Balancing Application Chapter 8
To Split the Correction Weight
On many rotors, such as a fan, it is not possible to correct the unbalance at the
angle indicated by a measurement run. The Enpac 2500 allows the correction to
be split into two components at points where it is possible to add or remove
weight.
1. Use the DOWN ARROW key to highlight Split Mass, then press the
RIGHT ARROW key.
2. Select Yes to split the weight and press the LEFT ARROW key to save
your choice.
The Enpac 2500 calculates the weight and displays the new
recommendation at the bottom of the screen.
3. To unsplit the correction weight, repeat steps 1 and 2 and select No.
To Modify the Radius
1. Use the DOWN ARROW key to highlight Radius, and press the RIGHT
ARROW key.
2. Use the key pad to enter a new radius, then press READ/OK to save your
entry.
3. The Enpac 2500 calculates the weight and displays the new
recommendation at the bottom the screen.
To Add or Remove Weight
1. Use the UP or DOWN ARROW key to highlight Weight, then press the
RIGHT ARROW key.
2. Select Add or Subtract, and press the LEFT ARROW key to save your
choice.
The Enpac 2500 calculates the weight and displays the new
recommendation at the bottom the screen.
To Take the Residual Measurement
1. Attach the correction weight to the rotor.
2. Start the machine and let it reach operating speed.
3. Press READ/OK to take a residual measurement.
