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. Results are unpredictable: for
example, complete failure of the
controller, abnormal behavior, or the
alteration of working param
The second case happens when the CPU
autonomously tur ns 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 (from 9/98 version only);
in the second case a manual intervention
is always necessary.
Figures 10 and 11 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 point A1 and
A2 shown in fig. 11 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
point B1 and B2 shown in fig. 11 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 the
points A1 and A2 shown in fig. 11.
If the controller still remains off, please
refer to Chapter 5.
Figures 10 and 11 show the points
involved in the reset procedure.
and 7 of tab. 3.
• At step 9 of tab. 3, press Advance in
order to turn both Time and Volume led
on.
• Exit the programming mode then press
Time/Volume to switch the displayed
value from clock to volume.
• Press Reset. The display should indicate
the programmed value, that is, 0002.
• Using a magnetic sensor cable and a
SIATA turbine, decrease the volume down
to 0.
• Press Time/Volume to switch the
displayed value from volume to clock.
• Set the clock to 23.59 then wait until
the clock turns to midnight.
• After the clock has turned to midnight,
the regenerating process should start.
NOTE: To perform these tests, the limit
micro-switch of the controller must be
correctly connected and operative. For
this reason we recommend to use the
controller when mounted in its case.
4.11 – Diagnostics
Aqua Clor has a diagnostic system, that
the maintenance personnel can use to
learn the status of the controller. To
access this function, press and hold the
Advance key for at least 5-6 seconds.
The following parameters will be
displayed:
- 0 2.3 0 = Regenerating process time.
- F – 0 0 = Days elapsed since the last
regenerating process.
- 0.0.0.0. = Number of regenerating
processes performed.
- 0 0 0 0 = Volume consumed since the
last regenerating process. The counter
counting the performed regeneration
processes cannot be reset by the user.
5 – TROUBLESHOOTING
Here follow some basic troubleshooting
operations to solve those small problems
that can arise while using Aqua Clor.
As a general rule it is suggested,
whenever possible, to check the problem
by replacing the sole electronic board
with another one, new or certainly
working. It is important to understand
whether the problem comes from
electronics, mechanics, or the wiring
harness. Replacing the electronic board
may be a precious help to identify the
real cause of the defect. If our
suggestions are not sufficient to solve
your problems, please contact the SIATA
assistance department.
The Controller does not power on.
• Outlet out of order. Transformer plug
out of order. Transformer out of order.
Check the problem by connecting any
other device to the same outlet, and by
connecting the controller to another
outlet.
• Wiring harness problems. Open the
case.
Check that the wires are correctly
mounted in the 7-pole connectors.
• The controller is blocked. If you use the
DIN lateral socket, verify that inside the
connector there are no short-circuited
terminals. Follow the instructions in 4.9.
4.9 – Connections
Through the 180º DIN socket, shown in fig.
12, Aqua Clor can be connected to some
external devices as follows:
•
Contacts 1 – 3 = Volume, reed counters
or counters with make, not supplied.
• Contacts 1 – 5 – 3 = supply. 1 – 4 Inhibit
signal input (when closed).
•
Contacts 2 – 5 = Cycle End Impulse
output, Open Collector.
Fig. 13 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 12 VDC.
Models:
• OMRON G5V-1 12Vdc
• TAKAMISAWA MZ-12HS-U
•MATSUSHITA JQ1-12V or JQ1a-12V or
HD1-M-DC12V.
4.10 – Testing the regeneration automatic
start
ion, proceed as follows:
- Case 1: time-controlled regenerating
process autostart.
• Set 0000 as regenerating process time
at steps 1 ad 2 of tab. 3
• Set F-01 as interval in days between two
regenerating processes at steps of tab.

• At step 9 of tab. 3, press Advance in
order to turn the Time LED on.
• Exit the programming mode, then press
Reset.
• Set the clock to 23.59 then wait until
the clock turns to midnight.
• After the clock has turned to midnight,
the regenerating process should start.
Case 2: volume-controlled regenerating
process autostart.
• Set 0002 as treatable volume at steps
4 and 5 of tab. 3.
• Set 0000 as reserve value at steps 6 and
7 of tab. 3.
• At step 9 of tab. 3, press Advance in
order to turn the Volume led on.
• Exit the programming mode, and then
press Time/Volume to switch the displayed
value from clock to volume.
• Press Reset. The display should indicate
the programmed value, that is, 0002.
• Using a magnetic sensor cable and a
SIATA turbine, decrease the volume down
to 0.
• After the volume has reached 0, the
regenerating process should start. Case

a u t o s t a r t w i t h d e l a y e d v o l u m e .
• Set 0000 as regenerating process time
