- Page 61 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 68 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.
