19.10 Configuring the system

(Description of the plant-dependent basic configuration)
First, make all configurations as described in detail with the LMV51.

19.10.1 Actuators / VSDs

When activating the actuators / VSDs via menu section RatioControl, parameterization
comprises activated and deactivated and, in addition, air influen. Air-influencing (or air-
regulating) actuators have an impact on the amount of air. The actuators defined as air
influen actuators are used for O2 trim control. Basically, all actuators having an impact
on the air volume are to be parameterized as air influen. In exceptional cases, a truly
air-regulating actuator can be excluded from O2 trim control by setting it to activated.
Note!
If the parameterization is changed, O2 trim control must be readjusted.
deactivated: Actuator is not active
activated: Actuator is active but has no impact on the air volume. Actuator is not
used for O2 trim control
air influen: Actuator is active and has an impact on the air volume. Actuator is
used for O2 trim control
Parameter Air actuator (deactivated, activated, air influen)
Auxiliary actuator 1 (deactivated, activated, air influen)
Auxiliary actuator 2 (deactivated, activated, air influen)
Auxiliary actuator 3 (deactivated, activated, air influen)
VSD (deactivated, activated, air influen)

19.10.2 Parameterizing the type of fuel

For calculating precontrol and combustion efficiency, the type of fuel must be selected.
Also refer to chapter Setting fuel-air ratio control.
For firing on gas, there are 4 preprogrammed fuel types available, plus 1 type of fuel
that can be defined by the user.
For firing on oil, there are 2 preprogrammed types of fuel available, plus 1 type that can
be defined by the user.
Parameter Gas: Type of Fuel (user def, naturalGasH, naturalGasL,
propane, butane)
Oil: Type of Fuel (user def, LightOilLO, LightOilHO)
