Chapter 3 Setting Up Measurements This chapter describes setting up the measurement definitions in Emonitor to use with the Enpac Ex. Measurement definitions define how to collect and store measurements. You can create several different types of measurement definitions at each location. Emonitor can then take advantage of the abilities of your data collector by combining some of the measurement definitions when you load them into the data collector.
32 Setting Up Measurements Measurement Definition Options These topics describe the available selections for setting up measurement definitions in Emonitor. You determine these selections by selecting Tools > Set Active Collectors in Emonitor. Figure 3.1 Set active collectors The names of the active data collectors appear in inverse text IMPORTANT If no data collectors are active, the selections that appear in the Measurement Definition pane are the ones available to ALL data collectors.
Setting Up Measurements 33 • Time Waveform - Time domain measurement of time vs. amplitude, usually for displacement, velocity, or acceleration. Remember that the available measurement types in Emonitor depend on the active collectors you select with the Tools > Set Active Collectors. If you have two or more active data collectors, you may not see all the selections available for the Enpac Ex. Measurement Filters Emonitor and Enpac Ex each support certain measurement filters.
34 Setting Up Measurements Filters in Emonitor are referred to as software filters. Filters in data collectors are referred to as hardware filters. Hardware filters alter the signal in the Enpac Ex. Emonitor software filters alter the signal (data representing the signal) after you unload the data into Emonitor. In general, if the filter you want to use is available in both Emonitor and in the data collector, it is to your advantage to use the hardware filter in the data collector.
Setting Up Measurements 35 ESP filters Use an Envelope Spectrum Processing (ESP) filter to detect bearing and other component defects. The ESP filters apply a band pass filter, envelope the time domain signal, and then perform a frequency analysis on the result. ESP filters are built into the Enpac Ex, and you cannot change them in Emonitor. You can use ESP filters with the following measurement definitions: • Magnitude • Spectrum The following ESP filters are available with Emonitor and the Enpac Ex. 0.
36 Setting Up Measurements Emonitor uses a high pass filter with one of the low frequency cutoff shown in the table below. It uses the filter whose cutoff is greater than or equal to the result of the formula. Integrated (A to V, A to D, V to D) Non-integrated (A, V, and D) 0.36 Hz (21.6 CPM) 0.18 Hz (10.8 CPM) 5.30 Hz (318 CPM) 2.67 Hz (160.2 CPM) 23.80 Hz (1428 CPM) Order (Magnitude) filters Use order filters to define the bands around orders for magnitude and magnitude+phase measurements.
Setting Up Measurements 37 • Smart HP - (Smart High Pass) Typically this filter maps to a specific high pass filter in the data collector and is available for magnitude, spectrum, and time waveform measurements. In the Enpac Ex, it maps to the Enpac filters shown in the table below, depending on the results of comparing the filter choice to the formula below. Emonitor uses the following formula.
38 Setting Up Measurements EXAMPLE 2--------------------------------------× 30,000 CPM60000 = --------------- = 150 CPM = 2.5 Hz 400 lines 400 Emonitor uses the 5.30 Hz (318 CPM) filter for an integrated measurement. It uses the 2.67 Hz (160.2 CPM) filter for a non-integrated measurement. IMPORTANT The available filters in Emonitor depend on the data collectors you select as active data collectors using Tools > Set Active Collectors.
Setting Up Measurements 39 Figure 3.3 RSS filter Select to use the RSS filter IMPORTANT Using the 0.36 Hz (21.6 CPM) low cutoff filter for integrated measurements or the 0.18 Hz (10.8 CPM) low cutoff filter for non-integrated measurements will always cause the Enpac Ex to go into a long autorange mode. Only use these filter settings when very low frequency data is required. Measurement Units Emonitor and the Enpac Ex support many different measurement units.
40 Setting Up Measurements Measurement definitions are controlled in part by the collection specification (Setup > Collection). You select the collection specification when you set up the measurement definition. You can create new collection specifications based on your specific measurement using Setup > Collection. Setting Up Collection Specifications Figure 3.
