Operating the Analyzer 5.9 Cation Calc Display 5.9.1 Overview This group allows you to configure dual conductivity inputs for cation or degassed CO2 measurement. The cation selection of Ammonia or Amines will display a calculated pH value from differential conductivity and provide continuous pH monitoring using reliable, maintenance free conductivity cells. An outline of the conductivity cells’ installation is illustrated in Figure 5-6.
Operating the Analyzer Degassed CO2 The dual input UDA can also be configured for degassed CO2 measurement by employing cells #2 and #3. Here the cation effluent stream is degassed of CO2, typically by heating the cation effluent stream to a near boiling temperature. This heating step results in CO2 out-gassing. The resulting 25°C compensated conductivity measurement of Cell #3 is lower in value in proportion to the amount of dissolved CO2. 5.9.
Operating the Analyzer Note: The relationship between the electrolytic conductivity and the pH of ammonia and amines is well established in the technical literature. It must be understood that the UDA was designed for accurate results over the pH range of 8 to 10.5 based on ammonia or amine chemistries. Other chemistries such as phosphate or systems that employ alternative anions, such as borate, cannot be expected to realize results with similar accuracy.
Operating the Analyzer 5.9.7 Troubleshooting In normal operation, both the direct electrode pH measurement and the pH from differential conductivity should very closely match each other. If they DO NOT match each other, the possible causes are listed below: 1. Upsets in water chemistry, such as cation exchange resin exhaustion, can cause the pH readings to not agree with each other.

Input Calibration 8.6.3 ORP Calibration Using Voltage Input Calibrates Analyzer only The procedure described in this sub-section calibrates the Analyzer only. It does not involve compensating for electrode drift. Instead, a known millivolt signal is applied to the analyzer input terminals in place of the signal from the electrode, and the UDA2182 is adjusted so that its reading matches the known input.
Input Calibration Step Action Screen 4 Insert a screwdriver into the tab in the terminal board to be wired and pull. Slide the board half way out. There is a notch in the terminal board into which you can slide the retainer tabs and hold the boards in place while wiring. 5 Label and remove the input wiring from the input terminals.

Input Calibration 8.7 Conductivity Calibration 8.7.1 Introduction Each type of cell has an associated cell constant entered during Configuration setup (see Section 6.6). This number is part of the cell model number. However, for greater precision, every Honeywell cell is individually tested at the factory, and a calibration factor unique to that cell is determined. The cal factor for a cell can be found on the plastic tag hanging from the cell lead wires.
Input Calibration 8.7.4 Determining TDS conversion factor To determine the TDS conversion factor, it is first necessary to establish the total dissolved solids in a representative sample of the process. The formal determination of TDS is a laboratory standard method performed on a weighed grab sample of the process fluid. To summarize how to obtain a TDS value: • Suspended solids, if present, are filtered out. • All water is evaporated. • The residue is dried and weighed.
Input Calibration 8.7.5 Performing Calibration Trim Introduction For most applications entering the cal factor for each cell will achieve satisfactory system performance. However, it is possible to perform a calibration trim procedure in which the Analyzer and cell combination are used to measure a reference solution of known conductivity; the reading of the Analyzer is adjusted to match.

Input Calibration 8.8 Dissolved Oxygen Calibration Overview The analyzer supports three methods of Dissolved Oxygen calibration: Air Calibration - is done with the probe removed from the process. This is the recommended method of calibration and should be completed unless the process set-up prohibits removing the probe. This is recommended prior to installation as it saves system parameters that are used in optimizing error diagnostics.
Input Calibration Calibrating a Dissolved Oxygen Probe Using Air Calibration Method Introduction This is the simplest and most commonly used method of calibration. ATTENTION If “Initial Installation”, power probe and analyzer for 24 hours before first air calibration. 1. Assure that the probe has been powered for at least one hour. 2.

Input Calibration Calibrating the Integral Pressure Sensor Introduction The concentration of oxygen dissolved in air-saturated water depends on the barometric pressure. This dependence is automatically compensated for during air calibration using a pressure sensor built into the Analyzer. The purpose of the pressure calibration is to calibrate that pressure sensor. However, this sensor has been factory calibrated and should not require re-calibration.

Input Calibration before the test was initiated. During this voltage sweep, the probe current is monitored and the graph of current as a function of voltage is displayed. If during the test the probe current rises above a factory-set upper limit, the bias voltage is returned to its pre-test value at 25mV/sec and the test is terminated without completing the full 1.0 Volt sweep. (The bias voltage test may also be terminated at any time by pressing the “EXIT” button.
Input Calibration exceeding 0.8 volts, a second process (water reduction) begins to occur and the current again rises. To achieve stable results, the probe should be operated within the flat region so that small changes in the probe characteristics result in negligible changes in probe current.

