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 set­points as numeric values, diagrams or a trend line.

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

DEPOLOX® Pool Description

WT.050.570.000.DE.IM.0714 21

Safety functions The safety functions integrated into the control unit are:

 Safety cut-out if the circulation fails and/or if the dosing tank signals

that it is empty and also if the sample water supply fails

 Dosing time monitoring and the dosing time delay
 Alarms
 External stop for all controllers
 Function "positioner closed" in the event of power failure

(only with external power supply for positioner)

 Password protection on two levels

Infrared calibration Infrared calibration is performed in conjunction with the photometer

P42 i-cal. The measured calibration value is automatically transmitted
at the correct time with infrared light.

ECONOMIC

operating mode

If circulation is reduced when required, for example during the night,
the device switches to ECONOMIC operating mode when it is set ac­cordingly. The control parameters for chlorine and flocculation are au­tomatically adapted. To this purpose the device uses a second set of
parameters.

1.2.4 Controller modes for chlorine control

From firmware version 2.0 of the DEPOLOX® Pool, there are two opti­ons
for setting the concentration of disinfectant:

 Cl2-Single feedback closed loop control

In this mode, the required Cl2 value is held at the setpoint using the
PI single feedback closed loop control (standard chlorine
regulation).

 CEDOX control

In this mode, the chlorine setpoint is continuously optimised using a
PI single feedback closed loop control in order to maintain a cons­tant redox value. For this procedure, the setpoint entered is not Cl2
as normal, but the required redox potential is set as the setpoint.
A specially developed CEDOX mode calculates the amount of free
chlorine required in the water based on the demand. This internal
chlorine setpoint is used to measure the required quantity of disin­fectant using the PI single loop feedback controller.
The variable or optimised Cl2 setpoint must remain between the
“Min setpoint” and “Max setpoint” limit values (Menu 1.1.4).

DIN 19643 specifies the following Cl2limits:
Min = 0.30 mg/l and Max = 0.60 mg/l.

Requirement for CEDOX control:

- Chlorine measuring and control

- pH measuring and control

- mV measuring

NOTE
CEDOX control only works if the pH value deviates from the pH setpoint
by no more than 0.30

The CEDOX control system is based on the following principle:

Description DEPOLOX® Pool

The example diagram below shows how the CEDOX mode works:

Notes for settings for CEDOX control:

The parameter "mV delay time” (Menü 1.3.1) defines the reaction times
of the redox electrode and has a delaying effect on the setpoint optimi­sation of the chlorine control.
The Cl2 setpoints determined by the CEDOX mode must always be
between the limit values Cl2 min setpoint" and "Cl2 max setpoint". If
these setpoint limits are reached, the mV measured value may vary
from the mV setpoint.

Notes for startup/calibration of CEDOX control

After calibrating the redox electrode, the setpoint optimisation is out of
service for 2 hours, as the redox electrode does not supply reliably si­gnals during this period. During this time, the DEPOLOX

®

Pool uses a
fixed temporary Cl2 setpoint. This temporary Cl2 setpoint is the last
current Cl2 before the calibration (can be altered manually, Menu 2.1.1
or 2.1.3).
When the chlorine measuring is calibrated, the DEPOLOX

®

Pool auto-

matically calculates a new Cl2 setpoint if deviations are detected.

DEPOLOX® Pool Description

WT.050.570.000.DE.IM.0714 25

What can be achieved by using CEDOX?

 Reduction of disinfectant consumption

(as much chlorine as necessary and as little chlorine as is possib­le).

 The optimum control of the Cl2 setpoint based on the redox potenti-

al means that the lowest possible Cl2 setpoint is always used and
thus disinfectant saved.

 Extension of reduced operation leads to longer energy saving times

and increased savings on energy and water.

 If the circulation is reduced, which is controlled using the DIN va-

lues, the automatic increase in the chlorine content can keep the
redox potential in the good range for longer and thus extend the re­duction of the circulation.
Attention: However, this can lead to increased disinfectant con­sumption

 Optimising the water quality, especially in swimming pools with

heavy fluctuations in usage (e.g. outdoor pools) or with long periods
of no usage.

