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
1 Air damper
2 Fuel 1 (gas)
3 Fuel 2 (oil)
Auxiliary actuator 1 (e.g. mixing
4
equipment)
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.

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%.
