4.3.1.2.1 Automatic
alignment of sensitive parameters
When a multi inverter system is detected, the unit checks for consistency of the set parameters. If the
sensitive parameters are not aligned on all inverters, the display of each inverter shows a message
requesting whether to transfer the configuration of the specific inverter to the entire system. On acceptance,
the sensitive parameters on the inverter where confirmation is given are distributed to all other inverters in
the series.
If there are configurations incompatible with the system, the configuration cannot be aligned from these
inverters.
During normal operation, modification of a sensitive parameter on an inverter will cause automatic alignment
of the parameter on all other inverters without any request for confirmation.
NOTE:
Automatic alignment of sensitive parameters has no effect on all other types of parameter
.
In the particular case of inserting an inverter with default settings in the series (in the case of an inverter
which replaces an existing model or an inverter with restored factory settings), if the configurations applied,
with the exception of factory settings, are consistent, the inverter with the factory settings will automatically
take on the sensitive parameters of the series.
4.3.1.3
Parameters with optional alignment
These are the parameters that are admissible even if not aligned with other inverters. Each time these
parameters are modified, when SET or MODE is pressed, the request is displayed whether to modify the
entire communicating inverter series. In this way if the series has all the same settings, the same data does
not need to be set on all inverters.

4.4 Multi-inverter
settings
When a multi inverter system is switched on, the addresses are assigned automatically and, by means of an
algorithm, an inverter is nominated as the settings leader. The leader decides on the frequency and order of
start-up of each inverter in the series.
The settings mode is sequential (inverters start one at a time). When start-up conditions are enabled, the first
inverter starts, and when this reaches maximum frequency, the next one starts, and so on. The order of start-
up is not necessarily ascending according to the machine address, but depends on the hours of operation;
see ET: Tempo di scambio par. 6.6.9.
When the minimum frequency FL is used, and there is only one inverter operative pressure surges may
occur. Depending on the case, pressure surges may be inevitable and may occur at the minimum frequency
when this value, in relation to the hydraulic load, causes a pressure level greater than the required value. On
multi inverter systems, this problem remains limited to the first pump that is started up, as on the subsequent
pumps the situation is as follows: when the previous pump reaches the maximum frequency, the next one
starts up at the minimum frequency to then reach the maximum frequency. When the frequency of the pump
at maximum is reduced (obviously through to the minimum frequency limit) the pump activation overlaps,
which while observing minimum frequency rates, does not cause pressure surges.
