  • Page 11: Dry Contact Switch Inputs

    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 12 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 13 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 14 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.
  • Page 15 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.
  • Page 16 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.

LOAD Plunger arrival detection Terminal block connections The plunger arrival detection configuration for measurement option code 52 is intended for use with the ETC Cyclops Plunger Arrival Sensor.
  • Page 18 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. By default, the Plunger state (channel 1) is enabled to latch high state changes for a period of one minute.

  • Page 19: System Verification

    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.
  • Page 20 The Rosemount 702 Wireless Discrete Transmitter can support up to 500 feet of TraceTek hydrocarbon or solvent sensor cable (TT5000 or TT5001 series). The total amount of sensor cable connected to a single Rosemount 702 Transmitter is not to exceed 500 ft.
  • Page 21 ■ 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 23: Safety Shower And Eye Wash Monitoring

    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.

  • Page 24: Product Certifications

    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.
