The Balancer
Introduction
The balancing process is based on standard measurements of amplitude and phase on the speed frequency.
The VA3 balancer includes many special internal functions, which remove the influence of noise and speed
changes etc. If you are not familiar with on-site balancing method, we recommend reading professional
literature before you proceed.
Planes and Points
We would like to explain the difference between the words 'plane' and 'point'. The sensor is mounted to the point
or points (dual channel reading). The trial mass and final masses are mounted to the plane or planes. Some
people talk about measuring on planes, but this is not correct. In case of overhanging rotor there is no direct
relationship between points and planes.
We use the labels A and B for points and 1 and 2 for planes.
The Project
The Project is the base structure in the Balancer mode. It corresponds to one balancing job. You can use the
same Project for repeated jobs on the same machine. The measured data will be re-written.
The Project contains all measured or entered data, which are used during the job. The typical scheme looks like
the following list of steps:
- Create the project.
- Enter the parameters of the project.
- RUN 1 - Initial measurement of the vibration amplitude and phase is taken at the required number of points.
- Place a trial mass on the plane. Repeat this step on the second plane if required.
- RUN 2 - Trial mass response measurement is taken. Repeat this step on the second plane if required.
- Place final masses put on all planes.
- RUN 3 – This checks the effect (success) of the balancing job.
- Trim - Additional trimming can be carried out for better results.
The Project Screen
Every step is displayed on its own screen. You can move between screens by pressing the left/right
arrow buttons.
This movement enables you to return back anytime.
Attention: When you return back to the job screens and take the reading again or enter the value, then the
measured data will be erased in all screens after the current screen. The reason is simple; the implications are
derived from every screen to the following screens. When you repeat the measurement, you change the
parameters for those implications. That is why all the following screen implications must be removed and you
have to take all the necessary readings again.
The first screen
The list of saved projects or the Empty label is displayed on the first screen. Select one project or use the Menu/
New Project. The following functions for managing projects are also enabled (Menu button).
