2 Brief Description of the FunctionsBrief description of the functions
The DULCOTEST® CGE is a membrane-covered, amperometric two-electrodesensor. Use the DULCOTEST® CGE tomeasure the concentration of total avail‐able chlorine in swimming pool water orwater of a similar quality.
The chlorine compounds dissolved in thewater pass through the sensor membraneand are electrochemically transformed onthe working electrode. The primary currentsignal resulting from the transformationcan be evaluated to determine the con‐centration (of chlorine).
The integral sensor signal transformerconverts the primary sensor current intoan output signal of 4 ... 20 mA.
Typical applications:
n Measurement of total availablechlorine in swimming pool water– from stabilised chlorine (chloro
(iso) cyanuric acid derivatives),also in combination with freechlorine from electrolysis pro‐cesses, with and without dia‐phragm between the anode andthe cathode.
2.1 Measured variableThe sensor measures the concentration oftotal available chlorine in swimming poolwater. This is understood as being thetotal chlorine, bound to organic carriermolecules (e.g. cyanuric acid) and theresulting free chlorine released (HOCl andOCl- ). The sensor measures independ‐ently of the content of combined chlorine(chloramines)
The measuring signal of the CGE3 sensorfollows the value determined by theDPD-1.

6 Putting the Sensor into Operationn User qualification: trained user, see Ä Chapter 1.2 ‘Users' qualifications’ on page 6
WARNING!
Danger from hazardous substances!Possible consequence: Fatal or very serious injuries.
Please ensure when handling hazardous substances that you have read the latestsafety data sheets provided by the manufacture of the hazardous substance. Theactions required are described in the safety data sheet. Check the safety data sheetregularly and replace, if necessary, as the hazard potential of a substance can be re-evaluated at any time based on new findings.
The system operator is responsible for ensuring that these safety data sheets areavailable and that they are kept up to date, as well as for producing an associatedhazard assessment for the workstations affected.
CAUTION!
Incorrect metering due to sensor failurePossible consequence: Slight or minor injuries. Material damage.
– If a sensor fails then there may be an incorrect measured value at the input ofthe controller/measuring instrument
– This may result in uncontrolled metering– The operator should therefore ensure that no subsequent damage results from
this
Putting the Sensor into Operation
18
CAUTION!
Incorrect metering due to premature ageing of the sensorPossible consequence: Slight or minor injuries. Material damage.
Measure: Do not electrically disconnect the sensor during measuring breaks.
Exception: If there is a break between measurements lasting more than a week andthe proportion of disinfectant in the sample water falls during this period to 0 ppmthen electrically disconnect the sensor.
– An extra run-in period will be necessary following operation without disinfectant.Switch on feeder assembly with a time delay if necessary.
Run-in period
The sensor requires a specific run-in period to display a steady display value.
Initial commissioning: 1 - 24 h (typically 6 h)*
Recommissioning: 1 - 24 h (typically 3 h)*
Electrolyte or membrane change: 3 h
* the exact run-in time depends on the application.
6.1 Calibration
CAUTION!
– Perform a slope calibration everytime if the sensor has been tam‐pered with (e.g. electrolytereplacement etc.)!
– Repeat slope calibration at reg‐ular intervals to ensure the per‐fect operation of the sensor! Ifthere are no other regulations,then only calibrate the sensorevery 3-4 weeks for use indrinking water and swimmingpool water.
Putting the Sensor into Operation
19
– Avoid air bubbles in the samplewater! Air bubbles, which adhereto the sensor membrane, canresult in too low a measuredvalue and thus lead to dangerousincorrect metering.
– Please note the pertinent nationalguidelines for calibration inter‐vals!
Prerequisites– The sensor is ready for meas‐
uring (wait for run-in period)– Constant flow rate at the in-line
probe housing– Constant temperature of the
sample water– Each time the sensor is removed
or inserted, wait until the run-inperiod has expired and a con‐stant measured value is ach‐ieved, a minimum of 15 minutesto avoid drifts caused by temper‐ature compensation.
– No concentration fluctuations ofthe feed chemical in the samplewater
– Constant pH value within the per‐missible range
– Ensure that the sample is takenat the place the sensor isinstalled
Zero point calibration
If the sensor is operated with a ProMinentcontroller, then zero point calibration is notgenerally necessary. Zero point calibrationis recommended if you wish to use thesensor at the lower threshold of the meas‐uring range.
1. Place the sensor in a vessel withclean water free of chlorine and oxi‐dising agent (e.g. mineral waterwithout gas).
2. Use the sensor to stir it until themeasured value on the controllerremains stable for 5 minutes.
3. Calibrate the controller to zero inaccordance with its operatinginstructions.
4. Refit the sensor into the in-lineprobe housing (DGM; DLG III).
Slope calibration
1. Use an appropriate referencemethod (e.g. DPD 1) to determinethe chlorine content of the samplewater.
2. Set the determined value on thecontroller in line with its operatinginstructions.
ð Repeat calibration during com‐missioning, and on the day fol‐lowing any tampering with thesensor.
