When filtration cycles are used (all filtration modes except
end of each filtration cycle. The updated pH is displayed immediately. If only one filtration cycle is set, the pH is measured
automatically once per day; if both filtration timers are set, pH is measured automatically twice per day.
When filtration runs in 24/24
pH can be measured at any time by first stopping the filtration pump, and then selecting
pH information is used for pH control functions and Alerts. However, independent pH control systems can be installed with the
equipment. In this case equipment can be used to measure pH and trigger Alerts if the pH is out of the normal range.
pH Sensor Calibration
The sensor can be calibrated using pH buffer fluids or liquids of known pH.
Information and Guidance
The equipment has proportional- integral pH Control. An ON/OFF feeder pump (peristaltic or electromagnetic) and installation kit is
required. pH Control logic and safety:
With filtration cycles:
The dosing is executed once at the beginning of each filtration. It is recommended to program two daily
•
filtration cycles, to enable two dosing periods per day. Filtration should be stopped at least 30minutes
between 2 filtration cycles to allow pH algorithm to work properly.
Whatever are the settings, maximum dosing time is 30 minutes per filtration cycle (60 minutes per day if the
•
recommendation for two cycles is respected).
In 24/24 filtration mode:
The reading is done every hour, when disinfection is in observation phase.
•
The dosing is executed just after reading. Duration is limited to 6 minutes maximum per injection.
•
Whatever are the settings, maximum dosing time is 60 minutes per day.
•
Proportional-integral control logic allows for very safe operations and avoids risk of overdosing.
Setting the maximum dosing time is a way to adjust control power. Maximum dosing must be adjusted in accordance with
pool volume, water alkalinity and the feeder pump flow rate to provide best results.
The pH Control relay AUX 7 is protected and injection will be stopped in the case of, loss of flow, loss of pressure, pump off
securities, etc. for safety.
An alert will be generated if pH is not in the defined range. pH control will continue to operate normally.
An alert will be generated if pH does not change after 5 successive injections to indicate that the control is ineffective.
As a security, if the measured pH is out of limits (lower than 6.0 or higher than 9.5), pH control is stopped. An Alert message
is displayed prompting for water balance.
As soon as the pH re-enters the range 6.0 to 9.5, injection may restart.
