Troubleshooting
Action
Excessive heating
of the vibrator
Wiring wrong / overload
Check circuit diagram
Mains voltage too low
Check mains voltage and
cable cross-section
Correct mains voltage, re-
place cable
Too much grease in bearings
Fill in correct ammount of grease
No grease or not enough
grease in bearings
Fill in correct ammount of grease
Foreign body in bearings
Clean bearings, replace if necessary
Vibrator hums
Phase interruption
Check fuse, mains voltage
and connection cable
Correct mains voltage, re-
place fuse or cable

switched on
Phase interruption
Check fuse and connection
cable
Replace fuse or connection
cable
Overload
Check unbalance settings
Reduce unbalance
Short circuit in winding

High current consumption
Natural resonance range of
vibration system
Measure current consump-
tion
Stiffen device
Bounce impacts
Measure current consump-
tion
Reduce power of vibrator
Loose fastening
Tighten screws
