3   For Your Safety
3 For Your Safety
Please observe the safety instructions to avoid personal injury and damage to property and 
the environment! 
The BT300 is a safety device! The device must not be opened, interfered with or modified. 
LAMTEC assumes no liability for damages arising as a result of unauthorised interference! 
• After commissioning and after each maintenance action check the exhaust gas values 
across the entire power range. 
• Qualified specialist staff are required to carry out all activities (assembly, installation, ser-
vicing, etc.).
• The burner or boiler manufacturer will ensure that the BT300 base unit is compliant with 
protection class IP40 or IP54 for outdoor use in accordance with DIN EN 60 529.
• Before working in the connection area, switch off the power supply to the plant from all 
poles. Ensure that it cannot be switched back on and that the plant is voltage-free. There 
is a risk of electric shock when the plant is not switched off.
• Place and secure the protection against contact on the BT300 and on all connected elec-
trical parts. The cover must fulfil the design, stability and protection requirements of 
EN 60730. 
• Plug connectors X30 - X34 have no protective separation from the mains voltage. To re-
place or disconnect the plug connectors, all poles of the plant must be disconnected from 
the mains.
• After each activity (e.g. assembly, installation, servicing, etc.) check the wiring and  
parameterisation to make sure it is in good working condition.
• If the equipment is dropped or suffers impact, you should no longer commission it. The 
safety functions may also be impaired but fail to show any obvious external damage.
• When the ratio curves are being programmed, the adjuster will continually monitor the 
quality of the plant's combustion (e.g. using an exhaust gas analysis station). In the event 
that the combustion values are inadequate or the conditions are potentially harmful, the 
adjuster will take suitable action, e.g. switch off the system manually.
• These operating instructions describe many possible applications and functions and 
should be used as guidelines. Carry out functional tests on the test bench and/or in the 
plant application to ensure correct functioning and document the results. 
Follow additional instructions to guarantee safety and reliability while operating the BT300:
• Condensation and humidity are to be avoided. If necessary, make sure that the installation 
is sufficiently dry before you switch it on.
• Avoid static charge having a destructive effect in case of touching the device's electronic 
components.
NOTICE!
LAMTEC recommends that you use ESD equipment while working on electrics/electronics.
3.1 Mounting Notes
• Please consider protection against contact when installing the BT300. Protection classes 
as IP 40 - IP 54 are minimum requirements for outdoor use in accordance with EN 60529 
and therefore obligatory.
• The protective cover of the BurnerTronic may only be opened by trained, qualified person-
nel.
• Make sure that settings for safety-relevant parameters are set in line with the requirements 
applicable to each type of combustion requiring monitoring and conform to the applicable 




8
3   For Your Safety
standards (by checking device parameters via operating elements or using remote-control 
software after commissioning). To verify settings you should also refer to manufacturer’s 
documentation of the combustion plant. Protecting the parameters in level 1 by setting a 
password will prevent any unauthorised change.
• Save setting values for the actuating elements across the power range of the burner as 
follows:
– Quantity of fuel
– Quantity of air
– All additional, safety-relevant actuating variables of the combustion
– While burner is modulating with at least five different firing-rate points
• Make sure that the combustion equipment operates stably and safely throughout the pow-
er range and in all combustion modes. For this purpose you should adjust the following 
values correctly:
– Actuating elements
– Parameter settings of the CO/O
2
 controller
– Combustion chamber pressure
– Fuel pressure
– Temperature
– Pressure of combustion air
– Heating value of fuel
• Ensure the connection between the actuators and control valves is form-fit throughout, 
gearing this towards the maximum controlling torques of the actuators.
• Only use external flame monitors compliant with DIN EN 298 or DIN EN 230 and author-
ised for continuous operation. Safety time of flame monitor must not extend 1 s.
• If the valve testing system is activated, connect the supply-side solenoid valve to terminal 
X01 and the burner-side solenoid valve to terminal X02. Connect the pressure monitor of 
the valve testing system to terminal X05. Adjust the gas pressure monitor and the dimen-
sions of the test section in order to make sure that the valve testing system is detecting a 
maximum leakage gas volume of 0.1 % in relation to the gas flow rate (minimum 50 dm³/
h) at maximum combustion heat output.
• Consider the potential danger depending on installation situation and position where the-
pressure equipment is being installed. Bear in mind the risk of external fire and the impact 
from traffic, wind and earthquake.
• When fixing duomodul plug-in connectors to insulation displacement technology (IDT) use 
HZ-M35 a modular crimping tool from Lumberg (see www.lumberg.com).
3.2 Security Advice - Mounting
• Compliance with national safety regulations and standards is obligatory at all times. 
• During the assembly and installation process, you must meet the requirements of stand-
ards DIN VDE  0100, 0550 and DIN VDE 0722
• To mount the BT300 basic unit, use screw fittings with an M4 thread (UNC32) or an M5 
thread (UNC24) and a maximum tightening torque of 1.8  Nm for fastening at all four fixing 
points. Keep in mind that housings have improved mechanical stability when connected 
on surrounding contact surfaces.  
Connect generally to an even mounting surface.

