Altronic, LLC – A Member of the HOERBIGER GroupEPC SERIESEngine Performance Controllern Improve engine performance and efficiencyn Electronic control of ignition timing and air/fuel ratio n User-configurable for any enginen Fail-safe design features and fault annunciation n Seven discrete outputs for sequence controln 8-digit LCD display of status and operating parameters n RS422 communications interfacen CSA-Certified for Class I, Division 2, Group DHazardous AreasThe Altronic EPC-200C Engine Performance Controller is de-signed to maximize engine performance and efficiency. Micro-processor-based, the EPC electronically controls ignition timing and air/fuel ratio replacing the traditional pneumatic control system for these functions. Engine RPM plus up to four other analog inputs can be used as control variables; typically, these would include fuel manifold pressure, air manifold pressure and air manifold temperature. The four inputs and two analog outputs are in the form of 1–5 volt or 4–20 ma signals for easy interfacing with available transducers. The EPC is specially designed to operate in conjunction with Altronic II-CPU and Altronic III-CPU.In addition to the two analog control functions (ignition timing and air/fuel ratio), the EPC-200C also has six user-programma-ble solid-state relay outputs related to the common start-up se-quencing functions such as purge, overcrank, crank disconnect, flooding, etc. A seventh discrete output provides a signal in the event of overspeed, overload or loss of any input; if this occurs, timing and air/fuel ratio are set to preset values. In addition, there is a manual override mode to allow changing and checking of program data while the engine is running.The EPC-200C has a RS422 interface for communications capability with other process or control computers.CERTIFIEDCLASS I, DIVISION 2,GROUP DTypical ApplicationExample: Turbocharged Gas Engine with Wastegate Controllerfor Air Manifold PressureThe chart indicates the most common input variables used. The fifth input channel gives additional flexibility and capability for more sophisticated control programs.For Ignition Timing control, the user chooses one input (for exam-ple, RPM) as the primary control factor. Other factors are used to appropriately modify the timing curves for load and temperature. For Air/Fuel Ratio control, fuel pressure is the primary control factor with air manifold temperature as a modifier. Other control strategies are possible, for example, based on different inputs such as fuel BTU value or exhaust oxygen content.EPC-200 FeaturesGeneral Operation — The EPC-200C performs the functions of a typical pneumatic control system for a gas engine with exhaust-driven turbocharger. The outputs are controlled by RPM and up to four other variables. Response to the inputs is controlled by entries through the the EPC’s dealed membrane keyboard, giving the user total access to the operating parameters.Keyboard Entry by User — Operating curves are entered inj (x,y) coordinate format: other data is entered and displayed in com-mon engineering units (RPM, psi, degrees F., etc.). No algebra or computer programming knowledge is required. Access to critical control variables is password-protected so that accidental contact with the keyboard has no effect.Diagnostic Capability — Diagnostic messages warn of various ab-normal conditions while the engine is in operation or the first-out fault cause for the error output which can be used to alarmk or shut down the engine. Loss of any specific input or out-of-range conditions are examples of the factors which are specifically an-nunciated.Rs422 Communications Capability — Communications capability is provided for interfacing to process control computers. The data on any channel can be read, including the ignition timing and wa-stegate position values. All setpoints can be read and/or altered remotely. RS422 signals have the capability for long distance transmission. In addition, software for direct, readable display and control from a remote IBM-compatible PC will be available.4-20mA Outputs — The two major contol outputs, Ignition Timing Retard and Wastegate Position, are output as 4-20mA (1-5 V.) signals. Additionally, the user has control over the Proportional Band and Reset Time Response values. These determine how the EPC responds to changes in input data; an important feature for any control device interfacing with a large, mechanical machine. The EPC-200C performs the functions of a typical pneumatic control system for a gas engine with exhaust-driven turbocharger. The outputs are controlled by RPM and up to four other variables. Response to the inputs is controlled by entries through the the EPC’s dealed membrane keyboard, giving the user total access to the operating parameters.Display Capabilityn Display value of all analog input signalsn Display the output value for ignition timing, air manifold pressure and waste gate positionn Display all (x,y) coordinate valuesn Display PI response valuesn Diagnostic channels for error messages when operating or first-out fault Data Entered by User1.

