4 Power Monitoring and Control Systems Introduction Profitability with power monitoring If you knew where and how to cut peak demand power usage, you could lower your electric bills and your company s cost of product. But how can you, when you have no idea how your demand patterns relate to production? Perhaps you would like to stretch this year s budget by deferring the purchase of a new substation, but you are not sure you have enough capacity to accommodate the vital new process equipment you need to install. Take a chance and the whole line could go down at who knows what cost in downtime. If you only knew where and how much excess capacity you have. Electric utility deregulation is changing the way you buy electricity. But do you know all you need to know about your electrical needs, including the quality of power needed, in addition to knowing when and how much power is needed? Electricity once considered an uncontrollable cost of doing business is brought under control through power monitoring and control systems. With The POWERLOGIC system provides the information you need to control utility costs and, perhaps more important, downtime costs. a power monitoring and control system, a facility engineer has the ability to locate trouble spots and prevent outages or downtime, as well as determine energy use by department or product line. The POWERLOGIC Power Monitoring and Control System from Square D is an innovative total system solution to managing electricity and improving the reliability of power distribution equipment. The POWERLOGIC system combines microprocessor-based instrumentation and control to provide advanced features for industrial, commercial and utility electrical systems. The POWERLOGIC system s exceptionally accurate instruments, highspeed communications network, and fully integrated power monitoring application software make these benefits possible. Controlling costs to maximize profits One of the keys to maximizing profit is by controlling costs. A power monitoring system helps you do that in two ways. It allows you to better know the impact electrical costs have on your operating costs, and gives you the information you need to purchase electricity more cost effectively. From the personal computer on your desk, you can run the world s most powerful monitoring and control system: the POWERLOGIC system. Reduction of downtime Minimizing downtime is critical to the profitability every operation. Unexpected power outages and having key pieces of equipment shut down suddenly is expensive due to the time required to find the source of the problem, correct it, and get production started again. The loss of product adds additional expense. The key is to identify potential problems and correct them proactively. For example, the current on a critical motor may have become higher than normal. A bearing may be failing. The power monitoring system s overload alarm alerts the operator of the situation so the problem can be identified and corrected with a minimum of downtime. 4

5 Improve power quality Power quality concerns include making sure the power delivered to critical machines and processes is both clean and dependable. Computers and microprocessor-based control systems are very sensitive to the quality of power they use. The first step to solving power quality problems is to determine the magnitude of the problem. This is one of the functions of the power monitoring system. Lower energy costs The power monitoring system can help lower energy costs in several ways. First, demand charges can often be reduced through the analysis of maximum and minimum readings and reviewing time and trend plots of data logs. Alarms can be triggered to warn when the system is in danger of creating new peaks. Second, power factor penalties can be reduced by using power factor correction capacitors (PFCs). But to use PFCs correctly, you need to know what your power factor is and the harmonic content of the circuit. The power monitoring system can be used to determine when and where capacitors should be used. Finally, the POWERLOGIC system provides you with the information about your power requirements so you can take full advantage of the electrical utitlity deregulation opportunities. Allocate energy costs More and more companies want to know not only how much energy they are using, but where they are using it. Competitive pressures necessitate knowing all the costs associated with a product, including the cost of power to produce it. In addition, efforts to closely manage energy costs are easier to evaluate when the costs are broken down by area. The POWERLOGIC system can create the trend plots and reports allocating the energy costs the way you need them. Better utilization of power distribution equipment A common question asked is Does the existing distribution equipment have enough capacity? A power monitoring system with the POWERLOGIC software displays the data logs in the form of time trend plots. Peak information from date and time stamps of maximum readings is also useful. This shows which distribution equipment is under utilized, or near overload. All this information can be used to obtain the maximum use of existing equipment, and to more accurately design future distribution equipment. POWER MONITORING & CONTROL SYSTEMS Power Monitoring and Control Systems Introduction Special monitoring and control systems Power monitoring is often just part of the solution. Monitoring other utilities such as gas, water, and steam may be needed. Sequence of events monitoring can be critical. Monitoring and control of generators and transfer switches may be required. Automatic control systems for Typical POWERLOGIC power monitoring and control system. 5

