1.2 Description

1.2.1 Versions

Versions The DEPOLOX® Pool is available in different versions:

With a non-pressurised flow block assembly

With a pressurised flow block assembly

each for

200...240 VAC (can be switched over to 100-120 VAC)

24 V DC

The non-pressurised and pressurised versions vary in that a different

number of sensors can be installed and also with regard to the design

of the sample water outlet (refer to section 1.2.2 Design). The non-

pressurised version is used when the sample water is freely dischar-

ged. With the pressurised version the sample water is returned to the

system circuit.

Description DEPOLOX® Pool

1.2.3 Function

Overall function Up to seven measured values can be indicated by specific process

components:

Free chlorine*

Combined chlorine*/Total chlorine*

pH value*

Redox potential

Conductivity*

Temperature

The value of the combined chlorine is calculated from the difference

between the total chlorine and the free chlorine.

The graphic display shows the measured data, limit values and set-

points as numeric values, diagrams or a trend line.

All measured values can be displayed at the same time. The pre-set li-

mit values meet the requirements of DIN 19643 "Treatment of water of

swimming-pools and baths".

Flow block assembly The flow block assembly guarantees a stable measurement signal with

Robust sensors

Constant sample water flow rate with the aid of the flow control val-

ve

Hydrodynamic sand cleaning of the chlorine sensor measuring

electrodes

Optimum flow around all sensors

The multi-sensor integrated into the flow block assembly monitors the

constant sample water flow rate, registers the sample water tempera-

ture and ensures wide-spread equipotential grounding (sample water

grounding).

* These measurements are automatically temperature-compensated.

Description DEPOLOX® Pool

20 WT.050.570.000.DE.IM.0714

Electronic module The electronic module serves for the visualisation and subsequent pro-

cessing of the measured data as well as process control.

Positioners or various dosing pumps can be connected to the control

outputs of the process control unit.

The following functions are possible:

Dosing of the disinfectant

Adaptation of the control parameters to the circulation

(ECONOMIC operating mode)

Correction of the pH value

Control of the activated powder carbon or UV disinfection unit

Addition of the flocculant (controlled by circulation and the pH va-

lue)

Up to four relay outputs can also be used as alarm contacts. They can

be freely configured. Multiple allocation of events is possible.

The following special functions are also integrated into the control unit:

The DIN contact

Flocculation control

DIN contact The unit contains a DIN contact. If the set hygiene parameters are met,

this information is forwarded to the swimming pool control unit:

Cl2  0.3 ... 0.6 mg/l

pH  6.5 ... 7,6

Redox  > 750 mV

Cl-N  < 0.2 mg/l

These limits can be freely set.

Adaption programme The adaption programme automatically determines the control para-

meters for free chlorine during commissioning.
