Life cycle
The LMV5 burner control 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 is based on the continuous tests specified in standards EN 298.
A summary of the conditions has been published by the European Control
Manufacturers Association (Afecor - www.afecor.org).
The designed lifetime is based on use of the LMV5 according to the manufacturer’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 LMV5 is to be
replaced by authorized personnel.
* The designed lifetime is not the warranty time specified in the Terms of Delivery

Mechanical design
The following components are integrated in the LMV5:
Burner control with gas valve proving system
Electronic fuel-air ratio control for:
- A maximum of 4 actuators for LMV50 / LMV51
- A maximum of 6 actuators for LMV52
Optional PID temperature or pressure controller (boiler controller / load controller)
Optional VSD module
Example:
Dual-fuel burner
- Gas: Modulating
- Oil: 2-stage
The system components (AZL5, actuators, O2 module, etc.) are interconnected via a
bus system. Communication between the bus users takes place via a safety-related,
system-bound data bus (for safety reasons, integration of the bus into external CAN
bus systems is not possible). All safety-related digital outputs of the system are
permanently monitored via a contact feedback network. For flame supervision in
connection with the LMV5 and continuous operation, the infrared flame detector type
QRI / flame detector QRA7 or an ionization probe can be used, for intermittent
operation, optical flame detectors QRB / QRA2 / QRA4 / QRA10 with AGQ1 (AC 230
V).
The LMV5 is operated and programmed with the help of the AZL5 or a PC software.
The AZL5 with LCD clear text and menu-driven operation affords straightforward
operation and targeted diagnostics. For making diagnostics, 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 require a password. Also,
the AZL5 is used as an interface for superposed systems such as a building automation
and control system (BACS), or for a PC using the ACS450 software. Among other
features, the unit affords convenient readout of settings and operating states,
parameterization of the LMV5, and trend recording. When replacing the LMV5, all
parameters can be saved in a backup memory of the AZL5 to be loaded back into the
LMV5.
This means that reprogramming is not required.

Mechanical design (cont'd)
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 adaptions to
the specific application.
The universal SQM4 / SQM9 actuators are driven by stepper motors and can be
positioned with high resolution. The characteristics and settings of the actuators are
defined by the LMV5.

Note!
¹) If the cable length exceeds 50 m, additional loads must not be connected to the
status inputs (refer to «Power supply for the LMV5»)!
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
currents 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).
Min. cross-sectional area 0.75 mm²
(single- or multi-core to VDE 0100)
Cable insulation must meet the relevant temperature requirements and conform to the
environmental conditions. The CAN (bus) cables have been specified by Siemens and
can be ordered as accessory items. Other cables must not be used. If this is not
observed, the EMC characteristics of the LMV5 will be unpredictable!

Note!
The greater the detector cable capacitance (cable length), the lower the voltage at the
ionizations probe and, therefore, the lower the detector current. In the case of
extensive cable lengths and high-resistance flames, it may be necessary to use low-
capacitance cables (e.g. ignition cable). The electronic circuit is designed such that
impacts of the ignition spark on the ionization current will be largely eliminated.
Nevertheless, it must be ensured that the minimum detector current required will
already be reached during the ignition phase. If that is not the case, the connections of
the ignition transformer on the primary side must be changed and / or the location of
the electrodes also.
