These settings allow a masking of a particular load range.
This is useful for combustion resonances that occur at a particular load (firing rate).
For example: if LoadMaskLowLimit is set to 32% and LoadMaskHighLimit is set to 42%,
S
the LMV5 will modulate from 32% to 42% without stopping.
Def Low = 0%, High = 0% (No masking)
The first six parameters appear under both fuels GasSettings , and OilSettings.
Each fuel can have a different settings.
One of the last two parameters will appear depending on which fuel is currently selected.
1. activated - This activates the specific actuator.
2. deactivated - This de-activates the specific actuator.
3. air influen(ced) - This means that the actuator (VSD) will respond,
to achieve an oxygen level in the stack.
This setting is only for O2 sensor equipped LMV52. O2 control must also be activated.
O
Fuel actuators cannot be set to air influenced.
Note : Any actuator (VSD) can be activated or deactivated on a LMV52.
The only actuator that can be changed on LMV51 is the Aux Actuator.
StartPoint Op - This parameter controls what curve point the LMV5 drives to in Phase 54.
The LMV releases to this curve point, typically point 1
Range is 0-15 (or the highest point on the curve), Default is xx (or highest point) g ( g
AZL software version 4.50 or higher is needed to view or change this parameter.
1) Automatic - Enable the burner allowing it to respond to setpoints.
2) Burner off - Manually turn the burner off setpoints are ignored.
U
3) Burner on - Manually turn the burner on setpoints are ignored. (See ManualOperation>SetLoad)
For normal operation this should be placed in automatic. Def = Automatic
This parameter is also available under Manual Operation> Autom/Manual/Off
Controls the speed at which the Actuators / VSD will ramp during normal operation (fuel valves open).
Do not set to less than the slowest actuator.
Range = 30-120sec Def / Typ = 30s (SQM 45 - 10 sec, SQM 48.4 - 30 sec, SQM 48.6 -60 sec)
Controls the speed at which the LMV will ramp in multistage operation.
S
Range =10-60sec Def / Typ =10sec
Controls the speed at which the actuators / VSD will ramp when the fuel valves are closed.
Do not set less than the slowest actuator.
Range = 30-120sec Def = 10 sec Typ = 30 sec
