Paragraphs Paragraphs are numbered sequentially with the first number corresponding to the Chapter number, the second number corresponding to the topic, and the third indicating number paragraph within that topic. Alpha characters indicate subparagraphs of the main paragraph. 1.2 RECORDER DESCRIPTION 1.2.1 General The Eagle Class Recorder™ are easy-to-use, true RMS, micro-computer-based voltage, amperage and power recording device that produce accurate readings and professional reports. These recorders can help you resolve customer voltage and power quality complaints, record flicker, conduct long-term voltage and current surveys, and detect voltage and current variations as brief as one cycle. The Recorders will not disrupt normal power supply; rather, it uses a minimal amount of voltage from one of the lines it is monitoring. Each Recorder gathers and stores stripchart data, recording the average, minimum and maximum readings for a selected interval with one-cycle resolution. Even events lasting less than one cycle are revealed in WinScan™ reports if the Recorder is configured to capture the information. The Recorder also calculates derivative power measurements such as power factor, phase angle, reactive power, and others. Installing the Recorder is relatively simple, although using the unit requires the same attention to safety as working with any other high-voltage device. Once the unit has been installed and the data you need have been recorded, the data can be downloaded using either serial cable or Bluetooth wireless technology. Real-time data can be checked using a Palm® operating system PDA. Please refer to the PalmView manual for further information. You can then view and analyze the data using the WinScan™ software. With the software you can create an array of graphs and reports, each of which provides you with useful, clearly presented power data. Figure 1-1: Eagle Class Recorder™

Eagle Class PQ Wireless ™ Digital Recorder Manual 15Table 2-1: Environmental Precautions ENVIRONMENTAL PRECAUTIONS For optimum performance, observe the following precautions when selecting a storing environment for the Recorder. • Avoid direct sunlight and high temperature. Operating temperature must be within -20°F to 135°F (-29 to 57°C). • Avoid sudden temperature swings of 10°C or more. • Avoid locations susceptible to vibration, shock, static electricity, high magnetic, electro-magnetic, or radiation fields. • Avoid extremely dusty, dirty, or corrosive gas environments. • Maintain adequate air circulation paths to ensure proper cooling of the unit. Ambient operating temperature should not exceed 135°F (57°C). Detailed Specifications are included in Chapter 1, Table 1-1,2,3. 2.3 WIRING SPECIFICATIONS AND PROCEDURES 2.3.1 Power Requirements The Recorder operates on voltages from 80 to 600Vac, 45-65 Hertz. A. Recorder Operating Power Connection Power connections to the Recorder are made by connecting the Phase A voltage signal input wiring to an appropriate signal of 80-600Vac. This will automatically charge the batteries (Batteries could take up to 14 hours to fully charge) and power up the Recorder. B. Batteries and power The Recorder, when installed, powers itself from the line voltage on Channel 1. It requires less than 1.5 watts. This means the Recorder does not contain large internal batteries that must be recharged or replaced; the Recorder can be retrieved from the field, downloaded, and reinstalled elsewhere minutes later. A small, AAA NiMH battery takes care of the Recorder’s minimal power needs during a power outage while the Recorder is in record mode. This battery recharges off Channel 1 and should be replaced every three years. In addition, a Li memory backup battery allows the Recorder to sit on a shelf for up to three years after being initialized and still be ready for installation. Its memory can also hold recorded data for up to three years. A 12-volt power adapter is provided to power the Recorder during downloads in the office or in the field if the Recorder has been disconnected from the line voltage. The AAA battery will run the unit for up to 2 hours if power is lost. WARNING
Eagle Class PQ Wireless ™ Digital Recorder Manual 16 WHEN CONNECTING THE SIGNAL MEASURING LEADS, BE CAREFUL NOT TO TOUCH ANY OF THE CONNECTION POINTS. LETHAL VOLTAGE AND CURRENT CAN EXIST ON ANY INPUT LEAD OR CONNECTION POINT. 2.3.2 Installing the Recorder This chapter explains the physical installation of the Eagle Class Recorder™. Installing the Recorder is not difficult for a professional familiar with similar equipment, although the same care required when working with any high-voltage equipment must be taken to complete the job safely. Please take the time to read Safety Issues, page 6, before installing the Recorder. There are two things to connect when installing the Recorder: 1. The current probes, and 2. The alligator voltage clip leads. Installation of the current probes depends on whether your Recorder is equipped with these items. Please read through the next three sections before installing your Recorder. Disconnect the power from the lines you plan to monitor until the installation is complete. Also, connect channel 1 voltage last, as this will start the two minute countdown for recording. A. The current probes 1. CTs The optional TLAR current clamps connect to the nine pin connector on the side of the Recorder housing. The Recorder automatically detects the amperage rating of the clamp connected during the two-minute initialization countdown which starts when power is applied to the unit (see below). The Eagle Class Recorder™ Recorder can be equipped with current clamps rated for 10A (TLAR), or Flexible CTs that have multiple ranges of 100A, 1000 or 5000A. Once the desired clamps are properly connected to the Recorder, clamp around the line or bus you wish to monitor. The arrow on the body of the current clamps or probes must point toward the customer (away from the utility)—in the direction of the current. The current clamps measure amperage through induction. PMI recommends that current clamps be connected to the Recorder whenever they are attached to a power line. 2. Installation of Flexible CT Insert the connector of the Flex CT into the 9-pin connector on the side of the recorder. The cable branches to 2, 3 or 4 flexible clamps, each of which is snapped into a loop around each line to be monitored. The “smart box” midway on the cable senses the induced current and processes the information for measurement. The recorder’s current range can be set using WinScan or PMIScan. Remember, Safety is always our primary concern. C. The voltage clip leads The Recorder can monitor voltage on up to four channels. Alligator clip leads are provided for each channel. These leads are color-coded as follows: Table 2-2: Voltage leads color coding Channel Lead Phase Channel 1 Black A Channel 2 Red B Channel 3 Blue C Channel 4 Yellow N Common White Common
