7.6.2.3 Priorities
The priority of the gen-set within the group is given by the setpoint Pwr management: Priority. Lower
number represents "higher" priority, i.e. a gen-set with lower number starts before another one with
higher number. In other words, the setpoint Pwr management: Priority means order in which gen-sets
are started and connected to the bus. An example is shown on the figure below. There are four gen-
sets with following choice of setpoints:
