Do not install or operate near open bodies of water. The Eagle 120 is intended for use with a standard, indoor, 15 amp 120VAC receptacles. Do not use outdoors or in a wet location (as determined by the National Electrical Code). The Eagle 120 Recorder is intended for use with a standard 15 amp receptacle. The USB port is optically isolated from the 120VAC line. However, to insure user safety and prevent damage to the unit, only the supplied Eagle 120 Recorder USB cable should be plugged into this jack. The other end of the USB cable should only be plugged into an USB port. The Eagle 120 Recorder contains a lithium battery. This battery is not user replaceable. Follow all applicable regulations concerning disposal of batteries if the Eagle 120 Recorder is discarded, or return the unit to the factory for disposal. Although the Eagle 120 Recorder Voltage has been designed and built to be as safe as possible, great care should be exercised at all times during operation and installation. The National Electric Code should be followed at all times. The Eagle 120 convenience receptacle is rated at 15 amps, for use with a 15 amp branch circuit. As per the National Electric Code, the maximum allowable load on this receptacle is 12 amps. When the Eagle 120 is plugged into a 120VAC receptacle, this voltage is present on the convenience outlet. Use the same caution with this convenience outlet as with any 120VAC source. Do not use this outlet where normal breaker operation could cause a loss of power to life-critical equipment or cause a dangerous situation to exist. A three-wire to two-wire isolation adapter may be used with the VP-2 to plug the Eagle 120 into a two-wire receptacle with no earth ground. If this is done, the ground on the convenience receptacle is not connected to earth ground. Do not plug devices which require an earth ground into the convenience receptacle if this grounding scheme has been defeated. The Eagle 120 is not designed for use with medical equipment or situations where life-critical equipment is being used. The convenience outlet in the Eagle 120 is not a hospital grade receptacle. Do not use near heat sources such as radiators and electric heaters. 3 Getting Started with the Eagle 120 power quality analyzer The Eagle 120 power analyzer is an electronic monitoring device which plugs into a standard 15 amp receptacle. The unit measures and records voltages from line to neutral and neutral to ground. The Eagle 120 power quality analyzer powers itself from the 120V line. After data has been recorded, the unit is connected to a PC with a USB cable. ProVision, the PC data analysis software, is used to extract the data from the Eagle 120 power analyzer. With ProVision, data may be graphed, turned into reports, and exported to spreadsheets. 3.1 Contents of the Eagle 120 power quality analyzer Package The Eagle 120 power analyzer is packaged with the following items: • The Eagle 120 power quality analyzer • CD-ROM containing ProVision and all documentation • USB communications cable . If any of these items are missing, please call PMI immediately. The CDROM includes the latest version of ProVision, example data files, and documentation for ProVision and all power analyzers in Adobe Acrobat format, Acrobat reader, and the latest firmware for all Voltage power quality analyzers. 3.2 Installing the PC software (ProVision) Insert the CD-ROM into your CD drive. If the installation program doesn’t start automatically, run setup.exe from the CD. The installation program will guide you through the rest of the process. 3.3 Eagle 120 power analyzer Operation Using the Eagle 120 power quality analyzer consists of initialization, installation, monitoring, downloading, and analyzing. First, the Eagle 120 power analyzer is initialized with parameters appropriate for the recording session. These parameters include voltage thresholds, flicker limits, and a graph time interval, among others. These parameters are set using ProVision. After sending the initialization to the Eagle 120 power quality analyzer, it is ready for installation in a receptacle. When plugged in, the Eagle 120 power analyzer begins a 60-second countdown. After the countdown, the Eagle 120 power quality analyzer starts monitoring. Later, after the desired data is recorded, the data from the Eagle 120 power analyzer is downloaded into ProVision. ProVision is then used to analyze and save the data. The Eagle 120 power quality analyzer may be reinitialized 4 Using the Eagle 120 power analyzer 4.1 Initialization The Eagle 120 power quality analyzer must be initialized before monitoring data. This is done by connecting the Eagle 120 power analyzer to your PC with the Eagle 120 power quality analyzer USB cable, and running ProVision. See the section “PC Communications with the Eagle 120 power analyzer” for information on how to connect the Eagle 120 power quality analyzer to the PC. See the ProVision documentation for details on how to initialize a Voltage power analyzer. 