SECTION 1.0

DESCRIPTION AND SPECIFICATIONS

Model Xmt Family of Two-wire Transmitters

• CHOICE OF COMMUNICATION PROTOCOLS:

HART

or FOUNDATION®Fieldbus

• CLEAR, EASY-TO-READ two-line display shows commissioning menus

and process measurement displays in English

• SIMPLE TO USE MENU STRUCTURE

• CHOICE OF PANEL OR PIPE/SURFACE MOUNTING

• NON-VOLATILE MEMORY retains program settings and calibration

data during power failures

• SIX LOCAL LANGUAGES - English, French, German, Italian, Spanish and Portuguese

1.1 FEATURES AND APPLICATIONS

The Solu Comp Model Xmt family of transmitters can be used to measure pH, ORP, conductivity (using either contacting or toroidal sensors), resistivity, oxygen (ppm and ppb level), free chlorine, total chlorine, monochloramine and ozone in a variety of process liquids. The Xmt is compatible with most Rosemount Analytical sensors. See the Specification sections for details.

The transmitter has a rugged, weatherproof, corrosionresistant enclosure (NEMA 4X and IP65). The panel mount version fits standard ½ DIN panel cutouts, and its shallow depth is ideally suited for easy mounting in cabinet-type enclosures. A panel mount gasket is included to maintain the weather rating of the panel. Surface/pipe mount enclosure includes self-tapping screws for surface mounting. A pipe mounting accessory kit is available for mounting to a 2-inch pipe.

The transmitter has a two-line 16-character display. Menu screens for calibrating and registering choices are simple and intuitive. Plain language prompts guide the user through the procedures. There are no service codes to enter before gaining access to menus.

Two digital communication protocols are available: HART (model option -HT) and F

OUNDATION fieldbus (model option

-FF or -FI). Digital communications allow access to AMS

(Asset Management Solutions). Use AMS to set up and configure the transmitter, read process variables, and troubleshoot problems from a personal computer or host anywhere in the plant.

The seven-button membrane-type keypad allows local programming and calibrating of the transmitter. The HART Model 375 communicator can also be used for programming and calibrating the transmitter.

The Model Xmt-P Transmitter with the appropriate sensor

measures dissolved oxygen (ppm and ppb level), free chlorine, total chlorine, monochloramine, and ozone in water and aqueous solutions. The transmitter is compatible with Rosemount Analytical 499A amperometric sensors for oxygen, chlorine, monochloramine, and ozone; and with Hx438, Bx438, and Gx448 steam-sterilizable oxygen sensors.

For free chlorine measurements, both automatic and manual pH correction are available. pH correction is necessary because amperometric free chlorine sensors respond only to hypochlorous acid, not free chlorine, which is the sum of hypochlorous acid and hypochlorite ion. To measure free chlorine, most competing instruments require an acidified sample. Acid lowers the pH and converts hypochlorite ion to hypochlorous acid. The Model Xmt-P eliminates the need for messy and expensive sample conditioning by measuring the sample pH and using it to correct the chlorine sensor signal. If the pH is relatively constant, a fixed pH correction can be used, and the pH measurement is not necessary. If the pH is greater than 7.0 and fluctuates more than about 0.2 units, continuous measurement of pH and automatic pH correction is necessary. See Specifications section for recommended pH sensors. Corrections are valid to pH 9.5.

The transmitter fully compensates oxygen, ozone, free chlorine, total chlorine, and monochloramine readings for changes in membrane permeability caused by temperature changes.

For pH measurements — pH is available with free chlorine only — the Xmt-P features automatic buffer recognition and stabilization check. Buffer pH and temperature data for commonly used buffers are stored in the transmitter. Glass impedance diagnostics warn the user of an aging or failed pH sensor.

SENSOR COMPATIBILITY CHART

1.2.2 FUNCTIONAL SPECIFICATIONS

pH Range: 0 to 14 ORP

Range: -1400 to +1400mV

Calibrations/standardization: The automatic buffer

recognition uses stored buffer values and their temperature curves for the most common buffer standards available worldwide. The transmitter also performs a stabilization check on the sensor in each buffer.

A manual two-point calibration is made by immersing the sensor in two different buffer solutions and entering the pH values. The microprocessor automatically calculates the slope which is used for self-diagnostics. An error message will be displayed if the pH sensor is faulty. This slope can be read on the display and/or manually adjusted if desired.

An on-line one-point process standardization is accomplished by entering the pH or ORP value of a grab sample.

Preamplifier Location: A preamplifier must be used to

convert the high impedance pH electrode signal to a low impedance signal for transmitter use. The integral preamplifier of the Model Xmt-P may be used when the sensor to transmitter distance is less than 15 ft (4.5 m). Locate the preamplifier in the sensor or junction box for longer distances.

Automatic Temperature Compensation: External 3-wire

Pt100 RTD or Pt1000 RTD located in the sensor, compensates the pH reading for temperature fluctuations. Compensation covers the range -15 to 130°C (5 to 270°F). Manual temperature compensation is also selectable.

Accuracy: ±1.4 mV @ 25°C ± 0.01 pH Repeatability: ±1 mV @ 25°C ±0.01 pH

Diagnostics: The internal diagnostics can detect:

Calibration Error Sensor Failure

High Temperature Warning CPU Failure Low Temperature Warning Input Warning ROM Failure Glass Warning Glass Failure Reference Warning Reference Failure

Once one of the above is diagnosed, the display will show a message describing the problem.

