Page 7: Product Safety
CCS140/141 Product description Ensure that electrical cables and hose connections are undamaged. Do not operate damaged products, and protect them against unintentional operation. Label damaged products as defective. During operation: ‣ If faults cannot be rectified: products must be taken out of service and protected against unintentional operation. - Page 8 Product description CCS140/141 Fixed cable Sensor shaft O-ring Large anode, silver/silver chloride Gold cathode Measuring chamber Membrane cap with dirt-repellent membrane Screw cap for securing the membrane cap A0037109 3.1.1 Measuring principle Free available chlorine levels are determined using hypochlorous acid (HOCl) in accordance with the amperometric measuring principle.
- Page 9 CCS140/141 Product description As hypochlorous acid splits up (dissociates) with an increasing pH value to form hypochlorite ions (OCl – ) and hydrogen ions (H ), the amounts of the individual components of free effective chlorine change with the pH value. For example, if the proportion of hypochlorous acid is 97 % at pH 6, it drops to approx.

Page 21: Commissioning
CCS140/141 Commissioning Commissioning Function check Prior to initial commissioning, ensure that: • The sensor is correctly installed • The electrical connection is correct. • There is sufficient electrolyte in the membrane cap and the transmitter is not displaying a warning about electrolyte depletion. - Page 22 Commissioning CCS140/141 Requirements The sensor reading is stable (no drifts or unsteady values for at least 5 minutes). This is normally guaranteed once the following preconditions have been met: • The polarization period has elapsed. • The flow is constant and within the correct range.

- Page 27 CCS140/141 Maintenance 9.2.3 Refilling the electrolyte NOTICE Damage to membrane and electrodes, air bubbles Possibility of measured errors to complete failure of the measuring point ‣ Do not touch the membrane or electrodes. Avoid damaging them. ‣ The electrolyte is chemically neutral and is not hazardous to health. Nonetheless, do not swallow it and avoid contact with eyes.
- Page 28 Maintenance CCS140/141 For recommissioning, follow the same procedure as for commissioning → 21. Ensure that no biofouling occurs during longer interruptions to measurement. Remove continuous organic deposits such as films of bacteria. Fit protection cap on sensor. To keep the membrane moist after the sensor has been removed, refill the protection cap with electrolyte or clean water.
- Page 29 CCS140/141 Maintenance 9.2.5 Regenerating the sensor During measurement, the electrolyte in the sensor is gradually exhausted due to chemical reactions. The gray-brown silver chloride layer that is applied to the anode at the factory continues to grow during sensor operation. However, this has no effect on the reaction taking place at the cathode.
