Automatic alignment of sensitive parameters
When a multipump system is detected, the compatibility of the set pa-
rameters is checked. If the sensitive parameters are not aligned among
all the devices, a message appears on the display of each device asking
whether you want to propagate the configuration of that particular device
to the whole system. If you accept, the sensitive parameters of the device
on which you answered the question will be distributed to all the devices
in the chain.
If there are configurations that are not compatible with the system, these
devices are not allowed to propagate their configuration.
During normal operation, changing a sensitive parameter of a device re-
sults in the automatic alignment of the parameter on all the other devices
without asking for confirmation.
NOTE: The automatic alignment of the sensitive parameters has no effect
on all the other types of parameters.
In the particular case of inserting a device with factory settings in the
chain (a device replacing an existing one or a device on which the factory
configuration has been restored), if the present configurations with the
exception of the factory configurations are compatible, the device with
factory configuration automatically assumes the sensitive parameters of
the chain.

Parameters with optional alignment
These are parameters for which it is tolerated that they may not be
aligned among the various devices. At each change of these parameters,
when you come to press SET or MODE, you are asked if you want to
propagate the change to the entire communication chain. In this way, if all
elements of the chain are the same, it avoids setting the same data on all
the devices

9.4.6 First start of the multipump system
Make the electric and hydraulic connections of the whole system as
described in par 2.1.1, 2.2.1 and par 3.1.
Switch on the devices and create the associations as described in para-
graph 7.5.5 – AS: Association of devices.
9.4.7 Multipump adjustment
When a multipump system is switched on, the addresses are automati-
cally assigned and an algorithm selects one device as the adjustment
leader. The leader decides the speed and starting order of each device in
the chain.
The adjustment mode is sequential (the devices start one at a time).
When starting conditions occur, the first device starts, when it has
reached maximum speed the next one starts, and then the others in
sequence. The starting order is not necessarily in ascending order ac-
cording to the machine address, but it depends on the working hours
done see 7.6.11 - ET: Max. switching time
