Set the weight locations

Overview

The default weight plane has continuous weight positions and an unknown weight placement radius. Change the weight position to discrete if the weight plane has preset weight positions, such as bolt holes or fins.

Discrete positions must be uniformly spaced around the circumference of the rotor at a common radius.

Note: After you collect trial run data, you cannot change the weight locations.

Procedure

  1. From the Balance main menu, press F3 Job Setup.
  2. Press F5 Weight Plane Setup or Enter until the Weight Plane Setup screen appears.
  3. Press F8 Toggle Discrete Contin to select Continuous or Discrete.
    Continuous weight planes let you place weights anywhere, and discrete weight planes let you set weights only at specified locations on the plane. The default is Continuous.
  4. For discrete weight planes, set up the following:
    Option Description
    F9 Enter Number Positions Enter a number between 3 and 100 for the number of positions. The default is 8.
    F10 Enter 1st Pos. Angle Enter the angle of the first position. The position is in the opposite direction of rotation starting from the leading edge of the reference mark, such as the leading edge of the reflective tape. The default is 0.0.
    F11 Toggle Number Rotation Change the position numbers based on the direction the rotor spins. The numbering changes based on the rotation direction. The default is Against Rotation.
    The angular position of the first weight location is measured in the opposite direction of rotation starting from the leading edge of the reference mark (such as the leading edge of the reflective tape or keyway).
  5. Press Enter.
    Repeat this procedure for all weight planes.
