Troubleshooting
Fault
Excessive heating
of the vibrator
Vibrator hums
Circuit braker fails
when switched on
High current consump-
tion
32
Possible cause
Wiring wrong / overload
Mains voltage too low
Too much grease in bearings
No grease or not enough grease
in bearings
Foreign body in bearings
Phase interruption
Short-circuit between turns in the
stator winding
Phase interruption
Overload
Short circuit in winding
Natural resonance range of
vibration system
Bounce impacts
Corrective action
Check circuit diagram.
Check mains voltage and cable cross-
section and, if necessary, adjust or
replace cable.
Fill in correct amount of grease.
Fill in correct amount of grease.
Clean bearings, replace if necessary.

nection cable. Correct mains voltage,
replace fuse and/or cable, if neces-
sary.
Replace vibrator.
Check fuse and connection cable,
replace, if necessary.
Check unbalance settings, reduce
unbalance.
