TROUBLESHOOTING TABLE
PROBLEM / CONDITIONS
POSSIBLE CAUSE
WHAT TO CHECK
POSSIBLE SOLUTIONS
Vibrator is not working and
no audible noises
Lack of current from
feeding line
Check tension among phases in terminal block,
protections (switches, fuses), and/or damages
to feeding cable
Restore or replace protections and/or feeding
cable and/or terminals and check wiring in the
terminal block
Vibrator is not working but
there is an audible buzzing
Lack of one phase of
the line
Check line tension among phases in terminal
block and protections (switches, fuses) and/or
damages to feeding cable
Restore or replace protections and/or feeding
cable and/or terminals and check wiring in the
terminal block
Lack of one phase of
the motor
Check resistance of phases in terminal block
and possible disconnections of thimbles on
terminals
Replace motor thimbles and/or check wiring in
the terminal block, or re-wind the motor
Vibrator seems to start, but
immediately switches off
Short circuit between
phases
Check resistance of phases in terminal block
and possible contacts among conductors of
feeding cable
Eliminate contacts among conductors or re-
wind the motor
Overload protection
activated
Check that rotor shaft rotate free
Remove excess grease
Phases to ground
Check resistance between phases and ground
Re-wind the motor
Vibrator does not reach the
nominal speed
Wrong electric
connection
Check that connection is according to diagram
indicated on nameplate
Proceed to correct connection according to
diagram
Tension of line is
too low
Check tension of line between phases in
terminal block
Replace feeding cable with a bigger one
Wrong direction of
rotation (working
in pair)
Check the direction of rotation
Reverse the direction of rotation
Incorrect isolating
system of the
equipment
Check characteristics of the isolating system
and its deflection
Replace and/or modify the isolating system
Intensity of vibration
too high for the
application (silos,
hoppers, ecc)
Check excentric weights setting
Reduce the intensity of vibration adjusting the
excentric weights
Excess of grease and/
or not suitable grease
Remove weights covers and check the
situation
Remove excess grease and/or substitute with
recommended type
Ambient temperature
too low
Check temperatures
Use a suitable model to ambient conditions
Vibrator does not reach the
nominal speed and makes
a metallic noise
Loose fixing bolts
Check that fixing bolts are correctly tightened
Tighten fixing bolts
Fixing area for vibrator
base is not evenly flat
Check flatness of the surface for vibrator
base fixing
Make the surface flat according to manual
recommendations
Not even contact
between vibrator base
and fixing surface
Check if any incrostation and/or dirt between
vibrator base and surface
Remove incrostations and clean the surface
Weights covers are
damaged
Check that weights can rotate free and that
covers are not touching other structures
Fit and/or substitute the weights covers and
grant a correct distance from other structures
The equipment
touches other
structures
Check the isolating system and the distance
from other structures
Substitute and/or modify the isolating system
and/or grant a correct distance from other
structures
Vibrator makes a metallic
noise
Protection covers not
correctly fixed
Protection covers bolts are not correctly
tightened
Tighten protection covers bolts
Bearing (or both
bearings) damaged
Check the type of noise by experienced
personnel
Substitute bearing (or both)
After a working period
the protections stop the
Vibrator
Ambient temperature is
too high
Check temperature
Bring temperature within recommended limits
Bearing is damanged
Check the type of noise by experienced
personnel
Substitute bearing
Wrong direction of
rotation (working
in pair)
Check the direction of rotation
Reverse the direction of rotation
Excess of dirt laying on
vibrator surface
Check the situation
Remove the laying dirt
