Application: Controlling water quality in
a swimming pool.
■ Control systems located in machine
rooms.
■ Manufacturers of swimming pools, OEM
wholesalers of swimming pools.
Description of customer needs:
■ Control physical ?ltration of water
(using a ?lter).
■ Set ?ltering time in relation to the
temperature of the bathing water.
■ Control the neutrality of the water (pH).
■ Control the level of water disinfection
(Redox: chlorine-based disinfectant).
Application Water treatment
How the application works:
Water needs to be ?ltered regularly to remove solid particles
(sand, plant matter, insects, suntan oil, hair, etc.) and keep it clear.
The higher the temperature, the longer it takes to ?lter.
Water quality is essential for swimming pool applications. Regular
checks should be carried out in respect of:
- Neutrality of the water (should be 7.2 < pH < 7.5)
- Level of water disinfection (optimum level of chlorine in water for
destroying bacteria)
Both pH and Redox are measured using probes submerged in
pipes, a buffer container, or an analysis chamber. These probes
analyse the presence of hydrogen (H+) and chlorine (Cl) ions
capable of oxidising an electrochemical couple within the probe.
This oxidation generates an electrical voltage, expressed in mV,
which is forwarded to the PLC. After a calibration process, the PLC
converts this into values for the pH and Redox.
Crouzet solution:
Millenium 3 XD10 24 V DC logic controller.
■ 100 - 240 V AC/24 V DC power supply.
■ XA04W “application-speci?c” analogue extension: Measuring
extension card in modular casing.
■ pH probe, ORP (Redox) probe and Pt100 probe.
■ As an option: Modem communication solution with GSM
for sending alarms.
The benefits of the Crouzet solution:
■ “All-in-one”: the same PLC controls the physical ?ltration and
Private swimming pool
chemical treatment functions.
Simple, straight-forward programming.
Additional Millenium 3 functions available to control other
application requirements (lighting control, vacuum pumps for
pool cleaning brushes).
The most compact extension on the market (72 mm).
Optional SMS alerts via integrated Millenium 3 modem solution.
Crouzet also has expertise in the area of position sensors
and micromotors, and is able to offer motorisation solutions
(swimming-pool covers using winders or curtains).