1.6 HART COMMUNICATIONS

1.6.1 OVERVIEW OF HART COMMUNICATION

HART (highway addressable remote transducer) is a digital communication system in which two frequencies are superimposed on the 4 to 20 mA output signal from the transmitter. A 1200 Hz sine wave represents the digit 1, and a 2400 Hz sine wave represents the digit 0. Because the average value of a sine wave is zero, the digital signal adds no dc component to the analog signal. HART permits digital communication while retaining the analog signal for process control.

The HART protocol, originally developed by Fisher-Rosemount, is now overseen by the independent HART Communication Foundation. The Foundation ensures that all HART devices can communicate with one another. For more information about HART communications, call the HART Communication Foundation at (512) 794-0369. The internet address is http://www.hartcomm.org.

1.6.2 HART INTERFACE DEVICES

The Model 375 HART Communicator is a hand-held device that provides a common link to all HART SMART instruments and allows access to AMS (Asset Management Solutions). Use the HART communicator to set up and control the Xmt-P-HT and to read measured variables. Press ON to display the on-line menu. All setup menus are available through this menu.

HART communicators allow the user to view measurement data (pH, ORP and temperature), program the transmitter, and download information from the transmitter for transfer to a computer for analysis. Downloaded information can also be sent to another HART transmitter. Either a hand-held communicator, such as the Rosemount Model 375, or a computer can be used. HART interface devices operate from any wiring termination point in the 4 - 20 mA loop. A minimum load of 250 ohms must be present between the transmitter and the power supply. See Figure 1-4.

If your communicator does not recognize the Model XMT pH/ORP transmitter, the device description library may need updating. Call the manufacturer of your HART communication device for updates.

DESCRIPTION AND SPECIFICATIONS

FIGURE 1-4. HART Communicators.

Both the Rosemount Model 375 (or 275) and a computer can be used to communicate with a HART transmitter. The 250 ohm load (minimum) must be present between the transmitter and the power supply.

1.8 ASSET MANAGEMENT SOLUTIONS

Asset Management Solutions (AMS) is software that helps plant personnel better monitor the performance of analytical instruments, pressure and temperature transmitters, and control valves. Continuous monitoring means maintenance personnel can anticipate equipment failures and plan preventative measures before costly breakdown maintenance is required.

AMS uses remote monitoring. The operator, sitting at a computer, can view measurement data, change program settings, read diagnostic and warning messages, and retrieve historical data from any HART-compatible device, including the Model XMT-P transmitter. Although AMS allows access to the basic functions of any HART compatible device, Rosemount Analytical has developed additional software for that allows access to all features of the Model XMT-P transmitter.

AMS can play a central role in plant quality assurance and quality control. Using AMS Audit Trail, plant operators can track calibration frequency and results as well as warnings and diagnostic messages. The information is available to Audit Trail whether calibrations were done using the infrared remote controller, the Model 375 HART communicator, or AMS software.

AMS operates in Windows 95. See Figure 1-5 for a sample screen. AMS communicates through a HART-compatible modem with any HART transmitters, including those from other manufacturers. AMS is also compatible with F

OUNDATION™

Fieldbus, which allows future upgrades to Fieldbus instruments.

Rosemount Analytical AMS windows provide access to all transmitter measurement and configuration variables. The user can read raw data, final data, and program settings and can reconfigure the transmitter from anywhere in the plant.

2.1 UNPACKING AND INSPECTION

Inspect the shipping container. If it is damaged, contact the shipper immediately for instructions. Save the box. If there is no apparent damage, remove the transmitter. Be sure all items shown on the packing list are present. If items are missing, immediately notify Rosemount Analytical.

Save the shipping container and packaging. They can be reused if it is later necessary to return the transmitter to the factory.

2.2 PRE-INSTALLATION SETUP

2.2.1 Temperature Element

The Model XMT-P pH/ORP transmitter is compatible with sensors having Pt 100 and Pt 1000. Sensors from other manufacturers may have a Pt 1000 RTD. For Rosemount Analytical sensors, the type of temperature element in the sensor is printed on the tag attached to the sensor cable. For the majority of sensors manufactured by Rosemount Analytical, the RTD IN lead is red and the RTD RTN lead is white. The Model 328A sensor has no RTD. The Model 320HP system has a readily identifiable separate temperature element. Resistance at room temperature for common RTDs is given in the table.

If the resistance is... the temperature element is a about 110 ohms Pt 100 RTD about 1100 ohms Pt 1000 RTD

2.2.2 Reference Electrode Impedance

The standard silver-silver chloride reference electrode used in most industrial and laboratory pH electrodes is low impedance. EVERY pH and ORP sensor manufactured by Rosemount Analytical has a low impedance reference. Certain specialized applications require a high impedance reference electrode. The transmitter must be re-programmed to recognize the high impedance reference.

MODEL XMT-P pH/ORP SECTION 2.0

INSTALLATION

2.2.3 Preamplifier Location

pH sensors produce a high impedance voltage signal that must be preamplified before use. The signal can be preamplified before it reaches the transmitter or it can be preamplified in the transmitter. To work properly, the transmitter must know where preamplification occurs. Although ORP sensors produce a low impedance signal, the voltage from an ORP sensor is amplified the same way as a pH signal.

If the sensor is wired to the transmitter through a junction box, the preamplifier is ALWAYS in either the junction box or the sensor. Junction boxes can be attached to the sensor or installed some distance away. If the junction box is not attached to the sensor, it is called a remote junction box. In most junction boxes used with the Model XMT-P pH/ORP, a flat, black plastic box attached to the same circuit board as the terminal strips houses the preamplifier. The preamplifier housing in the 381+ sensor is crescent shaped.

If the sensor is wired directly to the transmitter, the preamplifier can be in the sensor or in the transmitter. If the sensor cable has a GREEN wire, the preamplifier is in the sensor. If there is no green wire, the sensor cable will contain a coaxial cable. A coaxial cable is an insulated wire surrounded by a braided metal shield. Depending on the sensor model, the coaxial cable terminates in either a BNC connector or in a separate ORANGE wire and CLEAR shield.

MODEL XMT-P pH/ORP SECTION 2.0

INSTALLATION

2.3 INSTALLATION

1. Although the transmitter is suitable for outdoor use,

do not install it in direct sunlight or in areas of extreme temperatures.

2. Install the transmitter in an area where vibrations and

electromagnetic and radio frequency interference are minimized or absent.

3. Keep the transmitter and sensor wiring at least one

foot from high voltage conductors. Be sure there is easy access to the transmitter.

4. The transmitter is suitable for panel (Figure 2-3), pipe

(Figure 2-4), or surface (Figure 2-5) mounting.

5. The transmitter case has two 1/2-inch (PG13.5) con-

duit openings and either three or four 1/2-inch knockouts. The panel mount Xmt-P-HT has four knockouts. The pipe/surface mount transmitter has three knockouts*. One conduit opening is for the power/output cable; the other opening is for the sensor cable.

Figure 1 shows how to remove a knockout. The knockout grooves are on the outside of the case. Place the screwdriver blade on the inside of the case and align it approximately along the groove. Rap the screwdriver sharply with a hammer until the groove cracks. Move the screwdriver to an uncracked portion of the groove and continue the process until the knockout falls out. Use a small knife to remove the flash from the inside of the hole.

6. Use weathertight cable glands to keep moisture out to

the transmitter. If conduit is used, plug and seal the connections at the transmitter housing to prevent moisture from getting inside the instrument.

7. To reduce the likelihood of stress on wiring connec-

tions, do not remove the hinged front panel (-11 models) from the base during wiring installation. Allow sufficient wire leads to avoid stress on conductors.

*NEMA plug may be supplied instead of knockout for pipe/surface version.

3.1 POWER SUPPLY/CURRENT LOOP —

MODEL XMT-P-HT

3.1.1 Power Supply and Load Requirements.

Refer to Figure 3-1.

The supply voltage must be at least 12.0 Vdc at the transmitter terminals. The power supply must be able to cover the voltage drop on the cable as well as the load resistor (250 Ω minimum) required for HART communications. The maximum power supply voltage is

42.0 Vdc. For intrinsically safe installations, the maximum power

supply voltage is 30.0 Vdc. The graph shows load and power supply requirements. The upper line is the power supply voltage needed to provide 12 Vdc at the transmitter terminals for a 22 mA current. The lower line is the power supply voltage needed to provide 30 Vdc for a 22 mA current.

The power supply must provide a surge current during the first 80 milliseconds of startup. The maximum current is about 24 mA.

For digital communications, the load must be at least 250 ohms. To supply the 12.0 Vdc lift off voltage at the transmitter, the power supply voltage must be at least 17.5 Vdc.

FIGURE 3-1. Load/Power Supply Requirements

FIGURE3-2. Power Supply/Current Loop Wiring

3.1.2 Power Supply-Current Loop

Wiring.

Refer to Figure 3-2.

Run the power/signal wiring through the opening nearest TB-2.

For optimum EMI/RFI protection . . .

1. Use shielded power/signal cable

and ground the shield at the power supply.

2. Use a metal cable gland and be

sure the shield makes good electrical contact with the gland.

3. Use the metal backing plate (see

Figure 2-6) when attaching the gland to transmitter enclosure.

The power/signal cable can also be enclosed in an earth-grounded metal conduit.

Do not run power supply/signal wiring in the same conduit or cable tray with AC power lines or with relay actuated signal cables. Keep power supply/signal wiring at least 6 ft (2 m) away from heavy electrical equipment.

3.3.1 Sensor Wiring Information

pH and ORP sensors manufactured by Rosemount Analytical can be wired to the Model XMT-P transmitter in three ways:

1. directly to the transmitter,

2. to a sensor-mounted junction box and then to the transmitter,

3. to a remote junction box and then from the remote junction box to the transmitter.

The pH (or ORP) signal can also be preamplified in one of four places. See Section 7.4.3 for set-up. The transmitter is factory configured with a preamplifier.

1. in the sensor (a, d),

2. in a junction box mounted on the sensor (c),

3. in a remote junction box (e).

4. at the transmitter (b).

NOTE: For 22K NTC RTDs, wire leads to TB1-1 and TB1-3.

3.3.2 General Wiring Configurations

Figure 3-5 illustrates the various wiring arrangements for Xmt-P.

DISPLAY AND OPERATION

SECTION 5.0

DISPLAY AND OPERATION

5.1. DISPLAY

The Model Xmt-P has a two-line display. Generally, the user can program the transmitter to show one of three displays. If the transmitter has been configured to measure ORP or Redox, similar displays are available. Figure 5-1 shows the displays available for pH.

The transmitter has information screens that supplement the data in the main display. Press q to view the information screens. The first information screen shows the type of measurement being made (pH, ORP, Redox). The last information

screen is the software version number.

During calibration and programming, key presses cause different displays to appear. The displays are self-explanatory and guide the user step-by-step through the procedure.