3.3 Installation Notes
• Lay high-voltage ignition cable always separately and in safe distance from device and 
other cables.
• Only trained, qualified personnel may open the BurnerTronic’s cover.
• Observe local and national regulations when wiring the electric cables inside the burner.
• Tighten the screw terminals of the BT300 using a tightening torque of > 0.5 Nm.
• Supply the feed cable with L, N and PE only. The N neutral conductor must not have po-
tential difference to the PE protective conductor.
• The pre-fuse for the BT300 should be max.10  A slow-blow.
• Phase, neutral and central point conductors must not be interchanged (this would lead to 
dangerous malfunctioning, loss of protection against contact, etc.).
• The strain relief for the connected cables must comply with standards (e.g. DIN EN 60730 
and DIN EN 60335).
• Make sure that no spliced strands can come into contact with any of the adjacent connec-
tions. Use appropriate end sleeves.
• The burner manufacturer is obligated to supply unused connections on the BT300 with 
dummy plugs.
• To replace or disconnect the plug connectors, all poles of the plant must be disconnected 
from the mains.
• Make a form-fit connection between the actuators and actuating elements for fuel and 
combustion air, as well as a form-fit connection for any additional actuator element.
• Optional components with safety extra low voltage (SELV) must be safely separated from 
the mains. Otherwise this can cause an electrical shock or damage the device due to a 
short-circuit.
• You may connect only passive devices or devices without feedback effects at the 230V 
outputs of the BT300 (like relays without additional voltage connection). In case of error it 
must be guaranteed that BT300 is not feeded with 230 V by this terminals. 
3.4 Electrical Connection Flame Sensor
Interruptions and losses in signal transmission need to be minimised: 
• Do not wire the sensor cable with other cables. 
Flame signal is reduced through line capacities.    Use a separate cable.
• Consider the permitted length of sensor cables.
• The ionisation flame sensor supplied from the mains is not protected against contact. Pro-
tection against accidental contact is therefore obligatory.
• Earth the burner according to instructions – earthing the boiler itself is not sufficient!
• Position ignition electrode and ionisation flame sensor where spark cannot hit ionisation 
flame sensor (risk of electrical overloading).

