Page 2 Chapter 2 Introduction TASK 808 Chapter 2 Introduction to the PP4300/Task 808 The Task 808 is a TASKCard-based PP4300 application. The patented TASKCard is a removable flash memory card that is installed in the PP4300 and contains an operating system designed for a specific application (task). 2.1 PP4300 The Dranetz-BMI Power Platform 4300 is a portable, hand-held, TASKCard based, eight-channel power meter/monitor. The PP4300 is capable of monitoring, recording and displaying data for four voltage and four current channels simultaneously. n Refer to Chapter 3 Hardware Overview for illustrations and detailed descriptions of the various controls, indicators, and connectors. 2.2 The Task 808 Application The Task 808 is an application designed primarily for long-term demand and energy surveys. It is intended for use by electrical facilities plant personnel (engineers as well as electricians), energy management consultants and utility marketing services groups. 2.2.1 Task 808 Model Options Two Task 808 models are available: the 808/M (Memory) with expandable memory and the 808/H-M (Harmonics-Memory). NOTE - Any model-specific differences in descriptions or procedures will be documented throughout this manual. Task 808 - model M This model (808/M) provides all standard features, including 256K internal memory, plus memory card storage capability. Optional memory cards are available in various capacities, shown in Appendix C. 3 Page Chapter 2 Introduction TASK 808 Task 808 - model H-M In addition to all standard features, including 256K internal memory and memory card storage capability, this model (808/H-M) provides harmonics data, useful for determining the source and level of the effects created, e.g., by the many energy conservation devices in use today, such as electronic lighting ballasts and adjustable speed drives. 2.2.2 Task 808 Power Circuit Configurations When TASKCard 808-equipped, the PP4300 can monitor any of the following power circuit configurations: o Single phase o Split phase o Four wire wye o Floating or grounded delta o Open leg delta o High leg delta o Two-and-a-half element • WARNING: Refer to Appendix E Connecting Probes/Common Circuit Connections for detailed descriptions of common power monitoring configurations and probe connections. • ADVERTENCIA: Consulte el Apéndice E Conexión de sondas/Conexión de circuitos comunes para obtener descripciones detalladas sobre configuraciones comunes de monitorización eléctrica y conexiones de sondas. • AVERTISSEMENT: Se reporter à l’Annexe E, Connexion des sondes / Connexions simples des circuits, pour de plus amples détails concernant les configurations de contrôle de puissance et les connexions des sondes. • WARNUNG: Im Anhang E “Meßfühler verbinden/ Gängige Schaltverbindungen” finden Sie ausführliche Beschreibungen von gängigen Konfigurationen der Spannungsüberwachung und von Meßfühlerverbindungen. While monitoring any of the above configurations (except the three delta configurations), the PP4300 can also be connected to monitor neutral-to- ground voltage and neutral or ground current. Page 4 Chapter 2 Introduction TASK 808 2.2.4 EASY STARTTM Feature Both Task 808 versions come equipped with the EASY START feature which prompts users for a few key items of information about the circuit being monitored.

Step 4 At the bottom of the unit, position the TASKCard with the label facing front and the plug end facing the TASK CARD slot in the PP4300. Step 5 Insert the card fully into the slot until resistance is felt, then press firmly until card engagement is felt. NOTE - Do not force the card into the slot if no card engagement is felt. Remove card and check that there is no foreign object on or in the plug end of the card. Remove any obstruction. Reinsert card and repeat card engagement process. If card cannot be engaged, call Dranetz-BMI Customer Service for instructions. n Refer to Appendix H System Messages for description of TASKCard Error Messages which may be displayed when the unit is powered ON. 13 Page Chapter 4 Touring the Task 808 TASK 808 Chapter 4 Touring the Task 808 4.1 Preparing for the Guided Tours… Before jumping into the setup and operation of the Task 808, it is well worth taking a minute or two to review a few simple preliminaries which will help you get started when you begin the Guided Tours. 4.2 Screen layout All of the Task 808 screens have common elements, such as the following: Date Time Oct-17-96 18:34:45 CIRCUIT TYPE SINGLE PHASE Display Area SINGLE SPLIT 3PHASE 3PHASE 2-1/2 PHASE PHASE DELTA WYE ELEMNT EXIT Reverse Highlight Text Instructions (SOFTKeys) 15 Page Chapter 4 Touring the Task 808 TASK 808 In addition, whenever a graph is displayed, the vertical axis (and scale) for Volts will always be the left axis and the vertical axis (and scale) for Amps will always be the right axis, as shown below: VOLTS AMPS 4.3 Navigation Tips Navigation (moving from screen to screen) is accomplished in two ways: 1) Using SOFTKeys, sometimes in conjunction with the highlight bar, and 2) Selecting from numbered options. 4.3.1 Using SOFTKeys The six keys on the PP4300 immediately below the display area are called SOFTKeys and are used to execute the reverse highlight text instruction (such as, SELECT CHAN, METER MODE, SETUP) displayed immediately above each key. Some SOFTKeys move the highlight from field to field within the display area while other SOFTKeys are used to advance from screen to screen. Other SOFTKeys perform operations, such as, turning features ON and OFF. NOTE - Throughout this manual, references to SOFTKeys and their corresponding instructions will be combined into a single phrase, e.g., press the EXIT SOFTKey. Page 16 Chapter 4 Touring the Task 808 TASK 808 4.3.2 Numbered Options Several screens consist of a list of numbered options. Simply press the corresponding key on the PP4300’s numeric key pad to execute the desired option, e.g., press the 1 key on the “Setup” menu to select Easy Start: Jan-17-97 18:34:45 SETUP MENU 1.

