NOTICE

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.

Considerations

General

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.

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.

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.

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.

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 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

Introduction

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

25 mA

Load resistor

2.25 V

1.2 V

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.

Product recycling/disposal

Recycling of equipment and packaging should be taken into consideration and disposed of in accordance with local and national legislation/regulations.

Fast Keys 2, 2, 4, 2

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.

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.

Mounting

The Emerson ™ Wireless 775 THUM ™ Adapter can be installed in one of two configurations:



Direct mount

 Remote mount

Direct mount : The THUM Adapter is connected directly to the conduit entry of the wired device.

Figure 3-1. Direct Mount

3.2.1

Direct mount

1. Install the HART ® device according to standard installation practices, being sure to use an approved thread sealant on all connections.

2. Attach the THUM Adapter to the wired device as shown in

Figure 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 Figure 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 enough 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.

1. Install the HART device according to standard installation practices, 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 12

.

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 Figure 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 enough 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.

Loop current

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.

Wiring

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.

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.

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 eight seconds and 60 minutes. Only one update rate can be set to eight seconds.

In AMS Device Manager, select Manual Setup and then the Wireless tab.

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

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.


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.

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.

Configure HART polling

Fast Keys 2, 2, 2,4

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.

In AMS Device Manager, select Manual Setup and then the Wired Device.

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.

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.

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. 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 two and five.

In AMS Device Manager, select Manual Setup and then the Other tab.
