The meters use direct connections to each phase of the voltage, and use current transformers to monitor each phase of the current. Information on energy use, demand, power factor, line frequency and more are derived from the voltage and current inputs. The communications interface to the meters is an RS-485 serial connection that uses the Siemens P1 FLN protocol for sending commands and retrieving data. An APOGEE Building Management and Control System is usually connected to the MD-P1 or MDP1D Power Meter. This APOGEE system unit provides data recording and trend logging plus a human interface or display. Up to 20 MD-P1 or MD-P1D Power Meters may be connected to a single P1 network for monitoring and recording power usage at multiple locations within a single site. The MD-P1D Meter, with an integral 2-line × 16 LCD display provides visual feedback of volts, amps, and Kw, (see Appendix C).

Completing the Wiring Connections - RS-485, Voltage Leads and CTs Mechanically secure FLN cable where it enters electrical utility panel. WARNING The FLN cable within electric panels and switchgear should be jacketed, shielded, twisted triad wire BELDEN 1121A. The jacket insulation rating should be 600V. DO NOT connect FLN cable to field panel yet. WARNING At this time, DO NOT connect the FLN cable to the FLN trunk. Doing so may damage FLN devices or cause personal injury. 1. Remove the black RS-485 connector from the MD-P1 or MD-P1D Power Meter and wire the FLN cable to the RS-485 connector. Connect positive (+), and negative (-) wires to the FLN connector using the daisy-chain method (see Figure 6). Keep length of exposed wire to a minimum. 2. Connect the COMMON wire to the RS-485 connector (S) terminal (see Figure 6). 3. Tape back one of the FLN cable shields and connect the other shield to the Utility Panel Ground. 4. If the MD-P1 or MD-P1D is the last FLN device, install the end of line terminator on the positive (+) and negative (-) terminals. See APOGEE Wiring Guidelines for Field Panels and Equipment Controllers (125-3002) for additional information. 5. Tape or shrink wrap all FLN wire terminations and insulate any other exposed FLN wiring. Ensure that insulation complies with local and national electrical codes. 14 Siemens Industry, Inc. 125-201 2014-09-19 Installation Connecting the MD-P1 and MD-P1D Power Meters 6. Plug the terminal block back into the MD-P1 or MD-P1D Power Meter and mechanically secure the FLN wire terminations to the power meter to prevent accidental removal. Figure 6: Connecting and Insulating FLN Cable on MD-P1/D FLN Connector. WARNING Carefully insulate all FLN lines, including shield, to prevent accidental contact to high voltage conductors. After wiring FLN cable, remove all scraps of wire or foil shield from electrical utility panel. 7. Energize the MD-P1 or MD-P1D Power Meter. It is powered through the red power connector (see wiring connections in Figure 3). 8. Verify proper power meter operation. For normal operation, the RS-485 LED blinks. 9. Close the electric equipment housing. 10. Using a voltmeter, check for high voltage. There should be no significant voltage (no more than 5V AC or DC) from either FLN leg to ground. If voltage is higher than 5V, check for incorrect wiring. WARNING To avoid personal injury or damage to FLN trunk devices, verify no significant voltage (no more than 5V) exists on the FLN. The MD-P1 and MD-P1D Power Meters are designed to be located inside high voltage switchgear. They measure electrical use, and connect directly to the FLN. 11. Insert the CT wires into the green connector/s. 15 Siemens Industry, Inc. 125-201 2014-09-19 Installation Connecting the MD-P1 and MD-P1D Power Meters Figure 7: Wiring Connections. 12. Attach the CTs on the power meter's connections labeled CT 1, CT 2 and CT 3. 