Page 5 Introduction Introduction These operating instructions provide information on the technical data and functions of the DULCOTEST ® sensor for free chlorine, type CLO 3 / CLO 4 1.1 Labelling of Warning Information Introduction These operating instructions provide information on the technical data and functions of the product.
Page 6 Introduction NOTICE! Nature and source of the danger Damage to the product or its surroundings. Measure to be taken to avoid this danger. – Denotes a possibly damaging situation. If the situation is disregarded, the product or an object in its vicinity could be damaged. Type of information Hints on use and additional information.
Page 7 Introduction 1.2 User qualification WARNING! Danger of injury with inadequately qualified per‐ sonnel The operator of the system / equipment is respon‐ sible for ensuring that the qualifications are ful‐ filled. If inadequately qualified personnel work on the unit or loiter in the hazard zone of the unit, this could result in dangers that could cause serious injuries and material damage.
Page 8 Introduction Functional limitations Regularly check the sensor for dirt. Check the sensor cap regularly for air bubbles adhering to it (visual check). Observe the applicable national guidelines relating to maintenance, service and calibration intervals. Operational prerequisites Only use the sensor in bypass fittings that ensure the correct flow parameters (l/h, see Technical data).
Page 9 Functional description Functional description Brief description of the function The DULCOTEST sensor for free chlorine CLO 3 / CLO 4 is a dia‐ ® phragm-free, amperometric three-electrode sensor. The DULCOTEST sensor for free chlorine CLO 3 / CLO 4 can be used ®...
Page 10 Functional description 2.3 Function These types of sensor work on the amperometric measuring prin‐ ciple in the special design of a potentiostatic measurement on three measuring electrodes. After the sensor has been electrically connected to the measuring device/controller, a potentiostat ensures that there is constant polarisation voltage at the working electrode, independent of the current flow.

Possible consequence: Fatal or very serious inju‐ ries. Please ensure when handling hazardous sub‐ stances that you have read the latest safety data sheets provided by the manufacture of the haz‐...
Page 14 Assembly 4.1 Filling electrolyte NOTICE! Perform the following work over a sink. After this, carefully re-close the electrolyte bottle. Unsealed electrolyte bottles may severely limit the storage period of the electrolytes. Remove the red end cap and cut off the top end of the spout of the electrolyte bottle with a knife.
Page 15 Refill the sensor cap if the measuring results are unclear during operation. The sensor needs to be regen‐ erated by ProMinent should the problem persist. Use a soft, moistened paper towel to wipe any remaining electrolyte from the two gold electrodes on the front of the sensor body.

Page 18 Too low a supply voltage may result in an incorrect measured value. The requirements are automatically met when con‐ necting the sensor to a ProMinent controller. Connect the socket of the 5-pin signal cable to the 4-pin plug connector of the sensor.
Page 19 Start up Start up Ä Chapter 1.2 ‘User qualifica‐ User qualification: trained user, tion’ on page 7 CAUTION! Incorrect metering due to sensor failure Possible consequence: Slight or minor injuries. Material damage. – If a sensor fails then there may be an incorrect measured value at the input of the measuring/ control unit.
Page 20 Zero point calibration If the sensor is operated with a ProMinent control unit, then zero point calibration is not generally necessary. Zero point calibration is recommended if you wish to use the sensor at the lower limit of the measuring range or for short-term measurement at 0.00 ppm.

Page 27 Hydrodynamic cleaning of the electrode surfaces Hydrodynamic cleaning of the electrode surfaces Ä Chapter 1.2 ‘User User qualification: instructed personnel qualification’ on page 7 The sensitivity (slope) of the sensor increases by approx. 20% when using hydrodynamic cleaning. The upper measuring range limit thereby falls accordingly.
Page 28 Hydrodynamic cleaning of the electrode surfaces A2802 Fig. 8: Dummy Remove the flow resister M34x1.5P (740207) at the lower end of the DGMa module and insert the flow nozzle CLO into the flow resister.
Page 29 Hydrodynamic cleaning of the electrode surfaces A2803 Fig. 9: Dummy Completely fill the lid of the cleaning ball container with cleaning balls (approx. 20...25 balls). Now pour the cleaning balls from above into the DGMa module of the CLO sensor. Refit the CLO sensor into the bypass fitting.
