6.1 Actuator addresses
The functions of the dampers are ready assigned to the addresses and are defined as
follows:
Addresses LMV51.0 / LMV51.1 Parameter
1 Air damper AirActuator
2 Fuel 1 (gas) GasActuator
3 Fuel 2 (oil) OilActuator
4
Auxiliary actuator 1 (e.g. mixing
equipment)
AuxActuator
Β
Note!
Up to 4 actuators can be connected to the LMV51.0 / LMV51.1.
Of these, up to 3 actuators can be controlled simultaneously.
The fuel actuators cannot be controlled simultaneously.
Addresses LMV50 / LMV51.3 Parameter
1 Air damper AirActuator
2 Fuel 1 (gas) GasActuator
3 Fuel 2 (oil) OilActuator
4
Auxiliary actuator 1 (mixing equipment)
¹)
AuxActuator
6
Auxiliary actuator 3 (flue gas
recirculation) ¹)
AuxActuator
VSD ¹) AuxActuator
¹) Possible combinations: Auxiliary actuator 1 or VSD or auxiliary actuator 3 or
VSD + auxiliary actuator 3
Β
Note!
Up to 4 actuators and 1 variable speed drive can be connected to the LMV50 /
LMV51.3. Of these, up to 3 actuators can be controlled simultaneously.
The fuel actuators cannot be controlled simultaneously.

Β
Note!
Up to 6 actuators and 1 variable speed drive can be connected to the LMV52. Of
these, up to 5 actuators can be controlled simultaneously.
The fuel actuators cannot be controlled simultaneously.
Actuators 1...6 are controlled with a resolution of 0.1°. They can be adjusted between
0° and 90°. The VSD is controlled with a resolution of 0.1%. It can be adjusted between
0% (off, prepurge / postpurge fan speed) or 10% (ignition and operating speeds) and
100%.
