Standard-compliant energy management optimizes energy utilization, while continuously enhancing energy efficiency. As a second step, basic energy consumption and cost data, as well as information on in-house energy production, must be collected and documented clearly and verifiably. This requires the development of a reliable and precise system for the capture and analysis of consumption data. The objective is to recognize sustainable savings potential, to derive appropriate measures for that potential, and to implement these measures systematically. Defining energy policy objectives A central management task is the formulation of an in-house energy policy. It defines relevant strategic and operational objectives. Ongoing planning will include the identification of additional optimization potential for the business areas under scrutiny, and the development of relevant improvement measures. Introducing process optimization Periodic controlling Periodic checks will ensure that your energy management system functions correctly, and that objectives are reached. Corrective and preventative measures can then be implemented as needed. As a first step, an energy manager must be identified and nominated. He will then evaluate captured data, and derive and implement appropriate optimization measures. He will report the achieved results to corporate management. Energy policy objectives Process optimization Strategic Operational Introduction Implementation Continuous improvement due to energy management acc. to ISO 50001 Corrective measures Preventative measures Periodic controlling Monitoring Measuring Analysis Consumption data capture/analysis Introduction of a corporate energy management system in accordance with ISO 50001 for continuous improvement of energy efficiency by reducing energy consumption and costs. 2 Siemens * 10/2015 (c) Siemens AG 2016 Measuring Devices and Power Monitoring Power Monitoring Energy management in accordance with ISO 50001 Providing the basis with power monitoring The power monitoring system from the SENTRON portfolio is suitable for infrastructure, industrial applications, and buildings.

Mounting of the 7KM PAC3100, 7KM PAC3200 and 7KM PAC4200 To mount the devices they are inserted from the front through the square cutout in the control cabinet door and secured with the supplied combination latching holders. From the front, i.e. in the installed state, the device thus complies with safety class II with degree of protection IP65. The header bar shows in plain text which measurement values are presented in the current display. For easier navigation, the menu number of the display is shown on the far right. The measured values with phase identifer and unit of measurement are shown in the middle of the display. The scrollbar and the menu number in the display header together indicate in which display or parameter menu you are, thus enabling fast and selective navigation. As the result of the easy-to-use combination latching holders and the small mounting depth it is easy to mount several devices side by side. The following illustration of the rear view of the 7KM PAC3200 and top view of the expansion module (in this case: 7KM PROFIBUS DP) shows by way of example how the 7KM PAC3200 and the expansion module are joined together. An expansion module is mounted on a 7KM PAC4200 in similar manner. Four function buttons with context-sensitive descriptions for operating the device. NSE_01947 The pair of combination latching holders performs two functions: * Thanks to the latching mechanism the fitter can fasten the device in the control panel quickly and without the use of any tools. * If greater protection is required, the four latching holder screws can be used to increase contact pressure evenly on all sides so that the control panel cutout is completely sealed by the integrally molded gasket, which is a standard feature. It is no longer necessary to insert an accessory gasket in addition. Device front of the 7KM PAC 3100, 7KM PAC3200 and 7KM PAC4200 measuring devices (here for example the 7KM PAC3200) The devices are operated using 4 function keys, which correspond to the 4 text fields situated above them. The key are each assigned with several functions; their function at any time depends on the menu then displayed. Which function a key has in the respective menu is indicated by the text in the related display. 16 Siemens * 10/2015 (c) Siemens AG 2016 Measuring Devices and Power Monitoring 7KM PAC Measuring Devices Technical specifications and project planning aids Function Precise measurement of variables 7KM PAC3100 measuring device The 7KM PAC3100 measuring device provides Class 1 measuring accuracy for voltages, currents, active power, apparent power, and active energy (in accordance with IEC 61557-12). 7KM PAC3200 measuring device With its high accuracy, the 7KM PAC3200 meets the increasing demand for precise power measurement. It satisfies the accuracy requirements of Class 0.5S according to IEC 62053-22 for electronic active consumption meters. 