The VOLTS ON/OFF and AMPS ON/OFF SOFTKeys are used to toggle between ON and OFF. The EXIT SOFTKey will implement the selection. 17 Page Chapter 4 Touring the Task 808 TASK 808 4.4 Data Entry There are two different methods for manually entering data, depending on whether the data is alphabetic or numeric. 4.4.1 Alphabetic Entry Alphabetic data must be entered to record the site/file name. Alphabetic data is entered using the special alphabetic entry screen shown below which will automatically be displayed when required: The arrow SOFTKeys are used to highlight desired letters (and SPACE, BACKSPACE, DELETE ALL). The ENTER SOFTKey moves highlighted letters into the small text window at the top of the display area until the site/file name is completed. 4.4.2 Numeric Entry Integers (whole numbers) must be entered to record dates, times and demand intervals. Decimals may be entered to record scale factors, sync parameters, vertical scales and to describe the application. Integers and decimals are entered using the numeric keys and the decimal point on the PP4300’s numeric key pad. 4.5 Help Screens Help screens are available for every screen in the application. Simply press the ? key (question mark key) on the numeric keypad and help for the active screen will be displayed. Page 18 Chapter 4 Touring the Task 808 TASK 808 On to the Guided Tours... Now that the preliminaries are completed, continue with the Guided Tours chapters to begin hands-on operation of the Task 808. Chapters five, six and seven are designed to take the user step by step through the complete setup and operation of the PP4300/Task 808: Chapter 5 Easy Start Tour - designed to implement a quick, no-frills setup using the programmed EASY START feature. Chapter 6 Advanced Tour - designed to implement a more sophisticated setup by building on the Easy Start setup. Chapter 7 Reporting Tour - designed to document the wide array of reporting features in the Task 808. Recommendation It is recommended that all three of the guided tours be taken, starting with the Easy Start Tour. 19 Page Chapter 5 Easy Start Tour TASK 808 Chapter 5 EASY START Tour The Easy Start Tour covers the following topics: 5.1 Prepare the PP4300 5.2 Connect the Probes 5.3 Power ON the PP4300 5.4 Easy Start -- Configuring/Monitoring 5.5 Viewing Data/Reports 21 Page Chapter 5 Easy Start Tour TASK 808 5.1 Prepare the PP4300 Step 1 Insert the Task 808 TASKCard into the PP4300’s TASKCard slot. n Refer to Chapter 3 Hardware Overview for complete TASKCard installation instructions. Step 2 Insert a formatted memory card (if applicable) into the PP4300’s memory card slot. n Refer to Appendix F Card Functions for complete memory card installation and formatting instructions. Step 3 Connect the AC adapter output cable to the DC INPUT connector on the right side of the PP4300. Connect the AC adapter power cord to an appropriate outlet. 5.2 Connect the probes • WARNING: Refer to Appendix E Connecting Probes/Common Circuit Connections for detailed descriptions of common power monitoring configurations and probe connections. • ADVERTENCIA: Consulte el Apéndice E Conexión de sondas/Conexión de circuitos comunes para obtener descripciones detalladas sobre configuraciones comunes de monitorización eléctrica y conexiones de sondas. • AVERTISSEMENT: Se reporter à l’Annexe E, Connexion des sondes / Connexions simples des circuits, pour de plus amples détails concernant les configurations de contrôle de puissance et les connexions des sondes. • WARNUNG: Im Anhang E “Meßfühler verbinden/ Gängige Schaltverbindungen” finden Sie ausführliche Beschreibungen von gängigen Konfigurationen der Spannungsüberwachung und von Meßfühlerverbindungen. Before powering ON and initiating the Easy Start tour, the probes must be connected. Before connecting anything, make sure that the circuit to be monitored has been de-energized. Page 22 Chapter 5 Easy Start Tour TASK 808 5.3 Power ON the PP4300 Step 1 Press the ON/OFF power button on the front panel of the PP4300 to turn the power ON. A screen with the results of self-diagnostic routines will be displayed briefly during power up. All of the self-diagnostic routine results should read PASSED. n Refer to Appendix H System Messages for description of TASKCard Error Messages which may be displayed when the unit is powered ON. Step 2 Wait for the next screen to be displayed: 23 Page Chapter 5 Easy Start Tour TASK 808 Depending on the PP4300 model in use, the message -- SELECT CURRENT PROBE(S)? -- may be displayed across the bottom of the screen, as a reminder, because correctly identified probe types and scale factors are essential to accurate computations. The “Scope Mode” screen is a gateway to four major functions of the system: Meter Mode, Harmonics (available to Task 808/H-M model users only), View Data and Setup. The “Scope Mode” screen also acts as a home screen from which to branch to other functions of the Task 808. NOTE - When the PP4300 is turned ON, it will always default to the configuration values in effect when the system was last powered OFF. Values for all eight channels will always be displayed initially on the “Scope Mode” screen. If the probes are changed while the unit is OFF, all monitored values will be erroneous until the probe and scale factor information is updated. The message – MONITORING: OFF -- may be displayed across the top of this screen (and across all other screens as well). This message indicates that the PP4300 is not monitoring any circuits, i.e., not recording event data (however, the “Meter Mode,” “Scope Mode” and “Harmonics” screens will still function properly with monitoring OFF). In addition to the obvious, i.e., when the currently active configuration specifies that monitoring is OFF, this message may also be displayed briefly under such circumstances as saving a changed configuration or during the self test. While monitoring is ON, no message is displayed. Setting the time and date will be covered in the Advanced Tour. Page 24 Chapter 5 Easy Start Tour TASK 808 5.4 Easy Start -- Configure/Monitor Easy Start guides the user step-by-step through a basic configuration process. The final step in the configuration process automatically initiates the circuit monitoring.

Press the EXIT SOFTKey to exit the “Meter Mode” and return to the “Scope Mode” screen. This completes the Easy Start Guided Tour. A Footnote on Powering OFF… NOTE - It is a wise practice to routinely display the “Scope Mode” screen before powering OFF the PP4300. Powering OFF from other screens may nullify configuration changes thought to be implemented. In such cases, the actual configuration, on a subsequent power up, could differ from the expected configuration. 33 Page Chapter 6 Advanced Tour TASK 808 Chapter 6 Advanced Tour The Advanced Tour covers the following topics: 6.1 Setup Menu 6.1.2 Set Programmable Features Menu 6.1.4 Memory Functions Menu 6.1.5 Set Input Configurations Menu 35 Page Chapter 6 Advanced Tour TASK 808 6.1 Setup Menu 6.1.1 Easy Start In Chapter 5 Easy Start Tour, EASY START was the only setup option which was explored. However, the Setup Menu contains many other powerful and important options for configuring the Task 808. Step 1 From the “Scope Mode” screen, press the SETUP SOFTKey. Jan-17-97 18:34:45 SETUP MENU 1.

