Example:
NEG 50120 / 50 Hz has a total of 6 unbalance discs (3 discs per side: 2
fixed, 1 adjustable).
If a centrifugal force of 88% is desired, the adjustable unbalance discs are
rotated anticlockwise on both sides into the fourth grid position.
centrifugal force 100 %
centrifugal force 88 %
The unbalance setting of the unbalance discs
of the type XS is carried out on the scale on
the fixed unbalance.
The centrifugal force can be steplessly adjust-
ed by turning the outer unbalance discs and
adjusting them at the partial strokes. After ad-
justing the unbalances, the nuts and screws
must be tightened with the specified torque.
Observe the recommended values for screw
sizes and tightening torques in chap. Technical
data, from page 11.
The centrifugal force can be adjusted according to the following table:
