DESCRIPTION AND SPECIFICATIONS • MULTI­PARAMETER INSTRUMENT – single or dual input. Choose from pH/ORP/ISE, Resistivity/Conductivity, % Concentration, Chlorine, Oxygen, Ozone, Temperature, Turbidity, Flow, and 4­20mA Current Input. • LARGE DISPLAY – large easy­to­read process measurements. • EASY TO INSTALL – modular boards, removable connectors, easy to wire power, sensors, and outputs. • INTUITIVE MENU SCREENS with advanced diagnostics and help screens. • SEVEN LANGUAGES included: English, French, German, Italian, Spanish, Portuguese, and Chinese. • HART® AND PROFIBUS® DP Digital Communications options FEATURES AND APPLICATIONS The 1056 dual­input analyzer offers single or dual sen­ sor input with an unrestricted choice of dual measure­ ments. This multi­parameter instrument offers a wide range of measurement choices supporting most indus­ trial, commercial, and municipal applications. The modular design allows signal input boards to be field replaced making configuration changes easy. Conveniently, live process values are always displayed during programming and calibration routines. QUICK START PROGRAMMING: Exclusive Quick Start screens appear the first time the 1056 is pow­ ered. The instrument auto­recognizes each measure­ ment board and prompts the user to configure each sensor loop in a few quick steps for immediate deploy­ ment. DIGITAL COMMUNICATIONS: HART and Profibus DP digital communications are available. The 1056 HART units communicate with the Model 375 HART® hand­held communicator and HART hosts, such as AMS Intelligent Device Manager. Model 1056 Profibus units are fully compatible with Profibus DP networks and Class 1 or Class 2 masters. HART and Profibus DP configured units will support any single or dual measurement configuration of Model 1056. MENUS: Menu screens for calibrating and programming are simple and intuitive. Plain language prompts and help screens guide the user through these procedures. DUAL SENSOR INPUT AND OUTPUT: The 1056 accepts single or dual sensor input. Standard 0/4­ 20 mA current outputs can be programmed to correspond to any measurement or temperature. ENCLOSURE: The instrument fits standard ½ DIN panel cutouts. The versatile enclosure design supports panel­mount, pipe­mount, and surface/wall­mount installations. ISOLATED INPUTS: Inputs are isolated from other signal sources and earth ground. This ensures clean signal inputs for single and dual input configurations. For dual input configurations, isolation allows any combination of measurements and signal inputs with­ out cross­talk or signal interference. TEMPERATURE: Most measurements require tem­ perature compensation. The 1056 will automatically recognize Pt100, Pt1000 or 22k NTC RTDs built into the sensor. SECURITY ACCESS CODES: Two levels of security access are available. Program one access code for routine calibration and hold of current outputs; program another access code for all menus and functions. 1 MODEL 1056 SECTION 1.0 DESCRIPTION AND SPECIFICATIONS DIAGNOSTICS: The analyzer continuously monitors itself and the sensor(s) for problematic conditions. The display flashes Fault and/or Warning when these conditions occur.

