6.11 –Modifying the programming during service, the flag 2CP
As already explained in par. 6.3,
Aqua Cubic Multiplex
calculates the volume of water which can be treated using the
values of hardness of the water, the capacity of ionic exchange of the resins and the quantity of resin used. The
calculation is carried out automatically at the end of the programming of the hardness (code
010
), or otherwise may also
be carried out keying in the code
211
.
When these calculations are carried out at the time of the installation, the value of volume calculated must become
operative immediately, so as to be able to start up the system.
When, however, the value of hardness is modified during the service, the fact of having the new value of volume
operative immediately can become extremely dangerous, in that it cancels the value of residual volume treatable by the
system; the consequence is that the column runs out and the regeneration does not start because the controller thinks it
has a column which is still working efficiently.
The solution is the use of the flag
2CP
, which tells the controller when to make the value of volume calculated
operative.
If it is programmed with the value
0
, the modifications to the programming are immediately operative.
When it is programmed with the value
1
the modifications are operative only after the next regeneration.
It can be a good rule to programme the flag
2CP
with the value
1
at the end of the installation, so that any modifications
to the parameters during the service of
Aqua Cubic Multiplex
do not upset the possibility of the system to operate.
7 – What to do if …
Some basic operations for the resolution of small problems which may arise during the use of
Aqua Cubic Multiplex
are described below.
If the suggestions shown do not help to resolve the situation, please call the SIATA service assistance.
7.1 - ... Aqua Cubic Multiplex does not come on ?
1. Check that the plug is correctly inserted in the electricity socket;
2. Check that the socket is correctly supplied;
3. Check that the adapter used does actually supply 24 Vac, code AC-PLUS 1/05, check that the transformer used
does actually supply 24 Vac;
4. Check that the current conductors are corrected inserted into the terminals and that these are closed correctly.
5. Check that the fuse positioned on the panel has not blown.
In the case of Aqua Cubic Multiplex at 230 Vac, AC-PLUS2/05, this fuse must be of delayed 0.5A;
In the case of Aqua Cubic Multiplex at 24 Vac, AC-PLUS1/05, this fuse must be of delayed 1A
7.2 - ... the motors of the distributors do not stop ?
1. Check that the run end wires of the distributors, marked 96-S, are correctly inserted in the terminals and that these
are closed correctly;
7.3 - ... there is no current to the utilisers?
1. Remember
that
Aqua Cubic Multiplex
does not supply current to the exits,
but only closures that the operator
must wire at his own discretion, check that the wiring is correct, that the conductors are correctly inserted into the
terminals and that these are closed correctly;
