The THUM and all other wireless devices should be installed only after the Smart Wireless
Gateway has been installed and is functioning properly. Wireless devices should also be
powered up in order of proximity from the Smart Wireless Gateway, beginning with the
closest. This will result in a simpler and faster network installation.

During normal operation, or in fault condition, the THUM 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 installed. To determine the lift off voltage for the wired device, review the wired
device operation and installation manual.

to

The Smart Wireless 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 can be commissioned before or after installation. It may be useful to bench
commission the THUM 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.

1.3.6 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).

Reference Manual

00809-0100-4075, Rev CA

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.

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.

Section 1: Introduction

March 2014

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 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.

The THUM Adapter, attached to a powered sub-device, receives HART® communication from a
handheld Field Communicator or AMS

®

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

2.4 Connection diagrams

Bench hook-up

Connect the bench equipment as shown in either Figure 2-1 or Figure 2-2, and turn on the Field
Communicator by pressing the ON/OFF key or log into AMS. The Field Communicator or AMS
will search for a HART-compatible device and indicate when the connection is made. If the Field
Communicator or AMS fail to connect, it indicates that no device was found. If this occurs, refer
to Section 4: Commissioning.

2.5 Device network configuration

2.5.1 Join device to network

Fast Keys

In order to communicate with the Smart 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, enter the Network ID and Join Key so that they match the
Network ID and Join Key of the Smart Wireless 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 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.

2.5.2 Configure update rate

Fast Keys

Configuration

The Update Rate is the frequency at which a new measurement is taken and transmitted over
the wireless network. This by default is 1 minute. This may be changed at commissioning, or at
any time via AMS Wireless Configurator. The Update Rate is user selectable from 8 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 long tag

Reference Manual

00809-0100-4075, Rev CA

Fast Keys

The Long Tag is how the THUM Adapter will show up in the Smart Wireless 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, 2, 4, 2

2.5.4 Wired device tag

For HART 5 devices the THUM Adapter uses the message field when reporting the HART tag to
the Smart Wireless 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 reports the long tag as the HART tag to the Gateway.
