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 eld-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.