13. Place the CTs on the phase wires of the load to be monitored and corresponding to the phase of the voltage leads. The CT labeled CT 1 must be placed on L1 phase voltage wire, CT 2 must be on the L2 voltage and CT 3 on the L3 voltage. See Checking Phases for information about the CT LEDs and verifying the CT installation. When using the MD-P1 or MD-P1D Model Power Meter with Rogowski Coils (or CTs), unused CT input(s) should be shorted with a jumper wire if all three coils are not connected. An unconnected CT input may not show "zero" current due to stray pickup on the open input. WARNING USE ONLY SHUNTED CURRENT TRANSFORMERS (CTs). DO NOT USE 5A SECONDARY CTs OR UNSHUNTED CTs. Do not use other CTs. Only use shunted CTs with a 333 mV maximum output. Serious shock hazard and meter damage can occur if unshunted CTs are used Use only the following Siemens Industry CTs that are UL listed/Recognized and have been evaluated to IEC 61010-1. See Figure 7. 16 Siemens Industry, Inc. 125-201 2014-09-19 Installation Setting the P1 Address 14. Connect electrical power to the power meter's red power connection plugs using 14 AWG THHN (or equivalent) wires, after a building-installed, dedicated circuit disconnect breaker, as close as possible to the breaker. Mark the breaker as the disconnect for the meter. See Wiring Diagrams for specifics of the wiring connections. Follow local electrical codes during this installation. CAUTION Do not strap or mount an MD-P1 or MD-P1D Power Meter less than two inches from current carrying conductors. The magnetic field around the conductors may affect the electronics in the meter. The MD-P1 and MD-P1D Power Meters have an internal non-user replaceable 0.5 Amp internal fuse protection. WARNING Do not exceed 600 Vac Phase-to-Phase CATIII. The MD-P1 and MD-P1D Power Meters are rated for measurement category III. These measurements are performed in the building installation. Examples are: measurements on distribution boards, circuit breakers, wiring including cables, busbars, junction boxes, switches, socket outlets in a fixed installation, and equipment for industrial use. Other equipment could include stationary meters with a permanent connection to the fixed installation. Setting the P1 Address The MD-P1 and MD-P1D Power Meters communicate over an RS-485 serial communication network using Siemens P1-FLN protocol ONLY. These meters are designed to operate at a fixed 4800 baud rate. To communicate on the Siemens APOGEE BMS network, the meter must have a specific network address. The P1 network address switches are located on the front of the meters (see Figure 8). The network address for the device is manually set using these two rotary switches; noting the most significant bit (MSB) and least significant bit (LSB) markings. These network addresses must be entered in hexadecimal format, not decimal format (see Appendix A - Decimal to Hexadecimal Conversion Table). 17 Siemens Industry, Inc. 125-201 2014-09-19 Installation Setting the P1 Address Figure 8: Address Switches Location.

When 80 to 600 Vac or Vdc is placed across the L1 and L2 wires, the three phasing LEDs begin to flash in sequence. For accurate measurements, the neutral conductor must be installed. MD-P1 and MD-P1D Power Meters Single-Phase Connections The MD-P1 and MD-P1D Power Meters can be used to monitor single-phase loads. There are several guidelines to keep in mind about this type of connection: 1. The power meter is powered from a potential between L1 and L2. This can be phase-to-phase (230V) or phase-to-neutral (115V). With a single-phase 230V panel, the L1 and L2 voltage leads are connected between the L1 and L2 voltage sources. With a 115V circuit, the L1 voltage lead is connected to the L1 “hot lead,” and the L2 voltage lead is connected to neutral. 2. Each CT must be paired with the correct voltage source. The current and voltage must be in-phase for accurate measurements. For instance, CT 1 would monitor branch circuit supplied by voltage source L1, and so on. 3. The neutral must be connected because MD-P1 and MD-P1D Power Meters use line-to-neutral measurements for all calculations. Typical 230V Single-Phase Panel Setup Provide wiring from the red terminal block to the panel: L1 Terminal to Voltage L1 (black) L2 Terminal to Voltage L2 (red) White Neutral voltage lead to Neutral. CT1 will monitor L1 loads and CT2 will monitor L2 loads. Based on the above guidelines, CT3 