6.2.3.c – List of codes to be programmed
For the programming and the meaning of the codes see par. 6.3. In this modality, the programming of the following
codes is recommended:
Tab. 15 – Table of the codes recommended in the modality “two alternated single columns, PPP2”
Code Meaning
011
Programming of the value of the capacity of resins exchange
100
Programming of the volume of resin and of the percentage of reserve of the column
A
110
Programming of the litre counter divider (prescaler)
112
Programming of the regeneration cycle ( stop times )
210
Transfer of the parameters programmed for the column
A
on the column
B
010
Programming of the hardness value
220
Initialisation of the system
In the case of use of columns of different dimensions, the recommended programming varies as follows:
Tab. 16 – Table of the codes recommended in the modality “two alternated single columns, PPP2” different
columns
Code Meaning
011
Programming of the value of the capacity of resins exchange
100
Programming of the volume of resin and of the percentage of reserve of the column
A
101
Programming of the volume of resin and of the percentage of reserve of the column
B
110
Programming of the litre counter divider (prescaler)
111
Programming of the regeneration cycle ( stop times ) for the column
B
112
Programming of the regeneration cycle ( stop times ) for the column

Initialisation of the system
Remember that in order to use
Aqua Cubic Multiplex
as described in tab. 16, the flag
1CP
must be programmed to
1.
6.2.4 – PPP4 – One duplex column.
6.2.4.a – Operative characteristics.
In this modality
a single distributor connected to 2 SIATA valves
is used. The distributor is connected to the
terminals of the column A.
This distributor has a special cam, modified so as to divide the 360º of rotation between the two valves; the first 180º
are dedicated to column A, the second to column B. Normally defined as column A is the valve connected to the pilots
1 and 2, those nearest to the distributor, and defined column B is the valve connected to the pilots 3 and 4 ( see also the
connections indicated in the attached page C).
Which of the two columns is active, and therefore which valve is in use, depends only on the position of the cam of the
distributor. The controller cannot know which column is in service. In fact, as will be shown, both the optical and
electrical signals will always communicate that column A is in service.
Suppose the following operations are to be carried out when the distributor has the cam in the stroke end position at the
beginning of the first 180º of rotation, that is so as to have the valve A in service. After having keyed in the code
220
,
the controller will begin with the valve A in service. The signal to the pins 43 – 44 of the terminal board will be active.
The LED
A Service
on the panel will be on. The LED
A
will be on to indicate that the display is visualising the volume
of the column A.
