Employing microprocessor technology in its design, the moderately priced CD200D unit processes angular position input signals from a magnetic pickup sensing drilled reference holes or protrusions. Alternatively, the CD200D also supports the use of a Hall-effect pickup with a magnet disc. This provides accurate and consistent ignition timing referenced directly to the engine’s crankshaft or camshaft. Use of high energy, capacitor-discharge (C.D.) technology, proven in hundreds of thousands of natural gas engine applications worldwide, provides maximum engine performance and can often extend usable spark plug life by three to five times compared to an inductive ignition system. A Windows™-based terminal program gives users access to the entire range of CD200D features, including adjustable output energy, automatic timing adjustment curves (based on RPM or an analog control input such as a load sensor), and the overspeed setpoint. Using this approach, the user can implement those specific features required for a particular application. This software package also displays the system primary and secondary discharge diagnostics. For simple use in the field, these same diagnostics are available to the local operator via a flashing LED on the unit. Remote communications and monitoring via Modbus-RTU are also standard.
