    CONSIDERATIONS General Switches produce either an open or closed signal. With simple HART configuration the Rosemount 702 converts the switch signal to a wireless-enabled signal.l. Commissioning The transmitter can be commissioned before or after installation. It may be useful to commission it on the bench, before installation, to ensure proper operation and to become familiar with its functionality.

    HART communication terminals. Connect the battery to CONFIGURATION supply power for configuration. The Rosemount 702 will receive any HART communications from a handheld Field Communicator, or AMS. When using a Field Communicator, any configuration changes must be sent to the transmitter by using the Send key (F2).
