Gas operation: From the supply line the gas fuel passes through the gas train (filter, safety valves, gas pressure regulator and butterfly valve). The pressure
regulator sets the gas pressure within the combustion head utilization limits. Air is supplied by a fan, which may be onboard or separated depending on burner
configuration, and is channeled through an air damper.
The air damper and the gas butterfly valve are actuated by servomotors according to load curves, in order to achieve the correct proportion between fuel and air
flows, and to optimize flue gas parameters.
The adjustable combustion head can improve the burner performance by controlling the flame geometry and combustion efficiency.
Fuel and air are routed through separated channels inside the combustion head, then mixed to ignite the flame inside the combustion chamber. The ignition spark is
provided by electrodes and a high voltage transformer (a pilot flame may also be employed, depending on burner configuration).
Pre-ventilation of the combustion chamber is usually implemented according to gas directives.
The control panel, onboard or separated, allows the operator to monitor each operating phase.

To check if the burner is suitable for the boiler to which it must be installled, the following parameters are needed:
 furnace input, in kW or kcal/h (kW = kcal/h/860);
 backpressure (data are available on the boiler ID plate or in the
user’s manual).
Example:
Furnace input: 600kW
Backpressure: 4 mbar
In the “Performance curve” diagram, draw a vertical line matching the
furnace input value and an horizontal line matching the backpressure
value. The burner is suitable if the intersection point A is inside the performance curve.
Data are referred to standard conditions: atmospheric pressure at 1013
mbar, ambient temperature at 15° C.

To check the proper gas train size, it is necessary to the available
gas pressure value upstream the burner’s gas valve. Then subtract
the backpressure. The result is called pgas. Draw a vertical line
matching the furnace input value (600kW, in the example), quoted
on the x-axis, as far as intercepitng the network pressure curve,
according to the installed gas train (DN65, in the example). From the
interception point, draw an horizontal line as far as matching, on the
y-axis, the value of pressure necessary to get the requested furnace
input. This value must be lower or equal to the pgas value, calculated before.

NOTE: The performance curve is a diagram that represents the burner performance in the type approval phase or in the laboratory tests, but does not represent the
regulation range of the machine. On this diagram the maximum output point is usually reached by adjsuting the combustion head to its “MAX” position (see paragraph
“Adjusting the combustion head”); the minimum output point is reached setting the combustion head to its “MIN” position. During the first ignition, the combustion head is set
in order to find a compromise between the burner output and the generator specifications, that is why the minimum output may be different from the Performance curve

Combustion head gas pressure curves
Combustion head gas pressure depends on gas flow and combustion chamber backpressure. When backpressure is subtracted, i
depends only on gas flow, provided combustion is properly adjusted, flue gases residual O2 percentage complies with “Recommended
combustion values” table and CO in the standard limits). During this stage, the combustion head, the gas butterfly valve and the
actuator are at the maximum opening. Refer to , showing the correct way to measure the gas pressure, considering the values o
pressure in combustion chamber, surveyed by means of the pressure gauge or taken from the boiler’s Technical specifications.

Measuring gas pressure in the combustion head
In order to measure the pressure in the combustion head, insert the pressure gauge probes: one into the combustion chamber’s pressure outlet to get the pressure in the combustion chamber and the other one into the butterfly valve’s pressure outlet of the burner. On
the basis of the measured differential pressure, it is possible to get the maximum flow rate: in the pressure - rate curves (showed on the
next paragraph), it is easy to find out the burner’s output in Stm3/h (quoted on the x axis) from the pressure measured in the combustion
head (quoted on the y axis). The data obtained must be considered when adjusting the gas flow rate.

