- Page 5 PART I: SPECIFICATIONS PART I: SPECIFICATIONS BURNERS FEATURES These burners are designed to be installed into boilers provided with very big combustion chamber but the tube nest very close to the burner stokhole. The flame produced by this burner series is very short, but has the energy necessary to take up all the combustion chamber and then exchange this energy to the water, as to get very high efficiency.
- Page 6 PART I: SPECIFICATIONS Matching the burner to the boiler To correctly match the burner to the boiler verify the necessary input and the pressure in combustion chamber are included in the bur- ner performance curve; otherwise the choice of the burner must be revised consulting the burner manufacturer. Burner model identification Burners are identified by burner type and model.

- Page 113 COD. M07979CD rel. 3.2 01/13 RECOMMENDATIONS FOR LMV5x CONNECTIONS Connections affected by EMC noises are related to the bus cable (actuator line cable, PLL52), detection probe cable, speed sensor cable, 4-20mA signal cable that controls the VSD. Input and power cables (400V e 230V) must be laid separately from the signal cables. The bus cable between control panel and burner and between burner and PLL52 board (used when O2 trim control must be perfomed) must be laid separately and far from power cables.

- Page 120 Addendum 4: LMV52... with O trim control and O module General The LMV52... system is an extended LMV51... system. A special feature of the LMV52… is control of the residual oxygen content to increase the boiler’s efficiency. In addition to the features of the LMV51..., the LMV52... provides O trim control, con- trol of a maximum of 6 actuators, control of a VSD, and acquisition of cumulated fuel consumption and current fuel throughput.
- Page 121 The maximum cable length between transformer and CAN bus users is dependent on Determination of the the type of cable (cross-sectional area), the number of actuators and the type of actua- maximum cable length tor used (current). The following graphs can be used to determine the maximum CAN bus cable lengths between the transformer and group of actuators or the AZL5…, depending on the rele- vant influencing factors.

- Page 125 Notes on example 3a / 3b CAN bus cable with LMV52... and more than 4 actuators and O2 module PLL52... On LMV52... applications with more than 4 actuators (SQM45...), a second transformer is required for powering the extra actuators. In that case, transformer 1 powers the LMV52... basic unit, the AZL5..., and the first 4 actuators.
- Page 126 O2 module In comparison with the LMV51... system, the extra components to be connected with the LMV52… system are the O module and the O sensor QGO... and, optionally, the combustion air and flue gas temperature sensors. The O module is to be connected to the basic unit via the CAN bus.
