SECTION 3 - Use and maintenance of MVCC vibrator
3.0 INSTALLATION AND ELECTRICAL CONNECTION
Before installation and if the motor-vibrator has been stored for over 12 months, remove
a weight cover and check that the shaft is free to turn .
ITALVIBRAS vibrators can be installed in any position.
The vibrator must be rigidly fixed to a perfectly flat structure (0.25mm) with bolts and
nuts type 8.8. Use a torque wrench (table page 72).
Attention: Check the tightness again after a short period of operation.
All MVCC vibrators are supplied with a 2,5m cable type FROR 2x2,5 mm
3/1200, MVCC 3/1500: 2x6mm ).

The power supply cable must be connected to the electricity by an installer, in
compliance with the current safety provisions.
Always check that the power voltage value correspond to these indicated on the
vibrator identification plate before powering the equipment.
Important: consult the technical data, electrical characteristics, rated current
and starting power draw when choosing the electrical equipment to start/stop
the machine and protect against overloads. Also opt for delayed magnetothermic
switches to prevent release during the starting phase which may be longer at
low ambient temperatures.
Check that the current draw does not exceed the nameplate value.
If this is not the case:
- Check that the flexible system and structural elements comply with the current use
requirements.
- Reduce the vibration force by adjusting the weights until the absorbed current value
returns within nameplate values.

Remember to operate the electric rotary vibrator for short periods during set-up
in order to prevent damage to both the vibrator itself and to the structure in the
event of faults.
The vibrator must always be started/stopped by setting the power switch to the ON/OFF
position respectively.
3.1 REGULATING THE VIBRATION INTENSITY
(MVCC

ATTENTION: This operation must only be carried out by specialized personnel
after the electrical power supply has been disconnected.
- Remove the weight covers (n° 3, pages 36-39).
- Unscrew the nuts at the shaft ends (n°4, pages 36-39).
- Turn the adjustable weights (n° 7, pages 36-39) on both sides until they have been
regulated in the required way, as shown by the graduated disc (N° 9, pages 36-39) as
percentage of the maximum centrifugal force.
- Tighten the nuts and reassemble the weights covers, checking that the seals (n° 6,
pages 36-39) are on good conditions and have correctly fitted into their housings.
3.2 MAINTENANCE
The vibrators need no particular maintenance.
Before servicing a vibrator, wait until the temperature of its casing is not more
than 40°C and check that it has been disconnected from the electricity supply.
Only use genuine ITALVIBRAS spare parts.
To replace internal parts the vibrator must be disassembled according with the following
indications:
- Disconnect the electricity supply and remove the vibrator from the vibrating machi-
ne.
- Remove the weight covers (n°, pages -).
