    Knee Frequency andUnderfrequency Selection

    g00695812Illustration 19

    The physical differences between the VR3 and theVR3F are minor. The hole for Gain adjustment iseliminated and another terminal is added to theupper row (terminal 10) on the VR3F.

    All VR3F connections to the generator or externaloptions are identical to the VR3. The additionalwiring for the VR3F is shown in the previousdiagram.

    The following information is applicable to bothVR3F designs: Self-Excited and Permanent MagnetExcited.

    • In order to determine the knee frequency, installa jumper from terminal 6 to terminal 10 on theregulator if the generator is operating at 60 Hz.If the generator is operating at 50 Hz, removethe jumper.

    • In order to determine the underfrequency slopeselection, install a jumper from terminal 6 toterminal 8 on the regulator if a 1:1 Volts/Hertzunderfrequency slope is desired. remove thejumper If a 2:1 Volts/Hertz underfrequency slopeis needed.
