SYSTEM OVERVIEW

UNPACKING THE HART TRI-LOOP

Figure 2-2 illustrates an installation where a Tri-Loop has been added to a Model 3095 MV installation.

The Tri-Loop design allows three different rail mounting options: asymmetrical 32mm G rail, symmetrical 35 3 7.5 mm top hat rail, and symmetrical 35 3 15 mm top hat rail. Since the Tri-Loop is designed for non-hazardous locations, the Tri-Loop can only be installed on the safe side of an IS barrier.

In this type of installation, the Model 3095 MV is configured to output HART Burst Command 3. The Tri-Loop converts each burst update to a corresponding analog value for up to three process variables. Any of the Model 3095 MV process variables can be provided via the Tri-Loop (DP, AP, GP, PT, or flow).

For each desired analog output, a separate pair of wires is installed from the Tri-Loop to the control room. However, Channel 1 wires must be installed and powered for the Tri-Loop to operate.

The initial Model 3095 MV analog output is not altered by the Tri-Loop installation.

When custom configuration Tri-Loops are shipped, the filled-out configuration data sheet (CDS) is included in the box. If the CDS is separated from the configured Tri-Loop, the serial number on the side of the Tri-Loop can be matched with the serial number written on the CDS. A label is also printed on the side of the Tri-Loop identifying configuration information.

Installation

Initial Inspection

Model 3095 MV (or HART Multivariable Device)

Alarms

1. Place the shipping containers on a secure bench and open them, taking care not to damage the contents.

2. Review the packing list to verify that all equipment was received.

3. Inspect the equipment and report any shipping damage to the carrier.

Before mounting the Tri-Loop in the control room, the Model 3095 MV or HART Multivariable device must first be installed. Refer to the Model 3095 MV product manual (00809-0100-4716) for information on installing the Model 3095 MV.

Tri-Loops are configured with all channels to alarm in the same direction. Alarm direction is configured at the factory, and cannot be changed in the field. In addition, all Tri-Loop channels will alarm if a Tri-Loop detects a sensor malfunction in the attached device.

Tri-Loops are ordered according to the desired alarm direction:

Tri-Loop Version Part Number

High Alarm Tri-Loop 03095-0810-0001 Low Alarm Tri-Loop 03095-0810-0002 High Alarm Tri-Loop, Custom

Configuration Low Alarm Tri-Loop, Custom

Configuration

03095-0810-0003

03095-0810-0004

Failure Mode Ala rm vs. Saturation Output Values

The failure mode alarm output levels differ from the output values that occur when the measured value is outside the range points. When the measured value is outside the range points, the analog output continues to track the input value until reaching the saturation value listed below; the output does not exceed the listed saturation value regardless of the measured value. For example, for values outside the 4–20 range points, the output saturates at 3.9 mA or 20.8 mA.

When the Tri-Loop diagnostics detect a Tri-Loop failure or a Model 3095 MV malfunction, the analog outputs are set to an alarm value that differs from the saturation value to allow for proper troubleshooting.

NOTE

The output values listed below can be altered by an analog output trim procedure.

Level

Low 3.9 mA < 3.75 mA

High 20.8 mA > 21.75 mA

4–20 mA

Saturation Value

4–20 mA

Alarm Value

NOTE

If a Tri-Loop channel sets a range different than the attached device, the Tri-Loop range will be used.

For example, if a Model 3095 MV sets the primary variable to DP with a range of 0–250 inH

0, and the Tri-Loop Configurator sets

Tri-Loop channel 1 to receive this DP variable but enters a range of 0–100 inH20, the Tri-Loop will use the 0–100 inH20 range.

INSTALLATION CONSIDERATIONS

MECHANICAL CONSIDERATIONS

FIGURE 2-3. DIN Rail Mounting Options.

• Install the Tri-Loop in a location where it will be within the operating temperature specification of 50 to 104 °F (10 to 40 °C).

NOT

• A Tri-Loop can

be installed in hazardous areas.

• Wiring need not be shielded, but twisted pairs should be used for best results. Wiring should be between 24–12 AWG (solid or stranded) and not exceed 1,000 feet (305 meters).

The Tri-Loop may be rail mounted on any of the DIN rails shown in Figure 2-3. Simply snap the Tri-Loop onto the rail in the desired location.

