  • Page 22: Publishing Mode

    2.1.7 Publishing mode The CSI 9420 can publish in either of two modes: optimized or generic (default). Optimized mode uses less power by combining a large amount of information into a single command. In this mode, only the four standard process variables (PV, SV, TV, and QV) are published at the specified update interval and cached in the Smart Wireless Gateway.

  • Page 23: Minimize Power Consumption

    3-12. PowerSave mode PowerSave mode is available in CSI 9420 devices that are Rev. 3 or later and it enables the device to make measurements less frequently, thereby conserving power. This is ideal when either power module life is more critical than the acquisition rate or when changes in vibration are only expected to occur over extended periods of time.

  • Page 24: Trend Parameters

    60 minutes (54 minutes may be optimal for older versions of the CSI 9420). When this value is set to 1X, the CSI 9420 acquires a new reading at the update rate. A PowerSave Skip Multiplier of 2X combined with a 60-minute update rate results in a new acquisition every 120 minutes (every two hours).

    The CSI 9420 uses (lower-frequency) Overall Velocity in conjunction with (higher- frequency) PeakVue to provide a holistic solution across all frequencies while optimizing the usage of the limited power and bandwidth available in a wireless device. The majority of developing fault conditions manifest in one or both of these key parameters.

  • Page 100: Peakvue

    1.0 in/s PeakVue ™ PeakVue is a patented Emerson technology that is very useful for isolating high- frequency phenomena associated with developing faults, especially in rolling-element bearings. The premise for PeakVue is that the high-frequency components are not readily detected with more conventional measurements such as Overall Velocity, low-frequency energy (LFE), or digital overall.
  • Page 101 For frequent automated monitoring, such as that offered by the CSI 9420, the levels can be increased for most balance of plant equipment running between 900 and 4000 RPM. You can use the "rule of tens" as a simple but effective approach to monitoring PeakVue on most rolling element bearing machines.
  • Page 102 The appropriate alerts for a given machine will be a function of its design, service, and turning speed. Utilizing the embedded PeakVue technology, the CSI 9420 identified developing problems at a couple of test sites during early field trials. In both cases, the problem was not visible with conventional low-frequency analysis.
  • Page 103 Velocity, PeakVue, and temperature The defective bearing was removed and Figure 5-7 shows the developing problem that was the source of the impacting. After replacing the bearing, the PeakVue vibration is significantly reduced, as shown in Figure 5-8, indicating that the problem has been resolved.

  • Page 104: Temperature

    This section provides some generic guidelines, given some knowledge of the variables involved, for setting the thresholds for your specific CSI 9420 installation. However, the generic methodologies described here are no substitute for first-hand knowledge of your plant.

    The input bandwidth of the measurement is approximately 20 kHz. This waveform is then digitized and analyzed within the CSI 9420 to produce the desired vibration parameters. Due to the high-frequency nature of the measurement, it is inherently susceptible to electromagnetic interference (EMI) and radio frequency interference (RFI), which can cause distortions in the measurement.

  • Page 109: Mitigate Interference

    Accelerometer EMI and RFI considerations Mitigate interference The following are four basic things you can do to reduce EMI and RFI on measurements: • Use a shorter cable, if possible. For more details, see Section 6.1.1. Note The leads on the sensor cables, as delivered, are specially prepared for ease of installation. Before attempting to cut the cables, be aware that cutting cables is associated with significant additional rework to correctly prepare the sensor for installation.
  • Page 110 Accelerometer EMI and RFI considerations Figure 6-2 shows how to run the accelerometer through a conduit that is grounded on both ends. As a general rule, the transmitter housing itself is grounded through the base where it is mounted. Since the conduit is electrically connected to the transmitter housing, this effectively grounds the conduit at the transmitter end.

  • Page 111: Install Ferrites

    Accelerometer EMI and RFI considerations 6.1.3 Install ferrites Note The accelerometers are shipped with ferrites installed at the accelerometer end. To maintain the optimum performance of the accelerometer, do not remove the ferrites. To meet the stated performance criteria, the standard accelerometer cable has two (2) ferrites installed.
  • Page 112 The performance of the accelerometer is not maintained beyond a 3-m (10-ft) cable-length unless you install additional ferrites. All low-power sensors for use with the CSI 9420 are shipped with additional ferrites if their cable lengths exceed 3 meters. To ensure compliance with the CE directive, if the cable...
  • Page 113 Accelerometer EMI and RFI considerations From a compliance perspective, you do not need to install the ferrites if the cable is in a ferromagnetic conduit (such as galvanized steel) because this type of conduit provides additional shielding. Note that the conduit entry of the device is ½ inch NPT. If you install ferrites with a conduit, you will need a wider conduit ( ¾...

  • Page 116 Accelerometer EMI and RFI considerations Figure 6-8: Ferrites installed on an armor-jacketed cable You need an additional ferrite for devices that use external DC supply. This ferrite is included with the transmitter if you order the external power option. Figure 6-9: Transmitter using an external power option with ferrites installed This is a snap-on ferrite.
  • Page 117 Accelerometer EMI and RFI considerations The ferrite in this example is Fair-Rite P/N 0431164281, which has a reactance that ranges from 28 Ω at 1 MHz to 310 Ω at 100 MHz and 240 Ω at 250 MHz. It supports a maximum cable diameter of 0.260 inch (6.6 mm).

  • Page 118: Reduce Polarized Interference

    Accelerometer EMI and RFI considerations Figure 6-10 also shows that ferrites provide a huge amount of RFI suppression and are needed to maintain measurement integrity in the presence of strong electromagnetic interference. Do not remove the ferrites installed on the accelerometer cables that are shipped from the factory, even if you mitigate interference using other methods.
