Digital Ignition Design Principles
- Reliability and noise immunity: Noise-filtered microcircuit design controls the basic ignition function. Microprocessors, operating at high clock speeds, are used for control purposes only.
- Calibrated timing control: Built-in timing switches are detented in fixed increments. A given switch position always results in the same known timing position.
- Power source flexibility: May be powered from an Altronic engine-driven permanent-magnet alternator or an externally-supplied source of DC power.
- Tolerance to supply voltage variation: DC-powered systems have a regulated input circuit to ensure constant output over a wide input voltage range of 10-32 Vdc.
- Ease of maintenance: Plug-in circuit board modules; quick disconnect connectors; detachable conduit gland plate; ignition testers for quick diagnosis of system components.
- Corrosion resistance: Corrosion-resistant finishes, stainless steel hardware and conformal coating of circuit boards are used throughout.
