Wireless considerations

Power up sequence

The 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.

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.

Figure 2: Antenna Position

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 transmitter. This transmitter uses
the Black Power Module; Order model number 701PBKKF or part number 00753-9220-0001.

Figure 4: Connection Diagram

The transmitter and all other wireless devices should not be set up until after the Wireless Gateway has been installed and is
functioning properly.

Physical installation

The Rosemount 701 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.

Direct mount

Note

Direct mount installation should not be employed when using tubing and connectors such as Swagelok® fittings.

High gain, remote antenna (optional)

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

Figure 7: Rosemount 702 Transmitter with High Gain, Remote Antenna

Install the high gain, remote antenna (WN option)

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.

WARNING
When installing remote mount antennas for the transmitter, always use established safety procedures to avoid falling or
contact with high-power electrical lines.

Install remote antenna components for the 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 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 non-compliance with spectrum regulations.

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 701 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 8 on page 7 for details on how to apply coaxial sealant.

6 Rosemount 702 Wireless Discrete Transmitter

August 2018

Figure 8: Applying Coaxial Sealant to Cable Connections

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.

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 9 on page

7.

Wireless output specifications

Dual input

The Rosemount 702 Transmitter will accept the input from one or two single pole single throw switches on inputs CH1 and CH2.
The wireless output of the transmitter will be both a primary variable (PV) and a secondary variable (SV). The PV is determined by
the CH1 input. The SV is determined by the CH2 input. A closed switch drives a TRUE output. An Open switch drives a FALSE output.

Note

Any dry contact input may optionally be inverted by the device, so change the discrete logic state. This is useful, for instance, if a
normally open switch is used to replace a normally closed switch.

Discrete output circuits, measurement option code 42

The Rosemount 702 Transmitter has two channels that can each be configured for discrete input or output. Inputs must be dry
contact switch inputs and these were described in a preceding section of this document. Outputs are a simple switch closure to
activate an output circuit. The Rosemount 702 Transmitter output does not provide any voltage or current, the output circuit must
have power of its own. The Rosemount 702 Transmitter output has maximum switch capacity per channel of 26 volts DC and 100
milliamps.

14 Rosemount 702 Wireless Discrete Transmitter

August 2018

Note

It is very important that the polarity of the output circuit is as shown in the wiring diagrams, with the positive (+) side of the circuit
wired to the + terminal of each channel, and the negative (-) side of the circuit wired to the CMN terminal. If the output circuit is
wired backwards it will remain active (switch closed) regardless of the state of the output channel.

Discrete output switch functionality

The discrete output of the Rosemount 702 Transmitter is driven by the host control system, through the Smart Wireless Gateway,
and out to the Rosemount 702 Transmitter. The time required for this wireless communication from the Gateway to the
Rosemount 702 Transmitter is dependent on many factors, including the size and topology of the network and the total amount of
downstream traffic on the wireless network. For a network that is constructed to our best practices, typical delays in
communication of a discrete output from the Gateway to the Rosemount 702 Transmitter are 15 seconds or less. Remember that
this delay is only part of the latency that well be observed in a control loop.

Note

The output switch functionality of the Rosemount 702 Transmitter requires that the network is managed by a version 4 Smart
Wireless Gateway, with v4.3 or greater firmware installed.

Special considerations for dual output circuits

If both channels are connected to output circuits, it is very important that the CMN terminal of each circuit be at the same voltage.
Employing a common ground for both output circuits is one way to ensure that both circuits have CMN terminals at the same
voltage.

Figure 21: Dual Output Circuits with a Common Ground

A. LOAD
B. OUTPUT

If two output circuits are connected to a single Rosemount 702 Transmitter with a single power supply, both CH + and CMN
terminals must be connected to each output circuit. The negative power supply wires must be at the same voltage and connected
to both CMN terminals.

Figure 22: Dual Output Circuits with One Power Supply

A. LOAD
B. OUTPUT

Switching greater currents or voltages

It is important to note that the maximum output switching capacity is 26 volts DC and 100 milliamps. If a greater voltage or current
is to be switched, an interposing relay circuit can be used. Figure 23 on page 17 shows an example of a circuit to switch higher
currents or voltages.

Latching feature

The Rosemount 702 has a latching feature that, when enabled, allows detection of momentary state changes to be held for a
configurable latch period. The latching feature can be configured to detect either high or low state changes. By default, the Plunger
state (channel 1) is enabled to latch high state changes for a period of one minute.

The following are some examples to demonstrate how the latching time works.

Note

Hold time is set to four seconds for illustration in the following examples.

Short events (less than latch hold time) of the measured value will be latched to the reported value for the duration of latch hold
time.

Figure 26: Latch Time Short Events

A. Measured
B. Reported

The start of the latch hold timer begins when the measured signal first transitions to active state.

Figure 27: Latch Hold Time Start

A. Measured
B. Reported

The latch only applies to transitions into the active state. As soon as the reported value is no longer latched,the devices is armed for
the next event.

Figure 28: Latch Applies to Transitions to Active State

A. Measured
B. Reported

If the measured value goes inactive and active again before the initial latch hold timer experies, the latch hold timer will restart
from the beginning of the most recent event.

