SYSTEM DESCRIPTION

SAFETY MESSAGES

A complete magnetic flowmeter system consists of two components: the Rosemount Model 8732C microprocessor-based integral-mount magnetic flowmeter transmitter, and a Rosemount Model 8705 or 8711 flowtube.

The flowtube is installed in-line with process piping, either vertically or horizontally. Coils located on opposite sides of the flowtube create a magnetic field, and conductive liquid moving through the magnetic field generates a voltage that is detected by two electrodes.

The transmitter controls the generation of th e mag netic field and senses the voltage detected by the electrodes. Base d on the se n sed voltage, the transmitter calculates a flow rate and produces analog and frequency output signals proportional to this flow rate.

Procedures and instructions in this manual may requ ire spe cial precautions to ensure the safety of the perso nnel performi ng the operations. Refer to the safety messages listed at the beginning of each section before performing any operations.

PRE-INSTALLATION

Identify Options and Configurations

Hardware Switches

There are several pre-installation steps that make the installation process easier. They include identifying the options and configurations that apply to your application, setting the hardware switches if neces sary, and consideration of m ech anic al , electr ical , and envir on mental req u iremen ts .

Please remember that the flowtube liner is vulnerabl e to handli ng damage. Never place anything through the flowtube for the purpose of lifting or gaining leverage. Liner damage can render the flowtube useless.

Standard application of the Model 8732C includes a 4–20 mA output and control of the flowtube coils. Other applications may require one or more of the following configurations or options:

• Multidrop Communications

• Auxiliary Output

• Pulse Output

Additional options may also apply. Be sure to identify the options and configurations that apply to your situation, and keep a list of them nearby during the installation and configuration procedures.

The Model 8732C electronics board is equipped with three user-selectable hardware switches: Failure Alarm Mode, Output Power Source, and Software Lockout Mode. The standard configurations for these switches when shipped from the factory are as follows:

Failure Alarm Mode: High Output Power Source: Internal Software Lockout: Off

Definitions of these switches and their functions are provided below. If you determine that the settings must be changed, see Changing Hardware Switch Settings on page 2-3.

Failure Mode If the Model 8732C experiences a catastrophic failure in the electronics,

the current output can be driven high (22.50 mA) or low (3.75 mA). The switch is set in the High position when it leaves the factory.

Current Output Internally or Externally Powered

T ransmitter Security The Model 8732C has a switch that locks out any configuration changes

The Model 8732C 4–20 mA loop may be powered internally or by an external power supply. The Internal/External power supply switch determines the source of the 4–20 mA loop power. Transmitters leaving the factory are set in the Internal position.

The external power option is required for multidrop communications applications. A 10–30 V dc external supply is required, and the switch must be reset. For further information on 4–20 mA external power, see Connect 4–20 mA Loop External Power Source on page 2-20.

attempted on the transmitter. Any changes to the configuration are disallowed whenever the switch is in the On position. Ho wever, the flow rate indication and totalizer functions remain active.

With the switch in the On position, you may still access and review any of the operating parameters and scroll through the available choices, but no actual data changes are allowed.

The local operator interface (LOI) has a display lock function that will restrict any changes to the configuration via the LOI only. (This restriction applies to the totalizer functions as well.) This protection is intended to prevent accidental activation of the optical LOI in the field. Refer to page 3-5 for information about activating and deactivating the display lock function. The display lock is not on when the Model 8732C leaves the factory.

Changing Hardware Switch Settings

FIGURE 2-1. Model 8732C Electronics Board and Hardware Switches.

In most cases, it is not necessary to change the setting of the hardware switches. If you need to change the switch settings, complete the steps outlined below:

NOTE

The hardware switches are located under the cover opposite the terminal block. Because changing their settings requires opening the electronics housing, make every attempt possible to carry out these procedures away from the plant environment to protect the electronics.

1. Disconnect power to the transmitter.

2. Unscrew and remove the electronics cover.

3. Identify the location of each switch (see Figure 2-1).

4. Change the setting of the desired switches with a small screwdriver.

5. Reinstall and tighten the electronics cover.

Mechanical Considerations

The mounting site for the Model 8732C Integral Mount Transmitter should provide enough room for secure mounting, easy access to the conduit ports, full opening of t he transmit ter covers, and eas y readability of the local operator interface (LOI) screen (see Figure 2-2). The electronics housing can be rotated on the flowtube in 90° increments. This can be done by loosening the four mounting bolts on the bottom of the housing, rotating the housing, and reinstalling the bolts. Be sure the surface is clean and there is not a gap when returning the housing to its original position.