Used: 60Hz Information about each condition is quickly accessible by pressing DIAG on the keypad. User help screens are displayed for most fault and warning conditions to assist in troubleshooting. DISPLAY: The high­contrast LCD provides live measurement readouts in large digits and shows up to four additional process variables or diagnostic parameters. The display is back­lit and the format can be customized to meet user requirements. LOCAL LANGUAGES : Rosemount Analytical extends its worldwide reach by offering seven local languages – English, French, German, Italian, Spanish, Portuguese, and Chinese. Every unit includes user programming menus; calibration routines; faults and warnings; and user help screens in all seven languages. The displayed language can be easily set and changed using the menus. CURRENT OUTPUTS: Two 4­20 mA or 0­20 mA current outputs are electrically isolated. Outputs are fully scalable and can be programmed to linear or logarithmic modes. Output dampening can be enabled with time constants from 0 to 999 seconds. Output 1 includes digital signal 4­20 mA superimposed HART (option ­HT only) 2 SPECIAL MEASUREMENTS: The Model 1056 offers measuring capabilities for many applications. l Single or Dual Turbidity: Ideal in municipal appli­ cations for measurement of low­NTU filtered drinking water. Must be used with Clarity II sensor, sensor cable and debubbler. Model T1056 Clarity® II Turbidimeter System l 4­Electrode Conductivity: The 1056 is compatible with Rosemount Analytical 4­electrode Model 410VP in the PUR­SENSE family of conductivity sensors. This sensor supports a wide array of applications and is capable of measuring a large range of conductivity with one geometric configuration. Wired to the 1056, this sensor can measure 2μS/cm to 300mS/cm with an accuracy of 4% of reading throughout the entire range. l 4­20mA Current Input: Accepts any analog current input from an external device for temperature compen­ sation of measurements and atmospheric pressure input for partial pressure correction of oxygen. l Selective Ions: The analyzer is able to measure ammonia and fluoride using commercially available ion­selective electrodes. All analyzers with installed pH boards can be programmed to measure selective ions. l pH Independent Free Chlorine: With Rosemount Analytical’s 498Cl­01 sensor, the analyzer is able to measure free chlorine with automatic correction for process pH without the need for a pH sensor. l Inferential pH: The analyzer is able to derive and display inferred pH (pHCalc) using two contacting con­ ductivity signal boards and the appropriate contacting conductivity sensors. This method will calculate the pH of condensate and boiler water from conductivity and cation conductivity measurements. l Differential Conductivity: Dual input conductivity configurations can measure differential conductivity. The analyzer can be programmed to display dual conductivity as ratio, % rejection, or % passage. MODEL 1056 SECTION 1.0 DESCRIPTION AND SPECIFICATIONS SPECIFICATIONS ­ General Enclosure: Polycarbonate.

Typical uses are for temperature compensation of live meas­ urements (except ORP, turbidity and flow) and for continuous atmospheric pressure input for determina­ tion of partial pressure, needed for compensation of live dissolved oxygen measurements. External input of atmospheric pressure for DO measurement allows continuous partial pressure compensation while the Model 1056 enclosure is completely sealed. (The pressure transducer component on the DO board can only be used for calibration when the case is open to atmosphere.) Externally sourced current input is also useful for calibration of new or existing sensors that require temperature measurement or atmospheric pressure inputs (DO only). For externally sourced temp or pressure compensation, the user must program the 1056 to input the 4­20mA current signal from the external device. In addition to live continuous compensation of live measurements, the current input board can also be used simply to display the measured temperature. or the calculated partial pressure from the external device. This feature leverages the large display variables on the Model 1056 as a convenience for technicians. Temperature can be displayed in degrees C or degrees F. Partial pressure can be displayed in inches Hg, mm Hg, atm (atmospheres), kPa (kiloPascals), bar or mbar. The current input board can be used with devices that do not actively power their 4­20mA output signals. The Model 1056 actively powers to the + and – lines of the current input board to enable current input from a 4­20mA output device. Note: this Model 1056 signal input board (­23, ­33 model option code) also includes flow measurement functionality. The signal board, however, must be configured to measure either mA current input or flow.