NOTE
CEDOX does not mean that disinfection systems can be made smaller!

1.2.5 Combinations of controller modes

DEPOLOX® Pool gives you the option of running various controller mo­des in combination with ECO mode.

The operator can select four different controller modes:

Cl2 single feedback

closed loop control

Normal mode: Cl

2 setpoint

ECO mode: Cl

2 setpoint ECO

Cl2 setpoint: In this mode, the required Cl2 value is held at the setpoint
using the PI single feedback closed loop control.
Setting parameters: Xp, Tn, setpoint
The flocculent control system measures at a constant rate.

Cl2 setpoint

ECO: In ECO mode, the reduced Cl2 value is held at the

setpoint using the PI single feedback closed loop control. There is a
digital input to switch the system to ECO mode.
ECO setting parameters: Setpoint

ECO, XpECO, TnECO

The flocculent control system measures at a constant rate.
This ECO mode can also be used for disinfectant control in combina­tion with reduction of the circulation.

CEDOX Normal mode: CEDOX

ECO mode: CEDOX

ECO

(Version 2.00 and higher)

CEDOX:

In this mode, the setpoint entered is not Cl2 as normal, but
the required redox potential is set as the setpoint. The specially devel­oped CEDOX mode calculates the amount of free chlorine required in
the water based on the demand. This internal Cl2 setpoint is used to
measure the required quantity of disinfectant using the PI single loop
feedback controller.
Setting parameters: Redox setpoint, Xp, Tn
The flocculent control system measures at a constant rate.

CEDOX ECO:

In CEDOX ECO mode, the mode is also controlled
based on a redox setpoint. There is a digital input to switch the system
to ECO mode. The device calculates the required concentration of free
chlorine in the water based on load and controls this Cl

2 setpoint using

the PI single loop feedback control.
Setting parameters: Redox setpoint

ECO, XpECO, TnECO

The flocculent control system measures at a constant rate.
This ECO mode can also be used for disinfectant control in combina­tion with reduction of the circulation.

DEPOLOX® Pool Description

WT.050.570.000.DE.IM.0714 27

Cl2 + CEDOXECO Normal mode: Cl2

ECO mode: CEDOX

ECO

(Version 2.00 and higher)

Cl2:

In this mode, the Cl2 setpoint is controlled by a PI single feedback
closed loop control.
Setting parameters: Xp, Tn, Cl2 setpoint,
The flocculent control system measures at a constant rate.

CEDOX ECO:

In CEDOX ECO mode, the mode is controlled based on
the mV setpoint (see under CEDOX). There is a digital input to switch
the system to ECO mode.
Setting parameters: Redox setpoint

ECO, XpECO, TnECO

The flocculent control system measures at a constant rate.
This ECO mode can also be used for disinfectant control in combina­tion with reduction of the circulation.

Peak-chlorination

This function is primarily an addition in combination with CEDOX cont­rol when low concentrations of chlorine occur frequently.

The “peak-chlorination” function can guarantee pool hygiene, even
when the chlorine values are low and DIN parameters are complied
with, it can also ensure the prevention of algae growth.

At a maximum of 5 freely definable times per week, the DEPOLOX

®

Pool automatically adjusts to a higher chlorine value, which can even
be set to above the measurement range. These times can be repeated
weekly, or every two, three or four weeks.

The duration of the peak-chlorination can be defined and starts when
the peak-chlorination setpoint is reached.

For safety reasons, the system includes a time limit which defines the
maximum time for which this peak-chlorination value can be activated.

If the peak-chlorination value is not reached during this time, the pro­cess is cancelled and an error message is displayed.

Switching off

peak chlorination

There is the option of switching off the alarm and the overall chlorine
control during peak-chlorination. Once the Cl

2 value is back at the set-

point, the alarm and the total chlorine control are reactivated.

Adaption

The adaption menu (1.1.6) contains the parameters for Tu, Ts, Tu

ECO

and TsECO. Depending on the mode in which the adaption run is car­ried out, the relevant times are calculated (in normal mode Tu and Ts
and in ECO mode Tu

ECO and TsECO). At the same time, the times

determined are used to calculate the control parameters Xp, Tn or
XP

ECO und TnECO.