can be used if the blue L3 voltage lead is connected to either L1 or L2. If voltage leads L3 and CT3 are in-phase, the MD-P1 and MD-P1D Power Meters will provide correct kW readings. If the blue L3 voltage lead is connected to the L2 voltage source, then CT3 can monitor any L2 branch circuit. Or, if the blue L3 voltage lead is connected to the L1 voltage source, then CT3 can monitor any L1 branch circuit. Typical 115V Single-Phase Panel Setup Provide wiring from the red terminal block to the panel: L1 Terminal to Voltage L1 (black) L2 Terminal to Voltage L2 (red) White N voltage lead to neutral. The power supply is across the black (L1) and the red (L2) lead; therefore, the red (L2) lead must also be connected to the neutral line. CT1 will monitor the L1 load. CT3 can be used if the blue L3 voltage lead is connected to L1. CT3 could then monitor any L1 branch circuit. 19 Siemens Industry, Inc. 125-201 2014-09-19 Installation Checking Phases System Values System values are the sum of L1 + L2 + L3 measurements. System values may not be meaningful since two different devices or loads can be monitored by a single MD-P1 or MD-P1D Power Meter element. When paired with the correct voltage phase, each CT provides individual kW/kWh readings for that CT channel. Checking Phases The CT phase-checking LEDs are a unique feature of the MD-P1 and MD-P1D Power Meters that simplify installation by ensuring proper CT-to-phase installation and avoiding faulty data collection. The power meters automatically adjust for CT orientation—reducing set-up time and nearly eliminating installation errors. Verifying the MD-P1 and MD-P1D Power Meters Setup Using the LEDs The MD-P1 and MD-P1D Power Meter have three bi-color LEDs for each element. These LEDs provide the following information: All LEDs are green — the system power factor is greater than 0.55 and the CTs are properly placed on the corresponding voltage phases. Any one LED is red — there is a phasing connection error. Two LEDs are red and one is green — two CTs are reversed. All three LEDs are red — all CTs are incorrectly connected. If the total system power factor is less than 0.55, the LEDs are red even if connected properly. This situation is rare but can occur if, for example, the load to be monitored is a lightly loaded electric motor where it is common for the power factor to be less than 0.55 and the corresponding LEDs will be red. 20 Siemens Industry, Inc. 125-201 2014-09-19 Installation MD-P1 and MD-P1D Power Meters Wiring Diagrams The following table describes error conditions and the appropriate correction: Table 3: LED Error Resolution. CT1 CT2 CT3 Error Description Correction Green Green Green Setup is correct and the system Connect the CTs. power factor is greater than 0.55, or all CTs are disconnected. Red Red Red All CTs are incorrectly connected, -orthe system power factor is less than 0.55. Rotate the CT connections by one position by moving CT1 to CT2, CT2 to CT3, and CT3 to CT1, until all LEDs are green. The system power factor is less than 0.55, but the CTs are connected properly indicating a light load. Green Red Red CT2 and CT3 are reversed. Switch the position of the CTs flashing red. Red Red Green CT1 and CT2 are reversed. Switch the position of the CTs flashing red. Red Green Green CT1 is swapped with either CT2 or CT3. Green Red Green CT2 is swapped with either CT1 or CT3. Switch CT1 with CT2, or switch CT1 with CT3. Switch CT2 with CT1, or switch CT2 with CT3. Green Green Red CT3 is swapped with either CT1 or CT2. Switch CT3 with CT1, or switch CT3 with CT2. Red CT1 and CT3 are reversed Switch the position of the CTs flashing red. Green Red MD-P1 and MD-P1D Power Meters Wiring Diagrams The MD-P1 and MD-P1D Power Meters can be wired using any one of the following five common wiring setups. These diagrams will assist you in properly connecting your power meter for the setup desired. NOTE: All wire colors are U.S. Standard, and differ from Canadian standards. For Canadian installations, reverse the red and black wires (L1 = Red, L2 = Black). WARNING DO NOT EXCEED 600 Vac PHASE-TO-PHASE CAT III.

