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.