Eagle Class PQ Wireless ™ Digital Recorder Manual 17Attach the alligator clip leads to voltage lines in a pattern which will monitor the phases on which you wish to collect data. For information on several ways to monitor power, see the next section, Connecting to different types of services. The Recorder will borrow its power from the voltage on Channel 1. As soon as voltage is applied to the Channel 1 lead, the Recorder begins a two-minute countdown. During this countdown, the Recorder will sample the voltages on each channel in order to set the nominal voltage for the recording period. The Recorder also uses this time to detect which probes are connected to it—see the information on current probe connections above. While the countdown continues, you may adjust some Recorder settings. However, making a change to the Recorder settings will restart the countdown at two minutes. During the two-minute countdown, you may exchange one type of current clamp for another (on the Eagle Class Recorder™ only). However, if you change the probes, you must restart the two-minute initialization countdown by interrupting and then restoring power to the Recorder. If probes on an operating Recorder are exchanged with probes of a different type without re-initializing the Recorder, the unit will retain the setting of the first probes as the operating type. This may result in incorrect measurements. 1. Connecting to different types of services - When planning how to connect your Recorder, keep the following things in mind: • The banana jacks are color-coded by channel: black is Channel 1, red is Channel 2, blue is Channel 3, yellow is Channel 4, and white is common. • The unit is powered from the voltage between Channel 1, the black jack, and common, the white jack. For this reason, even if you are not connecting all the input wires, Black and White must be connected. • Be aware of the input voltage warning label on the Recorder, do not exceed the maximum input voltage. The limits are 600 volts RMS channel to channel or channel to common for the Eagle Class Recorder™. • You may use four-channel units to monitor five-channel systems; naturally, you will record data for only four of the channels. Conversely, you can use a four-channel unit to monitor a single-phase system: either unplug the unused leads, connect them in parallel so that all channels are recording the same information, or clip together to avoid noise readings. Again, the Channel 1 leads must be connected in order to power the unit.. Below are diagrams showing several basic circuits and possible ways to connect them: To connect a Recorder to monitor a delta service, connect one of the clips leads for three channels to both corners of the phase. Clip lead for Channel 1 (black) will be connected to one corner (A). Clip the White lead to the next corner (B), and clip the blue lead to the third corner (C). Figure 2-1: 3 Wire Delta
Eagle Class PQ Wireless ™ Digital Recorder Manual 18 Figure 2-2: 4 Wire Delta You can connect the clip leads phase-to-phase on a Wye service in the same manner you would when monitoring a delta service. Figure 2-3: 3 wire wye phase to phase
Eagle Class PQ Wireless ™ Digital Recorder Manual 19Figure 2-4: 4 wire wye You can also connect the unit to monitor phase-to-neutral references by connecting one lead (the hot side) for each channel to the respective phase in the circuit, and connect the white lead (common) to the neutral. In the diagram, Channel 1 is represented by the black lead, Channel 2 (red) , and Channel 3 (blue).
Eagle Class PQ Wireless ™ Digital Recorder Manual 20Figure 2-5: Two phase three wire Figure 2-6: 2.5 Element Z-coil 2.3.3 Communications Port Connections A.

Eagle Class PQ Wireless ™ Digital Recorder Manual 22An outline of WinScan™ Chapter 4 4.1 RETRIEVING DATA FROM THE RECORDER After your Recorder has finished collecting data, you need to download the data in order to analyze it on your computer. This process can be accomplished either over blue tooth (if your PDA or computer have a Blue tooth device) or via a serial cable. As the data is downloaded, your computer will save it in a file which can later be opened and analyzed. Please refer to the WinScan™ Manual for instructions. Figure 4-1 illustrates the basic structure of WinScan™. As you can see, the main menu option HELP leads to information on the program, while the option FILE leads to operations involving the Recorder, the data it collects, and the tools needed to interpret that data. The most useful options in the FILE menu are RECORDER CONTROL and LOAD. As shown in the diagram, RECORDER CONTROL leads to options which adjust settings on the Recorder and computer. These options regulate the collection and retrieval of data by the Recorder. The other important option, LOAD, is the gateway to creating, viewing and printing WinScan™ graphs and reports. Familiarize yourself with all the operations of WinScan™ as described in this manual before attempting to use your Recorder. After you are familiar with WinScan™, use the Quick Guide, in the WinScan™ Manual, as a reminder of the steps required for certain operations. For your own protection, please take the time to read Safety Issues, before installing or operating the Recorder.Main MenuProgram InfoCreate, viewand printgraphsScannersettingsCreate, viewand printreportsComputersettingsLoad ScannerConnectHelpFileData retrieval Figure4-2: Software outline