The LOI can also b e ro tated i n 90 ° inc remen ts. Th is shou ld b e pe rf ormed prior to installing the ma gnetic flowmeter system. Re fer to LOI Rotation on page 3-3 for additional information.

Installation

Electrical Considerations

Before making any electrical connections to the Model 8732C, consider the following standards and be sure to have proper power supply, conduit, and other accessories.

Conduit Connections The Model 8732C Integral Mount Magnetic Flowmeter Transmitter

has two ¾–inch NPT conduit connections. If one of these ports is not being used, it must be sealed with a conduit seal. In some cases, conduits may also require drainage if moisture could build up in the line.

Transmitter Input Power The Model 8732C Transmitter is designed to be powered by voltages

ranging from 90 to 250 V ac (50 to 60 Hz) or 15–30 V dc. Units powered with an ac power supply should be connected to standard ac connections for 90 V ac or 250 V ac. Units powered by a 15–30 V dc power supply have special considerations.

DC Power Requirements Units powered with 15–30 V dc may draw up to 2 amps of current. As a

result, the input power wire must meet certain gauge requirements. Table 2-1 and Table 2-2 show the maximum wire length for corresponding supply voltages, wire gauges, and wire type.

Environmental Considerations

INSTALLATION PROCEDURES

Handling

To ensure maximum transmitter life, avoid excessive heat and vibration. Typical problem areas include high-vibration lines with integrally mounted transmitters, warm-climate installations in direct sunlight, and outdoor installations in cold climates.

Because the Model 8732C System requires external power, access to a suitable power source must be ensured.

Overheating will damage the flowtube. Do not encapsulate the flowtube with heating elements.

These installation tasks provide detailed mechanical and electrical installation procedures.

All parts should be handled carefully to prevent damage. Whenever possible, transport the system to the installation site in the original shipping containers. The flowtube is shipped with end covers to protect it from mechanical damage and normal unrestrained distortion. End covers should not be removed until just before installation. Keep shipping plugs in conduit connections until conduits are connected and sealed.

All flowtube liners are vulnerable to handling damage. Never place anything through the flowtube for the purpose of lifting or gaining leverage. Liner damage can render the flowtube useless.

FIGURE 2-4. Model 8705 Flowtube Support for Handling.

Flanged flowtubes have different lifting and transportation guidance. Refer to Figure 2-4 for correct handling techniques. Wafer style flowtubes have no special lifting directions, however every precaution should be taken to avoid liner damage.

Flowtube Mounting

Physical mounting of a flowtube is similar to installing a typical section of pipe. Only conventional tools, equipment, and accessories (such as bolts, gaskets, and grounding hardware) are required.

Calibration Rosemount magnetic flowmeter systems are wet-calibrated at the

factory and need no further calibration during installation.

Upstream/Downstream Piping To ensure specific accuracy over widely varying process conditions,

install the flowtube with a minimum of five straight pipe diameters upstream and two pipe diameters downstream from the electrode plane, as shown in Figure 2-5. This flowtube placement is usually adequate to allow for disturbances created by elbows, valves, and reducers.

Installation

Flowtube Orientation

Vertical Installation Vertical installation allows upward process fluid flow and is generally

preferred. Upward flow keeps the cross-sectional area full, regardless of flow rate. Orientation of the electrode plane is unimportant in vertical installations.

NOTE

As shown in Figure 2-6, avoid downward vertical flows where back pressure is inadequate to ensure that the flowtube remains full.

FIGURE 2-6. Vertical Flowtube Orientation.

Flow

Horizontal Installation Horizontal installation should be restricted to low piping sections that

are normally full. Orient the electrode plane to within 45 degrees of horizontal in horizontal installations. A deviation of more than 45 degrees of horizontal would place an electrode at or near the top of the flowtube–making it more susceptible to insulation by air or entrapped gas at the top of the flowtube.

An inclined installation, as shown in Figure 2-8, is an acceptable installation technique. This tends to keep the cross-sectional area full.

NOTE

As shown in Figure 2-8, avoid declining installations where back pressure is inadequate to ensure that the flowtube remains full.

Flange Bolts

Flowtube sizes and torque values for Class 150 and Class 300 flanges are listed in T able 2-3. Tighten flange bolts in the incremental sequence shown in Figure 2-11.

Model 8705 Correct flange bolt tightening is crucial for proper flowtube operation and

life. All bolts must be tightened in the proper sequence to the specified torque limits. Failure to observe these instructions could result in severe damage to the flowtube lining and possible flowtube replacement.

Always check for leaks after tightening flange bolts. All flowtubes require a second torquing 24 hours after initial flange bolt tightening.