6 Power Monitoring and Control Systems Introduction shedding and restoring loads may be key to minimizing energy costs or maintaining critical circuits. There are POWERLOGIC solutions for all these systems. How do power monitoring and control systems work? Power monitoring systems monitor the flow of electrical power in circuits throughout the plant. In the POWERLOGIC system, highly accurate circuit monitors and power meters are dedicated to power monitoring, while other compatible devices collect additional equipment information from protective relays, circuit breakers, transformer temperature controllers, and panelboards. Electrical data such as current, power, energy, waveforms, and equipment status is passed over a data network to one or more personal computers. The personal computers run power monitoring application software that retrieves, stores, organizes, and displays real-time circuit information in simple, usable formats. The information collected and stored in a power monitoring system helps operate a facility more efficiently. Of course, the quality of the data depends on the accuracy of the instrumentation and the usability of the display formats. A POWERLOGIC system provides this accuracy in a format that is easy to use and understand. Accurate monitoring devices Each POWERLOGIC monitoring device is a multi-function, digital instrumentation, data acquisition device capable of replacing a variety of meters, relays, transducers, and other components. POWERLOGIC system devices can be integrated with Square D s electrical power distribution products or retrofit into existing equipment. The result is a distributed network of intelligent, accurate monitoring devices reporting to one or more centralized locations. Flexible connectivity and network topologies All POWERLOGIC-compatible devices are equipped with an RS-485 network communication port for integration into a POWERLOGIC power monitoring and control system. Up to 32 devices can be daisy-chained and directly connected to a personal computer, system display, Ethernet gateway (TCP/IP and OSI), or POWERLOGIC network interface module (PNIM). Square D can provide industrially hardened local area networks, or connect to existing networks, either local or wide area. Other communication options such as fiber optics and modems, including telephone and radio, are also available. The POWERLOGIC system makes it easy to allow localized, distributed, remote, and any mixed network combination. 6 No other monitor gives you more standard communications capabilities than the POWERLOGIC circuit monitor. And once the data gets to your computer, there s no better way to make sure of all the information than System Manager 3000 software. Powerful software solutions The POWERLOGIC application software series offers a variety of power monitoring solutions, allowing you to monitor, display, and store vast amounts of information from all of the POWERLOGIC compatible devices. Organized and usable information The POWERLOGIC application software series automatically integrates real-time circuit information into organized and usable formats. Without any custom

7 Power Monitoring and Control Systems Introduction programming and very minimal setup, the user can readily access real-time and historical data, time trend plots, alarms, waveform plots, power quality information, data logging, output control, and more. Evaluation, engineering, and support Square D s Power Management Organization is more than power monitoring devices and software. It includes highly trained and capable engineers evaluating and providing solutions to power quality issues. To ensure smooth installation and system commissioning, our application engineering services are available to oversee the project from design to completion. The POWERLOGIC University provides users with the training needed to get the most out of their system. And finally, the Technical Support Group provides the answers to the questions to ensure smooth operation of your power monitoring system. Information is power If you can t measure it, you can t control it. And controlling costs is critical. POWERLOGIC power monitoring systems provide you with the information you need to make the sound business decisions needed in today s marketplace. See all those meters? A single POWERLOGIC power meter or circuit monitor can do their work and that of many others. Yet it costs less than what you d pay for just a few of them. 7

