1 – G E N E R A L C H A R A C T E R I S T I C S
Aqua Ionic manages SIATA multi-way
valves for the creation of water treatment
devices. The regenerative cycle, which
is completely programmable, can be
activated in either of the following ways:
- after a programmable time during which
the probe detects that the water is not
good;
- immediately when the treatable volume
is exhausted;
- manually, using the Manual Regen key;
- immediately by means of the Remote
Start external signal.
Aqua Ionic is provided with an eeprom
memory where the programming is
stored, and of a buffer battery allowing
to keep the working parameters in the
memory in the event of a supply voltage
failure. Aqua Ionic, as well as all the other
SIATA controllers, is compliant with the
EEC Directives and is built in the SIATA
factory in Montespertoli, Florence (Italy)
working with the Quality System certified
according to the following standard ISO
9001 / UNI EN ISO 9001.
2 – MEANING OF LEDs AND KEYS
LED functionality (Tab. 1)
- SET POINT (yellow case) =
It is on during
the set point value setting.
- SET POINT (blue case) = It is on when
the conductivity value surpasses the set
point value.
- ALARM (blue case)
- SET POINT DELAY (yellow case) =
It goes
on during programming when setting the
set point intervention time.During
operation, it illuminates to indicate an
alarm condition.
- EXT. ALARM = It is on when the inhibition
signal is present.
- AUTO SET POINT = It is on when the
regeneration must start because water
is not good.
- AUTO VOLUME = It is on when the
regeneration must start because of
exhausted volume.
- MANUAL = It is on when the regeneration
must not start automatically.
- INT. ALARM = It is on when regeneration
is not successful.
Key functionality (Tab. 2)
- X 0.1 =
When pressed during operation,
it changes the setting of the X 1 or X 10
probes. When pressed at the end of the
programming phase, it allows to access
the programming of the regeneration
cycle phases.
- PROGRAM MODE = It allows to access
the programming functions of the working
parameters.
- ADVANCE = When pressed during
programming or time setting, it allows to
increase the digit blinking on the display.
When pressed during operation, it allows
to display the residual volume.
- SELECT = It allows to change the
regeneration start mode.
- MAN. REGEN = It allows to activate the
regeneration manually.
- RESET = During programming, it allows
to quit without saving the parameter
being modified when the key is pressed.
During regeneration it ends it.
- HIDDEN KEY = Placed below the 6 keys,
in the middle between Advance and
Volume/Clock, it allows to start a test
regeneration. When pressed during some
programming phases, it zeroes the digit
blinking on the display.
3 - GENERAL INFORMATION
Please find herewith below some
instructions to be followed during the
controller usage and maintenance in
order to ensure its long-term operativity.
3.1 – Packaging and storage
The package consists in a box with a
product identification label. The device
must be stored in environments compliant
with the following characteristics: -
temperature 4°C e +40°C; -
relative humidity within 30 % and 95 %.
3.2 – Installation
The controller installation must be
performed by qualified technical staff;
the installation procedures must be
performed when the device is off power.
The device consists in an ABS case closed
on front by a cover blocked with 4 screws.
As an optional, a transparent cover is
available that can be used as a keyboard
protection. The controller is supplied by
a 230 / 12 Vac transformer. Upon request,
other types of transformer are available
(Es. 115 / 12 Vac – 60 Hz). The right hand
side of the case is opened where the DIN
sockets are placed (Fig. 9).
In the event you would like to supply the
controller external drivers (see Fig. 3 and
4) with compressed air, please make sure
that:
• The air pressure be within 1 and 6 bar,
and however not higher than the input
water pressure;
• an air humidification system (with water
or proper silicone lubricant) is mounted
on the air line, in order to prevent the
driver internal seals from getting dry;
SIATA always recommends to supply the
drivers with water.
In this case it is necessary to use an input
filter to avoid impurities. Please be
particularly careful when installing the
controller in environments that are not
compliant with the EN 50082-1 standard
( e l e c t ro m a g n e t i c c o m p a t i b i l i t y ) .
3.3 – Maintenance
Mind to check the battery efficiency
about every 12 months as follows:
• Switch off the timer for at least 15
minutes.
• The timer disconnected from the supply
voltage, check the battery voltage using
a multimeter. If the measured voltage is
less than 3,2 Vdc, replace the battery
with the spare part code 867.
The following servicing operations must
always be performed when the controller
is off power. In case of replacement of
the electronic board only and each time
you operate on the open case, please
avoid as much as possible touching the
components and the welded parts with
y o u r h a n d s , a b o v e a l l i n t h e
microprocessor area, since possible
electrostatic discharges could seriously
damage the controller. Furthermore, we
recommend not to place the electronic
board on a metal surface, unless it is
properly isolated (a couple of paper
sheets will be sufficient). To store the
electronic boards, please always use the
anti-static envelopes that come with the
replacement kits.
Avoid the electronic board to come in
contact with liquids. In case it happens,
please dry it with an air jet.
3.4 – Safety devices
The controller is provided with the
following safety devices :
• Safety and isolation transformer.
• Safety electronic circuit against voltage
peaks and disturbances.
4 – INSTRUCTIONS FOR USE
4.1 – Powering on
Aqua Ionic is not provided with power
switches. Powering on is obtained by
connecting the power transformer to the
outlet.
4.2 – Working
After powering on, the display placed on
the front panel will display the
conductivity value read by the probe.
The regeneration starting modalities are
the following:
- Auto Set Point = The regeneration starts
at the expiration of the programmed
delay time that begins to be counted
when the conductivity value read by the
probe exceeds the programmed
threshold limit.
- Auto Volume = Immediate start when
the available volume is exhausted.
- Auto Set Point + Auto Volume = The timer
performs both the above mentioned
checks and will activate the regeneration
as soon as either of the two checks will
indicate that the foreseen conditions
have been reached. Manual The
regeneration starts only when pressing
the proper key.
- Auto Set Point + Manual = The timer
performs the checks requested by the
Auto Set point mode, but it is not able to
per for m the regeneration in the
automatic mode.
- Auto Manual = The timer
performs the checks requested by the
Auto Volume mode, but it is not able to
per for m the regeneration in the
automatic mode.
4.2.1 – Auto Set Point
When Aqua Ionic is programmed in the
Auto Set Point mode (this condition must
be confirmed by the illumination of the
corresponding LED on the panel), there
is a comparison between the conductivity
value and the programmed set point
value (steps 1 and 2 in tab. 3). When the
conductivity exceeds the set point value,
the device begins counting the set delay
time (step 6 tab. 3). If the conductivity
value does not decrease before
expiration of the delay time, the
