6.2 Activating / deactivating the actuators

If the auxiliary actuator is not needed, it must be deactivated.
This can be carried out separately for both fuels.
For LMV50 and LMV51.3, the variable speed drive / auxiliary actuator 3 (for flue gas
recirculation) can be activated.
The required actuators must be activated.
If O2 trim control or a variable speed drive is used, the actuators that have an impact
on the air volume must be parameterized to air influen.
Parameter:
AuxActuator (deactivated / Damper act)
AuxActuator (deactivated / Damper act /
activated VSD / AUX3 / VSD + AUX3)
AirActuator (deactivated / activated)
AirActuator (deactivated / activated / air influen)
GasActuator or OilActuator (deactivated /
activated)
AuxActuator 1 (deactivated / activated / air
influen)
AuxActuator 2 (deactivated / activated / air
influen)
AuxActuator 3 (deactivated / activated / air
influen)
VSD (deactivated / activated / air influen)
Meaning:
deactivated Deactivated
Damper act AUX actuator 1 - damper (mixing device) active
activated VSD VSD activated
AUX3 AUX actuator 3 - damper (flue gas recirculation damper) active
VSD + AUX3 VSD and AUX actuator 3 - (flue gas recirculation -) damper active
air influen Damper / VSD activated that have an impact on the combustion air.
These are also driven to the prepurge positions during
standardization, refer to chapter Configuring speed acquisition.
∂
The LMV5 system uses one burner actuator for gas and one for oil as standard
(NumFuelActuators = 2)
∂
It is possible to use one common actuator for the fuel damper and the oil pressure
controller (NumFuelActuators = 1).
It is then still possible to parameterize independent curves for both types of fuel.
Parameter NumFuelActuators (1 / 2)
Note!
If the NumFuelActuators parameter was set to «1»,
the common fuel actuator must be addressed as a GasActuator.