8 Power Meters Features The POWERLOGIC Power Meter is capable of replacing a full complement of basic analog meters. This cost effective, high performance meter can operate as a stand-alone device or as part of a POWERLOGIC Power Monitoring System to help reduce energy and maintenance costs by providing Economical Metering Solution A single, economical device that replaces a full complement of analog meters Accurate true RMS metering of distorted currents and voltages up to the 31st harmonic THD readings for each metered phase of current and voltage to assist in measurement of power quality data Neutral current monitoring to detect overload neutrals Individual machine load monitoring Available feeder capacity monitoring (peak demand current) Load monitoring for predictive maintenance/troubleshooting Remote meter reading and data logging from a personal computer using POWERLOGIC System Manager software and RS-485 communications Ease of Installation Display mounts in panel cutout of standard 1% analog meters Separate meter and display modules allows flexible mounting options Easy retrofit into existing power equipment Direct Connect Up to 600 V No PTs required up to 600 V No separate control power required on up to 600 V circuits Communications Options POWERLOGIC communications for integration with a POWERLOGIC power monitoring system Modbus RTU communication for integration with other systems KYZ pulse initiator for communication to energy management systems 2-Line LCD Display Mounts back-to-back or up to 50 feet from power meter module Use as a portable power meter programmer Provides setup and display of metering information Provides optical isolation from 600 V metering connection Designed for Reliability Tested for compliance with UL and CSA requirements FCC compliant (Class A) CE marking Vibration and temperature tested valuable power information. 8

9 Power Meters Basic Metering Solution and More The POWERLOGIC Power Meter is designed for use in basic power metering applications. It can replace conventional metering devices such as ammeters, voltmeters, and watt-hour meters while providing powerful capabilities not offered by analog metering. The power meter s true rms readings (31st harmonic response) accurately reflect non-linear circuit loading more than conventional analog metering devices. The power meter calculates the neutral current, which can assist in identifying overloaded neutrals due to either unbalanced single phase loads or triplen harmonics. Circuits can be closely monitored for available capacity by keeping track of the peak average demand current. Accurate circuit loading information is essential to get the most out of existing power equipment while maintaining power system reliability. The power meter provides a full complement of accurate true rms metering values through the optional display, or via the standard RS-485 communication port to a POWERLOGIC Power Monitoring and Control System. A model PM-600 power meter module replaces a full complement of basic analog meters including a watt-hour meter. The model PM-620 power meter module extends the metering capabilities to report power and current readings including the date and time of occurrence. The model PM-620 also provides neutral current and per phase THD for each metered current and voltage. Refer to the tables for information about the metering values reported by each model. A KYZ output is included to communicate energy and demand information to third party energy management systems. Meter Feature Values Model Model PM-600 PM-620 Current, per phase A, B, C Current, neutral N Volts, L-L A-B, C-B, C-A Volts, L-N A-N, B-N, C-N Real power (kw) A, B, C, total Reactive power (kvar) A, B, C, total Apparent power (kva) A, B, C, total Power factor (true) A, B, C, total Frequency Current demand A, B, C, N, present & peak Real power demand (kwd) 3 phase total, present & peak Reactive power demand (kvard) 3 phase total, present & peak Apparent power demand (kvad) 3 phase total, present & peak Real energy (kwh) 3 phase total Reactive energy (kvarh) 3 phase total Apparent energy (kvah) 3 phase total Energy accumulation modes Signed, absolute, energy in, energy out KYZ output RS-485 POWERLOGIC and Modbus RTU communications Date/time stamping Peak demands, power up/restart, resets THD, voltage & current A, B, C POWERLOGIC Power Meter Feature Comparison Mounting Flexibility The power meter s small size and variety of mounting configurations allow it to be readily installed in new equipment or retrofit into existing equipment. The power meter module can be mounted onto a 35mm DIN rail, or it can be mounted on any flat surface using its four mounting feet. For added simplicity in retrofit installations, the panel mounting hole patterns for both the power meter module and the optional power meter display match the conventional 4-inch ammeter/voltmeter spacing so the meter and the display can be mounted back-to-back on opposite sides of a panel surface. In metering installations of 600 V and below, the power meter provides additional savings in both cost and mounting space by eliminating the need for PTs and control power transformers. Versatile Display The optional power meter display mounts in the same space as a conventional 4-inch ammeter and is connected to the power meter module with a communication cable. With the 2-line by 16-character LCD display, the user can view metering data, and access the password protected meter setup and resets menus. Since the power meter display can be mounted up to 50 feet Power Meter Display Power Meter Module away from the power meter module, power metering can now be installed in tight equipment spaces without sacrificing convenient and affordable local display. The communications port on the power meter display is optically isolated from the 600 V metering connections. 9

