Default number of unbalance discs per vibrator
There are 2 possibilities to adjust the unbalances:
1. The unbalance adjustment (fine adjustment) is carried out by removing one lamella disc on
each side. All centrifugal values in % can be adjusted as specified in the table.
The removed lamella discs must be replaced by compensation washers (available from
NetterVibration) of identical thickness and identical inner diameter.
2. The unbalance adjustment (coarse adjustment) is performed by turning one lamella disc on
each side by 180° on the shaft.
Twice the number of lamella discs turned by 180° becomes ineffective.
