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.
NOTICE
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.

1.3
Considerations
1.3.1
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.
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.

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.
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
4
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.

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 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).

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.

3.2.3
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.

5.2
Startup sequence
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.

Configure advanced update rate
Fast Keys
2, 2, 1,3
The “Configure Update Rate” method sets all three update rates based on one user input. The
“configure Advanced Update Rate” method allows for each update rate to be set independently
of the other two. Values for all update rates are between 8 seconds and 60 minutes. Only one
update rate can be set to 8 seconds.
In AMS Select Manual Setup and then the Wireless tab.
5.3.2
4-20 mA current
Fast Keys
2, 2, 2,1
This optimizes the THUM Adapter to the available loop current.
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.
In AMS Select Manual Setup and then the Wired Device tab.
5.3.3
Voltage drop
Fast Keys
2, 2, 2,2
This optimizes the THUM Adapter to the available voltage on the loop. There are two options:
Variable and Fixed. Variable is the default mode. In Variable mode the THUM drops between
2.25 V at 3.5 mA and 1.2 V at 25 mA. In Fixed mode the THUM will always drop 2.25 volts. Fixed
mode is used for verifying that there is enough voltage on the loop in the loop check procedure.
In AMS Select Manual Setup and then the Wired Device tab.
5.3.4
Discovery mode
Fast Keys
2, 2, 2,3
The discovery mode is how the THUM Adapter determines which wired 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.

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.
5.3.5
Configure HART polling
Fast Keys
2, 2, 2,4
The Configure HART Polling method allows the user to select which commands the THUM

select custom and enter the HART command that they would like to have the THUM Adapter
update for the wired device.
In AMS Select Manual Setup and then the Wired Device.
5.3.6
Configure router only mode
Fast Keys
2, 2, 5,2
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.
In AMS Select Manual Setup and then the Other tab.
5.3.7
HART address
Fast Keys
2, 2, 5,3
This is the HART Polling address of the THUM adapter. This can be changed from 0 to 63. This is
used when using wired HART communication to talk with the THUM. The THUM Adapter default
HART polling address is 63.
In AMS Select Manual Setup and then the Other tab.
5.3.8
HART master
Fast Keys
2, 2, 5,4
Here is where the user can set the THUM Adapter to either a primary or secondary HART master.
