Endress+Hauser 11 Installation Stamolys CA71CL Adjusting the level monitoring You have to adjust conductive level monitoring depending on whether you want to connect one, two or three analyzers to this single collecting vessel. 1. Depending on the application, mount the right adjusting pin (→ å 8, → å 9, item 2) or do not use any adjusting pin. 2. Pull the marked pipe (item 3) downwards in accordance with your application (1, 2 or 3 analyzers) to set an optimum collecting volume. 1 1 2 2 3 3 a0001367 Fig. 8: 1 2 3 3.4 One analyzer M 3x12 M 3x35 (adjusting pin) Marking 1 1 3 a0001366 Fig. 9: 1 2 3 Two analyzers M 3x12 M 3x20 (adjusting pin) Marking 2 a0001365 Fig. 10: 1 3 Three analyzers M 3x12 Marking 3 Installation instructions To install the analyzer at the intended location, proceed as follows: 12 1. Mount the analyzer and secure it to a wall using screws (Ø6 mm / 0.24"). For the installation dimensions, please see the previous chapter. 2. Using a spirit level, check that the cabinet is hanging or standing straight. Only in this way can any air bubbles present escape from the cell. 3. Fit the edge covers (with GFR housing only). 4. Lay the drain pipe for the reaction products. Where possible, use solid pipes (PVC or PE, internal diameter 1" with 3% incline). 5. Insert the valve hoses accordingly. These were partly removed from the valves for transportation. This prevents the hoses from sticking or pressure being applied to a point in the hose over an extended period. → å 11 Endress+Hauser Stamolys CA71CL Installation 1 3 2 V3 V2 V1 6 7 5 a0006362 Fig. 11: Valves and valve hoses V1-2 Valves Channel switchover 1 To sample pump 2 Connecting hose to valve 1, at rear 3 4 5 6 7 Outlet hose Hose, valve 2 at front, standard Hose, valve 2 at rear, cleaner Hose, valve 1 at front, sample Secure the hose boxes in the appropriate pump holders (→ å 12): Sample pump left, reagent pump right.

Separate cable ducts are ideal. Cable run without loops and crossovers? Are power supply and signal lines connected correctly according to wiring diagram? Are all screw terminals tightened? Are all cable entries mounted, tightened and leaktight? Interference suppressor at the analog output? Current output simulation See procedure below Current output simulation: 1. Hold both arrow keys down (see "Display and operating elements" chapter) and connect the analyzer to the power supply. Wait until the display shows "0 mA". 2. At your PLC, PCS or data logger, check whether the same current value is applied. 3. Press the key. This allows you to browse to the next current values (4, 12, 20 mA, depending on the setting). 4. Check that the current values in question are also present at your PLC, PCS or data logger. 5. If the values are not present: a. Check the terminal assignment for analog output 1 or 2. F b. Disconnect the analog outputs from your PLC, DCS or data logger and repeat steps 1-4 but this time measure the current values at the terminals of the analyzer and not at the PLC, DSC or data logger.

Menu item Range of adjustment (factory settings in bold) Code number 03 Input 03. If an incorrect code is entered the program exits the sub-menu. Photometer Depending on specification CL-A CL-B CL-C CL-D The setting displays the parameter that is being measured. This is defined by the product specification and set in this menu item at the factory. Do not change the value. Otherwise, you will receive an "Incorrect photometer" error message. Default settings Yes / no If "yes" is selected, all the settings are reset to the factory settings. You must set the current date and time (scroll through the menu, third-last point). In the event of a reset, the date for the 1st calibration and the 1st flush is set to the following day. Measuring unit mg/l The measuring unit selected depends on the type of photometer. This setting also affects the scope of the measuring range. Calibration factor 0.10 to 10.00 The calibration factor is the ratio of the measured concentration of the calibration standard to the predefined concentration of the standard (see "PARAMETER ENTRY", calibration solution). The deviation results from factors such as reagent aging, aging of constructive components, etc. The calibration factor compensates for these effects. CA 71 checks the registered calibration factor logically. If the factor is outside of the error tolerance, the calibration is automatically repeated. If the value is still outside the tolerance range after repeating calibration, an error message appears and the analyzer continues to work with the most recently registered, logically correct factor. The last 100 calibration factors are stored in the memory with the date and time and can be retrieved by pressing the J key. The calibration factor can be changed manually. Optional dilution modules are taken into consideration in the calibration factor. Concentration offset 0.00 to 50.0 mg/l The offset gives users the option of adapting to an external comparison measurement. (Change the sign with the J key.) 0.10 to 10.00 1.00 If the sample is diluted externally between taking the sample and the analyzer, the dilution factor has to be entered here. If an optional dilution module is used, the factor remains 1. The dilution is taken into consideration by means of the calibration factor. 20 to 300 s 80 s Dosing time for sample or standard. During this time, the entire system is flushed with sample or standard, so when the reagent is added there is definitely only fresh sample in the mixer.