10 Power Meters Power Meter Display (PMD-32) 4 Power Meter Module (PM-600 or PM-620) Power Meter Module and Display Features 2-line x 16 character LCD display Tactile function keys Multi-conductor communication cable (up to 50 feet) Control power, metering KYZ and communications connections Panel or DIN rail mounting Removable terminal shield Powerful Functionality The power meter accepts inputs from standard 5 A CTs and has full scale input of 10 A. The voltage inputs can be directly connected to 3 phase circuits of 600 V and below without the need for PTs or CTs. For higher voltage circuits, the power meter accepts a full range of PT primary values with control power derived from the PTs or from a separate source of ac or dc control power. Setup and resets are password protected and are easily done through the power meter display or via the network using System Manager software, releases SMS-3000, SMS-1500, and PMX From the optional display, POWERLOGIC or Modbus RTU protocols can be selected. No DIP switches or other hardware adjustments are required for setup. All readings are scaled to their actual values without the need for a multipler. POWERLOGIC System Compatibility The power meter supports standard POWERLOGIC RS-485 communications up to 19,200 Baud with communications links up to 10,000 feet. A meter can quickly be installed into any existing POWERLOGIC system. The power meter has been fully integrated into the latest POWERLOGIC application software, System Manager software, releases SMS-3000, SMS-1500, and PMX This software enables users to manage their electrical distribution systems by providing tabular and graphical data displays, alarms, real time and historical time trend tables and graphs, and reports. Power meter setup and reset operations and wiring diagnostics can also be performed from a remote personal computer using the software. POWERLOGIC power monitoring devices and systems assist in equipment monitoring for cost allocation, troubleshooting, predictive maintenance, planning, and more. The lower installed cost of the power meter makes it possible for facilities to monitor many smaller, less critical feeder circuits enabling whole facility power monitoring. 10

13 Circuit Monitors Comprehensive Metering The POWERLOGIC Circuit Monitor installs on a 3-phase circuit like a conventional watthour meter, but it delivers far more information. In fact, the circuit monitor can replace more than 100 conventional indicating meters. All circuit monitors perform highly accurate, true rms metering. The CM-2050 offers comprehensive metering with 1% accuracy on current and voltage. Models CM-2150 and higher provide 0.2% accuracy on current and voltage, and 0.4% accuracy on power and energy. Protective Functions A circuit monitor equipped with an I/O module can perform certain motor protective functions. These include phase loss, phase reversal, under voltage, and more. Once the circuit monitor detects the abnormal condition, the output relay switches within 1 3 seconds. Each protective function can operate one or more form-c, 10 ampere relays. Each relay can be activated by multiple protective functions. These functions are password protected. Power Quality Readings Total Harmonic Distortion (THD) for current, voltage, and k-factor readings indicate potential power quality problems which, unchecked, could disrupt critical processes or damage equipment. Programming Capabilities The CM-2450 Circuit Monitor is programmed using simple math functions, timers, and compare statements to customize data logging, control functions, and more. For example, you could write a program that logs data by exception rather than at regular intervals, thus maximizing the circuit monitor s memory. Meter values can be analyzed in the circuit monitor and summarized in daily, weekly, and monthly reports. Easy Setup Basic circuit monitor setup can be performed from either the front of the circuit monitor, or a personal computer running POWERLOGIC application software. The PC connects to the circuit monitor using either the system network or an optical communications interface. No thumbwheel or DIP switches are involved; therefore, after installation, setup parameters such as the unit address, CT ratio, PT ratio, and baud rate can be configured without exposing personnel to live conductors. For security, all setup information is password protected.

