  • Page 85 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 86: Commissioning The Burner

    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 87 the types of fuel trains are the following: Param.

  • Page 88 Lo 3-stage In the example the Gmod gas train has been set (Configuration “1”). Choose the fuel train by pressing ENTER, then press “+” / “-”. Press ENTER to confirm: number “1” will appear on the right side of the display.
  • Page 89 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 90: Warm Setting

    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.

Fuel 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”...
  • Page 92 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.
  • Page 93 Set the air/fuel ratio curvepoints as described on chapter “Programming the LMV2x” Note: the other phases are Ph60 = operation (OP= in modulation) Ph62 = travelling to shutdown Ph70 = off but in prepurge after the burntime Ph72 = travelling to postpurging Ph74 = postpurge (countdown is displayed) Press ESC the parameter “546”...
  • Page 94 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 ...
  • Page 95 Entering the Parameter levels By means of a proper use of the keys, it is possible to enter the various level parameters, as shown in the following flow chart: The burner and consequently the LMV2x.. are factory set; the air and fuel curves as set as well.
  • Page 96 Info level To enter the Info level, proceed as follows: in any menu position, press keys + and - at the same time, then the program will start again: the display will show OFF. , until the display will show InFo, Press the enter (InFo) key then il will show the first code (167) flashing, on the right side it will show the data entered.
  • Page 97 10 Press InFo for more than three seconds or for more than three seconds orto return to the normal display. If a message like the one below is shown during operation, it means that the burner is locked out and the Errore code is shown (in the example “error code:4”); this message is alternating with another message Diagnostic code (in the example “diagnostic code:3”).