Matching the burner to the boiler (low NOx burners)
The burners described in this manual have been tested with combustion chambers that comply with EN676 regulation and whose
dimensions are described in the diagram . In case the burner must be coupled with boilers with a combustion chamber smaller in diameter or shorter than those described in the diagram, please contact the supplier, to verify that a correct matching is possible, with
respect of the application involved. To correctly match the burner to the boiler verify the type of the blast tube . Verify the necessary
input and the pressure in combustion chamber are included in the burner performance curve; otherwise the choice of the burner must
be revised consulting the burner manufacturer. To choose the blast tube lenght consider the following rule, even if it differs from the
instructions of the boiler manufacturer: Cast-iron boilers, three pass flue boilers (with the first pass in the rear part): the blast tube must
protrude at least 150÷200 mm into the combustion chamber.The length of the blast tubes does not always allow this requirement to be
met, and thus it may be necessary to use a suitably-sized spacer to move the burner backwards.

LIMITATIONS OF USE
THE BURNER IS AN APPLIANCE DESIGNED AND CONSTRUCTED TO OPERATE ONLY AFTER BEING CORRECTLY CONNECTED TO A HEAT GENERATOR (E.G. BOILER, HOT AIR GENERATOR, FURNACE, ETC.), ANY OTHER USE IS TO BE CONSIDERED IMPROPER AND THEREFORE DANGEROUS.
THE USER MUST GUARANTEE THE CORRECT FITTING OF THE APPLIANCE, ENTRUSTING THE INSTALLATION OF IT TO
QUALIFIED PERSONNEL AND HAVING THE FIRST COMMISSIONING OF IT CARRIED OUT BY A SERVICE CENTRE AUTHORISED BY THE COMPANY MANUFACTURING THE BURNER.
A FUNDAMENTAL FACTOR IN THIS RESPECT IS THE ELECTRICAL CONNECTION TO THE GENERATOR’S CONTROL AND
SAFETY UNITS (CONTROL THERMOSTAT, SAFETY, ETC.) WHICH GUARANTEES CORRECT AND SAFE FUNCTIONING OF
THE BURNER.
THEREFORE, ANY OPERATION OF THE APPLIANCE MUST BE PREVENTED WHICH DEPARTS FROM THE INSTALLATION
OPERATIONS OR WHICH HAPPENS AFTER TOTAL OR PARTIAL TAMPERING WITH THESE (E.G. DISCONNECTION, EVEN
PARTIAL, OF THE ELECTRICAL LEADS, OPENING THE GENERATOR DOOR, DISMANTLING OF PART OF THE BURNER).
NEVER OPEN OR DISMANTLE ANY COMPONENT OF THE MACHINE EXCEPT FOR ITS MAINTENANCE.
TO SECURE THE MACHINE, ACT ON THE ISOLATOR SWITCH. IN CASE OF ANOMALIES THAT REQUIRED A SHUT DOWN OF
THE BURNER, IT’S POSSIBLE TO ACT ON THE AUXILIARY LINE SWITCH, LOCATED ON THE BURNER FRONT PANEL.
IN CASE OF A BURNER SHUT-DOWN, RESET THE CONTROL BOX BY MEANS OF THE RESET PUSHBUTTON. IF A SECOND
SHUT-DOWN TAKES PLACE, CALL THE TECHNICAL SERVICE, WITHOUT TRYING TO RESET FURTHER.
WARNING: DURING NORMAL OPERATION THE PARTS OF THE BURNER NEAREST TO THE GENERATOR (COUPLING
FLANGE) CAN BECOME VERY HOT, AVOID TOUCHING THEM SO AS NOT TO GET BURNT.

Burners fitted with gas proving system: the gas proving system test begins; when the test is performed the proving system LED
turns on. At the end of the test, the burner staring cycle begins: in case of leakage in a valve, the gas proving system stops the burner and the lamp B1 turns on.
At the beginning of the start-up cycle, the actuator drives the air damper to the maximum opening position, then the fan motor
starts up: the pre-purge phase begins. During the pre-purge phase, the air damper complete opening is signalled by the light B2 on
(see front panel).
At the end of the pre-purge, the air damper is driven to the ignition position, the ignition transformer is energised (signalled by the
light B4 on the front panel) then, few seconds later, the EV1 and EV2 gas valves are energised (light G1 and G2 on the front
panel).
Few seconds after the gas valves opening, the ignition transformer is de-energised and light B4 turns to off.
The burner operates in the low flame stage; few seconds later the two-stages operation begins and the burner output increases or
decreases, driven by the external thermostats (progressive burners) or by the modulator (fully-modulating burners).
.
Double selector operationTo regulate the burner, use the 2 selectors SMA and SMF on the burner control panel, instead of
using the thermostat TAB.The position of the selectors determines the operation:to switch the burner to high flame, set the SMA
switch to MAN. and the SMF switch to MAX;to bring it to low flame set SMF to MIN.By setting the SMA switch to AUTO, the SMF switch
is deactivated and the burner is controlled in high/low flame by the thermostat TAB.