5.2 KEYPAD

Figure 5-2 shows the Solu Comp Xmt keypad.

FIGURE 5-1. Displays During Normal Operation

Screen A shows the pH reading, the temperature, and the output current generated by the transmitter. Screen B shows the same information as Screen A except the output current has been substituted with the raw sensor voltage. Screen C is most useful while troubleshooting sensor problems.

FIGURE 5-2. Solu Comp Xmt Keypad

Four arrow keys move the cursor around the screen. A blinking word or numeral show the position of the cursor. The arrow keys are also used to change the value of a numeral. Pressing ENTER stores numbers and settings and moves the display to the next screen. Pressing EXIT returns to the previous screen without storing changes. Pressing MENU always causes the main menu screen to appear. Pressing MENU followed by EXIT causes the main display to appear.

5.3 PROGRAMMING AND CALIBRATING THE MODEL XMT

- TUTORIAL

Setting up and calibrating the Model Xmt is easy. The following tutorial describes how to move around in the programming menus. For practice, the tutorial also describes how to assign values to the 4 and 20 mA output.

1. If the menu screen (shown at the left) is not already showing, press MENU. Calibrate is blinking, which means the cursor is on Calibrate.

2. To assign values to the current output, the Program sub-menu must be open. Press q. The cursor moves to Program (Program blinking.) Press ENTER. Pressing ENTER opens the Program sub-menu.

3. The Program sub-menu permits the user to configure and assign val- ues to the 4-20 mA output, to test and trim the output, to change the type of measurement from what was selected during Quick Start, to set manual or automatic temperature correction for membrane permeability, and to set security codes. When the sub-menu opens, Output is blinking, which means the cursor is on Output. Press q or

u (or any arrow

key) to move the cursor around the display. Move the cursor to >> and press ENTER to cause a second screen with more program items to appear. There are three screens in the Program sub-menu. Pressing >> and ENTER in the third screen cause the display to return to the first screen (Output, Temp, Measurement).

4. For practice, assign values to the 4 and 20 mA output. Move the cursor to Output and press ENTER.

5. The screen shown at left appears. Test is blinking. Move the cursor to Range and press ENTER.

6. The screen shown at left appears. + is blinking, which means the cursor is on +.

a. To toggle between + and - press p or q.

b. To move from one digit to the next, press t or u.

c. To increase or decrease the value of a digit, press p or q.

d. To move the decimal point, press t or u until the cursor is on the

decimal point. Press p to move the decimal to the right. Press q to move the decimal point to the left.

e. Press ENTER to store the number.

7. The screen shown at left appears. Use this screen to assign a full scale value to the 20 mA output. Use the arrow keys to change the number to the desired value. Press ENTER to store the setting.

8. The screen shown at left appears. To configure the output or to test the output, move the cursor to the appropriate place and press ENTER.

9. To return to the main menu, press MENU. To return to the main display, press MENU then EXIT, or press EXIT repeatedly until the main display appears. To return to the previous display, press EXIT.

NOTE

To store values or settings, press ENTER before pressing EXIT.

DISPLAY AND OPERATION

5.4 MENU TREES - pH

The Model Xmt-P pH transmitter has four menus: CALIBRATE, PROGRAM, HOLD, and DISPLAY. Under the Calibrate and Program menus are several sub-menus. For example, under CALIBRATE, the sub-menus are Temperature and pH or ORP/Redox. Under each sub-menu are prompts. Under PROGRAM, the sub-menus for Xmt-P-HT are Output, Temp, Measurement, Security, HART, Diagnostics, Noise Rejection, and Reset Analyzer. The HOLD menu (HART only) enables or disables the 4-20 mA outputs. The DISPLAY menu allows the user to configure the main display information fields and to adjust the LCD display contrast. Figure 5-5 shows the complete menu tree for Model Xmt-P-HT. Figure 5-6 shows the complete menu tree for Model Xmt-P-FF.

5.5 DIAGNOSTIC MESSAGES - pH

Whenever a warning or fault limit has been exceeded, the transmitter displays diagnostic messages to aid in troubleshooting. “Fault” or “Warn” appears in the main display to alert the user of an adverse condition. The display alternates between the regular display and the Fault or Warning message. If more than one warning or fault message has been generated, the messages appear alternately.

See Section 10.0, Troubleshooting, for the meanings of the fault and warning messages.

5.6 SECURITY

5.6.1 How the Security Code Works

Use security codes to prevent accidental or unwanted changes to program settings, displays, and calibration. Two three-digit security codes can be used to do the following…

a. Allow a user to view the default display and information screens only. b. Allow a user access to the calibration and hold menus only. c. Allow a user access to all the menus.

5.6.2 Bypassing the Security Code

Enter 555. The main menu will open.

5.6.3 Setting a Security Code

See Section 7.6.

5.7 USING HOLD

5.7.1 Purpose

The transmitter output is always proportional to the process variable (oxygen, free chlorine, total chlorine, monochloramine, or ozone). To prevent improper operation of control systems or dosing pumps, place the transmitter in hold before removing the sensor for maintenance. Be sure to remove the transmitter from hold once the work is complete and the sensor has been returned to the process liquid. During hold the transmitter current goes to the value programmed by the user. Once in hold, the transmitter remains there indefinitely. While in hold, the word "hold" appears periodically in the display.

5.7.2 Using the Hold Function

1. Press MENU. The main menu screen appears. Choose Hold.

2. The Hold Output screen appears. Choose Yes to put the transmitter in hold.

3. The top line in the display is the present current output. Use the arrow keys to change the number in the second line to the desired current during hold.