Installation

Model 8711 For Model 8711, the flowtube inside diameter should be centered with

respect to the inside diameter of the adjoining upstream and downstream piping. This will ensure the flowmeter achieves its specified accuracy. Mounting bolts supplied with 0.15 through 1-inch (4–25 mm) line sizes are specifically sized to properly align these flowtubes with the flange configurations specified. For 1.5 through 8-inch (40–200 mm) line sizes, two centering rings are supplied for alignment purposes. Place the centering rings over the flowtube using the following instructions as a reference. If you received two centering sleeves, follow the steps described under Alignment with Centering Sleeves.

Alignment with Centering Rings

1. Insert the two studs for the bottom side of the flowtube between the pipe flanges.

2. Place the two centering rings over each end of the flowtube.

3. Place the flowtube between the flanges. Make sure that the centering rings are properly placed in the studs. The studs should be aligned with the markings on the rings that correspond to the flange you are using.

4. Insert the remaining studs, and install the washers and nuts.

5. Tighten the nuts to the specifications listed in Table 2-4.

NOTE

On the 4- and 6-inch PN 10–16, the installer will need to insert the flowtube with rings first and then insert the studs. The slots on this ring scenario are located on the inside of the ring.

OPTIONS, CONSIDERATIONS, AND PROCEDURES

Connect 4–20 mA Loop External Power Source

FIGURE 2-25. 4–20 mA Loop Power Connections.

If your application of the Model 8732C includes an externally powered 4–20 mA loop, auxiliary output control or pulse output, certain requirements may apply in addition to those previously listed. Satisfy these requirements before attempting to install and operate the Model 8732C.

The 4–20 mA output loop is powered either internally or externally.

Internal

The loop may be powered from the transmitter itself. Resistance in the loop must be 1,000 ohms or less. If a HART-based communicator or a distributed control system (DCS) is used, it must be connected across a minimum of 250 ohms resistance in the loop.

External

External power must be supplied if the Model 8732C is to be used in a multidrop installation (see Multidrop Communications on page 4-18). A 10–30 V dc power source is required. If a HART-based Communicator or DCS is used, it must be connected across a minimum of 250 ohms resistance in the loop.

If your application uses the external power option for the 4–20 mA loop, complete the following steps to connect the power source to the transmitter:

1. Ensure that the power source and connecting cable meet the requirements outlined above and in Electrical Considerations on page 2-5.

2. Turn off the transmitter and analog loop power sources.

3. Run the power cable into the transmitter.

QUICK START-UP

Once the magnetic flowmeter system is installed and communication is established, final configuration of the transmitter must be completed. You may perform these functions with the LOI (Section 3: Local

Operator Interface) or HART Communicator (Appendix A: HART Communicator). Specific instructions regarding these functions are

provided in Section 4: Transmitter Functions. To initiate a basic flowmeter system start-up, only two parameters

are required:

1. Set Units

2. Analog Output Range

If your application of the magnetic flowmeter system involves more advanced functions such as multidrop or pulse output, additional configuration steps may be required to enable full functionality. See Section 4: Transmitter Functions.

Installation

Installation Check and Guide

Use this guide to check new installations of Rosemount Magnetic Flowmeter Systems that appear to malfunction. For detailed troubleshooting instructions, see Section 5: Troubleshooting.

Before You Begin

Be sure that power to your system is off before beginning these checks.

Transmitter

1. Check for correct flowtube calibration number entered in the software. (The calibration number is listed on the flowtube nameplate.)

2. Check for correct flowtube line size entered in the software. (The line size value is listed on the flowtube nameplate.)

3. Check that the analog range of the transmitter matches the analog range in the control system.

4. Check that the forced analog output of the transmitter produces the correct output at the control system.

Flowtube

1. For horizontal flow installations, ensure that the electrodes are in a plane such that they remain covered by process fluid.

2. For vertical or inclined installations, ensure that process fluid is flowing up into the flowtube to keep the electrodes covered by process fluid.

3. Ensure that the grounding straps on the flowtube are connected to grounding rings, lining protectors, or the adjacent pipe flanges. Improper grounding will cause erratic operation of the system.

Process Fluid

1. Process fluid conductivity should be 5 centimeter, minimum.

2. Process fluid must be free of air and gasses.

3. Flowtube should be full of process fluid.

PROCESS LEAK PROTECTION (MODEL 8705 ONLY)

The Model 8705 Flowtube housing is fabricated from carbon steel to perform two separate functions in the flowtube design. First, it provides shielding for the flowtube magnetics so that external disturbances cannot interfere with the magnetic field and thus affect the flow measurement.