7KM PAC4200 measuring device The 7KM PAC4200 measuring device supplies measurement data of far greater accuracy for determining and processing power data and for assessing the quality of the network: * For voltage, current, active power and active energy the device achieves for example Class 0.2 according to IEC 61557-12. * For active energy this corresponds to Class 0.2S according to the international meter standard IEC 62053-22. The 7KM PAC4200 thus meets the accuracy requirements of the high-precision meters used by the power supply companies, which are normally reserved for exacting industrial applications. Transparency in power matters Altogether 10 power meters for active, reactive and apparent energy monitor the power import and power feedback continuously and separately according to high tariff and low tariff. In addition to the continuous counters for apparent, active and reactive energy, the 7KM PAC4200 saves the power consumption levels per day for a period of 365 days. A cut-off date assessment accurate to the day is possible by entering the required calculation period. The power consumption for a preselected period can be called up either directly on the device or by using the communication interface. Load profile recording with the 7KM PAC4200 As soon as the power draw conditions per demand period or also reactive energy components affect the power costs it is important to obtain an exact picture of your own plant's load profile. With its generously sized memory, the 7KM PAC4200 is ideal for this purpose. With a set demand period of 15 minutes it records the load profile for apparent, active and reactive power with minimum and maximum values for import and feedback over a period of 40 days. The recording duration can be increased or decreased depending on the demand period selected. The demand period can be synchronized to the period of the power supply company so that the measured data can be compared with the power supply company's records. This can be done using either one of the digital inputs or a synchronization command via the communication interface. If no synchronization option is available, the device synchronizes itself with its internal clock. For load profile recording the 7KM PAC4200 supports the fixed block method (only one demand period) or the rolling block method (division of the demand period into several sub-periods). In addition it is possible to choose between arithmetic or cumulated power demand calculation. Load profile recording can be individually adapted with the powerconfig configuration software. Powerful communication 7KM PAC3100 measuring device The 7KM PAC3100 measuring device has an integrated RS 485 port and can be operated with the Modbus RTU protocol. Ethernet interface (7KM PAC3200/4200 measuring devices) The 7KM PAC3200/4200 measuring devices have an Ethernet interface as a standard feature which can be used not only for configuration purposes using powerconfig but also for system communication in a higher-level power management system. This makes additional hardware superfluous. The 10 Mbit/s Ethernet interface of the 7KM PAC3200 permits one communication connection while the 10/100 Mbit/s Ethernet interface of the 7KM PAC4200 permits three such connections simultaneously. Both devices support the Modbus TCP protocol. The Ethernet interface of the 7KM PAC4200 offers not only a higher data transmission rate but also additional functions: * Auto MDI(X) (auto crossover) and auto negotiation * Serial gateway for connecting devices with an RS 485 interface to an Ethernet network Daily counter indicator of the 7KM PAC4200 The 7KM PAC3200 and 7KM PAC4200 measuring devices supply the required power demands for active and reactive power for load profile recording and serve as reliable suppliers of data for a higher-level power management system. PROFIBUS DP interface (7KM PAC3200/4200 measuring devices) Use of the power monitoring devices in PROFIBUS DP is made possible by the optionally available 7KM PAC PROFIBUS DP expansion module. Integration in PROFIBUS DP takes place using a standardized text file, the device master data file (GSD). This GSD file is read into the master with the help of the PROFIBUS configuration tool. The master thus receives the slave-specific communication framework of the PAC3200 or PAC4200 and can start cyclic operation immediately. With DP V1 the PAC PROFIBUS DP expansion module also supports acyclic data traffic. Modbus RTU interface Use of the power monitoring devices in Modbus RTU fieldbuses is made possible by the optionally available PAC RS 485 expansion module. Integration in Modbus RTU systems takes place through parameterization of the device address and baud rate using the device keyboard or via powerconfig. Siemens * 10/2015 17 (c) Siemens AG 2016 