September 2014Momentary discrete inputs, measurementoption code 32 and 42The Rosemount 702 Wireless Discrete Transmitter is capable ofdetecting momentary discrete inputs of 10 millisecond or morein duration, regardless of the wireless update rate. At eachwireless update, the device reports current discrete state alongwith an accumulating count of close-open cycles for each inputchannel.Figure 5.

Variable MappingVariable reporting Variable mappingEnhanced –Discrete State withCountPVSVTVQVCH1StateCH2StateCH1 CountCH2CountDiscrete output circuits, measurement optioncode 42The Rosemount 702 Wireless Discrete Transmitter has twochannels that can each be configured for discrete input oroutput. Inputs must be dry contact switch inputs and these weredescribed in a preceding section of this document. Outputs area simple switch closure to activate an output circuit. TheRosemount 702 output does not provide any voltage or current,the output circuit must have power of its own. The Rosemount702 output has maximum switch capacity per channel of 26volts DC and 100 milliamps. A typical power supply for poweringan output circuit can be 24 volts or lower.Figure 6. Reporting of Current Discrete State andCount in AMS Device ManagerNoteIt is very important that the polarity of the output circuitis as shown in the wiring diagrams, with the positive ( )side of the circuit wired to the CH1 or the CH2 terminal, and the negative (-) side of the circuit wired tothe CMN terminal. If the output circuit is wiredbackwards, it will remain active (switch closed) regardlessof the state of the output channel.Discrete output switch functionalityVariable reporting and mappingThe Rosemount 702 transmitter will report variables exactly likethe previous version of the device (measurement option code22). In the Enhanced variable reporting mode, the Rosemount702 transmitter will provide both current state of the discretechannels, and a count of the discrete state change cycles.Following is a table that shows the variable mapping for bothcases. Variable Reporting can be set in AMS Device Manager bygoing to Configure Manual Setup HART .www.rosemount.comThe discrete output of the Rosemount 702 Transmitter is drivenby the host control system, through the Smart WirelessGateway, and out to the Rosemount 702 Transmitter. The timerequired for this wireless communication from the Gateway tothe Rosemount 702 Transmitter is dependent on many factors,including the size and topology of the network and the totalamount of downstream traffic on the wireless network. For anetwork that is constructed to our best practices, typical delaysin communication of a discrete output from the Gateway to theRosemount 702 Transmitter are 15 seconds or less. Rememberthat this delay is only part of the latency that well be observed ina control loop.9

Rosemount 702 Wireless Discrete TransmitterNoteThe output switch functionality of the Rosemount 702transmitter requires that the network is managed by aversion 3 Smart Wireless Gateway with v3.9.7 firmware,or a version 4 Gateway with v4.3 or higher firmwareinstalled.Figure 7. Output Circuit WiringFigure 8. Possible Configurations for Both Channel 1and Channel 2September 2014If two output circuits are connected to a single Rosemount 702Transmitter with a single power supply, both CH and CMNterminals must be connected to each output circuit. Thenegative power supply wires must be at the same voltage andconnected to both CMN terminals.Figure 10. Dual Output Circuits with One PowerSupplySwitching greater currents or voltagesIt is important to note that the maximum output switchingcapacity is 26 volts DC and 100 milliamps. If a greater voltage orcurrent is to be switched, an interposing relay circuit can beused. Figure 11 shows an example of a circuit to switch highercurrents or voltages.Figure 11. Wiring an Interposing Relay to SwitchGreater Currents or VoltagesSpecial considerations for dual output circuitsIf both channels are connected to output circuits, it is veryimportant that the CMN terminal of each circuit be at the samevoltage. Employing a common ground for both output circuits isone way to ensure that both circuits have CMN terminals at thesame voltage.Figure 9. Dual Output Circuits with a Common Ground10www.rosemount.com

Rosemount 702 Wireless Discrete TransmitterSeptember 2014Safety Shower and Eye Wash MonitoringThe Rosemount 702 Transmitter can be used to monitor safetyshowers and eye wash stations by using switch kits provided byTopWorx , an Emerson company. These kits are ordered as apart of the Rosemount 702 model code and are available forboth insulated and un-insulated pipes. These kits contain theswitches, brackets and cables that are necessary to install theRosemount 702 to monitor both the safety shower and the eyewash in a single station. Because each has two input channels,one Rosemount 702 Transmitter can be used to monitor both asafety shower and an eye wash.Safety shower monitoringWhen the shower valve is activated (valve open) by pullingdown on the handle, the TopWorx switch is activated (closedswitch) and the 702 Transmitter senses that switch closure. Thisswitch state is then transmitted by the 702 Transmitter to theGateway, which then sends that information to the control hostor alert system. When the shower valve is closed, the switchremains in the activated state until it is reset by a technician. Theswitch can be re-set only by placing a ferrous metal object onthe far side of the sensing area of the switch.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 washFigure 16. TopWorx Switch Installed on Safety ShowerUL and CSA switchesSafety shower and eye wash monitoring kits are available witheither UL or CSA switches. This designation refers to the ordinarylocation certification of the GO Switch in the kit. These are nothazardous locations certificates. The Go Switch is regarded as asimple apparatus and does not require its own hazardouslocations certificate. Either GO Switch is suitable for installationin hazardous locations when wired to the Rosemount 702Transmitter with an appropriate hazardous locations certificate.The CSA GO Switch is for applications in Canada, the UL GOSwitch is for applications in all other world areas.Installation drawings and instructionsInstallation drawings and instructions for safety shower and eyewash kits are included in the Rosemount 702 TransmitterReference Manual, Appendix D (document 00809-0200-4702,Rev CA).