4.2 Installation Please read the safety section before installation. Always exercise extreme caution when installing an Eagle 120 power quality analyzer. Install the Eagle 120 power analyzer in the receptacle socket by sliding the blades of the power quality analyzer into the receptacles in the outlet. If you wish to monitor a load, plug in it’s AC cord into the front of the power quality analyzer.When the power quality analyzer is plugged in, the LED on the front of the power quality analyzer will start blinking. This indicates that the one-minute countdown to monitoring is in progress. At the end of the countdown, the power quality analyzer will begin monitoring information. The LED will blink once every six seconds to indicate that the countdown is complete and the unit is monitoring. Note: If you have interrupted power to the receptacle during installation, the countdown will not begin until the power is reapplied. 4.4 Downloading Data After the Eagle 120 power analyzer has recorded the desired data, it is downloaded into ProVision or a Palm PDA. The Eagle 120 power quality analyzer may be downloaded in the field by connecting the USB cable into a laptop (see PC Communications with the eagle 120 power analyzer). The Eagle 120 power quality analyzer stops monitoring when a PC is connected to the USB port and “Identify” is selected in ProVision. The data is then downloaded into ProVision. If the USB cable is unplugged from the Eagle 120 power analyzer, the Eagle 120 power quality analyzer will continue monitoring, appending data to the existing monitoring session. If the Eagle 120 power analyzer is re-initialized, it will start a 60-second countdown. The Palm PDA can also download a Eagle 120 power quality analyzer via the Blue tooth wireless communications (if the Eagle 120 has that option installed)– no cable is needed. The Eagle 120 power analyzer also may be downloaded later. Simply remove the unit from the outlet and take it back to the offi ce. The Eagle 120 power quality analyzer automatically stops monitoring when it is disconnected from an outlet. The recorded data is held in non-volatile memory so no data is lost. When the Eagle 120 power analyzer is back in the office, connect it to a PC with the USB cable, then plug the power quality analyzer into an outlet. The green LED lights up steadily in this mode to indicate that it is in communications mode, and ready for downloading. The recorded data is still in the Eagle 120 power analyzer and can be downloaded again even after it has been re-initialized. The old data is not erased until the end of the 60 second countdown of the next monitoring session. 4.5 Analyzing Data See the ProVision documentation to learn about using ProVision to analyze Voltage power quality analyzer data. The documentation is located in the “Manuals” folder on the ProVision CD-ROM. 4.6 PC Communications with the Eagle 120 power analyzer The Eagle 120 power quality analyzer may communicate with ProVision running on a PC or laptop to receive its initialization and to download data. Use the supplied power analyzer USB cable to connect the Eagle 120 power quality analyzer to a PC. Plug the connector into an available USB port on the PC. Plug the other end of the USB cable into the jack on the bottom of the Eagle 120 power analyzer. The green LED lights up steadily in this mode to indicate that it is in communications mode, and ready for communications. In ProVision, the power quality analyzer serial number will appear within 2 minutes automatically in the devices window. The Eagle 120 power analyzer and ProVision are now ready for communications. For details on how to use ProVision to initialize and download a Voltage power quality analyzer, see the ProVision documentation located on the CD-ROM. The Eagle 120 power analyzer does not have a modem. References to modem communications in the ProVision documentation do not apply to the Eagle 120 power quality analyzer. 4.6.1 Communications Troubleshooting Failure to establish USB communications is usually a result of a faulty PC setup or an improperly installed driver. Follow these steps to isolate and correct the problem. Make sure the Eagle 120 power analyzer is in communications mode. If the Eagle 120 power quality analyzer red LED is not lit steadily, the unit is not in communications mode, and will not communicate through the USB port. Make sure the cable is plugged firmly into the 6-pin female connector on the Eagle 120 power analyzer. Also check that the USB connector is plugged securely into the PC USB port. If the Eagle 120 power quality analyzer is in communications mode, the problem is probably on the PC side. A USB cable must be used to communicate directly with a laptop. 