Take some of the sample out of the collecting vessel to determine the chlorine in the laboratory. 2. Make a note of the current measured value of the analyzer. 3. Perform the laboratory measurement simultaneously. 4. Calculate the calibration factor (= laboratory value: analyzer measured value). This value has to be entered at the analyzer. 5. Hold H down until AUTO MEASURING appears. 6. Use W to move through the CONFIGURATION menu and press F. 7. Use F to go to the "Calibration factor" item. 8. Select the item with F. 9. Enter the computed calibration factor with the aid of the W and V keys. 10. Press F to accept the value and then press H twice to return to the main menu. 11. Press F again. This takes you back to the measuring mode. The new calibration factor is accepted and the analyzer measured value and laboratory measured value must match. ! 30 Note! If the measured value and the laboratory value do not match after entering the factor, check the calculation and correct the factor entered, if necessary.

Check, in particular, that all hose connections are secure so that no leaks occur. • Ensure that the line voltage corresponds to the voltage specified on the nameplate. 6.2 Switching on 6.2.1 Dry commissioning Note! • If possible, let the analyzer warm up in standby mode before commissioning ("Auto measuring" display). The time can be defined via the "1. measurement" option in the PARAMETER ENTRY menu. • At the start of measurement with a cold analyzer, the first measuring results will be incorrect. The reaction is temperature-dependent and if the temperature is too low the predefined reaction time is insufficient for a complete reaction. For this reason, never carry out calibration with a cold analyzer. Wait at least two hours before carrying out calibration. When the analyzer has been configured and calibrated, the measuring cycle starts automatically. Configuration is no longer necessary. To perform initial commissioning or to readjust the device parameters, proceed as follows: 1. Plug in the analyzer's plug with grounding contact into the socket. 2. Press the H key until AUTO MEASURING is displayed. 3. Select the CONFIGURATION menu and configure up to and including the "Current date/time". With H you can return to the main menu. 4. Now work through the PARAMETER ENTRY and SERVICE menus. With H you can return to the main menu. 5. Select CONFIGURATION again and use F to go to the "Calibrate offset" menu item. 6. Connect a vessel containing distilled water to the "Sample" connection and start the frequency offset (J key). The value determined is displayed and saved. 7. Then reconnect the sample line. With H you can return to the main menu. The analyzer starts automatically (triggered by a control signal or integrated timer) with the "Calibration", "Measurement", and "Flushing" procedures in accordance with the device parameters that you have set (1st calibration, 1st measurement, 1st flushing times and the respective intervals control the procedure).

Proceed as follows: ! 1. Plug in the analyzer's plug with grounding contact into the socket. 2. Press the H key until AUTO MEASURING is displayed. 3. Select the SERVICE menu. 4. Switch the P2 reagent pump "on" (select P2 with F and set to "g" with V) and leave it running until you can tell that there are reagents at the T-hose connector. After this, switch P2 "off" (s) again with W. 5. Now switch the valves to passage for standard (select V1: S, V2: S; with F or K switch to "S" with V) and then switch the P1 sample pump "on". Leave the pump running until you can tell that there is standard at the T-hose connector. Switch P1 back "off". 6. Now switch the valves to passage for cleaning agent (select V1: S, V2: R; with F or K, switch to "R" or "S" with V) and then switch the P1 sample pump "on". Leave the pump running until you can tell that there is cleaning agent at the T-hose connector. Switch P1 back "off". 7. Now switch the valves to passage for sample (select V1: P, V2: S; with F or K, switch to "P" or "S" with V) and then switch the P1 sample pump "on". If you notice that sample is present at the T-hose connector, let the pump run for another 2 minutes. This removes any standard or cleaner residues. Then switch P1 "off". Note! For the two-channel version, valve V3 must also be set for switchover between channel 1 and channel 2. 8. Now proceed as with dry commissioning (from step 2). 6.2.3 Using a dilution module You can extend the measuring range of your analyzer with the sample dilution module. How it works: • The analyzer determines the absorption of the sample at the specified wavelength. It does not matter whether the sample was diluted previously or not. • The characteristic of the photometer (--> standard calibration data) refers to the concentrations of the diluted sample and not to those of the (undiluted) original sample. • The dilution factor is not taken into account until the measured value is calculated. • The concentration information you specify for the measuring range and the alarm values in PARAMETER ENTRY refer to the concentrations of the original sample. ! 32 Note! You achieve maximum measuring accuracy if you also dilute the standard with the dilution module. In the event of a 1:10 dilution, you have to use a 10 mg/l standard solution instead of a 1.0 mg/l standard solution (without a dilution module) for example. Balance changes to the dilution ratio (e.g. through hose aging) with the calibration. The calibration factor determined takes into account all deviations from the ideal state through reagents, the photometer and dilution. Endress+Hauser Stamolys CA71CL Commissioning Installing the dilution module The dilution module is supplied ready to use. Installation: " 1. Release the sample pump hose from the hose connector to valve 1 (→ å 20, item 4). 2. Connect the sample hose of the dilution module (black/black or yellow/blue, depending on the version) to the hose connector that is now free. 3. Connect the T-section (item 1) of the dilution module to the input of the sample pump (hose box K1). Use the original sample pump hose for this purpose. 4. Fit the dilution module onto the free hose box positions of the sample pump. 5. Connect an outflow hose (O) to the free outlet of the T-piece (item 1). Route this hose in the device in such a way that is guided at least 20 cm upwards and then into the open outlet. This prevents the hose from running dry. Caution! Do not connect the outflow hoses of the dilution module and the photometer. a0006622 Fig. 20: K1 K2 K3 A O P W 1 2 3 4 Endress+Hauser Dilution module Hose box of the original sample pump Hose box for additional sample (standard) Hose box for dilution water Sample supply to photometer Overflow (in outlet of analyzer) Sample hose (sample or standard) Dilution water inlet (to be provided by the client) T-section 3.2 x 3.2 x 3.2 mm (0.13 x 0.13 x 0.13 inch) Static mixer 122-012 T-section 3.2 x 3.2 x 3.2 mm (0.13 x 0.13 x 0.13 inch) Hose connector 3.2 x 1.6 mm (0.13 x 0.06 inch) 33 Commissioning Stamolys CA71CL Changing parameters !