4. The main display screen appears.

5. To take the transmitter out of hole, repeat steps 1 and 2 and choose No in step 2.

Output Range? 10.00mA

Hold at 20.00mA

6.3 Operation

6.3.1 Off-line and On-line Operation

The Model 375 Communicator features off-line and on-line communications. On-line means the communicator is connected to the transmitter in the usual fashion. While the communicator is on line, the operator can view measurement data, change program settings, and read diagnostic messages. Off-line means the communicator is not connected to the transmitter. When the communicator is off line, the operator can still program settings into the communicator. Later, after the communicator has been connected to a transmitter, the operator can transfer the programmed settings to the transmitter. Off-line operation permits settings common to several transmitters to be easily stored in all of them.

PROGRAMMING THE TRANSMITTER

SECTION 7.0

PROGRAMMING THE TRANSMITTER

7.1 GENERAL

This section describes how to program the transmitter using the keypad.

1. Configure and assign values to the 4-20 mA output (-HT version only).

2. Test and trim the current output (-HT version only).

3. Select the measurement to be made (pH, ORP, or Redox).

4. Choose temperature units and automatic or manual temperature mode.

5. Set a security code.

6. Make certain settings relating to HART communication (-HT version only).

7. Program the transmitter for maximum reduction of environmental noise.

8. Resetting factory default settings.

9. Selecting a default display screen and adjusting screen contrast.

7.2 CHANGING START-UP SETTINGS

When the Solu Comp Xmt is powered up for the first time, startup screens appear. The screens prompt the user to enter the measurement being made, to identify the sensor being used, to select automatic or manual pH correction and to select temperature units. If incorrect settings were entered at startup, enter the correct settings now. To change the measurement, refer to Section 7.4.

7.3 CONFIGURING AND RANGING THE OUTPUT (-HT version only)

7.3.1 Purpose

1. Configuring an output means

a. displaying the output reading in units of mA or percent of full scale.

b. changing the time constant for output dampening.

c. assigning the value the output current will take if the transmitter detects a fault in itself or the sensor.

2. Ranging the output means assigning values to the 4 mA and 20 mA outputs.

3. Testing an output means entering a test value from the keypad to check the operation of recorders or controllers.

4. Trimming an output means calibrating the 4 and 20 mA current outputs against a referee milliammeter.

7.3.2 Definitions

1. CURRENT OUTPUT. The transmitter provides a continuous 4-20 mA output current directly proportional to the pH of the sample.

2. FAULT. The transmitter continuously monitors itself and the sensor for faults. If the transmitter detects a fault, the 4-20 mA output can be programmed to go to a fixed value or it can be programmed to continue to display the live current reading. In any event Fault appears intermittently in the second line of the display.

3. DAMPEN. Output dampening smoothes out noisy readings. But it also increases the response time of the output. To estimate the time (in minutes) required for the output to reach 95% of the final reading following a step change, divide the setting by 20. Thus, a setting of 140 means that, following a step change, the output takes about seven minutes to reach 95% of final reading. The output dampen setting does not affect the response time of the process display. The maximum setting is 255.

4. TEST. The transmitter can be programmed to generate a test current.

7.4 CHOOSING AND CONFIGURING THE ANALYTICAL MEASUREMENT

7.4.1 Purpose

This section describes how to do the following:

1. Configure the transmitter to measure pH, ORP, or Redox.

2. Determine the location of the preamp.

3. If pH was selected, there are additional selections and settings to make:

a. choose a solution temperature correction curve or set a temperature coefficient constant

b. choose sensor isopotential

c. set reference impedance low or high

6. If total chlorine was selected, single or dual slope calibration must also be specified.

7.4.2 Definitions

1. MEASUREMENT. The transmitter can be configured to measure pH, ORP or Redox (opposite sign of ORP).

2. pH SETTINGS. If pH is selected, there are additional settings to make.

a. PREAMPLIFIER. The raw pH signal is a high impedance voltage. A voltage follower or preamplifier, locat-

ed either in the sensor or transmitter, converts the high impedance signal into a low impedance one. Normally, high impedance signals should be sent no further than about 15 feet.

b. REFERENCE OFFSET. Ideally, a pH sensor in pH 7 buffer should have a voltage of 0 mV. The difference

between the measured voltage in pH 7 buffer and the ideal value is the reference offset. Typically, the reference offset is less than 60 mV.

c. DIAGNOSTICS. The Solu Comp Xmt continuously monitors the pH sensor for faults. If it detects a fault,

the transmitter displays a fault message.

d. GLASS IMPEDANCE. The transmitter monitors the condition of the pH-sensitive glass membrane in the

sensor by continuously measuring the impedance across the membrane. Typical impedance is between 100 and 500 MΩ. Low impedance (<10 MΩ) implies the glass bulb has cracked and the sensor must be replaced. An extremely high impedance (>1000 MΩ) implirs the sensor is aging and may soon need replacement. High impedance might also mean that the glass membrane is no longer immersed in the process liquid.

3. INPUT FILTER. The raw sensor current can be filtered to reduce noise. Filtering also increases the response time. The filter is the time required for the input to reach 63% of its final reading following a step change.

