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.

data

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.

1.3.6 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).

Reference Manual

00809-0100-4075, Rev CA

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.

Introduction

Reference Manual

00809-0100-4075, Rev CA

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.

Section 1: Introduction

March 2014

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.

The THUM Adapter, attached to a powered sub-device, receives HART® communication from a handheld Field Communicator or AMS

Field communicator

In order to communicate with the THUM Adapter, polling must be activated on the Field Communicator. The default address for the THUM Adapter is 63. Also, note that any configuration changes must be sent to the transmitter using the Send key (F2).

AMS wireless configurator

AMS is capable of connecting devices directly using a HART modem or the Gateway. For configuring through AMS Wireless Configurator, double click the device icon and choose the Configure/Setup tab. AMS configuration changes are implemented when the Apply button is selected.

2.4 Connection diagrams

Bench hook-up

Connect the bench equipment as shown in either Figure 2-1 or Figure 2-2, and turn on the Field Communicator by pressing the ON/OFF key or log into AMS. The Field Communicator or AMS will search for a HART-compatible device and indicate when the connection is made. If the Field Communicator or AMS fail to connect, it indicates that no device was found. If this occurs, refer to Section 4: Commissioning.

2.5 Device network configuration

2.5.1 Join device to network

Fast Keys

In order to communicate with the Smart 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, enter the Network ID and Join Key so that they match the Network ID and Join Key of the Smart Wireless 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 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.

2.5.2 Configure update rate

Fast Keys

2, 1, 1

2, 1, 2

The Update Rate is the frequency at which a new measurement is taken and transmitted over the wireless network. This by default is 1 minute. This may be changed at commissioning, or at any time via AMS Wireless Configurator. The Update Rate is user selectable from 8 seconds to 60 minutes.

1. From the Home screen, select 2: Configure.

2. Select 1: Guided Setup.

3. Select 2: Configure Update Rate.

2.5.3 Configure THUM long tag

Reference Manual

00809-0100-4075, Rev CA

Fast Keys

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).

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 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.

3.2.5 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.

5.1 Safety messages

Instructions and procedures in this section may require special precautions to ensure the safety of the personnel performing the operations. Information that potentially raises safety issues is

indicated by a warning symbol ( ). Please refer to the following safety messages before performing an operation preceded by this symbol.

5.1.1 Warnings

March 2014

Failure to follow these installation guidelines could result in death or serious injury:

 Only qualified personnel should perform the installation

Explosions could result in death or serious injury.

 Before connecting a Field Communicator in an explosive atmosphere, make sure that

the instruments are installed in accordance with intrinsically safe or non-incendive field wiring practices

 Verify that the operating atmosphere of the transmitter is consistent with the

appropriate hazardous locations certifications

Electrical shock could cause death or serious injury.

 Use extreme caution when making contact with the leads and terminals

This device must be installed to ensure a minimum antenna separation distance of 20 cm from all persons.

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.

5.3 Advanced setup

5.3.1 Configure advanced update rate

Reference Manual

00809-0100-4075, Rev CA

Fast Keys

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.

2, 2, 1,3

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. The HART loop will not be affected.

In AMS Select Manual Setup and then the Wired Device tab.

2, 2, 2,1

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 Select Manual Setup and then the Wired Device tab.

2, 2, 2,2

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.

2, 2, 2,3

Operation and Maintenance

Reference Manual

00809-0100-4075, Rev CA

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.

5.3.5 Configure HART polling

Section 5: Operation and Maintenance

March 2014

Fast Keys

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 Select Manual Setup and then the Wired Device.

2, 2, 2,4

5.3.6 Configure router only mode

Fast Keys

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.

2, 2, 5,2

5.3.7 HART address

Fast Keys

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.

2, 2, 5,3

In AMS Select Manual Setup and then the Other tab.

5.3.8 HART master

Fast Keys

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 2 and 5.

In AMS Select Manual Setup and then the Other tab.
