1- By interval of working time of the installation.
2- By differential of pressure.
3- By external or remote signal.
4- Manually.
A backflushing cycle will be activated each time the programming time passes.
A backflushing cycle will be activated each time there is a differential of
pressure in the equipment equal or higher than the regulated in the
Differential Pressure Gauge, and after the confirmation time of the pressure
gauge programmed in the FBC.
A backflush will be activated when sending a contact free of tension to the corresponding input
of the FBC trough an external or remote signal.
OK
2.4 Types of activation and backflushing cycles.
You can activate a backflushing cycle manually, through the
keyboard of your Control Unit. The backflush will be activated when
you keep pressed for some seconds the key OK.
AZUD FBC Control Unit will allow to keep all this options at the same time, or select just some of
them.

Working Description:
• The start of the sequential self-cleaning process is made when the Control Unit activates the
backflushing cycle under one of the four possible orders: existing differential of pressure, attending to
the frequency of irrigation, by direct actuation on the keyboard or by external signal.
The programmer which integrates the Control Unit, activates the electric contact which supplies
voltage to the NC solenoid, in charge of activating the first station that makes the self-cleaning
process; transforming the electric signal in a hydraulic signal in charge of feeding the chamber of the
3-ways valve.
Through the feeding of the chamber of the 3-ways valve it is made a movement of the internal piston
which closes the entrance of water to the filter and communicates the interior of the filter with the
drainage manifold. This allows the filtered water from the rest of filter from the outlet manifold,
introduces to the filter in the opposite way from the filtration direction, activating the self-cleaning
mechanism of DF-DISC filtration discs.
The deactivation of the solenoid from station n.1 allows the 3-ways valve come back to the resting
position and the filter to the filtration process.
Once the station n.1 has finished the backflushing process, this is repeated sequentially until finishing
all the stations in the filtration equipment.
The end of the self-cleaning process coincides with the closure of the drainage outlet and the opening
of the inlet to the filter from the inlet manifold, being re-established the initial filtration conditions.
2.5.- Working Description.
AZUD FBC Control Unit integrates all the control, detection and operation elements that allow AZUD
HELIX AUTOMATIC filtration equipment to have complete autonomy. All the components are supplied
already assembled, with the auxiliary elements that complete the electric and hydraulic system, which
turn the Control Unit into an autonomous and automatic system.
The electronic control system and the electric auxiliary elements are placed in a water-tightness housing,
completely isolated from the hydraulic components.

Following the different parameters to be programmed of your Control Unit will be introduced. AZUD FBC
incorporates a standard programming which allow the user to start up the filtration equipment by the first
time and being familiar with the programming to be adapted to the particular conditions of your
installation.
Anticipation time of the signal of the sustaining electrovalve, which allows this to reach its regulation of
pressure before starting the backflushing cycle.
If your equipment does not have this option press time 0 sec.
3.2 Anticipation time of the sustaining valve.
Time that remains active each one of the filtration stations which made the filtration system. The
programmed time is the same for all the stations. During one cycle of activations it is made sequentially
one activation for each station the system has programmed.
3.3 Backflushing time of each one of the stations.
Time that passes from the stop of the actuation of one filtration station and the start on the activation of the
following.
During this time the system deactivates all the outlets active (general outlet).
3.4 Time between stations.
3.5 Time between backflushing stages.
Minimal frequency to make the activation of a backflushing cycle, always the system in active filtration
process.
3.7 Delay of the differential pressure gauge.
It is defined as the necessary time in which the contact must be closed in a continuous way in the
corresponding inlet of the differential pressure gauge for one activation order to be effective and the
backflushing cycle is activated. This is a performance especially indicated to avoid unnecessary
backflushings provoked by the start of the filling of the installation. (Start-up of the installation).
Select the number of stations of your filtration equipment.
3.8 Number of Stations of the Filtration Equipment
3.6 Deposit filled time
Select the filling time of the auxiliary tank (always in SECONDS). The minimum and maximum time
interval that can be programmed is 20-150 sec respectively

The differential pressure you should regulate in your differential pressure gauge should be between 0,2
– 0,3 bar over the pressure with the maximum flow of your system, when the filters are clean.
1- AZUD Differential pressure gauge adjustment.
Regulate the differential pressure gauge according to the model.
3.8 Adjustment of the different types of differential pressure gauges.
Azud FBC Control Units include a differential pressure gauge which indicates the differential pressure
existing in the installation and provides us with a free-tension contact once the pre-established
differential pressure is exceeded. The differential pressure reading is carried out through two P1 and P2
inlets (see hydraulic linkages), which are collected in the inlet and outlet manifold respectively.
The differential pressure value in an equipment's inlet and outlet is not the same in all the installations.
So you must regulate the differential pressure value which will activate a backflushing cycle in the
equipment. The Control Unit has been calibrated at 0.6 Bar by the factory. You must regulate this value
according to the installation conditions.
The differential pressure gauge is provided with a regulator device to movethe
small hand, modifying the maximum value of the pressure difference.
EXAMPLE
ARECENTLY INSTALLED SYSTEM which working with a MAXIMUM FLOW, has a 0,1 bar
DIFFERENCE of pressure .
The recommended value is 0,3 - 0,4 bar.

This option can be used to the installation of a Pressure Sustaining Valve.
AZUD HELIX AUTOMATIC Equipment needs to guarantee a minimal pressure during the backflushing
of the stations. If your installation does not fulfil this requirement, AZUD can supply an adequate
Sustaining Valve to your installation.
