The “Alarm/Alarme” Diode is Lit.
In operating phase
• Outside range (more pH 8 – red indicator lamp “8” lit): the system picks up a pH value above
the pH reading range of the appliance.
• Outside range (less than pH 6.2 – red indicator lamp “6.2” lit): the system picks up a pH value
below the pH reading range of the appliance.
In calibration phase
The characteristics of the sensor are outside the calibration range, the pH 4 diode is lit and the
“Alarm/Alarme” diode is flashing.
The “Hold/Pause” Diode is Lit.
This indicator lamp indicates that the dosing pump is not going to start. It is either when you are
in calibration phase or when the pool filtration is paused.
Note: The unit includes an optional safety against over-dosage of corrective product, in order to avoid any
excessive injection in case the required pH is not reached after 3 cycles of dosage.
Operating Principle (if activated):
1st alarm: the “Alarm/Alarme” diode flashes after 3 cycles of dosage. The pH Perfect is still operating.
2nd alarm: the “Alarm/Alarme” diode flashes and the “Hold/Pause” diode is lit; the pH Perfect stops
dosing. This second alarm is activated after the 4th closing cycle. Just press the “Read SET” key to
come back to normal operation.