Latching warnings

WARNING
When state latching is enabled, the discrete variable reported to the system will represent the latched value which may not
be the actual state value measured by the Rosemount 702 Transmitter

WARNING
Ensure that the state latch time value is long enough for the value to be reported throughout the entire system to
guarantee the state transition is not missed. After configuring discrete latching function, check for proper operation at the
system level to ensure the desired state transitions are captured as desired.

System Verification

After installation of the 702DX52 for plunger arrival one must verify functionality.

■

Verify the sensor: To do so, pass a ferrous object (ex. Wrench) past the cyclops sensor to simulate an arrival. Verify via the LCD
screen and/or field communicator that channel 1 indicates a state change. If a state change is seen, sensor wiring is correct; if
nothing is seen, please go back through the installation steps and confirm that everything has been done accordingly.

■

Verify System integration: It is important to verify the latch time is configured correctly. The default latch period is set to one
minute. Verify the host system can detect the arrival event by moving a ferrous metal object (ex. Wrench) past the arrival
sensor. The signal should be passed from the device, through the Wireless Gateway and detected at the final host application
(ex. PLC, Modbus/OPC, etc.). If nothing is seen, confirm the latch time is appropriate considering the full system scan cycle.

Important notes regarding the use of Tyco TraceTek Fast Fuel Sensor and TraceTek sensing cable:

■

Tyco TraceTek sensors must be installed as per manufacturer recommendations.

■

Do not run the Rosemount 702 Transmitter for long periods (more than two weeks) with a Tyco fuel sensor in the leak state as
this will more rapidly deplete the power module.

Liquid hydrocarbon detection interface, for Modbus® mapping

Table 5 on page 21 describes use of the Rosemount 702 Transmitter for hydrocarbon detection in other communications

protocols such as Modbus or OPC. It is imperative that both PV and SV be mapped to the host system so as to make a good
interpretation of the condition and status of the leak detector.

Table 5: Liquid Hydrocarbon Detection Interface, for Modbus Mapping

PV SV Description/interpretation

1.0 1.0 Normal condition, no leak detected,
sensor status good

0.0 1.0 or 0.0 Leak detected, sensor status good

1.0 0.0 Sensor Not Connected, Assume Leak,
take appropriate action

NOTICE

It is imperative that both PV and SV be mapped to the host system so the diagnostic information on the sensor status is captured.

In addition, system considerations must be observed to ensure that the device is still connected to the wireless network and
reporting values. On an Emerson Smart Wireless Gateway, this can be done by referring to the parameter: PV_HEALTHY.
PV_HEALTHY has a “True” state when the device is on the network and its updates are current, not late or stale, and the device is
functioning properly. A “False” state of PV_HEALTHY means the device is either off the network, the data updates are not current,
or that there is a malfunction of the device (such as an electronics failure). In the case of a “False” state of PV_HEALTHY, it is
recommended to assume the device is not connected to the network and take appropriate action.

Quick Start Guide 21

August 2018

Mapping the PV, SV, and PV_HEALTHY variables and parameter

Below is a the Gateway screen where the PV, SV, and PV_HEALTHY variables and parameter can be mapped.

Figure 34: Smart Wireless Gateway Modbus Register Map

The Fast Fuel Sensor Diagnostics will propagate via the SV variable. This additional information will provide additional sensor Status
information while using the TraceTek Fast Fuel Sensor.

WARNING

If a device is not present on the wireless network, appropriate action must be taken by the host system.

Safety shower and eye wash monitoring

The Rosemount 702 Transmitter can be used to monitor safety showers and eye wash stations by using switch kits provided by
TopWorx™, an Emerson company. These kits are ordered as a part of the Rosemount 702 model code, or separately as an accessory
kit, and are available for both insulated and un-insulated pipes. These kits contain the switches, brackets and cables that are
necessary to install the Rosemount 702 to monitor both the safety shower and the eye wash in a single station. Because each has
two input channels, one Rosemount 702 Transmitter can be used to monitor both a safety shower and an eye wash.

Each Safety Shower Monitoring kit contains:

■

Two TopWorx GO™ Switch magnetic proximity switches

■

Two cables, one six foot and one twelve foot

■

Two black polymer cable glands

■

Mounting kit for safety shower and eye wash

Safety shower monitoring

When the shower valve is activated (valve open) by pulling down on the handle, the TopWorx switch is activated (closed switch)
and the Rosemount 702 Transmitter senses that switch closure. This switch state is then transmitted by the Rosemount 702
Transmitter to the Gateway, which then sends that information to the control host or alert system. When the shower valve is
closed, the switch remains in the activated state until it is reset by a technician. The switch can be re-set only by placing a ferrous
metal object on the far side of the sensing area of the switch.

switch) and the Rosemount 702 Transmitter senses that switch closure. This switch state is then transmitted by the Rosemount
702 Transmitter to the Gateway, which then sends that information to the control host or alert system. When the eye wash valve is
closed, the switch remains in the activated state until it is reset by a technician. The switch can be re-set only by placing a ferrous
metal object on the far side of the sensing area of the switch.