It includes removable connectors and slide­out signal input boards. The front panel is hinged at the bottom. The panel swings down for easy access to the wiring locations. 3.1.1. Removable connectors and signal input boards Model 1056 uses removable signal input boards and communication boards for ease of wiring and instal­ lation. Each of the signal input boards can be partially or completely removed from the enclosure for wiring. The Model 1056 has three slots for placement of up to two signal input boards and one communication board. Slot 1­Left Slot 2 – Center Slot 3 – Right Comm. board Input Board 1 Input Board 2 3.1.2. Signal Input boards Slots 2 and 3 are for signal input measurement boards. Wire the sensor leads to the measurement board following the lead locations marked on the board. After wiring the sensor leads to the signal board, carefully slide the wired board fully into the enclosure slot and take up the excess sensor cable through the cable gland. Tighten the cable gland nut to secure the cable and ensure a sealed enclosure. 3.1.3. Digital Communication boards HART and Profibus DP communication boards will be available in the future as options for Model 1056 digital communication with a host. The HART board supports Bell 202 digital communications over an analog 4­20mA current output. Profibus DP is an open communications protocol which operates over a dedicated digital line to the host. 3.1.4 Alarm relays Four alarm relays are supplied with the switching power supply (85 to 265VAC, ­03 order code) and the 24VDC power supply (20­30VDC, ­02 order code). All relays can be used for process measurement(s) or temperature. Any relay can be configured as a fault alarm instead of a process alarm. Each relay can be configured independently and each can be programmed as an interval timer, typically used to activate pumps or control valves. As process alarms, alarm logic (high or low activation or USP*) and deadband are user­programmable. Customer­defined failsafe operation is supported as a programmable menu function to allow all relays to be energized or not­energized as a default condition upon powering the analyzer. The USP* alarm can be programmed to activate when the conductivity is within a user­selectable percentage of the limit. USP alarming is available only when a contacting conductivity measurement board is installed. 3.2 PREPARING CONDUIT OPENINGS There are six conduit openings in all configurations of Model 1056. (Note that four of the openings will be fitted with plugs upon shipment.) Conduit openings accept 1/2­inch conduit fittings or PG13.5 cable glands. To keep the case watertight, block unused openings with NEMA 4X or IP65 conduit plugs. NOTE: Use watertight fittings and hubs that comply with your requirements. Connect the conduit hub to the conduit before attaching the fitting to the analyzer. 19 MODEL 1056 SECTION 3.0 WIRING 3.3 PREPARING SENSOR CABLE The 1056 is intended for use with all Rosemount Analytical sensors.

The Model 1056 performs temperature compensation automatically by applying internal temperature correction algorithms. Temperature correction can also be turned off. If tem­ perature correction is off, the Model 1056 uses the tem­ perature entered by the user in all temperature correc­ tion calculations. 5.3.2 Procedure. Follow the menu screens in Fig. 5.1 to select automatic or manual temp compensation, set the manual reference temperature, and to program temperature units as °C or °F.

Choosing Temp Units and Manual Auto Temp Compensation 5.4 CONFIGURING AND RANGING THE CURRENT OUTPUTS 5.4.1 Purpose The Model 1056 accepts inputs from two sensors and has two analog current outputs. Ranging the outputs means assigning values to the low (0 or 4 mA) and high (20 mA) outputs. This section provides a guide for configuring and ranging the outputs. ALWAYS CONFIGURE THE OUTPUTS FIRST. 5.4.2 Definitions 1. CURRENT OUTPUTS. The analyzer provides a con­ tinuous output current (4­20 mA or 0­20 mA) directly proportional to the process variable or temperature. 32 The low and high current outputs can be set to any value. 2. ASSIGNING OUTPUTS. Assign a measurement to Output 1 or Output 2. 3. DAMPEN. Output dampening smooths out noisy readings. It also increases the response time of the output. Output dampening does not affect the response time of the display. 4. MODE. The current output can be made directly proportional to the displayed value (linear mode) or directly proportional to the common logarithm of the displayed value (log mode). MODEL 1056 SECTION 5.0 PROGRAMMING THE ANALYZER ­ BASICS 5.4.3 Procedure: Configure Outputs. Under the Program/Outputs menu, the adjacent screen will appear to allow configuration of the outputs. Follow the menu screens in Fig. 5­2 to configure the outputs.

The security codes prevent accidental or unwanted changes to program settings, displays, and calibration. Model 1056 has two levels of security code to control access and use of the instrument to different types of users. The two levels of security are: ­ All: This is the Supervisory security level. It allows access to all menu functions, including Programming, Calibration, Hold and Display. ­ Calibration/Hold: This is the operator or technician level menu. It allows access to only calibration and Hold of the current outputs. 5.5.2 Procedure. 1. Press MENU. The main menu screen appears. Choose Program. Scroll down to Security. Select Security. The security entry screen appears. Enter a three digit security code for each of the desired security levels. The security code takes effect two minutes after the last key stroke. Record the security code(s) for future access and communication to operators or techni­ cians as needed. 4. The display returns to the security menu screen. Press EXIT to return to the previous screen. To return to the main display, press MENU followed by EXIT. Fig. 5­3 displays the security code screens. Program MAIN MENU Figure 5­3.

