Chapter 6—Motor Protection116 Power Xpert C445 Global Motor Management Relay MN042003EN—January 2019 www.eaton.comApplication ConfigurationBasic ParametersApplication dependent parameters need to be configured sothat the monitoring and protection functions can beimplemented.The C445UM Monitoring User Interface and Power XpertinControl software tool both walk users through an easySetup Wizard for these parameters.Table 24. Basic ParametersNotes1 These values may change depending on MM selection.2 These values may change depending on MM use.Advanced ParametersApplication dependent parameters are required for someadvanced applications. Users must set PT or CT Ratios ifexternal CTs or PTs are used. Additionally, users who wantto utilize motor torque and efficiency monitoring should setMotor Rated Speed and Motor Rated Stator Resistance forhigher accuracy.Table 25.
