Smart Wireless THUM Adapter

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.

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 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.

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.

WIRELESS CONSIDERATIONS

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 lubrication to ensure easy removal of the THUM Adapter.

M20 Conduit Adapter

When using the M20 Conduit Adapter on the THUM Adapter, use an approved thread sealant and tighten wrench tight to the THUM Adapter.

Field Communicator Connections

In order for the Field Communicator to interface with the THUM Adapter, the wired device must be powered. The Field Communicator 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 via 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).

Limit the power supply to 0.5 Amps maximum, and voltage to 55 Volts DC.

Loop Current THUM Adapter voltage drop

3.5 mA 2.25 V 25 mA 1.2 V

Load Resistor

If required, add a load resistor as shown in Figure 8, 12, and 16. 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.

BENCH TOP CONFIGURATION

When performing bench top configuration it is suggested that you connect the THUM Adapter to a wired device. If this is not possible the following wiring diagrams can be used. For bench top configuration ensure that the power supply that you are using is limited to 0.5 Amps maximum.

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 4.

3. Connect the THUM Adapter to the HART wired device using the wiring diagrams below. See Figures 21, 8, 10, and 12 on the following pages.

4. Close the housing cover on the HART wired device, so that metal touches metal, but do

NOTE

not over tighten to prevent damaging the unit.

accept 14 to 22 gauge wire. See wired device reference manual for information on the required loop resistance.

Remote 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 5. Remote 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. The THUM Adapter should be mounted as shown in Figure 5 on page 6.

3. Ground the Remote Mount Kit per local practices.

4. 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.

5. Connect the THUM Adapter to the HART wired device using the wiring diagrams below. See Figure 21, 8, 10, and 12 on the following pages.

6. 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 co nnectors can accept 14 to 22 gauge wire. See wired device reference manual for information on the required loop resistance.