Setting Up Measurements 41 The table for the transducer specification in the STD (Hz) 2000 collection specification would look like this. Table 3.2 Transducer specification in STD (Hz) 2000 collection specification Name Base Unit Input Type Units DC Offset Accelerometer Acceleration ICP Accel g’s 0 Measurement Input Types The input type is part of the transducer specification (Setup > Calibration). The transducer is part of the collection specification (Setup > Collection).
42 Setting Up Measurements Measurement Window Types The measurement window type is part of the collection specification (Setup > Collection). See Figure 3.4 on page 40. You select the collection specification when you set up the measurement definition. Emonitor and the Enpac Ex support the following measurement window types. In general, the Hanning measurement window provides the best compromise of frequency and amplitude accuracy for most predictive maintenance measurements.
Setting Up Measurements 43 • Peak-Peak - Use for detection of displacement; sometimes used for high frequency energy. This is the peak-to-peak (minimum to maximum) amplitude of a sine wave at the frequency of interest and is calculated from the RMS value. • True Peak - Use to detect impacts and random transients. The dynamic time signal contains the absolute value of the largest peak (positive or negative) within a specified time window. Returns a magnitude value only.
44 Setting Up Measurements You can either select a value from the drop down list, or you can enter a value in Maximum frequency in the Collection Specification dialog box. If you enter a value that does not match one of the values above, Emonitor uses the next higher maximum frequency. Measurement Resolution The measurement resolution is part of the collection specification (Setup > Collection). See Figure 3.4 on page 40. You select the collection specification when you set up the measurement definition.
Setting Up Measurements 45 Next, find the total collection time for the time waveform measurement using this formula. spectral lines collection time = ------------------------------Fmax (Hz) EXAMPLE If you had a Maximum frequency value of 7200 CPM and a Number of lines value of 400, you would: 1. Convert CPM to Hz. 7200 CPM------------------------= 120 Hz 60 2. Find the total collection time. 400 lines --------------------= 3.
46 Setting Up Measurements Setting Up Measurement Definitions The topics in this section describe setting up different types of measurement definition in Emonitor for your data collector. The topics describe the way Emonitor works with the Enpac Ex for each different type of measurement definition.
Setting Up Measurements 47 Collecting magnitude measurements in multiple frequency bands You can set up multiple measurement definitions at a location to collect magnitude values for individual frequency bands. Use band filters to define the different frequency bands in the measurement definitions. Make sure you select None in the Band Filter dialog box. This forces the Enpac Ex to collect a spectrum measurement.
48 Setting Up Measurements Figure 3.8 Magnitude with multiple frequency bands measurement definitions The filter specifications are shown in the table below: Table 3.7 Filter specifications for magnitude with multiple frequencies Name Low Cutoff High Cutoff Data collector filter type 0.8-1.2 Order 0.8 Orders 1.2 Orders None 1.2-3.5 Order 1.2 Orders 3.5 Orders None 3.5-8.5 Order 3.5 Orders 8.5 Orders None 8.5-50% Fmax 8.
Setting Up Measurements 49 • The Enpac Ex may display a phase value that differs from the value that appears in Emonitor by up to one degree. • Phase and magnitude measurements at orders require an external trigger signal. WARNING Do not connect the Enpac Ex to an external trigger unless the area is known to be nonhazardous. To set up multiple measurement definitions for magnitude and phase You create only one measurement definition for magnitude and phase at each order.
50 Setting Up Measurements 7. Move down to the next empty row in the measurement definition spreadsheet, and select Edit > Paste to paste the copied measurement definition. 8. Edit the new measurement definition by changing the measurement filter. Select a band filter centered on the next order. 9. Repeat steps 6 and 7 to create measurement definitions for the desired orders. You can then include these measurement definitions in a list and load it to the data collector.
Setting Up Measurements 51 Table 3.10 Filter specifications in mag & phase measurement definitions Name Low Cutoff High Cutoff Data collector filter type 2nd Order 1.8 Orders 2.2 Orders None 3rd Order 2.8 Orders 3.2 Orders None 4th Order 3.8 Orders 4.2 Orders None Numeric (Process) Measurement Definitions Emonitor and the Enpac Ex support numeric measurement definitions.