Designs are available with a host of options and accessories to fit the requirements and desired configurations of virtually any installation . Multi-stage metal-enclosed medium-voltage capacitor banks are designed for systems such as industrial, commercial, and utility power systems involving motors, feeder circuits, and transmission anddistribution lines where power factor improvement is required .Metal-enclosed medium-voltage power factor correction system2Technical Data TD02607011EEffective June 2021Metal-enclosed medium-voltage power factor correction systemEATON Application description Utility customersMetal-enclosed power factor correction systems are fully assembled, tested, and ready for installation . Very little field assembly is required . Installation and maintenance costs for metal-enclosed systems are low compared to pole and rack mounted capacitor banks . Metal-enclosed systems and detuned filters are less vulnerable to wildlife and airborne contaminants that can causetracking and faults . In addition, metal-enclosed systems significantly reduce the risks and the associated liability involving arc-flash and untrained personnel . All live parts are contained in a grounded, key interlocked enclosure, and no internal hardware is accessible . Metal-enclosed systems are aesthetically pleasing due to their low profile, and can be painted to match the surrounding architecture . These are just some of the reasons more and more customers are using metal-enclosed capacitor and detuned filter systems .Industrial customersMany industrial power users can take advantage of the benefits associated with medium-voltage power factor correction . Medium-voltage solutions usually support the scale and scope of larger utility services . Medium-voltage applications can be found in the following types of industries: automotive, pulp and paper, plastics, petrochemical, and heavy manufacturing . Individual fixed capacitors provide power factor correction directly at the cause of the problem, such as large horsepower MV motors . Medium-voltage systemsallow large facilities to correct power factor at or close to the point of common coupling (PCC), where the utility electrical system meets theirs . This allows correction for an entire facility, instead of having to correct at multiple locations . The NEMA T 3R design also allows the system to be placed outdoors, saving valuable manufacturing floor space . The savings can be significant in materials, installation costs, and floor space . In short, medium-voltage solutions can provide a cost-effective alternative to many local low-voltage power factor correction units .Commercial customersMany commercial customers are purchasing power from their utility at higher voltages today (2 .3–15 kV), and can also take advantage of medium-voltage power factor correction systems . These solutions can meet the needs of large office complexes, hospitals, and universities, among others . The benefits of safety (key interlocking, no exposed live parts, etc .) and aesthetics(low profile, can be painted to match the environment) both meet the needs of these applications where there are large numbersof untrained personnel in proximity of electrical equipment .Safety and aesthetics are just two compelling reasons to use metal-enclosed PFC systems .AdvantagesEaton has over 75 years in the capacitor systems business . Y ou can count on Eaton’s extensive power systems experience to provide a world-class solution to satisfy any power factor need . Quality and reliability are of paramount importance to not only the Eaton engineering team, but are also the backbone of all Eaton products and services . This commitment to quality means the customer can have a great deal of confidence with the medium-voltage capacitor or detuned filter solution from Eaton .BenefitsEase of installationEaton makes installation easy . All systems are completely assembled in the factory, with all equipment pre-wired and pre-tested for easy on-site installation . Only shipping splits must be connected in the field . Splice kits connect bus systems, and control wiring is easily connected at each enclosure . Current-limiting fuses, contactor assemblies, and the incoming switch assembly can be removed from the enclosure if needed . Line terminals are completely accessible from the front of the system . Bottom steel barrier at top of base channel is standard .Personnel safetyA positive mechanical isolating switch with visible disconnectcompletely grounds and isolates the unit from the line connectors . All medium-voltage doors are mechanically interlocked with the disconnect switch . Key interlocks are provided standard on allenclosure doors, and can be coordinated with upstream disconnect devices . The low-voltage control section has a separate door-in-door design, and is segregated from the medium-voltage sections so that an operator can work in that section safely .Ease of maintenanceAll components are accessible through standard compartment doors, facilitating routine inspection or parts replacement . A viewing window is standard on all compartment doors, providing visual access to fuse and contactor status .FlexibilitySystems are expandable .
