NOTE: For the 900 MHz CSI 9420, the fast key sequences assume that DD Dev v1, DD v9 is being used. For the 2.4 GHz CSI 9420, the fast key sequences assume that DD Dev v2, DD v2 is being used. This is true for all fast key sequences. Table 2-3.
Reference Manual MHM-97408, Rev. 2 June 2008 CSI 9420 Figure 2-5. Sensor Sensitivity For improved accuracy, the nominal value of 25mV/g should be replaced with the value corresponding to your specific sensor. ALARM LEVELS Fast Keys 1, 1, 5 The CSI 9420 sets HART status bits to indicate when measured values exceed the configured thresholds. Each measured value has three (3) levels: Advisory, Maintenance, and Failed that may be set independently.
Reference Manual MHM-97408, Rev. 2 June 2008 CSI 9420 If all else fails, one “rule of thumb” for vibration is to examine the current level at which the equipment is operating. Then, assuming the equipment is in good working order, set the Advisory level at 2x the current value (or at a minimum of 0.05 in/sec. RMS, whichever is greater), set the Maintenance level at 4x the current value, and set the Failed level at 8x the current value. For example, if the current value for Overall Velocity is 0.1 in/sec.

Reference Manual MHM-97408, Rev. 2 June 2008 CSI 9420 There are, however, a number of different methods for measuring and reporting Overall Velocity, so it is important to ensure that the measurement conditions are similar when trying to duplicate the value reported by the CSI 9420 with that of a handheld. The CSI 9420 uses ISO 10816, which defines a measurement bandwidth of 2 Hz to 1 kHz. The ISO 10816 general fault levels at various turning speeds are depicted graphically in the figure below.
Reference Manual MHM-97408, Rev. 2 June 2008 PEAKVUE CSI 9420 PeakVue is a patented technique that is extremely 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.
Reference Manual CSI 9420 MHM-97408, Rev. 2 June 2008 Again, keep in mind that these are generic limits.They are provided as a starting point and these values (for a 3600 RPM machine) are used as the default alert thresholds by the vibration transmitter. 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.
Reference Manual MHM-97408, Rev. 2 June 2008 TEMPERATURE CSI 9420 The levels at which to set temperature alerts depend on a variety of factors including the specific process, the operating environment, and the characteristics of the equipment being monitored. This discussion provides some generic guidelines, given some knowledge of the variables involved, for setting the thresholds for your specific CSI 9420 installation.
Reference Manual MHM-97408, Rev. 2 June 2008 CSI 9420 In general, the best way to detect a developing fault related to temperature is to look for an increase in the temperature, relative to ambient, over time. This implies that, for reliable alerting, the thresholds should change as ambient temperature changes. In practice, this can be difficult to do because it requires the operator constantly to monitor the ambient temperature and adjust the alert levels accordingly.
Reference Manual MHM-97408, Rev. 2 June 2008 CSI 9420 Use the following relationships to determine Trise. • Trise = 65 °C + serv_fact_temp; for class A insulation • Trise = 85 °C + serv_fact_temp; for class B insulation • Trise = 110 °C + serv_fact_temp; for class F insulation • Trise = 130 °C + serv_fact_temp; for class H insulation • Trise = 150 °C + serv_fact_temp; for class N insulation serv_fact_temp = • 5 for service factor of 1.