NOTE - It is important that the time (24 hour format) and date is set correctly because they are used by the system to identify event data. If changing the time and data becomes necessary, you may wish to clear event memory as well, since any previously recorded events will have an incorrect time and date. When finished, press the EXIT SOFTKey to return to the “Programmable Features” menu. Step 4 Option 2 ENTER SITE/FILE NAME was reviewed previously during the Easy Start Guided Tour. Press the 3 key on the numeric keypad to toggle the display mode from NORMAL (blue text and graphics on white background) to INVERTED (white text and graphics on a blue background). Exit and return to this menu to see the implemented result. If Option 4 LCD BACKLIGHT AUTO-SHUTOFF is enabled, the screen will time out/dim after five minutes has elapsed without any keys being 37 Page Chapter 6 Advanced Tour TASK 808 pressed. Although pressing any key will restore the screen’s brightness, the 0 (zero) key is recommended because it is the least likely to affect anything (unintended exit, changing screens, etc.). Auto-shutoff extends battery life and its use is recommended. Option 5 AUDIBLE ALARM, when set to ON, the unit will sound a one- second beep for each event trigger and a 0.1 second beep for each error condition. Press the EXIT SOFTKey again to return to the “Setup Menu” screen. 6.1.3 Turn Monitoring ON/OFF Press the 3 key on the numeric keypad to toggle monitoring ON and OFF. Step 5 Press the 4 key on the numeric keypad to display the “Memory Functions” screen. 6.1.4 Memory Functions First, a word or two about memory… Before exploring the memory functions, it is essential that users get a good conceptual understanding of the Task 808’s data storage and memory management techniques. For this reason, the Advanced Guided Tour will take a brief detour at this point. Page 38 Chapter 6 Advanced Tour TASK 808 Data Storage As shown above, the PP4300’s memory (referred to as internal memory) can store a modest amount of data – about 200 Kbytes (although the actual memory capacity is 256 Kbytes, overhead cuts the useable data memory space to about 200 Kbytes). Saving Data to Internal Memory If the system is being operated without an optional memory card, configuration data and monitoring data is automatically saved to the PP4300’s internal memory. There is no need to “save” the data in the sense that data must be saved on a PC. The PP4300 automatically writes data to the internal memory as it is accumulated. Optional Memory Card The optional memory card, however, can hold much more data than the internal memory. Although not an absolute requirement, a memory card is recommended for almost all applications. Various memory card capacities are available, see Appendix C. Auto-transfer As data is captured, it is always written directly to the PP4300’s internal memory. If a memory card is included in the configuration, data can be automatically copied from internal memory to the memory card as the internal memory fills. This feature is called Auto-transfer. 39 Page Chapter 6 Advanced Tour TASK 808 Storage Techniques When data is collected over extended periods of time, it may exceed the memory capacity of even the memory card. To address this limitation, data is always written to memory using one of the following user-specified techniques: either Fill and Stop or Overwrite. Fill and Stop This technique works just like it sounds: data is written to internal memory until it is full and then the data storage process shuts down. Using this technique, the oldest data is retained, the collection of data is stopped. Overwrite This technique also works just like it sounds: data is written to internal memory until it is full and then begins to overwrite, starting with the oldest data first. Using this technique, the most recent data is retained, the oldest data is overwritten. The following table summarizes how these memory features work together under four different scenarios: Page 40 Chapter 6 Advanced Tour TASK 808 Memory Feature Table Memory Fill and Stop Overwrite mode? Auto- Enabled Disabled Enabled Disabled transfer? Memory YES N/A YES N/A card? Scenario #1 Scenario #2 Scenario #3 Scenario #4 As PP4300’s PP4300’s As PP4300’s PP4300’s internal internal internal internal R memory fills, memory fills memory fills, memory fills E data is copied and stops. data is and is to the memory copied to the overwritten.

