19.8 PLL52 O2 module

The PLL52 and QGO20 must be connected to enable the residual oxygen control
system to be activated on the LMV52.
A combustion air and flue gas temperature sensor can also be connected as an option,
enabling, for example, the combustion efficiency to also be calculated and displayed.
The PLL52 is to be connected to the LMV5 via CAN bus. The PLL52 must be located in
the vicinity of the QGO20 (<10 m), aimed at keeping interference on the sensitive
detector lines as low as possible. For sensor heating, the PLL52 requires a separate
mains connection facility.