INSTALLATION EQUIPMENT

INSTALLATION PROCEDURE

1. Review Installation Considerations

2.Mount Tri-Loop on DIN Rail

The following equipment and tools are not provided with the HART Tri-Loop.

• Installation tools

• Wire between the control room and the Tri-Loop

• Wire between the Model 3095 MV and the Tri-Loop

• Power supply

• IS Barrier

1. Review the installation considerations described on pages 2-4 through 2-5 in this chapter to determine the location for the HART Tri-Loop.

Explosions can cause death or serious injury. The HARTTriLoop is designed for installation in ordinary locations only. Do NOT install the HART Tri-Loop in hazardous locations.

2. Mount the HART Tri-Loop on any of the following DIN rails:

• asymmetrical 32mm G rail,

• symmetrical 35 3 7.5 mm top hat rail

• symmetrical 35 3 15 mm top hat rail.

3. Wiring

3. Make wiring connections (see Figure 2-6).

NOTES

• Wiring need not be shielded, but twisted pairs should be used for best results.

• To ensure communication, wiring should be between 24–12 AWG (solid or stranded) and not exceed 1,000 feet (305 meters).

a. Run wire from Tri-Loop Channel 1 to control room, and secure

using screw clamps. Be sure to observe proper polarity. Include proper loop resistance (see page 2-5).

b. (Optional) Run wire from Tri-Loop Channel 2 to control room,

and secure using screw clamps. Be sure to observe proper polarity. Include proper loop resistance (see page 2-5).

c. (Optional) Run wire from Tri-Loop Channel 3 to control room,

and secure using screw clamps. Be sure to observe proper polarity. Include proper loop resistance (see page 2-5).

d. Run wire from the Model 3095MV to BURST INPUT

connections, but do not complete connections at this time. (See Figure 2-6).

NOTE

Tri-Loop commissioning will be much faster if the Tri-Loop does not have to compete with the Model 3095 MV burst commands. We therefore do not recommend completing the Burst Input connections until the Tri-Loop is commissioned (Chapter 3).

Appendix

A Model 3244MV

OVERVIEW

This appendix outlines the procedures necessary to install and commission a Model 3244MV Smart Temperature Transmitter for use with a HART Tri-Loop.

Use the HART Tri-Loop in conjunction with a Model 3244MV in operation with two sensors to acquire an independent 4–20 mA analog output signal for each sensor input. During normal operation, the 3244MV outputs four digital process variables: sensor 1, sensor 2, differential temperature, and transmitter terminal temperature. The HART Tri-Loop divides the digital signal and outputs any or all of these variables into as many as three separate 4–20 mA analog channels. You can also use the Tri-Loop with the 3244MV configured for

differential temperature measurement or Hot Backup (see Special

Considerations on page A-3).

COMMISSIONING THE TRANSMITTER

Set the Transmitter to Burst Mode

To prepare a Model 3244MV for use with a HART Tri-Loop, you must configure the transmitter to Burst Command 3, and set the order of the process variables. In burst mode, the transmitter provides digital information for the analog current in mA to the Tri- Loop. The Tri-Loop divides the signal into separate 4–20 mA loops for the primary, secondary, tertiary, and fourth variables. When using the 3244MV in conjunction with the Tri-Loop, you must also consider the configuration of the differential temperature and hot backup features, if used. To commission a Model 3244MV for use with a HART Tri-Loop, perform the following procedures.

NOTE

These procedures assume that the sensor and transmitter are connected, powered, and functioning properly, and that a Model 275 HART Communicator is connected to the transmitter control loop and is communicating successfully. For information about connecting the communicator to the transmitter, refer to the Models 3144 and 3244MV Product Manual, Rosemount publication number 00809-0100-4724.

1. From the Home screen, Select 1 Device setup, 4 Detailed setup, 3 Output condition, 2 HART output, 4 Burst option to prepare to set the transmitter to Burst Mode.

The communicator displays the Burst option screen.

2. Select Process vars/crnt.

The communicator returns to the HART output screen.

3. Select 3 Burst mode to prepare to enable Burst Mode.

The communicator displays the Burst mode screen.

4. Select On to enable burst mode.

The communicator returns to the HART output screen.

5. Select “SEND” to download the new configuration information to the transmitter.

Set Process Variable Output Order

A-2

1. From the Home screen, select 1 Device setup, 1 Process variables, 7 Variable re-map. Select “OK” to set the control loop to manual.