Measuring Devices and Power Monitoring 7KM PAC Measuring Devices Technical specifications and project planning aids The 7KM PAC4200 provides comprehensive information about events Voltage failures, limit value violations, switching operations, device configuration changes, counter resets or deleting of the memory are just some of the possible events which the 7KM PAC4200 records and saves to the events list. The integrated memory has space for more than 4000 operation, control and system-related events, which the user can organize according to his requirements. For example, in addition to the three selectable alert levels for information, warning or alarm it is possible to choose the priority of each event independently of each other. And it is also possible of course to choose whether an event is to be recorded at all and in which order the events are to be shown on the display. Multifunctional digital inputs and outputs The 7KM PAC3200 measuring device is equipped with one digital input and output each, and the 7KM PAC3100 and 7KM PAC4200 measuring devices with two multifunctional digital inputs and outputs, to each of which various functions can be assigned. Functions of the digital inputs: : 3200 4200 Number of integrated digital inputs 2 7KM PAC measuring device 3100 1 2 Count input for energy pulses (kWh, kvarh) from third-party devices -- Status monitoring of a switching device Tariff switching between high tariff and low tariff -- Signal input for synchronization of the demand period -- Time synchronization of the internal -clock to a master clock -- + any energy form Functions of the digital outputs: 7KM PAC measuring device 3100 Three-level event displays on the 7KM PAC4200 Events are displayed in three levels: * Popup window for signaling important events, e.g. in the case of alarm messages. Mandatory acknowledgment is selectable for particularly important events * Events list for clear representation of the individual events with symbols indicating the alert level * Detail window with particulars of the event, e.g. event class, date and time of occurrence, reason for triggering the event and, where applicable, the measurement variable in question with its measured value and limit value Event recording can be configured with the powerconfig configuration software. Plain-text displays A large, fully graphic LCD display enables easy reading even from great distances. To make sure that this is also the case in poor light conditions, the backlighting can be individually adapted to the actual requirements. In addition to the standard displays of the 7KM PAC3100/3200, the 7KM PAC4200 measuring device offers up to four userdefinable displays. These displays can be used for individual arrangement of the desired measured variables and for their representation as bar or digital displays. Operation, also multilingual Operation is quick to learn thanks to the intuitive user guidance using the four function keys in conjunction with multilingual plain text displays. The experienced operator can also use direct navigation for quicker selection of the desired display menu. Following languages can be selected: English, Chinese, French, German, Italian, Portuguese, Russian, Spanish and Turkish. The product documentation is also available in 9 languages. 3200 4200 Number of integrated digital outputs 2 1 2 Pulse output for sending energy pulses (kWh, kvarh) Alarm output for signaling limit value violations -- Operating status display -- Direction of rotation indicator -- Switching output for remote control via system software Synchronization of third-party devices to own demand period -- -- Available -- Not available Monitoring of measured variables for limit value violation (7KM PAC3200 and 7KM PAC4200 only) The 7KM PAC3200 has a function for monitoring up to 6 measured variables, and the 7KM PAC4200 up to 12 measured variables, for violation of an adjustable upper or lower limit value. The following variables can be monitored: Voltage, current, power, power factors, THD for voltage and current, frequency, unbalance of voltage and current. In addition it is possible with the 7KM PAC4200 to monitor the phase angle, distortion current strength, individual line harmonics from the 3rd to the 31st harmonic, and sliding window demand values. The following can be assigned to each limit value: * A measured variable * The monitoring mode (overshooting or undershooting) * A limit value * A delay time and * A hysteresis It is possible to select the action to be triggered by violation of a limit value. For example, a signal can be sent through the digital output or the communication interface. The integrated universal counter can be used to total the number of limit value violations. Whether a limit value has been violated is indicated on the device. 