3.3 – Maintenance
It is a good rule, every 12 months, to carry
out a check on the efficiency of the
battery, as follows:
• Turn off the timer for about 15 minutes.
• Turn the timer back on and check the
time shown on the display. If it reads
midnight (00.00), the battery must be
replaced with the spare part cod. 867.
The following maintenance operations
must always be carried out with the
controller turned off. If the PC board is
to be replace, and any time any
intervention with the box open is
necessary, avoid, as far as possible,
touching the components and the
welding, especially in the area of the
micro-processor, since any electrostatic
d i s c h a r g e s c o u l d c a u s e s e r i o u s
malfunctions of the controller. It is also
advisable to avoid placing the PC board
on a metal surface which has not been
adequately isolated (a few sheets of
paper are adequate protection). For
the storage of the PC boards, always use
the anti-static bags in which the spare
parts kits are delivered. Avoid the PC
board coming into contact with liquids.
If this should happen, dry it with jets of
air.
3.4 – Protection devices
The controller is equipped with the
following protection:
• Isolation and safety transformer.
• Electronic circuit for protection from
voltage peaks and from disturbances
4 – INSTRUCTIONS FOR USE
4.1 – Turning on
Xp Mode is not equipped with supply
switches. It is turned on by connecting
the supply transformer to the electricity
socket.
4.2 – Functioning
After turning on the controller, the display
on the front panel will visualise the clock.
If the battery must be charged, the clock
will show midnight (00.00), otherwise, it
will show another time. When the
controller is turned on for the first time, it
is advisable not to turn it off for at least
24 consecutive hours, in order to avoid
an anomalous charge to the battery.
The starting up modalities of the
regeneration are the following:
• start up at the programmed time, after
the programmed interval days have
passed;
• start up at the programmed time
without waiting for the interval days, when
the available volume has run out. During
the service, using the hidden key, it is
possible to switch the visualisation mode
of the display between the volume and
the clock; the latter may be recognised
by the presence of the luminous dot
flashing at the centre of the display. If it
is not present the display is visualising the
residual volume.
4.3 – Programming
The programming of Xp Mode is carried
out using the key Program Mode, and
the values may be modified with the key
Advance. The programming proceeds
as follows:
Programming table (Tab. 3)
- PROG. MODE =
0.2 3 0 Start time of the
regeneration. The minutes are flashing.
- 2 PROG. MODE =
0.2 3 0 Start time of
the regeneration. The hours are flashing.
- 3 PROG. MODE =
F F.0 7 The interval
days between two regenerations.
- 4 PROG. MODE =
2 0 0.0 The treatable
volume. The digits on the right are flashing.
- 5 PROG. MODE =
2 0 0.0 The treatable
volume. The digits on the left are flashing.
- 6 PROG. MODE =
0 0 0 0. The reserve of
the volume. The digits on the right are
flashing.
until the entry of the limit switch is closed.
As per par. 4.3, once the programming
of Xp Mode has been modified, it is
necessary to press the key Reset or to
carry out a regeneration in order to be
able to memorise the new parameters.
4.6 – Management
of the reserve
The value of the reserve programmed
with the step 6 of tab. 3 is subtracted
from the value of the treatable volume
set with step 4 of tab. 3.
The result is the available volume, the
finishing of which prepares for the
regeneration which will be carried out
immediately if the controller is set to work
in the volume mode, or at the
programmed time if the controller is
programmed to work in the mixed mode.
If 5000 litres of treatable volume are
programmed, with 1000 of reserve, the
calculated volume available is 4000 litres.
When Xp Mode works in the Volume
mode, it is advisable to leave the reserve
programmed with the value 0000, in
order to best use the capacity of the
system. Available Volume = Treatable
Volume – Reserve.
4.7 – Managing the volume
The steps 4 and 5 of tab. 3 show the
programming of the treatable volume.
Using the SIATA Hall effect litre counter,
SIATA, the value of the divider (AA14,
step 8 tab. 3) must be programmed with
the value 14, that is every 14 impulses
from the sensor there is the average non-
adjustable decrease of one litre of
available volume.
In this way, the maximum treatable
volume it is possible to programme is
10,000 litres. If a higher volume is required,
it is possible to use a simple arithmetical
operation, that is to double, triple,
quadruple, etc., the divider and at the
same time to divide by two, three, four,
etc., the treatable volume.