You may not carry out any procedures not listed in the following chapters yourself. This work may only be carried out by Service. Note! At the end of any maintenance work, you must perform an F-offset measurement and a calibration. In this way, you adapt the analyzer to the altered conditions. 7.1 Maintenance schedule All the maintenance tasks that have to be carried out during normal operation of the analyzer are explained below. If you are using a sample conditioning unit, e.g. CAT430, coordinate the maintenance work required for it with that of the analyzer. For this, read the maintenance chapter in the Operating Instructions in question. Period of time Task Note Weekly – Check and note down the calibration factor (for service purposes) – Move the valve hoses and spray with silicon spray (extends the operating time). CONFIGURATION Every 2 weeks – Replace reagents and redetermine the calibration factor – see chapter "Replacing reagents" and CONFIGURATION – You must release the box of the sample pump for this purpose. Monthly – Flush sample line hose system with pressurized water (disposable injector), check and replace reagents if necessary. – Flush the sample line hose system with 12.5% bleaching lye (sodium hypochloride) and rinse thoroughly with water1) – see chapter "Replacing reagents" – You must release the box of the sample pump. – Connect the disposable injector instead of the sample supply. – SERVICE V1: S, P1: g, P2: s, V2: S Attach solution to sampling connection. # Warning! Caustic.Wear protective gloves and goggles. Beware of reagent splashing. – Spray pump hoses and roller heads with silicone spray – Check sample collector for fouling and clean it if necessary Every 3 months – Cleaning drain lines: Flush all hoses with 10% ammonia solution and then rinse with sample for 30 minutes at least – Rotate pump hoses Every 6 months – Replace pump hoses – Replace valve hoses 1) ! Endress+Hauser – see chapter "Replacing pump hoses" With standard cleaner for CA71SI-A Note! Prior to working on the reagent hoses, the hoses must be disconnected from the canisters in order to prevent contamination of the reagents. 35 Maintenance Stamolys CA71CL 7.2 # Replacing reagents Warning! • There is a danger of crushing at the door and pump heads. • Refer to the warning instructions in the safety data sheets when handling reagents. Wear protective clothing, gloves and goggles. • Make sure the workplace is well ventilated when you work with chlorine bleach and/or ammonia. If you feel unwell, consult a physician immediately. • If reagents come into contact with the skin or eyes, carefully rinse with copious amounts of water and consult a physician immediately. • Never add water to reagents. Reagents containing acids may splash and heat may build up. If you store the reagents correctly (in the dark, not over 20 °C) they will keep (unopened) for a minimum of 12 weeks from the date of production (batch number). When this period of time has expired, the reagents must be checked and replaced where necessary. A cool, dark storage area is required to achieve the maximum shelf life. The reagents must be replaced when: • The reagents have been contaminated by sample (see "Troubleshooting instructions") • The reagents are too old • The reagents have been spoilt by incorrect storage conditions or environmental influences. 7.2.1 Checking reagents 1. Produce a standard (1 mg/l Cl2). 2. Check the concentration of the standard in the laboratory. Adapt the values (PARAMETER ENTRY, calibration solution") or replace the standard solution. 3. Mix 10 ml standard solution and 5 ml of each reagent in a beaker. You must replace the reagents if there is no visible coloration after max. ten minutes. The finished mixture must be free of particles. The reagents must be replaced if no visual coloration (blue) occurs after max. 2 minutes or if the mixture is not free of particles. 7.2.2 1. Carefully remove the hoses from the canisters and wipe them with a dry (paper) towel. Wear protective gloves when doing this. 2. Switch on the reagent pump for about 5 seconds. 3. Flush the reagent hose with plenty of distilled water (see SERVICE). For this purpose, place a beaker with distilled water into the device. 4. Replace the reagent canisters and feed the hoses into the new canisters. 5. Fill the reagent hose with the new reagents (SERVICE). Switch all pumps to "g" for this purpose. Do not switch the pumps off ("s") until no more air bubbles are to be seen in the hoses. 6. Determine the reagent blank value by using deionized water as a sample (see "CONFIGURATION"). The value determined is saved by the analyzer as the frequency offset. 7. Then carry out a calibration (see chapter "Calibration"). 7.3 # Replacing reagents Replacing pump hoses Warning! When removing hoses from the hose nozzles, beware of reagent splashing. For this reason, wear protective clothing, gloves and goggles. The peristaltic pumps used for the analyzer convey the medium in a combination of vacuum and displacement pump. The pump rate is dependent on the elasticity of the pump hoses. Elasticity 36 Endress+Hauser Stamolys CA71CL Maintenance decreases and the pump rate drops as mechanical stress increases. Wear depends on mechanical stress (measuring interval, pump pressure). Up to a certain degree, the wear effect can be compensated by calibration. If the impairment in hose elasticity is too great, the pump rate is no longer reproducible and this leads to incorrect measurements. This is why it is necessary to replace the hoses. Removing the old hoses 1. Remove the reagent hoses from the reagent canisters in order to prevent contamination of the reagents. 2. Flush the old hoses with water first and then with air to empty them (see SERVICE). 3. Remove the hoses from the nipples of the hose boxes (→ å 21, item 5). 4. Release the hose box(es) (1 to 3 per pump): – Press against the lower retainer (item 3). – You can now remove the hose box along with the pump hose. – Remove the old hose from the case any dispose of it. – Clean the hose box and the roller head (item 1) with water. 1 2 5 3 1 2 3 4 5 Roller head Upper retainer of hose box Lower retainer of hose box Guide at pump hose Nipple with guide 4 a0001652 Fig. 21: Reagent pump Installing the new hoses 1. Fit the new hose on the hose box. 2. First pull the hose downwards at both ends and then push the guide on the hose into that of the nipple on the hose box. Make sure it is seated correctly. 3. First place the hose box into the upper retainer (item 2) of the pump and then press the case into the lower retainer (item 3). Make sure the hose boxes are in the correct order in the pump (→ å 22).