NOTE - the memory card is never overwritten. Now, back to the Advanced Guided Tour… 41 Page Chapter 6 Advanced Tour TASK 808 Memory Functions, Continued The “Memory Functions” screen is the function control menu for both the internal memory and the optional memory card. Jan-17-97 18:34:45 MEMORY FUNCTIONS 1. MEMORY CARD FUNCTIONS 2. SET AUTO-TRANSFER TO MEMORY CARD 3. CLEAR MEMORY 4. SET MEMORY STORAGE MODE 5. RESET TO FACTORY CONFIGURATION EXIT Step 6 Press the 1 key on the numeric keypad to display the Memory Card Functions screen. This screen displays the status of the memory card installed. Use this screen to read and write event and setup data on the memory card and to format the memory card (see Appendix F). Jan-17-97 18:34:45 MEMORY CARD FUNCTIONS CARD SIZE: 1024K CARD FREE SPACE: 10K WRITE PROTECT:OFF MEMORY CARD BATTERY:OK WRITE READ FORMAT CARD CARD CARD EXIT Use the View Data menu shown in Chapter 7 to read the Auto-transfer file. • NOTE: In order to view data stored on a memory card, it must first be read (copied) into internal memory. Reading data from a memory card will erase all data presently in internal memory. Page 42 Chapter 6 Advanced Tour TASK 808 Saving/Reading Data When data is saved manually to the memory card using the WRITE DATA SOFTKey, an event file (.evt) is created. This file consists of all data currently in internal memory. Using the WRITE SETUPS SOFTKey creates a setup file (.set), which contains the instrument configuration. When Auto-transfer is enabled, data is saved automatically to the memory card and is stored in an Auto-transfer file (.mdb). Event files and setup files are retrieved using the Memory Card Functions screen. Auto-transfer files are retrieved using the View Data screen. File Sizes Since the internal memory data storage capacity is 200 Kbytes, files written to memory cards manually will always be 200 Kbyte files (even though the actual amount of data may be less). On the other hand, the size of files created using the Auto-transfer function is limited only by the size of the memory card and typically would be much larger than 200 Kbytes. A procedure has been developed for reading files which were written to the memory card by auto-transfer and which may be several times larger than the 200 Kbyte internal memory. In such cases, only 200 Kbytes can be read into internal memory at a time. Therefore, data is copied from the memory card to internal memory in 200 Kbyte blocks. The user is prompted to enter a start date and time. This becomes the starting point from which the 200 Kbyte block of event data is selected. Press the EXIT SOFTKey to return to the “Memory Functions” screen. Step 7 Press the 2 key on the numeric keypad to toggle between Auto- transfer enabled, Auto-transfer disabled. As could be seen from the Memory Features Table (shown earlier), when a memory card is in use, it is usually wise to enable auto-transfer (scenario #3). NOTE - If the PP4300 is powered ON with a new or freshly formatted memory card installed, and with Auto-transfer enabled, it will appear that much less storage space is available than would be expected. This phenomenon occurs because auto-transfer automatically allocates space. Thus, for example, a two Mbyte card will show only 48K of free space. The actual amount of stored data is shown on the View Data/ “Site Status” screen. 43 Page Chapter 6 Advanced Tour TASK 808 Oct-17-96 18:34:45 AUTO-TRANSFER TO MEMORY CARD AUTO-TRANSFER: ENABLED ENABL/ DISABL EXIT Press the EXIT SOFTKey to return to the “Memory Functions” screen. Step 8 Press the 3 key on the numeric keypad to clear all events stored in the PP4300’s internal memory. NOTE - Perform this operation ONLY if there is no valuable information in internal memory.

Exit from the “Memory Functions” screen and return to the “Setup Menu” screen by pressing the EXIT SOFTKey. 6.1.5 Set Input Configurations From the “Setup Menu” screen, press the 5 key on the numeric keypad to display the “Set Input Configurations” screen. Several very important parameters are available from the “Set Input Configurations” screen: 45 Page Chapter 6 Advanced Tour TASK 808 Oct-17-96 18:34:45 SET INPUT CONFIGURATIONS 1. SET CIRCUIT TYPE 2. SET ACTIVE CHANNELS 3. SET SCALE FACTORS 4. SET SYNC PARAMETERS 5. DEMAND INTERVAL SETTINGS 6. SELECT CURRENT PROBES 7. DEMAND/ENERGY PARAMETER 8. DEMAND AND ENERGY LIMIT EXIT Step 1 Press the 1 key on the numeric keypad to set the circuit type. This screen was previously reviewed in the Easy Start Guided Tour. Exit by pressing the EXIT SOFTKey. Step 2 Press the 2 key on the numeric keypad to display the “Active Channels” screen. Jan-17-97 18:34:45 ACTIVE CHANNELS CHANNEL VOLTS AMPS A ON ON B ON ON C ON ON D LOW ON NEXT VOLTS AMPS CHAN ON/OFF ON/OFF EXIT This screen is used to toggle ON or OFF the status of channels A, B and C. In addition – if you highlight and toggle channel D, you will notice that there are three voltage options for channel D: LOW, HIGH and OFF. The LOW voltage range is from 0.5 to 20.0 Vrms, and is available for channel D hookups, e.g., ground-to-neutral, which may require a much lower range. The HIGH voltage range is the same as ON, i.e., from 10 to 600 Vrms. The “ Scale Factors” screen (shown below ) displays the actual channel D status setting. Page 46 Chapter 6 Advanced Tour TASK 808 NOTE - The “Active Channels” screen controls the channels which are actively collecting data. A very similar screen, the “Channel Selection” screen, was reviewed in the Easy Start Guided Tour. But that screen, however, only filters the data for display on the “Scope Mode” graph. Unlike the options on the “Active Channels” screen, the “Channel Selection” screen has no control over the collection of data. Exit by pressing the EXIT SOFTKey. Step 3 Press the 3 key on the numeric keypad to set the voltage and amperage scale factors for each channel. Jan-17-97 18:34:45 SCALE FACTORS CHAN VOLTS AMPS A 1.0000 1.0000 B 1.0000 1.0000 C 1.0000 1.0000 LOW D 1.0000 1.0000 NEXT ENTER CHAN SCALE EXIT The scale factor for all of the listed optional Dranetz-BMI current probes is automatically factored in behind the scenes and should be entered as 1.0 (unless changed on the secondary of another current transformer). However, The scale factors of any non-Dranetz-BMI current or voltage transformer must be accounted for in making accurate measurements. Because the monitored output current or voltage is frequently stepped down (divided) from the original current or voltage, this ratio must be stepped up (multiplied) by the scale factor when computations are performed. The scale factor is usually marked on the transformer. This value must be entered into the “Set Scale Factors” screen. Refer to the device or the manufacturer’s literature for the scale factor for devices which you may be using. 47 Page Chapter 6 Advanced Tour TASK 808 Scale Factor Calculation - Example Suppose the 5A secondary output current of a 5000A current transformer is being monitored. The scale factor would be calculated as follows: CT Full Scale Input x Dranetz-BMI Probe Scale Factor = Scale Factor CT Full Scale Output 5000 x 1 = Scale Factor of 1000 5 Exit the “Scale Factors” screen by pressing the EXIT SOFTKey. Step 4 Press the 4 key on the numeric pad to set the sync (synchronization) parameters. Sync, i.e., maintaining a constant phase relationship between AC signals, may be either external or internal. When set to external, the PP4300 attempts to sync to an incoming voltage signal. When set to internal, the PP4300 uses the nominal frequency when making measurements. External sync is recommended unless no adequate voltage source is available. Enter a nominal frequency which matches the line frequency so that if the PP4300 loses external sync, it will have a corresponding internal sync. Failure to set this value correctly can result in erroneous data. Page 48 Chapter 6 Advanced Tour TASK 808 Jan-17-97 18:34:45 SYNC PARAMETERS SYNC MODE: EXTERNAL NOMINAL FREQUENCY: 60.0 SELECT ENTER SYNC FREQ EXIT Press the SELECT SYNC SOFTKey to toggle through the sync mode options.