The communicator displays the Primary Variable screen.

2. Select the item you wish to set as the primary variable at the “Select PV” prompt.

3. Repeat step 2 for the SV, TV, and QV.

The communicator displays the Variable mapping screen.

4. Select “OK” to accept the order to which the variables are mapped, or “ABORT” to abort the entire procedure.

NOTE

Take careful note of the process variable output order. You must configure the Tri-Loop to read the variables in the same order.

5. Select “OK” to return the control loop to automatic control.

Page 33

Appendix A

Special Considerations

To initiate operation between a Model 3244MV and the Tri-Loop, you must consider the configuration of the both the Differential Temperature and the Hot Backup features, if used. For complete information regarding the Differential Temperature and Hot Backup features, refer to the Models 3144 and 3244MV Product Manual, Rosemount publication number 00809-0100-4724.

Differential Temperature Measurement

To enable the differential temperature measurement feature of a 3244MV operating in conjunction with the Tri-Loop, adjust the range end points of the corresponding channel on the Tri-Loop to include zero. For example, if you wish the secondary variable of the 3244MV to report differential temperature, configure the transmitter accordingly (see Set Process Variable Output Order on page A-2), and adjust the corresponding channel of the Tri-Loop so one range end point is negative and the other is positive.

Hot Backup

To enable the Hot Backup feature of a Model 3244MV operating in conjunction with the Tri-Loop, ensure that the output units of the sensors are the same as the units of the Tri-Loop. You may use any combination of RTDs or thermocouples as long as the units of both match the units of the Tri-Loop.

NOTE

When configured for Hot Backup, if sensor 1 (primary) fails, sensor 2 automatically becomes the primary. An alarm does not occur unless sensor 2 also fails.

INTRODUCTION

COMMUNICATING WITH A HART TRI-LOOP

This appendix provides basic communicator information on the HART Communicator Model 275 when used with a Tri-Loop. 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.

The standard configuration for a Model 275 HART Communicator is to search for devices with HART address 0. The HART Tri-Loop, which is designed to work in conjunction with other HART devices, defaults to HART address 1. Therefore, before a HART Communicator can communicate with a HART Tri-Loop, you must first change a HART Communicator setting from "always poll" to "digital poll."

1. Select "4" Utility.

2. Select "1" Configure Communication.

3. Select "1" Polling.

4. Select "Digital Poll."

When the HART Communicator is turned on, one of two menus will appear. If the HART Communicator is connected to an operating loop, the communicator will find the device and display the Online Menu (see below). If it is not connected to a loop, the communicator will indicate that no device was found. When you press OK (F4), it will display the Main menu.

The Main menu provides the following options:

• Offline–The Offline option provides access to offline configuration data and simulation functions.

• Online–The Online option checks for a device and if it finds one, brings up the Online Menu.

• Transfer–The Transfer option provides access to options for transferring data either from the HART Communicator (memory) to the transmitter (device) or vice versa. Transfer is used to move off-line data from the HART Communicator to the transmitter, or to retrieve data from a transmitter for off-line revision.

NOTE

Online communication with the transmitter automatically loads the current transmitter data to the HART Communicator. Changes in online data are made active by pressing SEND (F2). The transfer function is used only for off-line data retrieval and sending.

• Frequency Device–The Frequency Device option displays the frequency output and corresponding pressure output of currentto-pressure transmitters.

• Utility–The Utility option provides access to the contrast control for the HART Communicator LCD screen and to the autopoll setting used in multidrop applications.

Once selecting a Main menu option, the HART Communicator provides the information you need to complete the operation. If further details are required, consult the HART Communicator manual.

Online Menu

The Online Menu can be selected from the Main menu as outlined above, or it may appear automatically if the HART Communicator is connected to an active loop and can detect an operating transmitter.

NOTE

The Main menu can be accessed from the Online Menu. Press the left arrow action key to deactivate the on-line communication with the transmitter and to activate the Main menu options.

When configuration variables are reset in the on-line mode, the new settings are not activated until the information is sent to the transmitter. Press SEND (F2) when it is activated to update the process variables of the transmitter.

On-line mode is used for direct evaluation of a particular meter, reconfiguration, changing parameters, maintenance, and other functions.