Flexible Communications Optically isolated RS-485 communications connect a network of circuit monitors into a power monitoring and control system. The industrially hardened network communicates at speeds up to 500K Baud. It allows a virtually unlimited number of devices to communicate, including circuit monitors, multiple personal computers, POWERLOGIC trip units for low voltage power circuit breakers, MICROLOGIC solid state circuit breakers, and other compatible devices. Extended Memory Options Circuit monitors provide different amounts of non-volatile memory. For example, the CM-2452 can store more than 180,000 values, including dates and times. The memory can be allocated among an event log, a waveform capture log, an event capture log, and up to 14 data logs. The table on the bottom of page 14 shows a typical example of how the user 13

14 Circuit Monitors might configure the available memory for various models. Alarm/Relay Functions Circuit monitors can detect over 100 alarm situations, including over/under conditions, status input changes, and phase unbalance conditions. Each alarm condition can be set to automatically operate one or more circuit monitor relays. Multiple alarms can be assigned to each relay. Up to three form-c, 10 A mechanical relays and one solid-state output are available. On-Board Alarm/Event Logging When an alarm occurs, the circuit monitor can log the event type, date and time, and the most extreme reading during the pick-up delay. When the alarm condition drops out, the dropout date/time and the most extreme reading during the entire event will be logged. The size of the event log can be user configured. Front Panel Features 1 Six-digit LED display 2 Kilo/mega units LEDs 3 Meter indication LEDs 4 Setup/reset parameters 5 Phase indication LEDs 6 Phase select button 7 Select meter buttons 8 Mode indication LEDs 9 Mode select button 10 Optical communications port More than 50 metered values plus extensive minimum and maximum data can be viewed from the large 6-digit LED display. Data Logging Circuit monitors are available with non-volatile memory for storing meter read-ings at regular intervals. A user can configure the size and structure of up to 14 independent data logs to record metered data at intervals from 1 minute to 24 hours. Each data log entry can contain up to 100 values (including date/time). Models CM-2150 and store up to 5,632 values. Models CM-2350 and store up to 51,200 values. Model CM-2452 stores over 180,000 values. Downloadable Firmware The circuit monitor is designed to take advantage of technological advances. As Square D introduces more powerful versions of each circuit monitor, upgrade kits allow the user to install the new capabilities without changing wiring or hardware. This is possible because the circuit monitor has downloadable firmware. The new firmware is transmitted from a PC into the circuit monitor, using the front optical communications port or the rear RS-485 port. The equipment containing the monitor does not have to be de-energized. This allows you to keep your circuit monitors up to date with the latest enhancements, minimizing the fear of obsolescence. Field Installable I/O Modules Field installable input/output modules provide maximum flexibility, while keeping the costs for an application at a minimum. An I/O module can be easily installed on the back of the circuit monitor. Seven different I/O modules are available. The modules provide various combinations of digital and analog I/O, ranging from 1 digital input and 1 digital output to 4 digital Typical Memory Configuration➀ CM-2050 CM-2150 CM-2250 CM-2350/2450 CM-2452 Event Log N/A 200 Events 200 Events 500 Events 1500 Events 1 Data Log N/A 8 Days 8 Days 40 Days 120 Days Waveform Captures➁ N/A N/A 1 3➂ 9 Event Captures➁ N/A N/A 1 3➂ 13 ➀ The relative size of log files is user-defined. This table illustrates a typical memory configuration with one data log that stores the following data hourly: 3Ø avg. amps, volts (L-L, L-N), PF, kw, kvar, freq., 3Ø demand for amps, kw, kva, and kwh and kvarh. ➁ Waveform & event captures are stored in non-volatile memory in the CM-2350 and CM The exact number of waveforms and event captures that can be stored depends on how much memory is allocated to event & data logs. ➂ Up to 20 waveform captures or 8 12-cycle event captures can be stored in the CM-2350 and -2450, depending on memory allocation. The CM-2452 can store up to 60 waveform captures, or cycle event captures can be stored in the CM-2350 and -2450, depending on memory allocation. 14

