    The ESD1000 speed control unit precisely controls engine speed through closed loop control connected to a proportional actuator and magnetic speed sensor. It provides isochronous speed control for a variety of engines. The unit is simply installed and adjusted, with protection against reverse voltage and transient voltages. When the speed sensor detects engine speed, the control unit outputs current to proportionally adjust the actuator and maintain a consistent engine speed.

    INTRODUCTION

    The ESD1000 Series speed control unit is an all-


    electronic device designed to control engine speed with
    fast and precise response to transient load changes.
    This closed loop control, when connected to a
    proportional electric actuator and supplied with a
    magnetic speed sensor signal, will control a wide
    variety of engines in an isochronous mode. It is
    designed for high reliability and it's hard-potted to
    withstand the engine environment.

    Simplicity of installation and adjustment was foremost in


    the design. A gain performance adjustment allows near
    optimum response to be easily obtained.

    Other features include protection against reverse


    battery voltage and transient voltages, and fail-safe
    design in the event of loss of speed signal or battery
    supply.
    When the controller receives a speed sensor signal, it is
    DESCRIPTION amplified and shaped by an internal circuit to provide an
    analog speed signal. If the speed sensor monitor does
