Product description

The Roseount 702 for plunger arrival detection is designe dto work with the ETC Cyclops plunger

arrival sensor (ET-11000). The transmitter provides power to the plunger arrival sensor, reads and

communication the sensor state via wirelessHART. Features of the Rosemount 702 Transmitter

include:

•Simple and easy installations proctices currently being used for robust installations

•Flexibility to meet your most demanding applications

•Sensor state latching for host system compatibility

•Provides poiwer to external plunger arrival sensor

•The integral LCD display conveniently displays the latched plunger sensor state,

power output state, and diagnostics of the transmitter

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.

Antenna PositionFigure 1-1:

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.

Conduit EntryFigure 1-2:

1.4 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.

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.

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.

2.1 Direct mount

Note

Direct mount installation should not be employed when using tubing and

connectors such as Swagelok® fittings.

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.

Procedure

1. Install the switch according to standard installation practices making sure

to use thread sealant on all connections.

2. Run wiring (and conduit if necessary) from the switch to the Rosemount

702 Transmitter.

3. Pull the wiring through the threaded conduit entry of the Rosemount 702

Transmitter.

4. Attach the switch wiring to the terminals as indicated on the wiring

diagram (see Chapter 5).

5. Connect the black power module.

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.