PART III: OPERATION
Integrated proving system (burners equipped with LME7x, LMV, LDU)
This paragraph describes the integrated proving system operation sequence:
 At the beginning both the valves (EV1 and EV2) must be closed.
 Test space evacuating: EV2 valve (burner side) opens and keep this position for a preset time
(td4), in order the bring the test space to ambient pressure.Test atmospheric pressure: EV2 closes
and keep this position for a preset time (test time td1). The pressure switch PGCP has not to detect
a rise of pressure.
 Test space filling: EV1 opens and keep this position for a preset time (td3), in order to fill the test
space.
 Test gas pressure: EV1 closes and keep this position for a preset time (td2). The pressure switch
PGCP has not to detect a pressure drop down.
If all of the test phases are passed the proving system test is successful, if not a burner lockout
happens.
On LMV5x and LMV2x/3x and LME73 (except LME73.831BC), the valve proving can be
parameterized to take place on startup, shutdown, or both.
On LME73.831BC the valve proving is parameterized to take place on startup only.

ADJUSTING AIR AND GAS FLOW RATES
WARNING! During commissioning operations, do not let the burner operate with insufficient air flow (danger of
formation of carbon monoxide); if this should happen, make the fuel decrease slowly until the normal combustion
values are achieved.
WARNING! the combustion air excess must be adjusted according to the values in the following chart.
Recommended combustion parameters

Adjustments - brief description





The air and fuel rates adjustments must be performed at the maximum ouptput first (“high flame”): see the LMV related manual.
Check that the combustion parameters are in the suggested limits.
Check the flow rate measuring it on the counter or, if it was not possible, verifying the combustion head pressure by means of a differential pressure gauge, as described on par. “Measuring the gas pressure in the combustion head”.
Then, adjust the combustion values by setting the “gas/air” ratio” curvepoints (see the LMV related manual).
Set, now, the low flame output (according to the procedure described on the “Siemens LMV manual”) in order to avoid the low
flame output increasing too much or that the flues temperature gets too low to cause condensation in the chimney.
(First) Start-up preliminary operations - gas supply
Recommended actions to be carried out in sequence:
1 Check the burner and all its components are installed correctly
2 Check that all electrical and mechanical parts are connected correctly
3 Check that there is water or other vector fluids in the generator
4 Check that the ventilation gates/dampers in the plant are open and the stack is free
5 Connect the gauges used to adjust and check pressures on the incoming line and on the head, air and fuel side.
6 Open the thermostatic series and the safety chain
7 Turn the main switch on the panel front with the "ON/OFF" selector to position "ON".
8 Check the phase and neutral position is correct
9 Open the manual shut-off valves slowly, in order to prevent any water hammers that might seriously damage valves and pressure
regulator
10 Check the sense of rotation of the electrical motors
11 Bleed the line, getting rid of all the air in the pipe as far as the main gas valve
26
PART III: OPERATION
12 Ensure the pressure entering the main valves is not excessive due to damage to or wrong adjustment of the line pressure regulator
13 Ensure the gas supply minimum pressure is at least equal to the pressure required by the pressure curves - burnt gas flow
DANGER! Venting the air from the piping must take place in safe conditions, avoiding dangerous concentrations
of fuel in the rooms. You must therefore ventilate the rooms and wait long enough for the gases to dissipate outside before switching on.
To ensure the proper operation of the flow sensors, the fuel/air pipes must be free of liquid residues such as oil
or water. Also, make sure that the silencer is installed on the air intake.

