    1) When using a foreign dual resolver multi-turn transducer, note how the signals are paired in the AMCI CML cable and use this pairing when generating your wiring diagrams. 2) The cable shields must be isolated from earth ground at the transducer to prevent ground loops and ground shifts.

  • Page 41: Avoiding Ground Loops And Ground Shifts

     If the shields of the transducer cable are isolated from the body of the transducer, which is the AMCI standard practice, connect the shields of the transducer cable to the shields of the extension cable and ground the shields at the NX2A4E2.

  • Page 48 EtherNet/IP is not a multi-master protocol. There can be only one bus master on the network at a time. In order to program the NX2A4E2, the AMCI Net Configurator utility must act as a bus master.
