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.
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.