SET START START INTRVL NOW AT EXIT Press the SET INTRVL SOFTKey to change the interval start time and date (watch the screen carefully when selecting this – especially the SOFTKeys -- note that ENTER and BACKSPACE SOFTKeys become operational). This screen is especially significant because it calculates how long it will take to fill the internal memory excluding events other than timed demand interval events. 49 Page Chapter 6 Advanced Tour TASK 808 When finished, press the START NOW SOFTKey to start collecting immediately, or use the START AT SOFTKey to enter a different (and future) start time and date. When finished, the “Set Input Configuration” screen will be displayed. Step 6 Press the 6 key on the numeric keypad to select current probes (this function was already reviewed in the Easy Start Guided Tour). After making selection, exit by pressing the EXIT SOFTKey. Step 7 Press the 7 key on the numeric keypad to set the demand/energy parameter. Jan-17-97 18:34:45 DEMAND/ENERGY PARAMETER PARAMETER: WATTS WATTS VA VARS EXIT Press the WATTS, VA or VARS SOFTKeys to set the demand/energy parameter. Exit by pressing the EXIT SOFTKey. Page 50 Chapter 6 Advanced Tour TASK 808 Step 8 Press the 8 key on the numeric keypad to enable and set demand and energy limits: Jan-17-97 18:34:45 DEMAND/ENERGY LIMITS DEMAND LIMIT : 2229.0 W ENERGY RATE LIMIT : 9300.0 WHR SET SET DISABLE DISABLE DEMAND ENERGY DEMAND ENERGY EXIT Use the SOFTKeys to SET, ENABLE or DISABLE the limits. The consequences of enabling and setting these limits are as follows: Demand limit - At the end of each demand interval, the average demand is compared with this limit. If the demand is greater than this limit, it is treated as an event and is recorded. Energy Rate Limit - The energy rate is computed once every minute. If the rate exceeds this limit, it is treated as an event and is recorded. Exit by pressing the EXIT SOFTKey. Exit from the “Set Input Configurations” screen by pressing the EXIT SOFTKey. Exit from the “Setup Menu” screen and return to the “Scope Mode” screen by pressing the SCOPE MODE SOFTKey.

Demand defined. The demand is the load which is drawn from the source of supply at the receiving terminals, averaged over a suitable and specified interval of time, such as fifteen minutes or a half-hour. Demand is expressed in kilowatts, kilovolt-amperes, amperes, or other suitable units. Note that as demand is measured in watts, etc., and not in watt-hours, etc., it is shown by an indicating and not an integrating device. Measure of the demand. The demand is usually measured in kilowatts; but where power factor is an important item, the reactive kilovolt-amperes and sometimes kilovolt-ampere demand are measured. The demand of an installation is defined as the load which is drawn from the source of supply at the receiving terminals, averaged over a certain period of time. This interval of time usually used is 15 minutes, although in certain cases other intervals are used, such as 5 minutes, 30 minutes, or 60 minutes. It is very seldom that a customer is billed on instantaneous demand, unless the short high peaks may be of such a nature as to interfere with the stability of the system. The principal factor which limits the load which the equipment of a system can carry is temperature. Because this equipment has mass, the final temperature is reached only after an appreciable period of time for a given load. The heating of the equipment does not follow any simple law. In a generator, the armature losses vary as the square of the current, and the field losses vary with the power factor as well as the current. In other parts of the equipment, the heating follows somewhat different laws. In general, it might be said that most of the change in temperature occurs during the first 15 or 30 minutes after the load is applied. 85 Page Appendix D PP 4300 Technical Specs TASK 808 D.1.1 Dimensions Size: 12” Width x 2.5” Depth x 8” Height (30.5 x 6.4 x 20.3 cm) Weight: 4 pounds (8.8 kg) D.1.2 Environmental Operating: 5 to 45 °C (41 to 113 °F) Storage: -20 to 55 °C (-4 to 131 °F) Humidity: 10% to 90% non-condensing D.1.3 System Time Clock Crystal controlled. 1 second resolution.

E.2.2 Available probes Several Dranetz-BMI current probes can be used with the PP4300: models TR2500, TR2510, TR2520, TR2021, TR2019B, TR2022, TR2023. The TR2500, 2510 and 2520 will plug directly into any of the current inputs on the rear panel, the others are used with the Dranetz-BMI model 658 but can be connected to the PP4300 with an adapter cable. Typical current probes are illustrated on the following page. n Refer to Appendix C Optional Accessories for additional information regarding the adapter cable and models TR2500, 2510, 2520. Probe positioning: An arrow marking on the handle is a guide to ensure that you position the probe with the arrow pointing in the direction of current flow to the load when monitoring the line conductor. Correct position of the probe is necessary for correct power measurements, where in-phase voltage and current measurements are necessary. A positive watts reading indicates that the probe is pointed towards the load, and a negative reading indicates that the probe is pointed towards the source. Page 102 Appendix E Connecting Probes TASK 808 E.2.3 Reference to Channel Input Because no reference at the probe end identifies which channel is being monitored, a wire marker kit is supplied as a standard accessory to help in probe/channel identification. This kit provides color-coded channel marker labels to attach to both the probe handle and the plug end of the probe. 103 Page Appendix E Connecting Probes TASK 808 E.2.4 Connection Guidelines Follow these guidelines when making current connections. o Position the probe with the arrow on the handle pointing towards the load. o For greatest accuracy, use a probe that is rated at no more than twice the nominal value you expect to measure. o Measuring currents less than 10% of full scale can lead to erroneous results. E.2.5 Single phase current probe example The following figure shows how to connect a current probe to channel A for current monitoring of a single phase line. The current probe may be connected to the return line if desired to measure the return current when checking for load current leakage, loop current relationships, etc. If measuring the return line, position the probe with the arrow pointing toward the source. The connection shown above is not recommended without a voltage connection to ensure frequency synchronization. If this configuration is used, then an internal frequency reference must be entered.

