• Drinking water

• Water treatment

• Cooling water

• Gas scrubbers

• Reverse osmosis

• Food processing

• Swimming pool and bathing pool water.

Any other use than the one described here compromises the safety of persons and the entire measuring system and is, therefore, not permitted. The manufacturer is not liable for damage caused by improper or non-designated use.

1.3 Workplace safety

As the user, you are responsible for complying with the following safety conditions:

• Regulations for explosion protection

• Installation instructions

• Local standards and regulations

1.4 Operational safety

‣

Before commissioning the entire measuring point, make sure all the connections are correct. Ensure that electrical cables and hose connections are not damaged.

‣ Do not operate damaged products, and safeguard them to ensure that they are not

operated inadvertently. Mark the damaged product as defective.

‣ If faults cannot be rectified, the products must be taken out of service and secured against

unintentional commissioning.

Connection of the sensors 963

The sensor 963 is supplied without temperature sensor ex factory. Connect the sensor to the transmitter as follows:

• Without temperature measurement: Connect the supplied resistor10 k to the terminals 11 and 12. The measured value display will constantly indicate 25 °C (77 °F).

• With temperature measurement: Install the NTC temperature sensor10 k / 25 °C (77 °F) (120 mm installation version TSP

3692) into the sensor 963. Use the measuring cable CPK1 to connect the temperature sensor to the terminals 11 and 12 of the transmitter.

• Chlorine sensor: Connect the red wire to terminal 92 (cathode) and the blue wire to the terminal 91 (anode).

Connection of pH or ORP sensors

Connect the pH or ORP sensor always symmetrically to prevent a mutual interference of several sensors mounted in the CCA250 assembly. Symmetrical connection requires a potential matching pin. It is integrated as standard in the CCA250 flow assembly and is connected to the PA/PM terminal by a potential matching line.

If you are using glass electrodes with the panel-mounted instrument, you have to terminate the measuring cable with a BNC connector. A solder-free BNC connector is supplied with the device. Proceed as follows:

1. Cut off end sleeves 2 and 3 of the coaxial cable ( å 16).

1Coaxial cable 2 Inner screen BK (ref.) 3 Inner coax (pH/mV) 4Strand BN (PA)

2. Push the cable gland 5 and the washer 6 onto the coaxial cable.

3. Remove the insulation (13 mm(0.51")) and screw the clamping ring 7 onto the insulation.

Parts 5 to 7 are supplied with the BNC connector for cable diameters 3.2 mm (0.13") and 5 mm (0.20").

4. Fold the braided screen 8 over the clamping ring and cut off the excess material.

5. There is a semi-conductor layer 14 (conductive foil) between the inner insulation and the braided screen 8. Strip this semi-conductor layer to the braided screen.

• Operation of the relay in manual mode

In measuring mode, you get the following sequence of functions by repeatedly pressing the PLUS key:

1. Temperature display in °F

2. Temperature display hidden

3. pH measuring value or ORP potential (only on EP version)

4. pH sensor signal in mV (only on EP version)

5. Measured value display of Cl

/ ClO2 in nA

6. Zero current of the sensor CCS120

7. Measured value display of current input in %

8. Measured value display of current input in mA

9. Return to basic settings

In measuring mode, the following is displayed in sequence by

repeatedly pressing the MINUS key:

1. Current errors are displayed in rotation (max. 10).

2. Once all errors have been displayed, the standard measurement

display appears. In the function group F, an alarm can be defined separately for each error code.
