Controller
IMPORTANT!
The measuring signal of the REDOX single-rod
measuring cell can be also configured to control the
disinfection.
4.5.4 Measuring input temperature
Always use a two-wire "Pt 100" sensor.
Calibration
Main menu >> Calibrate >> Temperature
The measuring input is factory-calibrated. If can be re-calibrated
if necessary.
To do this, measure the temperature of the sample water with
a reference thermometer and set the reading as a reference in
the controller.
4.5.5 Conductivity reading input
Record the increasing trend after brine or sea water baths fol-
lowing the quality of the brine. If for example a Technopool flow-
through chlorine electrolysis cell is used to generate the free
chlorine, brine water must be on hand.
The conductivity of the sample water can be measured and the
saline concentration kept constant. The measuring signal of the
conductivity measuring cell is converted into a standard 4 … 0
mA current signal in the conductivity transmitter.
Calibration
Main menu >> Calibrate >> Conductivity
Setting of the zero point is not necessary. Only the reference
value needs to be checked *). Afterwards the slope is indicated in
the measuring cell. The accuracy of resistivity measurements is
monitored throughout the process.
Computationally the measured value is indicated as %-salt con-
tent and in mS/cm. Example: 4 … 0 mA corresponding 0 … 0
mS/cm.
current (mA) salt content (mS/cm) salt content (%)
4.00 0 0.00
8.00 5.0 0.5
1.00 10.0 0.50
16.00 15.0 0.75
0.00 0.0 1.00
*) As the conductivity transmitter is factory-calibrated, the setting
can be calculated from the following table. (The current measured
[mA] is shown in the calibration window). A hand-held measuring
device can be used for the reference measurement.
4.6 Explanation of digital inputs
The controller has some digital inputs to monitor operating con-
ditions. These have different effects:

The switch direction, Normally Open (N.O.) or Normally Closed
(N.C), can be activated and set in the menu Service >> Switch
Inputs.
The start-up delay is set in the menu Service >> Start-up.
After filter cleaning there is normally a long period of time before
the water sampling station can be refilled with representative
water from the swimming pool. The controller therefore works
during the start-up delay with the control output that was active
immediately before filter cleaning.
NOTICE!
The start-up delay is also active after the power sup-
ply has been switched on and after calibration.
NOTICE!
The filter pumps of privately operated swimming
pools are often switched on for just a few hours a
day. To ensure the controller can work reliably despite
the run-in time of the sensors, the run-in term should
be set as follows.
Disinfection sensor Recommended start-up delay
Chlorine measuring cell CS10 100 s
REDOX electrode 600 s