E.3.3 Voltage and current connections This section contains numerous drawings of both voltage and current probe connections that are required when power measurements are to be made. Voltage: Voltage measurement cables are connected to the individual source or load line and are referenced to the return (common) line voltage measurement cable connection for greatest accuracy. Current: Current probes are connected to each line and positioned to measure currents with reference to the voltage measurement cable. Incorrectly positioned current probes may produce erroneous power measurement. E.3.4 Phasor diagrams Correct phasor diagrams (for resistive loads) are shown for each connection. 107 Page Appendix E Connecting Probes TASK 808 E.3.5 Verifying Voltage and Current Connections Introduction Correct voltage and current connection of single phase, split phase, or polyphase connections can be verified using phasor diagrams. Phasor diagrams are graphic representations that show the magnitude and angular relationship of each phase of a monitored connection. Each connection diagram on the following pages shows the correct voltage and current phasor diagrams (for resistive loads) for that circuit. The PP4300 Phasor diagrams are dynamically updated every 5 seconds. Single phase A single phase voltage or current phasor is displayed as a single line showing a channel reference at 0 degrees and a magnitude relative to its measured value. An arrowhead on the line indicates direction. Split phase Split phase vectors are displayed as dual lines showing channel references and magnitudes and opposite (180 degrees) directions. Three phase Three phase vectors are displayed as three lines, 120 degrees apart in a resistive load (unity power factor). Phase displacement will occur in a reactive load. Page 108 Appendix E Connecting Probes TASK 808 Correct 3-phase voltage phasor connections The voltage phasor display shown below is for a three phase, four wire, wye connection. Correct 3-phase current phasor connections The current phasor display shown below is for a three phase, 4 wire wye connection. 109 Page Appendix E Connecting Probes TASK 808 Incorrect current phasor diagram The following phasor display shows an incorrect current probe connection. The phasor for channel C is 180 degrees out of phase. This can be corrected by reconnecting the probe so that the arrow on the probe handle points toward the load. Single channel phasor diagram The following display shows the voltage and current phasors for channel A. Page 110 Appendix E Connecting Probes TASK 808 NOTE - All phasor diagrams for connections E.4 through E.10 (on the following pages) are drawn assuming balanced, resistive loads. E.4 Single Phase E.4.1 Introduction When making voltage connections to a single phase circuit use channel A differential inputs as shown below. Connect the current probe with the arrow on the handle pointing toward the load or an erroneous power reading will result. E.4.2 Connection diagram E.4.3 Single Phase Phasor Diagrams 111 Page Appendix E Connecting Probes TASK 808 E.5 Split Phase E.5.1 Introduction When making split phase measurements use both channels A and B for voltage and current connections. The neutral is chosen as the reference for measurement purposes. E.5.2 Connection diagram E.5.3 Split Phase Phasor Diagrams Page 112 Appendix E Connecting Probes TASK 808 E.6 Open Leg Delta E.6.1 Introduction The figure below shows the open leg delta with phase A-C connected to channel A and phase B-C connected to channel B. Current probes are connected to channels A and B. For ABC channel values to be correct, set the Task 808’s input configuration circuit type to Split Phase.

The neutral is connected to common and is the reference for the three channels. E.7.2 Connection diagram 115 Page Appendix E Connecting Probes TASK 808 E.7.3 Four Wire Wye Phasor Diagrams Page 116 Appendix E Connecting Probes TASK 808 E.8 High-Leg Delta E.8.1 Introduction In the high-leg delta connection, also called delta with center tap or red- legged delta, the 4-wire delta connected 120/240V source is connected with one phase connected to ground at mid-point. This phase provides 120V at phases A and C to ground. Phase C is designated the high-leg connection and is measured at 208V (120V x 1.73 = 208V) to ground. The National Electrical Code (1996 NEC 215-8) identifies the high-leg phase as the orange colored line. For ABC channel values to be correct, set the Task 808’s input configuration circuit type to 3 phase wye. E.8.2 Connection diagram 117 Page Appendix E Connecting Probes TASK 808 E.8.3 High Leg Delta Phasor Diagrams Page 118 Appendix E Connecting Probes TASK 808 E.9 Floating or Grounded Delta E.9.1 Introduction In this power connection, the PP4300 uses voltage channels A, B, and C as differential inputs with channel A using source voltage A-B, channel B using B-C, and channel C using C-A as the reference. Current probes are connected to channels A, B, and C. For the grounded delta, channel C should be connected to the grounded leg. If only two channels are used (only two CTs available), then the voltage B-C in channel B and C-A in channel A should be used, along with the CTs on channels A and B. E.9.2 Connection diagram 119 Page Appendix E Connecting Probes TASK 808 E.9.3 Floating or Grounded Delta Phasor Diagrams Page 120 Appendix E Connecting Probes TASK 808 E.10 Two-and-a-half Element E.10.1 Introduction For older type 2 ½ element (stator) metering circuits, the two voltage channels A and C are used, along with the three current channels as shown below. Voltage B is not connected and is calculated by the Task 808. E.10.2 Connection Diagram 121 Page Appendix E Connecting Probes TASK 808 E.10.3 Two-and-a-half Element Phasor Diagrams Explanation of values displayed The 2 1/2 element configuration is used to replicate wattmeters where there are two voltages and three currents. The wattmeter may have one of two internal configurations. One type uses two stators with two current coils, plus an additional ‘Z-coil’ current coil. The other type uses two stators with two current coils, where the third current circuit is run through both current coils. “The assumption is made in this meter that the phasor sum of the two line- to-neutral voltages is exactly equal and opposite in phase to the third line- to-neutral voltage. When this condition exists, the metering is correct regardless of current or power-factor unbalance. The assumption, however, is correct only if the phase voltages are balanced. If the voltages are not balanced, metering errors are present, the magnitude of which depend upon the degree of voltage unbalance.”1 To calculate the percent error, refer to the Handbook for Electricity Metering, page 155, figure 7- 24 (Error Curves).2 In the TASK808, the “missing” voltage phase is phase ‘B’. Only the current is directly measured. Since the remaining phase ‘B’ values are derived and not measured directly, these values are displayed as ‘XXXX’. 