3.3 – Maintenance
Please mind to check the battery
efficiency about every 12 months as
follows:
• Switch off the timer for about 15
minutes.
• Switch on the timer and check the time
indicated on the display. If the time
displayed is midnight (00.00), it is
necessary to replace the battery with
the spare part code 867. The following
servicing operations must always be
performed when the controller is off
power. When replacing the sole
electronic board, and each time you
must operate with the case opened,
avoid as much as possible touching
components and welded parts with your
hands, especially near the CPU, since
electrostatic discharges could eventually
damage the controller. Furthermore, we
recommend not to place the electronic
board on a metal surface, unless it is
properly insulated (a few paper sheets
will be sufficient). To store electronic
boards, please always use the anti-static
e n v e l o p e s t h a t c o m e w i t h t h e
replacement kits. Avoid the electronic
board to come in contact with liquids. In
case it happens, please dry it with an air
spray.
3.4 – Safety devices
The controller is provided with the
following safety devices :
• Safety and insulation transformer.
• Safety electronic circuit against voltage
peaks and disturbances.
• Autoreset (par. 4.9) – Available from
version 9/98
4 – INSTRUCTIONS FOR USE
4.1 – Powering on
XP Controller 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 located
on the front panel displays the timer. If
the battery needs replacement, the time
will display midnight (00.00), otherwise
an updated time. When powering on for
the first time, it is advisable not to switch
off the controller for at least 24 hours on
end, in order to avoid an anomalous
battery charge. The regeneration starting
modalities are the following: Time Start
at the programmed time after the preset
interval days have elapsed. Mixed Start
at the programmed time without waiting
for the interval days when the treatable
volume is exhausted. (This modality is
available in the volumetric version only).
4.3 – Programming
XP Controller is programmed using the
hidden key, and the values can be
modified using the Advance key.
Proceed as follows to program :
Programming table (Tab. 2)
- 1 HIDDEN KEY =
0.2 3 0 Regeneration
starting time. The minutes flash.
- 2 HIDDEN =
KEY 0.2 3 0 Regeneration
starting time. The hours flash.
- 3 HIDDEN KEY =
F F 0 7 The interval in
days between two regeneration
processes. (from 1 to 14 days)
- 4 HIDDEN KEY =
2 0 0.0 The treatable
volume. The digits on the right-hand side
flash.
- 5 HIDDEN KEY =
2 0 0.0 The treatable
volume. The digits on the left-hand side
flash.
- 6 HIDDEN KEY =
0 0 0 0. The volume
reserve. The digits on the right-hand side
flash.
- 7 HIDDEN KEY =
0 0 0 0. The volume
reserve. The digits on the left-hand side
flash.
- 8 HIDDEN KEY =
A A 1 4 The volume
program the treatable volume. Using the
SIATA magnetic liter-counter sensor, the
value of the divider (AA14, step 8 in Tab.
2) must be set to 14, which means that
the available volume is reduced by one
liter every 14 impulses issued by the sensor.
In this way the maximum treatable
volume that can be programmed is
10.000 liters. If you need to use a larger
volume, it is possible to do a simple
arithmetical operation, that is to multiply
by two, by three, by four, etc. the divider
and at the same time divide by two, by
three, by four, etc. the treatable volume.
In the event you wish to program a
reserve, it is necessary to divide it as well
as the volume.
Examples:
• 15.000 liters of water must be treated,
to obtain a reserve of 1.000 liters:
- Volume/2 = 15.000/2 = 7500 in steps 4
and 5 in tab. 2
- Reserve/2 = 1.000/2 = 500 in steps 6 and
7 in tab. 2
- Divider x 2 = AA14 x 2 = AA28 in step 8
in tab. 2
• When starting operations the treatable
volume will be 7000 liters (7500 – 500).
50.000 liters of water must be treated, to
obtain a reserve of 1.000 liters:
- Volume/5 = 50.000/5 = 0000 in steps 4
and 5 in tab. 2
- Reserve/5 = 1.000/5 = 200 in steps 6 and
7 in tab. 2
- Divider x 5 = AA14 x 5 = AA70 in step 8
in tab. 2
When starting operations the treatable
volume will be 9800 liters (10000 – 200).