4.8 Using a Palm PDA Initialization: In order to initialize the power quality analyzer it must have power from the line the power quality analyzer is installed. Also, the PDA must be able to communicate with the power quality analyzer, by Bluetooth. Older power quality analyzers employed only the rs-232 cable, while newer Eagle 120 power analyzers may have Bluetooth installed as an option. Once the power quality analyzer is powered and the PDA is communicating with the power quality analyzer, tap the PMIScan icon to reach the Main Menu, consisting of 3 commands: LDU, Comm, and Files. 4.8.1 LDU This mode allows the user to scroll though a number of screens showing real-time display of the measurements that have been enabled: voltage, current, power, phase angle, power factor, displacement power factor, and harmonics are possible. The “1 Chan” display option shows the measurements on fewer screens than the “4 Chan” option, but both sequences show the same information. • Tap More to scroll through the measurements. • Tap Next to view other channels. 4.8.2 Comm This mode allows the user to perform 6 functions, most importantly Download and Initialize: 1) “Download” identifies the power quality analyzer in the heading, allows editing of the Identification, and leads to a download. • Tap Done and OK to initiate the download. See “Downloading Data” below. 2) “Identify” lists information about the individual power analyzer. 3) “Date/Time” allows the user to synchronize the power quality analyzer with the PDA. • Tap Set Time to change the Date/Time of the PDA. 10 4 USING THE Eagle 120 power analyzer 4) “Initialize” allows the user to set parameters and choose options from a of screens similar to those in ProVision. By default, “power quality analyzer Settings” shows the recommended or usual quantities. • Tap Edit to change the settings. • Tap Previous or Next to scroll through the numbered screens. • Tap Done and OK to accept the defaults or the user-selected settings. 5) “Retrieve Set” uploads the prior group of settings. 6) “Done” leads back to the Main Menu and accepts the chosen settings. 4.8.3 Downloading Data When the Technician wishes to collect data from the power quality analyzers in the field, the PDA serves as a storage medium to convey the data to the office PC. Depending on what records are enabled, the memory of the PDA holds downloads from several power quality analyzers. Connect the PDA to the power quality analyzer via Bluetooth. To implement the download: • Tap Comm, Download, and OK to initiate the transfer. Depending on the size of the file, the process could take several minutes. The download is complete when the Main Menu appears. Back at the office, the PDA may be connected to the PC through the HotSync docking cradle: • Connect the cradle to the PC according to the instructions for the Palm. • Place the Palm in the cradle. • Press the HotSync button, and the HotSync Progress screen appears. HotSync places the .isf file in the folder you specify during the installation program. The .isf file can now be opened and viewed as usual with the ProVision software: • Click on File, Open, and choose the file from the Open dialog box. 4.9 Eagle 120 power quality analyzer Options The Eagle 120 power analyzer is available with a number of options. All options are installed internally inside the Eagle 120 power quality analyzer housing. The most common option is the extended memory (8 MB). The Bluetooth option lets the Eagle 120 power analyzer to communicate wirelessly to a pc or a palm based PDA. Standard features include current, power, harmonics, and waveform capture. The currents are sampled just like the voltage channels, 256 times per cycle. These samples are used to create one cycle RMS values, and are recorded like the voltage channels. The Eagle 120 power quality analyzer contains 1 shunt to pick up the current signal from AC Hi– no external CTs or clamps are necessary. The power feature allows the Eagle 120 power quality analyzer to compute and record the power consumed by the loads on the service. Real power (watts), reactive power (vars), apparent power (volt-amps), and power factor are computed for each leg. These are computed using the voltages from line to neutral, and current through each leg. The power option also includes extra memory so that all the power quantities may be recorded without reducing the recording time. The Eagle 120 power analyzer must have current measuring capability to compute power. The Harmonics and Waveform Capture feature give the Eagle 120 power quality analyzer the ability to measure and record voltage and current harmonics, as well as raw waveform data. graphs of selected voltage and current harmonics may be recorded, up to the 51st, as well as daily profiles of total harmonic distortion. In addition, raw voltage and current waveforms may be captured based on trigger conditions set with ProVision. This option also includes extra memory so that harmonic graphs may be recorded without lessening the total monitoring time. 4.9.1 Eagle 120 power analyzer Serial Numbering The Eagle 120 power quality analyzer serial number indicates if Bluetooth has been installed. The addition of Bluetooth is signified by the serial number label containing a serial number above 45000 and a Bluetooth symbol. To see if extended memory is installed, connect to ProVision and identify the unit. . 