1, 2 Edison Electric Institute, Handbook for Electricity Metering, 9th ed. (Washington, D.C.: EEI, 1992), 154-55. Page 122 Appendix E Connecting Probes TASK 808 E.11 Connecting to PTs and CTs Before attempting to connect to the secondary of PTs (potential or voltage transformers) and CTs (current transformers), the user should have a thorough understanding of how the primary and secondary of these devices are connected. There are many different configurations used in electric utility and industrial facilities, which vary depending on their intended use, such as inputs to relays or revenue metering. Variations include both the number of PTs and CTs (3 and 3, 2 and 3, 2 and 2, etc.), as well as the wiring configurations (3 wire wye, 3 wire floating delta, grounded delta, etc.). The following guidelines can be used along with the instructions supplied by the instrumentation manufacturer to cover several frequently encountered circumstances: If the type of circuit being monitored Then the most likely circuit is: configuration for the described application is: Three phase delta with two PTs Open leg delta having a common ground Three phase delta with three PTs or Floating delta three phase wye without a neutral connection Three phase wye with a neutral Four wire wye 2 ½ element metering configuration 2 ½ element • WARNING: Refer to the circuit connection schematics shown in this appendix and to the PT manufacturer’s information for assistance in determining the proper connections to a PT. • ADVERTENCIA: Consulte el esquema de conexiones de circuitos que aparece en este apéndice, y la información sobre TP (transformador potencial) del fabricante, para obtener ayuda para determinar las conexiones correspondientes a un TP. • AVERTISSEMENT: Se reporter aux schémas de connexion des circuits présentés dans cette annexe et aux informations fournies par le fabricant du transformateur de tension (PT) pour toute assistance concernant les connexions correctes à un transformateur de tension. 123 Page Appendix E Connecting Probes TASK 808 • WARNUNG: Die in diesem Anhang gezeigten Skizzen von Schaltverbindungen und die Herstellerinformationen zum Spannungsteilertransformator helfen Ihnen, die richtigen Anschlüsse an einen Spannungsteilertransformator festzulegen. E.12 Connecting to a Potential Transformer (PT) • NOTE: Potential transformers are not manufactured by Dranetz-BMI and are discussed here for informational purposes only. E.12.1 Definition A potential transformer (PT), also referred to as a voltage instrument transformer, provides the necessary step-down ratio to reduce the high voltage of circuits above 600 Vrms to a level for safe measurement. A PT also provides isolation and proper connections for instrument attachment. E.12.2 Connections PTs are usually fixed in position and require that the voltage measurement cable(s) be connected to their terminal connections. • WARNING: Refer to the manufacturer's instructions, related to the PT, for exact information for probe connection for voltage monitoring. Do not exceed 600 Vrms input to the PP4300 voltage inputs. • ADVERTENCIA: Consulte las instrucciones del fabricante referentes a TP (transformador potencial), para la información exacta de la conexión de sonda a fin de monitorear el voltaje. No supere la entrada de 600 Vrms a las entradas de voltaje de PP4300. • AVERTISSEMENT: Se reporter aux instructions du fabricant relatives au transformateur de tension (Potential Transformer - PT) pour obtenir les renseignements exacts sur la connexion de sonde utilisée pour la surveillance du courant. Ne pas dé passer l'entrée de tension efficace de 600 RMS dans les entr ées de tension de PP4300 volts. • WARNUNG: Genaue Informationen zur Meáfühlerverbindung fü r die Spannungsüberwachung entnehmen Sie bitte den Anleitungen des Herstellers (siehe Page 124 Appendix E Connecting Probes TASK 808 Spannungsteilertransformator). Die Eingangsspannung von 600 V (Effektivwert) in die PP4300 Spannungseingänge sollte nicht überschritten werden. E.12.3 Procedure Follow these steps to connect voltage measurement cables to a potential transformer. Step Action 1 Turn OFF power to the PT. 2 Connect the colored voltage measurement cables to the channel inputs on the PP4300's rear panel. 3 Connect the colored voltage measurement cables to the PT's connections in accordance with the manufacturer's instructions. 4 Turn ON power to the PT. E.12.4 Scale factor The scale factor of the PT must be accounted for in making accurate voltage measurements. Because the monitored output voltage of the PT is stepped-down (divided) from the original voltage, this ratio must be stepped-up (multiplied) by the PP4300 when voltage computations are performed. The PT scale factor is usually imprinted on the PT assembly and is entered into the PP4300 on the “Scale Factors” screen. Refer to the PT manufacturer's literature for the scale factor for the device you are using. See Scale Factor Calculation Example in Chapter 6. E.13 Connecting to a Current Transformer (CT) • NOTE: Current transformers are not manufactured by Dranetz-BMI and are discussed here for informational purposes only. E.13.1 Safety Precautions The following safety precautions apply to current transformer (CT) connections. o Never energize a CT with the secondary open. o Never disconnect the secondary of a CT with primary energized. 125 Page Appendix E Connecting Probes TASK 808 Medidas de seguridad Las medidas de seguridad siguientes corresponden a conexiones de transformadores eléctricos (CT). o Nunca deberá poner bajo tensión un CT con el transformador secundario abierto. o Nunca deberá desconectar el transformador secundario de un transformador eléctrico si el transformador primario está bajo tensión. Mesures de sécurité Les mesures de sécurité suivantes s’appliquent aux connexions de transformateurs de courant. o Un jamais mettre un transformateur sous tension lorsque la bobine secondaire est ouverte. o Ne jamais déconnecter la bobine secondaire d’un transformateur lorsque la bobine primaire est sous tension.

