Configuration overview


You can configure the CSI 9420 either prior to installation or after the device is installed at the measurement location. You do not need to physically install or connect to the transmitter to complete the configuration. The transmitter, however, reports an alert until the sensor is connected; this is the expected behavior.
Note: The specific user interface for performing the configuration varies depending on the host used.


  1. Connect to a wired HART interface.
    Skip this step if your CSI 9420 is purchased pre-configured from the factory.
  2. Set the wireless network credentials (Network ID and Join Key) using wired connection.
    Perform this step for the device to join a wireless network. After the device has joined, you can complete the rest of the steps over a wireless link.
  3. (Optional) Name the device (Tag and Device Description).
    By default, the tag is VT xxxx, where xxxx is the unique radio ID on the wireless network. The device joins the network and operates correctly even if no changes are made, but it is usually preferable to name the device something meaningful for the specific application.
  4. Specify the type of sensor installed (for example: 1 accelerometer, 1 accelerometer with temperature, or 2 accelerometers) and name the sensor.
    The factory default configuration is one accelerometer named SENSOR 1. Complete this step for different configurations and name the sensor something meaningful for the specific application.
  5. Enter the sensor sensitivity.
    For improved accuracy, replace the nominal sensitivity value of 25 mV per g (2.55 mV per m/s2) (default) with the value corresponding to your specific sensor.
  6. Specify the units (English, metric, or SI) that will be used for each parameter.
    By default, units are set to English, unless the device is shipped to Japan.
  7. Specify which measurements (velocity, temperature, etc.) correspond to the process variables PV, SV, TV, and QV.
    By default, PV is the Overall Velocity on sensor 1, SV is the PeakVue measurement on sensor 1, TV is the sensor 1 bias voltage, and QV is the supply voltage.
  8. Specify alert levels.
    Determine the thresholds at which measurement alerts will display and determine the behavior of device alerts.
  9. Specify how the parameters will be published (optimized mode or generic mode).
    By default, the device is configured to use generic mode as it provides the most consistent overall performance.
  10. Specify how often the parameters are published (update rate).
    The default update rate is once every 60 minutes. A faster update rate is not recommended, unless the device is powered by an external power source, as it significantly reduces the power module life.
  11. Optimize for power consumption.
    Reduce the publish rate and set the LCD mode to Off to minimize power consumption. As an additional step, you can configure the PowerSave mode settings to extend the power module life.
  12. Configure trending of parameters.
    You can trend parameters in multiple locations such as in a plant historian, in AMS Machinery Manager, and in a DCS control system.
  13. If the device configuration will not be managed by a HART DCS (such as DeltaV), specify whether AMS Machinery Manager can make configuration changes.
    By default, the device is set for a DCS to manage the configuration, and changes from AMS Machinery Manager are not permitted. You can, however, allow AMS Machinery Manager to make configuration changes by enabling MHM Access Control from AMS Device Manager or from a Field Communicator.
  14. If the device is licensed for the Advanced Diagnostics application (spectral data retrieval), configure storage of energy bands, spectra, and waveforms in the AMS Machinery Manager database.
    With the Advanced Diagnostics application, you can collect data on-demand, automatically at periodic intervals, or on alert. Store on Alert is the recommended operating mode.