Adjusting the gas valves group
Multibloc MB-DLE
C
VS
The multibloc unit is a compact unit consisting of two valves, gas pressure switch, pressure stabilizer and gas filter.
The valve is adjusted by means of the RP regulator after slackening the locking screw VB
by a number of turns. By unscrewing the regulator RP the valve opens, screwing the valve
closes. To set the fast opening remove cover T, reverse it upside down and use it as a tool
to rotate screw VR. Clockwise rotation reduces start flow rate, anticlockwise rotation increases it.
Do not use a screwdriver on the screw VR!
The pressure stabilizer is adjusted by operating the screw VS located under the cover C.
By screwing down the pressure is increased and by unscrewing it is reduced.
Note: the screw VSB must be removed only in case of replacemente of the coil.

PART III: OPERATION
Calibration air and gas pressure switches
The air pressure switch locks the control box if the air pressure is not the one requested. If it
happens, unlock the burner by means of the control box unlock pushbutton, placed on the burner control panel.
The gas pressure switches check the pressure to avoid the burner operate when the pressure value is not in the requested pressure range.
VR
Calibration the maximum gas pressure switch (when provided)
To calibrate the maximum pressure switch, proceed as follows according to its mounting position:
 remove the pressure switch plastic cover;
 if the maximum pressure switch is mounted upstreaam the gas valves: measure the gas pressure in the network, when flame is off;
by means of the adjusting ring nut VR, set the value read, increased by the 30%.
 if the maximum pressure switch is mounted downstream the “gas governor-gas valves” group and upstream the butterfly valve:
light the burner, adjust it according to the procedure in the previous paragrph. Then, measure the gas pressure at the operating
flow rate, downstream the “gas governor-gas valves” group and upstream the butterfly valve; by means of the adjusting ring nut
VR, set the value read on step 2, increased by the 30%;
 replace the plastic cover.
Calibration of air pressure switch
To calibrate the air pressure switch, proceed as follows:
 Remove the transparent plastic cap.
 Once air and fuel setting have been accomplished, startup the burner.
 During the pre-purge phase o the operation, turn slowly the adjusting ring nut VR in the clockwise direction (to increase the adjusting pressure) until the burner lockout, then read the value on the pressure switch scale and set it to a value reduced by 15%.
 Repeat the ignition cycle of the burner and check it runs properly.
 Refit the transparent plastic cover on the pressure switch.
Calibration of low gas pressure switch
With the burner operating at maximum power, increase the regulation pressure by slowly turning the control knob clockwise until the
burner stops, taking care it does not go into lockout and the display shows the error "Err c20 d0".
As for the gas pressure switch calibration, proceed as follows:
 Be sure that the filter is clean.
 Remove the transparent plastic cap.
 While the burner is operating at the maximum output, test the gas pressure on the pressure port of the minimum gas pressure
switch.
 Slowly close the manual cutoff valve (placed upstream the pressure switch, see gas train installation diagram), until the detected
pressure is reduced by 50%. Pay attention that the CO value in the flue gas does not increase: if the CO values are higher than the
limits laid down by law, slowly open the cutoff valve as to get values lower than these limits.
 Check that the burner is operating correctly.
 Clockwise turn the pressure switch adjusting ring nut (as to increase the pressure value) until the burner stops.
 Slowly fully open the manual cutoff valve.
 Refit the transparent plastic cover on the pressure switch.
Calibration the maximum gas pressure switch (when provided)
To calibrate the maximum pressure switch, proceed as follows according to its mounting position:
 remove the pressure switch plastic cover;
 if the maximum pressure switch is mounted upstreaam the gas valves: measure the gas pressure in the network, when flame is off;
by means of the adjusting ring nut VR, set the value read, increased by the 30%.
 if the maximum pressure switch is mounted downstream the “gas governor-gas valves” group and upstream the butterfly valve:
light the burner, adjust it according to the procedure in the previous paragrph. Then, measure the gas pressure at the operating
flow rate, downstream the “gas governor-gas valves” group and upstream the butterfly valve; by means of the adjusting ring nut
VR, set the value read on step 2, increased by the 30%;
 replace the plastic cover.
Calibration gas leakage pressure switch (PGCP)

