6.2.6 – Auto Manual
When
Aqua Ionic
is programmed in the Auto Volume + Manual mode (this condition must be
confirmed by the illumination of both LEDs on the panel), the regeneration can be activated only
using the
Manual Regen
key on the panel. When the volume exhausts, the
Alarm
output on the
DIN 360° socket activates (but the corresponding LED on the panel does not illuminate). In this
mode, too, the timer performs its checks on the probe reading. At the same moment when the
conductivity value read by the probe exceeds the programmed set point value and remains above
that threshold for the whole time which has been set, the alarm will activate (
Alarm
LED on the
panel and output signal on the DIN 360° socket).
6.3 – Checking the regeneration efficiency
Pin 3 of the DIN 270° socket, if connected to the ground, enables the regeneration quality check
which is performed during the last cycle phase.
Whichever the operating mode and the cause for the regeneration starting, during the last cycle
phase a comparison between the conductivity value read by the probe and the programmed set point
value occurs; when such a check begins, the
Int. Alarm
LED illuminates on the panel.
If the value read by the probe is lower than the set point value, the last cycle phase is terminated
before the expiration of the set time, in order not to waste water. The
Int. Alarm
LED goes out and
the controller will immediately start working.
If, on the contrary, the value read by the probe remains above the set point value for the whole
duration of the last phase of the regeneration cycle, the
Int. Alarm
LED remains on and blocks the
automatic performance of the successive regeneration cycles, since it is evident that there are
problems preventing a correct regeneration performance. Only at this moment the
Alarm
output on
the DIN 360° socket is also activated.
It is possible to press the
Reset
or the
Manual Regen
keys to reset the alarm.
The Reset key allows to restore the correct performance of the regeneration cycles with automatic
start (which will stop again if the cause preventing the performance of a correct regeneration is not
identified and removed in the meantime), while the Manual Regen key allows to immediately
perform a new regeneration (which will end again with an alarm if, as just mentioned, the cause of
the previous alarm is not removed).
NOTE:
In order for this check to be carried out, a duration of at least 1 minute must be
compulsorily programmed for the last phase of the regeneration cycle,
