1 Wireless considerations

1.1 Power up sequence

The Smart Wireless Gateway should be installed and functioning properly before any wireless field devices are powered. Install the Black Power Module, SmartPower™ Solutions model number 701PBKKF (part number 00753-9220-0001) into the Rosemount 702 Transmitter to power the device. Wireless devices should be powered up in order of proximity from the Gateway, beginning with the closest device, then working outward from the Gateway. This results in a simpler and faster network installation. Enable Active Advertising on the Gateway to ensure new devices are able to join the network faster. For more information see the Emerson™ Wireless 1420 Gateway Reference Manual.
1.2

Antenna position

The antenna 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.

1.3 Conduit entry
Upon installation, ensure each conduit entry is either sealed with a conduit plug using approved thread sealant, or has an installed conduit fitting or cable gland with appropriate threaded sealant. Note the conduit entries on the Rosemount 702 Transmitter are threaded ½–14 NPT.

Field Communicator connections

The power module needs to be installed before the Field Communicator can interface with the Rosemount 702 Transmitter. This transmitter uses the Black Power Module; Order model number 701PBKKF or part number 00753-9220-0001.

2 Physical installation

The Rosemount 702 Transmitter can be installed in one of two configurations:
• Direct mount, where the switch is connected directly to the Rosemount
702 Transmitter housing’s conduit entry.
• Remote mount, where the switch is mounted separate from the
Rosemount 702 Transmitter housing, then connected to the Rosemount 702 Transmitter via conduit.
Select the installation sequence that corresponds to the mounting configuration.
Quick Start Guide
2.1

Direct mount

Note
Direct mount installation should not be employed when using tubing and connectors such as Swagelok® fittings.
Direct MountFigure 2-1:

Quick Start Guide 7
Quick Start Guide
Procedure
1. Install the switch according to standard installation practices making sure to use thread sealant on all connections.
2. Attach the Rosemount 702 Transmitter housing to the switch using the threaded conduit entry.
3. Attach the switch wiring to the terminals as indicated on the wiring diagram (see Chapter 5).
4. Connect the Black Power Module.
Note
Wireless devices should be powered up in order of proximity from the Smart Wireless Gateway, beginning with the closest device to the Gateway. This will result in a simpler and faster network installation.

5. Close the housing cover and tighten to safety specification. Always ensure a proper seal so the metal touches metal, but do not over tighten.
6. Position antenna vertically, either straight up or straight down. The antenna should be approximately 3 ft. (0.91 m) from any large structures or buildings, to allow clear communication to other devices.

2.3 High gain, remote antenna (optional)

The high gain, remote antenna options provide flexibility for mounting the Rosemount 702 Transmitter based on wireless connectivity, lightning protection, and current work practices.

Quick Start Guide
Figure 2-3:
Rosemount 702 Transmitter with High Gain, Remote Antenna

2.3.1 Install the high gain, remote antenna (WN option)

Prerequisites
Find a location where the remote antenna has optimal wireless performance. Ideally this will be 15–25 ft. (4.6–7.6 m) above the ground or 6 ft. (2 m) above obstructions or major infrastructure.
Quick Start Guide 11
Quick Start Guide
WARNING!
When installing remote mount antennas for the Rosemount 702 Transmitter, always use established safety procedures to avoid falling or contact with high-power electrical lines.
Install remote antenna components for the Rosemount 702 Transmitter in compliance with local and national electrical codes and use best practices for lightning protection.
Before installing, consult with the local area electrical inspector, electrical officer, and work area supervisor.
The Rosemount 702 Transmitter remote antenna option is specifically engineered to provide installation flexibility while optimizing wireless performance and local spectrum approvals. To maintain wireless performance and avoid non-compliance with spectrum regulations, do not change the length of cable or the antenna type.
If the supplied remote mount antenna kit is not installed per these instructions, Emerson is not responsible for wireless performance or non­compliance with spectrum regulations.
Procedure
April 2018
1. Mount the antenna on a 1.5 to 2-in. pipe mast using the supplied mounting equipment.
2. Connect the lightning arrestor directly to the top of the Rosemount 702 Transmitter.
3. Install the grounding lug, lock washer, and nut on top of lightning arrestor.
4. Connect the antenna to the lightning arrestor using the supplied LMR-400 coaxial cable ensuring the drip loop is not closer than 1 ft. (0.3 m) from the lightning arrestor.
5. Use the coaxial sealant to seal each connection between the wireless field device, lightning arrestor, cable, and antenna.
Note
The remote mount antenna kit includes coaxial sealant for weatherproofing the cable connections for the lightning arrestor, antenna, and Rosemount 702 Transmitter. Coaxial sealant must be applied to guarantee performance of the wireless field network. See
Figure 2‐4 for details on how to apply coaxial sealant.

Quick Start Guide
Applying Coaxial Sealant to Cable ConnectionsFigure 2-4:
6. Ensure the mounting mast and lightning arrestor are grounded according to local/national electrical code.
Any spare lengths of coaxial cable should be placed in 12-in. (0.3 m) coils.

3 Device network configuration

In order to communicate with the Smart Wireless Gateway, and ultimately the host 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 Wireless Configurator, enter the Network ID and Join Key so they match the Network ID and Join Key of the Gateway and other devices in the network. If the Network ID and Join Key do not match that of the Gateway, the Rosemount 702 Transmitter 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 interface, shown in
Figure 3‐1.
Gateway Network SettingsFigure 3-1:

3.1 AMS Wireless Configurator

1. Right click on the Rosemount 702 Transmitter.
2. Select Configure.
3. When the menu opens, select Join Device to Network.
4. Follow the method to enter the Network ID and Join Key.

4 Verify operation

There are four ways to verify operation: using the optional local display (LCD), using the Field Communicator, using the Smart Wireless Gateway’s integrated web interface, or by using AMS Suite Wireless Configurator. If the Rosemount 702 Transmitter was configured with the Network ID and Join Key, and sufficient time has passed, the transmitter will be connected to the network.

4.1 Local display

4.1.1 Start-up sequence

When the Rosemount 702 Transmitter is first powered up, the LCD display will display a sequence of screens: All Segments On, Device Identification, Device Tag, and then the user chosen variables of the periodic display.
During steady state operation, the LCD display gives a periodic display of user chosen variables at the configured wireless update rate. These variables can be selected from a list of six:
• Channel 1 State
• Channel 1 Count
• Channel 2 State
• Channel 2 Count
• Electronics Temperature
• Supply Voltage
Refer to the Rosemount 702 Reference Manual for error codes and other LCD display messages. The chevron-shaped status bar at the top of the screen indicates the progress of the network join process. When the status bar is filled, the device is successfully connected to the wireless network.

4.3 Smart Wireless Gateway

In the Gateway’s integrated web server, navigate to the Explorer page. This page shows whether the device has joined the network and is communicating properly.
Note
It may take several minutes for the device to join the network.
Note
If the device joins the network and immediately has an alarm present, it is likely caused by the sensor configuration. Check the sensor wiring (see
Figure 5‐1) and the sensor configuration (see Table 5‐6).
