7.7.2 NC: Simultaneous devices
Sets the maximum number of devices that can work at the same time.
It may have values between 1 and NA. The default value of NC is NA,
this means that even if NA increases, NC will have the value NA. If a

On the same menu page you can also see (but not change) the other
two system parameters linked to this, that is N, the number of devices
present, read automatically by the system, and NA, the number of active
devices.

minimum starting priority is associated with it, this means that the device
with this setting will always start last. If a number of active devices is set
that is one lower than the number of devices present and if one element
is set as reserve, the effect obtained is that, if there are no problems, the
reserve device does not participate in regular pumping; instead, if one of
the devices that participates in pumping develops a fault (maybe loss of
power supply, tripping of a protection, etc.), the reserve device will start.

of this control depends on the set GP and GI parameters. To cope with
the different behaviour of the various types of hydraulic plants where the
system can work, the inverter allows the selection of parameters different
from those set by the factory. For nearly all plants the factory-set GP
and GI parameters are optimal. However, should any problems occur in
adjustment, these settings may be varied.

7.7.1 - NA: Active devices
Sets the maximum number of devices that participate in pumping.
It may have values between 1 and the number of devices present (max
4). The default value for NA is N, that is the number of devices present
in the chain; this means that if devices are added to or removed from
the chain, NA always has the value of the number of devices present,

can or want to be able to keep running, and if you want to keep one or
