This switch allows for three positions:
– ILS (Isochronous Load Sharing): both connected genera-
tors give their full proportional load immediately
– Blend: the proportional load of the brought in generator is
slowly built up (time adjustable between 2 s and 5 min), af-
ter selector switch S6 has been set to ‘Load’
– Command: allows a fixed power output of the generator,
irrespective of the load
6 6HOHFWRUVZLWFK8QORDG/RDG
This switch only applies to the ‘Blend’ mode (selector switch
ILS/Blend/Command in position ‘Blend’).
The central position of the three position selector switch is used
for ‘ILS’ mode. The other two positions are:
– Unload: one generator is enough to supply the full load, but
to prevent the other generator from idling, it still supplies
± 10 % (adjustable value) while the other one supplies
± 90 % of the full load
– Load: both connected generators deliver equal percentages
of their full load capacity