18 Siemens * 10/2015 (c) Siemens AG 2016 Measuring Devices and Power Monitoring 7KM PAC Measuring Devices Technical specifications and project planning aids Interconnected with logic operations ... Universal in use The 7KM PAC3200 and 7KM PAC4200 measuring devices have a function for interconnecting limit values using logic operations as follows: * 7KM PAC3200: AND/OR * 7KM PAC4200: AND/OR/NAND/NOR/XOR/XNOR The 7KM PAC3100, 7KM PAC3200 and 7KM PAC4200 can all be used for measuring in two, three and four-wire networks. Singlephase, two-phase and three-phase measurements are possible. Like the individual limit values, the result of the logic operation can also trigger selective actions, which were previously described in the section "Monitoring of measured variables for limit value violations". ... and conveniently programmed with the 7KM PAC4200 In addition to the interconnection of limit values it is also possible with the 7KM PAC4200 to include the digital inputs in the logic operation. On the 7KM PAC4200 the logic operations are configured in user-friendly manner using a graphic programming interface. To each of the 5 logic gates it is possible to assign 4 random inputs (limit value or digital input) and one logic function (AND, OR, NAND, ...). From the small black bar at the inputs of the gates the user can see the state of the input at a glance. Thanks to their large measured voltage range, the devices can be directly connected in every low-voltage system up to a rated line voltage of 690 V (UL-L)1) . Higher voltages can be measured using voltage transformers. For measuring currents it is possible to use both x/1A and x/5A current transformers (for 7KM PAC3100 only x/5A x/5A current transformers). Transformer ratios and current direction can be programmed on the device for adaptation to local conditions. Protection against unauthorized access The 7KM PAC3100, 7KM PAC3200 and 7KM PAC4200 come with integrated password protection so that the energy and parameter data are safe from unauthorized access. Changes to the parameterization can be traced using a configuration counter which can be read out through the communication interface. 1) Max. 500 V (UL-L) for version with DC power supply unit with extra-low voltage (7KM2111-1BA00-3AA0) Logic operations with limit value events on the 7KM PAC4200 measuring device Monitoring of voltage and current for unbalance (7KM PAC4200 only) The 7KM PAC4200 measuring device measures, among other things, the unbalance of voltage and current in the line. Now that a limit value can also be assigned to these two parameters, problems due to unsymmetrical loads in the installation can be detected early on and avoided. Operating hours counter (7KM PAC3200 and PAC4200 measuring devices) An important service function is performed by the integrated operating hours counter, which can be used to monitor e.g. pumps, motors or machines. The counter measures the runtime of a connected load, helping to ensure that important maintenance intervals are observed. The count can be read out and evaluated by a PC. A higher-level power management system is thus able to generate relevant maintenance information.

It provides the following features: * Standardized PROFIenergy interface to the measured quantities * The measured quantities can be individually selected using a GSDML file. This permits use of cost-effective S7 CPUs * Easy parameter assignment using the device display and STEP 7 * Integrated Ethernet switching allows networking with short cables without additional switches * Direct integration in production machine networks using IRT (IRT = Isochronous-Real-Time) * Full support of PROFINET IO (DHC, DNS, SNMP, SNTP) * Device replacement without PG in the PROFINET assembly using LLDP * Deterministic reversing time through ring redundancy (MRP) * Modbus TCP communication * Communication with powermanager or powerconfig * 2 x Ethernet (RJ45) sockets * Transmission rates 10 and 100 Mbit/s * Protocols PROFINET IO, PROFIenergy and Modbus TCP * No external auxiliary power necessary * Status display via the device display and via LEDs on the module All measured variables from 7KM PAC3200 and 7KM PAC4200 can be individually selected and cyclically transmitted by means of the GSDML file. This enables optimum use of the process image of the PROFINET controller, e.g. CPU 315-2 PN/DP of SIMATIC S7. The measured variables can be read out in acyclic mode using PROFIenergy, a PNO protocol profile. Thanks to PROFIenergy, it is possible to assemble a power monitoring system with devices from various manufacturers using PROFINET. 32 Siemens * 10/2015 (c) Siemens AG 2016 Measuring Devices and Power Monitoring 7KM PAC Measuring Devices 7KM PAC expansion modules Version Use in PAC3200 PAC4200 PAC5100 PAC5200 COM800/ COM100 7KM PAC PROFIBUS DP expansion module 3VA PAC3100 7KM PAC -- -- -- -- -- -- -- -- -- -- -- -- The 7KM PAC PROFIBUS DP expansion module is a plug-in communication module for 7KM PAC3200 and 7KM PAC4200 measuring devices and 3VA molded case circuit breakers.

