To achieve the target amplitude of 3mm (full amplitude), at least 3 sieves, the collecting vessel and sieve cover must be fastened to the sieve shaker.
If fewer sieves are used, it may not be possible to achieve a target amplitude of 3mm (full amplitude).
In this case, the regulation of the sieve shaker can no longer attain the optimal operating point; the sieve shaker vibrates at a lower amplitude and frequency.
The target amplitude must in this case be lowered accordingly. Once the machine
has warmed up, the target value can under some circumstances be increased
accordingly.
