Description

Product Overview

The SA-4489 / APECS 4500 electronic controller provides maximum control and optimal engine performance. By adjusting the fuel control lever with a Woodward proportional actuator the 4500 system controls and limits engine speed. By adjusting to load, temperature and fuel quality it optimizes your engine’s operating efficiency

Key Features

• Control capabilities include engine/ ground speed control, rate of acceleration control, drive-by-wire operation, variable speed operation, and power takeoff operation.
• Two user-selectable auxiliary outputs can be configured for glow plug control, autocrank control, engine shutdown, remote diagnosis, and mode lamp.
• Calibration is simple using ACT, Woodward’s proprietary software. The controller can be calibrated on any IBM-compatible PC, allowing for easy customization and re-programmability.
• Universal speed input permits use with magnetic pickups, coil-type spark ignition systems, magneto spark ignition systems, and Hall Effect sensors.
• Internal diagnostics monitor engine operation and the status LED indicates malfunctions through coded flashing. Built-in engine protection capability can monitor engine coolant and oil pressure.
• Sealed, waterproof connectors assure reliability in harsh environments.

Technical Notes

Programmable Features:

• Analog speed setpoint input is suitable for use with a potentiometer or an accelerator pedal position sensor (idle verification available).
• Actuator current protection protects actuator from burning out.
• Autocrank permits remote operation of engines.
• Two auxiliary outputs drive a lamp or relay.
• Glow plug control
• Droop governing allows non-isochronous speed governing.
• Engine protection input protects against adverse conditions such as loss of engine oil pressure or excessive coolant temperature.
• Engine start calibration expedites special startup operations such as warm-up speed, reduced governor gains, missing speed signal
• Overspeed/underspeed protection
• PID gain adjustment allows governor response to be adjusted by user.
• PTO switch input permits selection between analog speed setpoint input and switched speed setpoint inputs in mobile applications.
• Switched speed setpoint inputs allow multiple speed settings using switches. This feature can be configured together with the analog input (speed pot) for a variety of speed select options.