These multimeters allow users to define their own standard for measured variables per display field, so that they can be implemented far more universally and flexibly. A special feature is the analysis of the different loads on the phases. Phase displacement and unsymmetrical or unbalanced loads can cause partial overloads. These multimeters offer a range of different options for combining and assessing measured values. The display fields are selected using rotary pushbuttons and the desired indications confirmed with OK. By making the horizontal selection e.g. W, V, A or p.f., and the vertical selection, e.g. L1, L1-L2 or L, users can then define the desired measured variables for this display field. The vertical data on the display can be assigned to any measured value in the horizontal data. The letters M(ega) and k(ilo) are automatically assigned according to measuring range, i.e. measured value, e.g. kW or MW. Capacitive loads are automatically indicated by a capacitor, inductive loads by a coil.

Once terminal 3 is supplied with voltage (for DC "+"), the counting procedure starts. If terminal 4 is supplied short-time with voltage (for DC "+"), the counter is reset. In the case of electronic counters, the counting result is saved indefinitely in the event of a power failure (EEPROM). On recovery of the power, the counting is continued from the saved value. As well as a modern design, the electronic counter has a 7-digit LCD, which can be reset electrically or manually. 7KT582. 7KT5833 Circuit diagrams Connections 2(L) 2(+) 2(+) 2(L) M M 3(N) 3(-) 7KT5801 7KT5802 7KT5803 7KT5804 7KT5806 7KT5807 Count Reset K1 K1 K2 3 4 7KT5821 54 1 2 3 4 I201_11288b Count I201_11616b 2 3(N) 7KT5812 7KT5814 +/~ -/~ L1(+) N(-) +/~ -/~ L1(+) N(-) 1 3(-) 7KT5811 7KT5822, 7KT5823, 7KT5833 Siemens * 10/2015 (c) Siemens AG 2016 Measuring Devices and Power Monitoring Other Measuring Devices Time counters for front-panel mounting Overview Time and pulse counters for control cabinets, control systems and mechanical engineering are used, e.g. in boilers, machine tools or compressors.

Pin-wound transformers: An economical solution especially for small primary currents of 5 ... 75 A are window-type current transformers when the conductor to be measured is pin-wound several times. Current transformers can be continuously loaded with 1.3 times the primary rated current (Ipn). Particularly suitable for longer measuring leads. Cable losses of only 4 % in contrast to 5 A current transformers. 5 A current transformers generate 25 times the power losses on measuring leads as compared with 1 A current transformers. These stray losses result in higher power in the case of long cables. Only recommended for use with short measuring leads. Operation measurement, internal metering Current error 1 % at 1 x Ipn and 1.2 x Ipn Class 3 Coarse measurement Current error 3 % at 0.5 x Ipn and 1.2 x Ipn Rated power Pn The rated power of transformers is specified in VA. The actual load rating should be similar to the rated power; a lower actual load rating (underburden) increases the overcurrent factor and measuring devices are not sufficiently protected in case of a short-circuit, a higher actual load rating (overburden) has a negative effect on the accuracy. With a frequency of 60 Hz the rated power increases to 1.2 times. With 162/3 Hz the output power decreases to 1/ of the rated power. 3 This is the rms value of the maximum voltage between the conductors of a system. For this voltage the insulation must be rated at normal operating conditions. 4NC5 current transformers are suitable for 720 V. The overcurrent limiting factor is expressed using the characters FS and a factor, e.g. FS5 or FS10. When a short-circuit current flows through the primary winding of a current transformer, the stress on the measuring devices connected to the current transformer is the lower the smaller the overcurrent limiting factor is. The thermal rated short-time current Ith is the rms value of the primary current with a duration of one second, whose heat effect the current transformer can resist without being damaged in the event of a short-circuited secondary winding. The rated impulse current Idyn is the highest instantaneous value of the current after a short-circuit whose force the current transformer can resist without being damaged. The rated impulse current is specified as peak value.
