As it is shown on both figures above, the addional gen-set is added once the actual load reserve is
below the level given by the setpoint
Pwr management:
#LoadResStrt X.
The addional gen-set is
removed once the actual load reserve is above the level set by
Pwr management:
#LoadResStop X
.
The green dashed line depicts the value of load at which the additional gen-set is requested to start.
This value of the load value is linked with the setpoint
Pwr management:
#LoadResStrt X
in following
way:
Sum of Nominal power - #LoadResStrt X =
Value of load when additional gen-set requested to start
E.g.:
700 kW
– 100 kW =
600 kW
The red dashed line depicts the value of load at which the additional gen-set is requested to stop. This
value of the load value is linked with the setpoint
Pwr management:
#LoadRes Stop X
in following
way:
Sum of Nominal power - #LoadResStop X =
Value of load when additional gen-set requested to stop
E.g.:
700 kW
– 125 kW =
575 kW
There are 4 levels for starting and stoping gen-sets.

.
#LoadResStrt 2

considered if LBI:
Load res 2 activated

#LoadResStop 3
considered if LBI:
Load res 3 activated
#LoadResStrt 4
/
#LoadResStop 4
considered if LBI:
Load res 4 activated
The option of switching the load reserves by LBI may be usefull in cases appliances with important
power consumption are expected to be connected to the bus.

:
All controllers cooperating together in Power management must have the same load reserve set
selected.
It is possible to use virtual shared peripheries for distribution of the binary signal to activate LBI
Load

among controllers over the CAN bus. For further information, please refer to the chapter
Shared Inputs and Outputs.