No exceda las capacidades nominales del fabricante. • AVERTISSEMENT: Se reporter aux instructions du fabricant relatives au transformateur de courant (Current Transformer - CT) pour obtenir les renseignements exacts sur les connexions Page 126 Appendix E Connecting Probes TASK 808 utilisées pour la surveillance du courant. Ne pas dépasser la puissance recommandée par le fabricant. • WARNUNG: Genaue Informationen zu Verbindungen für die Stromüberwachung entnehmen Sie bitte den Anleitungen des Herstellers (siehe Stromumwandler). Die Grenzwerte des Herstellers sollten nicht überschritten werden. E.13.2 Description Current transformers, also known as instrument transformers, reduce high level currents to low level currents so they can be safely monitored. These devices are similar to PTs used for voltage measurements in that both reduce values for safe measurement. The reduction, or step-down ratio, is stated as a scale factor that is used by the PP4300 to step-up the measured value to its original value. E.13.3 Types of CTs There are single-phase CTs and polyphase CTs dependent on the source transformer used. Current reduction ratios vary widely and are also dependent on the source transformer used. Rating plates attached to the CT provide information about the ratio and current limitations. E.14 Connecting to an Isolated Current Transformer (ISO) E.14.1 Introduction Low current monitoring devices made by Dranetz-BMI are called isolated current transformers or ISO boxes. The Dranetz-BMI ISO box has a 5 A current range. See Set Input Configurations in Chapter 6 for information on scale factors. See Appendix C for ISO box description. E.14.2 Safety Precautions The following safety precautions apply to ISO box connections in addition to those safety precautions stated at the beginning of this Appendix. Never energize an ISO box with the secondary open. Never disconnect the secondary of an ISO box with primary energized. 127 Page Appendix E Connecting Probes TASK 808 Medidas de seguridad Las medidas de seguridad siguientes, además de aquellas que aparecen al principio de este apéndice, corresponden a conexiones de caja ISO. o Nunca deberá ponerse bajo tensión una caja ISO con el transformador secundario abierto. o Nunca deberá desconectarse el transformador secundario de una caja ISO mientras esté bajo tensión el transformador primario. Mesures de sécurité Les mesures de sécurité suivantes s’appliquent aux connexions de boîte ISO en plus des mesures de sécurité présentées au début de cette annexe. o Ne jamais mettre une boîte ISO sous tension lorsque la bobine secondaire est ouverte. o Ne jamais déconnecter la bobine secondaire d’une boîte ISO lorsque la bobine primaire est sous tension. Sicherheitsvorkehrungen Die folgenden Sicherheitsvorkehrungen für ISO-Dosenanschlüsse gelten zusätzlich zu den Sicherheitsvorkehrungen, die zu Beginn dieses Anhangs genannt wurden. o Führen Sie einer ISO-Dose niemals Strom zu, wenn die Niederspannungsseite geöffnet ist. o Lösen Sie niemals die Verbindung der Niederspannungsseite einer ISO-Dose, wenn die Oberspannungsseite unter Strom steht. • WARNING: Physical injury or equipment damage could result if ISO boxes are improperly connected. Do not connect an ISO box between two conductors which are at different voltage potentials. • ADVERTENCIA: Podrían producirse lesiones físicas o daños al equipo si se conectan indebidamente las cajas del transformador aislado de corriente (ISO). No conecte una caja del ISO entre dos conductores que tengan distintos potenciales de voltaje. Page 128 Appendix E Connecting Probes TASK 808 • AVERTISSEMENT: Une mauvaise connexion des transformateurs d'intensité isolés (ISO) peut provoquer des blessures corporelles ou des dégâts matériels. Ne pas relier les transformateurs ISO entre deux conducteurs de tensions diffé rentes. • WARNUNG: Falsch angeschlossene ISO-Kästen (Isolierte Stromumwandler) können zu körperlichen Verletzungen oder Geräteschäden fuehren. Schliessen Sie einen ISO-Kasten nicht zwischen zwei Leiter mit unterschiedlichem Spannungspotential. E.14.3 Connections to ISO box The ISO box has terminal posts labeled X1 and X2 that are connected in series only with an ac current source. In normal connections, where phasing of current and voltages are important for power measurements, the X1 terminal is connected towards the source input line. When connecting to CTs, the X1 terminal is normally connected to the H1 terminal of the device for correct reference phasing. Where power measurements or voltage/current phase relationships are not important, the X1 and X2 terminals may be connected in series with the output device in any line (hot or return) or in any relationship of X1/X2. E.14.4 Applications ISO boxes can be used in a number of ways. These methods include: connecting them to the secondary of CTs for metering by the PP4300. inserting them in series with the load current to measure low current values. connecting them to a non-Dranetz-BMI clamp-on current transformer and using that CT to monitor current with the PP4300. E.14.5 ISO box connection to a current transformer The figure below shows an ISO box connected from any current channel input to a permanently installed CT. The connection shown is made in the load return line for current monitoring only. Polarities of the ISO box and CT are kept in-phase by matching markings of X1 to H1. Scale factors of both devices must be multiplied together to get the resultant scale factor. 129 Page Appendix E Connecting Probes TASK 808 See Set Input Configurations in Chapter 6 for more information about scale factors. • CAUTION: DO NOT exceed current limits of the ISO box. • PRECAUCION: NO exceda los límites de corriente de la caja del ISO. • ATTENTION: NE PAS dépasser les limites d'intensité du transformateur ISO. • VORSICHT: Die aktuellen Grenzwerte für den ISO-Kasten sollten NICHT überschritten werden. to adapter cable Page 130 Appendix F Memory Card Functions TASK 808 Appendix F Memory Card Functions F.1 Memory Card Battery Replacement F.1.1 Introduction Replacement of the 3-volt lithium battery in the memory card is needed when the battery message in the “Memory Card Function” screen states the battery is depleted.
