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.

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.

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.

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.