Second, it provides the physical protection to the coils and other internal components from contamination and physical damage that might occur in the industrial environment. The housing is completely welded, and the joints contain no gaskets; the totally leak-free enclosure protects the internal components, even in the most demanding installations.

2-23

Page 36

Rosemount Model 8732C Integral Mount Magnetic Flowmeter System

Process Leak Containment

FIGURE 2-27. Sealed Electrode Compartment–Standard Configuration.

As shown in Figure 2-27, the standard configuration divides the housing into three separate compartments: one for each electrode and one for the coils. The electrodes are separated from the rest of the internal components and the coils.

If a damaged liner allows process fluid to migrate behind the electrode seals, the fluid is contained in the electrode compartment. The sealed electrode compartment prevents the process fluid from entering the coil compartment where it would damage the coils and other internal components.

The electrode compartments are designed to contain the process fluid at full line pressure. An O-ring sealed cover provides access to each of the electrode compartments from outside the flowtube; drainports are provided in each cover for the removal of fluid.

The electrode compartment could contain full line pressure and it must be depressurized before the cover is removed. Removing the cover before depressurizing may result in death or serious injury.

Fused Glass

Ground Electrode Port

If it is necessary to capture any process fluid leaka ge for fugit ive emission control, connect the appropriate piping to the drainports and provide for proper disposal as shown in Figure 2-27.

The second configuration uses a completely welded coil housing but does not provide the separate electrode compartment or external electrode access of the standard construction. This housing configuration is identified by a “W1” in the option code of the model number.

Relief Valves

FIGURE 2-28. Relief Valve Venting.

Housing configuration “W1” provides a relief valve in the housing to prevent possible overpressuring caused by damage to the lining or other situations that might allow process pressure to enter the housing. The relief valve will vent when the pressure inside the flowtube housing exceeds 5 psi. Additional piping (provided by the user) may be connected to this relief valve to drain any process leakage to safe containment (see Figure 2-28). In the event of a process leak, these models will not protect the coils or other sensitive areas of the flowtube from exposure to the pressure fluid.

Field-Removable Electrodes

The field-removable electrode option allows the user to remove the electrode assembly with the flowtube still mounted in the line. Frequently, this option will be used for cleaning the electrode head when coating is of concern.

The flowtube should be drained of any process fluid prior to disassembly of electrodes. Care should be taken when handling products, or electrodes having been in contact with products of a corrosive nature, to avoid per so n al i nj u ry. Take care to avoid rotating the electrode whe n removing it to avoid leakage. Some resistance may be experienced due to the tight o-ring fit.

Remove the Electrode Assembly

Use the following procedure to remove the electrode assembly from the flowtube.

1. Loosen and remove the screws that secure the electrode cover.

2. Remove the electrode cover and o-rings. It is generally

recommended that new o-rings be installed upon reassembly.

3. Loosen and remove the screw that secures the signal wire to the electrode.

4. Remove the retaining nut.

5. Take the electrode from the electrode housing by pulling it out, with firm pressure, along the axis of the electrode.

Replace the Electrode Assembly

Use the following procedure to replace the electrode assembly into the flowtube.

1. Lubricate the o-rings.

2. Install the o-rings on the electrode.

3. Insert the electrode assembly into the electrode housing.

4. Secure the electrode into the housing with the retaining nut. Tighten the retaining nut to 15 in/oz of torque.

5. Secure the signal wire to the electrode with a screw.

6. Install the o-rings into the electrode cover.

7. Secure the electrode cover to the flowtube with the screws.

REVIEW VARIABLES

Before operating the Model 8732C in an actual installation, review all of the factory set configuration data to ensure that they reflect the current application.

Review Review the flowmeter configuration parameters set at the factory to

HART Fast Keys

1, 5

ensure accuracy and compatibility with your particular application of the flowmeter.

NOTE

If you are using the LOI to review variables, each variable must be accessed as if you were going to change its setting. The value displayed on the LOI screen is the configured value of the variable.

If you need to make any changes to flowmeter configuration data, see Basic Configuration on page 4-4 for additional information.

CHECK OUTPUT VARIABLES

Next, check the transmitter output. Model 8732C digital outputs include: flow rate (PV), pulse output, measure gross total, measure net total, and measure reverse total. The settings should be reviewed to ensure that the flowmeter is operating properly.

Process Variables

HART Fast Keys

1, 1

The Process Variables for the Model 8732C provide the flowmeter output. They measure flow in several ways that reflect your needs and the configuration of your flowmeter.

