INSTALLATION INSTRUCTIONS CPU-95 DIGITAL IGNITION SYSTEM MODELS 791950-8/16/18, 791952-18, 791958-16 DEVIATION FROM THESE INSTRUCTIONS MAY LEAD TO IMPROPER OP- ERATION OF THE MACHINE WHICH COULD CAUSE PERSONAL INJURY TO OPERATORS OR OTHER NEARBY PERSONNEL. WARNING: www.altronicinc.com FORM CPU-95 II 4-08 www.altronicinc.com 1 DEVIATION FROM THESE INSTRUCTIONS MAY LEAD TO IMPROPER ENGINE OPERATION WHICH COULD CAUSE PERSONAL INJURY TO OPERATORS OR OTHER NEARBY PERSONNEL. WARNING: 1.0 SYSTEM DESCRIPTION 1.1 The Altronic CPU-95, DC-powered ignition system is a microproces- sor-based capacitor discharge system designed for application on natural gas fueled engines. The system features crankshaft-trig- gered timing accuracy and the capability to vary timing electroni- cally by several means, including an external 4-20 mA control signal connected to the optional Display Module. The system is field-pro- grammable and offers a variety of advanced control methods, emis- sions reduction, primary and spark diagnostics, self diagnostics, serial communications and engine protection features. The system consists of two main parts: an engine mounted Ignition Module and an optional user interface Display Module. 1.2 Various models of the Ignition Module are available: 791950-8 8-outputs, standard 791950-16 16-outputs, standard 791950-18 18-outputs, standard 791952-18 18-outputs, dual capacitor 791958-16 16-outputs, Varispark™ extended duration 1.3 The optional Display Module has a graphical, back-lit LCD display that shows the operating status, engine RPM, energy level, single or double-striking mode, current loop input value and ignition timing. Additional display screens show set-up and diagnostic information. 1.4 To allow for a simple and economical upgrade of existing Altronic CPU-90 installations, the CPU-95 utilizes the same ignition box mount- ing layout, existing Altronic coils, magnetic pickups, Hall-effect pickup and trigger magnet, pickup cables, primary wiring harness and junction box(es). 1.5 Power requirement is 24 Vdc, 5 ampere nominal for typical applica- tions. For Ignition Module 791958-16, use a supply rated for 24 Vdc, 10 amperes. See section 9.2 for details. THE IGNITION SYSTEM MUST BE CONFIGURED PRIOR TO USE ON AN ENGINE. REFER TO SECTION 9.7 TO VIEW THE CURRENT CONFIGURATION. REFERENCE FORM CPU-95 PI FOR INSTRUCTIONS DESCRIBING HOW TO CONFIGURE THE IGNITION SYSTEM. VERIFY EEPROM PROGRAMMING PRIOR TO STARTING ENGINE.