ViewPoint Service Software Tool Functionality The ViewPoint Service software is designed to operate on a laptop computer and interface to the MD-P1 or MD-P1D Power Meters through a USB cable connection. ViewPoint software is compatible with Windows® 7 (32- or 64-bit), Vista (32- or 64-bit), XP or 2000. When ViewPoint is connected to the power meter using a USB cable, power is provided to operate the meter from the USB port. No additional power wiring is needed for this setup and service mode. The service software tool will support a few commonly used service functions such as: Upload MD-P1 and MD-P1D Power Meter settings into ViewPoint for viewing within the service tool. Inspect the meter name, serial number and firmware revision. Inspect Current Transformer (CT) values and parameters. Inspect key real time measurement values (only if connected to load). Perform firmware upgrades for MD-P1 and MD-P1D Power Meters. Obtaining and Installing ViewPoint Software The ViewPoint software is free to MD-P1 an MD-P1D Power Meter users. To download and install the software: 1. Start Internet Explorer and navigate to http://www.dentinstruments.com/siemens/ 2. Log in with User: siemens, password: mdpowermeter. 3. Click the <ViewPointInstaller_3> link. 4. Choose Save, and save the file to the location of your choice. 5. Open the file you saved from Step 4. 6. When asked if you want to run the software, click Run. 7. Click Install. (NOTE: A USB driver is installed when you install the ViewPoint software). 8. Check or uncheck Run Viewpoint, Show Readme, or Create Desktop Shortcut as desired. 9. Click Finish. Connecting and Communicating via a USB Cable It is recommended to use a Type AB USB cable between a personal computer and a MD-P1 or MD-P1D Power Meter to set up the meter. The USB cable will also power the meter when connected to a computer. When using a USB cable with a computer, each USB port on the computer generates a unique comm port in the ViewPoint software, such as Com3 or Com4 (see Figure 3.) 40 Siemens Industry, Inc. 125-201 2014-09-19 Appendices Appendix D - Monitoring and Servicing the MD-P1 and MD-P1D Model Power Meters Commercially Available Examples: CablesToGo UPC 757120281023, Grainger 5XFV4, Best Buy SKU 9457928 A USB driver is installed when you install the ViewPoint software. ViewPoint communicates with the MD-P1 or MD-P1D Power Meter through a USB connection, using Modbus protocol in the service software communication with the meter. The USB connector on the meter can be used to power the unit during configuration. Initial Meter Setup Start ViewPoint software on your computer. Connect one end of the USB AB cable to your computer’s USB port and one end to the MD-P1 or MD-P1D Power Meter’s USB port on the side of the device (see Figure 3).

CONSUMPTN LO (Point 8) and CONSUMPTN HI (Point 9) are accumulators that totalize kWh. The sum of CONSUMPTN LO and CONSUMPTN HI provides the total accumulated kWh for all three phases. These points are always increasing and cannot be reset or commanded to zero. Calculating Total Consumption Example Conceptually, total consumption for any time period is the difference between the reading taken at the start of the time period and the reading taken at the end of the time period. Use the following calculation technique to retain accuracy for calculating total consumption. In this method, the difference (that is, end – start) for accumulator points is taken before summation of the total consumption. (HILAST – HISTART) + (LOLAST – LOSTART) = CONSUMPTIONPERIOD January 99 (2620 – 1310) + (300 – 160) = 1310 + 140 = 1450 February 99 (3920 – 2620) + (100 – 300) = 1310 + (–200) = 1110 The following PPCL reads the MD-P1 and MD-P2 accumulators at the start of the specified time period (for example, month, week, and day) and stores them in virtual analog points. To calculate the consumption for a specified time period, a test is conducted where the most recent (that is, last) accumulator value is tested against the low accumulator reading taken at the start of the time period. The resulting calculated value can be displayed on an Insight graphic to assist building operators in monitoring the energy consumption in their facilities. 00010 C ENERGY MANAGEMENT PROGRAM TO CALCULATE MONTHLY, WEEKLY AND DAILY USAGE 00012 C 00030 C THIS SOFTWAWRE IS OWNED AND MAINTAINED BY SIEMENS BUILDING TECHNOLOGIES, INC. 00032 C ALL RIGHTS RESERVED.

