Change of the system's natural frequency
due to a broken spring
Undo screws of the spring assemblies, check springs,
and replace broken or damaged springs. CAUTION!
Cause for a broken spring is often too high oscillation
amplitude. --> Check air gap
The drive is improperly adjusted, i.e. the
system's natural frequency does not
match the exciting frequency
Adjust the drive by changing the spring stiffness:
Change the position of the adjustment plates. Tighten
the screws of the spring assemblies. CAUTION! Ad-
just the conveyors according to the operating manual!
The weight (moment of inertia) of the
conveyor bowl exceeds the maximum
permissible limit value for the correspond-
ing drive
Carry out a mass balance according to the instruc-
tions in the operating manual
Foreign part jammed in the air gap be-
tween magnet and rotor
Remove foreign part
The conveyor transmit vibrations
Cause of fault
Fault repair
The conveyor rail is not sufficiently fas-
tened to the corresponding drive
Tighten fastening screws, check thread, if necessary

Tighten fastening screws, check thread, if necessary
The air gap between magnet and rotor is
too small (striking) or too large
Set the air gap according to the operating manual