This allows operators or technicians to perform routine maintenance. This security level does not allow access to the Program or Display menus. When entering the correct access code for All security level, the user has access to all menu functions, includ­ ing Programming, Calibration, Hold and Display. 5.7.1 Purpose The analyzer output is always proportional to measured value. To prevent improper operation of systems or pumps that are controlled directly by the current output, place the analyzer in hold before removing the sensor for calibration and maintenance. Be sure to remove the analyzer from hold once calibration is complete. During hold, both outputs remain at the last value. Once in hold, all current outputs remain on Hold indefinitely. 5.6.2 Procedure. 1. If a security code has been programmed, selecting the Calibrate, Hold, Program or Display top menu items causes the security access screen to appear 5.7.2 Using the Hold Function To hold the outputs, 1.

The auto­recognition feature of the analyzer will enable the appropriate calibration screens to allow calibration for any single sensor configuration or dual sensor config­ uration of the analyzer. Completion of Quick Start upon first power up enables live measurements but does not ensure accurate readings in the lab or in process. Calibration should be performed with each attached sensor to ensure accurate, repeatable readings. This section covers the following programming and configuration functions: 4.

Regular recalibration is also necessary. Use auto calibration instead of manual calibration. Auto calibration avoids common pitfalls and reduces errors. The analyzer recognizes the buffers and uses temperature­corrected pH values in the calibration. Once the Model 1056 successfully completes the calibration, it calcu­ lates and displays the calibration slope and offset. The slope is reported as the slope at 25°C.

The process of making the two readings agree is called standardization. During standardization, the difference between the two pH values is converted to the equivalent voltage. The voltage, called the reference offset, is added to all subsequent measured cell voltages before they are converted to pH. If a standardized sensor is placed in a buffer solution, the measured pH will differ from the buffer pH by an amount equivalent to the standardization offset. tion.

The cell constant printed on the label is sufficiently accurate for most applications. CALIBRATING AN IN­SERVICE CONDUCTIVITY SENSOR 1. After a conductivity sensor has been in service for a period of time, recalibration may be necessary. There are three ways to calibrate a sensor. a. Use a standard instrument and sensor to measure the conductivity of the process stream. It is not necessary to remove the sensor from the process piping. The temperature correction used by the standard instrument may not exactly match the temperature correction used by the Model 1056. To avoid errors, turn off temperature correction in both the analyzer and the standard instrument. b. Place the sensor in a solution of known conductivity and make the analyzer reading match the conductivity of the standard solution. Use this method if the sensor can be easily removed from the process piping and a standard is available. Be careful using standard solutions having conductivity less than 100 µS/cm. Low conductivity standards are highly susceptible to atmospheric contamination. Avoid calibrating sensors with 0.01/cm cell constants against conductivity standards having conductivity greater than 100 µS/cm. The resistance of these solutions may be too low for an accurate measurement. Calibrate sensors with 0.01/cm cell constant using method c. c. To calibrate a 0.01/cm sensor, check it against a standard instrument and 0.01/cm sensor while both sensors are measuring water having a conductivity between 5 and 10 µS/cm. To avoid drift caused by absorption of atmospheric carbon dioxide, saturate the sample with air before making the measurements. To ensure adequate flow past the sensor during calibration, take the sample downstream from the sensor. For best results, use a flow­through standard cell. If the process temperature is much different from ambient, keep connecting lines short and insulate the flow cell.

