  • Page 20: Reference Information: Wiring Switch Inputs, Output Circuits, And Leak Sensors

    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 21 5.2.2 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 22 5.2.3 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 23 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.

OUTPUT 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.
  • Page 28 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.
  • Page 29 April 2018 Quick Start Guide Switching 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.
  • Page 30 Cyclops Plunger Arrival Sensor Manual. 5.8.2 Latching 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.
  • Page 31 April 2018 Quick Start Guide Short events (less than latch hold time) of the measured value will be latched to the reported value for the duration of latch hold time. Figure 5-14: Latch Time Short Events A. Measured B. Reported The start of the ltach hold timer begins when the measured signal first transitions to active state.
  • Page 32 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.

  • Page 35 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.
  • Page 36 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.

    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.
  • Page 40 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.
