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 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.

Smart Wireless THUM Adapter
CONSIDERATIONS
General 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.
Commissioning The THUM can be commissioned before or after installation. It may be useful
to bench commission the THUM before installation to ensure proper op eration
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.
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 m ay adve rsely
affect the performance of the antenna.
Electrical The THUM Adapter is connected into a powered 4–20 mA loop, powering
itself by scavenging power . The THUM Adapter causes a vo ltage drop across
the loop. The drop is linear from 2.25 volts at 3.5 mA to 1.2 volt s 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.
Environmental Verify that the operating environment of the transmitter is consistent with the
appropriate hazardous locations certifications.

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.

Smart Wireless THUM Adapter
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 se al.
The thread sealant also provides a lubrication to ensure easy removal of the
THUM Adapter.
Reference Manual
00809-0100-4075, Rev BA
October 2010
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 condu it tighten to 3 2.5 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.

Load Resistor
If required, add a load resistor as shown in Figure 3-20, 3-22, and 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 m etal parts.

October 2010
Direct Mount 1. Install the HART
being sure to use an approved thread sealant on all connections.
2. Attach the THUM Adapter to the wired device as shown in F igure 3-1.
When installing the THUM Adapter into the conduit entry of a wired
device, use an approved thread sealant.
3. Connect the THUM Adapter to the HART wired device using the
wiring diagrams below . See Figure 3-19 through 3-26 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 enoug h 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.
Remote Mount: The THUM Adapter is mounted separate from the wired
device housing and then connected to the wired device using conduit.

being sure to use an approved thread sealant on all connections.
2. The THUM Adapter should be mounted as shown in Figure 3-2 on
page 3-2.
3. Connect the THUM Adapter to the wired device using standard
practices. Wire running from the THUM Adapter to the wired device
must be shielded or in conduit.
4. Ground the Remote Mount Kit per local practices.
5. Connect the THUM Adapter to the HART wired device using the
wiring diagrams below . See Figure 3-19 through 3-26 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 enoug h 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.
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.

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 4-1.

STARTU P SEQ UEN CE Because the THUM is a power scavenging device, different capabilities are
available at different times after startup. Configuration is available
immediately after startup and includes Update Rate and Discovery method.
All network settings including Network ID, Join Key can not be set until the
radio is completely initialized. This may take up to three (3) minutes after
startup.
After this amount of time has passed, the THUM adapter will start to join the
network. Time to join the network depends on network size and number of
devices and if active advertising is turned on in the Gateway. After sufficient
time to join has passed go to the Explorer page on the Smart Wireless
Gateway to see if the THUM has joined.

There are two options “Variable Current Mode” and “Fixed Current Mode”.
Variable current mode is the default mode and is used when the current on
the loop is changing between 3.5 mA to 25 mA.
Fixed Current mode is user selectable. This mode is for when the current on
the loop is fixed and will not drop below 15 mA. If the current drops below 15
mA when the THUM Adapter is in fixed current mode, there may be issues
with network traffic, and the THUM Adapter may drop off of the wireless
network. The HART loop will not be affected.

device it will update for. There are 3 modes “First Device Found”, “Fixed
Polling Address”, and “Fixed Mapping”. The default mode is First Device
Found. In First Device Found Mode, the THUM Adapter will update for the first
wired device that it finds on the wired bus. This mode is best used when there
is only one device on the wired bus. If more than one wired device is found,
the THUM Adapter will go into alert.
In Fixed Polling Address mode, the THUM will only update for a wired device
at specific HART polling address. Any address can be entered. If no device is
found at this address, the THUM Adapter will go into an alarm state.
In Fixed Mapping mode, the user selects the long tag from a list of devices
that are currently on the wired bus. If the selected device goes off line, the
THUM will not start updating new device, and will go into an alarm state.
In AMS Select Manual Setup and then the Wired Device tab.
Configure HART Polling The Configure HART Polling method allows the user to select which

commands the THUM Adapter will update for the wired device. The user can
select from pre setup information or select custom and enter the HART
command that they would like to have the THUM Adapter update for the wired
device.

This mode will set the THUM Adapter up as a router only device. The THUM
Adapter will no longer look for wired devices or update for any wired device
that is on the HART loop. The THUM Adapter will continue to send updates
for itself and will also act as a wireless node in the wireless network.

secondary HART master. The THUM is set to primary as default, if another
primary master is on the HART loop it may be necessary to change the THUM
Adapter to a secondary master. This will not affect the functionality of the
THUM Adapter. The number of retries can be set to between 2 and 5.
