The control system is made of the Siemens LMV central unit (6) that performs all the burner control functions and of the Siemens AZL
local programming unit (10) that interfaces the system with the user.
Main features:
zno mechanical linkages
zbuilt-in burner control box
zbuilt-in gas proving system
zmore flame checking devices available for several applications
zPID load controller
zup to six actuators can be controlled. Each of them is independent for the best burner setup
zbest air/fuel ratio. Repeatability and precision of set adjustments
zModbus communication
zmultilevel password
zsettings via PC
zadjustable prepurging time (according to the relevant Standards)
zcontinuous ventilation
zpost purging (adjustable time)
zproving system settable to on and off
zadjustable proving system time for all the valve volumes
zload controller settable to on and off
zthermal shock protection function settable to on and off (for cold starts)
zcontinuous operation and flame detection probe

USER SETTINGS
Go on adjusting the burner.
Users can set only the LMV parameters that can be accessed without password: (see “Adjusting the temperature set-point”).
The Siemens AZL User Interface allows programming the Siemens LMV control box and monitoring the system data.
The user interface is made of:
1. display: it showes menus and parameters
2. ESC key (previous level): it goes back to the prevoius level menu or exits the programming mode without changing data.
3. ENTER key (next level): it confirms the data changing and jumps to the next menu/parameter.
4. SELECT keys: they select a menu item and change the parameter values.
To know the actuator functions, proceed as follows:
1 remove the actuator covers
2 check the number of the LV green LED blinks for each actuator:
Blinks Actuator function
1 blink air damper actuator
2 blinks gas butterfly valve actuator
3 blinks oil pressure governor actuator
4 blinks auxiliary actuator
5 blinks auxiliary actuator
6 blinks auxiliary actuator
CAUTION: it is recommended not to adjust the actuators. Anyway, never press the actuator red button, otherwise the fun-
damental parameters, necessary for the burner operation, will be cancelled. The burner will therefore continuously lock out.

Start-up procedure
1 Turn the burner on according to the following:
zual fuel burners: choose the requested fuel by means of the related control panel switch
zone fuel burners: turn the burner on by means of the burner main switch (placed on the burner control panel)
2 the LMV controller starts the system test cycle: the AZL display shows the System Test message; at the end of the test, it shows
the main page and the system stops (the safety chain is open) waiting for the startup enabling signal (standby - Program phase no.
12)
3 check the fan motor rotation;
4 (light/heavy oil burners) with the electrical panel open, prime the oil pump acting directly on the related CP contactor (see next pic-
ture): check the pump motor rotation and keep pressing for some seconds until the oil circuit is charged;
5 bleed the air from the Mpressure gauge port (see next picture) by loosing the cap without removing it, then release the contactor.
6 make the safety chain enabling the system to start up
7 the combustion cycle starts:
- Prepurging (program phase no.30)
- Driving to ignition position (program phase no.36)
- Ignition position (program phase no.38)
- Fuel (the fuel solenoid valves open)
- Flame (the flame lights up)
- Driving to low flame (the actuator drives to low flame).
NOTE: the C and A, on the .
Once the ignition cycle ends, the main page is shown:

by means of the arrow keys, select “Access w-out pass” (access without password - user level), confirm by pressing ENTER.
The other levels require password reserved to the Technical Service, to the Manifacurer, etc.
The menu accessed without password is the following:
Choose “LoadController” and press ENTER: the following menu is shown:
Choose “ControllerParam” and press ENTER: the following menu is displayed:
Choose “SetPointW1” and press ENTER:
Curr: it shows the current set-point; use the arrows keys to change it.
NOTE: the available range depends on the probe used; the measure unit of the detected data and its relevant limits are set by “Service”
level parameters.
Once the new set-point is set, confirm by pressing ENTER, otherwise exit without changings by pressing ESC.
Press ESC to exit the set-point programming mode.
Once the temperature set-point W1 is imposed, set the Switch-on (SDon) and the Switch-off (SDoff) point of the 2-position controller:
To set these values, select the item SD_ModOn (SDOn), by scrolling down the “Load controller” menu with the arrow keys and press

Cold start thermal shock (CSTP)
If there is a steam boiler that must start up cold in the plant, the fireman will heat the boiler keeping the burner at the lowest output to
prevent thermal shocks.
The LMV control box provides the CSTP (Cold Start Thermal Schock) function that is already set by the Technical service (access by
reserved password).
if this function is enabled, when the burner starts upthe “Thermal shock protection activated” message will be shown.
If this function is not enabled, after startup, the burner will rapidly increase the load according to the requested value and, if necessary,
to the maximum output.
Manual mode
To by-pass the thermal protection or not to let the buner operate in high flame stage after ignition, the manuale mode is provided.
To choose the manual mode (Manual Operation), use the SELECT arrow keys
Items to be set are the fllowing:
SetLoad: to set the required load percentage
set the required percentage and confirm by pressing ENTER; press ESC to exit.
choose “Autom/Manual/Off
three modes are provided:
Automatic: automatic operation
Burner on: manual operation
Burner off: burner in stand-by
If the BurnerOn mode is choosen,the burner does not follow the modulator and probe settings, but operates at the set load.
Caution: if BurnerOff mode is selected, the burner stays in stand-by
Caution: in the BurnerOn mode, the safety thresholds are set by the Technical Service.