The slope and intercepts of %X%CMH and %X%CML are the same as accumulator points (%Z%, %Y%). 57 Siemens Industry, Inc. 125-201 2014-09-19 Appendices Appendix F - Measuring Consumption (kWh), Demand, and Other Applications 2. The slope (that is, resolution) for monthly readings should be determined by identifying the maximum billed consumption or using the following equations (assume PF = 1.0): kWref = (CTref. Amps × Voltsref)/1000 for 1-Phase Power kWref = (CTref. Amps × Voltsref × SQRT(3) × PF)/1000 for 3-Phase Power kWh = kWref * 24 hours/day × 31 Days for kWh per Month kWh = kWref * 24 hours/day × 7 Days for kWh per Week For firmware revisions earlier than 2.0, do not use the $LOC resident point for intermediate calculations; the maximum value of the $LOC resident point is 32,767. Maximum Physical Unit (V2) Slope (Resolution) Intercept (V1) 32,766.00 1 0 327,660.00 10 0 163.83 0.05 0 1638.30 0.5 0 163,830 5 0 1,638,300 50 0 32,766.00 1 0 Measuring and Calculating Demand (kW) DEMAND represents the instantaneous 3-phase total demand (kW) and functions as a logical analog input. In applications where the demand fluctuates, increase the COV parameter for DEMAND to reduce COV traffic. If the power meter is reading whole building kW, the largest number of COVs occurs when the building transitions from unoccupied to occupied status. For example, using a 300A power meter with a COV limit of 0.064 results in changes of values being observed for every change greater than 0.064 kW (such as every time a 1.0 HP motor, one 100W light bulb, or a personal computer is energized). In general, select the COV for the kW based on the range of the CT. For example, if a 1% COV is needed for a 300 Amp service (300 Amps × Sqrt (3) × 480V/1000 = 249.6 kW ), select a COV of the slope × 20 (provides a COV every 0.064 slope × 20 kW = 1.28 kW). Unless a very high resolution is required, a COV limit of slope × 20 is adequate for most applications. 58 Siemens Industry, Inc. 125-201 2014-09-19 Appendices Appendix F - Measuring Consumption (kWh), Demand, and Other Applications The following table lists kW loads for various motor horsepower ratings: Horsepower kW Horsepower kW 1 0.746 10 7.46 2 1.49 25 18.86 5 3.73 50 37.3 Trending Data If scheduling trend data at the Insight workstation, schedule data collection at regular intervals. Size the field panel trend definition appropriately to prevent trend data from being lost due to roll over. Select the number of samples based on field panel memory and network traffic limitations. It is possible to upload trend data to the workstation using the full trend buffer option or by a scheduled collection time. Collecting Energy Data Many methods can be used to collect data for energy monitoring, reporting, and controlling applications. These methods vary based on intended application, desired accuracy, and field panel memory requirements. The best tradeoff between accuracy and field panel memory requirements is to trend the kWh values every 15 minutes (trend both CONSUMPTN LO and CONSUMPTN HI points). Use this data to calculate total consumption for various time-of-use periods and also to calculate the average demand over a 15-minute period. In this case, DEMAND is used for only real-time load monitoring applications (graphics, alarming, and so on) and does not need to be trended. Applications requiring greater accuracy for demand billing or allocation purposes can collect peak demand calculations with timestamps using the rolling or fixed demand methods. In projects where field panels have severe memory limitations, the 15-minute interval can be extended to 30 or 60 minutes with generally acceptable results. Peak Demand Limiting Electric utilities base their charges to commercial users on a combination of total electricity used during the billing period (known as consumption, kWh and the peak electrical demand required to meet the need of the facility (known as demand, kW). The utility determines the demand charge of a facility by continually measuring electricity usage for successive short time intervals (usually 15 minutes). The highest demand (average kW) during one of these intervals becomes the basis for the demand charges. Since 40% or less of an electric bill can be based on demand charge, it is beneficial to limit the peak electrical demand of the facility. The following PPCL can be used for peak demand limiting applications: 00010 C ELECTRIC SUBMETER 00012 C THE SYSTEM WILL BE DDC CONTROLLED USING ELECTRIC ACTUATION. 00014 C NOTICE: ALL ACTUATORS ARE SET UP IN THE PROGRAM TO WORK AS 0% - 100% 00016 C 59 Siemens Industry, Inc. 125-201 2014-09-19 Appendices Appendix F - Measuring Consumption (kWh), Demand, and Other Applications 00018 C PROGRAM WARRANTY 00020 C \WHAT ARE YOUR INITIALS ?

