Wireless considerations

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 that new devices are able to join the network faster. For

more information see the Smart Wireless Gateway Manual (Document No.

00809-0200-4420).

Antenna position

The antenna should be positioned vertically, either straight up or straight down,

and should be approximately 3 ft. (1 m) from any large structure, building, or

conductive surface to allow for clear communication to other devices.

Figure 1. Antenna Position

Conduit entries

Upon installation, ensure that each conduit entry is either sealed with a conduit

plug with appropriate thread sealant, or has an installed conduit fitting or cable

gland with appropriate thread sealant. Please note that the conduit entries on the

Rosemount 702 transmitter are threaded 1/2-14 NPT.

Quick Start Guide

December 2012

The Rosemount 702 transmitter and all other wireless devices should not be set

up until after the Smart Wireless Gateway has been installed and is functioning

properly.

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, or Remote Mount, where the switch is

mounted separate from the Rosemount 702 transmitter housing, then

connected to the Rosemount 702 transmitter via conduit. Choose the installation

sequence that corresponds to the mounting configuration.

Step 1: Physical installation

Direct mount

Note

Direct mount installation should not be employed when using tubing and connectors such as

Swagelok®fittings.

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

(Figures on page 15 through page 30).

4. Connect the Black Power Module.

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.

December 2012

Quick Start Guide

The high gain, remote mount antenna kit includes coaxial sealant for the cable

connections for the lightning arrestor and antenna.

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. To install the remote antenna use one of the

following procedures:

WN option

1. Mount the antenna on a 1.5-2 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.

6. Ensure that 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.

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 Process

Management is not responsible for wireless performance or non-compliance with spectrum regulations.

Weather Proofing is Required! The remote mount antenna kit includes coaxial sealant for weather

proofing 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. Please see Figure 5 for details on how to apply coaxial sealant.

Figure 5. Applying coaxial sealant to cable connections

Step 2: 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 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 do not match that of the Gateway, the Rosemount 702

transmitter will not communicate with the network. The Network ID and Join Key