All the times and control parameters can also be entered manually if
they are known. If the times Tu and Ts or Tu

ECO and TsECO are

adjusted manually, the corresponding control parameters Xp and Tn
or. Xp

ECO and TnECO are calculated at the same time.

Description of the

operating modes

MANUAL In the MANUAL mode dosing is not automatically controlled. The va-

lues must be continuously monitored.
The MANUAL mode is used:

 In the event of any possible system faults
 During maintenance/cleaning work or while checking the system

NOTE

The system password is required to change the settings.
When the MANUAL mode is set:

 The pumps are off, the positioner remains in its current position, if

necessary unlock the positioner and close either by hand or with
the Handdos menu.

AUTOMATIC Automatic control of chlorine, pH, combined chlorine, conductivity and

addition of flocculant

AUTO with ECO Control of the chlorine value and flocculation is performed in accor-

dance with the ECO parameter set if the Economic parameter is acti­vated with DI 2 or 3.

STOP The STOP mode is automatically activated:

 When the sample water flow is faulty
 When a stop signal is received via the digital inputs

After activation:

 The pumps switch off, the positioner closes, mA analog output 0 %

If stop conditions no longer prevail, the mode is automatically swit­ched to Automatic.

ADAPTION The ADAPTION mode is activated if adaption is started in the Cl

2

menu

(menu 1.1) in the display 1.1.6.
For adaption refer to section 2.

NaCl in g/l or NaCl in %
Depiction of the sodium chloride content in g/l or in % determined
based on the conductance value of the sample water. In addition to
sodium chloride (salt), water contains other conductive substances as
well, which are also included in the calculation. The zero display only
serves to indicate the determined approximate sodium chloride
content

.

TDS:
TDS = Total Dissolved Solids
The TDS factor depends on the composition of the measured water
and has to be evaluated for each type of water.

Explanation of system

settings

1)

Measure.filter The measurement filter serves to compensate measurement value

fluctuations in the event of irregular measurement value signals.

2)

Feed delay The feed delay delays dosing start when the device is switched on and

when the operating mode has been changed. Running of the selected
time can be cancelled with the "Acknowledge" key.

3)

Overfeed delay The maximum dosing time determines how long all control outputs run

at a 100 % dosing capacity in both manual and automatic mode. The
respective controller output is switched off after this time. When the set­ting is "00:00:00" this function is switched off.

4)

Samp.water delay The sample water delay (DI 1) determines the time after which dosing

is deactivated, e.g. in the event of sample water stop. DI 1 flashes while
the delay time is running.

5)

System restart When the applications are changed the device must be restarted with

System Restart.

6)

Delete diagram The saved values of the past 7 days are deleted.

7)

Standard values Customer settings are deleted (except for the selected application), the

system is reset to the works settings. The sensors must be recalibra­ted.

8)

Delete dos.avg The average dosing values from display 1.8.3 are reset to zero.

CAUTION!

 With the pressurised version, when calibrating the sensor measu-

ring modules

 pH value
 Redox potential
 Conductivity

you must also perform the following:
Before calibration:

1. Close the ball valves on the inlet and outlet.

2. Depressurise the unit. To this purpose open and close the
knurled nut on the drain briefly.

After calibration:
Open the inlet and outlet.

The electrode fingers or membranes on the sensors are extremely sen­sitive! Do not touch, soil or damage.

WARNING!
Some of the buffer solutions are caustic and can cause burns.
Avoid contact with the eyes or the skin.

NOTE

 To prevent the output of non-permissible control sig nals during cali-

bration, the "Hold function" in the system menu (display 1.6.1)
should be set to "On" (mA-outputs and controller outputs then re­main constant during calibration).

 The lower clip must be fitted into the top mount if the supplied bea-

ker is to be used, if a bag with calibration solution is used it must be
fitted into the bottom mount.

 Concerning the frequence of calibration refer to the corresponding

standards (e.g. DIN 19643). Refer to the recommended intervals in
the maintenance chapter.

1.5 Maintenance

NOTE

The liability for defects is only valid if maintenance work is performed
as specified.
Adhere to the appropriate standards, regulations and locally applicable
guidelines.