The summation of power meter accumulator (HI and LO) points should not be used for peak demand limiting applications due to summation round-off error in analog point. You can use the power meter in the APOGEE Peak Demand Limiting (PDL) Application to gain this benefit. For more information on the PDL application, see the APOGEE Field Panel User’s Manual (125-3000). Data Reliability Many power meter/field panel applications require “high data reliability”. This means that trend data collection must be configured to reduce the risk of data loss. To reduce the risk of data loss, schedule trend data collection for regular intervals (for example, every two hours) or use the Trend Buffer Full option to upload trend data to the Insight workstation. To facilitate long-term data collection, schedule trend data conversions daily at the Insight workstation in order to store trend data in the .CSV file format on hard disk. At a later date, the .CSV files can be imported into a report application to develop load profiles, cost allocation, or tenant billing reports. Power Failure On power failure, the power meter retains the last observed kWh value in nonvolatile memory. All other values are instantaneous in nature and not stored during power failure. 62 Siemens Industry, Inc. 125-201 2014-09-19 Frequently Asked Questions - FAQs Glossary Frequently Asked Questions - FAQs One (or more) of the phase verification LEDs is red. What does this mean? Any number of red lights indicates the MD-P1 or MD-P1D Power Meter are wired incorrectly. Review the table in the Phase Verification section of this manual for a description of the indicator lights. How are the MD-P1 and MD-P1D Power Meters powered? The MD-P1 and MD-P1D Power Meters are line-powered. An internal power supply attached between L1 and L2 provides power to the units. Power lines are internally fused. Can the MD-P1 and MD-P1D Power Meters be used to monitor single-phase loads? The MD-P1 and MD-P1D Power Meters can be used to monitor single-phase loads. See the Installation section for detailed setup information. How many MD-P1 or MD-P1D Power Meters can be connected together? Up to 20 MD-P1 or MD-P1D Power Meters can be connected together on a P1 FLN network. How is hexadecimal (HEX) to decimal converted? Use the Decimal to Hexadecimal Conversion table in Appendix A of this manual. Meter addressing is in hexadecimal. What is true RMS? RMS stands for "Root-Mean-Square." True RMS is the power from AC voltage/current that will produce the equivalent amount of heat in a resistor as a DC voltage/current, whether sinusoidal or not. For example, if a resistive heating element is rated at 15 kW of heat at 240 Vac RMS, then the heat would be the same if we applied 240V of DC instead of AC. A meter without true RMS will incorrectly read distorted waveforms. How accurate are the MD-P1 and MD-P1D Power Meters? The MD-P1 or MD-P1D Power Meter’s accuracy is better than 1%. What is the lead length for Rogowski Coil CTs? The maximum lead length for the Rogowski Coils is 100 feet (30 meters). How do I update the firmware? Currently, the MD-P1 and MD-P1D Power Meters must be in USB mode to use ViewPoint to update the firmware (either through the software switch or the rotary switches). See Appendix E. Glossary Word Description Amp Multiplier A multiplier that changes amperage so that a meter can read higher measurements. Analog Value A type of BACnet object that is a floating point number. On the MD-P1 and MD-P1D Model Power Meters, Analog Value objects are used to represent the electrical measurements. BACnet Building Automation Control networks. A communications protocol that allows building automation and control devices and their association properties (objects) to be automatically discovered. 