3.5  Enabling and disabling the motor 

Once the first configuration has been performed with the wizard, the [RUN/STOP] key can be used to disable and re-
enable the motor control. If the inverter is running (green led ON yellow led ON) or is stopped (green led OFF yellow 
led ON), the motor control can be disabled by pressing the [RUN/STOP] key. 
When the inverter is disabled, the yellow led blinks and the green led is always off. 
To re-enable pump control it is sufficient to press the [RUN/STOP] key again. 
The [RUN/STOP] key can only disable the inverter, it is not a start command. The running status is decided only by 
the regulating algorithms or by the inverter functions. 
The key function is active on all the pages. 
 

4  MULTI INVERTER SYSTEM 

 

4.1  Introduction to multi inverter systems 

A multi inverter system comprises a pump set made up of a series of pumps with delivery outlets all conveying to a 
single manifold. Each pump of the set is connected to its own inverter and the various inverters communicate via a 
special connection. 
The maximum number of pump-inverter elements possible in a group is 8. 
A multi inverter system is mainly used toper: 

  Increase the hydraulic performance with respect to a single inverter 

  Ensure operation continuity in the event of a fault on a pump or inverter 

  Partition maximum power 

 

4.2  Setting up a multi inverter system 

The pumps, motors and inverters in the system must be identical versions.  The hydraulic system must be as 
symmetric as possible in order to achieve a hydraulic load evenly distributed on all the pumps.  
The pumps must all be connected to a single delivery manifold.  

 

Since the pressure sensors are each inside the plastic body, you must take care not to place non-return 
valves between one inverter and another, otherwise the inverters may read different pressures from each 
other and give as a result a false mean value and an abnormal regulation.

 

 

For the operation of the booster set, the inverters must be of the same type and model; they must also be 
the same for each inverter-pump pair: 

 

  type of pump and motor 

 hydraulic 

connections 

   rated frequency 

 minimum 

frequency 

 maximum 

frequency 

 

 

4.2.1  Communication 

The inverters communicate with each other through the dedicated 3-wire connection. 
For the connection, see par. 2.3.6. 

 

4.2.2  Remote sensor in multi-inverter systems 

To use the pressure control functions with a remote sensor, the sensor can be only 1 connected to one of the inverters 
present. Even several remote pressure sensors can be connected, up to one for each inverter. If several sensors are 
present, the regulating pressure will be the mean of all the connected sensors. 
To ensure that the remote pressure sensor can be visible by the other inverters, the multi-inverter communication 
must be correctly connected and configured on all the inverters, and the inverter to which it is connected must be On.  

 

4.2.3  Connection and setting of the optical coupling inputs 

The inputs of the inverter are photocoupled (see para. 2.3.3 and 6.6.15) this means that galvanic separation of the 
inputs from the inverter is guaranteed, to enable the functions for the float, auxiliary pressure, system disable, and low 
pressure on intake. The functions are indicated respectively by the messages F1, Paux, F3, F4. If activated, the Paux 
function boosts the pressure in the system to the set pressure, see par. 6.6.15.3. The functions F1, F3, F4 stop the 
pump for 3 different reasons, see par. 6.6.15.2, 6.6.15.4, 6.6.15.5. 
When using a multiple inverter system, the inputs must be used with the following settings:  

  the contacts that perform the auxiliary pressures must be connected in parallel on all the inverters so that the 

same signal arrives on all the inverters.
