  • Page 19: 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 20 6.2.2 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 21 6.2.3 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 22 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 24 Count 6.3.2 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 rising or falling state changes, dependent on the input signal. The latch period (hold time) can be configured anywhere between 0 seconds and 10 minutes in 1 second increments.
  • Page 25 Latched rising 1 minute The reported state will report the latched value once the Rosemount 702 recognizes that the input signal has transitioned. As soon as the reported state is no longer latched, the device is prepared for the next event.
  • Page 26 The latch only applies to transitions into the active state. If the input signal goes inactive and active again before the initial latch hold timer expires, the latch hold timer will restart from the beginning of the most recent event.

    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 41 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.

  • Page 42: Product Certification

    All wireless devices require certification to ensure that they adhere to regulations regarding the use of the RF spectrum. Nearly every country requires this type of product certification. Emerson is working with governmental agencies around the world to supply fully compliant products and remove the risk of violating country directives or laws governing wireless device usage.
