with the help of the dis-
play and operating unit (AZL5...) or a PC tool. The AZL5... features clear-text display
and menu-driven operation, thus offering straightforward operation and targeted diag-
nostics. To simplify diagnostics, the display shows the operating states, the type of fault
and the point in time the fault occurred. The different parameter setting levels for the
burner / boiler manufacturer and the heating engineer are protected by passwords. Ba-
sic settings that the plant operator can make on site do not demand a password. Fur-
ther, the display and operating unit serves as an interface to higher level systems such
as building automation and control systems (BACS) or a PC which has the ACS450
software installed. Among other features, the unit affords convenient readout of settings
and operating states, parameterization of the LMV5..., and trend logging.

Mechanical design (cont´d)
When replacing the LMV5... basic unit (BU), all parameters can be saved in a backup
memory of the AZL5… to be downloaded again when the new unit is installed. Hence,
manual reprogramming is not required.
To design specific fuel trains, the burner / boiler manufacturer can choose from a total
of 7 valve families and – by making use of the large number of parameter setting
choices (programming times, configuration of inputs and outputs, etc.) – fuel trains can
be matched to individual needs.
The SQM4.../SQM9... actuators are driven by stepper motors and offer high-resolution
positioning. The characteristics and settings of the actuators are defined by the LMV5...
basic unit.

Above a certain cable length, the actuators must be powered by a separate transformer
installed near the actuators.
The cross-sectional areas of the mains power lines (L, N, PE) and, if required, the
safety loop (safety limit thermostat, water shortage, etc.) must be sized for nominal cur-
rents according to the selected external primary fuse. The cross-sectional areas of the
other cables must be sized in accordance with the internal unit fuse (max. 6.3 AT).

can be ordered as accessory items. Other cables must not be used. If this is not
observed, the EMC characteristics of the LMV5... system will be unpredict-
able!
