NOTICE

The THUM Adapter and all other wireless devices should be installed only after the Emerson Wireless

Gateway has been installed and is 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.

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

lift off voltage of the wired device to make sure it works properly with the THUM Adapter installed. To

determine the lift off voltage for the wired device, review the wired device operation and installation

manual.

to previously inaccessible

locations

1.3 Considerations

1.3.1 General

The THUM Adapter is connected to a HART sub-device. With simple HART configuration, the THUM

transmits the HART information from the sub-device into the Wireless network.

1.3.2 Commissioning

The THUM Adapted can be commissioned before or after installation. It may be useful to bench

commission the THUM Adapter before installation to ensure proper operation and to become familiar

with the functionality. The instruments should be installed in accordance with intrinsically safe or

non-incendive field wiring practices, when required. The THUM Adapter is powered when connected to a

powered loop.

1.3.3 Mechanical

When choosing an installation location and position for the transmitter, take into account access to the

device. For best performance, the antenna should be vertical and have some space between objects in a

parallel metal plane such as a pipe or metal framework, as the pipes or framework may adversely affect

the performance of the antenna.

1.3.4 Electrical

The THUM Adapter is connected into a powered 4–20 mA loop, powering itself by scavenging power.

The THUM Adapter causes a voltage drop across the loop. The drop is linear from 2.25 volts at 3.5 mA to

1.2 volts at 25 mA, but does not effect the 4–20 mA signal on the loop. Under fault conditions, the

maximum voltage drop is 2.5 volts.

1.3.5 Environmental

Verify that the operating environment of the transmitter is consistent with the appropriate hazardous

locations certifications.

Temperature limits

1.3.6 Wireless considerations

Power up sequence

Power should not be applied to any wireless device until the 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 Emerson

Wireless 1420 Gateway Reference Manual

.

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.

Figure 1-1. 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.

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. When installing the M20 conduit adapter into a conduit tighten to

32.5 Nm/25 ft-lb. to ensure water tight seal.

Introduction

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 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 Vdc.

Load resistor

If required, add a load resistor as shown in Figure 3-20, Figure 3-22, and Figure 3-24. 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.

When adding a load resistor, ensure that uninsulated conductors do not contact the enclosure and/or

other exposed metal parts.

1.4 Product recycling/disposal

Recycling of equipment and packaging should be taken into consideration and disposed of in accordance

with local and national legislation/regulations.

Configuration

Field Communicator

In order to communicate with the THUM Adapter, polling must be activated on the Field Communicator.

The default address for the THUM Adapter is 63. Also, note that any configuration changes must be sent

to the transmitter using the Send key (F2).

AMS Wireless Configurator

AMS Wireless Configurator is capable of connecting devices directly using a HART modem or the

Gateway. For configuring through AMS Wireless Configurator, double click the device icon and select the

Configure/Setup tab. AMS Configuration changes are implemented when the Apply button is selected.

2.5 Device network configuration

2.5.1 Join device to network

In order to communicate with the Emerson Wireless Gateway, and ultimately the Host System, the

THUM must be configured to communicate over the wireless network. This step is the wireless

equivalent of connecting wires from a transmitter to the host system.

1. From the Home screen, select 2: Configure.

2. Select 1: Guided Setup.

3. Select 1: Join Device to Network.

Using a field communicator or AMS Device Manager, 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 to those set in the Gateway, the THUM Adapter will not communicate with

the network. The Network ID and Join Key may be obtained from the Gateway on the

Setup>Network>Settings page on the web server.

2.5.2 Configure update rate

The Update Rate is the frequency at which a new measurement is taken and transmitted over the

wireless network. This by default is one minute. This may be changed at commissioning, or at any time

via AMS Wireless Configurator. The Update Rate is user selectable from eight seconds to 60 minutes.

1. From the Home screen, select 2: Configure.

2. Select 1: Guided Setup.

3. Select 2: Configure Update Rate.

2.5.3 Configure THUM Adapter long tag

The Long Tag is how the THUM Adapter will show up in the Gateway web interface. By setting this

parameter to a unique value it will be easier to determine which THUM Adapter you are communicating

with. One way to do this is to use the tag number of the wired device that the THUM adapter is

connected to followed by THUM (HARTTAG-THUM).

1. From the Home screen, select 2: Configure.

2. Select 1: Manual Setup.

3. Select 2: Device Information tab.

4. Enter the Long Tag.

2.5.4 Wired device tag

For HART 5 devices the THUM Adapter uses the message field when reporting the HART tag to the

Gateway. To ensure that you can identify the wired device in the Gateway make sure to write the tag

information into the message field for all HART 5 devices. For HART 6 or newer devices the THUM

Adapter reports the long tag as the HART tag to the Gateway.
