the same time and are regenerated in
sequence.
To set the volume, press the Volume set
key and proceed as follows:
Volume setting (Tab. 4)
- 1 VOLUME SET =
0 2 0 0 Volume.
The digits on the right-hand side blink.
- 2 ADVANCE = 0 2 0 1 Setting.
- 3 VOLUME SET = 0 2 0 1 Volume. The
digits on the left-hand side blink.
- 4 ADVANCE = 0 3 0 1 Setting.
- 5 VOLUME SET = 0 2 0 0 Volume storage.
The display shows the value as before
the changes.
The volume set following the procedure
of tab. 4 does not become active at the
end of the programming.
It becomes active only by pressing the
Reset key or after a regeneration process.
Thus, after setting the volume (step 5 of
Tab. 4), the display shows the residual
volume and not the volume just set.
To set the divider of the counter, press
the Meter divider key and proceed as
follows:
Divider setting (Tab. 5)
- 1 METER DIV. =
A A 0 1 Divider. The value
blinks.
- 2 ADVANCE = A A 0 2 Setting operation.
- 3 METER DIV. = 0 2 0 0 Divider storage.
The display shows the new value.
Any time you press Reset while executing
the procedures of tables 3, 4 and 5, you
will exit the programming procedures
without saving the changes.
The Hidden key allows to set the edited
value to zero.
NOTE: The values shown in the column
Display of tables 3, 4 and 5 are only
examples.
The controller can display values
completely different from those indicated
here.
4.4 – Special systems
The full version of Aqua Cubic (with 3 DIN
plugs, see fig. 9) allows you to control
systems with SIATA valves and diaphragm
valves, or systems with diaphragm valves
on specific request.
4.5 – Normal operations
Aqua Cubic, as well as the other SIATA
controllers, is considered “on duty” when
it is able to accomplish a regeneration.
This is possible ONLY when the controller
“senses” that the cam is correctly
positioned at the limit stop. To perform
some tests before installation, Aqua
Cubic must be connected to its case, so
that the limit switch be correctly closed.
Aqua Cubic does not allow any
operation until the limit switch input is
closed. As already indicated in 4.3, after
programming Aqua Cubic press the
Reset key or perform a regeneration
process in order to transfer the new
parameters into the memory.
4.6 – Managing the volume
Steps of tab. 4 show how to program the
treatable volume. If you use the Hall
effect-based, SIATA liter counter, then set
the divider (AA01, tab. 5) to 14, that is,
every 14 impulses the available volume
is decreased by an average, non
settable amount of one liter.
Thus the maximum programmable
volume is 10.000 liters. If you need to use
a larger volume, then use a simple
arithmetical operation by multiplying the
divider by two, three, four and so on.
At the same time, divide the treatable
volume by two, three, four and so on.
For example:
• 15.000 liters of water must be treated:
- Volume/2 = 15.000/2 = 7500 in steps 1
and 3 of tab. 4
- Divider x 2 = AA14 x 2 = AA28 in step 2
of tab. 5
When the device begins working, the
treatable volume will be 7500 liters.
• 50.000 liters of water must be treated.
- Volume/5 = 50.000/5 = 0000 in steps 1
and 3 of tab. 4
- Divider x 5 = AA14 x 5 = AA70 in step 2
of tab. 5.
When the device begins working, the
treatable volume will be 10000 liters
(displayed as 0000).
Please note that Setting the volume to
0000 means setting it to 10.000. Setting
the divider to AA00, means setting it to
100. The maximum treatable volume
when using the Hall effect-based, SIATA
liter counter is 70.000 liters, obtained by
setting the treatable volume to 10.000
liters and the divider to AA98. If you use
a counter issuing one impulse each liter
(or cubic meter), the maximum treatable
volume is 1.000.000 of liters (or cubic
meters). To do so set the treatable volume
to 10.000 liters and the divider to AA00
(this corresponds to 100 impulses each
liter or cubic meter). Please note that,
given the nature of the Reed counters,
the usage of counters type 1 impulse/1
m3 or similar is discouraged.
4.7 – Reset
Several events may influence the
controller: battery exhausted, very high
electromagnetic disturbance (beyond
the limits established by the EN 50082-1
standard), handling the electronic board,
a short circuit between connections or
DIN sockets.
Such events may cause one of the
following problems: the “out of program”
and the “latch up”. In the first case, the
RAM on the CPU becomes “dirty” due to
the disturbing event. The results are
unpredictable: for example, complete
failure of the controller, abnormal
behavior, or the alteration of working
parameters.
The second case happens when the CPU
autonomously turns its state to “latch-
up”, a special condition that allows it to
be protected against potential damages.
The difference consists in the fact that
the first condition is mostly autonomously
solved by the controller thanks to an
autoreset circuit that becomes active
when it is not receiving any signal from
the micro-controller for at least 5 seconds
of anomalous microcontroller signals. The
second condition always requires a
manual intervention.
Figures 5 and 6 show where it is necessary
to intervene in order to solve the above
mentioned conditions. The first operation
to be performed when the controller is
apparently off, or when its behavior is
anomalous, is the so called “software
reset”.
It consists in short-circuiting for a while
points A1 and A2 shown in fig. 6, when
the controller supply transformer is
connected to the supply voltage.
If this operation gives no results, proceed
with the second reset type: the “hardware
reset”.
It consists in short-circuiting for 5 seconds
points B1 and B2 shown in fig. 6, when
the controller supply transformer is
disconnected from the supply voltage.
Once this operation is completed,
connect the supply transformer to the
supply voltage and check that the
controller powers on immediately or after
the 5 seconds necessary for the autoreset.
If the controller does not power on, repeat
the “software reset ” on points A1 and
A2 shown in fig. 6. If the controller still
remains off, please refer to Chap. 5.
Figures 5 and 6 show the points involved
in the reset procedure.
4.8 – Connections
Through the 180º DIN socket, shown in fig.
7, Aqua Cubic can be connected to
some external devices as follows:
• Contacts 1 – 3 = Volume, reed counter
or with closing not powered.
• Contacts 1 – 5 – 3 = Volume, magnetic
counter to Hall effect powered by the
t12 Vdc.
• Contacts 1 – 4 = Input of the signal of
inhibition (in closing).
• Contacts 2 – 5 = Output of the signal
Limit cycle impulse in Open Collector
mode.
Fig. 8 shows the correct usage of Cycle
End Impulse, available as Open Collector.
The relays should not exceed a maximum
coil activation current of 20mA.
Below are the codes of some relays that
can be used for this purpose.
They all have a coil voltage of . Builder
