Troubleshooting may only be carried out by authorised qualified staff. The qualified personnel must only use tools suitable for the application.
Fault 1
Vibration motor does not start or runs at too low speed
Possible cause
- Phase interruption
- Mains voltage too low
Troubleshooting
- Check fuse and connecting cable
- Check mains voltage and cable cross section
Action
- Replace fuse and/or connecting cable
- Check if mains voltage is correct, replace cable
Fault 2
Vibration motor speed drops under load
Possible cause
- Wiring wrong
- Inadequate contact of a connection point
- Phase interruption
- Incorrectly dimensioned connecting cable
- Overload
- Mains voltage too low
Troubleshooting
- Check circuit diagram
- Check connection in terminal box
- Check fuse and connecting cable
- Check cable cross-section
- Check mains voltage and cable cross-section
- Check setting of unbalances
Action
- Tighten terminal nuts
- Replace fuse or connecting cable
- Replace cable
- Reduce unbalances
- Check if mains voltage is corrrect, and replace cable
Fault 3
Vibration motor one phase without current
Possible cause
- Phase interruption
Troubleshooting
- Check the connecting cable
Action
- Replace cable
Fault 4
- Excessive heating of stator winding
Possible cause
- Wiring wrong overload
- Mains voltage too low
Troubleshooting
- Check circuit diagram
- Check mains voltage and cable cross-section
Action
- Check if mains voltage is correct, replace cable
Fault 5
- Vibration motor hums
Possible cause
- Phase interruption
- Short-circuit between turns in the stator winding
Troubleshooting
- Check fuse, mains voltage and connecting cable
- Replace vibrator
Action
- Correct mains voltage, replace fuse and/or cable
Fault 6
Circuit breaker fails when switched on
Possible cause
- Phase interruption
- Overload
- Short circuit in winding
Troubleshooting
- Check fuse and connecting cable
- Check unbalance settings
- Replace vibrator
Action
- Replace fuse and/or cable
- Reduce unbalance
Fault 7
- High current consumption
Possible cause
- Natural resonance range of vibration system
- Bounce impacts
Troubleshooting
- Measure current consumption
- Measure current consumption
- Loose fastening
Action
- Stiffen device
- Reduce power of vibrator
- Tighten screws
Fault
- Bearings too warm
Possible cause
- Too much grease in bearings
- No grease in bearings
- Foreign body in bearings
Troubleshooting
- Fill in correct amount of grease
- Clean bearings, replace if necessary
