The HARTcommunication resistance in the signal cable is always required for alow impedance power supply. It is absolutely necessary to install itbetween voltage supply and the <strong>VEGADIS</strong> <strong>62</strong>.Note:If the instrument is powered via a VEGAMET signal conditioninginstrument, then the communication resistor is already included in thesignal conditioning instrument. A communication resistor in the signalcable must not be installed.Overview=~1234Fig. 9: <strong>VEGADIS</strong> <strong>62</strong> in conjunction with an individual sensor1 Sensor2 <strong>VEGADIS</strong> <strong>62</strong>3 HART resistor > 150 Ω (with low impedance power supply necessary)4 Voltage supply/Processing16 <strong>VEGADIS</strong> <strong>62</strong>36469-EN-100514
