programming,
plug
adjustment procedure and recommended spare
parts list for these specific assemblies are
contained in this Instruction Sheet. Any
differences between these two controllers are
clearly noted. Use Instruction Manual IM-

    Caution: To avoid personal injury or damage to the test equipment remove power before connecting or disconnecting test equipment. The Model 4000 and 4050 controllers contain an LED status monitor which provides a visual means of setting the maximum speed and minimum bias. This LED set up along with an alternate method is given below.

    A trimpot illustration is provided to facilitate the setting of this control. Sufficient range has been provided for drive sizes from fractional through 20 hp for the 4000 controller and up to 125 hp for the 4050 controller. Set you TC control appropriately for your individual drive size as shown in Preliminary Adjustments.
