Warning notes
To avoid injury to persons, damage to property or the environment, the following
warning notes must be observed!
Do not to open, interfere with or modify the unit!
•All activities (mounting, installation and service work, etc.) must be performed by quali-
fied staff
•Before making any wiring changes in the connection area of the LME39…, completely
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 discon-
nected, there is a risk of electric shock hazard
•Ensure protection against electric shock hazard by providing adequate protection for
the burner control’s connection terminals
•Check the connecting lines of the air pressure switch for short-circuits («LP» between
terminals 2 and 6)
•Press the lockout reset button / operation button only manually (applying a force of no
more than 10 N) without using any tools or pointed objects
•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
•Each time work has been carried out (mounting, installation, service work, etc.), check
to ensure that wiring is in an orderly state and make the safety checks as described in
«Commissioning notes»
•The data line for the AZL2… display and operating unit or other accessories, such as
the OCI410… (plugs into the BCI interface), must be connected or disconnected only
when the burner control is dead (all-polar disconnection), since the BCI interface does
not ensure safe separation from mains voltage
Engineering notes
•When used in connection with actuators, there is no position feedback signal from the
actuator to the burner control
•The running times of the actuators must match the burner control’s program. An addi-
tional safety check of the burner control together with the actuators is required
•If the communication interface (jack RJ11) is not used, protection against electric
shock hazard must be provided (jack must be covered up)
Mounting notes Ensure that the relevant national safety regulations are complied with.

Parameterization Siemens supplies the LME39… burner controls with the factory settings as specified in
«Type summary».
The OEM can change the Siemens default settings to meet its own requirements.
With the LME39…, the burner control’s characteristics are determined primarily through
parameterization. Every time the unit is recommissioned, the parameter settings must be
checked. The LME39… must never be transferred from one plant to another without
matching the parameters to the new plant.
Caution Parameters and settings may only be changed by qualified staff.
If parameters are changed, responsibility for the new parameter settings is assumed by
the person who – in accordance with the access rights – has made parameter changes
on the respective access level.
After parameterization, the OEM must check to ensure that safe burner operation will
be warranted.
The OEM which made the settings is always responsible for the parameters, their set-
tings and compliance of the respective application with the relevant national and inter-
national standards and safety regulations, such as EN 676, EN 267, EN 1643, etc.
Siemens, its suppliers and other Group Companies of Siemens Ltd. do not assume
responsibility for special or indirect damage, consequential damage, other damage, or
damage resulting from wrong parameterization.
Warning If the factory settings are changed, all changes made must be documented and
checked by the OEM.
The OEM is obliged to mark the unit accordingly and to include at least the list of device
parameters and settings in the burner’s documentation.
Siemens also recommends attaching an additional mark on the LME39… in the form of
an adhesive label. As specified in EN 298, the label should be easy to read and wipe
proof.
The label with a maximum size of 70 x 45 mm can be attached to the upper part of the
housing.

Installation notes
•Always run the ignition cables separate from the unit and other cables while observing
the greatest possible distance
•Do not mix up live and neutral conductors
•Install switches, fuses, earthing, etc., in compliance with local regulations
•The connection diagrams show the burner controls with earthed neutral conductor.
In networks with nonearthed neutral conductor and ionization current supervision, ter-
minal 2 must be connected to the earth conductor via an RC unit (product no.
ARC 4 668 9066 0). It must be made certain that local regulations are complied with
(e.g. protection against electric shock hazard) since AC 120 V / 50 Hz or
AC 230 V / 60 Hz mains voltage produces peak leakage currents of 2.7 mA
•Make certain that the maximum permissible current rating of the connection terminals
will not be exceeded
•Do not feed external mains voltage to the control outputs of the unit. When testing the
devices controlled by the burner control (fuel valves, etc.), the LME39… must not be
connected
•In the case of burners with no fan motor, an AGK25 must be connected to terminal 3
of the unit, or else the burner cannot reliably be started up
•To prevent mixup of different types of burner controls, the LME39… must always be
used in connection with grey plug-in bases AGK11.6. Make absolutely certain that the
live conductor for the control thermostat or pressurestat «R / W» is tapped after the
gas pressure switch «GP» and the safety limit thermostat «STB» and connected to
terminal 11 (refer to «Connection diagram»)
•Connecting cable from LME39… to AZL2…or from LME39… to OCI400 / OCI410…:
Since the BCI interface has no safe separation from mains voltage, the connecting ca-
ble between LME39… and AZL2…, or LME39… and OCI400 / OCI410…, must con-
form to certain specifications. Siemens has specified the cable for use under the
burner hood (cable supplied by Hütter; refer to «Technical data»). When using cables
of other manufacture, Siemens’ requirement will not necessarily be met
•Do not lay the connecting cable from the LME39… to the AZL2… together with other
cables. Use a separate cable
•Service operation with a longer connecting cable from LME39… to AZL2…, or from
LME39… to OCI410…:
If a longer cable is required for service work for example (short-time, <24 hours), note
that above usage under the burner hood no longer applies and, for this reason, the
cable can be subjected to increased mechanical stress. In that case, extra cable
sheathing is required (e.g. heat shrink tubing)
•Both the cable and the AZL2… display and operating unit must be shipped and stored so
that no damage due to dust and water can occur when used in the plant later on
•To ensure protection against electric shock hazard, make certain that, prior to switch-
ing on power, the cable is correctly connected to the AZL2…
•The AZL2… must be used in a dry and clean environment
•For safety reasons, feed the neutral conductor to terminal 2. Connect the burner com-
ponents (fan, ignition transformer and gas valves) to the neutral distributor as shown
below in the illustration. The connection between neutral conductor and terminal 2 is
prewired in the base