The following calibration routines are covered in the family of supported Chlorine sensors: • Air Cal • Zero Cal • In Process Cal 7.6.1 CALIBRATION — FREE CHLORINE 7.6.1.1 DESCRIPTION A free chlorine sensor generates a current directly proportional to the concentration of free chlorine in the sam­ ple. Calibrating the sensor requires exposing it to a solution containing no chlorine (zero standard) and to a solu­ tion containing a known amount of chlorine (full­scale standard). The zero calibration is necessary because chlo­ rine sensors, even when no chlorine is in the sample, generate a small current called the residual current. The analyzer compensates for the residual current by subtracting it from the measured current before converting the result to a chlorine value. New sensors require zeroing before being placed in service, and sensors should be zeroed whenever the electrolyte solution is replaced. Either of the following makes a good zero standard: • Deionized water containing about 500 ppm sodium chloride. Dissolve 0.5 grams (1/8 teaspoonful) of table salt in 1 liter of water. DO NOT USE DEIONIZED WATER ALONE FOR ZEROING THE SENSOR. THE CONDUCTIVITY OF THE ZERO WATER MUST BE GREATER THAN 50 μS/cm. • Tap water known to contain no chlorine. Expose tap water to bright sunlight for at least 24 hours. The purpose of the In Process calibration is to establish the slope of the calibration curve. Because stable chlorine standards do not exist, the sensor must be calibrated against a test run on a grab sample of the process liquid. Several manufacturers offer portable test kits for this purpose. Observe the following precautions when taking and testing the grab sample. • Take the grab sample from a point as close to the sensor as possible. Be sure that taking the sample does not alter the flow of the sample to the sensor. It is best to install the sample tap just downstream from the sensor. • Chlorine solutions are unstable. Run the test immediately after taking the sample. Try to calibrate the sensor when the chlorine concentration is at the upper end of the normal operating range.

The continuous determination of total chlorine requires two steps. First, the sample flows into a conditioning system (TCL) where a pump continuously adds acetic acid and potassium iodide to the sample. The acid lowers the pH, which allows total chlorine in the sample to quantitatively oxidize the iodide in the reagent to iodine. In the second step, the treated sample flows to the sensor. The sensor is a membrane­covered amperometric sensor, whose output is proportional to the concentration of iodine. Because the concentration of iodine is proportional to the concentration of total chlorine, the analyzer can be calibrated to read total chlorine. Because the sensor really measures iodine, calibrating the sensor requires exposing it to a solution containing no iodine (zero standard) and to a solution containing a known amount of iodine (full­scale standard). The Zero calibration is necessary because the sensor, even when no iodine is present, generates a small current called the residual current. The analyzer compensates for the residual current by subtracting it from the measured current before converting the result to a total chlorine value. New sensors require zeroing before being placed in service, and sensors should be TABLE 7­ 6 Measure Total Chlorine zeroed whenever the electrolyte solution is replaced. The best zero standard is deionized water. The purpose of the In Process Calibration is to establish the slope of the calibration curve. Because stable total chlorine standards do not exist, the sensor must be calibrated against a test run on a grab sample of the process liquid. Several manufac­ turers offer portable test kits for this purpose. Observe the following precautions when taking and testing the grab sample: • Take the grab sample from a point as close as possible to the inlet of the TCL sample conditioning system. Be sure that taking the sample does not alter the flow through the TCL. • Chlorine solutions are unstable. Run the test immedi­ ately after taking the sample. Try to calibrate the sensor when the chlorine concentration is at the upper end of the normal operating range. Note this measurement must be made using the Model TCL total chlorine sample conditioning system. THIS SECTION DESCRIBES HOW TO CALIBRATE THE MODEL 1056 WITH AN ATTACHED TOTAL CHLORINE SENSOR.

