6.2.4.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. 19 – Table of the codes recommended in the modality “one duplex column, PPP4”
Code Meaning
011
Setting of the value of the capacity of resins exchange
100
Setting of the volume of resin and of the percentage of reserve of the column
A
110
Setting of the litre counter divider (prescaler)
112
Setting of the regeneration cycle ( stop times )
010
Setting of the hardness value
220
Initialisation of the system
It should be pointed out that the two columns
must
be of the same dimensions. It is not possible to change in any way
the two columns, either for the dimensions, or for the regeneration cycle.
6.2.5 – PPPA – Two single columns in parallel
6.2.5.a – Operative characteristics.
In this modality there are
two distributors, each of which is connected to a SIATA valve. Both of the columns are
in service.
. It is not possible to have both of the columns in regeneration.
After having keyed in the code
220
, both of the columns are put into service. The signals to the pins 43 – 44 and 45 – 46
of the terminal board will be active. Both of the LEDs
A Service
and
B 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.
With the key
2/+
it is possible to change the column visualised on the display. Each time the key is pressed, LEDs
A
or
B
will come on when the data of the relative column is transferred to the display. If the column visualised is in service it
will be possible to read the residual volume. If it is in regeneration it will be possible to follow the progression.
The two columns cannot regenerate at the same time. If one column finishes its volume while the other is regenerating,
it will simply go into, disactivating the signal of service active on the terminal board, while waiting for the other column
to terminate the regeneration. As soon as this condition has been reached, the column which has just finished the cycle
will enter into service, while the column waiting will begin its regeneration.
This operative modality is not programmable. As shown in tab. 20, any programming of the flags always brings on the
same result.
When one column finishes the available volume, the controller enters immediately into in regeneration. There is no
control on the remote start.