LOI

Display Setup

When commissioning a flowmeter, review each process variable, its function, and output. If you suspect a problem with the digital outputs, you may need to reconfigure the transmitter or check the troubleshooting table in Section 5: Troubleshooting.

PV – Process Variable is the actual configured flow rate in the line. On the bench, the PV value should be zero. Check the units on the PV to make sure they are configured correctly. If the units format is not correct, see Units on page 4-4.

Puls Out – Pulse Output provides the actual pulse reading from the meter if your transmitter is configured for pulse output.

Measure gross totl – Measure Gross Total provides a reading of the total forward flow since the totalizer was last reset. The totalizer value should be zero during commissioning on the bench, and the units should reflect the volume units of the flow rate. If the totalizer value is not zero, it may need to be reset (see Totalizer Display on page 4-11).

Measure net totl – Measure Net Total provides a reading of the net totalized flow in the forward direction. The net totalize value can be reset using the HART Communicator (1, 1, 4, 6) or the LOI.

Measure reverse totl – Measure Reverse Total provides a reading of the total flow of process fluid in the reverse direction.

• Liters/Min • Meters/Sec

• ImpGal/Min • Liters/Sec

• CuMeter/Min • Special

The maximum flow rate information is not updated as the available units appear, but only after the data are entered. The maximum flow rate on the second line of the display is for informational purposes, and cannot be changed directly by the user.

If the transmitter is totalizing, the numerator of the unit of measure is used by the transmitter as the volumetric unit for totalization and pulse output scaling. For example, if gal/min is selected, the Model 8732C totalizes and provides a pulse output in gallons.

Line Size Line Size (tube size) must be set to match the actual flowtube

connected to the transmitter. The size is set at the factory before the flowtube is shipped. If a value is entered from a control system or HART Communicator that does not match one of these figures, the value will be rounded to match the nearest choice.

The tube size choices available are as follows:

0.15, 0.30, 0.50, 1, 1.5, 2, 3, 4, 6, 8, 10, 12, 14, 16, 18, 20, 24, 30, 36, 42, 48, 54, 60 (inches).

flowtubes calibrated at the Rosemount factory. It provides detailed calibration information to the Model 8732C. This number is set at the factory before the flowmeter is shipped.

Upper Range Value Upper Range Value (URV) is preset to 30 ft/s at the factory. The units that

appear will be the same as those selected under the units parameter. The URV (20 mA point) can be set for any forward or reverse flow rate.

Flow in the forward direction is represented by positive values; flow in the reverse direction is represented by negative values. The UR V can be any value from –30 ft/s to +30 ft/s, as long as it is at least 1 ft/s from the Lower Range Value (LRV)(4 mA point). The URV can also be set to a value less than the LRV, which would cause the transmitter analog output to operate in reverse, with the electrical current increasing for lower (or more negative) flow rates.

SPECIAL UNITS CONFIGURATION

The Model 8732C provides a selection of standard units configurations that meet the needs of most applications (see Units on page 4-4). If, however, your application has special needs and the standard configurations do not apply, the Model 8732C provides the flexibility to configure the transmitter in a custom-designed units format.

NOTE

For flowtubes larger than 36 inches (900 mm), line size must be selected prior to configuration of special units. If special units are configured first, the communication interface may not display the correct flow rate.

To configure a special unit, set values for each function listed below.

Volume Unit Volume Units enables you to display the volume unit format to which

ANALOG OUTPUT CONFIGURATION

The standard 4–20 mA analog output can be configured to meet the special requirements of your application. In the standard configuration, a 4 mA output (LRV) corresponds to 0.0 ft/s in the line, while a 20 mA output (URV) corresponds to a maximum flow of 30 ft/s. The 4 and 20 mA output points can be changed to any value between –30 ft/s and 30 ft/s. The minimum allowable range between them is 1 ft/s.

NOTE

The minimum span between the analog output range (URV) and analog output zero (LRV) is 1 ft/s.

(or span) between the URV and LRV. Under normal circumstances, the LRV should be set to a value near the minimum expected flow rate to maximize resolution. LRV must be between –30 ft/s to 30 ft/s.

NOTE

The LRV can be set to a value greater than the URV, which will cause the analog output to operate in reverse. In this mode, the analog output will increase with lower (more negative) flow rates.

Example

If the URV is greater than the LRV, the analog output becomes 3.9 mA when the flow rate falls below the selected 4 mA point.

If the URV is less than the LRV, the analog output becomes 3.9 mA when the flow rate rises above the selected 4 mA point.

The minimum allowable span between the URV and LRV is 1 ft/s. Do not set the LRV within 1 ft/s of the 20 mA point. For example, if the URV is set to 15.67 ft/s and if the desired URV is greater than the LRV, then the highest allowable LRV would be 14.67 ft/s. If the desired URV is less than the LRV, then the lowest allowable analog zero setting would be 16.67 ft/s.