Please note that programming the
volume by setting the 0000 value, means
programming 10.000, while setting the
AA00 value for the divider means
programming the divider as 100. You
can treat maximum 70.000 liters water
with the SIATA magnetic sensor by
programming 10.000 liters for the
treatable volume and AA98 for the
divider (Volume / 7 and divider x 7). If
you use a counter issuing one impulse
every liter (or cubic meter), the maximum
treatable volume will be 1.000.000 liters
(or cubic meters) if you set to 10.000 liters
the treatable volume and to AA00 the
divider (corresponding to 100 impulses
every liter or cubic meter). In case you
are using high flow rate Reed counters,
such as 1imp./1m3, the low rotation
speed of the magnet could cause
spurious impulses that will be calculated
as real impulses.
4.8 – Testing the regeneration automatic
start
To test the regeneration automatic start,
proceed as follows:
- C a s e 1 , X P C o n t ro l l e r i n t h e
Chronometrical version.
• On steps 1 and 2 in tab. 2, set 0000 for
the regeneration time.
• On step 3 in tab. 2, set 1 as the number
of interval days.
• Quit programming and perform a
regeneration process.
• If you are using a 9/98 or later version,
use the Man. Regen. key to exploit the
step-by-step functionality.
• Once the regeneration has terminated,
set the timer to 23.59 and wait for it to
indicate midnight.
• When midnight is displayed on the timer
the regeneration will start.
- Case 2, XP Controller in the Volumetric
counter divider. The digit flashes.
- 9 HIDDEN KEY =
P r - - Value not currently
in use, to be ignored. The digit does not
flash.
- 10 HIDDEN KEY =
P r - - The display is still
indicating the same value.
- 11 TIME OF D. =
F r 5 0 Power Frequency
(50 or 60 Hz.)
- 12 TIME OF D. =
1 C 1 0 Stopping time
for the first regeneration phase.
- 13 HIDDEN KEY =
2 C 3 0 Stopping time
for the second regeneration phase.
- 14 HIDDEN KEY =
3 C 2 0 Stopping time
for the third regeneration phase.
- 15 HIDDEN KEY =
4 C 1 0 Stopping time
for the fourth regeneration phase.
- 16 HIDDEN KEY
= E n d - End of
programming. It quits after 3 seconds.
- 1 2 3 0
The display shows the local time
again.
Pressing the Hidden key instead of the
Time of Day key at step 11 of tab. 2 will
quit programming without accessing the
regenerative cycle phases. The latter is
the recommended procedure. Attention!
If the controller is used in chronometric
regeneration start and the treatable
volume value has been set up to 0 (zero),
every day a regeneration cycle will be
performed.
IMPORTANT !! Changes per formed
according to the tab. 2 steps becomes
operational after the first regeneration
only. Modifying the programming without
immediately performing a regeneration
process will result in a behavior compliant
with the previous programming, not with
the new one.
The local time is set using the Time of Day
key and the values can be modified using
the Advance key. Proceed as follows to
perform programming:
Local time setting (Tab. 3)
- 1 TIME OF DAY =
0 8 0 0 Local time. The
minutes flash.
- 2 TIME OF DAY =
0 8 0 0 Local time. The
hours flash.
- 3 TIME OF DAY =
0 8 0 0 Pressing Time of
Day again confirms changes.
4.4 – Filtration
XP Controller also allows to create filtering
systems by using the proper version of the
SIATA valves. In order for the system to
work correctly, it is necessary to program
time to 0 at steps 12 and 13 of Tab. 2
unless a settling phase is required.
4.5 – Starting operations
XP Controller, as well as all SIATA
controllers, is considered “on service”
when able to accomplish resins
regeneration. This is possible ONLY when
the controller “senses” that the cam is
correctly positioned at the limit stop. In
order to perform a few tests before
installation, it is necessary to connect XP
Controller to its case in order that the limit
switch input be correctly closed. With
reference to what already stated in par.
4.3, once the XP Controller programming
has been modified, it is necessary to
perform a regeneration process in order
to transfer the new parameters into the
memory again.
4.6 – Managing the reserve
The reserve value programmed through
steps 6 and 7 of Tab. 2 is subtracted from
the treatable volume value set through
steps 4 and 5 of Tab. 2. The result will be
the available volume. Once the available
volume is exhausted, a regeneration
process is performed at the scheduled
time. If you program 5000 liters of
treatable volume and 1000 liters of reserve
volume, the calculated available volume
will be of 4000 liters. Available Volume =
Treatable Volume – Reserve
4.7 – Managing the volume