7.5.1 Purpose

This section describes how to do the following:

1. Choose temperature display units (°C or °F).

2. Choose automatic or manual temperature compensation.

3. Enter a temperature for manual temperature compensation

7.5.2 Definitions

1. AUTOMATIC TEMPERATURE COMPENSATION. The analyzer uses a temperature-dependent factor to con-

vert measured cell voltage to pH. In automatic temperature compensation, the analyzer measures the temperature and automatically calculates the correct conversion factor. For maximum accuracy, use automatic temperature compensation.

2. MANUAL TEMPERATURE COMPENSATION. In manual temperature compensation, the analyzer converts

measured voltage to pH using the temperature entered by the user. It does not use the actual process temperature. Do NOT use manual temperature compensation unless the process temperature varies no more than about ±2°C or the pH is between 6 and 8. Manual temperature compensation is useful if the sensor temperature element has failed and a replacement sensor is not available. If manual temperature correction is selected, the display will not show the measured temperature. It will show the manually entered value.

CALIBRATION — TEMPERATURE

SECTION 8.0

CALIBRATION — TEMPERATURE

8.1 INTRODUCTION

The Calibrate Menu allows the user to calibrate the pH, ORP (or redox), and temperature response of the sensor.

8.2 CALIBRATING TEMPERATURE

8.2.1 Purpose

Temperature affects the measurement of pH in three ways.

1. The analyzer uses a temperature dependent factor to convert measured cell voltage to pH. Normally, a slight inaccuracy in the temperature reading is unimportant unless the pH reading is significantly different from 7.00. Even then, the error is small. For example, at pH 12 and 25°C, a 1°C error produces a pH error less than ±0.02.

2. During auto calibration, the Solu Comp Xmt recognizes the buffer being used and calculates the actual pH of the buffer at the measured temperature. Because the pH of most buffers changes only slightly with temperature, reasonable errors in temperature do not produce large errors in the buffer pH. For example, a 1°C error causes at most an error of ±0.03 in the calculated buffer pH.

3. The Solu Comp Xmt can be programmed to calculate and display pH at a reference temperature (25°C). The maximum change in solution pH with temperature is about ±0.04 pH/°C, so a 1°C temperature error does introduce a small error. However, the major source of error in solution temperature compensation is using an incorrect temperature coefficient.

Temperature affects the measurement of ORP in a complicated fashion that is best determined empirically.

Without calibration the accuracy of the temperature measurement is about ±0.4°C. Calibrate the sensor/analyzer combination if

1. ±0.4°C accuracy is not acceptable

2. the temperature measurement is suspected of being in error. Calibrate temperature by making the analyzer reading match the temperature measured with a standard thermometer.

MODEL XMT-P pH/ORP SECTION 8.0

CALIBRATION — TEMPERATURE

8.2.2 Procedure

1. Remove the sensor from the process. Place it in an insulated container of water along with a calibrated thermometer. Submerge at least the bottom two inches of the sensor. Stir continuously.

2. Allow the sensor to reach thermal equilibrium. For some sensors, the time constant for a change in temperature is 5 min., so it may take as long as 30 min. for temperature equilibration.

3. If the sensor cannot be removed from the process, measure the temperature of a flowing sample taken from a point as close to the sensor as possible. Let the sample continuously overflow an insulated container holding a calibrated thermometer.

4. Change the Solu Comp Xmt display to match the calibrated thermometer using the procedure below.

a. Press MENU. The menu screen appears. Choose Calibrate.

b. Choose Temp.

c. If transmitter was programmed in Section 7.5 to use the actual process

temperature, go to step 7.

If the transmitter was programmed to use a temperature entered by the user, go to step 9.

d. To calibrate the temperature, change the number in the second line to

match the temperature measured with the standard thermometer. Press ENTER.

e. Press MENU then EXIT to return to the main display.

f. If the temperature value shown in the display is not correct, use the

arrow keys to change it to the desired value. The transmitter will use the temperature entered in this step in all measurements and calculations, no matter what the true temperature is.

g. Press MENU then EXIT to return to the main display.

SECTION 9.0

CALIBRATION — pH

9.1 INTRODUCTION

For pH sensors, two-point buffer calibration is standard. Both automatic calibration and manual calibration are available. Auto calibration avoids common pitfalls and reduces errors. Its use is recommended. In auto calibration the Solu Comp Xmt calculates the actual pH of the buffer from the nominal value entered by the user and does not accept calibration data until readings are stable. In manual calibration the user enters buffer values and judges when readings are stable. The pH reading can also be standardized, that is, forced to match the reading from a referee instrument. Finally, if the user knows the electrode slope (at 25°C), he can enter it directly.

The ORP calibration is a single-point calibration against an ORP standard. A new pH sensor must be calibrated before use. Regular recalibration is also necessary. A pH measurement cell (pH sensor and the solution to be measured) can be pictured as a battery with an extreme-

ly high internal resistance. The voltage of the battery depends on the pH of the solution. The pH meter, which is basically a voltmeter with a very high input impedance, measures the cell voltage and calculates pH using a conversion factor. The actual value of the voltage-to-pH conversion factor depends on the sensitivity of the pH sensing element (and the temperature). The sensing element is a thin, glass membrane at the end of the sensor. As the glass membrane ages, the sensitivity drops. Regular recalibration corrects for the loss of sensitivity. pH calibration standards, also called buffers, are readily available.

In automatic calibration the transmitter recognizes the buffer and uses temperature-corrected pH values in the calibration. The table below lists the standard buffers the controller recognizes. The controller also recognizes several technical buffers: Merck, Ingold, and DIN 19267. Temperature-pH data stored in the controller are valid between at least 0 and 60°C.

