2 The markets most reliable technology... from the industryʼs most reliable company...caterpillar Caterpillar switchgear with PowerLynx technology has been designed to integrate hand-inglove with Caterpillar on-package microprocessor-based engine control. Exclusively from your Caterpillar dealer, you can now get one-of-a-kind efficiency, reliability and dependability all in one package, something no other manufacturer can provide. PowerLynx technology is innovative, reliable and cost-effective for power generation in both lowand medium-voltage emergency system applications. PowerLynx technology is an advanced, multifaceted microprocessor-based engine generator set control found exclusively in Caterpillar switchgear. PowerLynx Technology Features Fault Tolerance PowerLynx technology provides maximum efficiency and reliability. With other switchgear, if a single component shuts down, the entire system may not operate. With PowerLynx technology, this won t happen because four levels of fault tolerance are built into the system: 1.) True distributed control processors for each power source ensure the system continues to operate even if a single PLC fails. 2.) In the event that the main automation processor fails, PowerLynx technology enables the moving master feature for semi-automatic operation. A redundant main processor is optionally available. 3.) If the touchscreen fails, an Instant Auto switch is provided to place all PowerLynx controls in the Auto position, protecting your facility from power outages. 4.) Distributed manual control in case the automation feature fails. Touchscreen Interface The PowerLynx technology 2000/3000 color touchscreen display is the key to the system s powerful and simple operator interface. PowerLynx 1000 technology uses similar graphical display techniques in a smaller scale monochrome touchscreen format. The screen gives the operator an instantaneous, easily understandable view of the entire system status. This feature is unique to Caterpillar and not found in conventional, hardware-based switchgear. To access system controls, all you have to do is touch the corresponding portion of the screen and you are there immediately. The entire engine generator set can be controlled from one touchscreen. The easy-to-use touchscreen interface makes it possible to view, monitor and perform multiple functions including: Metering Engine gauging Protective relay settings Annunciators Adjust load shed controls and generator demand priority Synchronize and parallel Set modes of operations Voltage and frequency adjustments Display With PowerLynx technology, it s simple. All the critical information you need is displayed in a manner that is familiar to you. raphics look exactly like the meters and gauges on conventional switchgear. At a glance, you can easily see how the system is performing and based on real-time information, you can instantly do what s necessary to correct or optimize system performance. All products are available in three PowerLynx technology versions. Each product family is equipped with features and capabilities suitable for your electrical system s needs. You choose the feature set that is right for your application. Advanced Communications Capabilities PowerLynx technology is equipped with exceptional remote communications technologies, enabling you to control and monitor your engine generator sets from anywhere at anytime. Whether at home, in the office or on the road, you can access controls and information on a real-time basis and respond immediately even control multiple facilities from a single centralized site.

3 Product Description XLM Switchgear using PowerLynx technology enerator Paralleling Switchgear for Emergency Transfer (Xfer) and Load Management control of up to 4 standard configurable engine generator sets with one Utility Source. Automatic Transfer to Emergency upon Utility failure Automatic Start, Synchronize, Parallel and Load Share on a common bus for Emergency operation Closed transition transfer back to Utility upon stable return of power, with soft generator unloading Closed transition Load Management Mode with soft loading and unloading of generator system Closed transition transfer to Emergency Mode to facilitate maintenance, or for storm threat avoidance with soft loading and unloading of generator system Load shed/add enerator demand priority Cost effective, technically superior alternative to conventional ATS arrangement PowerLynx technology brings the power and reliability of microprocessor technology to your generator power application. Through the use of the PowerLynx operator interface touchscreen display with easy to follow graphical presentations, the PowerLynx technology product merges the features of: Power Monitoring Switchgear Automation enerator Set Control Optional emote Communications High-Speed Integrated Control System PowerLynx technology uses a highspeed industrially hardened network for system control. The network is daisy-chained connected, ensuring that the loss of one or more processors will not affect the integrity of the network. This essential feature ensures proper system performance under any condition. Best-in-Class Footprint PowerLynx technology uses fewer than 1/3 of the components of conventional switchgear. This translates to less wiring, a smaller footprint, higher mean time between failures and lower mean time to repair. Integrated Digital Technology Integrated with on-package engine control, PowerLynx has built-in governor, synchronizer, power factor controller and load sharing functions. Caterpillar switchgear products do not require additional discrete components. Advanced enerator Protection Caterpillar switchgear products perform generator protective functions internal to the PowerLynx processor. With PowerLynx technology, you can monitor, process, compare, display and transmit data with a high degree of precision and control and that control translates into high reliability and functionality. Caterpillar power systems protect your power every second of everyday...and seconds can be important where power is concerned. It is crucial to keep a power generation or electrical distribution system operating around-the-clock especially in applications that rely heavily on emergency/standby systems.