Calibrating the sensor requires exposing it to a solution containing no oxygen (zero standard) and to a solution containing a known amount of oxygen (full­scale standard). The Zero Calibration is necessary because oxygen sensors, even when no oxygen is present in the sample, generate a small current called the residual current. The analyzer compensates for the residual current by subtracting it from the measured current before converting the result to a dissolved oxygen value. New sensors require zeroing before being placed in service, and sensors should be zeroed whenever the electrolyte solution is replaced. The recommended zero standard is 5% sodium sulfite in water, although oxygen­free nitrogen can also be used. The Model 499A TrDO sensor, used for the determination of trace (ppb) oxygen levels, has very low residual current and does not normally require zeroing. The residual current in the 499A TrDO sensor is equivalent to less than 0.5 ppb oxygen. The purpose of the In Process Calibration is to establish the slope of the calibration curve. Because the solubility of atmospheric oxygen in water as a function of temperature and barometric pressure is well known, the natural choice for a full­scale standard is air­saturated water. However, air­saturated water is difficult to prepare and use, so the universal practice is to use air for calibration. From the point of view of the oxygen sensor, air and air­saturated water are identical. The equivalence comes about because the sensor really measures the chemical potential of oxygen. Chemical potential is the force that causes oxygen molecules to diffuse from the sample into the sensor where they can be measured. It is also the force that causes oxygen molecules in air to dissolve in water and to continue to dissolve until the water is saturated with oxygen. Once the water is saturated, the chemical potential of oxygen in the two phases (air and water) is the same. Oxygen sensors generate a current directly proportional to the rate at which oxygen molecules diffuse through a membrane stretched over the end of the sensor. The 92 SECTION 7.0 CALIBRATION diffusion rate depends on the difference in chemical potential between oxygen in the sensor and oxygen in the sample. An electrochemical reaction, which destroys any oxygen molecules entering the sensor, keeps the concentration (and the chemical potential) of oxygen inside the sensor equal to zero. Therefore, the chemical potential of oxygen in the sample alone deter­ mines the diffusion rate and the sensor current. When the sensor is calibrated, the chemical potential of oxygen in the standard determines the sensor current. Whether the sensor is calibrated in air or air­saturated water is immaterial. The chemical potential of oxygen is the same in either phase. Normally, to make the calculation of solubility in common units (like ppm DO) simpler, it is convenient to use water­saturated air for calibration. Automatic air calibration is standard. The user simply exposes the sensor to water­saturated air. The analyzer monitors the sensor current. When the current is stable, the analyzer stores the current and measures the temperature using a temperature element inside the oxygen sensor. The user must enter the barometric pressure. From the temperature the analyzer calculates the saturation vapor pressure of water. Next, it calculates the pressure of dry air by subtracting the vapor pressure from the barometric pressure. Using the fact that dry air always contains 20.95% oxygen, the analyzer calcu­ lates the partial pressure of oxygen. Once the analyzer knows the partial pressure of oxygen, it uses the Bunsen coefficient to calculate the equilibrium solubility of atmospheric oxygen in water at the prevailing tem­ perature. At 25°C and 760 mm Hg, the equilibrium sol­ ubility is 8.24 ppm. Often it is too difficult or messy to remove the sensor from the process liquid for calibra­ tion. In this case, the sensor can be calibrated against a measurement made with a portable laboratory instru­ ment. The laboratory instrument typically uses a mem­ brane­covered amperometric sensor that has been cali­ brated against water­saturated air.

Calibrating the sensor requires exposing it to a solution containing no ozone (zero standard) and to a solution containing a known amount of ozone (full­scale standard). The Zero Calibration is necessary because ozone sensors, even when no ozone is in the sample, generate a small current called the residual or zero current. The analyzer compensates for the residual current by subtracting it from the measured current before converting the result to an ozone value. New sensors require zeroing before being placed in service, and sensors should be zeroed whenever the electrolyte solution is replaced. The best zero standard is deionized water. against a test run on a grab sample of the process liquid. Several manufacturers offer portable test kits for this purpose. Observe the following precautions when taking and testing the grab sample. • Take the grab sample from a point as close to the sensor as possible. Be sure that taking the sample does not alter the flow of the sample to the sensor. It is best to install the sample tap just downstream from the sensor. • Ozone solutions are unstable. Run the test immedi­ ately after taking the sample. Try to calibrate the sensor when the ozone concentration is at the upper end of the normal operating range.

The calibration requires two steps. First, immerse the sensor in filtered water having very low turbidity and measure the sensor output. Next, increase the turbidity of the filtered water by a known amount, typically 20 NTU, and measure the sensor output again. The analyzer takes the two measure­ ments, applies a linearization correction (if necessary), and calculates the sensitivity. Sensitivity is the sensor output (in mV) divided by turbidity. A typical new sen­ sor has a sensitivity of about 10 mV/NTU. As the sen­ sor ages, the sensitivity decreases. The figure below illustrates how turbidity calibration works. Before beginning the calibration, the analyzer does a dark current measurement. Dark current is the signal gener­ ated by the detector when no light is falling on it. The analyzer subtracts the dark current from the raw scat­ 98 The following screen will appear. S1: 1.234µS/cm 25.0ºC S2: 12.34pH 25.0ºC SN Calibrate?
