Each has a specific function as described below: ON/OFF KEY – Use to power-up the Communicator. When the Communicator is turned on, it automatically searches for a HART-compatible device on the 4-20 mA loop.

  • Page 28: Alphanumeric And Shift Keys

    UMSITRPDS3-1 Model 275 Universal Hart Communicator Important When performing certain operations, the message “OFF KEY DISABLED” indicates that the Communicator cannot be turned off. This feature helps prevent accidental shutoff of the Communicator while the output of a device is fixed or a device variable is being edited.

  • Page 29: Getting To Know The Communicator

    Model 275 Universal Hart Communicator UMSITRPDS3-1 2.4 GETTING TO KNOW THE COMMUNICATOR The HART Communicator operates either on-line or off-line. Off-line operation is used to create or edit a configuration that can then be downloaded to a HART device, such as a transmitter. On-line operation is used to download a configuration to a HART device, upload a configuration, edit HART device operating parameters, and monitor process values.

  • Page 30: Menu Structure

    For the HART Communicator to recognize a specific HART-compatible device, it must contain a description for that device. Communicator device descriptions for Moore and Siemens products are listed in Table 2-2. Device descriptions for many other HART-compatible devices from leading manufacturers are included but not listed in the table.

  • Page 52: Environmental Considerations

    Installation UMSITRPDS3-1 4.2 ENVIRONMENTAL CONSIDERATIONS Many industrial processes create severe environmental conditions. The conditions at each transmitter location must be within the specifications stated in Section 9.3 Specifications. Although the transmitter is designed to perform in harsh conditions, it is prudent to choose a location that minimizes the effects of heat, vibration, shock, and electrical interference.

  • Page 53: Electrical

    UMSITRPDS3-1 Installation • Determine if an explosion-proof or intrinsically safe installation is required. Refer to the transmitter’s rating plate for electrical classifications and to Section 4.7 and Section 9. Hazardous area information for specific approval agencies can be found in Section 9.6 and Appendix B. An intrinsically safe installation requires user-supplied intrinsic safety barriers that must be installed in accordance with barrier manufacturer’s instructions for the specific barriers used.

When measuring limits are exceeded, the overload diaphragm (5) deflects until one of the seal diaphragms (7) comes into contact with the measuring cell body (4) to protect the silicon pressure sensor (3).
