NOTE: To remove a module, disconnect any dangerous voltage and repeat the operations from step 5 to step 2 in reverse. Press
in the point indicated with  to release the module and remove it ().
When the 8BGA power factor controller is powered on, it automatically recognises the modules that have been mounted.
If the system configuration has changed with respect to the last saved, (one module has been added or removed), the base unit
asks the user to confirm the new configuration. In case of confirmation, the new configuration will be saved and will become
effective, otherwise the mismatch will be shown at every subsequent power-on of the system.
The present system configuration is shown in the dedicated page of the display (expansion modules), where it is possible to see
the number, the type and the status of the modules. The I/O numbering is shown under each module.
The status (energised/de-energised) of every single I/O and communication channel is highlighted in reverse

11.1 Additional resources

The expansion modules provide additional resources that can be used through the dedicated setup menus.
The setup menus related to the expansions are always accessible, even if the expansion modules are not physically fitted.
Since it is possible to add more than one module of the same typology (for instance two communication interfaces), the setup
menus are multiple, identified by a sequential number.
The following table indicates how many modules of each group can be mounted at the same time. The total number of modules
must be less or equal than 4.

11.2 Communication
The 8BGA power factor controller supports a maximum of 2 communication modules, indicated as COMn. The communication
setup menu is thus divided into two sections (n=1 ... 2) of parameters for the setting of the ports.
The communication channels are completely independent, both for the hardware (physical interface) and for the communication
protocol.
The two channels can communicate at the same time.
Activating the Gateway function it is possible to use a 8BGA power factor controller with both an Ethernet port and a RS485 port,
that acts as a bridge over other power factor regulators equipped with RS-485 only, in order to achieve a more economic
configuration (only one Ethernet port).
In this network, the power factor controller with Ethernet port will be set with both communication channels (two among COM1,
COM2) with Gateway function set to ON, while the other power factor relays will be configured normally with Gateway = OFF.

12 INPUTS, OUTPUTS, INTERNAL VARIABLES, COUNTERS, ANALOG INPUTS

The inputs and outputs are identified by a code and a sequence number. For instance, the digital inputs are identified by code
INPx, where x is the number of the input. In the same way, digital outputs are identified by code OUTx.
The sequence number of I/Os is simply based on their mounting position, with a progressive numbering from left to right.
It is possible to manage up to 4 analog inputs (AINx), connected to external analog sensors (temperature, pressure, flow etc). The
value read from the sensors can be scaled to any unit of measure, visualized on the display and transmitted on the communication
bus. The value read from analog inputs is shown on the dedicated display page. They can be used to drive LIMx limit thresholds,
that can be linked to an internal or external output.
The expansion I/O numbering starts from the last I/O installed on the base unit. For example, with OUT1...OUT8 digital outputs
on the base unit, the first digital output on the expansion modules will be OUT9. See the following table for the I/O numbering:
