3Device 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 3‐1.

channels, and a pair of communication terminals. These terminals are labeled
as follows:
CH1+:Channel one positive
CMN:Common
CH2+:Channel two positive
CMN:Common

5.2Wireless output specifications
5.2.1Dual 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.
When configured for Limit Contact Logic, the Rosemount 702 Transmitter
will accept the input from two single pole single throw switch on inputs CH1
and CH2, and will use limit contact logic for the determination of the wireless
outputs.

5.3.1Setting variable reporting
The Rosemount 702 Transmitter has two choices for variable reporting:
Classic - Discrete State Only, or Enhanced – Discrete State and Count.
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.
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.
Quick Start Guide25
Page 26
Quick Start Guide
5.5Discrete 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.
Page 28
Quick Start Guide
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.

5.7Switching 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 5‐11 shows an example of a
circuit to switch higher currents or voltages.

5.8.2Latching 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.

5.8.3Latching 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.
5.8.4System Verification
April 2018
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.

• 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.

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.

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.
Mapping the PV, SV, and PV_HEALTHY variables and parameter
Below is a the Gateway screen where the PV, SV, and PV_HEALTHY variables

6Safety 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.

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
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.
