Example 1:
A pump set composed of 2 devices (N=2 detected automatically) of which
1 set active (NA=1), one simultaneous (NC=1 or NC=NA since NA=1)
and one as reserve (IC=reserve on one of the two devices).

reserve will start and work by itself (even though it does not manage to
bear the hydraulic load and the pressure achieved is too low). If it has a
fault, the reserve device steps in.
Example 2:
A pump set composed of 2 devices (N=2 detected automatically) in which
all the devices are active and simultaneous (factory settings NA=N and
NC=NA) and one as reserve (IC=reserve on one of the two devices).

as reserve), but this may be useful in case of necessity when a greater
hydraulic load occurs.
Example 3:
A pump set composed of 4 devices (N=4 detected automatically) of which
3 set active (NA=3), 2 simultaneous (NC=2) and 1 as reserve (IC=reserve
on two devices),
The result obtained is the following: at the most 2 devices will start at
the same time. The operation of the 2 that can work simultaneously will
take place in rotation among 3 devices so as to respect the maximum
exchange time of each (ET). If one of the active devices develops a fault
no reserve starts up because more than 2 devices cannot start at one
time (NC=2) and there are still 2 active devices present. The reserve
intervenes as soon as another of the 2 develops a fault.