Appendices 15.2 Appendix A – Entering Values for Lead Resistance Compensation (See Appendix B for titanium cells mounted into stainless steel flow chamber 31079198) Introduction If you use standard Honeywell cell lead lengths of 7 or 20 feet connected directly to the Analyzer, no compensation for lead resistance is necessary. Similarly, if a junction box is used to extend the leads up to 150 feet, no compensation is required.
Appendices Since the analyzer only allows entry of one wire gauge type, we allow for the worst-case condition by dividing the total resistance by the resistance per thousand feet of the higher resistance gauge wire. In our example this would be: 4.0 ohms ÷ 6.4 ohms per thousand feet of 18 AWG wire = 625 feet Therefore, in our example we would use the procedure in Table 6-5, and specify the wire gauge as 18 AWG and the length as 625 feet.
Appendices 15.3 Appendix B – Entering Values for Lead Resistance Compensation [Titanium Cells] (4973 or DL4311 Titanium cells mounted in stainless steel flow chamber 31079198) Introduction If you use standard Honeywell cell lead lengths of 7 or 20 feet connected directly to the Analyzer, no compensation for lead resistance is necessary. Similarly, if a junction box is used to extend the leads up to 150 feet, no compensation is required.
Appendices Because there are two different types of wire used in each lead to the cell in this example, the total lead resistance is calculated as follows: (Note: the analyzer accounts for the fact that there is always a pair of conductor wires in the system loop.) (0.5 x 6.4) + (0.2 x 10.2) = 5.24 ohms Since the analyzer only allows entry of one wire gauge type, we allow for the worst-case condition by dividing the total resistance by the resistance per thousand feet of the higher resistance gauge wire.
Appendices 15.4 Appendix C - Cyanide Waste Treatment Introduction Uses of cyanide solutions Cyanide solutions are used in plating baths for zinc, cadmium, copper, brass, silver and gold. The toxic rinse waters and dumps from these operations require destruction of the cyanide (typically to a level below 0.1 ppm) before its discharge. Technique for cyanide destruction The technique most often used for cyanide destruction is a one or two-stage chemical treatment process.
Appendices First Stage of Cyanide Destruction Raise pH and oxidize cyanide Sodium hydroxide (caustic) is used to raise the effluent to about 11 pH, which will promote the oxidation reaction and ensure complete treatment. The oxidizing agent is usually sodium hypochlorite, NaOCl. The reaction for the first stage is given below using the NaOCl and with cyanide expressed in ionic form (CN- ). The result is sodium cyanate (NaCNO) and chloride ion (Cl- ).
Appendices Importance of pH control As shown in Figure 15-4, pH has a direct effect on the ORP potential and must be closely controlled to achieve consistent ORP control, especially if hypochlorite is used as the oxidizing agent. Hypochlorite raises pH, which lowers the ORP potential, which in turn calls for additional hypochlorite -- a runaway situation. To avoid this situation, use close pH control and locate the ORP electrode at a distance from the hypochlorite addition point.
Appendices Batch Treatment Sequence of steps Continuous treatment is shown in Figure 15-3. However, all of the reactions can be achieved with semi-automatic batch control. Only a single tank with a pH controller and an ORP controller are required. The steps are sequenced, and the pH and ORP setpoints are changed to give the same results as for the continuous treatment.
Appendices 15.5 Appendix D – Chrome Waste Treatment Use of Chromates Corrosion inhibition Chromates are used as corrosion inhibitors in cooling towers and in metal-finishing operations including bright dip, conversion coating, and chrome plating. Necessity for removal of chromium ion from wastewater The wastewater form rinse tanks, dumps, and cooling tower blowdown contains toxic soluble chromium ion, Cr+6, which must be removed, typically to a level less than 0.5 ppm before discharge.
Appendices First Stage of Chrome Removal Lower pH and add reducing agent Sulfuric acid is used to lower the pH to about 2.5, which promotes the reduction reaction and ensures complete treatment. The reducing agent may be sulfur dioxide, sodium sulfite, sodium bisulfite, sodium metabisulfite, sodium hydrosulfite, or ferrous sulfate. The reaction is given below.
Appendices Chrome reduction is slow enough that 10 to 15 minutes may be required for a complete reaction and this time increases if pH is controlled at higher levels. The pH also has a direct effect on the ORP potential as shown in Figure 15-6. Therefore, pH must be controlled to achieve consistent ORP control. Second Stage of Chrome Removal Neutralize the wastewater In this stage the wastewater is neutralized to precipitate the Cr+3 as insoluble chromium hydroxide, Cr(OH)3.
Appendices negative. The chromium, an oxidizing ion, Cr+6, accepts electrons and makes the electrode more positive. The net electrode potential is related to the ratio of concentrations of reducing and oxidizing ions in the solution. Potential cannot be used as monitor of effluent This electrode potential is extremely sensitive in measuring the degree of chrome treatment in the reaction tank.
Appendices 15.6 Appendix E – Two-cell Applications Ion Exchange Ion exchange operations can achieve especially precise control using the conductivity ratio of two points with each bed. Ratio measurement accounts for feedwater variations when the upstream point is measured at the cation bed inlet. With the upstream point in the bed as shown for following stages, it can identify exhaustion before breakthrough.
Appendices alarms (+ and -) are used. A difference kind of diagnostic can be provided by a precision check resistor in place of one cell to give continuous Analyzer/Controller checking at one value. Also see 15.11 Appendix J – Discussion on Chemical Interferences on Measured DO Currents.
Appendices Softener Monitor Softener monitoring by conductivity ratio gives a continuous indication of performance. Sodium is typically more conductive than the hardness minerals it displaces, yielding a higher conductivity at the outlet. A ratio approaching 1 indicates that hardness ions are breaking through and that regeneration is needed. (HARD) WATER SUPPLY CELL 2 CELL 1 Softening Ratio = Cell1 Cell2 (SOFT) TREATED WATER Typical Ratio Range is 1 to 1.