3   For Your Safety
3.5 Commissioning Notes
• Check all safety functions during commissioning!
• There is no feature to prevent RASTx connector plugs being transposed. Therefore en-
sure the correct assignment of the plant's plugs prior to commissioning.
• Check electromagnetic emissions specific to the application.
• While installing and commissioning the plant, the person in charge of the plant/heating 
technician needs to document the following: 
– Parameterised values
– Setting values (e.g. curve progressions)
– Values describing the fuel/air ratio control.
This data can be printed using LSB remote software or alternatively being kept as a hand-
written note.
Retain this documentation and have it checked by the "authority on the subject".
WARNING!
For BT300 parameterisations which deviate from the application standards can be carried out 
in access level 2. For this reason, check whether the parameterisation is consistent with the 
corresponding application standards (e.g. EN 298, EN 230, EN 676, EN 267, etc.) or the re-
spective plant has to be approved separately.
WARNING!
While unlocking the safety interlock chain in the mode "BURNER OFF" BT300does not lock 
the system. BT300 prevents a burner start-up until safety interlock chains are locked.
 In case your application needs an interlock of the plant  while unlocking the safety interlock 
chain also in "BURNER OFF" mode you must take suitable measures at the plant.
3.5.1 Fuel/Air Ratio Control
• Guarantee proper operation by ensuring adequate excess air.  
In order to do this, set values for fuel and combustion air in such as
– combustion chamber pressure
– fuel pressure
– temperature and the pressure of the combustion air
to ensure proper operation through the entire range of burner firing-rate until next periodic 
inspection.
• Pay attention to wear and tear of actuators and actuator elements.
• Measure characteristic values of combustion process to document proper operation.




11
3   For Your Safety
3.5.2 Basic Device
Check the following items prior to commissioning: 
• Valves must be assigned correctly to valve outputs on BT300.
• Correct setting of time parameters (especially safety and pre-ventilation times).
• Flame sensor functioning well in case of flame blow-off during operation (incl. flame-out 
response time) or when parasitic light is present during pre-ventilation period and also at 
a missing flame formation while end of safety period starts.
• Activated leakage control function of gas valves and correct leakage measurement, when 
required by an application.
3.6 Tasks fulfilled by "authority on the subject" during Approval Test 
By specifying the assigned DIN registration number and product ID number the manufacturer 
confirms that model BT300 burner control system is consistent with type-tested system.
The connection between actuators and actuator elements for fuel and combustion air and also 
to any additional actuator elements used must be form-fit.
3.6.1 Checking for Correct Parameterisation in System
While installating and commissioning the plant the person in charge of the plant/heating tech-
nician needs to document the following: 
• Parameterised values
• Setting values (e.g. curve progressions)
• Values describing fuel/air ratio control.
This data can be printed using LSB remote software or alternatively being kept as a handwrit-
ten note.
Retain this documentation and have it checked by the "authority on the subject".
NOTICE!
For BT300 parameterisations which deviate from application standards can be carried out in 
access level 2. For this reason, check whether the parameterisation is consistent with the cor-
responding application standards (e.g. EN 298, EN 230, EN 676, EN 267, etc.) or the respec-
tive plant has to be approved separately.
3.6.2 Checking the Fuel/Air Ratio Control System
Save setting values (curve parameters) for actuator elements, fuel and combustion air through 
the complete range of burner firing-rate in sufficient number. 
Select setting values of fuel and combustion air considering combustion chamber pressure, 
fuel pressure, temperature and pressure of the combustion air in order to guarantee proper 
operation with adequate excess air through the entire range of burner firing-rate. 
The burner/boiler manufacturer has to document this by measuring reference values of the 
combustion process.




12
3   For Your Safety
3.6.3 Checking Burner Sequencer Part
Check the following:
• Correct setting of time parameters (especially safety and pre-ventilation periods).
• Whether an ionisation flame sensor or a corresponding flame scanner is used since only 
these are capable of running in continuous operation. 
• Functioning of flame sensor in case of flame blow-off during operation, parasitic light being 
present during pre-ventilation period and missing flame formation at the end of the safety-
period. 
• Check the performance of all available and/or essential incomming signals, such as for: 
– Air pressure
– Gas pressure - min/oil pressure - min
– Safety interlock chain (e.g. STB)
• Activated Leakage control function for gas valves if required for application purposes. 
– If necessary, ensure a correct leakage quantification.

