POSSIBLE CAUSE
1) Missing or incorrect electrical connection
2) Incorrect wiring
3) Mechanical lock
1) Oversized structure to vibrate
2) Incorrect power supply voltage
3) Operating temperature in the room
1) Loosening of the fastening screws
2) Noise level of the bearing
TROUBLESHOOTING
CORRECTIVE ACTION
1)
-Check the power mains
-Ensure the voltage / frequency match the
values reported on the rating plate.
-Follow the connection diagrams
-Always use loop-shaped cable ends.
-Always use delayed overload protective
devices to prevent tripping at start-up.
-The overload protection must not exceed
10% of the max current value reported on
the rating plate.
-Always connect the earthing cable as
specified in the manual.
-The machine can be used with an inverter.
The frequency setting is from 20Hz to the
value on the rating plate.
2)
-Check whether the cross-section of the
cables is suitable according to the length
of the cable.
-Do not use extension cables.
-Check the outside ø of the power supply
cable to ensure the cable gland holds it
perfectly.
-Follow the connection diagrams
3)
-Check whether the shaft can move freely.
1)
-Check the criterion according to which the
motor vibrator was chosen and reduce the
setting of the exposed conductive parts.
-During the commissioning of the vibrating
machines under no-load conditions,
ensure the structure does not lead to
resonance: this phenomenon can result in
an increase in absorbed current and burn
the motor.
2)
-Check the voltage against the data plate
values.
3)
-Bring back the room temperature within
the limits.
1)
-Use screws and washers as specified on
the use and maintenance manual.
-Tighten the screws to the right tightening
torque with a torque wrench as indicated
in the manual.
2)
-Check whether the useful life of the
bearing has been exceeded and, if so,
replace it.