Use the following steps to complete this function.

1. Set the loop to manual, if necessary.

2. Connect a precision ammeter to the 4–20 mA loop.

3. Initiate the Output Trim function with the LOI or HART Communicator.

4. Enter the 4 mA meter value when prompted to do so.

5. Enter the 20 mA meter value when prompted to do so.

6. Return the loop to automatic control, if necessary.

The 4–20 mA trim is now complete. You may repeat the 4–20 mA trim to check the results, or use the analog output test.

DIGITAL OUTPUT

Pulse Output Scaling equates one transistor switch closure pulse to a selectable number of volume units. The volume unit used for scaling pulse output is taken from the numerator of the configured flow units. For example, if gal/min had been chosen when selecting the flow rate unit, the volume unit displayed would be gallons.

NOTE

The scaled pulse output is designed to operate between 0 and 1000 Hz. The electronics will not accept a conversion factor that would result in a pulse frequency outside that range. The minimum conversion factor value is found by dividing the uppe r range value (in u nits of volume p er second) by 1000 Hz.

When selecting pulse output scaling, remember that the maximum pulse rate is 1000 Hz. With the 110 percent overrange capability, the absolute limit is 1100 Hz. For example, if you want the Model 8732C to pulse every time 0.01 gallons pass through the flowtube, and the flow rate is 1000 gal/min, you will exceed the 1000 Hz full-scale limit:

---------------------------------------------------------------------------

60 sec/min 0.01 gal/pulse×

1000 gal/min

1666.65 Hz=

The best choice for this parameter depends upon the required resolution, the number of digits in the totalizer, the extent of range required, and the maximum counter input frequency.

NOTE

When totalizing on the LOI, the maximum total value is 1,000,000,000.

Auxiliary Output Control In lieu of the pulse output on the digital terminals, an Auxiliary

Output Control is available to indicate a reverse flow or zero flow condition. The two terminals are actually a transistor switch closure, which must be externally powered.

Reverse Flow Enable

This choice activates the switch closure with a reverse flow. A forward flow is defined by the flow direction arrow on the flowtube. This also enables the totalizer to count in the reverse direction.

No Flow Enable

This choice activates the switch closure whenever the flow rate drops below the low flow cutoff.

TOTALIZER CONFIGURATION

The totalizer tracks total flow in the process line. You can start, stop, or reset the totalizer as well as configure it to present the data specific to your application on the LOI display.

Totalizer Display On the LOI, the Totalizer Display allows you to choose the desired

HART Fast Keys

LOI

Display Setup

format for indicating the totalized values. You may choose either forward-reverse or net-gross for displaying totalized values. On the HART Communicator, Gross, Net, and Reverse values are always available.

Forward-Reverse

Forward-Reverse shows both the forward and reverse totalized values, updating continuously. You must choose reverse flow enable to allow totalizing in the reverse direction.

These values cannot be reset by using the totalizer reset button. Reset them by doing one of the following:

• Change the pulse scaling.

• Change the tube size.

• Change the units.

• Power down a transmitter that is not equipped with the non-volatile totalizer option.

Net-Gross

Net-Gross shows both net and gross total values. It updates contin uously. The net value can be reset by the operator. The gross value cannot be reset by using the

→ button. Reset it indirectly by d oing one of the foll owing:

• Change the pulse scaling.

• Change the tube size.

• Change the units.

• Power down a transmitter that is not equipped with the non-volatile totalizer option.

To prevent an operator from accidentally resetting the gross value, the Software Protect jumper on the electronics board should be in the ON position. This action does not block the functions of the

E ← and →

buttons for starting and stopping or reading and resetting the totals.

Example

If you had a batch-type process, you would use the net value to measure each batch and then have the operator reset it. In addition, the gross value would keep track of a period of production (e.g., eight hour shift, day, week, month). The gross value could be reset by cycling power to the unit (if not equipped with a backed totalizer battery) or changing one of the parameters described above.

• Time limit (0 to 256 seconds)

Detailed Setup

When ON is selected, the Model 8732C output is derived using a running average of the individual flow inputs. This average is updated at the rate of 12 samples per second regardless of the selected coil drive mode. The three parameters that make up Signal Processing Control: Number of samples, maximum percent limit, and time limit. They are described individually below.