63 Siemens Industry, Inc. 125-201 2014-09-19 Frequently Asked Questions - FAQs Glossary Word Description CAM Clear All Measurements Data Scalar A scalar is used to multiply the raw data value to convert information read from the registers Demand Window The Demand Window is how long the meter calculates your demand for recording a value. For example if your Demand Window is set to 15 minutes, the meter will calculate your total demand every minute for 15 minutes. At the end of the 15 minutes it will sum all 15 values, and then record that value as the demand. Digital Output The MD-P1 and MD-P1D Power Meters have an output port. The port can be used to output kWh, kVARh,or kVAh pulses to external devices, or to toggle on and off to control a remote device or relay. Discovery In BACnet, devices and the objects they expose can be found through a discovery process. This means that devices and objects do not need to be manually added if a BACnet client supports discovery. Falling edge Transition of the input signal from high to low. Hexadecimal In mathematics and computer science, hexadecimal (or hex) is a numeral system with a radix, or base, of 16. It uses sixteen distinct symbols, most often the symbols 0 to 9 to represent values zero to nine, and A, B, C, D, E, F (or a through f) to represent values ten to fifteen. kVAh Kilovolt-Ampere Hour kVARh Kilovolt Ampere Reactive Hours kWh Kilowatt Hour LSW (Modbus mode only) Least Significant Word. Unit of data with the loworder bytes at the right. MS/TP Master-Slave/Token Passing is a model of communication used by BACnet where one device (the master node) has unidirectional control of the RS-485 serial bus. The token is passed from master node to master node to allow a master node to send frames over the bus. MSW (Modbus mode only) Most Significant Word. Unit of data with the highorder bytes at the left. Net When a register/object has the word “net” in its description, the net equals the sum of all individual signed measurements. Object A BACnet object is a standard data structure that on the MD Model Power Meter represents electrical measurements. Power Factor The power factor of the AC electric power system is defined as the ratio of the real power flowing to the load to the apparent power, and is a number between 0 and 1 (frequently expressed as a percentage, for example, 0.5 pf = 50% pf). Real power is the capacity of the circuit for performing work in a particular time. Apparent power is the product of the root mean squared current and root mean squared voltage of the circuit. Due to energy stored in the load and returned to the source, or due to a non-linear load that distorts the wave shape of the current 64 Siemens Industry, Inc. 125-201 2014-09-19 Frequently Asked Questions - FAQs Glossary Word Description drawn from the source, the apparent power can be greater than the real power. Pulse Input Used for counting, accumulating, and scaling pulses received from non-DENT external pulse initiating meters such as gas, water, or other electrical meters. Pulse Output Pulse output is used to generate pulses for external devices such as data loggers that can accept pulses. The MD-P1 and MD-P1D Power Meters can generate pulses based on accumulated value(s) such as system kWh, system kVARh, and system kVAh. Rising edge Transition of the input signal from low to high. RMS Root-Mean-Square. True RMS is the AC voltage/current that produces the equivalent amount of heat in a resistor as a DC voltage/current, whether sinusoidal or not. The MD Model Power Meter measures true RMS. RS-485 EIA-485 is used as the physical layer underlying many standard and proprietary automation protocols used to implement Industrial Control Systems, including BACnet/Modbus/P1. RTU A Remote Terminal Unit (RTU) is a microprocessor controlled electronic device which interfaces objects in the physical world to a distributed control system, or a SCADA system by transmitting telemetry data to the system and/or altering the state of connected objects based on control messages received from the system. SCADA Supervisory Control And Data Acquisition. It generally refers to an industrial control system: a computer system monitoring and controlling a process. Service A BACnet service is a message that the MD-P1 and MD-P1D Power Meters must respond to. In BACnet these include WhoIs, I-Am, and ReadProperty. Volts Multiplier A multiplier that changes voltage so that a meter can read measurements higher than 600V. 65 Siemens Industry, Inc. 125-201 2014-09-19 Issued by Siemens Industry, Inc.