Electrical connection of flame detectors
It is important to achieve practically disturbance- and loss-free signal transmission:
•Never run detector cables together with other cables
– Line capacitance reduces the magnitude of the flame signal
– Use a separate cable
•Observe the permissible length of the detector cables (refer to «Technical data»)
•The ionization probe is not protected against electric shock hazard
•Locate the high-voltage ignition electrode and the ionization probe such that the igni-
tion spark cannot arc over to the ionization probe (risk of electrical overloads) and that
it cannot adversely affect the supervision of ionization
•Insulation resistance
– Must be a minimum of 50 MΩbetween ionization probe and ground
– Soiled detector holders reduce the insulation resistance, thus supporting cree-
page currents
•Earth the burner in compliance with the relevant regulations; earthing the boiler alone
does not suffice
Commissioning notes When commissioning the plant for the first time or when doing maintenance work, make
the following safety checks:
Safety check to be carried
out Expected response
Supply state (factory setting):
a) Burner startup with previously
interrupted line to the flame
detector
Lockout at the end of «TSA»
→Max. 3 repetitions
b) Burner operation with simulated
loss of flame. For that purpose,
cut off the gas supply
•Establishment of flame at the end of
«TSA»
→Max. 3 repetitions
(can be parameterized)
→Factory setting: Lockout
•No establishment of flame at the end
of «TSA»
→Lockout
c) Burner operation with simulated
air pressure failure (not with
atmospheric burners)
Immediate lockout
After installation and commissioning, the parameterized values and settings must be
documented by the person / heating engineer responsible for the plant. These data can
be printed out with the help of the ACS410 PC software, for example, or must be written
down. The documentation must be checked by the expert and then kept in a safe place.
On the OEM access level of the LME39…, it is possible to make parameter settings
that differ from application standards. When setting the parameters, it must be made
certain that the application will run safely in accordance with legal requirements.
Prior to commissioning, the following points must be checked:
•The correct time parameter settings, especially the settings of the safety and pre-
purge times
•The correct functioning of the flame detector in the event of loss of flame during
operation (including the response time); with extraneous light, during the prepurge
time and, when there is no establishment of flame, at the end of the safety time
•Air pressure
•Safety loop (e.g. STB)
•Minimum gas pressure (GP)

Note on parameterization:
Use the AZL2… or ACS410 to always set the exact value of the required time (multiples of increments of 0.147
seconds or 0.294 seconds).
When parameterizing minimum or maximum times, the possibility of a ±7% tolerance must be taken into con-
sideration.
For minimum values: The value to be parameterized must be at least 7% greater.
For maximum values: The value to be parameterized must be at least 7% smaller.
Example: t1min shall be set to 30 s
Calculation: 30 s + 7% = 32.1 s
Value to be parameterized: Must be equal to or greater than the calculated value
(e.g. 32.34 s)
Example: TSAmax. shall be set to 5 s
Special case here: TSA is set directly via the change of t3n using the following formula:
t3n = TSA – 0.7 s
Calculation: 5 s – 7% = 4.65 s
t3n = 4.65 s – 0.7 s = 3.95 s
Value t3n to be
parameterized: Must be equal to or smaller than the calculated value (e.g. 3.822 s)

Technical data (cont´d)
LME… burner controls have 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 298 and the table containing the relevant 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 personnel.

Flame supervision with ionization probe is accomplished by making use of the conductivity
and rectifying effect of the flame. The flame signal amplifier only responds to the DC cur-
rent component of the flame signal. A short-circuit between ionization probe and ground
causes the burner to initiate lockout.

When lockout occurs, the burner control can immediately be reset. To do this, press the
lockout reset button for about 1 second (<3 seconds). The LME39… can only be reset when
all contacts in the line are closed and when there is no undervoltage.
If no flame is established at the end of «TSA», or if the flame is lost during operation, a
maximum of 3 repetitions per controlled startup can be performed via «R», or else lockout
will be initiated. Counting of repetitions is restarted each time a controlled startup via «R»
takes place.
Duty of PC tool software:
The PC tool is a component of the LME39… system and serves primarily as an operator
module for the following basic tasks:
•Visualization of system status with the following data:
- Parameters
- Process data
•Configuration and parameterization of the basic unit (individual parameters)
•Reset

The multicolor signal lamp (LED) in the lockout reset button is the key
indicating element for visual diagnostics and interface diagnostics.
Both «EK...» and LED are located under the transparent cover of the lockout reset button.
There are 3 diagnostics choices:
1. Visual diagnostics: Operational status indication or diagnostics of the cause of fault
2. Interface diagnostics: With the help of the OCI400 / OCI410 interface adapter and the
ACS410 PC software or flue gas analyzers of different makes
3. On the display of the AZL2…
Visual diagnostics:
In normal operation, the different operating states are indicated in the form of color codes
according to the color code table given below.
During startup, status indication takes place according to the following table:

Operation, indication, diagnostics (cont´d)
After lockout, the red fault signal lamp is steady on. In that condition, visual diagnostics of
the cause of fault according to the error code table can be activated by pressing the lock-
out reset button for at least 3 seconds. Pressing the reset button again for at least 3 sec-
onds activates interface diagnostics. If, by accident, interface diagnostics has been acti-
vated, in which case the slightly red light of the signal lamp flickers, it can be deactivated
by pressing again the lockout reset button for at least 3 seconds. The instant of switching
over is indicated by a yellow light pulse.
The following sequence activates the diagnostics of the cause of fault:

During the time the cause of fault is diagnosed, the control outputs are dead.
- Burner remains shut down
- External fault indication remains deactivated
- Fault status signal «AL» at terminal 10, according to the error code table
The diagnostics of the cause of fault is quit and the burner switched on again by resetting
the burner control. Press the lockout reset button for about 1 second (<3 seconds).
