Addendum 4: LMV52... with O
2
trim
control and O
2
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
2
trim control, con-
trol of a maximum of 6 actuators, control of a VSD, and acquisition of cumulated fuel
consumption and current fuel throughput. The LMV52... system uses an O
2
sensor
(QGO20...), an external O
2
module, and the standard components of the LMV51... sys-
tem.
The PLL... O
2
module is a detached measuring module for the QGO20... sensor and
for 2 temperature sensors (Pt1000 / LG-Ni 1000). The module communicates with the
LMV52… via CAN bus.
The fuel meters must be connected directly to the fuel-related inputs of the basic unit.
On the AZL5... display and operating unit, the individual consumption values can be
read out and the meter readings can be reset.
