1 Wireless considerations

1.1 Power up sequence

The power module should not be installed on any wireless device until the
Emerson 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
Wireless Gateway Reference Manual.

1.2 THUM Adapter position

THUM Adapter should be positioned vertically straight up, and 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. The THUM Adapter should not be mounted vertically straight
down. See Wireless THUM Adapter Reference Manual for more information.

Figure 1-1: THUM Adapter Position

1.3 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 lubrication to ensure easy removal of the
THUM Adapter.

1.4

Quick Start Guide 5

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 watertight seal.

Quick Start Guide September 2020

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.

1.5 Power supply

• Minimum loop load of 250 Ohms.

• The THUM Adapter communicates via 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

1.6 Load resistor

If required, add a load resistor as shown in Figure 8 on page 10, Figure 12 on
page 13, and Figure 16 on page 15. The resistor should be adequately rated
for the application (1 W minimum) and be compatible with the supplied
splice connector which accepts wire sizes from 14 to 22 AWG.

Loop

To ensure proper operation, the THUM Adapter should not be installed on a
HART loop with other active HART masters. HART masters that are active
periodically, such as a field communicator can be used on a loop with a
THUM Adapter.

7 Device network configuration

In order to communicate with the Emerson Wireless Gateway, and
ultimately the Information System, the transmitter must be configured to
communicate with 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 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,
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, shown in Figure 7-1.