52 Setting Up Measurements Temperature measurements • Set up a temperature measurement definition by setting Data Type to "Numeric" and Units to "RPM," "CPM," or "deg. C." • Set up the temperature transducer in the Transducer Calibration dialog box with Input type set to "DC Coupled" and Units to "deg. F" or "deg. C." Make sure you enter the Calibration value that converts the voltage to a temperature. • Set up the collection specification to include a Signal detection of "RMS.
Setting Up Measurements 53 The following table shows the transducer specifications in the collection specifications. Table 3.12 Transducer specifications in numeric collection specifications Name Base Unit Input Type Units Calibration Value DC Offset Temperature Temperature DC Coupled deg. F See note below. 0 Tachometer Frequency DC Coupled RPM See note below. 0 Manual Entry None Manual Entry None See note below.
54 Setting Up Measurements Order normalized spectra in the Enpac Ex • Order normalized spectrum measurements have a frequency axis based on multiples of the running speed (orders). This quickly identifies the frequency relationship between each measured vibration amplitude and the running speed of the machine. It is particularly useful on variable speed machinery. • An order normalized spectrum measurement requires a trigger input to the Enpac Ex.
Setting Up Measurements 55 • You must set Trigger to "Yes" for any alarms you want to appear in the Enpac Ex during data collection. If you set Trigger to "Yes" for two or more alarms for the same measurement definition, Emonitor combines the alarms before sending the combined alarm to the Enpac Ex. • For more on how Emonitor combines alarms before sending them to the Enpac Ex, see Alarms and the Data Collector on page 60. The Enpac Ex does not support spectrum alarms.
56 Setting Up Measurements Time Waveform Measurement Definitions Emonitor and the Enpac Ex support time waveform measurement definitions. This topic lists the unique characteristics of the Enpac Ex that you may need to know when setting up and collecting time waveform data. • The Enpac Ex cannot collect phase with time waveform measurement definitions. • You can choose to have the Enpac Ex collect a time waveform only if a magnitude measurement at the same location is in alarm.
Setting Up Measurements 57 Next, find the total collection time for the time waveform measurement using this formula. spectral lines collection time = ------------------------------Fmax (Hz) EXAMPLE If you had a Maximum frequency value of 7200 CPM and a Number of lines value of 400, you would: 1. Convert CPM to Hz. 7200 CPM------------------------= 120 Hz 60 2. Find the total collection time. 400 lines --------------------= 3.
58 Setting Up Measurements Typical time waveform measurement definitions Figure 3.12 shows the setup for a typical time waveform measurement definition. Figure 3.12 Time waveform measurement definitions The following table shows the collection specification. Table 3.
Setting Up Measurements 59 Typical voltage measurement definitions Figure 3.13 shows the setup for three typical voltage measurement definitions. Figure 3.13 Voltage measurement definitions The following table shows the collection specifications. Table 3.
60 Setting Up Measurements several factors.
Setting Up Measurements 61 Supported alarms with the Enpac Ex This list describes alarms the Enpac Ex supports, alarms it does not support, and substitutes for some of the unsupported alarms. • The Enpac Ex supports above, below, in window, and out of window magnitude alarms for magnitude and numeric measurements. • You cannot select a magnitude out of window alarm in Emonitor. You must create one by combining an above and a below alarm for the same measurement definition.
62 Setting Up Measurements Loading inspection codes to the Enpac Ex You can load and remove inspection codes. • You must load the inspection codes when you load a list. You do this by selecting Load inspection codes in the Load Options dialog box. If you do not select this option, no inspection codes are available for measurements from the list or for unscheduled measurements associated with the list. • You can remove the inspection codes from the Enpac Ex by initializing the data collector.

Appendix C Frequently Asked Questions and Answers Appendix C contains the most frequently asked questions about using the Enpac Ex with Emonitor.
118 Frequently Asked Questions and Answers As an example, there are certain filters available in the Enpac Ex. Then there are three possible cases: • You select the Enpac Ex as the only active collector. Emonitor displays the correct filters in the measurement filter column of the Measurement Definition pane. • You do not select any active collectors. Emonitor displays many more filters than are available for the Enpac Ex. • You select two or more active collectors.
Frequently Asked Questions and Answers 119 • Click the D.C. Functions button then click Delete list. If the selected list(s) have data that has not been unloaded, you will lose both the selected lists and associated data. Why won’t Emonitor load a list to the Enpac Ex? First, check the communication between Emonitor and the Enpac Ex. Note that the baud rate setting in the data collector must match the baud rate setting in Emonitor.
