device and loss of warranty.
All safety mechanisms and guards must be refitted and reacti-
vated as soon as the work is complete.
NOTICE!
Apart from an incorrect installation also wrong con-
troller settings (default settings, data of the param-
eter and configuration level, and internal changes of
the instrument) can impair or damage the process
normal functions.
There should always be a safety device that is independent of the
controller. Configurations may only be carried out by technical
personnel! If necessary use password protection! Always comply
with the safety regulations and accident prevention laws of the
country of use.
1.9 Self-made modifications and spares procurement
The device may be converted or changed only by qualified tech-
nical personnel.

personnel, faults and hazards can arise during operation. In this
case, the manufacturer declines any liability.
NOTICE!
Genuine spare parts and sensors authorized by the
manufacturer ensure greater safety. Otherwise the
guarantee expires.
NOTICE!
Local safety instructions and applicable regulations
must be observed. The operating manuals of prod-
ucts used in the system must be observed, in par-
ticular the operating manual of the peristaltic pump
which is included separately with the water sampling
station.

3.1 Swimming pool water system
In a typical installation a circulation pump delivers the bathing
water through a filter. When the disinfectant and the pH-adjust-
ing solution (normally a pH reducing agent) have been added, the
water returns to the pool via inlet nozzles. The water sampling
system is incorporated in this system.
IMPORTANT!
A continuous flow of water is required to achieve suc-
cessful sampling and control of the water quality. Any
deviations in the flow velocity and frequent interrup-
tions to the flow will have a negative effect on the
control system and hence the water quality.
The following functional diagram illustrates the instal-
lation.

IMPORTANT!
To prevent the output relays from bonding in the case
of a short in the load circuit, it must be separatly
protected with the maximum relay switching cur-
rent. For inductive loads, apply a protective circuit to
the contacts of the relays (spark suppression). The
manufacturer recommends the use of the interfer-
ence suppression module / spark suppression device
(part no. 78614).

4.5 Measurement value inputs
This chapter exemplifies the chemical and physical correlation,
which is necessary to understand the behaviour of the input
measuring values.
The input measuring values are examined for:
Free chlorine
pH value
REDOX potential
Temperature
Conductivity
In doing so an important element is the calibration of the sen-
sors.
NOTICE!
When set up the unit for the first time, care should be
taken to perform individual calibration of each output
immediately after connecting the sensors in the sys-
tem. The controller monitors all calibration processes
based on reasonable parameters (zero point and
transconductance). The measured data is recorded.
Non calibrated and „Roughly calibrated” value inputs
are marked out in clear text. „Roughly calibrated”
values are shown on the main display in red.
NOTICE!
Please note that time delays are possible due to the
initial running times of the sensors.
The limits of „Roughly calibrated” are:
measurement value limits
Transconductance pH value < 53 or > 61 mV/pH
zero point pH < -40 or > 40 mV
REDOX transconductance < 0.85 or > 1.2 mV / mV
Chlorine transconductance for amperom.
measuring cell
< 3 or > 100 µA / mg/l
The remark „roughly calibrated” sheds light on the calibration
quality and the conditions of the electrochemical electrodes. If
necessary you can look for calibration faults and replace the sen-
sors at the appropriate time. You can use the sensors unchanged
until replacement. The controller will continue to work normally.
NOTICE!
Correct calibration is a pre-requisite for the safe op-
eration of the water sampling station. The calibration
must be checked at regular intervals.
4.5.1 Free chlorine measurements input
The free chlorine reading depends on the pH value of the water
sample. This is based on the reaction of the chloride ions at dif-
ferent pH values. This relationship determines the chlorine dis-
sociation curve (see Fig. 4.5.1).

