5.1 Connecting SITRANS LUT400 Note The SITRANS LUT400 supports several different transducers. Some, like the XPS-30, are driven by a low power level, while others, like the XPS-15, are driven by a high power level. It may be possible to damage a lower power transducer like the XPS-30 if the transducer selection is currently set to one of the high power transducers.

Page 279: Determine The Noise Source
If the measured noise is above 5 dB go to Non-Transducer Noise Sources below. 1. Connect only the shield wire of the transducer to the SITRANS LUT400. If the measured noise is below 5 dB, continue with the next step. If the noise is above 5 dB, go to Common Wiring Problems below.
Page 280: Common Wiring Problems
● Connections between the wire supplied with the transducer, and any customer installed extension wire should only be grounded at the LUT400. On Siemens transducers the white wire is negative and the black wire is positive. If the extension wire is colored differently, make sure that it is wired consistently.
