Troubleshooting
28
Fault
Possible cause
Corrective action
Excessive heating
of the vibrator
Wiring wrong / overload
Check circuit diagram.
Mains voltage too low
Check mains voltage and cable cross-
section and, if necessary, adjust or
replace cable.
Too much grease in bearings
Fill in correct amount of grease.
No grease or not enough grease
in bearings
Fill in correct amount of grease.
Foreign body in bearings
Clean bearings, replace if necessary.
Vibrator hums
Phase interruption
Check fuse, mains voltage and con-
nection cable. Correct mains voltage,
replace fuse and/or cable, if neces-
sary.
Short-circuit between turns in the
stator winding
Replace vibrator.
Circuit braker fails
when switched on
Phase interruption
Check fuse and connection cable,
replace, if necessary.
Overload
Check unbalance settings, reduce
unbalance.
Short circuit in winding
Replace vibrator.
High current consump-
tion
Natural resonance range of
vibration system
Measure current consumption, stiffen
device.
Bounce impacts
Measure current consumption, reduce
power of vibrator.
Check fastening, tighten fastening
screws, if necessary.