15 Circuit Monitors inputs, 4 digital outputs, 4 analog inputs, and 4 analog outputs. Two inputs and one output perform special functions. Status input S1 can be configured to accept a demand synch pulse from a utility demand meter. Status input S2 is a high-speed input; it can be connected to an external relay to trigger the circuit monitor s event capture. The KYZ solid-state output is ideal for pulse initiator applications. The form C, 10 amp mechanical relay outputs are extremely flexible each can be configured for remote (external) or circuit monitor (internal) control. In addition, each output can be configured for normal, latched, timed, or one of six different pulse initiator modes. The analog inputs are field convertible from 0 5 Vdc to 4 20 ma. Waveform Capture Square D pioneered the concept of waveform capture. Circuit monitors use a patented, high-speed sampling technique to sample 64 times per cycle on all current and voltage signals simultaneously. The captured waveforms are stored in the circuit monitor memory for retrieval and display by POW- ERLOGIC application software. Waveform captures are triggered internally or externally. A personal computer can send a signal over the communications POWERLOGIC software can show all phase voltage and current waveforms simultaneously, or a single waveform with a data block containing harmonics through the 31st. network or through the optical communications port. An external signal, for example, from an overcurrent relay, can be received through a high-speed input. The waveform capture can also be triggered internally by any of over 100 user-defined alarm conditions, including high or low power factor, %THD, or phase loss. Sag/Swell Detection The circuit monitor can continuously monitor for sags and swells on any metered voltage or current. This feature can help detect and analyze troublesome voltage disturbances that can cause costly equipment down time. The circuit monitor detects sags and swells based on user-defined setpoints and delays (in cycles). When the circuit monitor detects a voltage or current disturbance, it performs an event capture to record the disturbance. This capture is configurable for 12, 24, 36, 48, or 60 cycles. It is performed using the same patented, 64 samples-per-cycle sampling rate as the waveform capture. The user selects the number of pre-event cycles, ranging from 2 to 10 cycles. Thus, the event capture shows the circuit both before and after the disturbance. The event can be date and time stamped to the millisecond, and recorded in the event log. Mounting Options In addition to the standard flush mounting, several other mounting options are available. For applications requiring an indoor general purpose surface mounted (NEMA 1) enclosure, a 3090 SMA-220 is used. The circuit POWERLOGIC software can display sag/swell data captured by the circuit monitor. This screen shows a voltage sag experienced from a single-phase operation of a recloser. 15

16 Circuit Monitors monitor mounts through the door of the enclosure, providing easy access to the rear of the monitor. The enclosure is deep enough to accommodate options, including I/O modules and voltage power modules. The 3090 SMA-220 (left) and the 3090 CMA-100 provide convenient alternatives to flush panel mounting. For applications where depth in the equipment enclosure is critical, POWERLOGIC provides the 3090 CMA-100 and 3090 CMA-110 adapters. The CMA-100 reduces the depth requirements by extending the circuit monitor beyond the front of the equipment. The CMA110 allows the voltage/power module and some I/O modules to be mounted off of the back of the circuit monitor. Control Power Options In addition to CT and PT inputs, the circuit monitor requires control power. The circuit monitor accepts a wide range of voltages including 120/240 Vac nominal or 125/250 Vdc nominal. When the system voltage is 480 Y/277 V, an optional 3090 VPM-277-C1 Voltage/Power Module can be used. This add-on module eliminates the need for PTs and provides control power. The optional 3090 CPM-48 Control Power Module is used when Vdc is available. A 3090 RTM-317 Ride Through Module is also available which provides backup control power for up to 8 seconds depending on the presence of I/O modules. These modules can be conveniently mounted on the back of a circuit monitor or on a nearby flat surface. To complete the offering, Square D manufactures a complete line of control power transformers. Optical Communications Interface The circuit monitor has an optical communications port built into the front panel as a standard feature. Using this port, a portable computer with an optical communications interface (OCI-2000) can retrieve data from the circuit monitor. The OCI-2000 mounts magnetically to the circuit monitor and provides a standard RS-232 interface. This interface can be used by engineers and maintenance personnel to retrieve captured waveforms, event and data logs, and other information without connecting to the network. An I/O module and either a voltage/power module, a control power module, or a ride through module can mount on the back of the circuit monitor. It s easy to tap into a circuit monitor using a PC and an optical communications interface. 16