120 Frequently Asked Questions and Answers The communication link remains until you do one of the following to break communication. • Close the Load/Unload dialog box in Emonitor. • Disconnect the cable between the computer and Enpac Ex. • Press the READ/OK key on the Enpac Ex. TIP Collecting Data with the Enpac Ex Emonitor indicates when it completes the loading or unloading process.
Frequently Asked Questions and Answers 121 Why are the alarms in the Enpac Ex not what I selected? You select the alarms you want to load with a measurement definition in Emonitor by setting the Trigger column to "Yes" for the alarm. If you select an alarm that the data collector can handle, Emonitor loads that alarm into the data collector when you load the list. Why aren’t inspection codes available for a list? You must load the inspection codes into the Enpac Ex before they are available for a list.
122 Frequently Asked Questions and Answers How do I clear data from lists after unloading? The Enpac Ex allows you to clear data from a list in the Enpac Ex after unloading it to your Emonitor database. This enables you to collect the list again as needed. Simply select the Clear list on unload check box in the Unload Options dialog box. Another method is to use the Clear data from list function in the Data Collector Functions dialog box.
Glossary active data collector You can define one or more data collectors as active. Emonitor uses the active collectors to determine the valid options when you set up measurement definitions. Suppose you had two active data collectors: DC1 can measure velocity in both in/sec and mm/sec DC2 can measure velocity only in in/sec The only choice you would see for velocity units would be in/sec, because that is common to both active collectors.
Glossary 124 band alarm An alarm that operates on defined frequency bands in a measurement. Each band can have its own alarm levels. The band definition determines whether the alarm in each band is set on the band maximum amplitude or the band sum. band filter A filter to use during data collection to help obtain high quality data. You can use a band filter (high pass. low pass, or both) or a percentage filter to remove specific frequency ranges from the measurement.
Glossary 125 current data collector Emonitor can communicate with only one data collector at a time. This data collector is called the current data collector. You can select only one current collector for load and unload operations. TIP G The current data collector is different from the active data collector. current list The most recently recalled or created set of measurement definitions held in the computer’s memory or saved on the computer’s hard disk.
Glossary 126 full scale value The maximum expected amplitude (Y-axis) value for the data. If the data exceeds the full scale value, it may not be possible to display or collect the full amplitude range without adjusting the full scale value. In general, the full scale should be the smallest value that is greater than the largest possible amplitude of the data. harmonic cursors Multiple cursors that are at constant multiples of a fundamental frequency.
Glossary 127 list type List types allow you to group lists by their function. For instance, you might group lists like this. Purpose List type Everyday data collection Scheduled In-depth assessment Diagnostic One-time collection Temporary List window A window that contains a display of locations in the current list. A list is a set of measurement definitions. You can open only one List window, and the List window cannot be split into panes.
Glossary 128 measurement A measurement is a single reading collected from a location and controlled by a measurement definition. Measurements are usually collected with a data collector, and stored in the database. The measurement may be magnitude data such as an overall displacement value, spectrum data such as a single acceleration spectrum, or some other kind of data. measurement definition A measurement definition is a set of parameters that controls the collection of a measurement.
Glossary 129 plot A plot is a graphical display of data. Some examples are spectrum, trend, and time plots. process (DC) voltage measurement A single valued measurement taken directly from a DC voltage output. Similar to a process measurement; however you directly measure the value instead of entering it with the data collector keypad. Quickload list A list of measurement definitions to be loaded into a data collector.
Glossary 130 spectrum measurement A measure of amplitude versus frequency, typically vibration for monitoring systems. Spectrum measurements are useful for identifying the contribution of individual components (bearings, fans, gears, etc.). It is much easier to separate elements of vibration in the frequency domain than in the time domain. spectrum plot A spectrum plot is a graph of amplitude versus frequency.
Glossary 131 trend plot A trend plot is a graph of the amplitude of a measurement against time, usually displaying the trend in a magnitude or process measurement over days, weeks, or months. unload report A report that Emonitor automatically creates after you unload data from a data collector or import data from a file. The report uses the list of measurement definitions unloaded from the data collector or imported from the file.
