Page 42 PART II: INSTALLATION ADJUSTING THE GAS VALVES GROUP Multibloc MB-DLE The multibloc unit is a compact unit consisting of two valves, gas pressure switch, pressure stabilizer and gas filter. C VS The valve is adjusted by means of the RP regulator after slackening the locking screw VB by a number of turns.
Page 43 PART II: INSTALLATION 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 bur- ner control panel.
Page 44 MIN position.Attention! if it is necessary to change the head position, repeat the air and gas adjustments described above. Fig. 13 KP73 Only if necessary, change the combusiton head position: to let the burner operate at a lower output, loose the VB screw and move pro- gressively back the combustion head towards the MIN position, by turning clockwise the VRT ring nut.
Page 45 PART II: INSTALLATION Oil thermostat adjustment Progressive and fully modulanting oil burners are equipped with electronic multi-thermostat Danfoss MCX, whose operation is con- trolled by thyristor. (for details refer to the attached technical documentation) Fig. 14 - Danfoss MCX Fig. 15 - Probe connections (Danfoss MCX) The oil viscosity at the nozzle, should be about 1,5 °E, which guarantees correct and safe functioning of the burner.

Page 97 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.
Page 98 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: if LMV.. is a spare part, insert burner ID (parameter 113) at least 4 digit. type of fuel train (parameter “201”) air/fuel ratio curvepoints (Block “400”) maximum load percentage (parameter “546”)

Page 101 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.
Page 102 Warm setting 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. By pressing “+”, the burners lights abd the air/fuel ratio can be properly set in presence of flame.

Page 207 M12927CA OPERATIVE MODES When the instrument is powered, it starts immediately to work according to the parameters values loaded in its memory. The instrument behaviour and its performance are governed by the value of the stored parameters. At power ON the instrument can start in one of the following mode depending on its configuration: Automatic Mode In Automatic mode the instrument drives automatically the control output according to the parameter value set and the set point/measured value.

Page 228 APPENDIX: PROBES CONNECTION To assure the utmost comfort, the control system needs reliable information, which can be obtained provided the sensors have been installed correctly. Sensors measure and transmit all variations encountered at their location. Measurement is taken based on design features (time constant) and according to specific operating conditions.With wiring run in raceways, the sheath (or pipe) containing the wires must be plugged at the sensor's terminal board so that currents of air cannot affect the sensor's measurements.

Page 234 USER MANUAL OF MULTI-THERMOSTAT MCX06C MCX06C is a multi-thermostat with four 100k NTC inputs. It can control up to 4 temperatures showing them (not more than 2 at the same time) on a couple of displays. It is used to check and adjust oil heater temperatures. User interface: Device: ESC button/...
Page 235 Menu: To enter the menu below, keep pushing ENTER for more than 3 s. Menu code Sub-menu Function Notes code Probes values You can see in sequence the 4 probe values (UP and DOWN keys): the probe code is on display A (Pb1,..., Pb4) and the probe value is on display B (not fitted or out of work probes show “----“).
Page 236 Set point adjustment: All the parameters inside the Par menu are locked by a password. The user can modify only set points (menu rEG), without using any passwords. The oil viscosity at the nozzle, should be about 1,5° E, which guarantees correct and safe functioning of the burner. The temperature values in the table, guarantee the respect of that parameter and are valid when the pre heating tank is installed on the burner.