Detailed Setup

Detailed Setup

The number of samples function sets the number of previous inputs used to calculate the average value. Because the output stage of the Model 8732C circuit is updated twelve times each second, regardless of 6 or 30 Hz coil drive mode, the factory preset value of 90 samples equates to 7.5 seconds. For example, if you select a sample number of 120, the response time of the system will be 10 seconds (120 samples

÷ 12 samples per second). A sug gested nominal number of

90 samples is a good starting point for most applicable process fluids.

0 to 100 Percent

The maximum percent limit is a tolerance band set up on either side of the running average. The percentage value refers to deviation from the running average. For example, if the running average is 100 gal/ min, and a 2 percent maximum limit is selected, then the acceptable range is from 98 to 102 gal/min.

Values within the limit are accepted while values outside the limit are analyzed to determine if they are a noise spike or an actual flow change.

This parameter forces the output and running average values to the new value of an actual flow rate change that is outside the percent limit boundaries. It thereby limits response time to flow changes to the time limit value rather than the length of the running average.

For example, if the number of samples selected is 120, then the response time of the system is 10 seconds. In some cases this may be unacceptable. By setting the time limit, you can force the Model 8732C to clear the value of the running average and re-establish the output and average at the new flow rate once the time limit has elapsed. This parameter limits the response time added to the loop. A suggested time limit value of 2 seconds is a good starting point for most applicable process fluids. The selected signal processing configuration may be turned ON or OFF to suit your needs.

CALIBRATION

Gain (Electronics) Trim Gain Trim is the function by which the fact ory calibrates the tr ansmitter.

HART Fast Keys

LOI

1, 2, 4, 3

Transmitter Trim

This procedure is rarely needed by customers. It is only necessary if you believe the Model 8732C is no longer acc urate. It must be perfor med with the coil drive mode set to 6 Hz and with a nomin al flowt ube calibra tion number stored in the memory.

Attempting an electronics trim without a Model 8714D may result in an inaccurate transmitter, or a “DIGITAL TRIM FAILURE” message may appear. If this message occurs, no values were changed in the transmitter . Simply power down the Model 8732C to clear the message. If the trim was completed or no error message appears, correction requires a Model 8714D.

To simulate a nominal flowtube with the Model 8714D, you must change the following parameters in the Model 8732C:

• Tube Calibration Number:1000015010000000

• Units: ft/s

• Upper Range Value: 20 mA = 30.00 ft/s

• Lower Range Value: 4 mA = 0 ft/s

• Coil Frequency: 6 Hz

The instructions for changing these parameters are located in the parameter descriptions in this section. Set the loop to manual, if necessary, before you begin. Complete the following steps:

1. Power down the transmitter.

2. Connect the transmitter to a Model 8714D Flowtube Simulator.

3. Power up the transmitter with the Model 8714D connected and read the flow rate. The electronics need about a 30-minute warm-up time to stabilize.

4. The flow rate reading after warm-up should be between

29.97 and 30.03 ft/s.

5. If the reading is within the range, return the transmitter to the original configuration parameters.

6. If the reading is not within this range, initiate an electronics trim with the LOI or HART Communicator. The gain trim takes about 6 minutes to complete. No transmitter adjustments are required.

MULTIDROP COMMUNICATIONS

FIGURE 4-2. Typ ical Multid rop Network.

Multidrop configuration refers to the connection of seve ral transmitters to a single communications transmission line. Communication between the HART Communicator and the transmitters takes place digitally with the analog output of the transmitters deactivated. Using the HART communications protocol, up to 15 transmitters can be connected on a single twisted pair of wires or over leased phone lines.

The use of a multidrop installation requires consideration of the update rate necessary from each transmitter, the combination of transmitter models, and the length of the transmission line. Multidrop installations are not recommended where intrinsic safety is a requirement. Communication with the transmitters can be accomplished with commercially available Bell 202 modems and a host implementing the HART protocol. Each transmitter is identified by a unique address (1-15) and responds to the commands defined in the HART protocol.

Figure 4-2 shows a typical multidrop network. This figure is not intended as an installation diagram. Contact Rosemount product support with specific requirements for multidrop applications.

The HART Communicator can test, configure, and format a multidropped Model 8732C in the same way as it can a Model 8732C in a standard point-to-point installation.

NOTE

The Model 8732C is set to poll address zero at the factory, allowing it to operate in the standard point-to-point manner with a 4–20 mA output signal. To activate multidrop communication, the transmitter poll address must be changed to a number between 1 and 15. This change deactivates the 4–20 mA analog output, sending it to 4 mA. It also disables the failure mode alarm signal.

If it detects an address other than 0, the communicator finds each device in the loop and lists them by poll address and tag number. Use the action keys to scroll through the list and select the transmitter with which you need to communicate.