19 System Manager 3000 Software The System Manager 3000 software (SMS) family and POWERLOGIC Power Monitoring and Control Systems provide a total, integrated system approach to power management. As a result, accessing power information and distributing it wherever it s needed is more easily achieved. Designed primarily for power system engineers, SMS-3000 software brings information from your power system directly to your desktop. The third generation of POWERLOGIC power monitoring software, the SMS-3000 program runs on Microsoft Windows NT and Windows 95 operating systems. The inherent open system and network capabilities of SMS-3000 software help users minimize energy costs, reduce peak demand charges and power factor penalties, and reduce downtime. Whether your power monitoring application requires a single workstation or a full-featured system of networked computers, the new POWERLOGIC SMS-3000 software family offers a variety of functions to make managing and analyzing your power system easier. Scaleable Solution: Client/Server to Stand-alone Client/server applications today are not limited to the computing power of one computer. Instead, they share the workload between multiple computers. With SMS-3000 software, the POWERLOGIC network server handles all device communications, data logging and storage, and alarm management tasks. The SMS-3000 client converts the data it receives from the server into usable formats such as tables, bar charts, and trend plots. It is not necessary for client PCs to be connected to the POWERLOGIC device network; only the POWERLOGIC network server is connected to the device network. SMS-3000 software frees you to position client PCs anywhere on the PC local area network. Client/Server Products System Manager 3000 (SMS-3000) software is the client/server product consisting of one POWERLOGIC network server and one SMS client. The SMS-1000 software product is an additional client application that can be placed wherever it is needed. The client is used with SMS-3000 software via a local area network or wide area network. Stand-alone Products System Manager 1500 (SMS-1500) and Power Monitoring EXPlorer (PMX- 1500) software are stand-alone products with device setup, communication and data displaying capabilities contained on the same PC thus not requiring the PC local area network. SMS-3000 software and SMS-1500 software both support the Interactive Graphics Client. See the back cover for feature comparison between product offerings. Flexibility One of the primary features of client/server technology is flexibility. The System Manager 3000 family allows greater flexibility for power monitoring systems, whether you need a standalone system, multiple POWERLOGIC network servers, multiple clients, remote clients, remote sites, or even a single database to store data from multiple servers. Expand by adding additional clients.

20 System Manager 3000 Software POWERLOGIC MMS Ethernet Gateway Stand-alone software allows logging and displaying of information on one PC. Networking is optional. Remote sites can be automatically dialed via model to upload data from the devices. Plant management can monitor entire plant with graphical one line diagram using SMS and GFX-100 from a PC within the office. Accounting can access the database for cost allocation without having SMS client running. SMS-3000 software creates tend plots of logged historical data. You can display historical information for any quantity from any device in the system. Laptop connection via modem to the POWERLOGIC network server for remote alarm acknowledgement. Etherent connection to local area network Maintenance can monitor and acknowledge alarms on POWERLOGIC network server from a remote PC. Security In addition to the security the Microsoft operating system provides, SMS provides security layers of its own, ensuring that your power system data are thoroughly protected. SMS supports unlimited user accounts, each with a unique name and password. In addition, SMS supports privilege access levels that determine which functions each user can access. Auto-Dial In some cases, you may want to monitor power system information in more than one location. SMS-3000 software offers a auto-dial feature designed to dial remote sites on a scheduled basis and automatically upload the system data. This feature lets users monitor sites across campus or selected remote locations. Historical Logging and Trending The POWERLOGIC system is a collection of distributed databases. SMS automatically collects the extremely accurate historical onboard device data logs as well as collecting and storing data for devices without onboard memory into one centralized ODBC-compliant database. The circuit data can be easily retrieved, displayed and printed in standard historical tabular or trend formats. Custom user selectable styles are also available. For example, this provides selectable quantities and different interval logging for 24 hours or during shift hours. Open Database System Manager 3000 software family complies with the Microsoft Open DataBase Connectivity (ODBC) standards of data storage. This ensures that data stored by the POWERLOGIC network server can be formatted for any ODBC-compliant database. SMS-3000 software uses an embedded Microsoft Access database and is fully tested with both Microsoft Access and Microsoft SQL drivers. Other ODBC-compliant drivers can be installed and used if desired. Tasks Tasks can be performed when an alarm condition is detected, or on a scheduled basis. Available tasks include launching executable programs such as paging software packages, soundwave files, device resets, sending electronic mail, uploading onboard device data, and retrieving or capturing a waveform. Scheduled tasks can be executed hourly, daily, weekly, 20