Reconnect the reagent hoses to the canisters. 6. After installation, refill the hoses with sample, standard or cleaner (SERVICE)1). 7. Determine the frequency offset (CONFIGURATION) and carry out calibration ("Calibration"). Caution! Make sure you connect the new pump hoses to the correct connections at the T-hose connector. For the order numbers of the pump hoses, see the chapter "Troubleshooting"/"Spare parts". Setting the contact pressure of the pump If the pump hoses cannot be filled free of bubbles, adjust the adjuster screw for the contact pressure of the pump: 1. Release the adjuster screw (→ å 23, item 3) to the extent that no more sample is pumped. 2. Tighten the screw just to the point that sample is pumped. 3. Tighten the screw another complete rotation. 3 a0001651 Fig. 23: 3 " Sample pump Adjuster screw for the contact pressure Caution! Adjust the contact pressure of the reagent hoses so that no sample is pumped into the reagent. Otherwise the reagent becomes immediately unusable. For this reason, only perform tests with distilled water. 7.4 Replacing valve hoses To replace the hoses, proceed as follows: 1. Flush the old hoses with water first and then with air to empty them (see SERVICE). 2. Remove the hoses from the valves: a. You can disconnect the front hoses directly because the valves are open when de-energized b. To remove the back hoses, press the black button on the valve and disconnect the hoses. 1) 38 3. Spray the new hoses and valves with silicone spray before inserting them. 4. Reverse the sequence of operations to install the new hoses. Ensure that the hoses are connected correctly (→ å 24). 5. After installation, refill the hoses with sample, standard or cleaning agent (SERVICE). 6. Determine the frequency offset (CONFIGURATION) and carry out calibration ("Calibration"). Make sure that the hoses are bubble-free when filled. If not, check the sample flow rate (see below).