Fig. 4.5.1: Chlorine dissociation curve as a function of the pH value
For photometric measurements the pH value of the sample is
buffered to approx. pH 6.5. As a result the measurement has a
higher effective chlorine content than is actually in the bathing
water. In the presence of high pH-values significant differences
will occur between expected and actual disinfection if assessed
by photometric analysis. The main display will show therefore
2 free chlorine values: the photometry value and the the effec-
tive chlorine content ("eff. chlor") to kill germs at the current pH
value.
NOTICE!
For saline bathing water use a platinum/silver chlorine
measurement cell instead of platinum/copper.
Calibration
Before starting the calibration, the upper value of the measuring
range of the sensor must be specified (Main menu >> Menu 2
>>Service >> Inputs). In non-DIN 19643 operated swimming
pools it is preferable to use the 0 … 2 mg/l measuring range.
The input can then be calibrated using a two-point calibration
(Main menu >> Calibrate >> Free Chlorine >> 2 point):
The physical value (µA) measured at the sensor is shown on the
display during calibration.
Calibration method 1: Zero-point calibration
The sample water flow is therefore stopped. (ball valve on water
sampling station inlet). The value of the physical quantity shown
on the display (approx 5 … 10 μA) can be saved with "OK" as
soon as it stops changing. The device automatically changes to
the next menu section.
Calibration method 2: DPD
The sensor is operated with sample water. If the physical value
on the display does not change any more, the chlorine content in
the sample water is determined via a photometer (DTP method).
To avoid signal deviations during DTP determination as reading
errors, the sample water must be taken from the measuring cell
and the current signal at the time of removal of the sample water
must be saved. The content of chlorine in water is measured by
means of the DPD method. The value must be set in the control-
ler and saved by pressing OK.
After storage the transconductance value of the chlorine sensor
is shown. The typical transconductance reading is 25 µA … 35
µA (depending on water sample) per mg/l of free chlorine. The
accuracy of resistivity measurements is monitored throughout
the process.
1-point calibration is often sufficient (reference value 2 only) to
check the chlorine content after optimization.
4.5.2 Measuring input pH value
The voltage signal transmitted by the combination electrode is
proportional to the pH value. This voltage is defined by the Nernst
voltage. The Nernst voltage ist he change in voltage per pH unit.
It depends on the temperature of the medium to be measured
(see corresponding technical literature or German Standard DIN
19261).
The Nernst voltage is measured between the pH glass electrode
and a reference electrode. Mechanically these two electrodes are
integrated in a pH combination electrode.
Calibration
Calibration of the electrode may be performed by ways of "2-
point calibration" with 2 buffer solutions or by "1-point calibra-
tion" with final input of the resistivity value. "Single point calibra-
tion" requires the transconductance of the single-rod measuring
cell to be measured in a laboratory beforehand.
The actual voltage of the single-rod measuring cell and the
theoretical value (ideal value) of the buffer solution setting are
displayed during calibration. This allows the rating of the single-
rod measuring cell to be determined during calibration, assuming
fresh buffer solutions.
The reaction time for any brand new electrode is just a few sec-
onds and the electrode is considered as fully adjusted when the
physical reading becomes stable. In the case of older combina-
tion electrodes the reaction time may be longer.
2-point calibration
Main menu >> Calibrate >> pH value >> 2 point
Buffer 1: Zero-point calibration
Submerge the pH combination electrode in a buffer solution
which is equivalent or close to the zero point of the electrode.
The ideal zero point (O mV) of the combination electrode is pH
7.00, the actual zero point, however, deviates slightly from this
value. For zero-point calibration a buffer solution of pH 6.80 is
available from the manufacturer. When immersing the pH single-
rod measuring cell in this solution, a voltage of 12 mV can be
displayed theoretically. The physical value actually measured is,
however, always different from the theroretical one.
When the physical value on the display becomes stable, you may
save the calibrated value by pressing „OK“.
IMPORTANT!
Should the actual measured voltage strongly differ
from the design zero-point of the electrode, it means
there is a zero-point drift of the electrode. Zero-point
drift should not exceed the specifications of the DIN
Standards 19265. In the event of zero-point drift
exceeding ± 40 mV, TOPAX DX gives a poor probe
calibration warning.

