6.9 – Management of the alarm of end of regenerative autonomy
The installer sizing and putting together the system knows the dimensions of the canisters, how much resin will be
contained in them and how much salt will be consumed for each regeneration. Knowing how much salt to put into the
system he can therefore know more or less how many regenerations are possible with the salt introduced.
Aqua Timer Plus
allows the possibility to programme this value and to decrease it at each regeneration in order to be
able to provide a general indication of how many regenerations are still possible before the salt runs out.
This functionality will be activated via the flag
3CL
which must be programmed with the value
1
.
Once this programming has been carried out, calling up the programming code
SC02
, after having programmed the
time of regeneration and the interval days, it is possible to programme the number of regenerations which can be carried
out (see par. 6.3.2) and a number of reserve regenerations.
The functioning is as follows:
Once the programming has been carried out, the key
Reset
must be pressed to activate the values set.
With the key
Advance
the mode of visualisation of the display can be changed so as to see first
d-xx
which is the value
of reserve set, then
ddxx
which is the residual number of regenerations which can be carried out.
As soon as the residual number of regenerations which can be carried out (
ddxx
) is equal to the programmed number of
reserve regenerations (
d-xx
), the led
SALT
comes on on the panel of
Aqua Timer Plus
to indicate that the above
situation has been reached. Starting from this moment, and in any case before the number of reserve regenerations has
run out, the operator must be sure to introduce salt into the system ( of a quantity which will take the level back to its
original ) and press the key
Reset
to reset the counters and turn off the led
SALT
.
When the number of regenerations which can be carried out reaches the value
dd00
, one last regeneration is available,
after which
Aqua Timer Plus
is blocked with the leds
SALT
and
ALARM
which come on and the letters
–SAL
lit
solidly on the display.
At this point the operator must intervene, introducing more salt and pressing the key
Reset
.
Obviously, if the key
Reset
is pressed without having introduced more salt to the system,
Aqua Timer Plus
will carry
out the regenerations of the system, without salt.
6.10 – Putting into service
IMPORTANT
Remember always to key in the code
SC00
(ref. par. 6.3) after the various phases of programming before
Aqua Timer
Plus
is put into service.
Always remember that before it is possible to carry out operations on the keypad of
Aqua Timer Plus
, it must be
checked that the cam of the distributor is in the
stroke end
position (except when it is in regeneration, a condition
which can be checked by using the key
Advance
putting the display into the visualisation mode of the regeneration -
see par. 4). If it is intended to programme
Aqua Timer Plus
before its installation, that is without the distributor
connected, the limit switch entry must be closed with a connector bridge.
During the normal functioning of
Aqua Timer Plus
, the leds
A
or
B
will be on to indicate which column is in service.
During the service, the impulses coming from the litre counter sensor, as well as decreasing the volume available
through the litre counter divider set with the programming code
SC04,
also acts on the counter of the
dosing pump
programmed with the programming code
SC05
(See par. 6.3.2). The value set represents the number of impulses which
must be read by the
controller
to have an impulse at the dosing pump. The duration of this impulse cannot be modified.
With the programming code
SC05
the duration of the
end of cycle impulse
is also modified. This time starts as soon as
the stop time of the last phase of the regeneration cycle ends, and the motor starts to move to take the cam of the
distributor into the stroke end position.