5 What the Eagle 120 power analyzer Records 5.1 Introduction The job of any power monitor is to record all interesting data, and leave unrecorded the vast majority of boring, unremarkable data. The tricky part for a monitor is deciding which events are important. This is a problem of data reduction. A power quality analyzer that captured every 60 Hz waveform during a week’s monitoring would never miss an event, but would present the user with millions of useless cycles. Conversely, a power analyzer whose thresholds are set incorrectly may not record anything. Staying somewhere between these two extremes involves a balance of thresholds, settings, and record types. The monitor will see an enormous amount of data on its voltage and current inputs– the Eagle 120 power quality analyzer sees over 1 billion samples per day! Ideally, all this data is reduced to a small report which just shows the important events and measurements. The sifting of data into specific record types accomplishes this task. 5.1.1 Triggered Record Types PMI power analyzer records can be divided into two classes. The first is event driven. These record types are triggered by a combination of triggering logic and adjustable thresholds, usually voltage-based. If a trigger never happens, nothing is recorded for that record type. As more triggers occur, more records are collected for that record type. The advantage of this class is that nothing is recorded unless something happens. In the ideal case, no problems occurred, so nothing was recorded, and no data analysis is necessary. If a trigger did occur, then the monitor logged the event for later analysis. This is a powerful data-reduction tool, and can reduce huge amounts of data into a few small records containing all the significant events. The disadvantage is that success completely depends on good thresholds and settings. A threshold that is too tight will cause the power quality analyzer to log records that aren’t really worth analyzing. These extraneous records often hide the (hopefully) few important ones. A threshold that is too loose will cause the power quality analyzer to ignore important disturbances. Although it is often possible to use regulatory limits or other known standards to set thresholds, this can be a chicken-and-the-egg type problem: sometimes you need to know something about the disturbance before you can set proper thresholds to capture it. Despite these potential pitfalls, triggered record types are powerful tools in power line monitoring. They are most useful for capturing voltage disturbances and power quality problems. The captured events are usually presented in a text report. Triggered record types include Power Outage, Abnormal Voltage, Event Change, Significant Change, and Waveform Capture. 5.1.2 Non-triggered Record Types The second class of record types is not event driven. These record types are always logging data, regardless of how interesting or important the data is. The classic example is a paper graph, which continuously logs data. There are no thresholds to set, although there may be a parameter to determine how often to collect data. The logged data is usually presented as a graph of data points. Although there may be a large amount of data, using a graph lets the eye pick out important data. Problems such as sags and swells are easy to see in the graph graphs. In addition to voltage quality studies, these record types are used for finding daily trends in current or power values, measuring power factor, etc. The advantage of not having thresholds to set is that there is no question about what data will be recorded. The disadvantage is that sometimes there is no question that a lot of data will be recorded, most of it unimportant. For non- power quality data such as power factor measurement, there is no disadvantage. These record types include graphs, Daily Profiles, Histograms, and Energy Usage. 5.1.3 Using the power quality analyzer The PMI power analyzer can record every available record type simultaneously. Each record type has its own fixed memory allocation, so there is no danger of one errant record type filling the power quality analyzer memory to the exclusion of other record types (for example, Event Capture can never overflow into graph memory). Thus the choice usually isn’t what to record types to record, but what record types to examine. In order to answer that question, a good understanding of each record type is required. The details of each record type, and potential uses, are described in the ProVision manual. 6 Warranty Clause Power Monitors Inc.
