4. 0 Installing the HART For a GF868 flowmeter the option card connector is mounted on the Option Card cont card and the HART device leads should go to pins 1 and 2 of this connector As for other option cards installed in the same meter as the HART option card the HART device will not recognize any option card installed in Slots 3 5 and it will only recognize option cards installed in Slots 1 2 if they are Analog Input Analog Output or RTD option cards For XGM868 XGS868 and XMT868 flowmeters the HART device connections must be made to pins 1 and 2 of 12 pin terminal block J2 on the terminal board Therefore you must make sure that any option card installed in Slot 1 does not use these terminals Note Refer to your User s Manual for a complete description of the available Slot 1 option cards and their terminal usage Flowmeter Software Panametrics flowmeters that are shipped with a factory installed Setup HART option card require no special setup procedures by the user The meter automatically configures itself for HART communication on startup However for field installation of a HART option card the card must be configured in the factory test menu before it will be recognized by the meter Thereafter the initialization will be automatic on startup Consult Panametrics for specific instructions In addition to setting up the HART option card so that it is recognized by the meter the analog output of the option card may be c
