SUMMARY :
DESCRIPTION :
The SFX+V2 is an adjustable device for the control and
automatization of declogging equipment, whose declogging is done
by compressed air injections.
It can manage filters organized in several cells (= compartments)
and with several compressed air reservoirs.
Depending on the configuration, declogging is carried out in
ONLINE or OFFLINE mode.
The SFX+V2 manages various controls, such as electric
consumption of SV, position of cell insulation, compressed air
consumption on tanks, dust emissions ...
The SFX+V2 has a historical record of faults and events.
The SFX+V2 incorporates the functional program corresponding
to the configuration of the filter. Adjustment of some parameters can
be done easily on site thanks to the user interface.
The user interface is a multi-lingual 7 "colors touchscreen. Access
is protected at several levels by passwords.
The SFX+V2 has a native RS485 Modbus communication in
order to communicate with the outside (ex: supervision).
It can be adapted to multiple fieldbuses thanks to a gateway also
integrated in the SFX+V2 cabinet.
The SFX+V2, depending of the filter configuration, is composed
of a master box/cabinet and several slave boxes. A configuration in
form of a bus allows, especially, to reduce the wiring compared to a
conventional configuration. In fact, the slave boxes can be placed
near the declogging solenoid valves while collecting the information
necessary for proper declogging (compressed air pressures, cell
position) and by controlling the cell and tank isolation.
For each SFX+V2, an electrical diagram is associated. Refer to it
for connections and dimensions.
Depending on the filter configuration, some parts of this manual
are not used.

CENTRAL UNIT BOARD :
This board is located in the master box/cabinet. It is the heart of the SFX+V2 system.
It contains all the filter configuration as well as its settings.
It constantly communicates with the slave boxes and the HMI screen.
It processes the exchanges coming from the Modbus RTU client communication.
Depending on the configuration, it can be equipped with a pressure sensor for measuring the load loss pressure,
4-20mA analog input and output, several digital inputs and relay outputs.
Note: a kit exists to backup or restore the SFX+V2 settings to or from a disk file. This kit, consisting of a USB cord
and PC software, connects to this card. See the associated documentation (FI72.05666)

SLAVE BOARD :
This board is located in the slave box.
Depending on the configuration, it can be equipped with a pressure sensor for measuring the compressed air in a
tank with the possibility of a 4-20mA output for measure transfer.
It can be equipped with digital inputs and outputs to control the isolation of a tank or the isolation of a cell with
position control.
It manages the activation of a maximum of 18 SV while controlling the electrical and compressed air consumption.
A digital input (for dry contact) is provided on this board in order to make locally, on the concerned slave, a
sequential activation of its SV outputs: at each pulse, a shot is made followed by a pause time. If the input remains
closed (= 1), then the shots follow. Be carreful: these forced locally activation are made independently of the
controls and automation which are managed by the master box/cabinet.
Several slave boxes are used in an SFX+V2.
Each box is identified on the bus by a unique number.
This identifier determines the role of the box in the configuration of the filter (→see associated electrical diagram of
the SFX+V2). To set this number, the card has a rotary switch and microswitches in order to perform the coding:
the number is formed by the position of the rotary switch (0 à 9)
and by adding 10 if SW1 put ON
20 if SW2 put ON
40 if SW3 put ON
Note: the number can therefore
vary from 1 to 79.
Digital input: forcing activation
of SV output.

Sequencer / filter configuration (4/4) :
From this page, it is possible to name the solenoid valves constituting the filter.
For this part, it is considered that the name of a solenoid valve consists of:
•A prefix identical to all solenoid valves of the same cell
•Followed by a solenoid valve number. Number incremented by 1 for the next one
It is therefore just necessary to record the name of the 1st solenoid valves of each cell.
The following solenoid valves are renamed automatically.
For all other names, it will be necessary to provide it during the project study.
These names then appear in the CYCLE page, page where it is possible to view the progress of the
declogging cycle.
Naming only possible at manufacturer level.
