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.

data

) capabilities extend the full benefits of Plantweb™ to previously inaccessible

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.

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.

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.

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.

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.

2.5 Device network configuration

2.5.1 Join device to network

Fast Keys

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

Fast Keys

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.

Fast Keys

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, 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
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.

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.

Loop current THUM Adapter voltage drop

3.5 mA 2.25 V

25 mA 1.2 V

3.2.4 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.

3.2.5 Wiring

Installation

Note

In order for the THUM Adapter to function properly there must be at least 250 Ohms resistance in the
loop. If the 4–20 mA loop does not have the required resistance, wire a resistor as shown in Figure 3-20,

Figure 3-22, or Figure 3-24 as applicable.

When adding a load resistor ensure that uninsulated conductors do not contact the enclosure and/or
other exposed metal parts.

4.2.2 Verify operation

Operation can be verified in three locations: by using the Field Communicator, at the Gateway via the
Gateway’s integrated web server, or via AMS Wireless Configurator.

Field Communicator

In order for the THUM Adapter to communicate with a Field Communicator, a THUM Adapter DD is
required. The Field Communicator must be put into a polling mode using the THUM adapter address of

63. Connect the Field Communicator to the wired device. The Field Communicator should find both the

THUM Adapter and the wired device.

Gateway

If the THUM Adapter was configured with the Network ID and Join Key, and sufficient time has passed for
network polling, the transmitter will be connected to the network. To verify device operation and
connection to the network with the Gateway’s integrated web server, open the Gateway’s integral web
interface and navigate to the Explorer page.

Note

It may take several minutes for the device to join the network.

5.2 Startup sequence

Because the Emerson™ Wireless 775 THUM™ Adapter 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 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 Emerson Wireless
Gateway to see if the THUM Adapter has joined.

5.3.2 4-20 mA current

Fast Keys

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.

5.3.3 Voltage drop

Fast Keys

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 Device Manager, select Manual Setup and then the Wired Device tab.

5.3.4 Discovery mode

Fast Keys

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.

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.
