  • Page 14: Choosing An Installation Location And Position

    1.3.3 Choosing an installation location and position When choosing an installation location and position, take into account access to the Rosemount 702 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.

  • Page 15: Electrical

    Electrical Caring for the power module The Rosemount 702 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.

    Introduction Reference Manual 00809-0200-4702, Rev DA July 2017 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).

  • Page 91 FALSE (0.0) 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 switches on inputs CH1 and CH2, and will use limit contact logic for the determination of the wireless outputs.

  • Page 92: Momentary Discrete Inputs, Measurement Option Code 32 And 42

    Momentary discrete inputs, measurement option code 32 and 42 (702DX32, 702DX42) The Rosemount 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.
  • Page 93 Figure 9-6. Reporting of Current Discrete State and Count in AMS Wireless Configurator Setting variable reporting in AMS Wireless Configurator The Rosemount 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 transmitter will report variables exactly like the previous version of the device (measurement option code 22).
  • Page 94 Setting the reported value in AMS Wireless Configurator The Rosemount 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 >...

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. Table 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.

  • Page 96: Discrete Output Circuits

    Discrete output switch functionality The discrete output of the Rosemount 702 Transmitter is driven by the host control system, through the Emerson Wireless Gateway, and out to the transmitter. The time required for this wireless communication from the gateway to the 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.
  • Page 97 Connecting two output circuits with a single power supply 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.
  • Page 98 Setting the reported value Though the output switch state is driven by command from the control host, the Rosemount 702 Transmitter then reports back the state of the output switch via the PV and SV. There are various pairs of discrete states that correspond to an open or closed output switch.
