Explosions could result in death or serious injury:

Installation of this transmitter in an explosive environment must be in accordance with the appropriate local, national, and international standards, codes, and practices. Please review the approvals section of the 702 Reference Manual for any restrictions associated with a safe installation.

 Before connecting a Field Communicator in an explosive atmosphere, ensure the

instruments are installed in accordance with intrinsically safe or non-incendive field wiring practices

Process leaks may cause harm or result in death:

 Install and tighten process connectors before applying pressure

Electrical shock can result in death or serious injury:

 Avoid contact with the leads and terminals. High voltage that may be present on leads

can cause electrical shock

The 702 transmitter and all other wireless devices should be installed only after the Smart Wireless Gateway has been installed and is functioning properly. Wireless devices should also be powered up in order of proximity from the Smart Wireless Gateway, beginning with the closest. This will result in a simpler and faster network installation.

Shipping considerations for wireless products: The unit was shipped to you without the power module installed. Please remove the power

module prior to shipping. Each power module contains two “C” size primary lithium batteries. Primary lithium

batteries are regulated in transportation by the U. S. Department of Transportation, and are also covered by IATA (International Air Transport Association), ICAO (International Civil Aviation Organization), and ARD (European Ground Transportation of Dangerous Goods). It is the responsibility of the shipper to ensure compliance with these or any other local requirements. Please consult current regulations and requirements before shipping.

The power module with the wireless unit contains two “C” size primary lithium/thionyl chloride batteries. Each battery contains approximately 2.5 grams of lithium, for a total of 5 grams in each pack. Under normal conditions, the battery materials are self-contained and are not reactive as long as the batteries and the pack integrity are maintained. Care should be taken to prevent thermal, electrical, or mechanical damage. Contacts should be protected to prevent premature discharge.

Battery hazards remain when cells are discharged.

Power modules should be stored in a clean and dry area. For maximum battery life, storage temperature should not exceed 30 °C.

The power module has surface resistivity greater than one gigaohm and must be properly installed in the wireless device enclosure. Care must be taken during transportation to and from the point of installation to prevent electrostatic charge build-up.

Section 1: Introduction

February 2013

1.4.1 Functions of the transmitter

Switches produce either an open or closed signal. By using simple HART configuration, the 702 transmitter converts the switch signal to a wireless-enabled signal.

1.4.2 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

number 701PBKKF (part number 00753-9220-0001) into the 702 transmitter to power the device. Wireless devices should also be powered up in order of proximity from the Gateway, beginning with the closest. This will result in a simpler and faster network installation. Enable Active Advertising on the Gateway to ensure that new devices join the network faster. For more information see the Smart Wireless Gateway Manual (Document Number 00809-0200-4420).

Antenna Position

Reference Manual

00809-0200-4702, Rev CA

™

Solutions model

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 1-1. Antenna Position

Preparing (or sealing) the 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.

1.4.3 Choosing an Installation Location and Position

Introduction

Choosing an Installation Location and Position

When choosing an installation location and position, take into account access to the transmitter. For best performance, the antenna should be vertical with space between objects in a parallel metal plane, such as a pipe or metal framework, as the pipes or framework may adversely affect the antenna’s performance.

1.4.4 Electrical

Caring for the Power Module

The Rosemount 702 Wireless Discrete Transmitter is self-powered. The included Black Power Module contains two “C” size primary lithium/thionyl chloride batteries. Each battery contains approximately 2.5 grams of lithium, for a total of 5 grams in each pack. Under normal conditions, the battery materials are self-contained and are not reactive as long as the batteries and the power module are maintained. Care should be taken to prevent thermal, electrical, or mechanical damage. Contacts should be protected to prevent premature discharge.

Use caution when handling the power module, it may be damaged if dropped from heights in excess of 20 feet (6.10 m).

Making Switch Connections

Make switch connections through the cable entry in the side of the connection head. Be sure to provide adequate clearance for cover removal.

Reference Manual

00809-0200-4702, Rev CA

1.4.5 Verifying Operating Atmosphere

Verify that the operating atmosphere of the transmitter is consistent with the appropriate hazardous locations certifications.

Isolating the transmitter from sources of heat

The transmitter will operate within specifications for ambient temperatures between -40 and 185 °F (-40 and 85 °C). Heat from the process is transferred from the switch to the transmitter housing. If the expected process temperature is near or beyond specification limits, consider using an extension, or remote mount the transmitter to thermally isolate it from the process.

Figure 1-4 provides an example of the relationship between the transmitter housing

temperature rise and the extension length.

Figure 1-4. Rosemount 702 Transmitter Connection Head Temperature Rise vs. Extension Length

Introduction

Reference Manual

00809-0200-4702, Rev CA

Example

The transmitter specification limit is 185 °F (85 °C). If the ambient temperature is 131 °F (55 °C) and the maximum process temperature to be measured is 1500 °F(815 °C), the maximum permissible connection head temperature rise is the transmitter specification limit minus the ambient temperature (moves 185 °F to 131 °F [85 to 55 °C]), or 86 °F (30 °C).

In this case, an extension of 5-in. (0.13 m) meets t his requirement, but 6-in. (0.15 m) provides an additional margin of protection, thereby reducing risk of ambient thermal damage.

2.4 Configuring the Device Network

Configuring Device Network with Field Communicator

To communicate with the Gateway, and ultimately the Information System, the transmitter must be configured to communicate with the wireless network.

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 the other devices in the network. If the Network ID and Join Key are not identical, the transmitter will not communicate with the network. The Network ID and Join Key may be obtained from the Gateway on the Setup>Network>Settings page on the web server. Using a Field Communicator, the Network ID can be configured by entering the Fast Key Sequence: 2, 2, 1, 1. The Join Key can also be configured using a Field Communicator with the Fast Key Sequence: 2, 2, 1, 2.

Configuring Device Network with AMS Wireless Configurator

The final device network configuration piece is the Update Rate which, by default, is 1 minute. It can be changed at commissioning, or at any time, by using AMS Wireless Configurator or the Gateway’s web server. The Update Rate should be between 4 seconds and 60 minutes. To change the Update Rate with a Field Communicator, use the Fast Key Sequence: 2, 2, 1, 3.

3.3.2 Wiring Switches and Sensors with Liquid Hydrocarbon Detection, Measurement Option Code 61(702DX61)

Figure 3-9. Fuel Sensor Terminal

The Liquid Hydrocarbon Detection configuration is intended for use with the Tyco® TraceTek® Fast Fuel Sensor, or TraceTek sensing cable.

Figure 3-10. Fuel Sensor Connection

Connecting to the fast fuel sensor and TraceTek sensing cable

The connections to the Fast Fuel Sensor TraceTek sensing cable are made by matching the appropriately colored wires to the matching colored termination lugs.

 The Emerson Smart Wireless 702 transmitter can support up to 3 Fast Fuel sensors.

These Fast Fuel sensors are connected using TraceTek Modular Leader Cable (TT-MLC-MC-BLK), optional modular jumper cables (TT-MJC-xx-MC-BLK) and branching connectors (TT-ZBC-MC-BLK) as suggested in Figure 3-11.

 If more than one Tyco Fast Fuel sensor is attached to a 702 transmitter, the detection of

liquid hydrocarbon by one sensor is sufficient to cause the 702 transmitter to send a “Leak” message. However, it is not possible for the 702 transmitter to discern which individual sensor has detected liquid hydrocarbon.

3.5 Grounding the Transmitter

The 702 transmitter operates with the housing grounded or floating. Floating systems, however, can cause extra noise that may affect many types of readout devices. If the signal appears noisy or erratic, grounding at a single point may solve the problem. Grounding of the electronics enclosure should be done in accordance with local and national installation codes. Grounding is accomplished through the process connection using the internal or external case grounding terminal.

Determining Grounding Requirements

Each process installation has different grounding requirements. Use the options recommended by the facility for the specific switch type, or begin with Option 1, which is the most common.

Option 1:

1. Connect switch wiring shield to the grounded transmitter housing.

2. Ensure that the transmitter housing is electrically isolated from the switch wiring.

Models 702DX22 and 702DX61

February 2013

Option 2:

1. Ground switch wiring shield at the switch.

2. Ensure that the switch wiring and shield are electronically isolated from the transmitter housing.

NOTE

Always use facility recommended wiring practices.

4.2 Configuring the transmitter to communicate with the wireless network

In order to communicate with the Smart Wireless Gateway, and ultimately the Information 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 are not identical, the 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 server, shown in Figure 4-1.

Figure 4-1. Gateway Network Settings

4.3 Using AMS Wireless Configurator to configure the transmitter

Right click on the 702 transmitter and select Configure. When the menu opens, select Join Device to Network and follow the method to enter the Network ID and Join Key.

4.4 Using a field communicator to change the network ID and join key

The Network ID and Join Key may be changed in the wireless device by using the following Fast Key sequence. Set both Network ID and Join Key.

Checking for Communication Using the Smart Wireless Gateway

In the integrated web interface from the Gateway, navigate to the Explorer page. This page shows whether the device has joined the network and if it is communicating properly.

NOTE:

The time to join the new device(s) to the network is dependent upon the number of devices being joined and the number of devices in the current network. For one device joining an existing network with multiple devices, it may take up to five minutes. It may take up to 60 minutes for multiple new devices to join the existing network.

What to do if there is Immediately an Alarm Present

If the device joins the network and immediately has an alarm present, it is likely due to sensor configuration. Check the sensor wiring (see “702 Terminal Block” on page 11) and the sensor configuration (see “Fast Key Sequence” on page 15).

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

Leak detected, sensor status good

Ta bl e 5 - 1 describes use of the 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.

Important Notice

It is imperative that both PV and SV be mapped to the host system so that 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 that the device is either off of 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 that the device is not connected to the network and to take appropriate action.

 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 becomes not present on the wireless network, Appropriate action

must be taken by the host system.

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 the702 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.

7.3.3 Output Circuits, measurement option code 42 (702DX42)

The 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 702 transmitter output does not provide any voltage or current, the output circuit must have power of its own. The 702 transmitter output has maximum switch capacity per channel of 26 volts DC and 100 milliamps. A typical power supply for powering an output circuit can be 24 volts or lower.

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 CH1+ or CH2 + terminal, 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.

Note

The output functionality of the 702 transmitter requires that the network is managed by a version 4 Smart Wireless Gateway, with v4.3 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.

7.3.4 Safety shower and eye wash monitoring

Reference Manual

00809-0200-4702, Rev CA

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 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 12 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 702 transmitter senses that switch closure. This switch state is then transmitted by the 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.

Eye wash monitoring

When the eye wash valve is activated (valve open) by pushing down on the hand paddle, the TopWorx switch is activated (closed switch) and the 702 transmitter senses that switch closure. This switch state is then transmitted by the 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.

Dual Input, Opposing Contact Logic

When configured for Opposing Contact Logic, the 702 transmitter will accept the input from a single pole double throw switch on inputs CH1 and CH2, and will use opposing contact logic for the determination of the wireless outputs. The following tables describe the wireless outputs available when using opposing contact logic.

9.2.3 Momentary Discrete Inputs, measurement option code 32 and 42 (702DX32, 702DX42)

The 702 transmitter is capable of measuring momentary discrete inputs of 10 millisecond or more in duration, regardless of the wireless update rate. At each wireless update, the device reports current discrete input state and an accumulating count of close-open cycles for each input channel.

Setting variable reporting in AMS Wireless Configurator

The 702 transmitter has two choices for variable reporting: Classic - Discrete State Only, or Enhanced – Discrete State and Count. In the Classic variable reporting mode, the 702 transmitter will report variables exactly like the previous version of the device (measurement option code 22). In the Enhanced variable reporting mode, the 702 transmitter will provide both current state of the discrete channels, and a count of the discrete state change cycles. Following is a table that shows the variable mapping for both cases. Variable Reporting can be set in AMS Wireless Configurator by going to Configure > Manual Setup > HART.

Setting the reported value in AMS Wireless Configurator

The 702 transmitter reports the discrete state of switches wired to the input channels. There are various pairs of discrete states that correspond to an open or closed input switch. This pair of discrete states is called the Reported Value and can be set in AMS Wireless Configurator by going to Configure > Manual Setup > Discrete Channels > Setup Channel X (1 or 2). Under Reported Value there is a drop down menu of choices. The Reported Value can be set independently for each of the two channels.

Figure 9-7. Setting the Reported Value

Reported Value: Ta b l e 9 -2 gives the Reported Value choices and the names for each possible state. Also given are the corresponding Analog Value and Discrete Value for each possible state.

Value Name: The Name of the reported value will be seen in AMS Wireless Configurator, and on the device display. The device display may shorten the Name to fit the available display segments.

Analog Value: The Analog Value is seen on the Gateway web interface under the PV or SV. This is also the value that is reported through the Gateway to a control host that requires an analog floating point value for PV or SV.

Discrete Value: The Discrete Value is reported through the gateway to a control host that requires the true discrete state value, rather than the floating point decimal of the Analog Value.

Variable reporting, limit contact or opposing contact logic

If the Rosemount 702 transmitter has two inputs and is set for limit contact or opposing contact logic, there is a different list of reported values. Ta bl e 9 - 3 describes the values that are reported as a function of the Reported Value setting, and the four possible discrete states of True, False, Fault and Travel. Please reference Figure 9-3 on page 86 for limit contact switches and Figure 9-4

on page 87 for opposing contact switches.
