    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.
  • Page 4 Conduit Entry 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; please order model number 701PBKKF or part number 00753-9220-0001. Figure 3. Connection Diagram...

    Quick Start Guide December 2012 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. 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, or Remote Mount, where the switch is...
  • Page 6 1. Install the switch according to standard installation practices making sure 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.
  • Page 7 The antenna should be approximately 3-ft. (0.91 m) from any large structures or buildings, to allow clear communication to other devices. 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.
  • Page 8 December 2012 Quick Start Guide When installing remote mount antennas for the Rosemount 702 transmitter, always use established safety procedures to avoid falling or contact with high-power electrical lines. Install remote antenna components for the Rosemount 702 transmitter in compliance with local and national electrical codes and use best practices for lightning protection.

  • Page 14: Reference Information: Wiring Switch Inputs, Output Circuits, And Leak

    Reference information: wiring switch inputs, output circuits, and leak sensors Dry contact switch inputs The Rosemount 702 Transmitter has a pair of screw terminals for each of two channels, and a pair of communication terminals. These terminals are labeled as follows:...
  • Page 15 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.

  • Page 17 December 2012 Dual input, limit contact logic 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.
  • Page 18 Quick Start Guide Dual input, opposing contact logic When configured for Opposing Contact Logic, the Rosemount 702 transmitter will accept the input from a double pole single throw switch on inputs CH1 and CH2, and will use opposing contact logic for the determination of the wireless outputs.
  • Page 19 December 2012 Momentary discrete inputs, measurement option code 32 and 42 The Rosemount 702 transmitter is capable of detecting momentary discrete inputs of 10 milliseconds or more in duration, regardless of the wireless update rate. At each wireless update, the device reports current discrete input state along with an accumulating count of close-open cycles for each input channel.
  • Page 20 Count 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.
  • Page 21 Quick Start Guide December 2012 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.
