IMPORTANT NOTICE

This installation guide provides basic guidelines for the Smart Wireless THUM Adapter. It does not provide instructions for detailed configuration, diagnostics, maintenance, service, troubleshooting, or installations. Refer to the THUM Adapter Reference Manual

(document number 00809-0100-4075) for more instruction. The manual and this QIG are also available electronically on www.rosemount.com.

WARNING

Explosions could result in death or serious injury:

Installation of this transmitter in an explosive environment must be in accordance with the appropriate local, national, and international standards, codes, and practices. Please review the Product Certifications section for any restrictions associated with a safe installation.

• Before connecting a 375 Field Communicator in an explosive atmosphere, ensure the instruments are installed in accordance with intrinsically safe or non-incendive field wiring practices.

Electrical shock can result in death or serious injury:

• Avoid contact with the leads and terminals. High voltage that may be present on leads can cause electrical shock.

This device complies with Part 15 of the FCC Rules. Operation is subject to the following conditions. This device may not cause harmful interference. This device must accept any interference received, including interference that may cause undesired operation.

This device must be installed to ensure a minimum antenna separation distance of

7.87-in. (20 cm) from all persons.

IMPORTANT NOTICE

During normal operation, or in fault condition, the THUM Adapter will cause a 2.5 V drop in the connected loop. It is important to ensure that the power supply can provide at least

2.5 V more than the minimum operating voltage of the wired device to make sure it works properly with the THUM Adapter installed. To determine the minimum operating voltage for the wired device, review the wired device operation and installation manual.

ONSIDERATIONS

Power Up Sequence

Power should not be applied to any wireless device until the Smart Wireless Gateway

(“Gateway”) is installed and functioning properly. Wireless devices should also be powered up in order of proximity from the Gateway, beginning with the closest. This will result in a simpler and faster network installation. Enable Active Advertising on the Gateway to ensure that new devices join the network faster. For more information see the Smart Wireless

Gateway Manual (Doc. No. 00809-0200-4420).

THUM Adapter Position

If possible, the THUM Adapter should be positioned vertically, either straight up or straight down, and it should be approximately 3 ft. (1 m) from any large structure, building, or conductive surface to allow for clear communication to other devices. If the THUM Adapter is mounted horizontally wireless communication range may be decreased. See THUM

Adapter reference manual (00809-0100-4075) for more information.

Figure 1. THUM Adapter Position

Conduit Entry

When installing the THUM Adapter into the conduit entry of a wired device, use an approved thread sealant. Thread sealant provides a water tight seal. The thread sealant also provides a lubrication to ensure easy removal of the THUM Adapter.

375 Field Communicator Connections

In order for the 375 Field Communicator to interface with the THUM Adapter, the wired device must be powered. The 375 must be put into poll mode and should use the THUM

Adapter address of 63.

Power Supply

Minimum loop load of 250 Ohms.

The THUM Adapter communicates and derives power from a standard 4-20 mA/HART loop.

The THUM Adapter causes a small voltage drop on the loop which is linear from 2.25 V at

3.5 mA to 1.2 V at 25 mA. Under fault conditions, the maximum voltage drop is 2.5 V. The

THUM Adapter will not affect the 4-20 mA signal under normal or fault conditions as long as the loop has at least a 2.5 V margin at the maximum loop current (25 mA for a typical 4-20 mA/HART device).

Load Resistor

If required, add a load resistor as shown in Figure 5, 7, and 9. The resistor should be

adequately rated for the application (1W minimum) and be compatible with the supplied splice connector which accepts wire sizes from 14 to 22 AWG.

NSTALLATION

The THUM Adapter can be installed in one of two configurations:

Direct Mount: The THUM Adapter is connected directly to the conduit entry of the wired device.

Figure 2. Direct Mount

Remote Mount: The THUM Adapter is mounted separate from the wired device housing and then connected to the wired device using conduit or other suitable means.

Figure 3. Remote Mount

Direct Mount

1. Install the HART

® device according to standard installation practices and the manufacturer’s instructions, being sure to use an approved thread sealant on all connections.

2. Attach the THUM Adapter to the wired device as shown in Figure 2.

3. Connect the THUM Adapter to the HART wired device using the wiring diagrams below.

See Figures 4, 5, 6, and 7 on the following pages.

4. Close the housing cover on the HART wired device, so that metal touches metal, but do not over tighten to prevent damaging the unit.

NOTE

Two splice connectors are included with the THUM Adapter. The first is a two connection splice. The second is a three connection splice for use with a resistor, if there is not enough resistance in the loop. Both of these splice connectors can accept 14 to 22 gauge wire. See wired device reference manual for information on the required loop resistance.

1. Install the HART device according to standard installation practices and the manufacturer’s instructions, being sure to use an approved thread sealant on all connections.

2. The THUM Adapter should be mounted as shown in Figure 3 on page 5.

3. Connect the THUM Adapter to the wired device using standard practices. Wire running from the THUM Adapter to the wired device should be shielded or in conduit when installed in electrically noisy environments.

4. Connect the THUM Adapter to the HART wired device using the wiring diagrams below.

See Figure 4, 5, 6, and 7 on the following pages.

5. Close the housing cover on the HART wired device, so that metal touches metal, but do not over tighten to prevent damaging the unit.

Device Network Configuration

In order to communicate with the Smart Wireless Gateway, and ultimately the Information

System, the transmitter must be configured to communicate with the wireless network. This step is the wireless equivalent of connecting wires from a transmitter to the information system. Using a Field Communicator or AMS, enter the Network ID and Join Key so that they match the Network ID and Join Key of the gateway and other devices in the network. If the Network ID and Join Key are not identical, the THUM Adapter will not communicate with the network. The Network ID and Join Key may be obtained from the Smart Wireless

Gateway on the Setup>Network>Settings page on the web server, shown in Figure 11.

Right click on the THUM Adapter and select Configure. When the menu opens, select Join

Loop Current Test

To verify that the THUM Adapter will work under all conditions, a loop current test should be performed. This test will exercise the loop under the highest possible voltage drop conditions.

1. Place loop in manual control.

2. Drive loop to high alarm level. For details see wired device instruction manual.

• When the THUM Adapter is connected to a valve, this will need to be done at the current source and not from the valve.

• When the THUM Adapter is connected to a transmitter, this will need to be performed at the transmitter.

3. Place the THUM Adapter into fixed voltage drop mode.

AMS

Right click on the THUM Adapter and select Configure. When the menu opens, select

Manual Setup from the window on the left and select the Wired Device tab on the top.

Make sure that the Time drop down menu at the bottom of the page has Current selected. Under the Voltage Drop drop down menu in the Smart Power Options box,

select Fixed Voltage Drop. Hit the Apply button to make any changes. See Figure 12 on page 12.
