6.3. Intensity adjustment
The vibration effect with magnetic vibrators de-
pends on the payload and the adjusted air gap
between magnet (Pos. 10 ) and rotor (Pos. 3).
Factory setting air gap:
230 V: 1,8 mm
400 V: 1,6 mm
Stronger effect calls for a smaller air gap and
vice versa. With the protective hood removed,
the air gap is adjusted using pluggable brass
spacer plates (Pos. 14 and 15). With both nuts
(Pos. 7) unscrewed, the air gap can be change
can be changed by removing or adding spacer
plates between rubber pad (Pos. 13) and
rotor (Pos. 3). Both sides need to be adjusted
equally.
The required spacer plates are stocked bet-
ween the ballast discs (Pos. 11).
Noise generated by wrong
adjustment.
The rotor thuds onto the magnet
with too small air gap causing a
loud rattling noise. This is imper-
missible and has to be stopped
by widening the air gap.