Appendices 15.7 Appendix F – Using a Precision Check Resistor (For Conductivity) Introduction The operation of the Analyzer/Controller can be verified by replacing the input from a cell with a precision check resistor across the Analyzer/Controller input terminals. In addition, an 8550 ohm resistor (Honeywell Part No. 31233300) can be wired in place of the inputs from the temperature compensator to simulate 25º C, the reference temperature.
Appendices Example 1: To determine the check resistor value needed to simulate conductivity measurement of 10 μS, use cell constant 0.1 and perform the following calculation: 10 k ohms = (0.1) x (1,000,000) 10 Example 2: To determine the check resistor value needed to simulate resistivity measurement of 10 M ohms, use cell constant 0.01 and perform the following calculation: 100 K ohms = (0.01) x (10,000,000) Concentration values Obtain the appropriate check resistance value from the table below.
Appendices 15.8 Appendix G – Noise Testing, Dissolved Oxygen Application Hints for Reducing Noise Specifications for proper operation of Honeywell dissolved oxygen (DO) probes demand that the alternating current (AC) voltage signal (noise) between anode and shield connections and cathode and shield connections be less than 1 mV AC.
Appendices 15.9 Appendix H – DO Probe and Analyzer Tests Before performing air leak detection, it is necessary to determine that both Probe and Analyzer are working properly. Assumptions: • The probe and analyzer should be connected, the analyzer powered-up, and the probe in the process water for at least 24 hours prior to testing. • No additional configuration should be done. • The process is as it would be normally. All equipment in the process is online and contributing to the process.
Appendices Check that analyzer is working 1. Remove power from analyzer. 2. Disconnect the probe and put the following resistor values on the terminal block of the analyzer: • Jumper (bare wire) - Anode(8) to Ref(9) • 10k resistor - Ref(9) to Cathode(10) • 5k resistor across thermistor leads - 4 and 5 3. Turn analyzer back on. 4. If you see a reading of between 5 and 10 ppm or 5000 and 10000 ppb at 25°C, the analyzer is working correctly. 5. If not, the analyzer maybe the problem.
Appendices problem is that the cursor is positioned too far to the left or right of the flat portion of the curve, move the cursor back to the flat portion of the curve. 15. Perform another Air Calibration to correct any changes that occurred during the PBT. 16. If you reached this point, you have both a working probe and analyzer that are calibrated to one another correctly.
Appendices 15.10 Appendix I – Parameters Affecting Dissolved Oxygen Measurement The actual quantity of oxygen that can be present in solution is governed by the partial pressure of the gas in the atmosphere, the solubility in solution, the temperature and purity of the solution. Pressure UDA2182 Universal Dual Analyzers include an internal pressure sensor and software algorithm that automatically compensates for atmospheric pressure variations during calibration.
Appendices 15.11 Appendix J – Discussion on Chemical Interferences on Measured DO Currents There are four contributors to measured current: Faradaic Currents Faradaic currents are those resulting from oxidation or reduction of chemical species. The reduction of oxygen to water, the oxidation of water to oxygen, and the oxidation of hydrogen, hydrazine or sulfur dioxide, are examples of Faradaic currents.
Appendices Faradaic Interferences The DO probe responds to oxygen partial pressure as follows: O2 + 4H+ + 4e- → 2H2O (1) Reaction (1) is a chemical reduction in which dissolved oxygen is reduced to water. This reduction occurs at the working electrode, commonly referred to as the cathode. The equal and opposite (oxidation) reaction occurs at the counter electrode (anode).
Appendices 15.12 Appendix K – Percent Saturation Readout In some special applications, it is desirable to read out in percent saturation rather than concentration. These are usually in nonaqueous solutions where the normal temperature compensation of the Series UDA2182 Analyzer for the solubility of air/oxygen in water does not apply. The percent saturation readout disables this solubility part of the temperature compensation.