20 | EASYPOOL SMART 02 Operating Manual
Controller
Buffer 2: Transconductance calibration
Accurately clean the electrode with deionised or distilled water
before calibration of the resistivity.
NOTICE!
Avoid rubbing off glass electrodes as this will pro-
duce a static charge on the electrode. This would
result in faulty readings.
For slope calibration a buffer solution must be used which differs
at least 2 pH units from the zero point. For zero-point calibration
a buffer solution of pH 9.27 is available from the manufacturer.
If you are using a different buffer solution for transconductance
calibration, the value for this buffer solution must be set on the
controller. When immersing the single-rod measuring cell in the
buffer solution (Ph = 9.27), a theoretical voltage of -134 mV
should be displayed. The physical value actually measured is,
however, always different from the theroretical one. Confirm pre-
setting by pressing the “OK“ key.
Then the slope value of the combination electrode is displayed.
In accordance with the DIN Standards 19265 the resistivity if an
electrode should range between 52 and 59 mV per pH-value.
The zero-point stability and reasonableness of the transconduct-
ance are monitored.
IMPORTANT!
If the transconductance reading differs considerably
from these values, check the single-rod measuring
cell or the connecting cable and the plug connectors.
Should zero-point and resistivity values of the com-
bination electrode exceed the admissible tolerances,
the system notifies the operator with a warning mes-
sage. In this case provide for immediate replacement
of the electrode.
IMPORTANT!
Store buffer solutions in a cool and dark place! Con-
sider its durability. Make sure that the buffer solution
is not contaminated. That is why you should not put
single-rod measuring cells directly from one buffer
solution into another solution.
1-point calibration
Main menu >> Calibrate >> pH value >> 1 point
Single-point calibration may also be used for pH calibration with
a single-rod measuring cell (see section 6, menu 1.2).
Submerge the pH combination electrode in a buffer solution
which is equivalent or close to the zero point of the electrode.
The ideal zero point (O mV) of the combination electrode is pH
7.00, the actual zero point, however, deviates slightly from this
value. The manufacturer provides a buffer solution with pH value
of 6.80 for zero-point calibration. When immersing the pH single-
rod measuring cell in this solution, a voltage of 12 mV can be
displayed theoretically. The physical value actually measured is,
however, always different from the theroretical one.
When the physical value on the display becomes stable, you may
save the calibrated value by pressing „OK“.
Now enter the resistivity of the electrode.
IMPORTANT!
Should the actual measured voltage strongly differ
from the design zero-point of the electrode, it means
there is a zero-point drift of the electrode. Zero-point
drift should not exceed the specifications of the DIN
Standards 19265 (±40 mV).
Offset compensation
In accordance with DIN 19643, the control of the pH value is to
be made with an electrical metric pH value measurement.
By external influences it can be possible that the pH value of
the electrical metric measurement, measured by hand with the
photometer, deviates by a constant value. The "Offset compensa-
tion" menu allows you to compensate for this difference (setting
range +/- 0.30 pH).
NOTICE!
The offset value is set to „0“ after every new calibra-
tion.
4.5.3 REDOX potential measurement input
The REDOX potential is measured using the REDOX single-rod
measuring cell. It measures the voltage which exists in the water
due to oxidizing and reducing ions.
NOTICE!
For saline bathing water use a RESOX single-rod
measuring cell with a gold electrode instead of a
platinum electrode.
Calibration
Main menu >> Calibrate >> REDOX
Calibrate the combination electrode during startup. To calibrate
the REDOX single-rod measuring cell only one reference value
must be set. The physical value (mV) measured at the sensor is
shown on the display during calibration.
To calibrate you need a buffer solution in order to measure a
defined voltage in conjunction with the REDOX single-rod meas-
uring cell (default value: 468 mV). This value can be changed
when using other buffer solutions and/or combination electrodes
with other electrolytes. To change, use the buttons on the control
panel. The voltage actually measured is shown on the display
during calibration. This value has a small deviation from the given
value of the buffer solution. The deviation should not be bigger
than approx. 10%.
The accuracy of resistivity measurements is monitored through-
out the process.
After a reaction time (approx. 1 minute) the physical value does
not change anymore.
The reference value can be now entered and saved by pressing
the “OK” button.
IMPORTANT!
With old combination electrodes the response time
can become larger and vary. Furthermore the meas-
ured value can be largely different from that of the
buffer solution. This signifies that the combination
electrode must be checked and possibly replaced.
