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 approvals section of the THUM reference manual 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.
Process leaks may cause harm or result in death.
• Install and tighten process connectors before applying pressure.
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.
NOTICE
NOTICE
NOTICE
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 Gateway, beginning with the
closest. This will result in a simpler and faster network installation.

Considerations
General The Smart Wireless THUM Adapter is connected to a HART sub-device. With simple HART configu-
ration, the THUM transmits the HART information from the sub-device unto the WirelessHART net-
work.
The THUM can be commissioned before or after installation. It may be
useful to commission it on the bench, before installation, to ensure proper
operation and to become familiar with its functionality. When applicable, make
sure the instruments are installed in accordance with intrinsically safe or
non-incendive field wiring practices. The device will be powered whenever THUM is
connected to a powered loop.
Location
When choosing an installation location and position, take into account the
need for access to the transmitter. For best performance, the antenna should
be vertical with 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.
THUM Power Options
The THUM has two power options; variable current, and fixed current mode.
Variable Current
Variable current mode is the mode that the THUM should be in if the current on the 4-20 mA loop can
change between 4 to 20 mA. The THUM will drop 2.25 volts at 2.5 mA and 1 volt at 25 mA. The
voltage drop is linear between these two points. The THUM will operate
according to standard specifications under this mode.
Fixed Current
Fixed current mode can only be used when the current of the loop will never fall below 20 mA. The
THUM will always drop 1 volt across the loop. If the current of the loop falls below 20 mA the
THUM, and the rest of the wireless network may not function properly.

Connections The THUM is compatible with a number of sub-devices. See section 3 for details on wiring the
THUM to different types of sub-devices.
The THUM will receive any HART communication from a handheld Field Communicator, or AMS®.
In order for the THUM to receive HART communication the sub-device must be powered. When us-
ing a Field communicator polling must be turned on, the default HART address for the THUM is ad-
dress 15. When using a Field Communicator, any configuration changes must be sent to the transmit-
ter using the Send key (F2). AMS configuration changes are implemented when the Apply button is
clicked.
AMS® Wireless Configurator
AMS is capable of connecting to devices directly, using a HART modem, or with the Gateway. When
configuring on the bench with a HART modem, double click the device icon, then choose the Config-
ure/Setup tab (or right click and select Configure/Setup). Configure the device settings using the Direct
Connection menu. When configuring with the Gateway, double click the device icon then choose the
Configure/Setup tab (or right click and select Configure/Setup). Configure the device settings using the
Wireless Connection menu. To check or change sensor configuration using a 375 Field Communicator,
enter the following Fast Key Sequence: 2, 1, 3.
To communicate with the Gateway, and ultimately the Information System, the transmitter must be
configured to communicate with the wireless network. Using a Field Communicator or AMS, enter the
Network ID and Join Key so they match the Network ID and Join Key of the Gateway and the other
devices in the network. If the Network ID and Join Key are not identical, the transmitter will not com-
municate 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. Using a 375 Field Communicator, the Network ID
can be configured by entering the Fast Key Sequence: 2, 2, 1, 1. The Join Key can also be configured
using a 375 Field Communicator with the Fast Key Sequence: 2, 2, 1, 2.
The final device network configuration piece is the Update Rate. There are three update rates for the
THUM. Each Update Rate can be configured independently of the other two. One of the Updates is
for THUM specific information such as THUM temperature and communication status. The other two
Update Rates are for sub-device information. The information that is sent for the sub-device and the
frequency that it is sent can all be changed at commissioning or at any other time. At default the Up-
date Rate for all three Updates is 1 minute. The Updates can be changed using AMS or a 375 Field
Communicator.

Mounting The THUM can be installed in one of two configurations: Direct Mount, where the THUM is
connected directly to the conduit entry of the sub-device, or Remote Mount, where the THUM is
mounted separate from the sub-device housing, then connected to the sub-device via conduit. Choose
the installation sequence that corresponds to the mounting configuration.
1. Install the HART® device according to standard installation practices, being sure to use
thread sealant on all connections.
2. Using the threaded conduit entry attach the THUM to the HART® device making sure to
position the THUM in a vertical position, using a 90-degree elbow, if necessary.
3. Connect the THUM to the HART® sub-device using the wiring diagrams below. See
Figures 1, 2, 3, and 4 on the following pages.
4. Close the housing cover on the HART® device, so that metal touches metal, and tighten
to safety specifications. Please note that the unit may be damaged by over tightening the
cover.
NOTE
The THUM includes two euro splice connectors. The first is a two compartment splice. The second is a
three compartment splice which contains a 250 Ohm resistor, to be used if there is not 250 Ohms of
resistance in the loop.
1. Install the HART® device according to standard installation practices, being sure to use
thread sealant on all connections.
2. Mount the THUM in a location for good wireless network communication. Make sure to mount the
THUM in a vertical position.
3. Using standard practices connect the THUM wires to the sub-device.
4. Wire the THUM to the HART® sub-device using the wiring diagrams below. See
Figures 1, 2, 3, and 4 on the following pages.