FIGURE 9-1. Calibration Slope and Offset

Note 1: NIST is National Institute of Standards,

DIN is Deutsche Institute für Normung, JSI is Japan Standards Institute, and BSI is British Standards Institute.

Note 2: pH 7 buffer is not a standard buffer. It is a popular commercial buffer in the United States.

During automatic calibration, the transmitter also measures noise and drift and does not accept calibration data until readings are stable. Calibration data will be accepted as soon as the pH reading is constant to within the factory-set limits of 0.02 pH units for 10 seconds. The stability settings can be changed. See Section 7.10.

In manual calibration, the user judges when pH readings are stable. He also has to look up the pH of the buffer at the temperature it is being used and enter the value in the transmitter.

Once the transmitter completes the calibration, it calculates the calibration slope and offset. The slope is reported as the slope at 25°C. Figure 9-1 defines the terms.

The transmitter can also be standardized. Standardization is the process of forcing the transmitter reading to match the reading from a second pH instrument. Standardization is sometimes called a one-point calibration.

9.4 PROCEDURE — STANDARDIZATION

1. The pH measured by the transmitter can be changed to match the reading from a second or referee instrument. The process of making the two readings agree is called standardization.

2. During standardization, the difference between the two 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 after standardization the sensor is placed in a buffer solution, the measured pH will differ from the buffer pH by an amount equivalent to the standardization offset.

3. Install the pH sensor in the process liquid.

4. Once readings are stable, measure the pH of the liquid using a referee instrument.

5. Because the pH of the process liquid may change if the temperature changes, measure the pH of the grab sample immediately after taking it.

6. For poorly buffered samples, it is best to determine the pH of a continuously flowing sample from a point as close as possible to the sensor.

7. Press MENU. The main menu appears. Choose Calibrate.

The screen at left appears if the entered pH was greater than 14.00 or if the mV offset calculated by the transmitter during standardization exceeds the reference offset limit programmed into the transmitter. The display then returns to step 10. Repeat the standardization. To change the reference offset from the default value (60 mV), see section 7.4.

9.5 PROCEDURE — ENTERING A KNOWN SLOPE VALUE.

1. If the electrode slope is known from other measurements, it can be entered directly into the transmitter. The slope must be entered as the slope at 25°C. To calculate the slope at 25°C from the slope at temperature t°C, use the equation:

slope at 25°C = (slope at t°C)

Changing the slope overrides the slope determined from the previous buffer calibration.

9.6 ORP CALIBRATION

9.6.1 Purpose

1. For process control, it is often important to make the measured ORP agree with the ORP of a standard solution.

2. During calibration, the measured ORP is made equal to the ORP of a standard solution at a single point.

9.6.2 Preparation of ORP standard solutions

ASTM D1498-93 gives procedures for the preparation of iron (II) - iron (III) and quinhydrone ORP standards. The iron (II) - iron (III) standard is recommended. It is fairly easy to make, is not particularly hazardous, and has a shelf life of about one year. In contrast, quinhydrone standards contain toxic quinhydrone and have only an eight-hour shelf life.

Iron (II) - iron (III) standard is available from Rosemount Analytical as PN R508-16OZ. The ORP of the standard solution measured against a silver-silver chloride reference electrode is 476±20mV at 25°C. The redox potential is

-476±20mV at 25°C.

TROUBLESHOOTING

SECTION 10.0

TROUBLESHOOTING

10.1 OVERVIEW

The Xmt-P transmitter continuously monitors itself and the sensor for problems. If the transmitter detects a problem, the word "fault" or "warn" appears in the main display alternating with the measurement.

A fault condition means the measurement is seriously in error and is not to be trusted. A fault condition might also mean that the transmitter has failed. Fault conditions must be corrected immediately. When a fault occurs the output goes to 22.00 mA or the to value programmed in Section 7.3. The output can also be programmed to reflect the live measurement.

A warning means that the instrument is usable, but steps should be taken as soon as possible to correct the con- dition causing the warning.

See Section 10.2 for an explanation of fault and warning messages and suggested corrective actions.

The Xmt-P also displays error and warning messages if a calibration is seriously in error. Refer to the section below for assistance. Each section also contains hints for correcting other measurement and calibration problems.

10.2.1 RTD Open, RTD Ω Overrange, Temperature High, Temperature Low

These messages usually mean that the RTD (or thermistor in the case of the Hx338 and Hx348 sensors) is open or shorted or there is an open or short in the connecting wiring.

1. Verify all wiring connections, including wiring in a junction box, if one is being used.

2. Disconnect the RTD IN, RTD SENSE, and RTD RETURN leads or the thermistor leads at the transmitter. Be sure to note the color of the wire and where it was attached. Measure the resistance between the RTD IN and RETURN leads. For a thermistor, measure the resistance between the two leads. The resistance should be close to the value in the table in Section 10.8. If the temperature element is open (infinite resistance) or shorted (very low resistance), replace the sensor. In the meantime, use manual temperature compensation.

MODEL Xmt-P SECTION 10.0

TROUBLESHOOTING

10.2.2 Broken pH Glass and pH Glass Z High

These messages mean that the pH sensor glass impedance is outside the programmed limits. To read the impedance go to the main display and press êuntil Glass Imp appears in the display. The default lower limit is 10 MΩ. The default upper limit is 1000 MΩ. Low glass impedance means the glass membrane — the sensing element in a pH sensor — is cracked or broken. High glass impedance means the membrane is aging and nearing the end of its useful life. High impedance can also mean the pH sensor is not completely submerged in the process liquid.

