Excluding Sales Tax
The Altronic CPU-95, DC-powered ignition system is a microprocessor-based capacitor discharge system designed for application on natural gas-fueled engines. The system features crankshaft-triggered timing accuracy and the capability to vary timing electronically by several means, including an external 4-20 mA control signal connected to the optional Display Module. The system is field-programmable and offers a variety of advanced control methods, emissions 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.
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

Key Features
- Display Capability support
- Value of timing control signal (4-20mA)
- Relative spark plug voltage indication by cylinder
- Engine speed (in RPM), Engine overspeed setpoint
- Diagnostic messages Spark Characteristic Control For improved engine performance and combustion stability, ignition of lean mixtures for emissions reduction or improved starting and loading characteristics:
- Double-striking mode (selectable ON/OFF) VariSpark™ mode (selectable ON/OFF, VariSpark™ model only)
- Manual or automatic ignition energy level control (3 levels) Ignition Timing Control Modes Local and remote control of ignition timing (global or individual cylinder) allows engine starting and running performance to be optimized.
- One-step timing change vs. input signal or RPM Keypad control via display module
- Terminal program control via serial port
- Analog 4 to 20mA control
- Timing control vs. RPM Serial Communications to PC or Engine Management System All system features, display data and configuration inputs are accessible via an integral RS-485 serial port.
- A dual port display module enables simultaneous use of both the system display and a supervisory control system utilizing Modbus RTU. System Configuration Engine-specific configuration parameters are contained in a plug-in memory (EEPROM) which can be moved to a spare unit if necessary. The memory can be configured in the shop or on location using a personal computer connected to the serial port.

- Number of gear teeth or flywheel holes sensed
- Timing control vs. 4-20mA and RPM Diagnostics, Testing, Shutdown Capabilities Advanced and patented diagnostics, self-test, and alarm/shutdown capabilities are included with each CPU-95 system.
- Primary and secondary discharge faults identified as to cylinder
- Status of system pickups
- Verification of the number of teeth/holes.
- Test firing of selected cylinder(s) (optional)
- Overspeed condition
- Alarm and shutdown outputs.
