1 Safety notes 08.12.20176
1 Safety notes
1.1 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
qualified staff
Before making any wiring changes in the connection area, 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 disconnected, there
is a risk of electric shock hazard
Ensure protection against electric shock hazard by providing adequate protection for
the connection terminals. If this is not observed, there is a risk of electric shock
Press the lockout reset button/operation button of the LME39... or the AGK20...
lockout reset button extension only manually (applying a force of no more than
10 N) without using any tools or pointed objects. If this is not observed, there is a
risk of loss of safety functions and a risk of electric shock
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. If this is not observed, there
is a risk of loss of safety functions and a risk of electric shock
Each time work has been carried out (mounting, installation, service work, etc.),
check to ensure that wiring and the parameterization are in an orderly state and
make the safety checks as described in Commissioning notes. If this is not
observed, there is a risk of loss of safety functions and a risk of electric shock
The data line for the AZL2… or other accessories, such as the OCI410 (plugs into
the BCI), must be connected or disconnected only when the burner control is dead
(all-polar disconnection), since the BCI does not ensure safe separation from mains
voltage. If this is not observed, there is a risk of electric shock
1.2 Engineering notes
When used in connection with actuators, there is no position feedback signal from
the actuator to the burner control
When used in connection with actuators, the requirements of applicable standards
and regulations must be observed
The running times of the actuators must match the burner control’s program. An
additional safety check of the burner 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)
1.3 Mounting notes
Ensure that the relevant national safety regulations are complied with

8/73
Building Technologies Division Basic Documentation LME39… CC1P7106en
1 Safety notes 03.02.2016
1.4 Installation notes
Always run the high voltage 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 and earthing, 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,
terminal 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 (50/60 Hz) or AC 230 V
(50/60 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 burner control must not
be connected
Check the connecting lines of the air pressure switch for short-circuits (air pressure
switch between terminals 2 and 6). If this is not observed, there is a risk of loss of
safety functions
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 is tapped after the gas
pressure switch and the safety limit thermostat to be connected to terminal 11 (refer
to Connection diagram)
For safety reasons, feed the neutral conductor to terminal 2. Connect the burner
components (fan, ignition transformer and fuel valves) to the neutral distributor as
shown below in the figure. The connection between neutral conductor and terminal 2
is prewired in the base
Example

N
Figure 1: Correct wiring of neutral conductors!
Note!
In extremely EMC-stressed environments, burners without fan motor or burners
equipped with fan control via auxiliary contactor should use an AGK25 to produce a
burden on terminal 3. If not observed, the burner is not reliably started up

1.5 Connection BCI via integrated jack RJ11
If the BCI (jack RJ11) is not used, protection against electric shock hazard must be
provided (jack must be covered up)
The AGV50... signal cable for the AZL2… or other accessories, for example BC
interface OCI410 (plugs into the jack RJ11), must be connected or disconnected
only when the burner control is dead (all-polar disconnection), since the BCI does
not ensure safe separation from mains voltage
The display and operating unit AZL2... is designed for direct connection to the
integrated jack RJ11 at LME39...
Since the BC interface has no safe separation from mains voltage, the signal cable
AGV50 must conform to certain specifications. Siemens has specified the signal
cable AGV50 for use under the burner hood; refer to Technical data. When using
other signal cables, it is not guaranteed that the required cable features will be
available.
Do not lay the signal cable AGV50... from the LME39… to the AZL2… together with
other cables (especially high-voltage ignition cable)
Service operation with a longer signal cable from LME39… to AZL2…, or from
LME39… to OCI410:
If a longer signal 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 signal cable can be subjected to increased mechanical stress. In
that case, extra cable sheathing is required (e.g. heat shrink tubing)
Both the signal cable AGV50... and the AZL2… 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
switching on power, the signal cable AGV50... is correctly connected to the AZL2…
The AZL2… must be used in a dry and clean environment
Connection display and operating unit AZL2...
Connect the AZL2... with the interface at your LME39..., follow the example design

1.6 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 and the ignition electrode are not protected against electric
shock hazard
Locate the ignition electrode and the ionization probe such that the ignition 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 Mbetween ionization probe and ground
– Soiled detector holders reduce the insulation resistance, thus supporting
creepage currents
Earth the burner in compliance with the relevant regulations; earthing the boiler
alone does not suffice

1.7 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
Delivery state (factory setting):
a) Burner startup with previously
interrupted line to the flame detector Lockout at the end of safety time Max. 3 repetitions
(can be parameterized)
b) Burner operation with simulated loss
of flame. For that purpose, cut off the
fuel supply
Lockout
Max. 3 repetitions
(can be parameterized)
c) Burner operation with simulated air
pressure failure (not with atmospheric
burners)
Immediate lockout
Table 1: Safety checks
After installation and commissioning, of a plant, 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 PC software ACS410, for example, or must
be written down. The documentation must be checked by the expert and then kept in a
safe place.
Warning!
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. If this is not observed, there is a risk of loss of safety
functions.
Prior to commissioning, the following points must be checked:
The correct time parameter settings, especially the settings of the safety and
prepurge 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. safety limit thermostat)
Minimum gas pressure (gas pressure switch)

4 Type summary (other types on request) 08.12.2017
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, 0.294 seconds or 4.851 seconds).
When parameterizing minimum or maximum times, the possibility of a ±7% tolerance must be taken into consideration.
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: Prepurge time shall be set to 30 seconds
Calculation: 30 seconds + 7% = 32.1 seconds
Value to be parameterized
(parameter 225): Must be equal to or greater than the calculated value (e.g. 32,34 seconds)
Example: Safety time shall be set via the change of postignition time to 5 seconds
Special case here: Safety time is set directly via the change of postignition time and flame detection time using the following formula:
TSA = t3n + tfz = P257 + 0.3 seconds + P228
Calculation: 5 seconds - 7% = 4.65 seconds
t3n = 4.65 seconds - 0.3 seconds - P228
t3n = 4.05 seconds (with tfz = 0.3 seconds)
Value to be parameterized
(parameter 257): Must be equal to or smaller than the calculated value (e.g. 3.969 seconds)
Legend tfz Flame detection time t4 Interval between ignition OFF and release fuel valve 2
TSA Safety time t8 Postpurge time
tw Waiting time t10 Specified time for air pressure signal
t1 Prepurge time t11 Programmed opening time for actuator
t1´ Purge time t12 Programmed closing time for actuator
t3 Preignition time t22 2nd safety time
t3n Postignition time (parameter 257 + 0.3 seconds)
1) Maximum running time available for actuator. The actuator’s running time must be shorter, otherwise, the actuator will not reach the required position