1. Check the sensor wiring, including connections in a junction box.

2. Verify that the sensor is completely submerged in the process liquid.

3. Verify that the software switch identifying the position of the preamplifier is properly set. See Section 7.4.

4. Check the sensor response in buffers. If the sensor can be calibrated, it is in satisfactory condition. To disable the fault message, reprogram the glass impedance limits to include the measured impedance. If the sensor cannot be calibrated, it has failed and must be replaced.

10.2.3 ADC Read Error

The analog to digital converter has probably failed.

1. Verify that sensor wiring is correct and connections are tight. Be sure to check connections at the junction box if one is being used. See Section 3.1 for wiring information.

2. Disconnect the sensor(s) and simulate temperature and sensor input. See Section 10.7 and 10.8.

3. If the transmitter does not respond to simulated signals, call the factory for assistance.

10.2.4 Ref Z Too High.

Ref Z Too High is an electrode fault message. Ref Z Too High means that the reference impedance exceeds the pro-

grammed Reference Fault Limit. A plugged or dry reference is the usual cause of a high reference impedance. High reference impedance also occurs if the sensor is not submerged in the process liquid or if inappropriate limits have been programmed into the transmitter.

The pH sensor is normally used with a high reference impedance. To disable the fault or warning diagnostic, program the reference impedance to a high value.

10.2.5 EE Buffer Overflow

EE Buffer Overflow means the software is trying to change too many background variables at once. Remove power from

the transmitter for about 30 seconds. If the warning message does not disappear once power is restored, call the factory for assistance.

10.2.6 EE Chksum Error

EE Chksum Error means a software setting changed when it was not supposed to. The EEPROM may be going bad. Call

the factory for assistance.

10.2.7 EE Write Error

EE Write Error usually means at least one byte in the EEPROM has gone bad. Try entering the data again. If the error

message continues to appear, call the factory for assistance.

MODEL Xmt-P SECTION 10.0

TROUBLESHOOTING

10.2.8 pH mV Too High

This message means the raw millivolt signal from the sensor is outside the range -2100 to 2100 mV.

1. Verify all wiring connections, including connections in a junction box.

2. Check that the pH sensor is completely submerged in the process liquid.

3. Check the pH sensor for cleanliness. If the sensor look fouled of dirty, clean it. Refer to the sensor instruction

manual for cleaning procedures.

10.2.9 No pH Soln GND

In the transmitter, the solution ground (Soln GND) terminal is connected to instrument common. Normally, unless the pH sensor has a solution ground, the reference terminal must be jumpered to the solution ground terminal.

HOWEVER, WHEN THE pH SENSOR IS USED WITH A FREE CHLORINE SENSOR THIS CONNECTION IS NEVER MADE.

10.2.10 Sense Line Open

Most Rosemount Analytical sensors use a Pt100 or Pt1000 RTD in a three-wire configuration (see Figure 10-3). The in and return leads connect the RTD to the measuring circuit in the transmitter. A third wire, called the sense line, is connected to the return lead. The sense line allows the transmitter to correct for the resistance of the in and return leads and to correct for changes in lead wire resistance with changes in ambient temperature.

1. Verify that all wiring connections are secure, including connections in a junction box.

2. Disconnect the RTD SENSE and RTD RETURN wires. Measure the resistance between the leads. It should

be less than 5Ω.

3. The transmitter can be operated with the sense line open. The measurement will be less accurate because

the transmitter can no longer compensate for lead wire resistance. However, if the sensor is to be used at approximately constant ambient temperature, the lead wire resistance error can be eliminated by calibrating the sensor at the measurement temperature. Errors caused by changes in ambient temperature cannot be eliminated. To make the warning message disappear, connect the RTD SENSE and RETURN terminals with a jumper.

10.2.11 Need Factory Cal

This warning message means the transmitter requires factory calibration. Call the factory for assistance.

10.2.12 Ground >10% Off

This warning message means there is a problem with the analog circuitry. Call the factory for assistance.

10.3 TROUBLESHOOTING WHEN NO FAULT MESSAGE IS SHOWING - TEMPERATURE

10.3.1 Temperature measured by standard was more than 1°C different from controller.

A. Is the standard thermometer, RTD, or thermistor accurate? General purpose liquid-in-glass thermometers, par-

ticularly ones that have been mistreated, can have surprisingly large errors. B. Is the temperature element in the sensor completely submerged in the liquid? C. Is the standard temperature sensor submerged to the correct level?

10.4 TROUBLESHOOTING WHEN NO FAULT MESSAGE IS SHOWING - HART

A. If the Model 375 or 275 Communicator software does not recognize the Model Xmt-P transmitter, order an

upgrade from Rosemount Measurement at (800) 999-9307. B. Be sure the HART load and voltage requirements are met.

1. HART communications requires a minimum 250 ohm load in the current loop.

2. Install a 250-500 ohm resistor in series with the current loop. Check the actual resistor value with an ohmmeter.

3. For HART communications, the power supply voltage must be at least 18 Vdc. See Section 2.4.

C. Be sure the HART Communicator is properly connected.

1. The Communicator leads must be connected across the load.

2. The Communicator can be connected across the power terminals (TB2).

D. Verify that the Model 375 or 275 is working correctly by testing it on another HART Smart device.

1. If the Communicator is working, the transmitter electronics may have failed. Call Rosemount Analytical for assistance.

2. If the Communicator seems to be malfunctioning, call Rosemount Measurement at (800) 999-9307 for assistance.