I f a r e s e r v e i s r e q u i r e d t o b e
programmed, this must also be divided
by the volume.
For example:
•15000 litres of water must be treated,
and 1000 of reserve are required:
- Volume/2 = 15.000/2 = 7500 in the steps
4 and 5 of tab. 3
- Reserve/2 = 1.000/2 = 500 in the steps
6 and 7 of tab. 3
- Divider x 2 = AA14 x 2 = AA28 in the
step 8 of tab. 3
• 50,000 litres of water must be treated
and 1000 of reserve are required:
- Volume/5 = 50.000/5 = 0000 in the steps
4 and 5 of tab. 3
- Reserve/5 = 1.000/5 = 200 in the steps
6 and 7 of tab. 3
- Divider x 5 = AA14 x 5 = AA70 in the step
8 of tab. 3 On entering into service the
treatable volume will be 9800 litres (10000
– 200).
Note that programming the volume with
the value 0000, means programming
10,000, programming the divider with the
value AA00, means programming the
divider for 100. The maximum treatable
volume using the SIATA Hall effect litre
counter is 70,000 litres, programming
10,000 litres of treatable volume and
AA98 of divider.
If a counter providing one impulse every
litre (or cubic metre) is used, the
maximum treatable volume is 1,000,000
litres (or cubic metres) programming
10,000 litres of treatable volume and
AA00 of divider (corresponding to 100
impulses every litre or cubic metre).
It should be pointed out that, given the
- 7 PROG. MODE =
0 0 0 0. The reserve of
the volume. The digits on the left are
flashing.
- 8 PROG. MODE =
A A 1 4 The divider of
the volume counter. The digit is flashing.
- 9 PROG. MODE =
A A 0 2 Not used
- 10 PROG. MODE =
A A 0 2 The display
continues to show the selection.
- 11 TIME OF DAY =
1 C 1 0 The stop time
of the first phase of the regeneration
cycle.
- 12 PROG. MODE =
2 C 3 0 The stop time
of the second phase of the regeneration
cycle.
- 13 PROG. MODE =
3 C 2 0 The stop time
of the third phase of the regeneration
cycle.
- 14 PROG. MODE =
4 C 1 0 The stop time
of the fourth phase of the regeneration
cycle.
- 15 PROG. MODE =
4 d 1 0 The
programming is finished. After about 3
seconds, exit.
- 16 =
1 2.3 0 The display visualises the
clock or the volume.
With reference to step 11 of tab. 3, if
instead of pressing the key Time of Day
the key Program Mode, is pressed, the
programming is exited from, without
accessing the programming of the
regeneration cycle times. The latter is the
procedure recommended for the user to
follow. It is possible to press the Reset
key at any time to exit from the
programming, without memorising any
modifications made to the value flashing
on the display.
In correspondence with step 15 of tab.
3, there is the writing of the parameters
programmed in the eeprom .
IMPORTANT !! The programming which is
set according to the steps of tab. 3 does
not become operative immediately. In
order for it to become so, the operator
must press the key Reset or carry out a
regeneration via the key Manual Regen.
If this simple rule is not followed, the
working of the controller will be as for the
old programming and not the new
programming.
The resetting of the clock is carried out
via the key Time of Day, and the values
may be modified with the key Advance.
The programming proceeds as follows:
Resetting of the clock (Tab. 4)
- 1 TIME OF DAY =
0 8 0 0 Clock. The
minutes are flashing.
- 2 TIME OF DAY =
0 8 0 0 Clock. The hours
are flashing.
- 3 TIME OF DAY =
0 8 0 0 Pressing again
Time of Day the modifications are
confirmed.
If Reset is pressed at any time within the
procedure shown in the table, the
resetting of the clock is exited from without
memorising any modifications made
.
4.4 – Filtration
Xp Mode also allows for filtration systems
to be controlled using the relevant version
of the SIATA valves. To obtain the correct
functioning of the system, the time 0 must
be programmed in the steps 12 and 13
of Tab. 3 when the arrangement phase
is not necessary.
4.5 – Putting into service
Xp Mode, like all SIATA controllers SIATA,
is considered to be in service when it is
able to carry out the regeneration.
This is possible ONLY when the controller
“feels” that the cam is correctly positioned
at the stroke end. In order to be able to
carry out trials before installation, Xp
Mode must be connected to its box, in
such a way that the limit switch is correctly
closed.
Xp Mode does not allow any operation