Check that the gas meter is not moving when the burner is off. In case it is rotating, look for possible leaks.
Check the cleaning condition of the vent. Clean the vent by using exclusively a dry brush. If needed, disassemble it from the
motor’s shaft and wash it by using non corrosive detergents. Prior to disassemble the vent, take the measurements in relation to
the motor's shaft, so as to reassemble it in the same position.
Check that all parts in contact with combustive air (air box, protection mesh and Archimedean screw) are clean and free from any
obstruction that might impede free afflux. Clean it with compressed air if available and/or a dry brush or cloths. Eventually wash it
with non corrosive detergents.
Check the blast tube; it must be substituted in case of obvious cracks or anomalous holes. Slight deformations that do not affect
combustion may be tolerated
Check the condition of the burner-boiler gasket. Eventually substitute it.
Check the fan’s motor: no specific maintenance is needed. In case of anomalous noises when running, check the condition of the
bearings and eventually substitute them or completely substitute the motor.
Clean and examine the gas filter cartridge and replace it if necesssary;
Remove and clean the combustion head;
Examine and clean the ignition electrodes, adjust and replace them if necessary;
Examine and clean the detection electrode/photoelement (according to the burner models), replace it if necessary, in case of
doubt, check the detection circuit, after the burner start-up;
Clean and grease leverages and rotating parts.
At least every 2 months, or more often if needed, clean the room where the burner is installed.
Avoid leaving installations, papers, nylon bags, etc., inside the room. They could be sucked by the burner and cause malfunctioning.
Check that the room’s vents are free from obstructions.
ATTENTIONwhen servicing, if it was necessary to disassemble the gas train parts, remember to execute the gas
proving test, once the gas train is reassembled, according to the procedure imposed by the law in force.

Actuators references
An incremental transducer is used to ensure position feedback. Referencing of the actuators must be performed after power-on. In
addition, at the end of each shutdown in phase 10, the actuators are referenced to ensure that individual stepping errors, which could
lead to shutdown, do not accumulate. If a position error occurs, the system switches to the safety phase (phase 01), enabling the actuators with detected position errors to be referenced. During the following phase 10, the only actuators that are referenced are those that
were not referenced before in the safety phase (phase 01). The position of the reference point can be selected depending on the type
of burner design, either the CLOSED position (<0°) or the OPEN position (>90°).

If the acutators position is exchanged (error code: 85), the burner will lockout and will try to adjust for three times, then it will lock out.
Gas proving system
Valve proving is only active when firing on gas. This is a leakage test designed to detect leaking gas valves and, if necessary, to prevent the valves from opening or ignition from being switched on. Lockout is initiated. When performing valve proving, the gas valve on
the burner side is opened first to bring the test space to atmospheric pressure. Then, the valve is closed whereupon the pressure in the
test space must not exceed a certain level, measured by the gas leakage pressure switch (PGCP). Then, the gas valve on the mains
side is opened to fill the gas pipe. When the valve is closed again, the gas pressure must not drop below a certain level. Valve proving
can be parameterized to take place on startup, shutdown, or on both phases.
Air-fuel curve points
There are 10 air-fuel curve points: T
P0 = ignition position. Only for ignition; after the ignition, the burner works between Point P1 (low flame) and point P9 (high flame)
without going back to P0.
P0 can be set everywhere irrespective of all the other points.