Check for tightness

(daily)

Check the entire measuring device including all screw connections for
leakage. Repair any leakage points immediately!

Important: Air bubbles in the cell body influence the measuring

accuracy. The cause must be determined and remedied.

Check the cell sand

(weekly)

Check that there is sufficient sand in the cell body. The cell sand must
be swirled around in the bottom section of the cell body. The cell sand
is necessary for cleaning the electrodes of the chlorine sensor and
must be replenished or replaced when required.

NOTE

When fresh sand is replenished, the electrode current can increase
slightly for approximately 2 to 3 hours. During this time do not perform
any calibration.

Task Period/interval

Replacing the cell sand

(every 6 months)

The cell sand required for constant cleaning of the chlorine sensor
grinds itself down with time until it is very fine. It must therefore be re­placed regularly. The cell sand is supplied in a plastic bottle, the cap
serves as a measure.

Fig. 20

1. Close the ball valve on the sample water inlet (5, Fig. 20). On the
pressurised version also close the stop valve on the sample water
outlet (3, Fig. 20).

2. On the drain (4, Fig. 20) remove the drain screw and empty the cell
body (1, Fig. 20). On the pressurised version temporarily loosen a
plug or sensor to allow air to flow in.

3. When the cell body is empty, rinse the drain screw to remove the
sand and screw it in place again.

4. Remove the housing cover of the flow block assembly. To this pur­pose press the two buttons (1, Fig. 21) on the top of the housing.

5. Unscrew the flow distributor cap (2, Fig. 20). The remaining water
drips out.

6. Rinse the sand out of the flow distributor cap.

Fig. 22

7. Fill the cap of the cell sand bottle until it is one third full with new
cell sand and pour into the middle of the flow distributor cap (1,
Fig. 22).

8. Screw the flow distributor cap back on.

9. Open the ball valve on the sample water inlet and if necessary the
sample water return line. The cell body fills with sample water once
more. A rotating air bubble does not affect measurement, it disap­pears on its own.

10. Replace the housing cover and click into place.

After 2 to 3 hours running-in time perform chlorine zero point calibrati­on. If necessary repeat the chlorine zero point calibration after 24
hours.

Total chlorine sensor:
Replace the electrolyte
Replace the membrane

cap

CAUTION!

Do not touch or damage the reference electrode and keep it clean!
Before unscrewing the membrane cap 3, remove the elastomer seal 5

to allow air into the vent hole 4. Not doing this will cause a vacuum to
occur which will damage the membrane. Do not remove the yellow­grey layer on the reference electrode 8. Do not move the yellow-grey
layer towards the gold working electrode 7!

1. Open the sensor. Before unscrewing the membrane cap 3, remove
the elastomer seal 5 to allow air into the vent hole 4.

2. Pour away the electrolyte.

3. Clean the reference electrode 8 with distilled water and dry with a
clean paper towel.

4. Fill the membrane cap 3 to the top with the enclosed electrolyte
(special electrolyte for brine application! Refer to the chapter Spare
partes).

1 Counter electrode 5 Elastomer seal
2 Electrode finger 6 O-ring
3 Membrane cap 7 Gold working electrode
4 Vent hole 8 Reference electrode

5. Clean the gold working electrode 7 with the enclosed lapping pa­per (special abrasive paper). To do this, place the special abrasive
paper on a paper towel. While holding on to a corner of the paper
move the tip of the electrode of the vertically held probe one or two
times over the rough side of the special abrasive paper.

6. Ensure that the elastomer seal 5 completely covers the vent hole.

7. While holding the electrode shaft in a vertical position, screw on the
cap onto the shaft. Surplus electrolyte will escape through the vent
hole 4 in the membrane cap below the elastomer seal. Do not hold
the vent hole 4 or press on the elastomer seal 5! The membrane
cap must be completely screwed to the electrode shaft so that no
gap remains between membrane cap and electrode shaft.

8. Wash away the escaped electrolyte with water.

9. The sensor requires a 1-2 hour run in time before a first calib ration
can be performed. The final calibration should be done after 1 day.