Appendices 15.13 Appendix L – Leak Detection in PPB Applications Before performing air leak detection, it is necessary to determine that both the probe and analyzer are working properly. Refer to Probe and Analyzers tests in Section 15.9 1. First, check to see that the probe contains an O-ring. Per the probe directions, an Oring must go into a probe that is used in ppb applications. This creates a tight seal between the probe and flow chamber. MAKE SURE THIS O-RING IS IN THE PROBE. 2.
Appendices 15.14 Appendix M – Procedure for Low Level ppb Dissolved Oxygen Testing Overview The purpose of this procedure is two-fold. First, using a controlled environment, new probes and/or analyzers can be tested to determine if each is performing correctly before being installed in the field. Second, this procedure can be used to re-test the performance of an existing analyzer and/or probe. You may choose to use this set-up for a zero calibration test.
Appendices 9. Return probe to flow chamber and resume nitrogen sparging. 10. When analyzer indicates that DO level is below 20 ppb, change gas to 250 ppm O2 in nitrogen. Run until equilibrated (4-6 hours). After equalization, note barometric pressure and temperature. 11. Compare reading with calculated value. To Calculate True Value *Air Sat. Value at T °C x known gas O2 Value x Barometric Pressure = True Value 20.
Appendices 15.15 Appendix N – Sample Tap Electrode Mounting Recommendations Overview Many applications tap a sample from a main process stream and, after the flow has passed through the measurement manifold, it is discharged to a sink or floor drain. Typical Probe Installation A typical probe installation will find the probe mounted in a flow chamber or tee arrangement similar to what is shown in Figure 15-8.
Appendices then the pressure at the sensor is four feet water-column below atmospheric pressure. Any fitting leaks at or beyond the flow adjustment valve will result in air infiltration into the sample. This entrapped air can result in noisy and unstable measurement. In the case of a part per billion dissolved oxygen (DO) measurement, the indicated DO value can be substantially higher than the true value.
Appendices 15.16 Appendix O – Auto Clean and Auto Cal Examples Automatic Cleaning and Calibration Overview Although the Honeywell probe accuracy is unaffected by inert fouling, there are two conditions where probe cleaning may be required. (These conditions affect all conventional dissolved oxygen probes as well.) The first is where the fouling is so thick that the response time of the probe becomes unacceptably long.
Appendices Figure 15-9 Auto Clean Setup 232 UDA2182 Universal Dual Analyzer Product Manual January 2009
Appendices Automatic Calibration of ppb Dissolved Oxygen Probe A typical set – up for automatic calibration in a boiler water sampling system is shown in Figure 15-10. The solenoid valve and connections should be supplied by others and must be positively air tight to prevent leakage and erroneous measurements. The solenoid valve is wired to assigned relay contacts in the UDA2182 analyzer and will operate at a frequency, and for duration as assigned by the end user.
Index 15.17 Appendix P – AutoClean and AutoCal Theory and Piping Overview Periodic calibration of pH electrodes is necessary for best system performance because electrode outputs change over time. One-point calibration (standardization) is a zero adjustment to compensate for electrode drift. Two-point calibration (standardization and slope adjustment) includes a span adjustment to match the gain of the Analyzer/Controller to the electrode response.

Be sure that valves and fittings (S1) have sufficient pressure ratings to withstand pressure peaks which will occur when process flow is blocked.
Index divert the discharge to drain. 3 Relay 2 activates solenoid valve S2 for the preset buffer time (1 to 1999 seconds) to direct buffer solution past the electrodes by gravity. 4 After a stable reading is reached or the set maximum buffer time elapses, the 9782 stores the new calibration value using automatic buffer recognition. Diagnostics detect excessive instability or offset, prevent erroneous calibrating and can activate an alarm, depending on configuration.
Select piping and valves based on chemical resistance and pressure ratings Make the process connections as shown in Figure 15-12 or Figure 15-13. Materials and components should be carefully selected for chemical resistance to process and buffer solutions at anticipated temperatures. Be sure that valves and fittings have sufficient pressure ratings to withstand pressure peaks which will occur when process flow is blocked.