If a single connected device has an address other than zero and auto polling is off, the device will not be found.

Troubleshooting

Flowtube Troubleshooting Procedures

The following tests can check Models 8705 or 8711 flowtubes in line and full of process material. The tests allow you to determine whether or not the flowtube needs to be removed from the process. The transmitter must be removed to conduct these tests. Use the following procedure to remove the transmitter:

Transmitter Removal Procedure 1. Remove power to the transmitter.

2. Remove the electronics compartment cover.

3. Carefully unhook the wires at the base of the electronics stack.

4. Remove the four bolts that attach the flowtube to the transmitter.

5. Carefully remove the housing, ensuring not to snag any wires.

6. Leave the wiring harness connected to the flowtube terminal block.

T ransmitter Assembly Procedure Use the following procedure to reassemble the transmitter:

1. Carefully attach the electronics stack to the housing.

2. Secure the four bolts that attach the flowtube to the transmitter.

3. Carefully hook up the wires at the base of the electronics stack .

4. Attach t he electronics compartment cover.

5. Restore power to the transmitter.

TABLE 5-3. Magnetic Flowmeter Troubleshooting Chart.

Test A–Flowtube Coil

Step 1 Step 2 Step 3

Remove transmitter. Take all readings across flowtube terminals.

Test B– Coil Shield to Coil

Step 1 Step 2 Step 3

Remove transmitter. Take all readings across flowtube terminals.

Test C– Electrode Shield Resistance

Step 1 Step 2 Step 3

Remove transmitter. Take all readings across flowtube terminals. Test with process in the flowtube (either in flowing or non-flowing condition .)

Test D– Positive to Negative Electrode

➤

Measure the resistance across wires 1 and 2 going to the flowtube, using the lowest ohms scale. The reading should be between 2 and 18 V.

Measure the resistance from the coil shield (ground) to wires 1 and 2 using the highest ohms scale. Bot h read ing s should be overrange.

Measure the resistance from wire 17 to 18 and 17 to 19. This reading will change as you hold the leads on the wires, so use the initial reading. These readings sh oul d bot h be cl os e to each other.

➤

A reading outside this ra n ge in d ica te s that the coils or cables are open or shorted.

Any reading on the scale indicates that the coils are shorted to the housin g.

A reading less than 100 kV indicates a possible shorted electrode. A high reading indicates a possible coated electrode, nonco nductive process, or electrode not in contact with the process. A stable reading indicates a shorted electrode.

Step 1 Step 2 Step 3

Remove transmitter. Take all readings across flowtube terminals. Test with process in the flowtube (either in flowing or non-flowing condition .)

➤

Measure the resistance between wires 18 and 19. This r eading sho uld be in t he range between 100 kV and 600 kV.

➤

An overrange reading indicates a coated electrode, nonco nductive process, or electrode not in contact with the process.

Appendix

A HART Communicator

INTRODUCTION

SAFETY MESSAGES

This appendix provides basic communicator information on the HART Communicator Model 275 when used with a Model 8732C Integral Mount Magnetic Flowmeter System.

Included in this appendix are a menu tree, a table of fast key sequences, and information on using the HART communicator.

For more complete information on the HART Communicator, refer to the HART Communicator Product Manual 00809-0100-4275.

This brief appendix will familiarize you with the HART Communicator but is not meant to replace the HART Communicator product manual.

Explosions could result in death or serious injury:

• Verify that the operating atmosphere of the flowtube and transmitter is consistent with the appropriate hazardous locations certifications.

• Do not remove the transmitter cover in explosive atmospheres when the circuit is alive.

• Do not make connections to the HART Communicator’s serial port or NiCad recharger jack in an explosive atmosphere.

• Both transmitter covers must be fully engaged to meet explosion-proof requirements.

Failure to follow safe installation and servicing guidelines could result in death or serious injury:

• Make sure only qualified personnel perform these procedures.

• Do not perform any service other than those contained in this manual unless qualified.

CONNECTIONS AND HARDWARE

FIGURE A-2. Rear Connection Panel with Optional NiCad Recharger Jack.

Optional NiCad Recharger Jack

The HART Communicator exchanges information with the transmitter from the control room, the instrument site, or any wiring termination point in the loop. The HART Communicator should be connected in parallel with the transmitter. Use the loop connection ports on the rear panel of the HART Communicator (see Figure A-2). The connections are non-polarized.

Do not make connections to the serial port or NiCad recharger jack in an explosive atmosphere. Before connecting the HART Communicator in an explosive atmosphere, make sure the instruments in the loop are installed in accordance with intrinsically safe or nonincendive field wiring practices.