COMMISSIONING THE BURNER
The LMV2x complete programming must be performed on units that has never been set before or reset units (e.g. spare parts).
The programming procedure is performed by setting the following main parameters:
1
if LMV.. is a spare part, insert burner ID (parameter 113) at least 4 digit.
2 type of fuel train (parameter “201”)
3 air/fuel ratio curvepoints (Block “400”)
4 maximum load percentage (parameter “546”)
5 minimum load percentage (parameter “545”)
CAUTION: if an error message as “Loc..” appears when the unit is turned to on for the first time, press ENTER (InFo) until
the “Reset” message apperas. After few seconds, the message “OffUpr” will be displayed.
This message shows that the unit has not been programmed before or that the operating mode (fuel train) is not set yet or that the unit
has not been completely programmed. Pree keys F (Fuel) and A (Air)
at the same time unitl the display shows code and next it
will show 7 bars the first on the left is flashing. If the display shows “Off”, it means that the unitis already set, then see the instructions on
chapter “Adjsuting the burner with LMV2x already programmed”).
At the first LMV startup, the AZL display will show
It means that the unit was never set or that no mode was chisen or that some parameters have to be set furthert.
Push F (fuel) and A (Air) together untilthe display shows code and then a 7 digit dashed line blinking on the left.
Press the “+” key until the first character of the password (the default password is 9876), then press ENTER (InFo), the character now
turn to a bar while the second bar starts flashing. Press “+” until the second character is entered, then press ENTER (InFo).
Repeat the procedure until the last character si set, then press ENTER (InFo), then ENTER again until the message PArA appears:
then the first parameters block (“400”) will be shown:
Press ENTER (InFo) again, to gain access to programming the operating mode (fuel train):

Choose the fuel train by pressing ENTER, then press “+” / “-”. Press ENTER to confirm: number “1” will appear on the right side of the
display.
Then press ESC
to quit. The following display is:
Press “+” to show the first point to be set P0.
Press F and “+” to increase the opening angle of the fuel actuator “0F” until the requested value is reached (for example
12°÷15°, see below) for the ignition point; or press F and “-” to decrease the angle:
To set the air damper opening angle “0A” in the ignition point (10° for example - see below), press “A” and “+” “A” and “-” at the
same time:
LMV37:
Now the air and fuel quantities are set at the ignition point P0:
By pressing “+”, point P9 can be programmed to set the air and fuel values at the maximum output
go on as described above to the the opening angles of the air actuator (A) and fuel actuator (F):
36
CAUTION: at the first burner adjustment, it is recommended to set the maximum output P9 at the same value (or little
higher) of the ignition point, in order to safely reach point P9 next (see next paragraph).
By pressing “+” the display will show:
The burner is ready to startup. Now it is possible to re-set the curve points while the burner is operating (“warm setting”) by pressing
the ENTER (InFo) or while the burner is in stand-by mode (“cold setting”) by pressing ENTER
37
.

Once pressed button “enter” and the chain thermostats open (X5-03 terminals), the LMV.. show Ph12.Then close the chain
termostat and the unit performs the prepurge cycle (see “Phases List”) and stops at the ignition point P0 without ignition anyway.
2 By pressing “+”, the burners lights abd the air/fuel ratio can be properly set in presence of flame.
3 By pressing “+” again, the next point P1 is shown (eqaul to P0 as the unit automatically set P0=P1);
4 By pressing “+” again, the “Calc” message will be displayed: the unit is processing the sir/fuel ratio curvepoints until point P9, previuosly set. Once the processing is perfomed the calculated point P2 is shown.By pressing “+” again, the “Calc” message will be
displayed: the unit is processing the sir/fuel ratio curvepoints until point P9, previuosly set. Once the processing is perfomed the
calculated point P2 is shown.
5 By pressing “+”, it is possible to go through the processed curve until point P9 is reached.
Note: if the point doesn’t blink, servomotors are still running.
6 n order to set P9 with the gas flow rate according to the generator needs, follow this procedure:
Note: the purpose is to fully open the gas throttle and later on to adjust the gas flow rate through the gas pressure governor.
Operate smoothly opening by just a few degrees the air damper and later on increasing the gas throttle opening it by a few
degrees. Keep monitoring the flue through the flue analyser. Keep the air excess inside normal figures (from 3% to 7% residual O2)
operating by means for the air damper servomotor;

Keep increasing the air damper opening and then the gas throttle, as done in the sequence above, remebering to get the full firing
rate wih the gas throttle fully open (or the oil pressure regulator at its maximum pressure position).
See example below:



7
8
If, while opening the gas throttle, the gas flow rate was too high, reduce it only through the gas governor and keep opening the
throttle until the 60÷70° position is got.
If the gas train is equipped with a governor and a valve with an adjustable gas flow rate, fully open also this last valve, smoothly!
The gas flow rate is always set by means of the governor.
As soon as all the devices are fully open, set the gas flow rate through the governor.
Set the air damper position in order to get the reccomended air excess (3÷4.8% O2 on gas and 2.9÷4.9 % on oil).
Note1: on high flame, if the gas flow rate is changed by means of the governor, all the other points below high flame must be checked
again.