4   Functional Description
4 Functional Description
BT300 combines the benefits of an electronic fuel/air ratio control system with up to three mo-
torised actuator elements and optional modules like an analogue output for speed control of 
the combustion air fan with an electronic burner control unit. The leakage test, flame monitor-
ing system, power control unit and (optional) CO/O
2
 controller for control and optimisation of 
an oil or gas-fired forced-draught burner are all integrated.
BT300 is suitable for virtually all combustion plants. Safety interlock chains, monitors (e.g. gas 
and air pressure) and sensors are wired directly to the BT300. This greatly reduces the cost 
of additional relays and wiring. The BT300 is designed to be attached to the burner. The short 
wiring paths also save money. As a result, BT300 is particularly suitable as standard equip-
ment for monoblock burners.
The compact design of BT300 burner control system also has its advantages during commis-
sioning. Standardisation of wiring and operator interface minimises sources of errors right 
from the start. Moreover, intelligent display information is making search for errors much eas-
ier.
The BT300 is available in five designs:
Burner sequencer and fuel/air ratio control can be adjusted for a wide range of combustion 
conditions by setting parameters. The BT300 for oil and gas can be set to start with and with-
out pilot burner. The integrated leakage test can be run before ignition or after shutting down 
the burner.
Starting without pre-ventilation using gas is available in accordance with EN676.
The setting of fuel/air ratio curves can be optimised using optional CO/O
2
 control during op-
eration. This helps to counteract conditions that interfere with combustion. This ensures a per-
manent burner operation at the greatest possible efficiency.
Operating and fault messages are displayed by symbols and numbers on UI300 User Inter-
face. Plant-specific configurations and settings of fuel/air ratio control curves are operated via 
menu of UI300 User Interface.
An operating and start-up counter is integrated.
The optional LCM100 power control unit with two setpoints, external setpoint shift (control by 
atmospheric condition) and start-up control is also available.
• BT320 2 motorised control outputs 
1 continuous output 0 ... 10 V, 0/4 ... 20 mA for speed control of the  
   combustion air fan using VSM100 (optional)

6   Leakage Test for Main Gas Valves
6.2 Leakage Test with Ventilation Via Roof 
The leakage test checks whether or not the main gas valves are leakproof. For this purpose 
the gas pressure of the supply is analysed.
As leakage test section (space between the two main valves) burns empty whenever the burn-
er is switched off, this part is usually pressureless at start-up (gas pressure > min = 0). This is 
checked by BurnerTronic. At this point, main gas 1 opens briefly and gas flows into test section 
(gas pressure > min switches from 0 to 1). This pressure must remain constantly at least while 
leakage test period (P 311) is running. The leakage test is considered complete then. 
If leakage test section is not empty at start-up (e.g. resulting from a previous fault shutdown), 
main gas valve 2 opens first. The leakage test line is then ventilated (depending on the plant, 
either in the combustion chamber or through the roof – for wiring proposition, see chapter  6.3 
Exhaust of Test Line Over the Roof). During leakage test period section is checked whether 
it remains pressureless or not. Apart from that the process is the same as described above. 
The leakage test takes place prior to ignition.
You must connect the pressure monitor for the leakage test line at the “Gas pressure > min” 
input on plug X05. It also monitors the minimum pressure during operation. If a different min-
imum pressure should be monitored during operation, the pressure monitor must be inserted 
into the safety interlock chain gas or into the controller loop (burner ON). You must assure by 
dimensioning the gas line in a way that leakage test control time is sufficient for detecting re-
liably a burner gas consumption leakage of 0.1%, but at least 50 dm
3
/h (at maximum combus-
tion heat output).
NOTICE!
You may only vent 0.05 % of fuel consumption at maximum firing-rate into combustion cham-
ber.

NOTICE!
Consider diameter of gas line in the roof ventilation. For ventilation, plug X02 is activated for 
3 s. Make sure that this period is sufficient even for smallest ventilation line diameter!
