logic for the various inputs with the same name; that is, for the same input, either normally open contacts are used for all the inverters
or normally closed ones.
4.3 Multi inverter operating parameters
The parameters displayed on the menu, in a multi-inverter configuration, can be classed as follows:
Read-only parameters
•
Local parameters
•
Multi inverter system configuration parameters
•
o Sensitive parameters
o Parameters with optional alignment
4.3.1 Parameters related to multi inverter systems
4.3.1.1 Local parameters
These are parameters that can differ from one inverter to another and in some cases actually need to be different. For these
parameters, automatic alignment of inverter configuration is not admitted. In the case of manual assignment of addresses, these must
all be different.
List of local parameters for inverters:
 CT Contrast
 FP Test frequency in manual mode
 RT Direction of rotation
 AD Address
 IC Reserve configuration
 RF Fault and warning reset
4.3.1.2 Sensitive parameters
These are parameters that must be aligned on the entire series for control purposes.
List of sensitive parameters:

P1 Input 1 auxiliary pressure

P2 Input 2 auxiliary pressure