After having set the high flame point P9, keep “-” pressed for some seconds unitl “Calc” is displayed in order to have the LMV recalculating all the points:
Fuel
Air
10 the unit will automatically reach point P8 processed: check the combustion values in this point and, if necessary, change it.
11 Press “-” to go down to the lower points and check the combustion values, change the points if necessary.
Note: if in an intermediate point (for example P5), the change of the actuators position is important according to the processed point
38
P5, keep pressing “-” unitl “Calc” is displayed. The curve will be processed again downwards point P1.

deviation between two
following points: 25°max.
12 press “-” to go through the lower points and check the combustion values, if necessary change the points as described above.
13 By pressing ESC, at the end of the points adjusments, the parameter “546” (setting the maximum load) will be displayed; press
ENTER (InFo), then “+” until 100%, then press ENTER (InFo) again, ESC and then “+”.
14 The parameter “545” (setting the minimum load) is displayed: press ENTER (InFo), then “+” until 20%. Press ENTER, then press
ESC for three times. The message “oP” will be displayed as well as the load percentage at the burner is working on.
he hyphen related to the symbol “P” (highlited in the picture) will be off to show that the unit exited the programmig mode. The burner
will then work automatically, following the curve set.
.Note1: if the curvepoints settings is quit before end (by pressing ESC or for a faulty shutdown), the message “OFF UPr” (Start prevention) will be diplayed until all the curvepoints will be set.
Note2: if the gas flow rate at high flame point (maximum load) is changed by means of the pressure stabiliser, all the curvepoints must
be checked by going through the curve downwards and resetting them if necessary.
Note3: if the point does not flash, it means thet the actuators have not reached the set position yet.
Note4: if an error occurs causing a safety shutdwon during the processing of the curve, the processing itself will be interrupted.
Cold setting
The ”cold setting“ (without flame) can be performed only when all the curve points values are known (for instance, in case of replacement).
When the burner is off, if you modify one curve set point, when the burner restarts the AZL2x shows OFF UPr
(OFF UPr0 or OFF UPr1 for LMV26). The LMV.. then, requires a new "warm" startup (see procedure paragraph
"Warm Setting”) by checking again all points of curve from P0 to P9.
39
BURNER STARTUP WITH LMV2x ALREADY PROGRAMMED
Once the LMV turns on, the AZL display will show
The burners is basically factory set. The air/fuel ratio curve is set with the maximum output point P9 a little higher or equal to P0. To
adjust the burner on the plant site, adjust the maximum output point to the flow rate values really requested. Then go through the curvepoints, by pressing “+” several times to reach point P9: then adjust the air actuator position (for the air damper) and the fuel acttuator
(for the butterfly valve, in case of gas or the oil pressure governor incase of oil), by adjusting the fuel flow rate by means of the gas pressure stabiliser (for gas) or the oil pressure governor (for oil), checking the combustion valeus contemporarly. Once the burner is adjusted at the maximum output, press “-” for more than 5 seconds to process the curve downwards. The curve is then a straight line: go on
checking the combustion values point by point; change them if necessary and in case linearise the curve again.

Reset / manual lockout
The system can be manually locked by simultaneously pressing the ENTER (InFo) button and any other button on the AZL2.... This
function allows the user to stop the system from the operating level should an emergency occur. When making a reset, the following
actions are carried out:
 Alarm relay and the fault display are off
 the lockout position is cancelled
 the unit performs a reset, then it switches to stand-by
If the unit is in the lockout position, a reset can be made by pressing the InFo button for 1…3 seconds. The function is available only
when the unit is in the lockout position. Longer or shorter pushes on the button do not produce a reset so that the system maintains the
lockout position.
